This BIPV LCC calculator is a simplified assessment tool that should enable architects and building-related professionals to make a decision about implementation of BIPV into the façades during early design stage. The calculator includes certain benefit calculations of integration of BIPV systems (i.e. electricity bill savings, and environmental implications), which are based on generalised energy efficiency assumptions, using SERIS' most-likely future price scenarios. Future electricity prices in Singapore are influenced by many factors such as: unpredictable oil prices, supply-demand characteristics, and competitor's behaviour, to name a few. Note that for contestable clients, contractual arrangements vary from case-to-case. This calculation uses a simplified average price assumption and does not account for tax implications (e.g. depreciation period is aligned to operational life). The calculator provides an indication of the LCC of a BIPV application and should not be the only basis for making an investment decision.
