Udvikling af typehuse i lavenergiklasse 1
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.
