Levels of Intervention: Low to High
Energy retrofits are going to look different for each era of construction and for the various shapes and sizes of buildings. Newer buildings may require less work, while older buildings may require major retrofit work.
Determining the level of work required for a building will depend on a number of factors:
- The current condition / state of repair of the building in general.
- The age of the building - in general, buildings older than 1980 will need major work.
- Current condition of windows and doors, mechanical systems and indoor air quality.
- Current levels of insulation, as well as the integrity of existing moisture and air barriers.
- Funds available to renovate AND/OR qualification for energy efficiency grants, rebates or loans.
Consulting with an Energy Advisor or a RENOVATION CONTRACTOR can give a homeowner a clearer picture of what their building needs. The Canadian Home Builders' Association Renovators Manual provides excellent information and checklists that describe the types of work that can be expected during a renovation / retrofit.
What kind of work would happen in minor, medium or major energy retrofits? The table below provides examples of the types of jobs, the estimated cost and the professionals who may be involved.
Considerations for Retrofits:
| Level of intervention into the structure | Cost? | Labour? |
|
Minor: Interior jobs
|
Low to mid level | Can be DIY or contractor - low to middle amount of labour. |
|
Mid-Level: Interior and some exterior
|
Mid-level to high |
Contractor, energy advisor Best approach - well planned and noticeable results |
|
Major: Interior and Exterior
|
High level - phased project or all at once, costing spread over years |
General contractor, Energy advisor, Architect, Engineer Most effective results for retrofit aimed at Net Zero, Passive House |
