Methodology

Transparent calculation

BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.

Delivered heat = current energy × current efficiency. Proposed energy = delivered heat ÷ proposed efficiency. Annual savings = avoided energy cost + maintenance savings.

FAQ

Heating Energy Savings Calculator questions

Can different heating fuels be compared?+

Yes only after converting both to a consistent energy-equivalent basis and using the correct delivered-efficiency assumptions.

Is simple payback the same as return on investment?+

No. Simple payback ignores financing, discount rates, equipment life and future energy-price changes.

Why can real savings differ?+

Weather, thermostat settings, distribution losses, occupancy and equipment controls affect actual use.
