To be truly rooted in my final degree project, I decided to go back to something that fascinated me as a child; To live among the trees. I remember trees standing out as individuals, as landmarks, and as architecture. Cultures all around the world displays importance in their relationship to trees, be it a source for shelter, food, symbolic references or playing as a child. This project explores the actual building process, when constructing something in a living tree. It turns into both a physical and mental challange. This project is divided into two main modes; (1) a research activity, and (2) a building action. The method is almost an intuitive one, being in the tree, at the construction site, as I both come up with design concepts, metaphores and physical solutions for the project. The conclusions are both sketches and real solutions as much as the actual final tree house experience. The site is situated about 10 km south of Uppsala, Sweden. / För att ha en tydlig grund i mitt sista projekt i utbildningen, valde jag att gå tillbaka till något som fascinerade mig som barn, att bo bland trädtopparna. Jag minns träd som individer, som landmärken och som arkitektur i sig själva. I alla kulturer runt planeten finns tydliga relationer till träden, om det är en källa för mat och husrum, symboliken i religioner, och lekfullheten hos barn. Det här projektet utforskar själva byggnadsprocessen, genom att bygga i ett levande träd. Det blir både en fysisk och en mental utmaning. Projektets process har fortgått i två huvudsakliga grenar, (1) en forskingsaktivitet, och (2) ett konstruktionsexperiment. Metoden har varit nästan intuitiv, varandet i naturen och i trädet har fått styra både konstruktionen och designidéer. Slutprodukten åär både skisser, och riktiga fysiska lösningar, samt erfarenheten av att vara i själva trädhuset. Platsen för bygganden ligger ungefär 10 km söder om Uppsal, Sverige.

This study addresses the use of a Solar blind system (SBS) instead of ordinary glass used on windows of buildings. To investigate the effects of using an SBS for electricity energy generation a fictitious wooden house as a prototype, a real building needed to be constructed. The purpose of experimental studies is to measure the effect and asses the performance by examining the optimal angle of inclination and evaluating the profitability of SBS. To calculate the electricity energy generation by it is then expected that general renovations of a building will be used in the system. To perform the different scenario for each inclination angle, the simulation software PVsyst was used where the measurements are validated according to the simulation results to confirm that models are suitable and which inclination angles produced the most electricity. After the validation process, a financial assessment, and an annual electricity production of the system for a fictitious building where SBS is applied were performed. The result for the annual electricity production at different angles of inclination turned out to be 2457 kWh/year at 30, 2235 kWh/year at 60   and 1781 kWh/year at 90 . The optimal angle of inclination was 30  , which also has the highest electricity production compared to the other angles. Electricity production does not differ much with the inclination angle of 60. The simulation for the annual electricity production was examined for ten windows in opposite directions. The investment cost for the use of SBS was extraordinarily high, landing at 28,120 SEK/kW. The reason for this high investment cost is that it includes high material costs and that the area for SBS systems is low, which is 1,696 m². The reason is that the low area in m² leads to a lower electricity generation and the higher the area m² leads to higher electricity generation, which turns into affecting the profitability and electricity production.
