It is still early in the collection and analysis of energy performance data, but it is already clear that high-performance commercial buildings—some "almost net-zero buildings"—can be constructed cost effectively, providing productive environments for occupants, reducing operating costs, and enhancing the competitiveness of commercial properties.

These are the appendices to the report "Rebuilding Greensburg, Kansas, as a Model Green Community: A Case Study on NREL’s Technical Assistance to Greensburg June 2007 – May 2009".
The new Research Support Facilities (RSF), currently in construction on the campus of the National Renewable Energy Laboratory (NREL), is utilizing a wide variety of energy efficiency measures to reduce energy consumption by 50% over standard commercial buildings. But the goal to achieve a LEED Platinum rating didn’t override a focus on cost. The RSF’s construction costs are competitive with today’s less energy efficient commercial buildings, proof that energy efficiency doesn’t have to come at a premium.
This report considers the major potential for lighting-related energy savings for all major exterior areas, including parking lots, streets and roadways, and building-mounted lighting. Discussion covers safety and security challenges that could hinder maximum energy savings. The report discusses the need for good design features—including appropriate lighting levels—that support safety and security elements, such as visual identification capability and effective lighting for security cameras. Lighting issues related to litigation concerns also are part of this reports.
