Danish participation in new IEA task on zero energy buidlings (ZEB)
The project is an international IEA – cooperation project, which will contribute to the goal of making Denmark one of the leading countries regarding development of buildings with a very low use of energy. Valuable inspiration and knowledge from foreign experiences will help solve any problems that could come in working with the development of low energy floor buildings.
The project will help to position Denmark among the worlds leading countries in development of very low energy buildings. At the same time it will be possible to gain important knowledge on very low energy building developments in other countries for the benefit of the Danish building industry in general and for the BOLIG+ project in particular. It will be possible to discuss the BOLIG+ projects and dogmas among the leading international experts and gain valuable input to overcome possible problems in the design process of the multi-family BOLIG+ project. Furthermore, the problems and possibilities for the other BOLIG+ scaling levels (densely build, low buildings and detatched houses) will be a natural topic for the IEA (International Energy Agency) ZEB collaboration. Results from the project will go directly to the institutions and companies involved in the BOLIG+ contest and indirectly to the Danish building industry as articles in relevant magazines. Results from the PhD study will be reported in reports and articles in relevant journals. The work programme of the Danish project will follow the rolling project planning for the IEA project. The BOLIG+ dogmas: Energy neutrality – including electricity for low energy domestic appliances; Intelligent and user friendly; Good and healthy indoor climate; Flexible in daily use and over time; Adapted to local context and of high architectural value.
The project has given valuable insight in experiences with energy neutral buildings (Net ZEB) all over the world and the challenges connected to establishing such buildings. In the project it has been demonstrated that it is possible to establish buildings that on an annual basis do not consume more energy for heating, cooling, domestic hot water and operation of the building installations plus the users electricity usage than can be produced by renewable energy sources on the building surface or the building site. The buildings analysed were all, except one, connected to the national energy grids and utilises thus the grid as storage for energy in periods with abundant renewable energy to take it back in other periods. The problems about quality and usability of the exchanged energy has been analysed in detail.
In the project a tool for evaluation tool for Net ZEB have been established, taking into account exchange of energy with the energy grids. Additionally, a number of example books have been published as outcomes from the project. Information about publications can be found at: http://www.iea-shc.org/
