“Fjordudsigten” is the name of these houses which means ‘The View of the Fjord’ in Danish. It is located on the west coast of Denmark and includes 80 terraced houses.
The houses are quite unique. They are designed after the ambitious Passive House Plus principles, which means the houses do not need much energy to be heated. In fact, the homes here produce more energy than they consume. The ultra-low energy buildings provide a high level of comfort, a healthy indoor climate, cheaper heating bills as well as they are more climate friendly than conventional construction.
“The view of the Fjord” is a leading example of how public housing can be built with a minimal CO2 footprint without exceeding the price and without compromising on quality, longevity and well-being. LCA calculations show that the homes have a CO2 emission of just 3.1 kg CO2e /m2 each year. It is 75% less than the requirements of the Danish building regulations.
By optimizing how we heat up the houses and keep it from leaking, we reduce the use of C02 heavy resources. The majority of the energy savings are an effect of the buildings design and construction. They have a compact building shape, quality insulation, high-efficiency mechanical systems, airtight construction and solar orientation of the high performance windows. The current residents achieve 63% energy savings compared to an average spending of houses of the same size in Denmark. In a time with high energy prices, these kinds of houses are super attractive.
Making nature an integrated part of the whole area was an important principle in the design process. That is why the buildings and existing nature merge in a way that gives the residents a feeling of being part of the nature that surrounds them. To make sure nature around the area is preserved and to climate-proof the buildings there are systems in place to transport fallen rain from the buildings to surrounding creaks and watery areas.

The Compact P is a ventilation and heating system that provides with ventilation, heat recovery and domestic hot water production. It ensures a daily renewal of the air by evacuating dust, odors and excess humidity for a healthy and pleasant indoor atmosphere. When it is hotter inside than outside the house, an integrated bypass lets fresh air in directly to cool down as much as possible without using additional energy.

Reasons for participating in the competition(s)
- The houses does not need much energy to be heated.it produces more energy than it consumes;
- The houses are more climate friendly than conventional construction;
- Rain water is running to a rain biotope, and from here to a brook, grey water runs to a central cleaning plant;
- Cross ventilation can be used in all rooms;
- The window surface temperature indicator shows comfort values on all major glacings. All U values better than comfort U values;
- Large south-facing windows with energy-efficient glass. Exploits solar heat and reduces heat loss;
- Bright and solar-heated rooms with good comfort and indoor climate both in summer and winter;
- Solar cells on roofs produce energy;
- Excess solar energy is used to heat domestic hot water.
