Sammanfattning
It has in previous research been shown that by performing energy and indoor climate
analyses in early-stage design, it may result in better performance of the building
in terms of energy use and indoor climate as well as resource efficiency.
A case study have been performed with a detailed development plan (DDP) of an
area in Gothenburg with an almost equal mix of residences and premises as the
reference case. Alternative design options of the site plan were considered such as
different type buildings, Window-to-Wall ratios (WWR) and the option of having
external corridors or not while maintaining similar total floor area.
The study showed a good correlation between the shape factor (SF) of the building
and the transmission losses, where a low SF is advised to minimize the energy use
for heating.
The purpose and goal of this Master’s thesis have been to investigate whether implementation
of Building Performance Simulations (BPS) could contribute in even
earlier stages than been studied before. In addition, it has been investigated if studies
of energy and daylight could be a positive supplement to current studies in the
DDP process.
Even though energy assessment could be challenging in early stage due to lack of
details, results from the case study in this master thesis shows that studying the
two aspects building shape (SF) and proportion of window in comparison to wall
area (WWR) could be a positive contribution when comparing different options in
the initial stage of building design. DDP:s shouldn’t encourage to building shapes
that in later stage can’t be implemented is a step against a more efficient building
design process. BPS in early stage could be one way towards reaching the European
Union (EU) goal; that all building constructed after 2020 shall be near zero energy
buildings.
