Abstract [sv]

Genom att energin är begränsad i världen och att byggsektorn kräver en mycket stor andel så är arbetet att effektivisera i denna sektor ett av de viktigaste målen i denna bransch. Syftet med detta arbete är att finna en bra, effektiv, och billig metod för att snabbt nå målet med energieffektivitet för Kinas bostäder. Beaktat att Kina är ett stort land indelas det i flera delar med olika klimat för att med större säkerhet nå rätt. Ett typhus har antagits i beräkningarna för fem olika klimatzoner. Programmet Designbuilder har använts och data för isolering och ventilation i ett basfall, ett fall med bättre skal d v s U-värden och ett med värmeåtervinning diskuterats vilka tar längre tid att genomföra och kräver större investering men ändå är lönsamma. Dessa kan förordas med statligt stöd.

Abstract [en]

Due to the energy shortage situation of the world and building sector occupies the most significant particle of total energy consumption, promoting the energy efficiency in the buildings has become one of the most urgent goals for energy develop the profession. The purpose of this project is to look for the most reasonable method, which is efficient and can be carried out in a short term with a lower investment, to reach the goal of energy efficiency in residential buildings in China. Considering that China is a vast territory country, the whole mainland is separated into five parts according to the various climate types in order to research accurately. A base building has been modeled in five climate zones at the same time. The software Designbuilder is used to simulate the base scenario, the building envelope improved scenario and the HVAC system improved scenario. The final suggestion is given according to the comparison of these three scenarios.Besides, some other technologies have been given in the thesis. These methods would take a longer time period or more investment, but still are good choices for residential buildings energy efficiency. They should be promoted in the future by the government support.
