本研究分析了净零能耗建筑材料阶段的环境影响。可持续景观中心（CSL）是一个三层楼高，24，350平方英尺的教育，研究和行政办公室，位于美国宾夕法尼亚州匹兹堡。这座净零能源建筑的设计旨在满足居住建筑挑战标准。建筑材料生产对环境影响最大的是混凝土、结构钢、光伏（PV）面板、逆变器和砾石。将CSL的LCA结果与标准商业建筑进行比较，发现其全球变暖潜力高出10%，每平方英尺的隐含能量几乎相等，这主要是由于CSL的光伏系统。作为一个净零能源建筑，与使用阶段相关的环境影响预计相对于标准结构非常低。未来的研究将包括CSL的建设和使用阶段，以获得更全面的生命周期观点。
This study analyzed the environmental impacts of the materials phase of a net-zero energy building. The Center for Sustainable Landscapes (CSL) is a three-story, 24,350 square foot educational, research, and administrative office in Pittsburgh, PA, USA. This net-zero energy building is designed to meet Living Building Challenge criteria. The largest environmental impacts from the production of building materials is from concrete, structural steel, photovoltaic (PV) panels, inverters, and gravel. Comparing the LCA results of the CSL to standard commercial structures reveals a 10% larger global warming potential and a nearly equal embodied energy per square feet, largely due to the CSL’s PV system. As a net-zero energy building, the environmental impacts associated with the use phase are expected to be very low relative to standard structures. Future studies will incorporate the construction and use phases of the CSL for a more comprehensive life cycle perspective.
