About Us

We are Build Test Solutions (BTS), innovators in building performance measurement. In partnership with likeminded innovators, universities and leading practitioners, our mission is to make in-situ building performance measurement accessible and affordable.

We coordinate a UK based product development, manufacture and assembly supply chain, supplying building performance measurement solutions to energy assessors, surveyors, contractors, utility suppliers, technology providers and other built environment specialists.

Our Technologies

We specialise in navigating the famous technology innovation “valley of death”, transitioning technologies from innovation to product. More information about our core technologies can be found below.
Pulse - Air Leakage Test

Pulse - Air Leakage Test

Pulse is our pioneering approach to fabric air permeability measurement which releases a low-pressure air pulse for realistic and accurate measurement of air leakage in seconds.

U-Value Measurement

U-Value Measurement

Take the guess work out of determining elemental heat loss with our technologies for measuring in-situ U-values.

Smart HTC

Smart HTC

Measure whole building fabric heat loss (also known as a Heat Transfer Coefficient or HTC) using our algorithm that interfaces with live smart meter data.

Latest News

A turning tide for the measurement of buildings?

The recent Building Performance Network report, ‘State of the Nation Review: Performance Evaluation of New Housing’ was published this week. The report provides more evidence that we simply don’t know the real performance of our buildings, underwhelming policies based on predicted performance all of which leaving buildings at risk of unintended consequences.

Pulse 2.0 to be unveiled at Futurebuild 2020

Following the recent success of Pulse, Build Test Solutions have developed Pulse 2.0, a more robust, lightweight version of the previous system, which will be unveiled to the public at this year's Futurebuild event in early March.

We aim to improve the performance of UK housing stock by developing technologies which drive a culture of regular quality assurance testing and accountability.
