Oslo studio [You must be registered and logged in to see this link.] and [You must be registered and logged in to see this link.] of Austin, Texas, have designed a green office building in response to the UN Framework Convention on Climate Change ([You must be registered and logged in to see this link.]) held in Copenhagen earlier this month.

The design, called Skagen ØKOntor, features individually-controlled
insulated shutters, allowing the window area to be altered between 20
and 60% of the facade.

These shutters would have LED lights on their inside surfaces to
mimic daylight during the longer hours of darkness in winter months.

The project was designed for a specific site in Skagen, Denmark, and would make use of sea water for heating and cooling.

Here’s some more information from the architects:

VARIOUS ARCHITECTS DESIGN NORWAY’S MOST EFFICIENT OFFICE BUILDING
To demonstrate our commitment to the environment and support for the
COP15 Climate Change Conference in Copenhagen, Various Architects AS of
Oslo, Norway together with engineers from Ramboll UK in Bristol and
Pollen Architecture in Austin, Tx have designed the Skagen ØKOffice
(“eco-office”) as a model for sustainable low-energy/low embedded
carbon office buildings that are suited to the nordic climate. With a
calculated net energy consumption of 72 kWhr/m2/yr* the ØKOntor is the
most sustainable office building currently planned in Norway.
“We wanted to present the developer with an environmentally friendly
alternative for their site that was both innovative and buildable. This
design is site specific, but it contains many concepts that can be
applied elsewhere in the Nordic countries.” – Jim Dodson, Partner at
Various Architects.

The building’s wooden facade of individually operable insulated
shutters is it’s most visible and dynamic feature. Floor height
shutters can be opened during the day to allow in daylight and passive
solar heat, or closed after sunset on cold days for added insulation.
The shutters can transform the facade from 60% to 20% window area.

The inside surface of the shutters are tiled with LED lights to
produce artificial daylight during the dark winter months to help
provide a well-lit and healthy working environment year round. The
insulated shutters are calculated to provide an additional 15% savings
on heating yearly.

The natural resources of the seafront site are all carefully
utilized by the design. 4 Quiet Revolution wind turbines on the roof
provide 24.000 kWhr of clean energy (10% of the building’s energy
demand). The windy and often overcast weather on the norwegian west
coast, combined with long dark winter nights made wind a more efficient
alternative to solar panels in this case.

The sun is controlled for solar shading and passive heat in the west
facing atrium space, and through the many south facing windows. Sea
water is used as an energy source for both heating and cooling via
water cooled heat pumps and sea water free cooling. This, coupled with
high efficiency air heat recovery, demand led controls, and high levels
of thermal insulation have significantly reduced the thermal plant
demand.

Natural ventilation is possible for most of the year, with cooling
through refrigeration only necessary when sea water temperatures are at
their peak (no more than 4-8 weeks a year). Green roof surfaces collect
and filter the area’s prodigious rainfall in rooftop water tanks for
use in low-water fixtures and fittings, reducing the need to waste
treated water.

Low embodied carbon materials were chosen where possible to reduce
the project’s overall CO2 footprint. A structural system of
cross-laminated timber (CLT) panel walls and floors was chosen for
being locally sourced with a high level of carbon sequestration. CLT
represents a significant reduction in embodied CO2 compared to a
traditional concrete or steel frame.

The building exterior and insulated shutters are clad in Kebony, a
norwegian wood product that is sustainable, low-maintenance, and
suitable for the exposed seaside climate.

The newly implemented TEC2007 norwegian building directive requires
the energy marking of all new buildings. From 2010 office buildings
have a maximum allowable energy use of 165 kWh/m2/year (Energy grade
C), while a typical office building today uses around 270 kWh/m2/year.
At 72 kWh/m2/yr the ØKOffice would achieve a Grade A energy rating,
less than half the required maximum.


Norway does not have a Passivehaus certification system yet, but the
ØKOffice complies with the certification principals of heat recovery,
excellent airtightness, summer solar shading, high levels of thermal
insulation, using useful passive solar/equipment heat gains and a net
energy use of less than 75kWh/m2/yr.

Various Architects and Ramboll believe that the ØKOffice project
demonstrates that architects, engineers, and developers of new office
buildings should push harder to develop highly energy efficient
buildings with a zero net-carbon construction.

We should not accept the minimum reductions required by law as
standards, but should see them as a challenge to do better. Good luck
to the COP15 representatives.
