Beyond helping builders achieve efficiency exceeding the current energy code, the AEDGs also provide climate-specific recommendations to incorporate today’s off-the-shelf energy efficient building products. These recommendations help designers and builders choose advanced building assemblies, highly efficient heating and cooling systems, and incorporate other energy-saving measures such as daylighting and associated control systems. Additionally, efficiency measures found in the guides can be used in the development of future commercial building energy codes.

The 50% Advanced Energy Design Guide series is being developed through a partnership with the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), American Institute of Architects (AIA), U.S. Green Building Council (USGBC), and Illuminating Engineering Society of North America (IESNA). The Retail Buildings guide is the third installment in the 50% series, and follows the guides for small and medium office buildings and K-12 schools released in 2011. The final 50% savings guide for major commercial building types—large hospitals—is also in progress.

DOE’s Office of Energy Efficiency and Renewable Energy (EERE) invests in clean energy technologies that strengthen the economy, protect the environment, and reduce dependence on foreign oil. Learn more about EERE’s support of building technologies. Additional information on DOE’s efforts to support the development and adoption of building energy codes can be found on the Energy Codes website.

Used more for new construction, Building Integrated PhotoVolaics (BIPV) is slowly gaining ground.  Rather than poking a panel on a pole and sticking it in the dirt where there’s no shade, or racks of panels on the roof, BIPV integrates solar electric, energy efficient design and archetecture:

“…Whenever you approach an industry from a different perspective, that’s when you produce very interesting products, said JD Albert of SRS Energy.  SRS produces curved roofing tiles made of PV that are designed to fit into the mission-style architecture of the southwestern region of the U.S.  Curved red clay roof tiles there are modeled after the Mediterranean roof styles found in Spain and elsewhere. …”

“… There have been many recent developments in air-source heat pumps. The modulating, multistage output rotary compressor design is now available in heat pumps. This design produces high efficiencies for both heating and cooling (HSPF of 10 and SEER of 22). What this means is you can get $2 to $3 worth of heat for each $1 on your utility bills. …”
