In a heartwarming endeavor for a great cause, the Global Group MEP and Sustainability Engineering division (GBE) recently completed a remarkable project at Treetops Hospice. This endeavor was undertaken pro bono for Children in Need, highlighting GBE's commitment to giving back to the community.
One of the key aspects of this project was the meticulous calculation of energy and thermal data, which proved instrumental in ensuring the hospice's compliance with Building Regulations Approved Document Part L. This regulatory requirement mandates that a commercial new-build structure must possess a valid Energy Performance Certificate (EPC).
Generating an EPC involves employing advanced energy modeling techniques, and for Treetops Hospice, iSBEM (Simplified Building Energy Model) software was the tool of choice. This software ingeniously incorporates the building's architectural features and energy-consuming systems into its calculations, enabling the determination of critical metrics such as the primary energy rate (kWh/yr) and CO2 emission rate (kg/CO2/yr).
The crux of this energy modeling exercise lies in ensuring that the building emission rate (BER) falls below the target emission rate (TER) set for a notional building derived from the calculation. Meeting this criterion guarantees Part L compliance and the issuance of a valid EPC.
The data collected during this modeling effort, including the energy rate (kWh) and CO2 emission rate (kg/CO2/yr), provides tangible figures that can be fine-tuned through building improvements. GBE meticulously analyzed the results and provided insightful recommendations for further enhancements, such as:
