Humidification saves energy
The energy performance of commercial properties has been recently under strict government legislation, both in the UK and Europe, in a move to reduce emissions. According to the Committee on Climate Change, 37% of total UK greenhouse gas emissions are from buildings. As such, energy management is increasingly an even bigger concern for building and facilities managers. Andie Chessun, national sales manager UK and RoI at HygroMatik, discusses how an adequate adiabatic humidifi cation can help make buildings more energy effi cient by managing the ongoing cost of long term reliability of HVAC systems.
F
rom 2018, it will be illegal to rent out any of the UK’s 1.8 million non-domestic properties that perform below an E rating under the Energy Performance Certifi cate (EPC). Following an EU Directive on EPC, whenever a property is constructed, rented out or sold in the UK, a certifi cate must be provided to show the energy effi ciency rating of the property, accompanied by recommendations on how that performance can be improved. When it comes to larger organisations, they are also required to undertake energy audits to cover both their buildings and wider energy use, under the Energy Savings Opportunity Scheme (ESOS), regulated by the Environment Agency.
Heating, Ventilation and Air Conditioning (HVAC) systems represent around 60 per cent of the energy used in commercial properties in the UK. However, one thing that is frequently disregarded is the energy waste generated by overheating in the fi rst instance. This waste can be attributed to some HVAC systems missing adequate control systems and thermostats, and in other cases, rooms that do not require enhanced heating
and cooling. For building and facilities managers, installing a humidifi er in collaboration with the air conditioning system can in the long run be a cost eff ective solution, meet and exceed current government legislation, while answering the renters’ needs.
Commercial buildings host a variety of organisations from
diff erent sectors, each with their own particular humidifi cation requests for precise, reliable and low maintenance solutions. When considering rising energy costs, environmental concerns and companies’ requirements, adiabatic humidifi cation is an ideal and eff ective solution to tackle these issues. Off ering precise humidity, they provide considerable energy savings by negating the need for steam and gas. And the units are not only easy to install and retrofi t but also easy to operate and maintain.
While isothermal humidifi ers generate vapour by boiling water, requiring an external source of energy to modify the state of the water, adiabatic systems take heat energy from the surrounding air to create humidifying mist without the need to
