An Energy Performance Certificate (EPC) was produced for Centre Gate, Bristol, assessing the energy performance of the existing commercial building and its associated building services.

The assessment considered the building fabric and construction, including the existing windows with secondary glazing, together with the performance of the installed electric heating, ventilation, cooling and lighting systems. Particular consideration was given to the characteristics and constraints of the existing building fabric and services in establishing its overall energy performance.

The completed assessment achieved an EPC rating of D (91), reflecting the existing building’s energy performance and the characteristics of its fabric and building services. The assessment provides a benchmark of the property’s current energy performance and can be used to inform future energy efficiency improvements and refurbishment strategies.

An Energy Performance Certificate (EPC) was produced as part of the refurbishment and change of use of the former Bridewell Police Station in Bristol into a YMCA youth hostel, completed in 2018.

The assessment evaluated the upgraded building fabric and retained structure, alongside the performance of new and existing building services, including heating, ventilation, and lighting systems. Particular consideration was given to the constraints associated with refurbishing an existing building, ensuring that energy performance improvements were achieved while respecting the original structure.

The EPC analysis established the building’s regulated energy performance and confirmed compliance with the applicable Building Regulations for refurbishment projects.

The completed development achieved an EPC rating of B (37), reflecting a significant improvement in energy performance and supporting the delivery of efficient, fit-for-purpose accommodation within a repurposed city-centre building.

Energy assessment services were carried out for the refurbishment of Merchants House, a multi-occupancy building.

The EPC assessment encompassed the building’s non-domestic areas, including office spaces, circulation zones, and communal facilities. The project involved significant upgrades and reconfiguration of the existing structure, necessitating a comprehensive evaluation of both retained and improved building fabric and services.

The analysis considered regulated energy uses such as space heating, hot water, ventilation, and lighting. The assessment modelled the thermal performance of the refurbished building envelope and the efficiency of both new and existing building services to ensure compliance with Part L of the Building Regulations.

Special attention was given to challenges inherent in refurbishing existing structures, including thermal bridging, air permeability, and the integration of enhanced insulation measures within the constraints of the original construction. System selection, control strategies, and operational performance were carefully evaluated to optimise energy efficiency across all building zones.

The resulting EPC assessment confirmed that the refurbished building meets required regulatory standards, supporting improved energy performance, reduced operational costs, enhanced occupant comfort, and a more sustainable commercial environment.
