5. Quick Energy Assessment
• Using reference rooms instead of a
whole building model
• Characteristic values to estimate the
energy demand according to room
level
• Energy classes describe the
occupancy/function of the building
energy
class
office, laboratory,
lecture hall, etc.
Reduction of the required amount of input data – energy classes

5. Quick Energy Assessment
Comparison: simple and detail method
M1: reference room method (simple)
M2: whole building simulation (detail)
• 4 different buildings
• 10 building classes
• Not yet suitable for every building
• Time demand: M1 <<< M2 !

5. Quick Energy Assessment
Priority list for the retrofit
Correlation shows:
• Individual building performance
• Cost saving potential
Goals to achieve
• High energy efficiency
• Low energy costs
Universities
as role models have to
achieve both goals!

Campus = buildings + function
Information = data + data-handling
Modelling = methods + tools
