Stride Treglown - Project Background

Overview

Stride Treglown is an award-winning architectural practice. Stride Treglown is an award-winning architectural practice. The new Cardiff office was designed to be carbon neutral, minimising energy consumption. Driven by this mission, they were on the lookout for some reliable renewable solutions.

Stride Treglown, Cardiff Wales

The Challenge

Our client also was keen to showcase the various possibilities offered by the latest renewable technologies, demonstrating how effective they can all be. Stride Treglown’s mission of energy efficiency is aided by a highly insulated timber ‘envelope’ construction. Boasting a natural ventilation system, this encourages the circulation of fresh air.

Our Custom Solution

Treco’s complete installation, commissioning and maintenance service included:

  • A top-of-the-range, fully automated 50kW Guntamatic Biocom biomass boiler, with automatic ignition.
  • The boiler can burn wood pellets, miscanthus pellets or grain and the client’s choice of fuel was wood pellets.
  • Electronic control panel, enabling the client to switch between fuel types.
  • 1,000 litre thermal store.
  • 5 tonne external fuel silo specified to minimise required space.
  • Integration with the heating system.
  • De-ashing into ash box.
  • Lambda probe control for optimum combustion.
  • Design of system compliant with RHI requirements.
  • Assistance with final RHI application including heating schematics.
  • Delivery, installation, commissioning, programming and end user training.

The Result

The renewable technologies installed are successfully offsetting the building's overall CO2 emissions.

The project achieved an Energy Performance Certificate rating of A+ and the building will be carbon neutral of 0kg CO2/M2 per annum.

In October 2009, the project became the UK's first "BREEAM Outstanding Office" development, gaining an 89.12% rating at design stage.

The Incentive

A project of this size would gain upwards of £5,519 every year for 20 years, index linked to inflation and to gain a fuel cost saving versus oil of 50%-80%.

The fuel cost savings and RHI payments combined will deliver a payback on the capital cost of the equipment in about five years.
