Building Performance Knowledge Hub

Our knowledge hub is a free resource to help understand building performance measurement, building physics and home energy efficiency. The case studies and technical reports explore real-world use cases of air tightness testing, building performance evaluation and post-occupancy evaluation.

Buildings Behaving Badly: why are buildings not performing as predicted

In this webinar we present compelling findings from our unique performance database. This extensive dataset allows us to quantify precisely how much models and measurements differ and why.

Case Study

Balancing heritage with a low-carbon future at The Arc

The Arc has a goal to reach net zero by 2030, so a decarbonisation plan was needed. Using Winchester City Council’s Greener Futures Fund and internal funding, a study of early-stage options for retrofitting and refurbishment was commissioned.

Case Study

Preserving history while testing for the future

Unlike modern buildings, heritage buildings require a deeper understanding of their materials and construction methods to be able to analyse their performance and measure accurate u-values, which is where Heat3D comes into its own.

SmartHTC measures building health and efficiency in one easy process

Technical Guide

The Essential Guide to SmartHTC

It is not uncommon for residential buildings to measure as having heat loss that is HALF that predicted by an energy model. The result is that energy efficiency upgrade measures can be incorrectly specified and not deliver on expected cost savings.

Pulse system in a home

Case Study

Measurement technology improves surveying

The number of homes with an Energy Efficiency Rating of C or above was 46 per cent in 2022. This is up from 13 per cent in 2010, so whilst things are moving in the right direction much more must be done to meet net-zero targets by 2050.
