Development of system solutions for energy-extensive building envelope renovation of existing buildings and the demonstration on 3 typical detached houses from the perod 1960 - 1980

 The developed solutions and methods was demonstrated in three typical detached houses representing the 500,000 houses built in the period 1960-80 to show that the building envelope renovation can be performed with great aesthetic quality, a fair economy and high energy savings. Development of solutions to existing 1960/70 detached houses was a special focus area of the project and was used for the demonstration project. The houses have gradually become 30-50 years old and are facing renovation / replacement of basic building components: roof, windows and walls. They are popular and the supporting structures are generally in good condition so that demolition and new construction is not obvious. These homes represent a large energy saving potential and it will be crucial for any climate initiative that society promotes a response towards these buildings. Solutions for the 60/70' houses are in a considerable extent also relevant to buildings of different type and age
