A summary of recent advances

Glazing considerations such as window area, elevation and orientation, thermal performance and solar shading to optimize natural daylighting and passive solar heat gain are very important to the envelope performance and energy consumption of buildings [1].

Many of Canada’s commercial buildings were built over 40 years ago when there were few, if any, worries about energy performance and environmental responsibility. In an era of cheap and abundant energy, heating and cooling loads were of little concern; buildings were often clad entirely in glass with no differentiation between facades having different orientations.

A sustainable response integrates culture and landscape

View along the rammed earth entry wall, an attractive and durable construction with excellent thermal qualities. Note the section of Cor-ten steel at the location of the service yard.

The design of Nk’Mip Desert Cultural Centre is a specific and sustainable response to the building’s unique context - the unusual Canadian desert found in the South Okanagan Valley in British Columbia. Sited adjacent to a remnant of the Great Basin Desert, of which 1,600 acres are being preserved by the Osoyoos band as a conservation area, this interpretative centre is part of a larger 200-acre master plan.

Product choices and considerations for energy savings

Thermafiber’s Mineral Wool Insulation contains over 80% recycled content and helps projects qualify for LEED Green Building Credits.

Insulation is only one component of many in the building envelope - but arguably the most critical one in determining energy savings and interior thermal comfort. Every aspect of the envelope design must be considered including the air tightness and the positioning of windows within the thickness of the walls. (more…)
