Thoughts on Horse Barn Heaters

Orr-Heating BlogA client recently asked one of our architects for recommendations on adding heaters in the barn.

When an owner requests forced air electric heating system in the stalls, we advise against it for several reasons:

1) Forced hot air rises and heat stays at the ceiling level, adding unnecessarily to the cost of operating the barn. Blackburn barns are designed to allow air to escape thru the roof vents, so at a minimum sending heat skywards doesn’t make financial sense.

2) Forced air systems move airborne particles around the space and, given the size of the barn and the heat loss expected thru the roof vents, heaters must pump a lot of air at a high velocity to provide sufficient heat to keep the barn to a temperature that might be considered sufficient (which varies with personal preference).

3) Forced air heaters are unhealthy for horses because they spread dust, mold and disease throughout the stable area. Horses give off a tremendous amount of moisture, especially in winter, and that moisture contains bacteria and other viral matter that can be harmful to their sensitive respiratory systems and spread to other horses. If a barn is closed up too tightly (the barn needs to breathe in all temperatures) the barn can become too warm and increase the opportunity to breed bacteria that would normally be ventilated out of the barn. There may be some exceptions for older and ailing horses but a tightly-closed, heated barn is often more harmful than helpful. We recommend discussing with your vet exceptional conditions that may be needed for young, aging or infirm horses.

Strategically placed infrared heaters can be a good choice to keep the chill at bay in human-occupied areas.

Infrared is another term for radiant heat. For example, a stove, fireplace, oven or even our own sun emit infrared (radiant) heat energy. That energy converts to heat, warming the surrounding air.

In a barn, infrared heaters are specially made to produce safe, comfortable radiant heat. When asked by a client, we specify that heaters are directed downward from the ceiling toward a target area below. In an equestrian facility, infrared heaters can be directed toward wash stalls and/or and grooming areas, or down a common walkway, between horse stalls or even in riding arenas.

Blackburn Architects uses two scientific principles to ventilate horse barns – the Bernoulli Principle and the Chimney Effect – vertically removing harmful bacteria and ammonia gases that can cause disease and odors. Providing heat for the horse by forced air does little if anything to help the horse except create harmful, unhealthy conditions.

When requested by a client, we can specify heated floors. Infrared tube heaters emit soft, comfortable radiant heat energy without creating drafts. Infrared heats the ground. Warm floors = warm bodies & feet.

As we all know, horses can naturally withstand colder temperatures better than hot temperatures. If permitted to keep their winter coat and remain dry, horses can withstand even very low temperatures. For colder temperatures, we recommend keeping cold drafts off the horses by closing Dutch doors at stalls (add weather stripping to the doors if needed) and closed aisle doors. In other words, if a horse can stay dry and get out of a steady breeze or draft they have a much better chance to maintain their own health.

Fencing When Designing a Horse Farm: Options to Consider

Sagamore_insta

Fences are one of the most common discussion points among the Blackburn team and clients when we’re designing an equestrian facility. The options listed below are certainly not exhaustive but reflect what we commonly find in many of our projects.

Some options are better suited for pastures, while others are more appropriate for small stall turnouts. We’ve tried to identify a variety of approaches that meet the safety needs for horses, limit maintenance needs, and often fall within neighborhood guidelines. 

1. Steel rail fencing is an option for stable turnouts. The material is available in a thinner profile so it isn’t as visually heavy and it can be painted black or another dark color so that it does not have the “ranch” appearance seen with galvanized steel pipe corrals. The up-front cost is higher but the material is durable and will have little-to-no maintenance needs.

2. Woodguard polymer coated wood fencing is treated wood with a non-toxic, non-chipping surface covering. The wood grain is still visible but the finish has some of the plastic texture of the polymer. This product allows for fencing to be constructed similar to a wood fence, with the rails attached to the face of the posts. The result is a stronger, safer fence. Woodguard has a 20-year warranty. The cost is similar to wood board fencing but the maintenance needs are less. While the manufacturers state that this product is resistant to cribbing, we would recommend that a hot-wire be provided at the top rail to discourage the horses from chewing. This material would be acceptable to use for both stall turnouts and paddocks. It offers the appearance of a traditional 3- or 4-board wood fence without the significant maintenance demands. https://www.wood-guard.com/horse-fencing/

3. High Tensile Polymer (HTP) comes in both rail and wire styles and is typically mounted on wood posts. The rail is typically 5” wide and from a distance will appear similar to wood board fencing. Because wire fencing has a lower visibility, we suggest using a thicker top board so that the horses can more easily identify the barrier. The HTP materials’ inherent flexibility makes these products durable and resistant to horses leaning on or running into the fence. Typically, these are more suited to large pastures or for perimeter fencing and less so for stall turnouts. The darker colors tend to exhibit a chalky appearance over time.

4. Rubber fencing is a durable, flexible, and low profile fencing material and is similar to the HTP fencing. We’ve not seen this product used as often and we understand that there’s a risk that the strings of the fabric (which is an internal support for the rubber) can become exposed and offer a hazard for horses to chew on. A hot-wire at the top of the fence may combat this risk.

The advantages of rubber, HTP or any type strap fencing is the posts can be set further apart which is useful when its highly visible and you want to minimize the number of posts. The fencing is flexible and resists breaking when a limb or tree falls on it therefore it’s a good material for perimeter fencing large acreage and where it encounters wooded areas. This is safer if/when a horse runs into the fence; especially a problem on larger paddocks when horses can get some speed and not be able to slow down.

5. HDPE is a post and board fencing material. It’s stronger than PVC and performs better in all weather conditions, but the primary issue is in the assembly of the fence. The rails are set between posts, instead of fastened to the face, and can pop out if the fence is not secured properly. Its requires more frequent posts which tends to look busy and it’s difficult to bend or angle corners because of the assembly method. The Blackburn team isn’t particularly fond of this material because it can look clunky and isn’t the safest option. http://www.amberwayequine.com/products/hdpe-fencing-2/

Recommendations for Adding Glass in a Horse Barn

WinterFarm_Insta

What’s the safest way to incorporate glass in a horse barn? If you’ve been following our work, you already know that Blackburn Architects’ mission is to promote as much natural light and ventilation in horse structures as possible. Naturally, this means we add a lot of windows to our designs. In its safety recommendations for the stable, Rutgers NJ Agricultural Experiment Station cautions that “windows need to be inaccessible to horses and livestock, covered with bars or screening and made of safety glass.” (https://esc.rutgers.edu/fact_sheet/safety-recommendations-for-the-stable-barn-yard-and-horselivestock-structures/). So how do our architects protect the horses and still use a lot of glass in our designs?

1. Use Tempered & Laminated Glass
We recommend that all glass in a horse stable be tempered, including glass that’s laminated. Tempering and lamination do two separate but similar things to increase the safety of glass if/when it breaks: Tempering makes the glass break into small chunks as opposed to slivers and shards, while the lamination gives the glass a slightly greater resistance to breaking and keeps the glass in place when and if it breaks.

Laminated glass consists of a clear plastic laminate sandwiched by glass on both sides. Since horses have access to both sides of a glazing unit, ideally both sides should be laminated and tempered. If this approach is too costly for your budget, stick with everything being tempered and omit the lamination. Laminated glass does not always age as well as tempering. The laminate can shrink and pull in from the corners of the glass, and eventually become visible over time. We prefer tempering.

2. Minimum Thickness of Glass and Airspace
To arrive at the minimum thickness of glass, work backwards from the depth of the frame, minus about 1/4”. Each glass manufacturer determines what spacer sizes they offer. Understand that the more airspace you can allow the better, but each manufacturer works with a few different pre-set size spacers. Use the largest one that still allows the glazing unit to fit within the frame.

3. Special Considerations for Cold Climates
In cold climates, we specify glass with a high solar gain and low emissivity. In technical terms, the glass meets the following guidelines:
1. A Solar Heat Gain Coefficient (SHGC) around 0.55
2. A U-value of less than 0.33
3. A higher value Visible Transmission (VT)
4. Use double-paned glazing units with low-e gas that has a vacuum sealed gasket between the panes of glass. The pocket between panes of glass is filled with an insulation gas, most typically argon.
5. Consider using low emissive (low-e) glass panes (low-e prevents the transfer of heat from warm to cold). The low-e coating (typically a metallic oxide) should be on outside of the innermost pane of glass.

There are pros and cons that should be considered with each option 1-5 above. For instance, with #4, over time and if the gasket seal fails, you can begin to see condensation between the panes of glass. Whereas with #5, you may be able to see the coating from certain angles, especially if you are wearing polarized sunglasses. Since the advantages are a bit more obvious, and similar to one another (i.e. tempered vs laminated, and low-e gas vs low-e coated glass), here is a summary of some of the disadvantages to each option:

Tempered only – glass may still shatter (in harmless pieces) and fall to the ground.
Laminated only – laminate can discolor over time and shrink in from the corners of the glass.

Low-e gas filled glazing unit – if the gasket fails, condensation can form in between the glass.
Low-e coated glass – may be visible in certain light conditions, or when wearing polarized sunglasses. You can sometimes see this on automobile glass.

To summarize, a good starting place for adding glass to your barn begins with tempered glass, meeting the SHGC and U-values recommended above. A step beyond this is low-e coated glass, since with #4 (low-e gas) you can expect the gaskets to fail at some point, and the glazing unit will need to be replaced. If the coating of the low-e coated glass is too “visible,” then low-e gas may be the better option, with the expectation that you may need to replace some of them again in 10 to 20 years, if and when the gaskets fail.

The Zucker Race Horses

IMG_1193

IMG_1190

A job interview is not exactly an expected set up for an art sale. So when Lauren Zucker (now Richards) came looking for a job at Blackburn Architects some years ago, she found one. One she didn’t accept because graduate school had a stronger pull.

But in a strange twist, John Blackburn liked the student artwork she showed in her portfolio so much he bought it. Two beautiful Lauren Zucker black oil bar on paper works hang in the Blackburn Architects’ offices in Washington, DC. The large 48’x60’ framed paintings are captivating for the brush strokes evoking the fevered jostling of racehorses leaving the starting gate. They are lovely paintings, and visitors to the office often comment on them.

She described her work this way:

Jockey: Horse
The Race

The Race: Within the confines of 10 furlongs there are meta-corporeal aspects of the horse race never experienced by the spectator. I first knew the horse race as an unfolded experience through the medium of literature. Drawn out in detail were the visceral relationships between horse and jockey, the operations/politics implicit in a racing farm, the strategies and traditions of breeding and training, the excitement of race day morning, and the cognizant thought behind every move during the course of the race. The race compresses into 2 minutes, the life experience of each racer- horse or jockey.

The Drawing: Through drawing, I looked to fold the life narrative of the racer into gesture. Then, as in the race, montage the narrative of different racers. I found inspiration for expressing this agony of entanglement in Picasso’s Guernica. The narrative gesture of war is apparently not unlike that of the horse race.

The process of these drawings was subtractive, many beginning as a coat of black oil bar. The slow drying time of oil bar and linseed oil allowed me the time to carve the horses’ bodies out the blackness. Portions of the drawing were reworked over and over again, conveying motion/time lapse through the multiplicity of elements, such as the doubling of the jockey’s hand in different positions.

There is a dichotomy in horse racing which at once evokes both nobility and grit which I found to exist even at the scale of the horse’s eye, loaded with both the noble courage and animalistic fear. And in the relationship of the fear in horse’s eye to the Jockey’s eye of focused determination. “

As time passed, though, Lauren’s identity was lost to Blackburn Architects. We could make out most of her signature in the lower right hand of the paintings, but was it Lauren Ziker, Zucker, Luker? What had become of the artist who made the art we live with every day? Was she still an artist? A practicing architect? We didn’t know. Finally, John was inspired to track Lauren down through a connection to a colleague who knew her and had kept in touch. And voila! Lauren is indeed still an artist, and an architect, and she was so excited we had tracked her down.

“I have such great memories of Blackburn Architects and of John. I remember being equally disappointed that the timing didn’t work out as the job would have merged my two greatest passions as a life-long horse lover / equestrian and architecture. I am still working in architecture and still enjoy painting and drawing.”

Too Much Water

Rocana
By John Blackburn
One of my favorite sayings regarding water on a farm is, “Certainly not possible in all cases, and not likely in many, but if at all possible, try to ensure the water that leaves your property is as clean as when it came onto the property.”

My experience designing equestrian facilities, a personal interest in issues of sustainability, and my volunteer work with the Equine Land Conservation Resource, have raised my consciousness around land use issues regarding water. How a property drains it, where to find it, how to store it, and so on.

Whether your property suffers from too much or too little, water is an essential requirement for running an equestrian facility and has a significant impact upon the welfare of your horses, the efficiency of your farm and the budget of your operation. Water plays a big part in most Blackburn Architects equestrian projects. I thought I’d address a few solutions we can offer when there’s too much coming onto your property (not your barn – that’s another issue for discussion).

It’s a problem that has come up recently at a farm in Texas, where clients face excessive stormwater runoff on their farm. When the rains started this spring, suddenly excess water poured onto their land from two different counties; displacing basically an entire neighborhood’s volume of stormwater runoff onto their farm.

The team at Blackburn Architects will address this issue by determining the sizes of storages (dams or tanks) and diversions needed. Among the solutions that we’ll apply to divert rainwater off pastures and away from buildings and high-traffic areas in the coming weeks and months are:

Swales or Berms. Berms (elevated earth) and swales (shallow trenches) can act like gutters to redirect water away from areas that
get too much water. Planting grass, trees, and bushes will assist in stabilizing these natural water channels, so they don’t become victims of
flooding over time.

Catch Basins. A catch basin is an underground “reservoir” which collects water and drains it appropriately. Catch basins can
greatly improve farm drainage issues, allowing rainwater to flow through underground pipes leading to a sewer system or holding tanks (where it
naturally disperse). They offer a good method for moving water away from structures and off property, especially if you have to cross roads. At
Wyndham Oaks, in Boyd, MD, a Blackburn designed a system that takes water off the pastures and away from the structures, placing it into a long swale
that runs between paddocks.

Retention Ponds. Retention ponds usually fill as a permanent pool of water, and they can also serve to temporarily detain excess
stormwater. When stormwater enters these ponds, it’s released over a period of a few days, as water levels slowly return to normal.

All these methods of moving excess water can be interconnected. Run-off entering a catch basin flows through a daylight drain to swales located between paddocks. Before it leaves the site, runoff goes into a retention pond, which allows it to evaporate or gradually seep back into the soil, and recycle.

Retrofitting an Existing Barn Roof with Skylights & Vents

Sagamore 5With careful attention to design details, it is possible to retrofit your barn to be healthier for your horses. One important renovation to existing built structures is the addition of skylights and ridge vents to increase light and air flow.

Only a fortunate few horse owners design and build a barn from the ground up. Most buy a property with an existing barn. As the photos illustrate, Blackburn Architects’ client Kevin Plank, the CEO of Under Armour®, bought historic Sagamore Farm in Maryland, and undertook a significant renovation to add light and ventilation to the interior of his historic main barn.

Significant expenditures are not necessary, however. In this discussion, I’m offering simple recommendations for achieving healthier living space for horses starting with an existing barn.

VENTING OPTIONS

For venting an existing barn roof, I suggest one of two options:
1) Add Dutch doors along the barn sides or
2) Add a vent along the bottom edge of the skylight (or ridge if that works best though I prefer the curb vent for better free air access).

Option 1: Add Dutch doors along the barn sides
This option provides good access for ventilation to each stall and a great method of controlling air flow. An owner has the option of leaving just the upper door open to reduce the flow or open both upper and lower doors to give maximum free area. (Of course, in order to open both doors for full access you’ll need to add an interior mesh panel to keep horse in the stall.) If Dutch doors aren’t possible or within the budget, then I recommend adding low wall vents to bring in air low to the floor (which is good for foals and to vent odors caused by ammonia gases near the floor). The vents should be dampered for air control and screened to keep rodents from getting into stalls.

Additionally, Dutch doors provide an abundance of natural light, which reduces the need for electric lighting in the barn and helps purify the stall flooring, reducing the creation of harmful ammonia gases.

Option 2: Add a vent along the bottom edge of the skylight (or ridge)
This option allows for vertical ventilation of the barn using the Bernoulli Principle and the chimney effect. Though the existing barn may not have the best angle for prevailing breezes or roof slope, it will help nevertheless. I also recommend vents at the top of the wall at the roof eave if they can be added. This permits year-round ventilation above the heads of the horses, but still ventilates the barn vertically using the techniques described above.

ADDING SKYLIGHTS

There are a variety of methods and materials that can be used to retrofit skylights into an existing roof. At Sagamore Farm, Blackburn Architects’ design replaced the existing shingles with a new metal roof (not necessary; Sagamore’s roof shingles were worn out and metal was chosen as a better long term material). In more typical circumstances where the existing shingles are salvageable, simply remove the shingles along the ridge and cut out the sheathing or sub roofing material, leaving only the roof rafters.

Continuous curbs should be built along the edge of the opening. Although a continuous skylight or curb is not necessary, I find it aesthetically and functionally preferable. A skylight can then be placed on top of the curbs spanning from one side of the aisle to the other. The curb can and should be vented. The size and amount of free area depends on the barn design, size and location. The skylight width does not have to span the full width of the aisle but somewhere between 8 to 12 feet should be adequate.

The skylight can be either glass (costly and should be safety glass) or some form of polycarbonate. Check your local building codes for requirements. I do not recommend clear glazing. Translucent glazing reduces the visibility of dirt and filters light, which better serves the barn interior. It’s best not to let a strong band of sunlight hit a stalled horse for a long period of time. I also recommend painting the interior of the roof and framing members a light color to improve reflectance.

If a continuous skylight is not possible, then individual roof skylights can be installed over the center aisle. However, if the skylights are not high on the roof and are not vented, they may not do much to increase the barn’s vertical ventilation.

If the barn has a loft it may be possible to remove it, leaving specific structural members spanning across the barn to hold the building together and to provide wind shear strength to the barn. If the loft is used for hay storage (which I don’t recommended for health and safety reasons), then it may be possible to remove a portion of the loft over the aisle leaving the loft in place over the stall for storage or the reverse of that (remove the loft over the stall but leave it in place over the aisle).

While these approaches to increasing light and ventilation in existing structures can work wonders, you should always contact a structural engineer before installation of skylights to determine if the barn can take the modifications needed of if some additional structural work needs to be done.

Do You Need a Site Plan?

IMG_0541Today I got a call from a client who’s buying 120 acres in North Carolina and plans to build a new equestrian center. It’s been years since horses have been on the property. The pastures and paddocks are overgrown. The fences are in disrepair. The property has steeply sloped areas but the client wants a dressage ring. Drainage will be an issue. Together, we’ll figure out a way forward by starting with a Site Plan to map the future; completing the owner’s vision in budgeted stages over several years.

A site plan is completed by studying topography, wind and solar directions, neighborhood easements, height restrictions, zoning restrictions, soils and operational necessities (where are roads, pastures, barns, storage sheds, etc.), There are many benefits to putting together this “roadmap” for future use of the farm property. Consider that there are three major categories of costs when planning to bring horses onto your property: 1. Operational, 2. Environmental, and 3. Infrastructure. Proper planning will save you money in all three areas. Fewer roads, less fencing, better drainage all ensure that the whole farm, not just the horse barn but the entire collection of structures on the site, operates efficiently and safely.

Operational Considerations: First locate where you’ll put the horses – where is your turnout? Where will you store hay, equipment, or vehicles? Do you have access for manure pickup, large-truck deliveries, guests or visitors? Minimizing the number of steps necessary for your daily routine (turnout, stall mucking, etc.) will save labor time, which of course you know is money in the farm biz. Planning will also preserve space for paddocks.

Environmental Considerations: Figure out structure placement within your acreage. It’s important to properly orient any new buildings in the landscape. We design our barns to generate their own ventilation, placing them perpendicular to prevailing summer breezes. (One of many design considerations for maximizing light and ventilation, which is a subject I’ve written about often.) Additionally, placing structures where the land will drain easily makes good sense and will save you and your horses potentially hours of muddy misery or the cost of constantly replacing eroded footing.

Infrastructure Considerations: Fewer roads to maintain means fewer dollars spent.

Creating a master plan does not mean that every part of it needs be built at once. The plan may end up taking years to implement, but as each new structure or paddock is added, it isn’t done in the usual haphazard way. It will save you from asking, “You know, I could use a tractor shed somewhere?” Even those with very limited budgets should consider getting the advice of an expert at the planning stage, given the importance of the optimum farm layout.

Bringing in a professional to carefully plan a site doesn’t mean you need to commit to having a custom barn designed. Blackburn Architects’ guidance can help whether you’re purchasing a kit barn, designing a custom barn, or renovating existing structures. A site plan stands by itself as a service we greatly enjoy delivering to clients across the country.

Considering Building a New Barn? Design Techniques for a Sustainable Equine Facility

Hidden Arches(Originally printed in Equine Wellness magazine, March 2015; newly edited and updated)

I’ve always made it a point to use passive renewable design elements and sustainable materials in my equestrian designs. The motivation is designing for the health and safety of horses, so it’s not surprising that what’s recommended for creating human and eco-friendly structures is also recommended for equines.

Nowadays, Blackburn Architects’ team rarely encounters a client who isn’t enthusiastic about including sustainable design principles in their farm program. With green technologies evolving every day, there are more systems and product choices available to suit the unique demands of equine properties. The most prevalent elements include natural light and ventilation, recycled materials and regionally sensitive natural woods and products.

SUSTAINABLE BUILDING MATERIALS

We incorporate recycled and sustainable materials into the firm’s barn designs. We’ve used recycled rubber bricks and pavers for aisle flooring, and recycled rubber mats for stall floors, and occasionally, stall walls. Not only are these products more comfortable for the horses’ legs and knees, but they also provide a slip-resistant surface. As for building materials, we use everything from FSC (Forest Steward Council) certified lumber and recycled steel to fly ash concrete blocks and recycled wood.

However, we are always mindful of what some recycled material mixtures contain. Some products include substances (plastics, resins, binders, etc.) that could be toxic to horses through off-gassing or if they chew on the material. If you’re designing your own facility, be sure your builder is familiar with the materials ahead of time and is comfortable working with them. Occasionally, we’ve run into a situation where the builder is unfamiliar with a product recommendation and accidentally convinces an unaware owner to use a product that may exhibit these harmful qualities.

BUILDING FOR CLIMATE

It’s important that building materials make sense for both the design and the climate. In more northern locations, we try to design with timber that will provide more insulation for the structure. In the south, a masonry-style building helps keep the structure cool and is more resistant to humidity and insect infestation. While bamboo is an excellent renewable resource option, it’s not often locally sourced and can be costly to ship. Douglas fir and southern yellow pine are the typical go-to lumber products for our firm. They are quality assured, sustainably harvested, and regionally sensitive. When combined with low VOC (Volatile Organic Compounds) finishes and paints, these materials make for sturdy, sustainable buildings that do not sacrifice quality or aesthetics.

WATER MANAGEMENT

Conserving water is imperative to any agricultural property, and there are many top-to-bottom green approaches to consider. It’s crucial to intercept and collect storm water before it becomes ruinous run-off that can affect ground water and nearby ponds and streams. We frequently use porous or “popcorn” asphalt for interior and sometimes exterior floor covering. It’s “self-healing” and aids in water drainage.

Since many horse farms around the country face changing weather extremes (torrential rain and drought come to mind), rainwater collection systems are vital for alleviating the resultant water issues. Roofs can be designed to route storm water into cisterns. The harvested water can then be channeled into irrigation systems for fields, paddocks, arenas and pastures, or collected for controlled distribution to prevent muddy conditions.

ACTIVE RENEWABLE SYSTEMS

In addition to passive systems, I highly recommend including active renewable systems in the design of any horse farm. The beauty of equine and agricultural properties is that they often feature characteristics that compliment these systems. Large swaths of land can facilitate geothermal power systems or wind-powered generators and other equipment. Roofs with large surface areas are common features of many agricultural buildings and make perfect platforms for solar panel systems.

One of the firm’s current projects is an extremely energy efficient property in Missouri. While targeting net-zero energy use, we’ve included a geothermal heating system and solar panels that power infrared heaters in the wash stalls.

Green technologies have come a long way and today’s solar panel systems offer more choices for collecting and storing energy. If designed properly and in the right location, it is often possible to fully rely on the solar panels for all your energy needs. Including these systems in conjunction with natural light and ventilation could conceivably eliminate outside energy dependency for your equine buildings. Over time, solar panels will pay for themselves in savings. Check with your local and state government about tax incentives for incorporating green energy saving systems into your property.

FRESH AIR AND NATURAL LIGHT

Accomplished with steep sun-heated roofs and vented skylights, the combined effects of the Bernoulli Principle (an equation of vertical lift championed by Dutch-Swiss mathematician Daniel Bernoulli) and the chimney effect (air pulled in low and vented up high) circulate fresh air throughout the structure while flooding the space with natural light. This method provides the optimal environment for horses because it turns the typically static barn into a machine while imitating the equine’s natural environment. The process significantly cuts down on the cost and operation of electric lighting and fans and the health and safety risks they can create.

One of the challenges we sometimes encounter with clients is convincing them to include active systems in their design programs. This is usually due to upfront costs. The price impact can be minimized by smart design decisions. Knowing ahead of time what green options are available and which ones you’d like to incorporate will inform your budget early on and, if need be, help you plan the property with future installations in mind.

THE BENEFITS OF COMPOSTING

Composting is another great passive renewable option. We strongly encourage all our clients to include a composting system in their design program. Composting helps manage muck and removes harmful bacteria and other organisms to create natural fertilizer for paddocks. It also helps keep organic material that could produce harmful uncontrolled run-off out of landfills.

Sustainable barn design is about what’s healthiest and safest for your horses. Remember, horses were never meant to be inside. But if they’re going to be, then it’s important to create an environment as close as possible to what they would encounter in nature, using materials and techniques that at the same time don’t harm the very environment they come from.

Celebrate a New Barn in 2020

beechwood aisle_small
Been thinking about a custom barn, or buying property with existing structures that need an extensive overhaul?

I thought I’d take a minute and explain Blackburn Architects’ process for designing a new equestrian facility and overseeing its construction. While not carved in stone, for planning purposes, can easily become a two-year process.

The first step is usually a visit by me or another Blackburn architect. The initial meeting is our first chance to meet, walk the site, look at any existing buildings and discuss the project goals. I’m a firm believer in “a picture is worth a thousand words” but “being there is worth a thousand pictures” Following this, we’ll send a proposal for service, which outlines the process and fees.
Once a contract signed, we get to work immediately.

The timeline usually looks something like this:
• 6 to 10 weeks for Feasibility Study, Site Assessment and Master Plan
• 1 to 2 months for Schematic Design
• 2 to 4 months for Design Development and Construction Drawings
• 1 to 2 months for Permitting
• 12 to 16 months for Construction

At Blackburn Architects, equestrian design starts with the horse and ends with a building that fits the horse, the owner, and the surrounding environment like a glove. It’s as simple and beautiful as that.

Let’s explain the steps in greater detail:

Feasibility Study / Site Assessment / Master Plan
The goal of the Feasibility Study is to determine, as early in the process as possible, whether the intended project fits the owner’s program, the site, and the budget.

We assess any existing building(s) and the site. We take measurements to determine if an in-place structure will work for the goals of the project. We study the land until we come to a clear understanding of wind and solar direction, soils, changes in elevation – all natural and architectural characteristics that guide placement and design of any new buildings. Central to the success of the project, this “Master Plan” addresses all these things and more, providing a road map for the success of all future phases of our work.

The site analysis also includes a review of applicable zoning and easements for the property; we determine what (if any) limitations or restrictions may apply at the property. Land disturbance allowances? Height restrictions? Set-backs?

In tandem with the site evaluation (as soon as we have a contract), we send the client a unique Blackburn Architects questionnaire that we’ve developed over the years. Answers are collected and inform the design; starting off the process with clear direction from the client. It is extensive and though it covers about 25 pages, once it is completed it “paints” a picture of exactly how you would like your farm to operate. The efficiency of the operation is critical and can have a huge impact on your operating cost and maintenance budget.

Schematic Design
Moving seamlessly from the master planning phase (often there is a fuzzy line here where one ends and another starts), we start schematic design. In this step, we help our clients visualize the project design with a variety of techniques using both computer and hand renderings to illustrate the scale and the relationship of the project elements. Ideas, concepts, goals take form at this stage.

Budget Development
Once we’ve worked up outline specifications for the work, we can begin to get a rough idea of the costs. At this point we will either develop a rough estimate based on our 35 years experience with over 300 farm projects, consult with a professional cost estimator or a builder who is familiar with the building type in your location.

Design Development and Construction Documents
Once we have the site layout, design, and budget, drawings and other documents give serious form to interior and exterior finishes, and firmly establish the size, character, and details of the project. These documents will be used by our professional consultants to design the electrical, gas, and other utilities. When these systems are defined, and we have a basic finish schedule and budget, we’re ready to file for the permit and start construct of the building.

Bidding and Construction Administration
With the construction documents complete, we can help clients select a contracting company through a “bidding” process for the work, or we can work with a client’s pre-selected Construction Manager. We work side-by-side with our clients to ensure that the best and most informed decisions are made during this process.

While in my experience this process typically lasts about 18 to 24 months, a lot of this depends on factors that are outside of either our control or our clients. The time of year and weather, for instance, can greatly influence how fast construction progresses, especially in colder climates. Pastures have a growing season, and they need at least a year (maybe two) to establish.

Designing and constructing a custom facility is a very subjective process, which is guided by all kinds of factors including the complexity and size of the structures, the time of year, the strictness of zoning regulations and neighborhood associations, state environmental regulations, and so on. But rather than let these things hold you back, I say, “Jump In” or give us a call to discuss how the process can work for you. When you slide open the doors to your dream facility and see the happy heads of your horses looking over the stall doors, all the time and effort will vanish. At least that’s been my privileged experience over all these years.

Maximizing Ventilation for the Health of the Horse

ventilationWe recently wrote about muck pits and dealing with manure at horse facilities and received comments about stabling time; some saying that shorter times in stalls are better for horses. We completely agree. The longer a horse is stabled indoors, the more likely it is that the animal will be standing in urine-soaked bedding for at least part of the day. And we all know ammonia causes problems.

We want the air inside our barns to be as clean as the air outside the barn. Blackburn Architects’ designs stress aerodynamic ventilation, strategic natural light, and passive solar heating and cooling in our equestrian facilities.

When John Blackburn was beginning to design horse facilities more than 30 years ago, he found combining regionally-appropriate architectural elements with aerodynamic airflow principles created pleasing, healthy spaces for equines and their caregivers. Even early on in his career, heading into his barns was refreshing. “In August,” he has said, “in the dead of summer, when there was no wind – your hair would lift” from the natural ventilation created by the proper placement of the barn on a site, and the use of two engineering principles, which Blackburn Architects has employed in every design then and since:

1. The Bernoulli Principle – As air blows across a surface, e.g. a bird’s wing, it creates lift. Barn placement on a site is critical. If possible, a barn should capture the prevailing summer breezes (for horses you’re always more concerned with cooling rather than warming).

Inside the barn, air needs to move up and out. Blackburn frequently specifies ridge line vents in our designs. The vertical ventilation rids the barn of odors, pathogens and infectious bacteria that could otherwise be transported from horse to horse.

Even in cold climates like Montana, Blackburn Architects designs for maximum ventilation in the winter. “A horse gives off a tremendous amount of humidity; a lot of bacteria and in a contained area – like a stall – that’s an incubator for disease. I don’t care how cold it is where you live, you want to ventilate your barn year-round,” explained John Blackburn.

2. The Chimney Effect – Maximizing natural light in a barn creates a healthy environment by helping to “sterilize” the spaces. For example, as the sun moves across the sky and a band of light travels through a stall – perhaps through the upper portion of an exterior Dutch door left open – it helps to dry and evaporate urine. Blackburn Architects’ spaces have a lot of windows, and skylights. Vented skylights glazed with a translucent polycarbonate panel running the length of the barn are hallmarks of our barns. The light source provides a low cost, shatter-proof feature that diffuses the light, thus eliminating harsh shadows, which could cause horses to spook. “My barns are designed to function throughout the day without the use of artificial lighting, except in enclosed rooms such as bathroom/laundry,” John Blackburn explained.

“A horse is designed to live outside in the wild. If it wants to get out of the sun, it’ll run under a tree. If it wants to get out of the wind, it’ll run behind a hill. This natural, healthy way of living is what we strive to create with our barns so that our athletic partners have the best chance of long, healthy lives – indoors or out.”
