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.

Disclaimer and limitation of liabilities

This calculation tool represents the professional opinions of the members of the evaluation team. The evaluation team members, the Solar Energy Research Institute of Singapore (SERIS) and the National University of Singapore (NUS), exclude any legal liability for any calculation made with this tool. In no event shall the evaluation team members, SERIS, and NUS of any tier be liable in contract, tort, strict liability, warranty or otherwise, for any special, incidental or consequential damages, such as, but not limited to, delay, disruption, loss of product, loss of anticipated profits or revenue, loss of use of the equipment or system, non-operation or increased expense of operation of other equipment or systems, cost of capital, or cost of purchase or replacement equipment systems or power.

Available Area

This should be your "net" area available for BIPV implementation split roughly according to the cardinal directions. The energy generated is computed based on the irradiance received on each respective façade.
