BTS designed a faster, cheaper, and more accurate technology to measure air tightness in new buildings. But strict regulatory requirements around new buildings meant that its PULSE technology could not be accepted by the construction industry until it was validated in Part L1a of the Ministry of Housing, Communities & Local Government (MHCLG)’s building regulations CLT used its strong government networks to introduce BTS to the right people and helped shape theirmessaging. CLT worked with BTS to navigate the government system in order to submit its application to get PULSE validated. The results of the next round of government regulatory reviews should be announced soon, which (if accepted) will generate industry acceptance and facilitate sales CLT has helped BTS influence the regulatory environment to bring its PULSE technology to the market, which brings a competitive and environmental advantage over other well-established ‘Blower Door’ pressure testing systems. In the long run, the services that CLT have been able to help deliver will position BTS to compete more strongly with the existing technology.
