2. 25%
Cars, boats, trains and
airplanes account for
approx 25% of the world’s
energy consumption

3. 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

4. The founders: ZERO, environmental organization
Skanska, developers Entra, property developers
Snøhetta, architects Hydro, aluminium company

5. 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

6. 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

7. Form follows environment
A result of cross-functional cooperation through the entire value chain

8. 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

9. 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

10. • 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
