1	Retrofitting a Single-family Home with Increased Use of Renewable Energy Ma, Chenwen January 2017 (has links) Buildings account for up to 40% of the total energy use in the world. Directives from the European Union have pointed out the significance of increasing the energy efficiency in buildings. New regulation in countries like Sweden has established that new buildings should fulfil regulations of Nearly Zero Energy Buildings (NZEB), providing the opportunity for renewable energy technologies to achieve these goals. In this paper, the retrofitting potential of renewable energy technologies for a single-family home in Sweden was investigated.The present work studied the characteristics of several renewable energy technologies and their applications for a single-family home in Sweden, including biomass, solar photovoltaics, solar thermal, heat pump, and small-scale wind turbine. Three renewable energy technologies (solar thermal, heat pump and small-scale wind turbine) and one renovation method (window) were selected to investigate. The analysis was made of the current energy use and the potential energy (and cost) savings from each retrofitting of these facilities by means of simulation models using IDA ICE software. The study results show that the proposed renewable energy technologies are technically feasible and economically viable as a source of alternative renewable energy in order to produce clean energy and reduce electricity bills for an electric-heated single-family home located in Sweden. Moreover, the combined retrofitting scheme consist of solar thermal system and window renovation was also proposed and explored. As a result the energy performance of the single-family home would satisfy the nearly-zero energy building requirements and thermal comfort could be maintained at an acceptable level. retrofitting nearly zero energy building single-family home renewable energy technologies energy saving energy performance solar thermal system heat pump small-scale wind turbine window renovation Building Technologies Husbyggnad
2	Observations of a Window Frame : About the Importance of a Forgotten Detail Nilsson, Oskar January 2022 (has links) Due to the geographical location, the amount of daylight in Sweden varies greatly during the year - the lack of light is part of our everyday life. Regardless of the season, the sun’s position gives a light that seems to fall from the side, it kind of drags itself in through the windows. As a result, it is easily influenced by the surroundings. All the edges, corners and profiles that stand in the way create an endless variety of shades. Given these conditions, it is a good reason to devote time to the detailing of all the parts of a window. In this master’s project, I am directing my gaze towards the window frame and more specifically towards the framework’s profiling. By observing the shape and the color language of different profiles, the perceived contrast between light and shades is noticed and interpreted into new. Based on the qualities of the Nordic light, this project hopes to clarify and show with concrete examples why decision-making around the window frame is crucial for how we perceive the incident light. Relatively small differences in profiling create a large effect in contrasts, I find, and consequently, a more complex window profile enhances the character of the window and the incident light. This project is about looking at something specific, to observe and to explain what already is there. window window frame interior architecture spatial design daylight shadow color perception window renovation aesthetics fönster fönsterkarm inredningsarkitektur rumslig formgivning dagsljus skugga färg kulör renovering estetik Architecture Arkitektur Design Design
