Caterham business, Flatt Consulting, are proud to announce that at the prestigious CIBSE Building Performance Awards ceremony they were announced as the winner of the CIBSE Refurbishment Project of the Year (Value Over £5M) 2015.

The refurbishment of Premier House, a 1970s concrete/brick-skinned office building in Twickenham, was one of the first projects to be undertaken by Low Carbon Workplace, a collaboration between The Carbon Trust, Threadneedle and Stanhope. The building was typical of its age and type: existing services included an inefficient, high-energy-usage, high-carbon-emitting, VAV air conditioning system with split system DX cooling units.

The refurbishment set out to introduce low-carbon design techniques and technologies for internal climate environmental control and 'sustainable' solutions, to achieve a building with low emissions and low water use.

Once the refurbishment was completed, at the end of the first full year of occupation, energy consumption had been reduced by 64%.  This equated to a reduction of 370.9 tonnes of CO2 per year.
