The federal government says it’s preparing to spend up to $5 million on a pilot project aimed at reducing the environmental footprint of an office building and data centre at the Confederation Heights complex.

Specifically, the project involves switching from high-temperature hot water to low-temperature hot water for space heating, humidification and domestic hot water at the National Revenue Headquarters Building and Data Centre, located at 875 Heron Rd., near Bronson Avenue.

The property is currently supplied with high-temperature hot water for heating from a central heating and cooling plant, said Jean-François Létourneau, a spokesperson for Public Services and Procurement Canada.

Earlier this month, the federal government published a procurement notice to install energy transfer stations, which would allow the building to be operated with water that’s less than 100 degrees, down from the current 145 degrees.

This also requires renovations to the building’s heating ventilation and air conditioning system, as well as the domestic hot water system.

The project is estimated to cost between $1 million and $5 million, according to the government procurement notice.

“This project will provide valuable lessons as we ... modernize the district energy systems that heat and cool more than 80 buildings in Ottawa,” said Mr. Létourneau.

The federal government set a goal in last year’s budget to reduce greenhouse gas emissions related to buildings in the National Capital Region by 45 per cent. Such a move would bring both environmental benefits as well as lower operating costs.
