The 3rd Floor Office extension of the GGF Building at 54 Ayers Street, London consisted of an all glass ‘box’ construction.

Despite the installed glass being high performance solar glass, the occupants suffered from excessive glare from the sun and an uncomfortably hot feeling when near the glass.  It was also recognised that the energy required to cool the space using air conditioning was significant.

Although blinds could have been used to control the glare (they would have little effect on the heat or energy use) they were not practical and also spoilt the panoramic view enjoyed from this top floor office.

It was decided to install a high performance neutral coloured external solar control film that reduced the glare by 80% and the heat by 70%. This film also reduces air conditioning usage by up to 30% so would also pay for itself in around 3 years from reduced air conditioning usage. It is a little known fact that it takes 3 to 4 times more energy to reduce the temperature by 1 degree as it does to heat by 1 degree.

Following the non-disruptive installation the occupants (employees) immediately had their comfort improved with vastly reduced glare and a dramatic reduction in heat.

Nigel Rees, GGF Group Chief Executive said 'We are very pleased with the instant effect on heat and glare of the non- disruptive window film installation. We are looking forward to saving money too!'

Steve Rice, GGF Director of Technical Affairs commented, “It is always pleasing to witness a first class example of how a window film installation can solve existing problems with glazing. This installation has vastly improved the working environment for the staff with a reduction in extreme glare coming through the windows from strong sunshine. Secondly applying window film has made the GGF Building more energy efficient, something that is always high on our agenda. The finished job looks superb and I am pleased a GGF Member company from the Window Film Group undertook the work.”

The corresponding energy analysis showed that more than 125 kWh of energy (£15) would be saved per square metre of glass which relates to the short payback time. With an expected lifetime well past 10 years this type of solution provides a high performance for many years to come.
