Sustaining our Future by Rebuilding Our Past

‘Sustaining our Future by Rebuilding Our Past’ – The title of the presentation given by ASHRAE President Gordon Holness, and the highlight of the recent annual ASHRAE Presidential event in the Institution of Mechanical Engineers, Westminster, London. This was a joint meeting with CIBSE, ASHRAE Group and the IMechE CBSD.

The current ASHRAE President firmly believes that energy efficiency in existing buildings is the key to a truly sustainable future… and with existing buildings being responsible for 40% of primary energy consumption in the US, you can see why.

One of the most fascinating things about this presentation was the ability of Gordon Holness to produce detailed facts & figures at will. He has clearly been preaching the role of the existing buildings and their impact on our environment for quite some time now… Kudos!

Personally I believe to achieve an energy efficient existing building; we must first understand its complexity. I also believe that along the critical path to achieving an energy efficient existing building, we must first encounter its ‘virtual building’. Once calibrated, the virtual building with BIM will be the key to the design, redesign or retrofit. The existing building landscape as I see it is as below.

Bottom line: In this economic climate, achieving an energy efficient existing building can make all the difference to maintaining commercial survival or increased financial prosperity.

By the way, it is said that 75 – 80% of all buildings that will exist in 2030, exist today! I wonder how much of an issue carbon tax will be in 2030!
