The US Department of Veterans Affairs (VA) has finalized the design build of CHP systems for two medial centres in the Texan cities of Houston and Dallas.

Spaw Glass Construction was awarded a US$31 million contract for the Houston project and McCarthy Building Companies was awarded $23 million for the Dallas project.

VA has been rolling out a programme of CHP in new hospital constructions across the US since last year.

VA currently has operational CHP systems at North Chicago VA Medical Center, Jesse Brown VA Medical Center (IL), San Diego VA Medical Center (CA), and a CHP at Mountain Home VA Medical Center (TN) that is powered by landfill gas

In addition, VA has plans for CHP systems fuelled by renewable resources at a further nine medical centres that are currently in the design phase.

VA says it has performed renewable energy studies to determine which facilities would be most ideal for investing in renewable energy technologies based on availability of renewable fuels, energy plant characteristics, and local utility rates.

VA says its short-term goal is to increase its renewable energy consumption to 15% by 2013.
