  1. DEPT OF ESTATES AND FACILITIESEngineering Team Too hot, too cold, just right Presented by: Russell Smith – Estates Manager (Engineering) Robert Bradley – Energy Officer

  2. Introduction Russell Smith – Estates Manager – Engineering Section • 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 • 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 • The University endeavours to maintain a comfort temperature of between 19ºC to 21ºC, throughout all academic/office areas. • Comfort temperatures are to be maintained between 8.00am till 5.00pm, Monday to Friday, during the ‘heating season’. • Outside ‘normal times’ heating will be provided to designated areas, 7 days a week from 7.30am till 11.00pm, during the heating season. • 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: • Old Buildings, typically 30 to 40 years old (inability to control - specific areas) • Very little consideration given to energy consumption • Poorly insulated building fabric • Large areas of single glazing • 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 • I sit in my office pressing buttons to switch heating on and off • The controls software is all held at West End Building • “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? • Improvements to the building fabric – cladding – Richmond Building • Improved controls in the main boiler house and zone controls – Richmond & Horton Buildings • Benefits of this have already been recognised, a 9% reduction in heating energy consumption Residual issues • Drafts from sills/badly fitting windows

  12. What have we done – Chesham Building Case Study Findings • No internal temperature control • Constant heating emissions from the heating mains which travel through the buildings • 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 • Bring the main ventilation systems up to standard • Install control valves to limit the temperature of the pipe work from the campus mains • Re-configure pipe work to separate the services • Install BMS controls • Estimated cost of these remedies 300k Expected Outcomes • Improved control of the internal environment • Ability to use ‘free cooling’ • Reduced running costs

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

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

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

  17. Cost VS Consumption

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

  19. Thank you • Any questions?
