BREEAM Ene 01, Reduction of energy use and carbon emissions, is the credit that drives the modelling scope. We build the proposed building model against the BREEAM notional baseline, run dynamic thermal simulation in DesignBuilder, and document the Energy Performance Ratio for New Constructions (EPRNC) to BREEAM standard. We deliver compliance for BREEAM International New Construction, BREEAM In-Use, and BREEAM ES Nueva Construcción.
