Would it be nice if in every single office you entered you could see the energy efficiency cerficate displayed?

That would create a healthy competition for greener buildings, based on transparency and standardised metrics. Employees would complaint to their facility management colleagues for embarrasing performance and landlords would have an incentive for improving energy performance of buildings.

That’s the power of transparency.

Although this is partial rather than full transparency.

Full transparency would be to display g CO2 of the total life cycle of a building. But DECs are absolutely essential because they address a quick win: the inneficies in energy consumed by buildings. I really thing this subtle self-name & shame will add more value to green buildings than rating tools. And the most interesting bit, it will reduce value of less green buildings.

UK-GBC and BPF have joined forces to lobby to extend DECs to commercial buildings by 2012.

defraEarlier this week, the UK Department for Environment Food and Rural Affairs (Defra to you and me) joined the Department of Energy and Climate Change and the Home Office in publishing real-time energy consumption data online. If you go to this page on their web site   you can see a graph spiking up and down showing energy units used per hour and use over the past 24 hours at its main London headquarters building. It is also clever enough to disclose the energy cost per hour and carbon emissions.

Whether this is simply a gimmick or real progress towards full transparency – I think it is certainly a good start. The government has committed to cutting carbon emissions across all central departments by 10% by next May, so it will be interesting to what Defra does next (and which departments follow suit). It has already promised that as more data is collected, it will publish results for different time periods (use per week, month and year).

So, Defra is definitely making a move in the right direction, but it needs to look at more than just energy consumption. Real carbon transparency will depend on reporting total carbon emissions during the whole life cycle of a building – including the energy used to produce building materials and furniture (and carpet!). Also, it’s not just carbon emissions that have a negative impact on the environment. Hopefully, one day in the not too distant future, government departments will also report on waste production and water usage in a similar way.

In my opinion, the best way for the Government (or any organisation for that matter) to get reliable and validated information on its full environmental impact, including carbon emissions is to use Environmental Product Declarations  and continue to provide just the facts.

The EU adopted a recast of The Directive on energy performance of buildings (2002/91/EC) on 18 May 2010. This was done in order to strengthen the energy performance requirements and better organise its provisions.

 Buildings account for around 40% of energy consumption and 36% of CO2 emissions.  As much as 80% of the operational costs could be saved through integrated design solutions.
