Establishing and implementing aggressive energy performance goals during the design and construction of new commercial buildings is important to achieving those goals over the lifetime of the building. Energy efficiency measures can be applied in various stages of the design and construction process, including scoping and design, procurement, codes and standards compliance, construction and commissioning. Energy savings through these measures can be significant and will have lasting positive impacts on the overall energy use of the building. For example, using technologies and concepts such as radiant heating and cooling, precast concrete insulated panels, and an on-site solar energy system, NREL's Research Support Facility (RSF) is 50 percent more efficient than ASHRAE 90.1 2004 Standards.

The U.S. Department of Energy's Building Technologies Office (BTO) develops resources and tools to help owners, project managers, architects, and engineers design and build highly energy efficient commercial buildings. These programs and tools include the Buildings Performance Database, Energy Modeling Software, and Technology Portal, and the Advanced Energy Design Guide which is meant to help achieve significant energy savings without cumbersome computer modeling or detailed analysis.
