Low Carbon Buildings

A Whole Life Carbon Approach To Building Envelope Design

The need to lower the carbon footprint of buildings is urgent. In Canada this will become a major challenge as impending waves of immigration will require the further development of the built environment, especially buildings and their supporting infrastructure. Recent academic research has revealed there is a need to carefully balance operating carbon and embodied carbon in building design through a Whole Life Carbon perspective. Lowering operational carbon emissions through high-performance building envelopes has numerous benefits: enhanced resilience; improved thermal comfort; lower peak thermal energy demands; less stress on the energy grid; and greater opportunities for cost effective district energy systems and distributed energy resources. But the initial embodied carbon impacts of high-performance building envelopes varies greatly among the currently available enclosure system alternatives. This paper examines the whole life carbon footprint of a number of building envelope systems that are being currently deployed in contemporary building projects. It compares the relative contribution of building envelopes to other significant components of a building's initial embodied carbon content, such as the foundations, structure, and interior finishes. The findings are applicable to both new building enclosures and overcladding retrofits of existing buildings. This paper concludes with a series of recommended strategies for harmonizing operational and embodied carbon in building design with a view towards more environmentally sustainable, lower-impact building enclosures in the Canadian context.
