| Research Abstract |
It is important to control the life cycle environmental loads of a house 'from the design stage. To this end, the design method for low-loads house may help to reduce the environmental impacts from human activities.
Firstly, the system of house generating was established. To this goal, data of construction methods and building materials were collected. An easily modified database program called "GA simulation database of building" was then created.
Secondly, the standard model of detached house was taken up into the research. Life cycle CO_2 emission (LCCO_2), life cycle cost (LCC) and final wastes. were regarded as the variables of environmental loads. Genetic algorithm (GA) was applied to search the optimal combinations of construction methods and materials by reducing the 3 variables. The attributes of house dimension were also influence the 3 variables. Detached house models with changing shape were then established. The house with optimal shapes and combinations of construction and materials were then obtained by GA.
Finally, from the perspective of urban planning, the research focused on the house dimension and its location in the city. The CO_2 emission from each household (Total CO_2) was defined as the summation of the LCCO_2 of his/her house and the CO2 emission from his/her commuting trips. By given certain constrain on Total CO_2, an equilibrium model of house dimension and commuting distance was established. The commuting mode was supposed only by railway. Results indicated that if the. house were closer to the urban center, which means the commuting distance (D) decreased, the gross floor area of the house (S) could be potentially larger. The indifference curve of S and D was then obtained by applying the equilibrium model.
