Counting zero carbon angels I am sure readers will applaud Messrs Jones and Shaw in their wish for government schemes to use a single carbon emission factor for the grid (Opinion, August Journal, page 12). There is already too much micro-bureaucracy around that is swamping green enthusiasm when it comes to implementation. But it can hardly be justified to seek an answer to one part in 500 (‘0.591,0.568,0.543 or maybe even 0.517?’) for application in an industry that is hard-pressed to get out turn energy consumption to match design within one part in 10. Other regulatory fudge factors like ‘good quality combined heat and power’ usually call a halt at two significant figures or less. Looks like it’s a choice between 0.6 or 0.5, giving the added advantage that less time is wasted counting the number of zero carbon angels on a pin. Prof David Fisk CB
Better assisted living advice Regarding your News in Brief on ‘Assisted living advice’ (August Journal, page 8), designers of buildings and systems for assisted living probably would find the FAST (Foundation for Assistive Technology) supplementary report at

MANUFACTURER’S VIEWPOINT
Join the debate on how we reach a zero carbon future, writes Martin Fahey of Mitsubishi Electric, sponsor of this column
Mitsubishi Electric recently launched phase
two of its Green Gateway philosophy, which aims to shape the UK’s energy future by focusing attention on energy use in the built environment, to help tackle the triple challenges of climate change, fuel security and rising fuel costs. Before anyone dismisses
this as mere ‘greenwash’ it is worth thinking about the fact that around 75% of existing buildings will still be in use for the next 50 years – so, to a large degree, the future is already built.
The UK government is committed to the most far-reaching and long-term emission reduction targets in the world (80% reduction by 2050, based upon 1990 levels), and buildings – the largest contributors – have to play their part. The answer has to be to work with what we’ve got by improving the efficiency of existing buildings and using advanced renewable energy systems to ensure we minimise consumption. We have got to get every household, business and commercial premises thinking along the lines of being lean, mean and green. What we need is a debate on how emissions from existing
buildings can be drastically lowered if the nation is to achieve the stated long term emissions targets. As a major supplier of
building services equipment, Mitsubishi is trying to leverage the sphere of influence we have within our market and focus attention on the important role that heating, cooling, ventilation and power
We have got to get every household and business thinking lean, mean and green
generating solutions will play in helping to provide a sustainable future for Britain’s buildings. And we are not alone, as
others realise that it is only by working together that we will be able to find answers on the scale needed At our launch on 20 September at the Building Centre in London, Paul King, chief executive of the UK Green Building Council said: ‘This debate that Mitsubishi Electric is trying to start is exactly what the World Green Building Week

is all about. We need everyone involved, from individual architects and plumbing installers, through homeowners and landlords, to major corporations and businesses to join the debate and question the energy they use, and then find ways of reducing it.’ As a company, Mitsubishi
Electric has placed the drive for energy efficiency, reduced carbon emissions and the integration of renewable energy technologies, at the heart of its business; it has always been willing to talk to others, even competing technology providers, in order to achieve the right solution for any individual building. As buildings are the largest consumers of energy, they have to be become more efficient and, where possible, incorporate renewable energy so that our demand for fossil fuel is reduced and we can develop a level of energy independence.
