The proposed Bitterne Park School is a new build EFA funded secondary school located in Southampton, designed for a future capacity of approximately 1800 students. The key project challenges included a 15% carbon reduction through Low and Zero Carbon Technologies, BREEAM Excellent to be achieved and full compliance with the EFA Facilities Output Specification.

Through our work on schools such as Bitterne, we have developed robust practical solutions to meet some of the EFA’s more unique and challenging requirements. These solutions have been made possible due to the combined expertise of our computer modelling and energy simulation specialists, our energy reduction experience and the breadth and depth of practical design and installation experience within our engineering team.

We worked with Make Architects and Mace Developments on the Westway Botley redevelopment as part of a multi-disciplinary team on a mixed-use scheme consisting of student residential and retail space including a 6 storey Premier Inn with 121 bedrooms above a supermarket. The design was based on the standard Premier Inn specification and a 30% improvement against building regulations was targeted with CHP generating hot water and electricity and a large PV array on the roof to meet the meet the Premier Inns renewables target.
