Goodman House - Decarbonisation

Decarbonisation Strategy and Detailed MEP Design

With a highly challenging programme, WP3 were able to successfully deliver a detailed MEP design for the complete decarbonisation of this multi-tenanted and live office building, replacing the traditional gas boiler heat source with modern electricity driven Air Source Heat Pump and Water Source Heat Pump technology.

Working closely with Mitie and Essex County Council, we first reviewed previous feasibility works to determine where improvements could be made and identify risks to the effectiveness of the solution and the ongoing performance of the building. We developed multiple options very clearly outlining the benefits and disadvantages of the various approaches to allow all parties to understand the impacts on cost, programme and building performance to determine the optimum solution to proceed with.

Drawing on all our resources, we engaged early with the supply chain to select equipment for early procurement to secure both delivery slots for plant and funding from available schemes. As part of our due diligence we assessed other associated plant on the site to ensure compliance and effectiveness with the new plant being installed to ensure all would operate efficiently on completion.

We completed detailed utility assessments and liaised with the existing suppliers to determine current site capacity, current peak and average consumption and available network capacity. This helped further inform project costs and procurement strategy. This was particularly critical in the success of the project, with network and site electricity supplies being the single most limiting factor to the continued rollout of heat pump technologies across the UK

Priding ourselves on not simply doing a ‘design and dump’, we set out a plan for phased works and logistics around completing the works on a challenging and operational site.
