Energy efficient solar heated Church , Hol, Norway. 2007.

As part of a four year EU F5 Project, “BRITA in PuBs”, where 8 nations tried to energy retrofit
existing public buildings to reduce annual energy need by 50 %, Hol church near Geilo, in central Norway
managed also to reduce the need for bought energy by 50 % through insulation, energy use
control and solar thermal. The church is under the wings of the Antiquarian authorities.
The brief read : What can you do when you are not allowed to do anything visible on the church envelope.

 ”Europe’s most energy efficient commercial building”,
International Architectural Competition, Bjørvika, Oslo, Norway.
2006

The goal of the competition was to design a total of 20.000 m2 spread over maximum 17 storeys next to the new Opera in Oslo. In order to participate, the design had to document a maximum total energy need of 80 kWh/m2 per year. Most similar buildings that are already built have a need of three times that – between 200 and 300 kWh/m2 per year.
Our proposal – named EF.PODS - documented a need of only 25 – 30 kWh/m2 per year.

This is as close to a zero emission commercial building as it is possible to get.  The goal was reached through extensive energy efficiency measures, reasonably sized glassed areas, well proportioned massing, proper sunlight shading and night insulation of windows along with energy supply from solar thermal and solar electricity (PV)

The two winners, however, claimed approximately 80 kWh/m2 per year. One of these was control calculated to 80, the other to almost 200 kWh/m2 per year. A fierce debate as to ethics arose in the architect’s journal Arkitektnytt (www.arkitektnytt.no).
