Concrete may be cold and hard, but some energy- efficient builders have been warming to insulating concrete forms (ICFs). As ICFs become more common, home performance professionals need to know how they're built and how well they work
The performance of a heat-pipe heat recovery unit was tested in a two-zone chamber with a horizontal partition. Air velocity was found to have a significant effect on the effectiveness of heat recovery. The effectiveness decreased with increasing air velocity. Simulation of air flow was carried out for the test chamber under natural ventilation conditions. It was shown that a heat-pipe heat exchanger can be used to reclaim exhaust heat in naturally ventilated buildings to effect energy conservation.
Collaboration on energy technology research and development through the International Energy Agency (IEA) contributes to the economic development, energy security and environmental protection objectives of Member countries. The IEA Energy Technology Collaboration Programme provides a framework for experts to work co-operatively and share results. The benefits typically include sharing costs, pooling resources , and avoiding unproductive research paths. Further, participants are able to spread the risks associated with the choice of research priorities .
This study examines a broad range of implications associated with the adoption of the National Energy Code for Housing (NECH) in Ontario. It is based on Public Review Draft 1.0 of the NECH. This study compares the OBC and the NECH providing commentary on key differences between the documents. It examines the energy, environmental and industry implications of adopting the NECH in Ontario. It reviews the cost implications of adoption from a capital, energy and life cycle viewpoint while examining environmental costs by monetizing space heating equipment emissions.
