The first step is to assess the overall energy performance of your home by bringing in an energy advisor who will create a report. The results will help you determine where you want to invest. For example, you can fortify your home’s insulation by opting for bio-based or recycled materials, use a renewable energy source for heating, or improve indoor air quality by opting for a specific ventilation system. Note that various financial incentives are available to help you carry out the work.
