With global warming and carbon dioxide (CO2) emissions high on the Government’s agenda, it has never been more imperative to build efficient low carbon developments. Since the first release of the Government’s energy white paper in 1999/2000, Walker Mower, within the group has stayed at the forefront of the low carbon industry, maintaining solid work ethics and design.

With our years of experience and knowledge of the mechanical and electrical building industry, we can provide clients with in depth, cost effective solutions to meet any site specific project requirements.

Forefront of Sustainable Design

Walker Mower, within the group was involved in the AIM C4 development with Barratt Homes. The aim of this development was to achieve Code for Sustainable Homes Level 4 through innovative materials and products only, without the use of renewable technologies. To help reduce the predicted CO2 emissions a Waste Water Heat Recovery System (WWHRS) was implemented into the design. This uses the waste hot water from a running shower to transfer heat into the incoming water so that the boiler demand is reduced. The development was used as a study to see how much energy can actually be saved through the WWHRS. Walker Mower, within the group produced the Energy Performance Certificates for four house types on the development and were also involved in the mechanical and electrical designs.

Walker Mower, within the group was also the mechanical and electrical consultant for Barratt Home’s Hanham Hall development. This was an important new development in the UK with the original Hanham Hall, a grade II listed building, transformed as the centrepiece of the development. Around 185 new homes were built with community facilities, green spaces and cycle routes located on-site.

Walker Mower, within the group are always keen to investigate new technologies for clients, such as river cooling. This technology was used on the Baltimore Wharf development (client CJ O’Shea) to provide cooling to the residential tower and hotel. Cold water is drawn into a heat pump from the River Thames and passed through a heat exchanger where the heat from the warm return water in the cooling system can be transferred. This cools the system water before returning back to the chillers reducing the overall load of the system, therefore reducing on-site CO2 emissions. This can also allow the size of the chillers to be reduced as the overall load is reduced.

As part of our service, we can provide reports to satisfy latest planning authority requirements. Our feasibility division also comprises of many other disciplines, to aid clients in the efficient completion of their projects.

Another technology that Whitecode specified was a glycerine Combined Heat and Power (CHP) engine. This was used on 85 Highbury Park in Islington (client Mount Anvil). Glycerine is a by-product of biodiesel production, one gallon of glycerine is produced for every nine gallons of biodiesel. Burning glycerine produces much lower emissions than burning diesel fuel because of its density and high oxygen content, therefore performing really well in the Code for Sustainable Homes assessments.
