Designed to Passivhaus standard, Associated Architects‘ new boathouse at King’s School, Worcester started on site last month. The Michael Baker Boathouse is the eighth building to be completed as part of the architects’ ten year masterplan for the school and is located at the edge of Worcester’s historic city centre.
The existing one storey boathouse will be replaced by a two storey, 821 m² building that raises the main areas above the flood level; connects it to the school via a walled garden and improves views along the River Severn. Facilities include boat storage, changing, training and teaching rooms and a school community reception space.
The premise of reduction is adhered to here, with the annual heating demand below Passivhaus standard <15kWh/m2 and airtightness at Q50=0.6m3/m2hr. Renewable energy features prominently with a mix of solar thermal to supply 75% of hot water and solar PV for 50% of electrical demand. Heating will be supplied by a wood pellet biomass boiler. The services engineer for the project is LEDA.
Passivhaus certification is anticipated upon completion in December 2011.
