Intep to present two posters on the 2,000-Watt Society

Building research with view to energy and ecology

On September 4th and 5th, 2014, brenet, a network of building services and renewable energy experts, will host its 18th status seminar in Zurich, Switzerland, presenting and discussing current research projects on sufficiency, efficiency and consistency.

The 2,000-Watt Society concept and urban planning

Intep manager Daniel Kellenberger and Intep consultant Katrin Victor will contribute a poster presenting the results of a research project dedicated to the “analysis of the 2,000-Watt Society concept in the urban planning process” and funded by Switzerland’s Energy Department. The research team (Planar and rundum mobil) is headed by Intep and is complemented by a support team. Three workshops will be organized to allow a panel of experts to provide input. The project is completed by a structured analysis of urban planning processes, focussing on those aspects which have an impact on the 2,000-Watt targets such as building densification, mixed-use development and the conservation of resources. Evaluating these aspects using existing building, district and municipality evaluation tools will determine whether a new tool or the refinement of an existing tool can help achieve the 2,000-Watt targets.

Internationalization of the SIA energy efficiency guidelines
In a poster session, to be held on Friday, September 5th, former Intep intern Dominik Kaspar will present the results of his Mather’s thesis. He has developed a calculation model for the application of SIA’s energy efficiency guidelines to national contexts, thus allowing different countries to determine their specific targets for homes, offices and schools. The model was first applied to a building in Germany. This example illustrates how the methodology of the Swiss guidelines can be used in other countries while showing that future energy balances can no longer be based on a building’s construction and operating energy alone. In order to meet the 2,000-Watt targets, the building’s location and the resulting energy use for mobility must be factored in when determining the building’s overall energy performance.
