Full textThis master thesis has been carried out in the autumn of 2011, on assignment of the department of Applied Physics and Electronics (TFE) at Umeå University. The thesis is a part of the ongoing project, Energieffektivt byggande i kallt klimat, which is a collaboration between the municipality of Umeå, Umeå university and market participants in the Umeå region. The goal of this work is to create and compile a solid base of measurements to show the energy saving potential in the housing sector and to explore if there is an increased risk of mold, rot or fungus growth in energy efficient houses. The long-term goal is that the result of this project will lead to increased motivation to build energy efficient houses even in these latitudes. A compilation of the energy requirement has been made for four single-familyhouses in the Umeå region throughout the year 2011. Temperatures and humidity has continuously been logged in the various layers of the building components and in indoor and outdoor air. Flow rates and temperatures of water in heating systems and to hot tap water have been logged. Electricity consumption has also been continuously collected. In total, between 27 and 40 sensors were installed in each house. The energy use has thereby been identified and categorized according to if the use is for heat, hot tap water, household electricity and in terms of total electricity- and energy use. Performance has been investigated for installations with energy saving purposes such as heat exchangers, a 30 m long preheating pipe buried in the ground and a geothermal heat pump. The results of the compilations show that the houses, with normal year corrected values, have an energy requirement for heating and hot tap water at between 67 and 81 kWh/m2y. The heat and hot tap water requirement for one of the houses was only half of the requirement in BBR of 130 kWh/m2y for houses with other type of heating source than electrical heating. The measurements show that there is no risk of mold or rot anywhere in any of the houses. In one of the houses it was showed that a preheating pipe along with a wellfunctioning heat exchanger was enough so no additional pre-heating of the incoming air was necessary, even during the coldest period of the year. The geothermal heat pump delivered in average 2.5 times more energy than it consumed. This reduced the amount of purchased energy for heating and hot tap water by about 60 % on a yearly basis. Overall, there is nothing in this research that indicates that there are any hinders for constructing energy efficient buildings in cold climates. No increased risk of rot or mold has been detected which has been a common misconception about energyefficient, airtight houses. Rather, there is a quite large saving potential both moneywise for the individual and for the environment, in both the short and the long term.

Full textMålet med detta examensarbete är att ta fram en lösning som gör det möjligt att utforma fönster och bostadshus i olika stil och fortfarande kunna bygga enligt energihusprinciper. En röd stuga med vita knutar och fönster som ser likadana ut i alla väderstreck är ett exempel.
I lågenergihus är väggar, golv och tak mycket väl isolerade, de har ett mycket lågt U-värde. Fönster och dörrar, som har ett jämförelsevis högt U-värde, bryter detta klimatskal, vilket gör dem till kritiska punkter för energiläckage. Fönster ger upphov till önskade och oönskade energiflöden, till exempel dagsljus, värmeförluster, strålningsvärme och luftutbyte. I energihus är det särskilt viktigt att kunna kontrollera dessa flöden för att uppnå komfort och minimera energiförlusterna.
Arbetet resulterade i IsoSol, en utvändig jalusi som rullas upp ovan fönstret och döljs i väggkonstruktionen när den inte används. Ett flexibelt solskydd som i helt nerfällt läge mörklägger effektivt och isolerar tack vare materialval och inneslutna sidostycken. IsoSol är uppbyggd av en kombimatta sammansatt av tät väv och nålfilt. För att huset inte ska se igenbommat ut utifrån sitter horisontella ribbor i skummad polyuretan med trästruktur på den yttersta väven. Konstruktionen blir tät eftersom jalusins sidokanter sitter 10 cm in under fasaden. I över- och underkant finns gummilister som ökar tätheten. En automatisk styrning av upp och ner gång samt möjlighet till tidsprogrammering finns med hjälp av en motor från Somfy Home Motion.
IsoSol ger fönsterkonstruktionen ett U-värde på 0,31 W/m2K jämfört med 0,98 W/m2K för enbart fönstret och ett g-värde, mått på solenergitransmittansen i procent, på näst intill noll, 54 % utan IsoSol. Lösningen passar alla sorters fönster, skyddar rutan från väder och vind och ger ett ökat skydd mot inbrott.
The objective of this project is to develop a solution that makes it possible to design windows and buildings in different styles and still be able to build according to the principles of energy-houses. A red cottage with white corners and windows that look the same in all directions is an example.
In low-energy-houses are walls, floors and roof very well insulated; they have a very low U-value. Windows and doors, that have a relatively high U-value, break this climate shell, which makes them critical points for energy leaks. Windows give rise to desired and undesired energy flows, such as daylight, heat loss, radiant heat and air exchange. In energy-houses it is particularly important to be able to control these flows to achieve comfort and minimize energy losses.
The project resulted in IsoSol, an exterior roller shutter that is rolled up above the window and hidden in the wall structure when not in use. A flexible solar control that in its closed position are an effective darker and insulator as a result of material choice and enclosed sides. IsoSol is made up of a combination carpet composed of impenetrable fabric and needle felt. In order to not make the house look closed from the outside there are horizontal bars of foamed polyurethane with wooden structure on the outer fabric. The construction is reducing the leaks because the side edges are integrated 10 centimetres underneath the facade. An automatic control of when to open and when to close and time-programming is possible by the use of a motor from Somfy Home Motion.
IsoSol gives the construction of the window a U-value of 0,31 W/m2K, compared to 0,98 W/m2K entirely the window, and a g-value, measurement of the solar transmittance, close to zero, 54 % without IsoSol. The solution suits all kinds of windows, protects the window and provides increased protection against break-ins.

Full textA large proportion of the energy consumption is in the building industry and a large part goes to heating our homes and premises. In the developing countries' development now threatens the large consumption of energy in our earth's climate. It is in the West world that we must be good role models in terms of energy efficiency. One solution to reduce energy consumption for heating of buildings may be to continue to build low energy houses and passive houses, but it is also about rebuilding the buildings that currently have high energy consumption such as the old Million program Houses. These buildings will be standing many years and their energy consumption will not diminish over time by itself and energy prices will certainly not diminish in the future. This report will touch on the subject mainly new construction, how to build an energy efficient building, but a smaller portion will touch on the subject rebuilding, particularly the solutions that can fit into economic terms.
Calculations have been done to link the concepts of Umean of a building and its energy consumption. This was done by calculations using an Excel document created in connection with this thesis.
The buildings and architectural solutions addressed in this report will focus on apartment buildings where the partner of this thesis is Eskilstuna Municipal Building. Eskilstuna Municipality Property manages buildings and premises to Eskilstuna Municipality, but also owns their own house with rental apartments.
