Udvikling af typehuse i lavenergiklasse 1

Share this Post:
This report describes two typehouses that fulfill the requirements to low energy class 1 buildings according to Danish Building Regulations. The low energy class 1 typehouses have been developed from standard typehouses as built today, i.e. houses that fulfill the minimum requirements regarding total energy consumption according to Danish Building Regulations. Through detailed calculations/simulations and in cooperation with the typehouse producers, i.e. Eurodan Huse A/S og Hjem A/S, new typehouse solutions that fulfil the requirements to low energy class 1 buildings have been developed. The report is split into two main chapters, one for each of the two typehouse solutions. Each main chapter starts with a detailed description of the original typehouse solution, and firstly detailed calculations of all heat loss coefficients for the constructions including windows and doors are carried out. Then the transmission areas are determined for each building construction, and finally a detailed description of the heating and ventilation systems are given , with emphasis on the parts relevant in the calculation of the total energy consumption for the building. All the calculated results are then entered into the program BE06, and a calculation of the total energy consumption is carried out. These calculations show that both original typehouses fulfill the minimum requirements in the Danish Building Regulations. The following section details the process of reducing the total energy consumption for the typehouses. The reduction of the total energy consumption is achieved with a starting point in two exam projects that has analyzed the respective original typehouse solutions, and through economical optmization processes, developed a series of proposals for reducing the total energy consumption. The final low energy class 1 solutions are determined by starting from the two exam projects and in cooperation with the two typehouse producers determining the final solutions. In the final section of each of the main chapters, a detailed description of the low energy class 1 solutions are given, detailed calculations of heat loss coefficients are performed, new transmission areas are determined and a detailed description of the heating and ventilation systems are given. Finally a new BE06 calculation for the new typehouses are performed, and these calculations show that both new houses fulfill the requirements to low energy class 1 buildings according to the Danish Building Regulations. The report is concluded with a summary of the project results, and it is concluded that the project aim has been achieved, as two new typehouses with a total energy consumption that fulfil the requierements to low energy class 1 buidlings according to the Building Regulations have been developed.
