Energy Efficiency Calculator

Calculate energy efficiency

The Energy Efficiency Calculator is an essential tool designed to help homeowners and real estate professionals evaluate the energy performance of residential properties. By entering basic information such as square footage, energy usage, and utility costs, users can obtain a detailed breakdown of their energy efficiency. The calculator uses industry-standard metrics to provide insights into energy consumption patterns and suggest areas where improvements can be made. One of the key benefits of using the Energy Efficiency Calculator is its ability to empower property owners with the information they need to make informed decisions. By identifying inefficiencies, users can take actionable steps to reduce energy consumption, lower their utility bills, and enhance their home's environmental footprint. Additionally, the recommendations for energy-efficient upgrades can not only lead to cost savings but can also increase the property's value, making it a smart investment for the future.

Inputs

Provide the following 3 values to run the Energy Efficiency Calculator:

  • Current EPC Rating [select] (required)
  • Annual Energy Cost (£) [number] (required)
  • Property Age (years) [number] (required)

What it calculates

This tool returns:

  • Annual Savings — primary result
  • Upgrade Cost
  • Value Increase

Worked example

For the sample inputs below:

  • Current EPC Rating: A
  • Annual Energy Cost (£): 1000
  • Property Age (years): 10

the Energy Efficiency Calculator produces:

  • Annual Savings: £0
  • Upgrade Cost: £0
  • Value Increase: £0

How it works

The result is derived through the following steps:

  1. ratings = { A: 1, B: 2, C: 3, D: 4, E: 5, F: 6, G: 7 }
  2. currentScore = ratings[currentEPC]
  3. potentialSavings = annualEnergyCost * (currentScore - 1) * 0.08
  4. upgradeCost = (currentScore - 1) * 2000
  5. valueIncrease = (currentScore - 1) * 5000
