This library provides helpers for energy performance of buildings computation.

npm i epb

Get the energy class (like A++, A+, A, B...) following the regulator rules, given the energy consumption.
If the energy class cannot be calculated from the provided data, null is returned.

const consumption = 100
const ecls = await energyClass('brussels', consumption)
// ecls === "C+"

Currently supported:

• brussels
• flanders (exception: energy classes are not used in Flanders)
• france
• wallonia

Get the total consumption of a building in a year, given its energy consumption and its total area.

const consumption = 100
const area = 250
const total = totalConsumption(consumption, area)
// total === 25000
