Two residential buildings with 115 apartments located in Gothenburg, Sweden, is renovated as a passive house (according to German definition) and also it has obtained the Green Building certification. Hamnhuset in Gothenburg is one of Sweden’s largest passive buildings, refurbished in 2008 based on a design by White Arkitekter AB and and built with these design concepts: reaching a quarter of regular heating demand, emitting a quarter of typical CO2 emissions, creating a very good indoor environment and making extensive simulations and LCC-calc, and having reasonable rents for tenants.
Information about Hamnhuset.
An energy-efficient apartment building, non-traditional heating system. Long-term thinking profitable already today! Details about the building process, design planning, LCC analysis and energy-efficient buildings. The report also describes the technical solutions for walls, windows, ventilation, heating, water consumption, and energy-efficient design.
Evaluation from SBUF.
Hamnhuset in Gothenburg works well. Temperatures in the apartments are above 20 ° C throughout the year in most apartments. The results of the measurements also correspond to the results of the survey, where the majority of tenants stated that they were satisfied with their indoor temperature. The measured values for energy use are higher than the projected values; above all, the energy for heating is higher than the calculated value. This may be due to several factors and to be sure what this is due to requires further studies.
Detailing follow-up measurements of energy use and thermal comfort in a low-energy house Hamnhuset in Gothenburg. The aim is a better understanding of large low-energy houses and to contribute with advice for future projects. The target groups are the construction and installation contractors, as well as building owners and managers. As a complement, a survey was sent out to get the experience feedback from tenants about how they use the technical installations, and how well the installations perform.
The apartments are equipped with demand-controlled ventilation. Very low heating demand is supplied through preheated ventilation air. Energy sources are district heating and solar panels, and there is no cooling. There are mechanical ventilation units with heat recovery with post-heating batteries in two stages: a first central heating coil with district heating, then small electric heating coils connected to each apartment.
