FVB is assisting the Government of Canada in reducing their greenhouse gas emissions, reducing costs, and increasing the safety and reliability of the federal District Energy systems that provides heating and cooling to more than 80 buildings and approximately 2 million square meters of building space in the National Capital Area. Under the Energy Services Acquisition Program (ESAP), through Public Works and Government Services Canada, the current steam-based system will be converted to a low temperature hot water technology. The ESAP will lower emissions by 60% – equivalent to taking 21,000 cars off the road.

FVB has been involved in the ESAP since 2012.


Our team of engineers compared the Capital and Operations costs of different technologies over the projected 35 year lifespan of the system and recommended a Low Temperature Hot Water system to be the most cost effective, efficient, and versatile when applying alternative energy sources – for example, this system will allow for the use of biomass and/or liquid biofuel as an energy source. Overall, Low Temperature Hot Water systems have characteristically lower GHG emissions, are more efficient, and are safer to operate.


With a reliable plan for the future of the District Energy Systems, FVB has functioned as Owner’s Engineer and Technical support for the call for proposals, the Design Engineer for Building Conversions Designs, the Design Engineer for Tunney’s Pasture, Cliff Street, and NPB CHCP Schematic Designs, and as Owner’s Engineer for a Biomass Thermal Energy Study.
