To fulfill it, we need to pay for it, namely a higher cost. Thus, it is considered that cost and benefit must be taken into account when we are going to make an investment in new measures which improve the state of constructions. In this way, life-cycle costs analysis (LCCA) can provide the investors or operators with the best suggestions over the cost benefit. It is all well known that the consumption of energy is the second most expensive cost after a building is finished, and comes into operation, due to the energy consumption during their life cycle is responsible for the second most expenditure, the extra cost should be able to be covered by future energy savings. Also, what if the building owner has a limited budget or a requirement for the capability of the energy saving system? To answer these questions, this research proposes to use BIM to make a construction model first and estimate the approximate cost of the building. Secondly, we use software to analyze the yearly energy cost through the model. Thus, with these two things, we can obtain information about what are the best components and materials for different building.
