Net Zero Retrofit Planning Process
Step 1 - Contract - The process begins after a contract has been signed. For single unit residential houses the fee is $850.00 CAN for a Net Zero Retrofit (NZR) plan. For other buildings an estimate will be provided. This service is available in Canada and Northern US States.
Step 2 - Site Visit - An engineer, energy advisor or home inspector visits the site building to gather the site component information such as building component size, age & issues (eg. worn out air handling unit, furnace, boiler, lighting, windows).
Step 3 - Energy Analysis - The building's energy usage is modelled to determine the original annual base load. A report that identifies the load mixture by component and fuel is developed and provided.
Step 4 - Lifecycle Analysis – Ages of components are established or estimated and their remaining life is estimated. This step determines the likely date of their replacement which is critical in minimizing replacement costs.
Step 5 - Develop ECMs - Energy Conservation Measures (replacement components) are proposed and analyzed to determine if they can be economically added to the building to reduce energy requirements (eg. a heat pump may be proposed to replace a central air conditioner). These results are summarized in the Upgrade Report.
Step 6 - Reporting - A plan is developed to show how to move your building to Net Zero. This Net Zero Retrofit (NZR) plan identifies the costs for the replacement components, their proposed date of replacement, simple return on investment, payback and the estimated reduced Green House Gas (GHG) production associated with each ECM and site renewable energy generation. See reports below;
Step 7 - Implementation Project Management - In Canada local experienced general contractors can be referred for project implementation. Our service provides the NZR analysis and planning. Consequently decisions are independent of manufacturer or contractor bias. You receive the best advice independent of other influences.
Note - Net Zero also means you have to most likely use renewable fuels (typically solar). This is also a fuel transition plan.
<---- Example House - is located in Ottawa Ontario - pertinent data from the analysis is shown below. This house is currently heated with natural gas.
Example Report
- All 3 reports (below) constitute a BST complete report.
Note - Not all buildings have sufficient solar irradiation to reach Net Zero. Each building must be studied on a case by case basis to determine it's Net Zero potential.
