Start an energy upgrade by understanding your consumption

Planning an energy upgrade starts with understanding where your home’s energy goes today. Reviewing consumption, the building itself, and everyday use helps you choose improvements whose benefits can be assessed for your particular home.

Establish a useful baseline

Gather electricity, heat, and any other heating-energy consumption records over a sufficiently long period. Note changes in household size, indoor temperature, working from home, and activities such as EV charging. The amount of a bill alone mixes changes in consumption with changes in energy prices.

Tell the specialist the size of the building, its heating system, and previous improvements. Ask how weather will be accounted for in the comparison. One unusual year is not a sound basis for promising lasting savings.

Compare improvements using the same assumptions

For each proposal, ask for the upfront cost, estimated effect on energy use, and assumptions behind the calculation. Find out whether it includes maintenance, any new fixed charges, and eventual equipment replacement.

Ask about comfort and the operation of other systems too. Reducing energy use should not depend on making the home less suitable to live in. Adjusting equipment, servicing it, and a larger renovation are different options whose suitability needs to be assessed on site.

Agree on how to track the benefit

Record baseline consumption and the chosen monitoring method before work starts. Afterward, track both energy use and indoor conditions. If household use changes at the same time, include that in the assessment: consumption alone cannot separate the upgrade’s effect from other changes.
