## Building Technologies Goal

- By 2025, the Building Technologies Program will create technologies and design approaches that enable the construction of net-zero energy buildings at low incremental cost.

**Notes:**
Annex Building at the Social Security Administration 
A complete renovation of this building avoided $25 Million in new construction costs, while recycling and salvaging of materials from the original interior led to 76% of the original building's interior materials being reused. Daylighting and updated lighting led to a 32% reduction in lighting.

## Where our R&D is focused

**Delfield Vantage Line**

**Notes:**
Delfield Vantage Commercial Refrigerator 
Developed in collaboration with DOE and ADL Laboratory.  The Delfield is a 2-door reach in refrigerator that was designed to reduce energy by 50% over the baseline production model.  Turns out it was reduced by 50% with the laboratory prototype, by 66% with the production line model tested at the ADL laboratory, and by 78% when tested by CIEE a contractor in California.  The product exceeds ENEGY STAR standards.   The Delfield is also less expensive to produce than baseline models.

## Impact on U.S. Window Markets (25 years in the Residential market)

- 1973: Typical Window:
- clear, single glazed,
- double or storm window in north,
- Uaverage = .85 BTU/hr-F-sq.ft.
- 2002: Typical Window:
- 95% double glazed
- 50% have a low-E coating
- 30-65% energy savings vs. 1973
- Uaverage = .45 BTU/hr-F-sq.ft.

## Advanced Windows Can Become Energy Producers

## You Can Huff, You Can Puff...But you Can’t Blow this SIP House Down!

**Notes:**
November 10, 2002 - A two-story home located in Portland, Tennessee which managed to stay standing after F2 tornado raved through the city.  The structural insulated panel (SIP) house had been buffeted by F2 tornado winds, that were later confirmed by the National Weather Service to be anywhere between 113–157 miles an hour in the immediate vicinity of the house. The SIP house, built with panels from Allied Foam Products, held strongly together. So strong in fact, that the house stood up to the damaging winds, while the cement block foundation failed. Very little damage could be detected to the house itself.  The homeowners plan to re-build on their Tennessee acreage.  Since their SIP house held personal belongings survived and were well protected from the scattering winds and harsh rains of the storm. Their old appliances, plumbing fixtures,
cabinets, and the like can and will be used in the new house construction. 

## Future HVAC&R Activities

- Develop advanced air conditioning systems such as magnetocaloric
- Determine the viability of a CO2 Refrigerant heat pump
- Develop an HVAC air handler designed for a 50% reduction in electric power required
- Reduce energy losses in air conditioning distribution systems
- Develop 1 to 11⁄2 ton systems with efficiencies over 20 SEER

**Notes:**
Leak-proof duct systems will improve residential heating and air-conditioning by 30%.

- Best Design 2003

**Notes:**
In early May of this year, DOE partnered with the American Lighting Association and the Consortium for Energy Efficiency to announce finalists in Phase I of Lighting for Tomorrow, the National Lighting Fixture Design Competition.  Launched in December 2002, Lighting for Tomorrow invited designs for residential lighting fixtures employing hard-wired, energy-efficient light sources that meet the efficacy requirements of the ENERGY STAR® program. 
A panel of eight judges, including lighting designers, a homebuilder, magazines, a lighting testing laboratory, and lighting showrooms, reviewed 156 paper designs, and selected 11 finalists, including a Best Design of 2003, awarded to Ivalo Lighting Incorporated of Pennsylvania for the "Aliante Pendant" designed by Stefano Casciani.
