25%Cars, boats, trains and airplanes account for approx 25% of the world’s energy consumption
40%Today, buildings account for 40% of the world’s energy consumption
100%In 2050 energy consumption in buildings will be equal to the total energy usage in the world today – if we don’t do anything

Powerhouse is a collaborative alliance on energy-positive buildings
We want to change how we cooperate in the building industry
All key competence in a project should be available from the beginning

An energy-positive building is a building which during its operational phase generates more energy than what was used for the production of building materials, its construction, operation and disposal
Form follows environmentA result of cross-functional cooperation through the entire value chain

• Climatic challenging due to energy consumption used for heating
• Climatic challenging due to solar energy production
• Lots of wind...• Broad access to sea water
Pri 1: Collaborating with the best in each field
Pri 2: Maximum reduction of energy demand
Pri 2: Produce energy on site
Pri 4: Motivated tenantry
• Energy-efficient volume
• Superisolated building structure
• Demand control on all technical facilities
• Hybrid ventilation with low energy consumption to fans
• Good daylight ratio = minimize energy for lighting
• Heat pump for energy efficient heating of the building
