MOST SUSTAINABLE PUBLIC SECTOR ORGANISATION – EDUCATION


HIGHLY COMMENDED Leeds Metropolitan University


THE INITIATIVE Carnegie Village: 479 bed halls of residence, located in a conservation area with grade II listed buildings, occupied September 2009. Partners: UPP, Leeds Met, Shepperd Construction. The Rose Bowl: For the Faculty of Business and Law, 12,000 m2


• Rainwater


harvesting and solar thermal hot water


• Landscaping and biodiversity project


in the centre


of Leeds behind the Civic Hall, occupied in April 2009. The brief: To implement our Sustainable Construction and Sustainability Policies, establish costs and data to inform future policies/decisions and evaluate real life experiences of sustainable living/working. Sustainable initiatives include:


Carnegie Village: • 2 townhouses certified to Passivhaus (£37,000 investment first certified building in the UK).


• BREEAM excellent achieved • High levels of insulation and airtightness


• Mechanical Heat Recovery Ventilation System


• Low Nox, A-rated gas condensing boilers


• Low water use aerated taps and showers


• ‘A’ rated Green Guide materials • Full, low energy lighting/passive infrared (PIR) to common areas


• WRAP assessment 16.5% recycled content. Original target of 10%.


• 5,000 tonnes of demolition waste reused on site

ENVIRONMENTAL AND SOCIAL BENEFITS Carnegie Village Passivhaus (Nidd 1 & 2) • Reduced utility costs for all townhouses and overall carbon savings


• Further reduction in gas costs and carbon savings for the Passivhaus


• Fig 1 highlights the importance of gas to reduce the overall carbon footprint


• Environmental benefits of wood and modular construction.


• Wood being the most sustainable construction material


• Modular construction reducing waste at source


• Dimensioning accommodates standard building material sizes:


• Reducing waste at source • Shorter construction times resulting in less transportation of goods and staff


• Simple plan configuration: • Reduces waste, • Airtightness targets easier to achieve


• Efficient space heating by eliminating cold and hot spots.


• Students first hand experience of living and working in a sustainable building


Rose Bowl • Significantly lower energy use than predicted
