REVEALed: a new initiative to showcase and compare the world’s most energy efficient buildings.

REVEALREVEAL – a new building energy performance nutrition label and benchmarking scheme to showcase and compare the world’s most energy efficient buildings. 

Reveal is the latest programme from the International Living Futures Institute (the Institute behind the Living Building Challenge, Living Product Challenge, Declare and JUST) to provide visible and benchmark-able energy data based on real, measurable data. Reveal is aimed at certified Living Buildings, net zero buildings, LEED buildings, BREEAM buildings, Passivehouse projects – or indeed any project with accurate measured energy data. It should be of great interest to the facilities Management and Property sectors

REVEAL taps into performance based reporting – an integral part of the Living Building Challenge and Net Positive Certification to provide a new platform for projects to showcase how efficient they are relative to other buildings.

Evidence for the Reveal using the EUI – Energy Use Intensity index – would be validated from utility provider data and audited by ILFI. Reveal Labels are date stamped and will be renewed on a two-year basis to essentially become ‘nutrition’ labels for building energy performance.

Organisations can use their label on their websites and marketing materials to tout their achievement in being one of the world’s most efficient buildings – and see how their project stacks up to other exemplary projects.

Energy Use Intensity (EUI) indicator: In the absence of a standard or benchmark it is difficult to benchmark energy uses between buildings. Simply measuring the amount of energy used per a chosen time period does not take into account building size, configuration or type of use. The use of an Energy Use Intensity (EUI) indicator provides a means to normalise the way that energy use is compared between various types of buildings, and evaluate the means of reducing overall energy consumption.

When using EUI, energy use is expressed as a function of a building’s total area or “footprint”. For Reveal, as is common in the US, EUI is expressed in energy used per square foot of building footprint per year. It is calculated by dividing the total gross energy consumed in a one-year period (kilowatt-hours or kilo-British Thermal Units) by the total gross square footage of the building ie KbTu/sqft/year  In the UK and elsewhere this would be KWh/m2/year. See Calculating a Building’s EUI

The International Living Future Institute (ILFI) will begin issuing the new energy label, called “Reveal,” in late 2015 according to Eric Corey Freed, vice president for global outreach at ILFI.

  1. I was reminded by your post of another certification approach by LEED : Dynamic LEED giving real-time metrics (see this article by Wanda Lau – http://www.ecobuildingpulse.com/news/a-leed-dynamic-plaque-for-every-building-new-and-old_o)
