"Energy security, sustainability and efficiency are national security imperatives. This policy supports the Army's global missions in a cost-effective, safe and sustainable manner that will benefit Army soldiers, families and the entire nation," said Hammack.
The new army sustainable design and development principles will follow guidance as detailed in ASHRAE Standard 189.1. The new standard will reduce water and energy consumption, optimize energy efficiencies and performance and reduce negative impacts on the environment, the Army says.
The Army will incorporate such design features as building siting, cool roofs, solar water heating, storm water management and water efficiency. Commissioning, measurement and third part verification are required under the new standard, as is lifecycle cost analyses to promote best practices.
A preliminary analysis by the Army Corps of Engineers indicates that energy savings over current design may be as much as 45% or more, the Army states.
Appointed to her post earlier this year, Hammack is an engineer and founding member of the U.S. Green Building Council (USGBC).
