3 Denmark's largest development project within construction with no heating system will show the way for buildings with passive heating in Denmark In the course of 2007, the first ground will be broken on Denmark s largest development project to date of single-family houses with no heating systems and with an optimal indoor climate. The aim of the project is to spread knowledge about buildings with passive heating and to set the agenda both for future construction and for the energy policy debate. The project will involve a large number of stakeholders, so it will also operate as a learning process. must inspire and be living examples of how perfectly ordinary single-family houses can be built using the passive heating concept. contain the answers to current energy and environmental issues: The energy consumption for heating is close to zero The contribution to carbon emissions is therefore very low Home comfort, including indoor climate and low allergen content, is high therefore have the potential to shape the concept of future Danish single-family houses, focusing on increased comfort and environmental sustainability.

4 in the Skibet area Saint Gobain Isover a/s is the instigator of the project which builds on international experience Behind the initiative is Saint Gobain Isover a/s. In its capacity as the world s leading producer of insulation materials, the ISOVER group has a natural interest in promoting knowledge of how to reduce a building s energy consumption. At international level, ISOVER is an active contributor to many projects using passive heating. Know-how and experience are harnessed together in the concept of the ISOVER MultiComfort House. This knowledge is now being transferred to Denmark, where the aim is to build up a network of architects, contractors, consultants, standard house builders and manufacturers of building materials who will work to spread the passive house concept. The project in the Skibet area is based on the company A/S, which is jointly owned by Zeta Invest A/S and Middelfart Sparekasse (Savings Bank). Both have sound experience in the housing market. The houses will be designed and built in accordance with Danish building practice. Sizes are expected to vary between 170 and 250 square metres. Construction is expected to start in the third quarter of 2007, and the houses will be put up for sale at the end of the exhibition in the third quarter of will promote Danish construction to the world elite within energy-efficient construction while respecting Danish building practice

5 The project is a development of 10 single-family houses grouped in the attractive Skibet area west of Vejle.

6 The house without radiators It sounds like mumbo jumbo - but the fact is that are built exclusively to wellknown principles It is hard to conceive of a house without radiators. After all, they have always been part of our houses. But confound our expectations. There is no heating system, no radiators, but otherwise there is nothing out of the ordinary. What is new is that we are using our knowledge of well-known principles and the interaction between the individual structural elements to construct a house which uses almost no energy for heating, and has a fantastically good indoor climate. mm in walls and 450 mm in floors and roof. There must be no cold bridges. Windows help control the temperature indoors In winter, when additional heat is needed, the sun will hit the window panes. In summer, they must not be directly affected by the sun. Large glazed panels should therefore face south but be recessed under an overhang, so that only the low winter sun hits them. The window frames must also be thermally insulating. More thermal insulation Passive heating works like a thermos flask, in that the more heat is retained, the less energy needs to be used for generating new heat. This means that the insulation has to be thicker than normal, about 300 Heat recovery and controlled ventilation The heat in the house is re-used with the aid of heat recovery and controlled ventilation. To be able to use this principle fully, it is necessary for the house to be completely airtight.

8 Healthy, fresh indoor climate A house with passive heating is always warm and comfortable A constant temperature all year round of, for example, 22 C, fresh air in all rooms at all times and constant low relative humidity: This will be a reality in the. Well-insulated and airtight construction and energyefficient windows mean amongst much else that an even surface temperature is achieved throughout the room and that it is possible to sit near the window all year round and enjoy the view and daylight without the discomfort of draughts or cold. At the same time, the ventilation system ensures that the air in all rooms is continuously replaced by fresh air from outside. Controlled ventilation also has a number of advantages for the indoor climate: dust, pollen and particles are filtered out of the air, and the automatic extraction reduces moisture and dust, so you do not have to spend time every day airing the house, but can open a window when it suits you. In a house with passive heating there is also less noise pollution from the surroundings as the efficient thermal insulation and good windows also provide better sound insulation.

9 The future energy-efficient and environmentally sound single-family house will inspire us to save energy Energy consumption is rising. Scientists are worried. Increasing carbon emissions threaten to change our climate. Politicians are also worried. They have signed the Kyoto Protocol and are following up with several initiatives. But how will we achieve the agreed aims? The answer is blowing in the wind, but one thing is certain: we must all help. According to Denmark s Energy Strategy 2025, Danes must save up to three times as much energy as we have done so far through special initiatives. It will not merely be difficult. It calls for a change of attitude and for proactive action. Around 40 per cent of our energy is used in houses. Therefore, it is crucial to make changes at home. The in the Skibet area are seen as a beacon. They will let the Danish construction industry showcase its contribution to meeting the aims of the Kyoto Protocol. Knowledge and expertise concentrated in a dynamic enterprise, a nucleus in which for the first time technologies and methods have the opportunity to work together on a large scale and be part of the house without radiators. also point the way for national and local politicians. Here they can see a whole housing development with no heating systems, and get an idea of the route we can take to protect the environment for the future. They can be inspired and include the concept in legislation and local planning. are a vision of the future for single-family houses, helping to reduce carbon emissions, cutting almost all heating costs and providing an optimal indoor climate.

10 The beginning of a new era The are expected to be ready in the third quarter of 2008 The coming two years will confound our usual expectations about energy consumption of single-family houses. During this period, the will be built in the Skibet area without heating systems in a collaboration between Danish architects, consultant engineers, standard house builders and manufacturers of building materials. The parties will collaborate throughout the project and form networks. Development and learning processes will characterise the process, and entirely new methods and market opportunities may arise. 10 different houses The project imposes special requirements for active participation. Therefore, the manufacturers/contractors who are to build the houses will be selected by pre-qualification. There will be 10 different houses resembling those which Danes prefer today. They will be built in accordance with Danish building practice. Attractive plots The total of 10 houses will be built in an attractive area in Skibet west of Vejle where the rural surroundings with hills and lakes might have been created for a type of house that protects the environment. The development is 500 metres from a school and 6 km from Vejle centre. Milestones in the project 1st quarter 2007: Plots purchased. 2nd quarter 2007: Pre-qualification. 3rd quarter 2007: Houses built. 1st quarter 2008: Shells exhibited focusing on structures and details. 2nd quarter 2008: Houses completed. 3rd quarter 2008: Houses exhibited and sold. 10
