Is a Net Zero Home the same as a Zero Energy home?
These days we often hear the term Zero Energy Home, which is confusing and inaccurate unless the home is super energy efficient and disconnected from the grid altogether. What is usually being referred to is a Net Zero Home.
A Net Zero Home is one which uses less, or the same amount of solar energy that it produces. Its main features to be able to achieve this are as follows:
Airtight, super-insulated building envelope – This is usually achieved by insulating the walls, floor and roofing structures with Polyurethane Spray Foam Insulation and using High Performance Windows and Doors, all of which prevent air, moisture and temperatures from entering or escaping from the home.
High-efficiency heating and cooling – Installing a high SEER / HSPF, Variable Speed, Multi-Capacity System together with a leak-free, efficient and Zoned Air Delivery System.
Low cost hot water heating – The most effective being a solar thermal water heater enhanced by an insulated, on-demand, efficient delivery system.
Solar electric system – A photovoltaic system is installed to generate sufficient or more solar electricity than is needed to eliminate the remaining electric load after the above measures have been taken. Included is a bi-directional electric utility meter that allows excess production to be sold to the utility company.
Keeping it simple, that’s what a Net Zero Home means.
