In May 2017, the Canadian Home Builders’ Association (CHBA) officially launched the Net Zero Home Labelling Program, which is focused on building fully energy efficient communities.
Kevin Lee, CEO of CHBA said “The Net Zero Home Label will help to meet the energy efficient housing aspirations of Canadians, and renew Canadian industry leadership in high performance housing. CHBA members have always been leaders and innovators – this program continues that trend.” He went on to say “Our National Home Buyer Preference Study confirmed that consumers want and expect an energy efficient home. Our members have a long history in delivering high performance homes and are ready and eager to deliver the next generation of high performance housing to discerning Canadian home buyers. Our Net Zero Home Labelling Program provides third party confirmation for both the industry and the consumer.”
According to the CMHC web site a Net Zero Home (NZE) is one that is designed and built to reduce household energy needs to a minimum and includes on-site (not all definitions require on-site but CMHC does) renewable energy systems, so that the house may produce as much energy as it consumes on a yearly basis.
According to the CMHC a Net Zero home is not necessarily an “energy autonomous” one. It does not have to be “off-grid” and can be connected to electrical service. This is so that it can supply electricity to the grid when it is producing more than it needs and draw from the grid when household demands exceed the amount of electricity produced on site. The NZE designation is about the net annual consumption of energy being zero. The intention is that over the course of a year, the energy supplied to the grid balances the energy drawn from the grid, therefore giving a net- zero annual energy consumption.
Kevin Lee said that the CHBA is “ showing support for leading-edge innovation in the residential construction industry that with the goal of having those innovations as a voluntary and affordable choice for consumers,” CHBA feels that the Program benefits builders and buyers by clearly defining the two-tier requirements for Net Zero and Net Zero Ready Homes. It also identifies the builders and renovators who provide Net Zero services.
So what do the designation actually mean? Most of us are familiar with the ENERGY STAR designation which indicates that the home is 20% more energy efficient than the Building Code requires. A Net Zero Ready home will have to be up to 80% more efficient than code, and a Net Zero home will be 100% more efficient than code requirements. The reason a Net Zero home is 100% more efficient is because it produces as much energy as it consumes.
Special training has been developed for members of the building and land development industry who are interested in achieving Net Zero. There are CHBA Net Zero Qualified Service organizations, energy advisors, and trainers that will work with builders and renovators to plan their next Net Zero project.
It’s becoming increasingly important to build and market energy efficient homes and communities. The CHBA conducted a nationwide home buyer preference study and discovered that four out of the top 10 ‘must have’ features in a new home were energy efficiency related.
So where in Muskoka can you find a Net Zero home you may ask. Well as far as I can tell nowhere yet! But because Muskoka, by its very nature, attracts people who desire to give more than they take I believe this is something we will be seeing more and more of. Builders like Mattamy Homes and Reid’s Heritage Homes are already offering Net Zero options in their developments. Many more custom builders in our region are taking the required training to be able to offer this option to their clients. So, if you are planning to build a home or cottage in this area ask you architect and builder about Net Zero construction.
