For speculative, Shell and Core projects there will be a significant level of uncertainty regarding equipment loads and usage patterns. Project teams should make the best estimates they can based on available data for similar projects, instead of using the National Calculation Methodology occupancy assumptions. Where sites have multiple speculative, Shell and Core buildings it is acceptable for the ‘Prediction’ work to be the same across all the units. The design team would need to be sure that all the units would have the same type of tenant and be used in the same way. This is in keeping with the aim of the ‘Prediction’ credits; to predict energy consumption as accurately as possible. If the users are known to be different, this approach would not be acceptable.
