Roennebaekhave II, Naestved 2005

The first Passive House in Denmark
Heat recovery, PV-modules, total economic optimisation,
Energy efficient windows, insulation, solar heating, heat pump with ground pipes
In the Danish part of the GREEN Catalogue project 8 out of 23 dwellings in Rønnebækhave II in Næstved were built according to the German “Passiv Haus” standard with a yearly heat consumption of only 15 kWh/m².
Equipped with a thick layer of insulation, passive house windows from Germany, counter flow heat recovery on ventilation air from EcoVent, 5 kWp PV-modules from Gaia Solar, a 28m² solar collector for domestic hot water and an earth heat system from the company IUT naturvarme.

Dalgasparken, Herning 2003

Ventilation with heat recovery, energy efficient windows, insulation, solar collector, PV-modules
Dalgasparken with 72 dwellings and a common room. Dalgasparken was built with focus on ventilation with heat recovery. Further the focus was on avoidance of cold bridges and also aimed at optimal airtightness. Measurements show a halving of the district heating costs on this basis alone. Further installation of 200 m² PV-modules to cover the electricity consumption for ventilators. The contractor was KPC Byg.

Hammerthor, Herning 2003

Ventilation with heat recovery, energy efficient windows, insulation, solar collector
A former cloth mill converted into 29 dwellings. The dwellings are built as low energy dwellings with several energy saving measures. The following has been implemented: ventilation with heat recovery with focus on airtightness, a high degree of heat recovery and a low electricity consumption for ventilators. Some of the rooms are heated with ventilation air exclusively. 7 kWp grid connected PV-modules are installed on the roof.

Havremarken, Frederiksberg 2002

PV-modules, heat recovery
In connection with the retrofit of the Havermarken 57,2 m², (5,8 kWP), PV-modules were installed in a row along the ridge of the roof. They supply 70 dwellings with electricity. The balance electricity, if any, is transmitted to the electricity grid.

Lauritz Sørensens Gård, Frederiksberg 2002

PV-modules, preheating of ventilation air
In connection with retrofit and alterations of attics into dwellings 15 m² PV-modules were installed for each stairway. The PV-modules were installed to form a so-called “Canadian Sun Wall”, where little holes cool the modules and thereby assist in preheating of the ventilation air to the dwellings. Each dwelling is temperature controlled.
