TClarke Alternative Energy Solutions launches with major win

TClarke is launching Alternative Energy Solutions to help building owners improve EPC ratings for old buildings, meet climate targets, Improve their carbon footprint and critically, make newly available technologies a practical option.

The launch is also marked by the announcement of a major Alternative Energy contract win and one of the very first commercial building energy upgrades on this scale – helping 30 Fenchurch Street substantially improve its EPC rating, within an holistic programme of design works and technology installation.

 Achieving major design stage improvements

 The project was taken from a stage 2 through to a stage 4a design and during this process the original plant concept was reviewed and re-designed with performance improvements and enhancements.

 This was achieved with the implementation of new simultaneous four pipe heating and cooling Air Source Heat Pumps (ASHPs), along with additional air cooled chillers to be provided to the roof area. This enabled the original existing water cooled chillers in the basement and the cooling towers on the roof to be decommissioned and removed.

 These new capital plant improvements enabled the property EPC rating to improve – all with zero impact to the tenant’s business operations.

 Actively engaging manufacturers to ensure optimal equipment selection

 Manufacturers were engaged to ensure equipment selection was robust and satisfied the design criteria, this was confirmed through our TClarke design team. A key factor was the COP and EER of the new plant. Refrigerant and compressor selection were also important to ensuring that optimum performance was obtained.

 Throughout the plant replacement phase, we engaged with the client to demonstrate added value. This was shown with HV & LV electrical works, where existing aged equipment was removed and multiple LV distribution boards were amalgamated into single new larger distribution boards.

 Optimised logistics plan for City location

 30 Fenchurch Street is in the heart of the City; as such the plant logistics are critical to project delivery. These were analysed and modelled to reduce the total number of lifting events and provide a structured plan to meet the programme and maintain the client requirements.
