Efficient home design

Ecohome's Demonstration House will be used as a vehicle to launch a free online building guide series detailing best practices for high performance, cold climate home construction. The guiding principles during the design of Ecohome’s demonstration home: Passive heating and cooling, healthy living space, affordable to…

When Having a Home Built, Making better choices in design & materials is a Wise choice. Even if unconvinced about climate change, Green homes are proven to last longer, are healthier, cheaper to run & Worth More - Total Win. As the effects of climate change become more pronounced every year, it is becoming virtually i…

Intelligent home devices allow you to control your home remotely, and send you notices of problems. So what is a smart home? When paired with intelligent and connected home devices, the phones that most of us carry in our pockets can make our homes safer, more comfortable and durable, and reduce our home energy consum…

Dense materials hold more heat than light fluffy stuff does. This can work for or against you. Materials in a home that act as thermal mass are things like concrete, masonry, ceramic tiles, even a large volume of wood like timber frames. Intentionally adding greater amounts of thermal mass in a building can be an adva…

When a substance melts or solidifies, it absorbs or releases energy. Materials that do that at room temperature can help regulate temperatures in homes.   This article was inspired by a podcast I heard at Positive Energy, where I have yet to hear a podcast that I didn't want to listen to a second time, so check them o…

Just as a regular battery stores electrical energy, a thermal battery stores heat. Solar heat can be collected, stored and distributed later as needed. What is a thermal battery? Thermal mass of any kind can by definition be called a thermal battery, as it has the ability to store heat. In the context of a house, that…

Homes are often over-insulated in some parts and relatively under-insulated others. Balanced insulation when building a Green Home means applying your insulation dollars where they are most needed. Home Insulation, How Much do I need & Where? Think of the heat in your home as if it were water behind a dam, and that in…

Better houses can be cheaper to live in from day one. Why build a less comfortable, and less efficient home if it actually costs more. There are probably only two general desires we share when imagining a dream house - we all want the nicest one possible for the least amount of money. And we want both of those things…

Study shows there are more factors at play beyond simply the R value of materials in determining the thermal performance of buildings. First published in ecoHouse Canada The thermal performance of wall assemblies and insulation products has long been characterized using R-value, a metric which describes thermal resist…

A case study by Alex Wilson of the Resilient Design Institute on Ecohome's Kenogami House in Northern Quebec. A resilient home for Sustainability Northern Quebec isn’t a place where one might expect to look for a model of resilience. It’s bone-chilling cold in the winter with 10,450 heating degree days per year (Fahre…

Thermal bridges in walls can reduce the overall performance of a home. Thermal breaks are the answer to this problem. It is easy to look at the R value rating of a material and assume that our entire wall assembly matches it uniformly. But when you factor in the thermal bridges caused by framing materials and any disc…
