Climatic Design LLC has performed a whole-building energy model simulation, a comprehensive energy analysis and an assessment of the building systems and configuration for the Prince George’s African American Museum and Cultural Center (PGAAM-CC). Multiple Energy Conservation Measures (ECMs) were modeled for comparison. The simulation result indicated that with the execution of the recommended ECMs the facility is 18.64% more energy cost efficient than the ASHRAE 90.1- 2004 reference model. This equates to (3) LEED®-NC v2.2 EAc1 points

Following recommended ECMs, which are listed in priority order, are responsible for 18.64% annual energy costs savings of the Proposed Design over the ASHRAE 90.1- 2004 Standard.

1- Internal Lighting Power Density (LPD) reduction – 20% below the standard
2- Selection of more energy efficient fenestration – U-0.29
3- Interior daylighting of all spaces with windows and/or skylights
4- Automatic light controls in all activity areas – Daylight Sensors
5- Additional wall insulation – 3” rigid insulation – R-29
6- Additional roof insulation – 3″ rigid insulation – R-23
