The goal of the work was to fi nd out the best performance of a closed wet cooling tower system combined with chilled ceiling, serving a residential building. The research method was building simulation combined with optimisation. IDA-ICE was used for simulation together with GenOpt optimisation...

Traditionally, the Finnish legislation have focused on energy use and especially on energy used for heating space in buildings. However, in many cases this does not lead to the optimal concept in respect to minimizing green house gases. This paper studies how CO₂ emission levels are affected by...

Typically the aim in the construction process is to calculate the energy, space and cost efficiency in the design phase. These factors’ influence on decision making extends to the whole building process. How these decisions affect the use of the building and user satisfaction as well as...

Current office buildings are becoming more and more energy efficient. In particular the importance of heating is decreasing, but the share of electricity use is increasing. When the CO₂ equivalent emissions are considered, the CO₂ emissions from embodied energy make up an important share of the...
