US Department of Energy Buildings Activities

US DOE EE/RE buildings activities are through the Buildings Technology Program (www.eere.energy.gov/buildings)– The program works in partnership with the private sector, state

and local governments, national laboratories, and universities

The Buildings Technology Program has 8 program areas– Appliances & Equipment– Building America– Building Codes– Emerging Technologies– Energy Star– High Performance Buildings– Rebuild America– Zero Energy Building

EE/RE Building Certification- GREEN by Design

The Leadership in Energy and Environmental Design (LEED) Green Building Rating System™ was developed by the US Green Building Councila and is an nationally accepted comprehensive EE/RE building certification program

LEED is a voluntary, consensus-based national rating system for developing high-performance, sustainable buildings

LEED covers new and existing buildings as well as building operation Projects are awarded Certified, Silver, Gold, or Platinum certification

depending on the number of credits they achieve.

The Private Sector is Taking a Leading Role in US Commercial Building EE/RE Implementation

Wal-Mart has set a goal of 100% renewable energy– Largest US commercial energy user– Proposed activities would place approximately 100 MW of PV

on 3,900 stores across five states (RFP’s have been developed)

– Stated goal is to reduce GHG emissions by 20% in 8 years and design a store that will uses 30% less energy

– Wal-Mart opened 100 new stores (many +200,000 sq.ft.) in January 2007

Google has already started construction on a 1.6 MW PV installation that will be the largest single PV instillation in the US– Systems will supply 30% of peak energy needs

Microsoft has an existing 480 kw PV system at its California campus

Oberlin College (Ohio) Environmental Studies Center

The Adam Joseph Lewis Center for Environmental Studies contains over 150 environmental sensors installed throughout the building and landscape

Real time monitors of both energy generation (60 kw) and use are provided

The Center was conceived as an integrated building-landscape system Water use is tracked and treated using a “Living Machine”

US DOE/EERE Solar Decathlon

The Solar Decathlon is a competition in which 20 teams of college and university students compete to design, build, and operate the most attractive, effective, and energy-efficient solar-powered house

The Solar Decathlon takes place every two years with each team displaying its building on National Mall in Washington DC

Financial support is available. For 2007, proposals were issued October 6, 2005 and were due December 2, 2005.

The 2007 Solar Decathlon will be held in the Fall (Oct.-Nov.) 2007 Building are judged on 10 criteria: Architecture, engineering, market

viability, communications, comfort zone, appliances, hot water, lighting, Energy balance, getting around
