Canada

Health Canada, a science-based organization, is the Government of Canada’s federal department responsible for maintaining and improving the health of Canadians. As Canadians spend on average 90% of their time indoors, indoor air quality is an important environmental determinant of health.

A literature search was undertaken to assemble and interpretthe-best available· data that can be used for perfonning multizone airflow modelling in mid and high rise apartment buildings. The best currently available data is presented and areas where further field testing research is required are identified. A multizone airflow modelling software tool was used to provide an analysis of ventilation related energy issues in a newly constructed 10 story high-rise apartment building.

This report is a guide to give the canadian builder practical information in the area of energy conservation in new housing. Offers useful suggestions for planning, designing and building a more energy efficient home. Sections covered include energy use in dwellings, air tightness, ventilation andmoisture control, options for improving the building shell, space heating and cooling systems, and cost considerations. Takes the 1979 Ontario Building Code as the basis upon which to develop and evaluate improvements.
