How to Retrofit

EUI is a measure of total energy used within a building in a year and is expressed in kilowatt-hour (kWh) per gross floor area (sqm). While there are many global certification programs that facilitate benchmarking and minimum performance standards of buildings (Energy Star, BREEAM, Green Mark, LEED, Greenstar, NABERS, etc.), EUI is unique in that it provides a somewhat universal indicator of energy efficiency. After understanding your EUI a good next step is understanding how energy is being consumed - this can be understood by undertaking an energy audit assessment. HOW IS EUI MEASURED?

The below pie chart indicates the percentage of energy consumption in a typical office building (this doesn’t include tenant consumption): HOW TO REDUCE EUI?

The good news is that if your building’s EUI is higher than average, you can retrofit your highest energy consuming systems. Below is a list of common energy guzzlers that are worth considering retrofitting for a cleaner, greener upgrade:
