2. Introduction Russell Smith – Estates Manager – Engineering Section u In post for approximately 2 years, remit to manage the mechanical and electrical design and maintenance areas of the University’s Estates and Facilities Department. Robert Bradley – Energy Officer u In post for approximately 6 months, remit to reduce energy and water consumption and promote energy conservation.

3. View on University Russell: “When I arrived in 2004, I was surprised at the poor levels of control.” “The University was heating Bradford City Centre.”

4. University Built Environment - Aspiration u The University endeavours to maintain a comfort temperature of between 19ºC to 21ºC, throughout all academic/office areas. u Comfort temperatures are to be maintained between 8.00am till 5.00pm, Monday to Friday, during the ‘heating season’. u Outside ‘normal times’ heating will be provided to designated areas, 7 days a week from 7.30am till 11.00pm, during the heating season. u To use our systems effectively requires treading a thin line between no complaints and lots of complaints

5. What are the issues? We have inherited: u Old Buildings, typically 30 to 40 years old (inability to control - specific areas) u Very little consideration given to energy consumption u Poorly insulated building fabric u Large areas of single glazing u Poor heating systems

6. What is BMS (Building Management Systems) The definition of a BMS is: Building Management Systems are used in buildings to create a central computer controlled method of controlling, monitoring and optimising facilities such as heating, air- conditioning, lighting and security. These systems allow easier operation of facilities and reduce energy waste as facilities are used when they are needed.

7. Building Management System Popular misconceptions u I sit in my office pressing buttons to switch heating on and off u The controls software is all held at West End Building u “The radiator has gone off, therefore the heating is not working”

9. Richmond Boiler House

10. Heating Main

11. What have we done to date? u Improvements to the building fabric – cladding – Richmond Building u Improved controls in the main boiler house and zone controls – Richmond & Horton Buildings u Benefits of this have already been recognised, a 9% reduction in heating energy consumption Residual issues u Drafts from sills/badly fitting windows

12. What have we done – Chesham Building Case Study Findings u No internal temperature control u Constant heating emissions from the heating mains which travel through the buildings u Various heating and hot water systems are connected together leading to operating temperatures being at a high level to achieve set points.

13. What have we done – Chesham Building Case Study Recommendations u Bring the main ventilation systems up to standard u Install control valves to limit the temperature of the pipe work from the campus mains u Re-configure pipe work to separate the services u Install BMS controls u Estimated cost of these remedies 300k Expected Outcomes u Improved control of the internal environment u Ability to use ‘free cooling’ u Reduced running costs

14. What's for the future (1) u Reducing CO2 emissions is essential, with carbon trading on the horizon. u Monitoring and Targeting (M&T) software u Installing automatic meter reading to allow for more accurate monitoring of energy use. u Combined Heat & Power (CHP) u Biomass Boilers

15. What's for the future (2) u Extending the district heating system and altering the method of operation u Expanding the computerised Building Management System (BMS) u Comfort cooling – great pressure to install. This can only be considered following a full evaluation, at present this is not possible. u Improving the thermal performance of all building stock

16. Actions for 2006/2007 Current projects: u Phoenix South West new heating controls and remote metering u Phoenix North West remote metering u Richmond Building electricity supply automatic meter reading u Richmond Building gas supply automatic meter reading u Richmond Building new heating controls to D,E,K,L and M Floors u IPI Building automatic meter reading u JBPL automatic meter reading u Sports Block automatic meter reading u Emm Lane new controls and remote metering u Yvette Jacobson new controls and remote metering u Main campus new controls to the district heating main

17. Cost VS Consumption

18. To Summarise u Estates & Facilities are aware that there are comfort issues around the campus and are endeavouring to tackle these issues. u However patience is required, many of these issues are historical. u The University is committed to this path, to ensure that it meets legislative and environmental targets.

19. Thank you u Any questions?
