Sourcing Sustainable Steel

Posted on November 29th 2021

Sourcing UK steel won’t improve the sustainability of your projects and steel with a high recycled content isn’t the best way to reduce embodied carbon. Wait a minute, that doesn’t sound right; sourcing locally reduces A5 transportation emissions whilst a high recycled content engages with the circular economy, reducing A1-A3 materials emissions. Right? The truth is that is an over-simplification …

Air Quality Monitoring for Safe Indoor Working Spaces

Posted on October 27th 2021

CO2 monitoring in commercial spaces is a cost-effective way to manage spread of Covid-19 through optimising ventilation. Poorly ventilated spaces increase the risk of virus transmission. Yet, it can be difficult to manage effectively because air is invisible, making ventilation a less obvious mitigation measure. Monitoring indoor CO2 concentration is a useful proxy for understanding occupancy levels and ventilation rates, …

The Commercial Value of BREEAM Certification

Posted on October 27th 2021

Recent research shows that full BREEAM certification can lead to appreciable increases in rental values of commercial spaces. Tenants and lessors understand that sustainable buildings are more likely to be protected against future legislation changes, meet strong mandates coming from investors, and meet occupier demands to provide high quality working spaces for their employees. BREEAM aims to significantly reduce building …

Domestic Hot Water is getting cooler

Posted on September 14th 2021

CIBSE has recently published new guidance on domestic hot water temperatures for heat networks. The new document recommends the adoption of a 50°C target for the DHW generated at the hydraulic interface unit (HIU) outlet, with 45°C being reached at the kitchen tap within 45 seconds or less (notable exceptions exist, such as for vulnerable customers). The document has been …
