[intro]

The vision of the project is to design a sustainable housing project that will

fulfil zero energy as well as aesthetical and functional requirements. The

future housing complex must encourage healthy lifestyle and conscious ap-

proach to the nature and surroundings. The goal is to create a synergy be-

tween sustainable strategies such as: cultural, social, solar and zero energy.

- Optimize passive gains- Compactness

Optimize the envelope- Reduce losses through the building

- Create an air tight envelope- Effective windows

- Minimize thermal bridges- Increase insulation

Active gains- Energy production, pv-cells

- Use of heat recovery
