Abstract [en]

Singapore is a country that is currently highly dependent on import of oil and gas. In order to be able to shift into a more sustainable energy system, Singapore is investing in research regarding different technologies and systems so as to establish more sustainable energy solutions. Seeing how air-conditioning accounts for approximately 30 % of Singapore’s total energy consumption, a feasibility study is being conducted on whether an integrated system using a thermally active building system (TABS) and desiccant evaporative cooling system (DECS) can replace the air-conditioning system. The question which is to be discussed in this thesis is whether solar and wind power can be financially feasible in Singapore and if they can be utilized in order to power the integrated system.


The approaching model consists of a financial feasibility study of the different technologies and a theoretical test-bedding, where the suitability of the technologies to power the TABS and DECS is tested. The financial feasibility is estimated by calculating the payback period and using the net present value method. A model designed in a digital modeling software is used for the test-bedding. Measurements from a local weather station are used for estimating the solar radiance and wind speeds in Singapore. The results show that solar PV panels could be feasible in Singapore but that technological improvements as well as governmental subsidies are needed in order to make it profitable enough to attract investors. As for wind power, the wind conditions are not favorable enough, in terms of wind speed and wind frequencies, for small wind turbines that currently exist on the market to be able generate enough electricity to make the investment somewhat feasible. Solar thermal collectors and solar PV are given certain conditions suitable for powering the TABS and DECS.
