Embodying good practice C


uts, cuts and more cuts. Inevitably our news pages are full of such financial doom and gloom. And this is even before we know the details of


the full impact of last month’s Emergency Budget from the new coalition government in the UK, which plans to slash the spending of Whitehall departments and freeze council taxes. But, despite these ongoing pressures, the industry continues to teem with good practice and innovative engineering solutions. For example, our two features on ‘embodied carbon’, starting on page 31, highlight the importance of giving future generations an enduring legacy – not just in terms of sustainable buildings but by providing structures that will last and will also provide flexibility of use. As David Telford of hurleypalmerflatt argues, we need to ‘design-in flexibility in use’ to future- proof our buildings to cope with new and different technologies, and changes in their operation. In tandem with this approach, it is also important to make extensive use of passive techniques, so that we do not become overreliant on fitted technologies. Another aspect of this overreliance is that


it also potentially increases the proportion of carbon ‘embodied’ in our developments. Indeed, as property developer British Land has found (page 32), the more operationally efficient a building becomes, the higher the level of embodied carbon in its overall carbon footprint will be.

our developments; and we need to look to reduce the impact of the raw materials used – including their extraction, manufacture, assembly, installation, disassembly, deconstruction and/or decomposition (to borrow consultancy Deloitte’s definition of non-operational embodied carbon). This is certainly a tall order. But establishing a product’s true carbon footprint is something that the manufacturing sector is trying to get to grips with; and it is to British Land’s credit that it is attempting to incorporate this knowledge and make public the carbon footprint analysis of its whole property portfolio. The government is

promising to promote innovation via its proposed ‘green investment bank’. It remains to be seen whether this will unleash the coffers of the private sector, as ministers hope that it will. But we clearly do have the commitment of Energy and Climate Change Secretary Chris Huhne, a


Liberal Democrat, to a ‘green deal’ for consumers: the new Energy Bill will take forward the previous Labour government’s plans to encourage more energy efficient homes via a pay-as-you-save scheme. A ‘smart grid’ will also be developed for the supply and demand of electricity, according to the government.


Whatever the economic climate, the industry


must continue to seek to innovate, and to promote good practice. So let us know about your good engineering solutions – the Journal is always keen to share these with the wider industry.
