Triangle of Energy Savings: Steps to apply energy savings and alternative energy systems
The Passive House systems uses a collection of systems which are high efficiency and can use
renewable energy as their source of power.
Use sustainable energy systems like passive
solar, heat pumps, balance ventilation.
Balance Ventilation with Heat Recovery:
This is a whole house ventilation system which supplies the home with fresh
air, but the fresh air has been heated with the heat from the exhaust air.
The benefit of this system is that the cold fresh air which is brought into your
home doesn't have to be heated by the heating plant so the size of the
heating plant can be reduced.
With advanced units up to 95% of the heat is recovered! (more)
Photovoltaic panels (solar electricity):
Although not integral to the working of a Passive House,
the use of PV panels can reduce the carbon footprint of a
building. PV's are still very expensive and can increase
the cost of a house by many tens of thousands of dollars.
We usually only include large numbers of PV panels at
the request of a client. (more)
Solar Domestic Hot Water:
Using the sun to produce up to 70% of your yearly hot water
for showering, dish washing, clothes washing, etc. These
systems have been around for thirty years and are tried and
true. Solar orientation of the house is important in placing
these systems. (more)
Air to air heat pump:
An air-to-air heat pump, often called a split, is a highly efficient
way to produce warmth for heating the house or to cover the 30%
of the Domestic Hot Water demand that the Solar Domestic Hot
Water system can't produce.
Though it may be hard to beleve air-to-air heat pumps are
usually 250% efficient! This means that for every kiloWatt of
electricity you put into it, it produces 2.5 kW of heat. The extra
heat it can give us for heating our home comes from the tiny
amounts of heat in the outside air as compared to the boiling
point of the refrigerant it uses. (more)
