Sustainability and Environment
Most of my work has centred on the belief that, though
difficult to achieve in absolute terms, sustainability is measurable and easy
to define conceptually. It is not essentially a ‘buzz-word’ or the
ephemeral concept it is sometimes claimed to be.
At its heart sustainability relates to systems, resource
flows through them and carrying capacity. Such systems can be defined at the
level of the individual home, community, region or globally. It is often the
difficulty of defining the boundaries of the system which create the problems
of assessing sustainability. How strictly autonomous as an independent system
does a ‘zero-carbon’ house have to be, for example?
People are at the centre of all drives towards greater
sustainability and it is the relationship between people and their environments
that forms the core of my work. People may be motivated by the spectre of
global warming. Yet people throng to join the protests about petrol prices,
virtually unchanged in real terms since 30 years ago, when environmental
concerns scarcely showed up on the political radar.
We have improved the energy efficiency of our new buildings
over this same period by a huge amount. Yet energy consumption per household
has risen – albeit slightly – whilst the average number of people
per household has fallen by 20%. It is our behaviour, how we choose to live and
the way we use our houses which has perhaps the greatest impact on this aspect
of their sustainability.
People hold the key to improving sustainability and studying
the relationship between people and their environment is essential in achieving
sustainability gains.
