Measured Energy Performance

Non-invasive thermal performance testing

An average performance gap of 60% exists between properties' predicted and actual thermal performance. Measured Energy Performance provides an accurate energy efficiency rating by using real-time data to measure the thermal performance of a building pre- and post-occupancy.

  • Non-invasive
  • Affordable
  • Scalable

The benefits of
Measured Energy Performance

Verify performance

Check your property is performing as promised.

Measure retrofit improvements

Compare how your properties perform before and after the installation of energy efficiency measures, and identify the most cost-effective combinations.

Identify underperforming properties

Identify properties with a poor thermal performance and effectively plan a co-ordinated retrofit plan with measurable outcomes.

Get an improved estimate of annual kWh consumption

Required to claim ECO funding and a pre-requisite for many insurance companies

What is Measured Energy Performance?

A performance gap can exist between design intent and how a property actually performs for a variety of reasons. Measured Energy Performance uses real-time information gathered from multiple data points to produce an energy efficiency rating that is precise and reliable, and can be easily carried out across multiple properties. It is often used within Building Performance Evaluation as part of a Post Occupancy Evaluation report., but it can also be used as a standalone service.

Once we have analysed the data, we will provide you with a detailed report which compares your predicted/ As-built SAP EPC rating with a precise measured energy rating, along with expert analysis on how to improve your energy efficiency rating and optimise your properties. You can view an excerpt of a sample report here.

Non-invasive and scalable

The assessment is performed with little intrusion and with the owners in-situ.

Small temperature sensors are placed around the house (usually on a book case or on top of a cupboard) which gather data over a 3 week period. Our expert team of energy consultants combine this data with weather and energy use information to assess how the house performs.
