Building Energy Benchmarking 101 - What is Energy Benchmarking?

What is Energy Benchmarking 

 It is to compare the Energy Use Index, i.e. energy used per floor area, of different buildings fairly by

• Categorization   – Grouping the similar types of buildings together
• Normalization   – minimize the objective impacts(weather,   occupancy) on the building’s energy use
• Separation     – excluding the special energy use in the buildings   (e.g. sever rooms)

What information it provides

Benchmarking systems usually tell you what your building's energy performance is, and probably some additional information as well. Take Display Energy Certificate (DEC) (UK) as an example:
