When installing high-performance mechanical systems, it is recommended to apply life-cycle analysis to the trade-offs between initial capital and operating costs. The life-cycle analysis is the investigation and evaluation of the environmental impact of a given product or service caused or necessitated by is existence. High performance mechanical systems generally require more initial capital investment, but have the possibility of paying for themselves in reduced operating expenses over the building's lifecycle. It is important to consider lifecycle costs when deciding on high performance systems, both to ensure that you are not giving up substantial long-term savings due to higher initial costs, but also to ensure that the higher initial costs will indeed be made back through normal operating usage.
