CHP solution for student accommodation blocks

Published: 1 November 2019 - Carly Wills

Helec Ltd, a specialist in the specification, design and installation of Combined Heat and Power systems (CHP), has announced the completed supply and commissioning of a CHP solution at Crown Place Norwich (formerly St Stephen Towers), which has been converted by Crown Student Living into student accommodation.

Helec was selected to provide a low nitrogen oxide (NOx), CHP system for the redevelopment, which is expected to save an estimated £38,000 in energy costs and 204,000kg of CO2 emissions per year. Helec specified and supplied two 33kWe Energimizer EM33NG CHP systems, which were installed in the plant room by building services company F P Hurley in June 2019. The refurbishment of the 705-bedroom accommodation block opened in September 2019.

F P Hurley, a mechanical and electrical systems contractor, has been partnering with Crown Student Living over a number of years in order to design and deliver complete mechanical and electrical services. F P Hurley had previously commissioned Helec with other projects, delivering CHP solutions to new plant rooms within new build student accommodation blocks.

In December 2018, Helec was brought in to commission a solution to the hot water requirements and to help reduce electrical power consumption of Crown Student Living’s Crown Place Cardiff, a 374-bedroom student accommodation block. The requirement was to ensure consistent hot water throughout the year while keeping costs to a minimum per residence. Taking into account all individual requirements, an Energimizer EM22NG Combined Heat & Power unit was specified and installed within the building’s plant room. This CHP system is expected to lead to annual fuel savings of £9,900 and reduce annual CO2 emissions by 56,500kg.

Earlier in 2018, another Crown Student Living project, a new 576-bed student accommodation block, Crown Place Portsmouth, specified and installed two 22kWe Energimizer EM22NG CHP units to deliver hot water services and on-site electrical power, reducing the need for grid dependency. It was estimated that this CHP system would lead to annual fuel savings worth £21,000, and reduce annual CO2 emissions by 114,000kg.
