The Worcester School Sports and Drama Hall also known as “Bartholomew Barn” was completed in 2016 as the certified passive house & Saint-Gobain Multi-Comfort building with a floor area of 371 m2. The client was keen for Bartholomew Barn to fit in with the architectural character for the school’s rural setting, which includes a listed Georgian farmhouse but also an ‘eclectic’ mix of historic buildings, many of which are timber-framed.
Another factor in its favour is that it is thermally lightweight, meaning it will respond to temperature changes more quickly. This is important for a multi-purpose building that might need to be at 16°C for active sports uses, and then rapidly heated to 21°C for drama or a community event.
What is Saint-Gobain’s Multi-Comfort building? By John Christophers of Associated Architects. From PassiveHousePlus, 2018.
The protocol is based on the fabric-first approach of the passive house standard, with its emphasis on solar gain, a highly airtight and insulated building fabric, and high-quality ventilation. But it also adds factors like daylighting and acoustic comfort for a holistic approach focused on all-round occupant health and comfort. “What we like about the Multi-Comfort standard is that it recognises sustainability is a complex multi-faceted concept,” said John Christophers of Associated Architects. “Passive house as a standard is excellent on airtightness, thermal bridging, fabric-first etc., but says nothing about considerations such as acoustics, VOCs, daylighting etc., all of which are included in Multi-Comfort.”
