On-site Power Generation

EISA 2007 requires Net Zero in new construction and major remodels by 2030.

EISA 2007 requires new buildings and major renovations of Federal buildings to reduce fossil fuel consumption 100 percent by 2030, relative to 2003. As we approach that date, the use of on-site power generation becomes more critical. On-site power generation takes many different forms, from plug-load reduction systems to photovoltaics. The Green Proving Ground program is currently investigating the efficiency and cost effectiveness of four of them.

 

Preliminary Technology Assessments

The Green Proving Ground program, in association with federal laboratories, is currently subjecting the following technologies to real-world measurement and verification in GSA buildings. Preliminary technology assessments are available below as PDFs. Findings from these investigations will be available by 2015.

PV with Solar Water Heating > This “turnkey” system combines normal roof-mounted photovoltaic panels with thermal heat extractor panels mounted beneath them, thereby collecting both electric and thermal energy within the same footprint.

Honeycomb Solar Thermal Collector > A solar thermal collector generates hot water, which can be used for service water heating (SWH), space heating, or process heat. This product employs a ‘honeycomb’ design that promises greater heat gain on the energy-collecting surface and thus higher efficiencies than traditional flat-plate or evacuated tube collectors.

 

The Green Proving Ground program leverages GSA’s real estate portfolio to evaluate innovative sustainable building technologies.
