wimmers at Chipping Norton’s award winning outdoor Lido have been enjoying the great outdoors and dipping into a pool that’s heated by Dimplex low carbon heat pumps, following a £140,000 grant-aided refurbishment.

The popular community facility in the heart of the Cotswolds was rescued from the threat of closure by a campaigning group in 2003. It’s now operated as a charity, with high profile supporters including journalist and TV presenter Jeremy Clarkson and has Prime Minister David Cameron as its patron.


Energy use has always been a major cost at the Lido and the trustees have now completed a major two-year programme of works to help reduce consumption and improve energy efficiency. The refurbishment involved stripping out the plant room to install a Dimplex ground source heat pump system, a UV water treatment system as well as 60 solar photovoltaic (pv) panels on the roof to help provide power as well as an income out of season.


The 45kW Dimplex ground source heat pump was installed by Dimplex


partner Ecovision and it draws heat from nine 120-plus metre deep boreholes drilled in the car park. The additional electricity demand of the heat pump is offset by the solar pv panels on the changing room roof which are capable of generating up to 10kW of electricity. The energy generated can also be fed back into the national grid, providing extra income for the Lido thanks to the Feed-In tariffs.


Energy consumption will be monitored and evaluated closely following a first full season of operation and early indications are very positive, says trustee Clare Jarvis. “We haven’t calculated the actual savings yet but the Dimplex heat pump system is certainly working well and we know our energy costs are significantly reduced.”


Chipping Norton Lido is also receiving national acclaim as a successful example of a pool being taken back into community control. It was featured in a case study in a new report commissioned by the Amateur Swimming Association and the trustees have given support and advice to community groups in other parts of the UK where pools are under threat of

ENERGY EFFICIENT DIMPLEX AIR CURTAINS CAN HELP HIT CRC TARGETS


W


ith the government’s CRC Energy Efficiency Scheme now in effect, large organisations across the public and private sectors are actively looking for ways to reduce their energy consumption, and Dimplex air curtains can help, by creating a stream of fast- moving air that stops treated air from escaping through open doorways. The scheme, formerly known as the Carbon Reduction Commitment, is mandatory for large organisations and aims to improve energy efficiency and cut carbon emissions by rewarding organisations for reducing energy use. Specifying air curtains, or upgrading them to more efficient units, can offer a fast and


easy way to reduce the energy required to maintain a comfortable indoor environment.


Doorways can be one of the biggest challenges to heating or cooling commercial premises and air curtains offer the perfect solution, providing an invisible curtain of air to separate internal and external environments when access points are open. They are a relatively low cost yet effective way to increase the efficiency of the whole HVAC system, maintaining comfort and saving energy, reducing whole facility running cost as well as carbon emissions.


Dimplex air curtains are easy to retrofit, as the manufacturer offers both recessed and surface-mounted models. Alternatively, the units can be installed at the same time as the air conditioning or heating system, for a complete effective HVAC solution. To further reduce energy use, Dimplex air curtains are supplied with a built-in Building Energy Management System (BEMS) interface as standard and they can

also be controlled via timers, presence detectors and temperature controls, which together improve the overall performance of a heating or cooling system. For example, efficiency can often be improved by linking the operation of air curtains to other HVAC equipment either directly or via suitable BEMS links to avoid conflicting operation and improve overall system efficiency.


With many organisations now considering how to reduce carbon use, enhanced products and new technology will play an increasingly important role in achieving lower emissions. Dimplex has a full range of air curtains that can all have a positive impact on carbon emissions wherever fitted, from the CAB and DAB ranges installed over doors of 3m or 4m respectively, to the prestigious ARC designer models and heavy duty IAB range for large industrial premises.
