Crewe Fire Station; Net Carbon Zero

  • The Project

     

    This ongoing project is to replace the existing Crewe fire station. Robert Whetham
    Associates (RWA) are creating the detailed building services design of the new fire station
    on behalf of the M&E (Mechanical and Electrical) Contractor, T Clarke. The project also
    includes building a temporary fire station for use while the works are carried out.
    The main contractor is ISG Construction, the architects are Bradshaw Glass and Hope, and
    the client is Cheshire Fire and Rescue Service.

    RWA are currently at RIBA (Royal Institute of British Architects) stage 3 of the design which
    is the contractor proposals stage, focused on Spatial Coordination. Stage 4, the finalised
    design, will commence shortly and the project will begin in a few months’ time to be
    completed in 2023.

    Our Solution

     

    RWA has designed a solution that takes into account sustainability as well as mechanical
    and electrical design solutions.

    We collaborated with other members of the design team to create a 3D model of the building
    in BIM (Building Information Modelling). We used Revit software to bring all elements of
    architecture, engineering and construction into the model to enable the team to deliver a
    more efficient and cost-effective project.

    Our objectives are based on meeting the BREEAM (Building Research Establishment’s
    Environmental Assessment Method) standards of excellence. We have also incorporated
    designs that will enable the new build to achieve nett zero carbon targets. These will be
    achieved through air source heat pumps for heating and hot water, photovoltaics for
    electricity, and energy-efficient lighting and controls.

    RWA introduced passive design measures to provide a reduction in the building emission
    rate, a reduction in space heating requirements and annual solar gains (heat increases from
    absorbed solar radiation). This ensures fabric heat losses are minimised, good levels of
    natural daylight are achieved, and solar gains are utilised during autumn and winter. These
    measures include:

     

    – Installation of solar shading devices such as bris soleil

    – Improvements to window, wall, ground, roof and glazing U values (thermal transmittance)

    – Provision of full height glazing in areas to maximise daylight levels at the deepest part of each room.

     

    In conjunction with Seven Consulting, RWA carried out calculations and produced reports to determine the best method of reducing building emission rates, making use of low and zero-carbon technologies and passive design measures. This was carried out to ultimately
    provide a building that is nett zero carbon.

     

    The reports that we produced were-

     

    – Thermal comfort calculations

    – Daylight analysis calculations

    – Reduction in energy usage

    – Low zero carbon technologies

    – Passive design analysis

    – BRUKL (Building Regulations UK, Part L) calculations

     

    Solution Benefits

     
    The new fire station will accommodate enhanced modern training facilities and additional
    office space. The upper floor will be accessible by a lift which the current fire station doesn’t
    have. The building will be constructed with electric vehicle charging facilities.

    As a nett zero carbon building, the new fire station will be highly energy-efficient and powered
    by onsite renewable energy sources with any excess carbon being offset.
