  1. From Heat & Light to BEST Professor Colin Pattinson Head of School Computing, Creative Technologies and Engineering The JISC Heat & Light by Timetable project

  2. The problem • Mixed estate • Age • Size • Location • Use • Heating control • Rooms heated 8 – 20:00, Mon – Fri • Irrespective of actual use

  3. Teaching space use • Timetabled according to operational requirements • Rooms are • Pooled – available to any user • Specialist – e.g. laboratories • Meeting rooms

  4. Example room use – pool

  5. Example room use – specialist rooms

  6. Example room use – meeting rooms

  7. The timetable Centralised system (CMIS)

  8. Building Management System

  9. The idea • Use the CMIS data to determine when rooms are in use; • Use this information to generate heating control • All we need is a link between CMIS and BMS

  10. Time lags • Takes time to heat a space, • Residual heat remains afterwards

  11. Interface software • Retrieve data from CMIS • Room number • Day • Start & stop time • Convert to BMS control sequences • Time zone start and stop

  12. Building “blocks” • BMS operates HVAC controls based on zones • CMIS works on a per-room basis • Need to allocate rooms into BMS blocks • If one room in a block in use – the whole zone needs heating

  13. Next steps • Fuller operation of the system • Two more research projects • A PhD project extending the idea • A modelling project to calculate estimated savings • Building Energy Scheduling by Timetable

  14. BEST – Building Energy Scheduling by Timetable • Thermal modelling • Includes heat flows • Allows estimated energy saving • For retrofitting

  15. BEST outputs • Potential 10% energy saving • See our upcoming paper • PREDICTING AND OPTIMIZING THE PERFORMANCE OF A TIMETABLE LINKED BUILDING ENERGY MANAGEMENT SYSTEM • To be presented at Building Simulation and Optimization 2014 23/24 June, UCL
