Civil engineers and architects in Switzerland have drawn up a plan to help reduce the country’s energy usage from 6.5 kW to 2 kW per person in line with its "2000 W Society" initiative.
Details are reported in the latest issue (165 ES4) of the ICE’s Engineering and Sustainability journal.
The 2000 W Society was launched in 1998 by the Swiss Federal Institute of Technology (ETH) in Zürich with the aim of reducing First-World energy consumption to the global average figure of 2 kW per person. No more than 25% of personal energy use (just 500 W) should come from burning fossil fuels.
Authors Adrin Fink and Roland Stulz of the society’s competence centre report on progress to date, which includes the launch of a new 2000 W construction standard in 2011 by Swiss Society of Engineers and Architects.
"The new standard sets the target values for embodied energy, operations energy and mobility to calculate a building’s energy footprint," says Fink.
The expansion project at Zurich’s Triemli hospital is one of the first projects of its kind to meet the new 2000 W specification. Stulz says "The hospital’s carbon dioxide emissions are expected to be reduced from 6000 t to 800 t per year."
He goes on to describe another successful project at the Science City-Campus at ETH Zürich where "A dynamic underground tank system will help to reduce carbon dioxide emission by at least 50%."
