BJF Group’s Mechanical and Electrical Division completed a £3.3 Million M&E fit out at the new Harrow Lodge Leisure Centre operated by Everyone Active.

BJF Group’s Mechanical & Electrical design means that the facility is highly sustainable, achieved through a selection of low energy products and the use of combined heat and power (CHP) generation, photovoltaic (PV) panels and heat recovery systems.  These technologies working in conjunction with a thermally efficient building fabric has resulted in an A+ energy rating.

The standout areas within the new facility are the Pool Hall and fitness suites, both having unique and specific sets of requirements. The pool hall encompasses both an 8 Lane Pool and diving pool boasting Varipool technology allowing for the depth to be altered to suit user needs and ‘Pool View’ drowning prevention which provides additional safeguards to users. BJF installed the mechanical and electrical infrastructure to facilitate these specialist systems.

A well-conditioned controlled environment in keeping with Sport England guidance was achieved though CFD analysis. The correct sizing and selection of air handling units, chlorine resistant ductwork and positioning of fabric air socks provided the optimal air distribution, temperature and humidity control. A fully integrated Trend BMS system provided for setpoint control within.

Owing to the high heat load within the fitness suite the selection of the most suitable air conditioning system was paramount. We chose a high-efficiency Mitsubishi VRF system with around 35 cassettes capable of providing consistency of temperature within a large area and dealing with the pressures of such an environment.

The old centre is now being demolished to make way for expanded car parking including 50 Pod Point electric vehicle charging points, lighting and CCTV which will be installed, tested, and commissioned by BJF Group.
