5 Space Costing • Where to begin • Measure all space - no quick solutions • Categorise labs, offices, special facilities etc • Must cover every room • All balance must be included somewhere • Coding Structures !!!

6 Possible Space Types • Storage areas, barns etc - virtually no running costs but need to be replaced • Office “type” space - ie limited services and no forced ventilation • Serviced space including teaching labs - might have 2 to 5 air changes per hour i. e. One or two fume hoods • Highly serviced space - research labs and special facilities including animal units - usually forced air change 5 a/c up.

7 The draft model • Establish which costs driven by space • Energy, Cleaning, Maintenance etc. • Do the costs increase with service type? • What ratios apply to the higher serviced space • Use your own building data to determine a first iteration of cost

8 Bristol Weightings • Type 0 1 2 3 0. 2 0 1 1 1. 5 1. 8 3 3. 4 Weight Mtce Energy • These weightings derived by crude analysis and experience

9 Deriving the Space Cost • Take all budget lines • Apply rating as already shown for each line • Allocate back all current costs for “today’s” budget • This gives a start point for costing

10 Validating • Take a building with predominantly one space type - e. g. An office or research unit • Meter it, gas, electricity, water, mtce • Calculate real cost • Check against weightings and iterate result

11 The result

12 Total Costs

13 Capital Depreciation etc

14 Issues for f. EC • Research & Teaching happens in the same space • How do you account for time (salaries? ) • Metering - might not be extensive • Academics won’t believe you • A lot of effort to measure • Keeping track of changes • Perfection is not achievable
