EnergyValue Housing Award: 2010 Winners by NAHB Research Center

The EnergyValue Housing Award® 2010 Winners publication contains a snapshot of the best practices from those award-winning energy-efficient builders. Now in its 15th year, the EVHA is the nation’s preeminent energyefficiency award honoring builders who voluntarily incorporate energy efficiency into all aspects of new home construction. Builders across the nation submit detailed applications in any of five categories (Affordable, Custom, FactoryBuilt, Multifamily, and Production) in one of three climate regions (Cold, Moderate, Hot). A panel of industry experts evaluates the applications and selects winners based on Energy Value, Design, Construction, Marketing and Customer Relations, and Participation in Energy Programs. Each year the EVHA winners are unveiled at the EVHA Dinner Ceremony held during the International Builders’ Show (IBS) — the world’s largest annual construction tradeshow. The ceremony is a semi-formal affair that includes a presentation about the winners’ building practices, addresses from key industry leaders, and industry networking with EVHA judges, winners, and sponsors. EVHA winners also participate in educational outreach programs during the IBS. The EVHA is funded primarily through the U.S. Department of Energy’s Building America program and the National Renewable Energy Laboratory with additional support from private-sector sponsors.

2010 EVHA Winner Magazine

Introduction The 2010 EVHA builders astounded this year’s judging panel in their delivery of homes that are designed and constructed to exceptional levels of efficiency through careful application of sound building science principles. In addition to representing a diverse set of homes and construction companies, this year’s winning entries include:

 Two net zero-energy homes  An off-grid home  Several affordable homes built by non-profit entities  Innovative luxury homes that push the envelope in their use of advanced technologies  Renewable energy systems on nearly half of the winning homes  Extremely airtight construction, and  An average HERS Index of 41 (including PV energy generation) In addition to employing a systems approach to design, systems selection, and the construction management process, many EVHA builders are also very successfully marketing their products and educating consumers. As consumers’ awareness of the advantages of investing in energy efficiency grows along with the overall upward trend in demand for environmentally superior products, the market is ripe for these awardwinning homes. From snazzy websites and creative consumer brochures, to energy cost guarantees and participation in national training and education programs, EVHA winners are leaders in spreading the facts about building science. EVHA builders realize that, even though they represent the elite of energy-efficient builders, there is always more to learn. They keep up with the latest research and products by participating in national and local programs and conferences and reading internet newsletters. They are serving as an integral part in the dissemination of this knowledge through detailed trade contractor scopes of work, inspection checklists, and trade contractor and real estate agent training. The EVHA winners represent the finest builders of durable, energy-efficient, and comfortable homes in the nation—and they are determined to stay on top. We salute their significant contribution to the home building industry.

Artistic Homes Production builder Artistic Homes employed a “well thought out design process incorporating all members of the team” to build this net-zero energy home at an affordable price point. Energy efficiency and cost effectiveness are central to the builder’s design process. According to the judges, Artistic Homes has a “great approach to integrated design” through which it educates subcontractors, provides oversight throughout the construction process, has a mechanical engineer commission its homes, and seeks out third-party verifications that homes meet the energy-efficiency goals set during the design phase. To quote one EVHA judge, “[Artistic Homes] demonstrates a true commitment to systems engineering and communicates effectively with homebuyers as well as other building professionals.”

Creswell & Company

According to the EVHA judges, “Energy efficiency is clearly very important to this builder - it’s a constant theme in all aspects of the process. From design to construction, there are elements of sustainability. The company only works within a small radius to minimize its carbon footprint, uses a portable solar power generator for construction site electricity, and builds very efficient houses.” This house, with a HERS Index of 25, demonstrates “solid performance.” Yet the builder is clearly committed to ongoing education or improving the performance of future homes. The company also did an “admirable job” of maintaining and taking advantage of the site’s natural features, especially in keeping existing trees for shading.

Ferrier Custom Homes

As a custom builder, Ferrier Custom Homes could be content to focus on superior efficiency and put marketing efforts on a back burner. After all, they are sought out by prospective clients because of their reputation for high-performance homes. Instead, according to the EVHA judges, “Ferrier demonstrates a good understanding of what it takes to build appropriately in a hot climate, and does an exceptional job getting the word out to the public about the benefits of energy-efficient home building.” The homeowner’s manual for this custom home was noted as “one of the most professional” that one EVHA judge had ever seen. The judges noted, “Ferrier Custom Homes has truly systematized the whole idea of green building.”

Habitat for Humanity Portland MetroEast Energy is a clear priority for this affordable builder that “did a great job of working within their substantial constraints,” as one EVHA judge noted. The judges were impressed with this organization’s creativity in maximizing daylighting and passive solar heat gain. “They had a wrongly oriented lot and cut it into two rightly oriented lots! The passive solar and daylighting elements were very well integrated.” The judges found the submittal to be “excellent across the board.” Not only was the home technically sound, but the builder demonstrated superior marketing and customer relations. The unique nature of the project—built with a volunteer labor force as part of the Habitat for Humanity business model—helped the project garner significant local press coverage where energy efficiency was always the centerpiece.

Nelson Construction, Inc. Nelson Construction had a “great deal of focus on the value of energy efficiency before, during, and after the sale of the home.” This focus started by optimizing the efficiency of a traditional production home design through solar orientation and a systematic design process—and continued by applying this optimization to the entire neighborhood of 10 homes. “The company demonstrated a very strong commitment to energy efficiency,” the EVHA judges said. “They had an excellent outline of criteria and they clearly demonstrated how those criteria informed the design and selection of materials.” Careful parametric analyses performed during the design phase resulted in only a very small increase in sales price—3% excluding PV—due to the home’s efficiency features.

Sierra Homes Working for homeowners who placed energy efficiency at the top of their goals and were willing to adapt to living “without instant mechanical remedies” gave Sierra Homes and its architect the freedom to design a unique passive solar, off-grid home that includes no mechanical cooling system and uses only a wood stove for heating. According to the EVHA judges, “This project truly represents thought leadership and the benefits of what happens when the client, architect, and builder collaborate well. Sierra Homes clearly demonstrates a commitment to responsible building … and a personal commitment to building science that is truly unusual.”

Yavapai College Residential Building Technology Program EVHA judges were in awe of Yavapai College Residential Building Technology Program’s submittal that went “above and beyond in almost every aspect of design and construction.” By taking the utmost care with construction details—which are extensively inspected with multiple checklists throughout the construction process—the home achieved an exceptionally low air leakage rate. The program starts from the beginning with “very good site and building design in accordance with the site conditions” that includes considerable energy analyses conducted by students as a learning tool. “They even chose different glazing for the south-facing windows … a great design element,” proclaimed one judge. The school not only uses the design and construction process for its students’ education, but its work goes beyond the classroom as it conducts extensive outreach to the community.

Yavapai College Residential Building Technology Program The judges’ decision to name Yavapai College’s Residential Building Technology Program the 2010 EVHA Builder of the Year is historic in that it’s the first time a “non-traditional” builder has won the award in its 15-year history. But, despite the novelty of the recipient, the award was not altogether unexpected. Yavapai’s team has earned gold awards for each of the five applications submitted to the EVHA program. The school’s 2010 entry is the latest example of excellence when it comes to building an extremely energy-efficient home. One of the elements judges take into consideration when choosing the Builder of the Year is what the builder does within the industry to promote energy efficiency to both the building community and the public. According to one judge, “Yavapai is significant in their influence on the industry. These are people who are going to be out working on the jobsite” and they will be taking everything they learn with them. Another judge, citing the program’s “track record of excellence,” said, “it’s time to say that this is one of the best educational programs in the country.” Yavapai’s program has been under the direction of Tony Grahame for the past 14 years, during which time an estimated 2,100 students have learned about designing and constructing highquality homes. Following the changing climate of the construction industry and its workforce, Grahame has adapted the program to meet the needs of the industry by focusing on green building and energy efficiency. This has made the Yavapai Residential Building Technology Program the first community college program to receive recognition for building excellence from major industry organizations such as the National Association of Home Builders (NAHB) and DOE and the NAHB Research Center through the EnergyValue Housing Awards program. In 2008, the United States Green Building Council (USGBC) also named Yavapai the recipient of the Excellence in Green Building Curriculum Recognition Award. Stained concrete entry 22

Outreach is a major focus of the Yavapai program. By hosting an open house after the completion of this latest award-winning project, Yavapai’s students were able to share what they had learned about the latest research, products, and technology with the community and local building association members. Customer service even took a unique twist with this Habitat for Humanity house when the homeowner enrolled in the school’s Residential Technology I and II programs to learn about the technology in her house. Yavapai’s students aren’t simply learning to how to build high-performance, energy-efficient houses; they are also learning how to design the houses properly, choose the most appropriate materials, apply the latest building science principles to the process, and put everything together right. Their 2010 winning home was described by the judges as “so excellent that they would have gotten gold in any category.”

As an active participant in the local green building community, the company conducts seminars for local real estate professionals and other builders and provides extensive training for its subcontractors. Its techniques have become so well known that their HVAC and solar thermal contractors get requests for a “Chandler-style” system. To maintain control over HVAC design, the company uses an independent engineer to design HVAC systems rather than relying on the HVAC contractor. As the EVHA judges put it, “[Chandler Design-Build] nicely integrates systems and builds to a higher standard.”

The Pepper Viner High-Performance Home Enhanced with BASF Chemistry is 80% more energy efficient than an average American home, reduces environmental impact and is built to last for decades. BASF / Pepper Viner High-Performance Home Systems

BASF / Pepper Viner HighPerformance Home Launched Offers production builders a map for 81% increased energy efficiency By Jack Armstrong BASF, the world’s largest chemical company and Pepper Viner Homes present the Pepper Viner/BASF High-Performance Home—a model for near-zero energy construction for production builders nationally. Located in the Tucson, Arizona’s Civano North Ridge community, the test home, which is 81 percent more energy efficient than a typical home, is currently open for public tours and featured on www.betterhomebetterplanet.com. But according to Jack Armstrong, Leader of Building and Construction Markets in North America for BASF, creating a repeatable and profitable model for mainstream builders is the real success story. “When BASF built the award-winning, LEED Platinum Near-Zero Energy Home in 2005, we asked ourselves, what would it take to make this kind of high-performance home mainstream?”

said Armstrong. “Working with the Pepper Viner team allowed us to create a repeatable process that will make their business more competitive and provide a road map for other mainstream builders as well.” BASF worked closely with the Pepper Viner team and their sub contractors to expand their competencies in the areas of product and system installation, knowledge and procurement as well as quality assurance. The test home achieved a remarkable rating of 19 out of 150 on the U.S. Department of Energy’s EnergySmart Home Scale®, making it close to being a net-zero energy home. It is also anticipated that it will achieve a Platinum score home from the U.S. Green Building Council’s LEED® rating system and was already awarded the Pima County certification system’s top (emerald) rating. Moreover, the Pepper Viner team is using what they have learned about integrating high-performance systems and products on other projects. According to Bill Viner, President of Pepper Viner Homes, “Now, we are able to take what we’ve learned from our collaboration with BASF and extend even more value to our customers. For example, we will be able to include many of the energy savings in our Sunnyside Pointe project in Tucson, Arizona, an affordable housing initiative slated to start construction next month, and in the La Posada retirement homes we are planning to build in Green Valley, Nevada in early 2010.” For more information about the Pepper Viner/ BASF High-Performance Home, please visit www.betterhomebetterplanet.com.

Glossary Air Changes per Hour (ACH) Measurement of the air leakage rate of a building, specifically, the number of times each hour the total volume of air in a building is replaced by outdoor air. Typically expressed as a rate experienced under normal, atmospheric pressures or under some higher test pressure.

Annual Fuel Utilization Efficiency (AFUE)

Seasonal efficiency of a gas-fired furnace or boiler. Takes into account cyclic operation. The higher the number, the more efficient the heating equipment.

Backdrafting Potentially hazardous

Energy Efficiency Mortgage (EEM) EEMs

recognize that the monthly energy bill savings from improved energy efficiency can more than offset the increased monthly mortgage cost attributed to energy-efficiency upgrades. Some products allow a higher loan-to-income or debt-toincome ratio while other newer, more innovative products finance 100 percent of all cost-effective, energyefficiency upgrades in the mortgage, thereby eliminating any increased downpayment and requalification requirements.

Energy Efficiency Ratio (EER)

condition in which the exhaust from combustion appliances does not properly exit the building. This can be due to a number of factors including a blocked flue or a pressure difference within the home.

Instantaneous efficiency of air conditioners measured at standard test conditions. The amount of cooling provided per unit of electricity purchased. The higher the EER, the more efficient the air conditioner.

Blower Door A large fan placed in an exterior doorway to pressurize or depressurize a building to determine its air leakage rate expressed in air changes per hour or cubic feet per minute.

Energy Factor (EF) Overall efficiency of

Building America Program Building America Program is a private/public partnership sponsored by the U.S. Department of Energy that conducts research to find energy-efficient solutions for new and existing housing that can be implemented on a production basis. The program uses a systems engineering approach to home building and unites segments of the building industry that traditionally work independently of one another.

ENERGY STAR Home ENERGY STAR

California Corner An Optimum Value Engineering technique that uses two studs (instead of the usual three or four) to make an exterior corner. The result is better insulation and use of fewer resources, in addition to cost savings. Several variations are possible. Coefficient of Performance (COP)

Measurement of the steady-state performance of electrically operated systems, including ground-source heat pumps. It is the ratio of useful energy output to purchased-energy input. Can also refer to gas-fired systems.

Combination System Heating system that uses the domestic water heater for both water and space heating. Hot water is typically piped to a heat exchanger (coil), where a fan blows air over the coil to produce heated air. Condensing Furnace or Boiler High-

efficiency systems that extract such a high percentage of the available energy from gas combustion that the water vapor in the burned gas (combustion products) condenses to liquid water before leaving the furnace.

Conditioned Space Area within a

house that is heated and/or cooled. Conditioned space is separated from unconditioned space by a thermal envelope.

Desuperheater Device that takes waste heat extracted by heat pumps or air conditioners and uses it to heat domestic hot water.

2010 EVHA Winner Magazine

a water heater or other appliance. The amount of hot water produced per unit of gas or electricity purchased. The higher the energy factor number, the more efficient the water heater. qualified homes must achieve a minimum HERS Index score of 85 in climate zones 1–5, and 80 in climate zones 6–8. The ENERGY STAR Home Program is a program of the U.S. Environmental Protection Agency and the U.S. Department of Energy.

Envelope (Thermal or Building Envelope)

The protective shell of a building that separates the inside environment from the outside environment; includes both an insulation layer and an air infiltration layer.

Flex-Duct Flexible ductwork made with

an inner liner, a layer of insulation, and an outer covering of plastic.

Frost-Protected Shallow Foundation (FPSF) Foundation system in which

foam insulation is placed around the perimeter of a foundation to reduce heat loss through the slab and/or below-grade walls, subsequently raising the frost depth of a building and allowing foundations to be as shallow as 16 inches below grade.

Geothermal System A heat pump that

uses the ground or water as a heat source or sink. Efficiency is improved over air source heat pumps as the temperature of the ground or water is more constant and moderate than that of the air. Geothermal systems typically incorporate some method to contribute heat to the domestic hot water system.

Heat Pump Similar to an air conditioner

but can operate in reverse to heat as well as cool. Transfers heat (usually from the air) from one location to another.

Heating Seasonal Performance Factor (HSPF) Efficiency of a heat pump in

the heating mode, taking cycling into account; the amount of heating provided per unit of electricity purchased. The higher the HSPF number, the more efficient the heat pump.

High Efficiency Particle Accumulator (HEPA)

An air filter that captures a high percent of all particles, including very small particles not captured by other types of filters.

Home Energy Rating System (HERS)

Index HERS Index is a scoring system established by the Residential Energy Services Network (RESNET) in which a home built to the specifications of the HERS Reference Home (based on the 2006 International Energy Conservation Code) scores a HERS Index of 100, while a net zero energy home scores a HERS Index of 0. The lower a home’s HERS Index, the more energy efficient it is in comparison to the HERS Reference Home. Each 1 point decrease in the HERS Index corresponds to a 1% reduction in energy consumption compared to the HERS Reference Home.

Insulating Concrete Form (ICF) Concrete form-wall constructed of foam insulation that remains in place after the concrete cures. International Energy Conservation Code (IECC) A building code that addresses

the minimum requirements of an energy-efficient building design including efficiency details for building envelopes, mechanical equipment, lighting, and appliances. Minimum requirements may be met using prescriptive and performance-related compliance paths. Provisions of the IECC are generally adopted, sometimes with modifications, by a local jurisdiction or on a state level.

Low-Emittance (Low-E) Glass Low-e

glass has a thin, invisible coating that reduces the flow of radiant heat through windows. The most common coating reduces solar heat gain and increases resistance to radiant heat loss through windows.

Low-E2 Glass Also called solar control

glass, is a good glass for hot climates because, in addition to improving the insulating ability of windows, it also limits solar heat gain by blocking passage of infrared and some ultraviolet rays. Solar control glass allows a higher level of visible light to pass through a window with less solar heat gain reduction than tinted window coatings.

Manual D Method developed by the Air

Conditioning Contractors of America to design residential duct systems.

Manual J Method developed by the Air Conditioning Contractors of America to calculate residential heating and cooling loads.

Manual S Method developed by the Air Conditioning Contractors of America to select and size heating and cooling equipment to meet Manual J loads based on local climate and ambient conditions at the building site.

Mass Effect Describes the effect of

a high-mass material on heating or cooling requirements. High mass materials such as concrete, used in floors and/or walls, can absorb and store significant amounts of thermal energy, which is later released. In some climates (those with lots of sunshine, low humidity, and large daily temperature fluctuations), high-mass materials can mean a reduction in cooling and heating requirements by delaying the time at which the energy is released into the house.

Mastic Strong, flexible material, which

has a thick, creamy consistency when applied, used to seal ductwork. Also used to describe a type of ceramic tile adhesive.

National Green Building Standard (ICC 700-2008) The first residential green

building rating system to undergo the full consensus process and receive American National Standards Institute approval. The four threshold levels - Bronze, Silver, Gold, and Emerald allow builders to achieve entry-level green building, or the highest level of sustainable residential building incorporating energy savings of 60% or more. Single-family and multi-unit homes, residential remodeling projects, and site developments are all covered in the Standard.

Optimum Value Engineering (OVE)

Sometimes referred to as Advanced Framing, OVE framing techniques use less lumber and therefore improve a structure’s level of insulation. Techniques include 24-inch on center stud layout, single top plates, engineered header sizes, and special corner and wall intersection configurations.

R-Value Measure of the resistance of a

material to heat flow. The higher the number, the greater is the resistance to heat flow.

Radiant Barrier A material that reflects radiant heat, typically a foil-faced or foil-like material used in roof systems. Used properly in some climates, it can reduce cooling requirements but has no positive effect on heating requirements. Sealed Combustion Furnace Furnaces or boilers that draw air for combustion from outside the home directly into the burner compartment and vent exhaust gases directly to the outside. The systems eliminate the risk of backdrafting. Seasonal Energy Efficiency Ratio (SEER)

The amount of cooling provided by a central air conditioner per unit of electricity purchased; SEER is tested over the entire cooling season, taking cycling into account. The higher the SEER number, the more efficient the air conditioner. SEER, in contrast to EER and COP, takes into account the efficiency losses resulting from system cycling.

Sizing Calculation of the heat loss and heat gain for a building at

“design temperatures” (those close to the maximum and minimum temperatures anticipated for a given location) in order to select heating and cooling equipment of sufficient capacity. Installing excess equipment capacity, or oversizing, is common but leads to inefficient operation and, for air conditioners, decreases the dehumidification. Calculations are most often done according to the ACCA Manual-J (or similar) procedure.

Solar Heat Gain Coefficient (SHGC)

An indicator of the amount of solar radiation admitted through and absorbed by a window and subsequently released as heat indoors. SHGC is expressed as a number between 0 and 1—the higher the number, the more solar heat the window transmits.

Structural Insulated Panel (SIP) Loadbearing wall, roof, or floor panel made of foam sandwiched between two sheets of plywood or oriented strand board (OSB). Unconditioned Space Area within the outermost shell of a house that is not heated or cooled—the area outside of the thermal envelope. Such areas typically include crawlspaces, attics, and garages. U-Value Measurement of the thermal conductivity of a material, or inverse of R-value. The lower the U-value, the greater resistance to heat flow (lower U-value = higher R-value).

Judges 2010 EVHA applications were reviewed by a 10-member judging panel comprised of new and returning judges who have extensive experience in the fields of engineering, construction, design, and marketing. Applications are grouped and up to eight applications are assigned to two judges who then complete independent reviews of each submission. During this initial phase, judges record comments and questions for each application and home; these become part of the report that is submitted to all applicants after final judging. The EVHA judges’ feedback that applicants receive is the most beneficial part of the application review process giving each participant unequalled access to the judges’ expertise. Serving as an EVHA judge requires a major commitment of time and resources. Initial review of each EVHA application usually takes a minimum of 3-5 hours and may involve research of material data specification, building code requirements, and other industry guidelines. After completing the preliminary evaluations, judges travel to the NAHB Research Center for a full day of final judging. EVHA judges also volunteer their time and knowledge through speaking engagements at EVHA workshops and educational sessions. A special thank you is extended to the 2010 judges for their willingness to share their expertise with our applicants and their dedication to advancing energy efficiency through the EVHA.

Retrofit Category In response to the increased interest in and focus on improving the energy-efficiency of existing homes, the 2011 EnergyValue Housing Award competition introduces the EVHA Retrofit Category. Designed to recognize builders and remodelers who successfully integrate significant energy-efficiency improvements into home retrofit projects, the judging criteria will focus on the same criteria as the EVHA New Home categories: application completeness; energy value; design; construction; marketing and customer relations; and energy program participation. Similarly, the entries will be grouped according to climate: hot, moderate, or cold. For this competition, Retrofit is defined as an existing residence that has been significantly retrofitted, remodeled, or renovated with specific focus on energy such as energy upgrades or energy improvements. Â Applications in the Retrofit Category will be required to include details about the existing home prior to and after renovations, including changes in the structure, mechanical, plumbing, and electrical systems. In addition, a discussion about why and how the renovations were made highlighting the energy upgrades and improvements as well as test data and/or inspection reports generated prior to and after renovations should also be submitted for consideration. Retrofit Category judges will base their evaluation of each entry on overall energy performance improvements; integration of energy considerations into the design; product selection; and innovations used throughout the retrofit, remodel, or renovation to achieve greater energy savings. Through educational programs and national media coverage, the Department of Energy and the NAHB Research Center anticipate that this new award category will promote an increased awareness of the value of energy efficiency improvements in existing homes among building professionals, homeowners, and others. Because of the significant differences between new home construction and remodeling, a separate application has been created for the Retrofit Category to include variations in information necessary to evaluate existing homes.
