CEU: Thermally efficient building envelopes

Monday, March 23rd, 2015

Visualizing the pathway to low energy buildings

Thermally efficient building envelopes have long been recognized as a necessity for low energy buildings in heating dominated climates. Low energy buildings are not only a goal for buildings built to green rating systems, but are also a stated long-term developmental objective of energy standards that are applicable to all large buildings. Building envelope thermal performance is an increasingly essential consideration as industry is tasked with designing and constructing buildings that consume less energy. This article provides an overview of the resources that are now available to practitioners to help design building envelopes that can be aligned with specific project performance objectives and construction realities.

The occupant factor in low-energy building design

Tuesday, September 23rd, 2014

Occupants’ impact on building energy use continues to increase as building components and systems become more efficient. This source of uncertainty extends well beyond lights and plug loads, often including heating and cooling.

Harnessing the Sun - Solar technologies adapted to the Canadian climate

Friday, October 12th, 2012

Of all the sources of renewable energy available to us, solar energy is arguably the most flexible and least controversial. Solar technology can be deployed at any scale large or small, and can be effective both in rural and urban environments. Although solar panels are often constructed of high embodied energy materials such as steel and glass, the energy they produce over their service life greatly exceeds that required for their manufacture.

Insulation Product Types

Monday, June 14th, 2010

The least expensive and essential first step to saving energy is to increase thermal resistance of the building envelope with insulation. Manufacturers provide a variety of insulation types and applications, each having varying environmental trade-offs.

Commercial glazing systems

Tuesday, March 10th, 2009

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].

by Hugh Perry

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.
