The Low Energy Building database

The AECB holds information on over 400 low energy projects (new builds and retrofits) on the Low Energy Buildings Database (LEBD). The LEBD is an online resource created by the AECB, that anyone can view for free to learn about real projects and how they turned out.

For those working in the world of low energy buildings, there is so much to be gained from understanding how projects achieve high standards, and the real life challenges that sometimes have to be overcome to get there.

With your help this valuable resource will continue to grow. If you have designed or completed a high performance, low energy building please share it on our database.

Note : As from 30/06/23 the LEBD will not be available for further uploads or certification to the AECB standard.  We are migrating all the data to a new platform which will be launched in Summer 2024.  The current database is an old legacy system which has come to the end of it's lifetime.  If you wish to certify please speak to an Approved Certifier or email [email protected].

Many projects are being designed & built to the AECB Standard or Passivhaus - complimentary building standards based on the same rigorous approach
