Our Own Internal Reference Installation
This project documents an internal reference installation delivered at Mansfield Pollard’s Bradford headquarters as part of the company’s ongoing programme to decarbonise its own operational estate.
The installation forms a permanent upgrade to the building’s core services and has been implemented under the same technical, spatial, and operational constraints typically encountered across live retrofit projects.
Two modular HP Series air handling units now provide full mechanical ventilation, heating, and cooling to a 10,000 ft² open plan office. The systems were installed while the building remained fully occupied and were selected using the same engineering criteria applied to client estates, including electrification objectives, system performance, installation practicality, and long term operational control.
The project was undertaken to remove fossil fuel dependency from this part of the estate and to establish a robust internal reference for applied HVAC decarbonisation. System performance has been evaluated using declared engineering assumptions and real operational data, enabling energy use, carbon impact, and financial return to be quantified in a transparent and repeatable manner.
This project profile sets out the technical rationale, installation approach, control strategy, and performance outcomes, providing a representative reference for similar decarbonisation initiatives across commercial, education, healthcare, and public sector buildings.
Project Context and Objectives
This internal reference installation was developed to address a specific and representative challenge. How to decarbonise a primary HVAC system within a live, permanently occupied building while maintaining environmental performance, installation certainty, and operational control.
The existing building services infrastructure reflected conditions common across many retrofit environments. Plant space was constrained, the building remained in daily use, and any solution had to be delivered without disruption to occupants or reliance on extended shutdown periods. The project also needed to align with Mansfield Pollard’s wider electrification strategy and provide a defensible basis for assessing energy, carbon, and cost outcomes.
HVAC was identified as a priority system due to its contribution to overall building energy use and operational carbon. The objective was to remove fossil fuel dependency from this part of the estate and replace it with an all electric solution capable of delivering ventilation, heating, and cooling from a single integrated system.
This project was also intended to establish a practical internal reference for applied decarbonisation. One that could be evaluated using declared engineering assumptions, measured operational data, and a methodology consistent with that applied across client estates.
