Circular route: New Street station lighting retrofit

To minimise embodied carbon in the retrofitting of nearly 900 luminaires at Birmingham’s New Street station, Q Sustain used CIBSE TM65 to calculate the potential savings of reusing existing luminaires. The firm’s Lovely Chavan and Yara Bekdache explain how it saved more than 163 tonnes of embodied carbon

Measuring up for net zero: interview with David Partridge

As one of the most prominent figures in property, David Partridge is in an ideal position to oversee the governance of the Net Zero Carbon Buildings Standard and ensure a definition for net zero is embraced by those who develop, own and build real estate. Alex Smith reports

Facing up to embodied carbon in façades

Façades account for up to 30% of a building’s embodied carbon, which is why the Centre for Window and Cladding Technology is working to produce a new methodology to bring consistency to life-cycle assessments. Buro Happold’s Teni Ladipo reports

Buildings for the future

Future structures will be carbon negative, climate resilient and integrated into the local community, according to engineers and sustainability experts at Buro Happold. They tell Andy Pearson why the next generation of buildings must be designed today

Calculating whole life carbon in heating and cooling systems

To minimise carbon emissions from heating and cooling, the whole life of a system must be taken into account. Hoare Lea’s Will Belfield and Mathew Stark compare three common cooling and heating systems to see which has the lowest impact over a 60-year lifetime

Heart of the matter: calculating embodied carbon using TM65

Embodied carbon in MEP equipment makes up a large proportion of building emissions, but is hard to measure. Elementa Consulting’s Louise Hamot and Clara Bagenal George explain how CIBSE’s TM65 methodology estimates components’ environmental impact

Getting to grips with whole-life carbon

Research into the amount of carbon embodied in building services is scarce. Louise Hamot reports on an Elementa study that attempts to measure the whole-life carbon impact of building services
