IntroductionWho am I?

Interests

• Techné

/ the meeting between science and phenomenology

• Sustainability

• Light / natural / artificial

• Materiality / texture of material

• Experience of space


Intention and objectives of PhD project

• To develop a suggestion for a common European standard for future energy and CO2-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.


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.


• 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.

Active HouseWhat is an Active House?


An Active House is CO2-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 HouseDesign 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
