Abstract: This thesis analyzes energy and cost efficient single dwellings for Peab. It is our ambition that an energy efficient alternative to traditional Peab construction methods and that this will be the continuation of the thesis specific case Oxled in Partille. A series of buildings have been proposed in the thesis, however the design of the buildings have rather been a method of investigation than a result. Instead, the main focus has been to gain knowledge in energyefficient building techniques. It is essential to adjust the design to the specific concrete project. In order to test the building system and the design, energy simulations have been conducted in Derob where the Swedish passive house requirements have been a guideline. The final model is a building that fulfils the passive house requirements. The model costs 5 % more than a project that has been planed for 2010 by Peab according to quantitative surveying however the difference in heating costs makes the investment profitable. A deeper analysis of the combination of air duct and mechanical extraction ventilation is conducted. As the air heat exchanger often is considered good enough in Sweden, air ducts are rare in Swedish passive houses. However in Germany, Austria and Switzerland the air duct, often in combination with an air heat exchanger, is standard. According to calculations in the thesis, the model with an air duct will consume close to the same amount of energy as the same model with an air heat exchanger, but the indoor climate will be improved. The model is designed as a passive house, either with air duct or heat exchanger.In connection with this analysis humidity is investigated in an energy perspective. It is displayed that it is possible to save energy by considering production of humidity as lost energy. We that write this thesis are architecture and a civil engineering student; together we have taken a broad perspective on energy efficiency and have investigated numerous cost and energy saving solutions. It has not been possible to include all of these solutions in the final model. They have instead been investigated as side tracks in the thesis. In order to give the thesis a base numerous actors in the Swedish building industry have been contacted and many interviews and study visits have been made. Other important parts have been Chalmers Architecture, the institution of Design for Sustainable Development, the institution Build physics, Peab Sweden and Passivhuscentrum.
