Intention and objectives of PhD project To develop a suggestion for a common European standard for future energy and CO 2 -neutral Active Houses. Developing knowledge about the holistic approach to integrating fresh air, plenty of daylight and healthy indoor climate into a sustainable way of living. Developing a method for integrating quantitative and qualitative parameters in developing buildings. 10. maj 2015 #5

Research Hypothesis Besides being energy neutral it is of great importance to human beings that their home is adapted into the surrounding environment and possess a high level of comfort, where daylight and fresh air are important parameters. 10. maj 2015 #6 Through development of a scientific method buildings can be defined and measured in accordance with both quantitative and qualitative values within the parameters Energy, Indoor Climate and Environment. By taking a holistic approach to future buildings on both quantitative and qualitative levels better buildings are created.

Design phase Calculated/preconditions Construction phase Measuring uninhabited Operation Phase Measuring inhabited Energy What effects are applied into the design to attract attention to energy? Is focus in creating a feeling of balance between energy and living in the building? Is the building created with attention to energy or has been subsequently applied? How is the experience in creating shape with energy objectives for the designer? How has the interdisciplinary collaboration been carried out? How is energy considered in relation to erecting the building? How is the interdisciplinary collaboration unfolded during construction? Measured energy when new? Experience of living a plus energy life? Experience of balanced relation between life and nature? Effect on everyday life? Awareness of human consumption? Experienced changes in position to nature and energy consumption? Infect on other people? Indoor Climate How is the daylight access integrated in the design? What factors are prioritised when designing the good indoor climate? Has the circumstances for creating been integrated in the process of designing the building? Immediate experience of daylight? Immediate experience of air quality? Experience of living a plus energy life? Experience of daylight effect on interior space? Experience of the influence of fresh air and daylight inside the building and different spaces? Environment How is the local building tradition integrated in the design? Adaptation to the surroundings and the landscape? Creating relation between place and architecture? Situation and location in landscape? Consideration to environment during construction phase? Experience of relations between indoors and out doors? Relation between environment and sustainable architecture? Experience of daylight inside and outside at the site?

Active House What is an Active House? 10. maj 2015 #12 ENERGY ENVIRONMENTINDOOR CLIMATE An Active House is CO 2 -neutral. By using renewable energy sources it has an exceptionally low level of energy consumption and procduces more energy than it concumes. An Active House has a healthy indoor climate, allowing. people to express themselves and live their lives in comfort. An Active House is designed, situated and constructed to interact with its environment.

Active House Design Parameters 1. A house that interacts with its environment 2. An open house that lets in nature 3. An intelligent house, controlled according to the weather and personal needs 4. An energy producing house 10. maj 2015 #13
