Year-end Progress Report, 2009/2010 Edward MOROFSKY Real Property Branch HQ, Professional & Technical Services PERD TES Year End Meeting Ottawa, May 2010

Output #1 Review Design guidebook (Dec 2009) and identify technologies that are applicable to Canada.

Output #2 See ANNEX 24 Status Report NOV 2009 for a complete description of the work. Work started JAN Professor Handan Tezel of the University of Ottawa is among the participating Experts. The collaboration is well organized and should provide good knowledge for further application of TES in low energy buildings.

Output #3 Identification of technologies and preliminary evaluation for sustainable buildings based on work of Annex 23 for Canadian conditions. See High Performing Buildings, Spring 2009 and the Sustainable Architecture and Building Magazine article entitled "Quebec LEED project hails government direction in sustainability" and this extract from ASHRAE Normand-Maurice Building receives first place in the new institutional buildings category. In 2002, PWGSC ordered construction of a federal multi-occupant building offering offices, classrooms, warehouses, and an indoor firing range for the Royal Canadian Mounted Police, the Canadian Navy and two federal departments. The intent was to create a green building prototype that would be at least 40 % more efficient than the MNECB.

Output #3 continued The building features several innovative measures, including underfloor displacement ventilation for improved ventilation effectiveness, a cascade ventilation principle supplying outside air to occupied spaces before transferring to secondary spaces, radiant slabs for improved thermal comfort and energy efficiency, a geothermal heat exchanger to reduce energy consumption, and an innovative solid thermal energy storage system that reduced first costs of the geothermal heat exchanger. The results show 40 percent more outside air supplied to occupied spaces as compared to ASHRAE Standard ; 51 percent regulated energy cost reduction compared to the 1997 national building code; 600 metric tons in avoided CO2 emissions each year, and 31 percent reduction in potable water use.
