...energy-efficiency upgrades, cost $150.00 per sq. ft. to construct. The increase in cost to achieve Passive House energy efficiency over Canadian Building Code energy efficiency was 15%. With similar custom features a code-built house in Fredericton would have cost $130.00 per sq. ft. Operational costs for this Passiv...

...energy-efficiency has a multitude of benefits, with the most notable being that you get a more energy-efficient home that saves you money . An energy-efficient home is a more durable home, a durable home lasts longer, requires less maintenance and has a higher resale value. What homeowner wouldn’t applaud their governm...

...energy. With a conventional boiler: This is a clean burn and it emits very few particles. However, overall efficiency is between 50 and 80%, much lower than a condensing boiler. Both types of boilers are compatible with hydronic heating systems. Gas fireplace: A gas fireplace is an efficient way to heat a home an...

...energy and operating energy If you consider the useful life of a building, about half of its carbon footprint comes from grey energy – or embodied carbon, and the other half comes from operating energy. The grey energy consumed during the construction phase causes a one-off embodied carbon emission: when the building...

...energy-efficiency coordinator for Ecohome. For those wishing to reduce their impact during construction and renovations, it’s worthwhile to consider the embodied energy of products and remember that polyurethane requires an input of 14 times more energy to achieve the same thermal performance as hemp. And at the end ...

...energy efficiency, renewable energy, and green building for more than 35 years, there were countless ideas, materials, and innovative products I wanted to try out. This would be a once-in-a-lifetime opportunity to create a model of sustainability, accessible design (where we can age in place), and resilience. Renovat...

...energy for multifamily projects pursuing PH certification. After the most recent update, the city's building code now recognizes PHPP software (passive house planning package) for energy modelling, meaning builders are no longer required to do a HOT2000 or ASHRAE 90.1 compliant model in addition to the PHPP modelling...

...Energy systems: 5400 w photovoltaic solar panels with battery backup Radiant floor heat powered by a high efficiency gas boiler 84% efficient Zehnder Novus 300 ERV (Energy Recovery Ventilator) While similar in concept, an ERV (Energy Recovery Ventilator) was chosen over an HRV (Heat Recovery Ventilator) , a...

...energy efficiency. Heating a floor increases the temperature differential between the concrete and the ground below it, which increases the rate of heat loss. Contrary to common beliefs, heat does not rise. Warm air rises, but heat goes everywhere. You need only pick up a hot coffee in a ceramic mug to answer this qu...

...energy power storage in an innovative and more affordable manner than we are used to seeing , because they have reversed the customary actions of power generation followed by power storage in big and costly batteries. Instead, Azelio uses photovoltaic (PV) solar energy and converts it into heat in a thermal battery (...

...energy efficiency’ argument. Overall performance of Solariums: The idea that a solarium will heat the interior of the building in winter and reduce its energy consumption unfortunately does not seem to materialize in all but the warmest regions of Canada, like Southern Ontario and perhaps the sunnier regions of coa...
