As we reach the end of the 100 Days of Carbon Clean Up campaign, our horizons are naturally moving forward to new challenges and our thoughts are focused on what comes next.

Everywhere I go the campaign is acknowledged as a success and praised for the good publicity it has created for CIBSE. It gave us evidence of the considerable interest in the wider world for combating carbon emissions, and we were delighted that over 550 companies signed up for it.

The wider initiative, which the Carbon Trust has also helped fund, included the development of the Low Carbon Consultants training and registration. It has generated a trained body of people whose competence to advise on building energy matters can be attested to.

But the 100 Days of Carbon Clean Up has underlined the difficulty of initiating even the simplest audit of energy use. Those who took part were given copies of TM22: Energy assessment and reporting method, but we are struggling to get carbon returns back. Less than 10% of participants have completed one.

We had hoped that we would achieve a significant change and get them to see energy consumption management as one of their key deliverables. It is clear that this has not been achieved.

Does the lack of response mean that UK business wants to get involved but still fails to understand the vital importance of measurement? Or does it mean that an apparent lack of measurement skills in client companies cannot be overcome simply by telling people how to do it?

We will be looking to see if CIBSE members, and in particular our expert cadre the Low Carbon Consultants, can help all those who took part.

As we look forward we are all determined that CIBSE should be the informed, dominant voice on shaping the future for the built environment for our members and society at large. We need to be clear on where we are going. We continue to develop our influence with government and key policy makers, but we must deal in facts.

For our part we are pressing on with using Delta House as a 鈥淭est Model鈥 as part of the Carbon 60 Competition. There are challenges to be met, but unless we are serious about this, we shall, as engineers, be vulnerable to the criticism that subjective arguments are more important than genuine commitment and well researched arguments.

And what does CIBSE look at next? What should be our priorities for 2007-2010? How can we continue to concentrate on raising the profile of the part that building services should play in climate change and still dedicate sufficient effort to our core tasks of providing members with the competence and information systems to assist them to do their jobs?

I am proud of what CIBSE has achieved and its powerful voice in the growing and crucial debate. What I hope we will achieve is hard action based on hard numbers. A major part of our task will be to impart some recognition of the value of hard data to our clients and the world at large. The accountants have had no trouble in making the argument, but today is the age of the building services engineer. We must do the talking.
