What’s that? Insulation is for all seasons?

It’s a beautiful Friday morning and I am preparing for a few meetings here at the head office in Woodstock. We are over half way through the winter of 2010/11 and I am already thinking of spring. We will very shortly finish the renovations to the office here, and to our new location in Milton. What a beautiful facility that will be for all of our customers in the GTA. The new facility will be open to the public mid March. Continue reading

How weatherization affects homes

In Southern Ontario, we know that the weather can be very unpredictable, in a single day we can experience the affects of hail, snow and rain. Depending on the season temperatures can range between -30 and +30ºC. Homes in Ontario for this reason need to be properly weatherized, so that they can be protected from the elements. The most important aspect of weatherization is heat, and for home builders the challenge is to keep heat in during the winter, and out in the summer. Continue reading

House as a System

Think of your house as a composition of various different components that work together to form a single interdependent system. Heating, cooling, and ventilation components, along with the construction materials and people that live in the house all interact to form this interdependent system. Changes made to one component of a house can affect other components.

For instance, if your house is cold or drafty it is recommended that you eliminate air leaks from the buildings envelope before investing in a high efficiency furnace. Otherwise, the furnace will be constantly running just to maintain a comfortable temperature level.

New high-efficiency windows won’t prevent condensation problems if they are improperly sealed or insulated, the humidifier on the furnace has not been adjusted or if kitchen and bathroom exhaust fans are rarely used or are improperly ventilated.

A properly functioning home incorporates air tightness and good ventilation. Have an NRCan certified energy advisor test your houses’ system for energy efficiency. Any recommendations made will always consider the “house as a system” concept.

Building Science 101

Long gone are the days of constructing a building using any available materials and giving little or no thought to how the different materials interact with each other or the physical environment. Nowadays there’s a real scientific process behind building material selection, design, construction, and maintenance. Regional climate and weather phenomena are also taken into consideration in the design and construction of modern buildings. This new approach is what’s known as ‘Building Science’. Continue reading
