Comparison data City Site March 09 – Feb 10 kWh/m2


kWh/occupant


• Total consumption estimated at 5.9 million kWh


• Actual consumption of 3.7 million kWh


• Fig 2 clearly shows that intensive space utilisation and reduction (2,000m2


saved on construction)


in new builds is significantly more efficient per occupant.


• Use of space in semester one in the Rose Bowl was 74% compared to 57% across the rest of the Estate.


• CHP provides 12% of the electrical consumption required during peak conditions.


• Avoiding the production of 122 tonnes of Carbon Dioxide


• Reduction in transmission losses through on site generation saving a further 4.56 tonnes of carbon dioxide


• 21% reduction and intensive use of space


• Associated materials and energy savings on a reduction in 2,000 gross square meters.


• Rainwater harvesting accounts for 19% of total water use


• Reducing energy consumption related to water treatment


• Reducing strain of water resources


• Reducing biological impact on water courses


• Composting and recycling area built into the design for the canteen kitchen


• Contributing to our target of zero waste to landfill

OTHER BENEFITS Carnegie Village • 479 students taken out of the surrounding neighbourhood


• Students sign an agreement not to bring a car to Leeds


• Students mostly live and study on campus – reducing the need to travel


• Reduced parking on residential streets


• Increased use of sustainable modes of transport. Mainly on site bus services and cycling


• Increased use of on site facilities – pool, gym, SU bar, shops and refectories


• Modular construction • Shorter construction period • Reduced construction costs • Increased income


Rose Bowl • Energy generated by the CHP equates to savings of £15,968/annum (7p/unit)


• Payback period of 5.44 years (capital cost of £87,000) compared to 4.1 years in the feasibility study


• Revenue savings of £239,520 based on a 20 year life


• Carbon savings of £1,500 on the Carbon Reduction Commitment


• Rainwater harvesting saves £1,500 on the water bill, providing a payback period of 30 years (based on 12 months data).


• Linking value engineering with BREEAM assessment was key to keeping the focus on implementing sustainability initiatives.

• Financial savings on capital and revenue costs (rates, utilities etc) associated with the 2,000m2 saved on construction.


• Comments from post occupancy evaluation ‘what do you particularly like about the Rose Bowl’:


Staff


• The natural light that comes into the building and into the offices and teaching spaces


• The meeting rooms and seminar rooms are generally fit for purpose and allow in plenty of light, as they are generally externally-facing.


• The windows and modern feel - good light


• secure bicycle storage, and centre of town location


• Cycle spaces and cycling facilities


• open plan offices • seminar rooms • The seminar rooms facing external are great - mainly due to natural light and good space


Students


• Open, spacious, light, • Good secure cycle storage


Marketing opportunities. Both projects were highly commended


in the Leeds Architects Awards 2009 New Building Category which focused on sustainable and innovative solutions. The Carnegie Village won the national BREEAM Award in 2010. Both projects have been put forward in multiple categories in the RICS Yorkshire and national awards.


RELEVANCE TO THE SECTOR Supports HEFCE’s Strategic statement on promoting sustainable development in higher education and carbon targets for the sector via examples such as more efficient use of space (Rose Bowl) and reduction of energy at source (Passivhaus, Carnegie Village). Leeds Met will share energy consumption details with the sector to benchmark passivhaus and standard townhouse performance against existing stock to enable other HEI’s to build the business case for Passivhaus design. Eliminating heating requirements will go a long way to achieving HEFCE carbon targets.


Sharing lessons learnt with other HEI’s will reduce future construction costs, improve performance and increase the
