THE ESTIMATION OF ENERGY-CONSUMPTION AND AMOUNT OF POLLUTANTS DUE TO THE CONSTRUCTION OF BUILDINGS

In this paper, the total energy consumption and environmental pollution caused by construction are quantified using the Inter-Industry Relations Table in Japan. The size of the six buildings which are evaluated in this study vary from 1502 m2 to 216 000 m2. The major results are as follows: total energy consumption caused by construction of office buildings is 8-12 GJ/m2 of floor area; CO2 production is 750-1140 kg, SO and SO2 720-1430 g, NO and NO2 700-1140 g, dust 70-130 g per m2 of floor area; the construction cost per square meter of floor space is proportional to the energy consumption and production of pollutants; structural work is shown to be high in energy consumption and CO2 exhausted per unit cost of construction; industrial waste exhausted in finishing work is higher than two other categories of the work (structure and equipment); equipment work is shown to be relatively low in energy consumption, CO2, NO, NO2 and industrial waste produced.
