Abstract: A building can be considered as a hierarchy, composed of the building, the system, the subsystem, the member and the material level. This paper studies life cycle CO2, (LCCO2) corresponding to each of these levels and discusses corresponding means of reducing CO2, emissions. To illustrate, calculations were made with respect to an apartment building. If the subsystem level having a building life of 1,000 years should be feasible, if would be
possible to reduce LCCO2, by about 50%, compared to the case of rebuilding every 100 years.
In the case of rebuilding every 100 years, if reuse at the member level should be feasible, about 30% reduction of LCCO2, would be possible. Any recycling at the material level would permit a cut of about 20% in LCCO2.
