Theme B: Creating a livable, healthy and environmentally viable citiesThe quantities of building materials used in the building components at initialstage and repair and maintenance stage. The data source could be the bills ofquantity or the cost plan.The repair and maintenance frequency of a building component. The data sourcecould be based on the repair and maintenance data in similar project.Real bill data or best-estimated data for operational water, electricity and gasconsumption. The data source could be the real electricity, gas and water bill ofsimilar project or best-estimated consumption figure based on the engineeringassumption on the light power density, the equipment power density, the details ofAC plants, the lift and other building services equipments.TASC can measure the ten environmental impacts and economic impacts of abuilding based on the data inputs and highlights the environmental and economic‘hotspot’ elements and functional units of a building from the whole life-cyclepoint of view.4. RESULTS OF THE LCA STUDYThere are three possible way to indicate the environmental performance ofbuilding archetypes(1) The total HK E-points of the building;(2) HK E-point per construction floor area (CFA); and (3) HK E-point perinhabitant of a buildingFig. 1 shows total whole life HK E-points of the assessed building archetypes. Fig.2 shows the whole life HK E-points/ CFA. Fig. 3 shows the whole life HK E-points per inhabitants of the assessed building archetypes.161
