ENERGY SAVING
Being energy conscious needn’t cost the earth
Paul Lawrence, managing director of Aermec UK, reviews the industry’s approach to energy effi ciency and more sustainable heating and cooling solutions.
G
oing green and investing in lower carbon footprint solutions is often perceived as having a high price tag attached, but when it comes to energy management the opposite is true. Using energy effi cient equipment can result
in signifi cant savings. The HVAC industry has made measurable eff orts to improve the effi ciency of equipment. Products and systems are working harder and smarter and the Internet of Things (IOT) will open up many more possibilities. Every sector is under pressure to minimise
its environmental impact, boost effi ciencies whilst addressing reductions in the overall costs of ownership. It’s a tall order, but the HVAC industry is embracing the challenge enthusiastically, many of the key players are leading the way and we only have to look at the many award entries to see innovation at its best.
The message is getting through and motivating more businesses to take action and integrate energy saving into their business operations. For many HVAC manufacturers, their impact
on the environment has always played an important role in research and development well before climate change became a hot topic. They are continually investing in R&D and looking for solutions that are environmentally

benign, aff ordable whilst delivering the effi ciencies end users demand, reducing dependence on fossil fuels and off ering a more sustainable approach. Chillers, air handlers, heat pumps,
condensers, compressors and fans as well as a wide variety of peripherals can be found in many industries and applications. From heating and cooling commercial buildings to cooling for injection moulding, precision-controlled environments in the pharmaceutical industry to heat management in mission critical data centres, our industry serves them all. Taking a holistic approach and changing the way machines operate, upgrading them to maximise effi ciencies, (for example switching from fi xed speed to variable speed compressors) and even changing the water temperature – increasing the water temperature can be more energy effi cient - can have a considerable impact on how HVAC plant and equipment
are used across a wide range of applications and the savings that can be achieved in energy and costs.
The dilemma for many businesses is whether to replace or repair HVAC plant. Either route requires capital expenditure. Replacement is not always the right route to take. Investing in an appropriate Building Management System (BMS), having a good PPM and exploiting advances in components can all have a positive impact. However, for aged equipment, it may not be cost eff ective to maintain plant or achieve the effi ciencies required; taking the opportunity to invest in the latest technologies
