Heat conduction or Thermal conduction is the spontaneous transfer of thermal energy through matter, from a region of higher temperature to a region of lower temperature, and hence acts to even out temperature differences.It should be noted that heat can also be transferred by Thermal radiation an...

The Stefan-Boltzmann law states that the total energy radiated per unit surface area of a black body in unit time (known variously as the black-body irradiance, energy flux density, radiant flux, or the emissive power), j*, is directly proportional to the fourth power of the black body's thermody...

Toronto builders could face mandatory green standards by the end of the year. Toronto has had a voluntary standard for a year. To date one highly efficient office building has been constructed and couple more are planned. City of Toronto officials are now looking at all the issues involved in a s...

While US mortgage defaults continue to soar and subprime lenders succumb to years worth of dubious loans, Canada's mortgage market apperas immune to the fallout. It appears Canadian conservativism has insulated us from the excesses of our American cousins.The mortgage market in Canada is healthie...

York and Peel regions are planning to raise development charges - money collected from developers to provide new infrastructure by about 40%.The easy view is that the money is being taken out of the pocket of wealthy developers but the reality is that builders and developers pass this on, so they...

The other big advance in window technology has been the introduction of inert gas fills into the space between glazings. The term inert refers to a class of chemically stable, non-reactive (safe) gases. Argon and krypton are the usual choice, with argon being the most common and cheapest. Filling...

As energy costs continue to rise, the need for more energy efficient homes, offices and buildings has never been more important. Energy efficient windows play a critical role in the overall energy efficiency of a building, and consequently have been greatly improved in this regard.The use of Low ...

Solar radiation affects both energy consumption and performance of the thermal envelope. Solar radiation causes increased cooling loads in summer and reduced heating loads in winter, additional stresses due to thermal expansion of building components exposed to the sun, summer condensation, incre...

Drain surface and roof runoff away from the foundation along the ground surface.Maintain atmospheric pressure in pore spaces in contact with the exterior faces of the basement walls and floor.Prevent capillary water from coming contact with the wall or floor.Prevent water from the soil entering b...

Canada’s ecoENERGY Retrofit ProgramNatural Resources Canada (NRCan) launched the ecoENERGY Retrofit Program on April 1, 2007.  Incentives are targeted to improve energy efficiency in housing, buildings and industrial processes.  The Government of Canada now provides grants to property owners who ...
