Towering achievement for assessor

One of the world’s most famous landmarks helped Darren Jones become the UK’s first fully accredited energy assessor for complex Air Conditioning systems.


Mr Jones, from Efficient Air, reviewed facilities at the
Tower of London as part of the reports he had to complete for his accreditation training with CIBSE – the only approved training body.


Some 20,000 systems in
England and Wales which are more than 5-years-old and have a rated cooling output of more than 250kW must have an inspection by January 4 2009.


Mr Jones said his report on the Tower delivered recommendations which were easy to understand while offering the building’s owners the opportunity to make quick, real savings.


He said: “This high profile example shows how quickly the inspection process will pick up and identify a whole host of issues relating to the efficiency of the HVAC plant.


“We have plenty of evidence to show companies that meeting the requirements of the inspection makes sound business sense in terms of the savings and return on investments that can be made.


“We are finding a new attitude among property managers at all levels of wanting to improve the energy rating of the building and having one of these inspections to tell them how to do it.


“Public organisations and private companies such as large banks and retailers will act on Air Conditioning inspections immediately as they will want to be seen to be adhering to their corporate social responsibility policies, reducing their carbon footprint and reducing the impact of heavy energy price rises.”


Mr Jones worked alongside Jeff Walker, Energy Manager of Historic Royal Palaces, the independent charity which cares for the Tower along with
Hampton Court Palace, Kensington Palace, Banqueting House Whitehall and Kew Palace.


Mr Walker said: “We have now met the requirements of a TM44 inspection, and can gain complete control over the HVAC system and reduce our energy consumption by over one fifth”


Mr Jones undertook a survey of the heating, ventilation and air conditioning systems and their controls at the three-storey Waterloo Block which includes the ground floor Jewel House, where the Crown Jewels are on display, a first floor Education Centre and the top floor for offices plus basement storage area.


The building functions 7 days a week with the ground floor and first floor conditioned by 10 Air Handling Units (AHU), the top floor offices heated by radiators and the basement conditioned by another AHU. During 2007 this busy building consumed over one million kilowatt hours (kWh) of electricity and 950,000 kWh of gas.


Efficient Air recommended a series of low cost modifications which it calculates will deliver an energy reduction of  429,430 kWhs (around 22 per cent) and cost savings in the region of £22,370 per year plus a carbon dioxide reduction of 236 tonnes.


Working alongside colleagues from Efficient Air, a leading HVAC energy saving company, Darren has developed a comprehensive methodology for assessing the efficiency of HAVC plant within any type of building.
