October 7, 2011 - The Government of Canada’s Jean Canfield Building in Charlottetown, P.E.I., received its official Leadership in Energy and Environmental Design (LEED) Gold certification, making it the first federal building to receive Gold certification in Atlantic Canada under the category of New Construction or Major Renovations.

The Jean Canfield Building uses natural light to reduce indoor lighting requirements, and has a reflective roof to reduce the amount of heat the building absorbs from the atmosphere. The four-storey, 17,500-sq. m facility was officially opened in 2008, and currently houses about 500 federal employees representing more than 10 federal departments and agencies. It was designed by Bergmark Guimond Hammarlund Jones Architects in joint venture with HOK, and its construction was carried out by Herve Pomerleau Inc.

Some highlights
The building uses radiant chilled/heated slabs, rather than cooling or heating the ventilation air only. Operable windows, and the use of atrium exhaust, allow the building to be naturally ventilated. Energy loss through exhausted air is recovered and reused to assist in cooling/heating new incoming air. Natural and reflective lighting levels, with individual user controls, reduce energy consumption. Daylight harvesting allows for more use of natural light, and occupancy sensors activate lighting only when it is needed. Office bays offer daylight/views on both sides and cross-ventilation to maximize energy savings. The building is further equipped with a roof-mounted photovoltaic array, which will generate 130,000 watts of electrical power.
