Introduction Who am I? Interests • Techné / the meeting between science and phenomenology • Sustainability • Light / natural / artificial • Materiality / texture of material • Experience of space Monday, March 19, 2018 #4

Intention and objectives of Ph. D 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.

Quantitative measurements Data matrix Energy e. g. the measured solar thermal energy production [Window. Master measured values] Indoor climate e. g. measured lighting level [How could this be measured? ] Environment e. g. site solar intensity [How could this be measured? ] Monday, March 19, 2018 #9

Qualitative measurements Data matrix Design phase Calculated/preconditions Energy Construction phase Measuring uninhabited Operation Phase Measuring inhabited • What effects are applied into the design to attract attention to energy? • How is energy considered in relation to erecting the building? • Experience of living a plus energy life? • 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? Indoor Climate • How is the interdisciplinary collaboration unfolded during construction? • Measured energy when new? • 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? • Immediate experience of daylight? • Experience of living a plus energy life? • What factors are prioritised when designing the good indoor climate? • Immediate experience of air quality? • Experience of daylight effect on interior space? • Has the circumstances for creating been integrated in the process of designing the building? • • Experience of the influence of fresh air and daylight inside the building and different spaces? • How is the local building tradition integrated in the design? • Situation and location in landscape? • Experience of relations between indoors and out doors? • Adaptation to the surroundings and the landscape? Environment • How is the daylight access integrated in the design? • Consideration to environment during construction phase? • Relation between environment and sustainable architecture? • Creating relation between place and architecture? Monday, March 19, 2018 • Experience of daylight inside and outside at the site? #10

Qualitative measurements Data matrix Energy e. g. the experience of living in a plus energy house? [Qualitative methods - Interview] Indoor climate e. g. experience of daylight effect on interior space? [How could this be measured? ] Environment e. g. experience of on site? [How could this be measured? ] Monday, March 19, 2018 #11

Active House What is an Active House? 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. Monday, March 19, 2018 INDOOR CLIMATE ENERGY ENVIRONMENT An Active House is designed, situated and constructed to interact with its environment. #12

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 Monday, March 19, 2018 #13
