Efficient home design, or how to design a home to use less energy

...heating strategies here. A house with 60% of its windows facing south ( passive solar ) may have its heating requirements reduced by as much as 25% for virtually no cost. It is important that it be properly-designed to avoid overheating though, or you will negate any heat savings with air conditioning in the summer. ...

Backyard solar panels
Grants and incentives

The Ontario MicroFIT program and wind projects cannot be built on residential properties but can be built on commercial properties and farmland not deemed residential. 60% of the manufacturing and/or production process for solar projects must be done in Ontario. For a solar project to be considered “rooftop solar” it must be built on an ...

Decentralized Energy Generation for LEED, Passive House & Green Homes
Renewable energy

Which is the Best Type of Home Energy Generation for Green Homes? panels, your own wind turbine, solar heated floors , bike generator , or even a water-wheel! Solar heating - passive & active energy Passive solar heating refers to designing a home to collect heat from the sun . Passive cooling means providing natural shading to cool a home (such as deciduous trees, awnings ...

Passively-heated off-grid LEED Gold home
Off-grid and Net-Zero Housing

Off-grid living blog part 6 - energy modeling projections and real performance

...heating needed for this home is accomplished by sun streaming in the windows. I've taken just enough of a look at the passive solar heating literature to know that this is roughly as high as one should go with passive solar heating in a home unless one is willing to endure unwelcome overheating on warm sunny days in ...

Heat pumps: what they are and how they work

...heating or cooling systems is that a heat pump can actually be configured to do both heating and cooling. The thermodynamic cycle described above can actually be reversed in order to switch it from one function to the other. Instead of taking heat from outside to heat your home on the inside, you can also take heat fro...

Electric Heaters - is heating with electric an eco-friendly option?
Heating with electricity

Heating with electricity

...heating though in new or renovated Green high efficiency homes and when looking for heating zero energy homes , is that as the percentage of electricity generation by renewable sources increases, so does your heating system by default reduce it's carbon footprint. Electric heat sources: Heating with electricity is ...

Air-heated radiant floors

...heating, electrically-heated mats are sometimes installed below the tiles in bathroom floors for added comfort. What you don’t see a lot of, are floors heated with air. Electric wire radiant floor heating © Ecohome How to make air-heated floors work: Since the first forced-air heatin...

Rendering of the Ecohome demonstration house
Efficient home design

Ecohome Demo House: High performance, affordable cost heating Bedrooms, bathrooms and the mechanical room will be concentrated along the north side of the home, with living areas on the open space to the south. This configuration allows the exposed thermal mass of the concrete floor to work effectively with the solar gains from the abundant windows on the south ...

Increased efficiency with heat pumps working in tandem

...heating requirement to about the Passive House standard of 15 kWh per square meter. Windows are a part of that but they are also part of our energy performance strategy. The house is laid out south facing to maximize passive solar heat gain, so we have designed and chosen windows to take best advantage of that. Win...

The best tips for buying windows

...Solar Heat Gain Coefficient, a value between 0 and 1 that indicates how much sun energy passes through the glazing at a 90° angle to the sun rays; a lower SHGC means less solar radiation passing through the glazing and heating the home interior. The Solar Heat Gain coefficient based on orientation in th...

Comparing ground source and air source heat pumps
Heating and cooling

Heat Pumps: Ground source geothermal GSHP or air source ASHP, which one is best for heating a home?

...heating costs by a factor of 3 and offer very attractive paybacks. Research has shown that heating a single family home with a heat pump instead of a natural gas furnace or boiler yields carbon emissions savings comparable to taking an average car off the road . A gradual transition to heating with heat pumps offer...
