Green Options

Under recommendations from the UK Green Building Council, otters could return to urban rivers, bats could roost under bridges, swifts could flock to office blocks and peregrine falcons soar above cathedrals. Written by Felicity Carus and shared via the Guardian Environment Network.

What do the Westfield shopping centre, Canary Wharf and a Victorian museum have in common? They are all at the vanguard of a move to encourage biodiversity in buildings that could take on an unprecedented scale if guidelines published today are adopted.

A groundbreaking study has proved that man-made light sources can change natural light cycles, triggering abnormal animal behavior that often leads to injury and even death.

The study, published in the journal Frontiers in Ecology and the Environment, confirms that polarized light pollution can cause confusion in creatures that rely on light ‘cues’ to navigate through their environment, with many animals also thrown off course by light reflecting from buildings.

Buildings, according to calculations done by Architecture 2030, are responsible for nearly half of the total energy consumption in the United States. And 76 percent of the electricity generated in this country goes to the Building Sector. So while there are a range of steps that need to be taken in moving toward a more sustainable lifestyle, Buildings, and the energy they consume, need to be at the forefront of any considerations when moving toward greater sustainability.

Saving energy in buildings is both one of the easiest things that can be done, as well as one of the hardest. The principles for creating a building that needs less energy and operates more efficiently are well known. Most building technology is fairly basic and easy for even non-experts to understand. This makes it simple. We don’t have to wait for expensive, high tech solutions (though they can contribute greatly and will provide new flexibility and compelling possibilities for building better buildings in the future). Heavily insulated buildings can be easily constructed with readily available and well known technology. Adding more insulation to walls is easy, though there is a cost. Consumers and building owners need to become more aware of the long term costs of operating a building, and give consideration to more than just the initial construction costs. And overcoming economic considerations and taking a long-term view is the hard part.

The city of the future is not going to be a Jetson-esque collection of bubbles in the air, or towers connected by monorails, or any other radical vision. The city of the future will be more like that in Blade Runner, mostly recognizably familiar older buildings. Most of the city of the future has already been built and is standing. Certainly new buildings will
