What is the EPI of your Building?

In this article we will learn how two different buildings that are both considered platinum might differ in their net energy consumption.


When it comes to evaluating the sustainability of a building, the Energy Performance Index (EPI) plays a pivotal role. These remarkable structures have been honored as Platinum Rated Buildings for their sustainable qualities. Nevertheless, there’s a deeper layer to these edifices that often leaves their platinum status open to scrutiny. 

We often hear about Platinum-rated buildings, but do they always have the lowest EPI?


The EPI (expressed as kWh/m2/y) stands as a critical indicator that unveils the authentic energy efficiency, resource utilization, and overall sustainability of a building.

In the case of a platinum-rated building, the EPI may range from 100 to 50 kWh/m2/y. While the Platinum rating signifies a high level of environmental consciousness, it doesn’t inherently quantify the building’s actual performance in numerical terms.

Not all platinum-rated buildings necessarily have the lowest energy consumption. Instead, the EPI acts as a mileage gauge for these buildings, akin to a car’s fuel efficiency (liters per kilometer). Hence, it’s imprudent to presume that all platinum-rated buildings inherently provide top-tier energy efficiency.

To truly comprehend a building’s real-world environmental impact and efficiency in their quest for genuinely sustainable spaces, customers should delve into its EPI.
