Angel Building case study from CIBSE
Energy reduction was at the heart of the transformation of a drab central London office block into a CIBSE award-winning refurbishment.
The building has achieved BREEAM Excellent, giving proof of the effectiveness of the building services solution. It has also achieved a B rating Energy Performance Certificate, in itself impressive from a 1980s building.
Using the concrete carbon calculator and data from the University of Bath, the retained structure accounts for 39,500 tonnes of concrete, or about 30,000 cu m, which is equivalent to about 7,400 tonnes of CO2 or running the operational elements of the building for 13 years.
