Housing with low environmental impact Project 2008 - 2010 Regional Council of Jämtland – The Regional Energy Agency in co-operation with Mid Sweden University Östersund Municipality County Administrative Board
Why is it interesting for us working with low energy housing?
- Cold climate, high energy costs - EU:s targets 20-20-20 - We have the knowledge and good building tradition of wooden houses. - Better houses for individuals; good indoor climate and low maintenance costs. - Reduce the use of electricity for heating houses. (It´s better if the electricity is used for other things; loading electrc cars for example!)
Building Regulations; Energy requierements in new houses, kWh/m2 County of Jämtland = climate zone I

The legislation is ”week”. It is possible to build far better houses! Passive houses: 50-60 kWh/m2
Energy consumtion in houses
BOVERKET - The Swedish National Board of Housing, Building and Planning – Building Regulations Municipality – building permit (documents including calculation of estimated energy consumtion). Municipality; Free of charge consultance by Energy advisor – In Sweden every municipality has an energy advisor. Financial support from Swedish Energy Agency. We recommend people to get in contact with the advisor when planning a new house – it´s best to do right things from the beginning. More expensive to do it afterwards! When planning a house a lot of decision has to be taken and for many people “Energy” don´t have the highest priority.
The project - Purpose •
To give advice about how to build houses with high energy efficiency and light ecological footprints through a smarter use of materials, energy, methods and thinking.
• To make awareness about climate change scenarios – and possibilities to act – within the building sector. • To establish networks among SMEs about new building methods
Method • Seminars with speakers from R&D • Courses with thematic discussions • Free of charge consultance • Study visits • Establishing networks • Printed information
Target group • Individuals who want to build new house •SMEs within building sector • Municipality´s permission unit • Media
Exhibitors at a Trade Fair
Study visits •
•
One trip to the “Center of passive houses in Sweden” (www.passivhuscentrum.se). The project paid for the registration fee and the participants for the travel cost. The first passive house in Östersund. People from the municipality, County Administrative Board, architects, energy consults participated.
Typical house catalouge…
Example – University course •
Co-operation: During the summer the university has a course in sustainable construction. The first two days the lectures are open for anyone to participate. It´s good for the relation between students and companies.
Courses with thematic discussions •
• •
During three occasions, 14 persons participated in the course. Co-operation: Adult education association Areas we discuss: -Building regulations, -ventilation, heating system, -energy consumption, -operation cost, -architecture, building construction
Establishing networks •
• •
Co-operation: With two other network in the north of Sweden. “Sustainable construction in cold areas” and “wooden towns”. Seminars in our region about building in wood. Network with other Regional Energy Agencies in Sweden (association; Sweden Energy Agencies). In 2013; seminar on sustainable building in 11 counties in Sweden. (“Lecturer on tour”).
Printed information •
•
A small folder about sustainable buildnings/construction and passivhouses. To have at exhibitions for example. A brochure ”How to build energy efficient” for building inspectors (at municipality) and individuals who will build a new house. It´s about materials, (solar) energy, construction of walls, floor, roof, isolation etcetera...
Results • Some low energy houses are built, one by a family who participated in the “course with thematic discussions”. • Municipality is planning for areas with low impact buildings. • Anyone who build a Passive house in Östersund will get the fees for building permission refunded. • A growing interest for low energy housing; municipalities, builders, the public. • Increased knowledge in the region. • Today we have several good examples of low energy building.
Low energy houses School, Krokom Municipality
The opening ceremony was held 27 August 2012, at the start of the autumn semester. The school is a low-energy building. The school is designed in a way that will arouse curiosity and make it easy to socialize. The heating system is a combination of district heating, ventilation and solar energy. The electricity comes primarily from photovoltaic cells. Outdoor environment is designed in view of the outdoor education applied in Krokoms municipal schools with opportunity for outdoor education and exciting room formations on the school grounds.

Wall construction
Air tight • A myth of passive houses is to seal the House can be problematic, and give rise to "sick building" (moisture mold and the like). • However, it is very important to seal houses are well-ventilated, with control of the air flow.
Health aspects Passive houses are well-ventilated houses. Examples are from a family in which a child with pollen allergies could reduce her medication dose when the family moved into a passive house - thanks to the ventilation was so good, with efficient filters.

Economic aspects of Passive Housing • The additional cost to build a passive house is approximately 5%. • The additional cost is made up partly of construction materials, more insulation and sealing materials. But also of more hours for construction process because it requires greater accuracy, among other things to make the House airtight. • Operating costs for the heating of a passive house is about half compared to a conventionally built House.
