ABSTRACT
This study aims to investigate the environmental and economic performances of
sustainable building technologies applicable to a multi-family residential and office
ensemble situated in Iasi, Romania. The technologies mentioned in this study include: exterior insulation, double envelope system, TRI-generation of the energy, BMS (building management system), LED technology. All three buildings of the Renaissance ensemble benefit from south-oriented green requirements of contemporary architecture: double-skin facades, curtain walls, terracotta panels, etc. A second skin façade may also cause an increase in materials and design costs, but would save energy consumption. We have implement the TRI-generation of the energy (electrical, heating, cooling), which is a quite efficient and modern solution. Building Management System will provide comfort at a minimum energy cost. In order to allow the effective space utilization, a zonal energy distribution was designed. LED technology has been very useful especially for dynamic lighting of low energy consuming places/surfaces (facades, parking areas, etc). The conclusions of the study applied to a certain investment – Renaissance ensemble- indicates that the sustainable building technologies, although the initial investment costs are higher than conventional technologies, are more economical and efficient in terms of life-cycle cost due to the reduction of energy and environmental costs.

Keywords: double envelope system, dynamic lighting, sustainable technology, life cycle cost analysis.
