Abstract [sv]

I arbetet  utreds värmeförlusterna relaterat till  huset. Temperatur och värmeförluster mättes och identifierades med en värmekamera. Värmeförlusterna för byggnaden beräknades och en känslighetsanalys gjordes. Resultaten visar att värmeförlust genom fönster och genom luftläckageförluster står för 67 % av de totala värmeförlusterna. Väggisolering på 15 cm ger störst påverkan vid låga utomhustemperaturer, då effektenförlusten minskar som mest för väggen. Den extra ytterisoleringen ger en energibesparing på mellan 5000-5800 [kWh/år]. Treglasfönster ger en  besparing på 3000 [kWh/ år] jämfört med tvåglasfönster. 

Abstract [en]

In the work,  the household energy consumption is investigated with respect to various heat loses from one single house.  The local temperature distribution was measured by means of heat camera to identify local heat flow. The heat dissipation from house was calculated. A sensitivity analysis was made. The results show that the heat loss through window and air ventilation are responsible for 67% of the total heat loss from the house. 

The wall insulation is important at low environmental temperature outside the house, the extra insulation results in a sharp decrease of the effect loss during periods with cold outside temperatures. 15 cm extra insulation give rise to an energy saving of between 5000-5800 kWh/year.

Three-glass window can save a decent amount of energy up to 3000 kWh/year compared to two-glass window.
