This button triggers the Part L2 (2021) compliance analysis, which has five stages:
· U-value checks
· Simulation of the actual building using ApacheSim
· Initial Apache Simulation of the notional building to adjust PV areas
· Second Apache Simulation of the notional building using adjusted PV areas
· Invocation of the BRUKL compliance calculator
The U-value checks test for compliance with the fabric requirements of Regulation 25. A test failure halts the compliance analysis.
The simulations are performed over a year using the appropriate CIBSE Test Reference Year (TRY) weather dataset. Simulation settings for these simulations may be edited in a facility accessed via the Building & System Data dialog. Simulation settings are shared between the three types of simulation (except where overridden by the demands of a particular type of simulation – for example the requirement for compliance simulations to cover the whole year).
The BRUKL compliance calculator uses the simulation results to calculate the TER and BER, BPER & TPER which then determine whether compliance has been achieved. The results are incorporated in reports accessible via the Results tab.
