EnergyHome for Life produces more energy than it consumes. With an energy surplus of 9 Wh/m²/year, it takes approximately 40 years for the house to generate the same amount of energy that was used to produce its building materials. At that point, the house will have returned more to nature than it consumed. A solar heat pump and 7 m² solar collectors generate energy for heating and hot water, while 50 m² solar cells generate more electricity than the home consumes.

Indoor climateThe generous ceiling heights created by the pitched roofs allow air to circulate around the nursery’s rooms and the roof is scattered with Velux roof lights, which will automatically open and close to naturally ventilate the building. The roof lights are also a key element in introducing natural light into the nursery. The building is very compact and is designed as a triangle, with the two longest facades facing south east and south west.

In the new German regulation about energy performance of buildings EnEV 2009, the method to assess the equivalence of thermal bridges according to DIN 4108 Addendum 2 is rearranged. This should lead to a simplification of the evaluation of thermal bridges, but with the risk that thermal bridges are wrongly estimated. This article shows examples.

One of the documents that building designers like to use to take into account additional heat losses through thermal bridges is the Addendum 2 to DIN 4108. When details are planned and executed on the basis of this addendum, a flat rate value must be taken into account, avoiding complex calculations in accordance with European standards. However, problems occur especially when the actual details plans are not in accordance with those of the addendum. This book gives the basis for a proof of equivalence with the latest edition of DIN 4108 Addendum 2.

Organised by European Commission's Directorate General for Energy, the European Agency for Competitiveness and Innovation, the European Institutions, major energy actors and private companies, the EUSEW is the key annual event of the Sustainable Energy Europe Campaign and the reference point for sustainable energy issues in Europe. So far over 100 events are being organised in Brussels and all over Europe, and many more will come. Take a week to change tomorrow: come to the EU Sustainable Energy Week 2010 and you will enter the European network of best energy solutions.
