Acoustics, lighting, ventilation and thermal comfort are the focus of studies at the Indoor Environment Research Facility (IERF), located on the National Research Council campus in Ottawa. A unique facility where both subjective and objective aspects of indoor environmental quality are assessed, the IERF has been the site of groundbreaking research for more than a decade. It has a floor area of 89 m2 and can be configured to simulate a variety of full-scale building interiors.

Originally constructed in 1996, this Institute for Research in Construction (NRC-IRC) facility has been extensively renovated over the last year. Upgrades include:

  • HVAC system: The new ‘state-of-the-art’ system can easily be programmed to control temperature and ventilation conditions.
  • Exterior wall: A new curtain wall system was selected. Operable windows at high and low levels are now an option, to permit the evaluation of natural ventilation.
  • Interior blinds: Two sets of motorized interior roller blinds (opaque and semi-opaque) have been installed. This lets the occupants or the Building Energy Management System (BEMS) control the amount of daylight (and solar gain) entering the space.
