Enterprise Centre in Norwich! BREEAM & passivehouse!

Enterprise Centre in Norwich is an commercial building aiming to achieve BREEAM Outstanding and passive house certifications designted by Architype. The total area is 3,400 m² and the floor-to-ceiling height is 3,3 m to create sufficient volume to cope with temperature rise and ensure enough daylight. The building is built from 70% of bio-based materials and equipped with 480 m² of photovoltaics panels. The unusual or less specified materials have been incorporated in a building such as Thetford timber, Norfolk straw and heather, hemp. Sustainable low carbon features include mechanical ventilation with heat recovery, triple-glazed windows, photovoltaic panels and solar heating.

Article from CIBSE Journal September 2015 portraits a project of Enterprise Centre in Norwich as an commercial building aiming to achieve BREEAM Outstanding and passive house certifications. The building is wrapped in thatch composed of 250 mm thick layers of straw set in unique timber-cassettes. The building sits on a 375 mm thick concrete (made of 38% embodied carbon) raft foundation incorporating three layers of 98% recycled steel reinforcement and incorporating a special polystyrene insulation. The E-shaped building maximizes the amount of daylight through triple glazed windows and it is built to minimize embodied energy and life-cycle costs. The building is equipped with demand controlled ventilation system controlled by occupancy and CO2 sensors via three ventilation plant rooms: in each of two wings and in a central auditorium. The 300 seats auditorium also has a small cooling unit for comfortable temperature in summer.

Presentation by Gareth Selby for UK Passive House conference 2014. The presentation showcases the base case scenario for design of the Enterprise Centre in Norwich compared to the simulation scenario without mechanical extract in summer, 2 ACH summer natural ventilation, heat pump coefficiency of COP 4 (400%), with 2 massive surfaces (108 Wh/K per m² capacity) and with all massive construction (204 Wh/K per m² capacity). The presentation also includes shading optimisation and domestic hot water design for a very highly occupied building.
