Armory Park Del Sol is a zero-energy community located near the historic downtown area of Tucson. Developed by John Wesley Miller Companies, nearly 90 homes incorporate thermal mass solid concrete block walls, energy-saving appliances and mechanical equipment, high-performance windows, and solar water heating systems. The standard construction methods in Armory Park del Sol already exceed the Model Energy Code by 50%.

In 2007, John Wesley Miller Companies received the AARP/NAHB Livable Communities Award for “a user-friendly home designed with state-of-the-art energy efficient technology, including solar panels and solar water heating systems, to reduce energy usage by 56%.” Governor Janet Napolitano also presented an “Arizona Innovation Award” to John Wesley Miller Companies for the “zero energy homes” in the community.

Civano, a community of 2,600 planned homes in southeast Tucson, adopted the 1998 Sustainable Energy Standard (SES) and updated the code in 2005 for the design and construction of all buildings. The SES identifies beneficial use of solar energy and a maximum use for hot water, cooling, and heating energy as 50% of the local standard as paramount to attaining a high performance level of energy use.

In the 2007 Energy and Water Use in Tucson report, Civano analyzed the energy performance of buildings and homes in meeting codes. Results showed that homes built to the SES are performing better by reducing the heating and cooling consumption by 59% and overall energy consumption by 44% when compared to home built before these codes were adopted. Newer homes, built in Civano by Pulte Homes, are showing 61% savings in heating and cooling and 47% overall energy savings.

The Passive Solar Residence, located in the Community of Civano, is a model for how to design, build, and operate the sustainable desert home. With objectives that include affordability, low energy and water use, indigenous materials, and "smart" operation, the home is demonstrating the key elements of sustainable architecture and community design. The project is led by Rich Michal as part of the Master’s program at the University of Arizona Graduate School of Architecture. Features include integration of vented sunspace into south elevation, 128 ft2 of solar collection through two glass overhead doors, and sunspace thermal mass provided by 4” concrete slab and 24” rammed earth wall. As designed, the home should only cost $133 annually to heat and cool or $0.08/square foot which is 67% less than Sustainable Energy Standard (SES).

The City of Scottsdale, Arizona manages a Green Building Program that encourages a whole-house systems approach through design and building techniques to minimize environmental impacts and reduce the energy consumption of buildings while contributing to the health of its occupants. The program rates building projects based on six environmental areas: (1) site use, (2) energy, (3) indoor air quality, (4) building materials, (5) solid waste, and (6) water. This voluntary program is open to builders in the Scottsdale area and uses a point rating system to qualify projects into the program. Highlighted projects include:

  • Hydrogen House is the highest scoring project in the program. Owner Bryan Beaulieu, a mechanical engineer, worked with the American Hydrogen Association and architect Bob Bacon to design the most sustainable desert home possible. The home has unique building systems to naturally cool the house and produce its own energy. Hydrogen is produced to heat water, for cooking, run electric generators and fuel vehicles. For more information, click here.
     
  • Loloma 5 LLC is a condominium building with five 3-story 1550 ft2 units. The building is designed with minimal impact on site topography and oriented on the lot so the longest side faces south. Features include radiant barrier installed at roof or ceiling, rainwater collection system, zoned HVAC system with individual room temperature control, ductwork insulation, and recycled materials.

Colorado

Aspen Homes has been building homes to a high level of energy efficiency since 2002. They build about 160 homes a year in the Loveland area north of Denver, all of which exceed minimum code-based energy efficiency requirements. The company built an affordable, near-zero energy home in Loveland, CO and the energy performance is available in a Department of Energy report - Performance Evaluations of Prototype House: 50-60% Total Energy Savings. In 2008, they received the EnergyValue Housing Gold Award for the home. The construction costs were listed at $85 per square feet and a HERS rating of 10 (with a 5.85 kW solar electric system).

Other environmental programs offered by Aspen Homes include purchasing wind-power for homeowners in Loveland for one year, guaranteeing homeowners' heating bills won't exceed a certain amount or they pay the difference, and a recycling program that has reduced our landfill contributions by 70 percent.

The Community Office for Resource Efficiency (CORE) is a nonprofit organization that promotes renewable energy, energy efficiency and green building techniques in western Colorado’s Roaring Fork Valley. CORE recently developed two homes in Carbondale that are designed and built to be as energy-efficient as possible and still be affordable as defined by the County. The homes were designed by architect Steve Novy and built by Fenton Construction of Aspen in conjunction with the US Department of Energy’s Building America program.

One home has photovoltaic cells and solar water heating coils on the roof, extra tight construction, and a variety of other energy saving and conserving devices and technologies. One is a “heat recovery process” that uses heat from the stale, warm air exhausted to the outside, to warm the cleaner, fresher air being sucked into the home.

The other has none of the high-tech solar equipment, but is oriented to gain energy from the sun, and is built super-tight to avoid heat loss. NREL is monitoring the energy performance of each home.

Habitat for Humanity in the Denver metro area partnered with NREL to build an affordable Zero Energy Home – a highly efficient home that produces as much energy as it consumes. The design of the 1200 square foot, 3-bedroom Denver zero energy home carefully combines envelope efficiency, efficient equipment, appliances and lighting, passive solar features along with a 4 kW solar electric system to reach the zero energy goal.

NREL has been monitoring the energy performance and released 12 months of data from October 2005 – September 2006. The home was a net producer with the PV system producing 2,347 kWh more electricity than it used. This data confirms this home is the first zero-energy home in the US.

Daniel Buck Construction is owned by Daniel Buck, who has been doing quality solar passive homes for over 25 years. A notable project is a craftsman style home, which is located within the sustainable community of Oshara Village. The company was honored for using off the shelf technology as well as super insulation to achieve substantial energy savings without significantly increasing the cost of the home. It has solar panels for domestic hot water and wired for a future photovoltaic system.

The home achieved the gold level in the Build Green New Mexico program, resulting in a tax rebate of $4.50 per square foot saving over $8,000. Additionally, the home has been third party certified to operate with an annual heating and cooling bill at least 50% below a standard reference home, qualifying it for the federal $2,000 EPACT energy efficient home tax credit.

Oshara Village is a sustainable community in Santa Fe, NM. Local homebuilders are utilized to construct energy efficient homes with consideration to the surrounding environment.

The homebuilders must adhere to the “Oshara Pledge” that requires certain features in each home, including

  • recycled insulation with R-21 in walls and R-50 in ceiling,
  • install 6% of floor space as south-facing glass,
  • use ENERGY STAR appliances and water-saving fixtures,
  • utilize reclaimed water for irrigation,
  • use only programmable thermostats, and
  • use compact fluorescent lighting.

The New Village Institute conducted a study on Energy Savings Possible for American Families Making Sustainable Choices. The study concluded that “an Oshara homeowner choosing normal cost-effective energy conservation features and the required standards would use 51.8% less energy in the home than a typical homeowner.”
