building for education project report
‘The idea of doing Passivhaus at this scale was a very new thing when we came
to the project’ Jonathan Chadwick
The centre is characterised externally by its chunky white-rendered colonnade, green wall and curtain walls with narrow slotted windows and red brick slips
performance asset rating, placing it in the EPC ‘A’ category. “On a standard build we would have needed a rooftop photovoltaic array about twice as large as the 150 m2
array we
have on the building to reach the same EPC rating. Passivhaus meant we were starting from a very low energy base point,” says Chadwick. Unusually for a building of its type, the Centre is targeting
a Display Energy Certificate ‘A’ rating, to demonstrate that it performs to the same high level of energy efficiency in operation as it does in design. “It is not unusual for an EPC ‘A’-rated building to perform
to an ‘F’ or ‘G’ standard in operation. We are trying to make a commitment to say, it was designed to achieve this standard and if it doesn’t we need to get to the bottom of why,” says Chadwick. A three-year ‘Soft Landings’ period will see the main
contractor, design team and university stakeholders monitor energy usage in operation and implement measures designed to drive it down. Indications so far are encouraging. According to Willmott
Dixon, predicted energy consumption at the new building is less than a fifth that of the existing school of medicine, located across the road, at 80k Wh/m2
compared to 550 kWh/m2 .
The project is a lesson in energy performance that is relevant to educational institutions the world over.
