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

Trondheim, Norway

• 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
