Why better HVAC boots retail sector energy efficiency

Pressures on retailers are greater than ever in 2021. Managing heating, ventilation and air conditioning (HVAC) and attendant energy costs shouldn’t be an added source of concern. In our latest blog, we take a closer look at how Hodgkinson Bennis can help boost retail sector energy efficiency through better HVAC. By fitting and maintaining better HVAC systems and controls, Hodgkinson Bennis is well-placed to help achieve retail sector energy efficiency.

Retailers are always under pressure – and in 2021, these pressures are greater than ever. The return of shoppers to the high street after lockdown has added new concerns; among other measures, Covid safety means that retailers must be aware of airflow throughout their premises. But managing heating, ventilation and air conditioning (HVAC) and attendant energy costs shouldn’t be an added source of pressure. The good news is that generally speaking energy costs are a small percentage of turnover in the retail and distribution sector. And in many businesses, saving energy is an easy win. In this blog, we’re taking a closer look at how Hodgkinson Bennis can help boost retail energy efficiency through better HVAC.


Start with a good HVAC system

Research by the Carbon Trust shows that three areas together account for around 80% of the retail sector’s average energy spend. These are HVAC, cooled storage, and lighting. Other companies are best-placed to improve the latter elements of retail energy efficiency through better insulation, low-energy lighting, and modern refrigeration equipment. Here at Hodgkinson Bennis, we can focus on HVAC.


For many retail businesses, the different elements of HVAC can operate in opposition to each other, rather than working coherently. A new boiler and HVAC equipment is one obvious place to start reducing long-term retail energy usage. We are experts at fitting and commissioning new plant while allowing retailers to maintain service with minimum disruption. We can also outline incentives to fit new equipment. The government’s Non-Domestic Renewable Heat Incentive is designed to subsidise commercial businesses which install a biomass boiler. Smaller and medium-sized establishments may also qualify for a Carbon Trust loan to install new energy-efficient equipment.


We may also be able to redesign a hot water system. As water is a metered and controllable resource, it’s possible to save on both water and energy costs by implementing inexpensive efficiency measures. Rationalising pipework will save people from having to run the water in bathrooms until it becomes hot. And for stored hot water, we can help to set appropriate hot water temperatures. The optimum temperature is 60ºC, which is adequate to kill Legionella bacteria and is sufficiently warm to use.


Retail sector energy efficiency comes through control

One crucial area for retail environments is maintaining the right temperature during opening hours. Retail operations often overheat stores in winter to accommodate staff in short-sleeved uniforms, while customers are wearing warmer clothing. This can be a particular problem for food retailers with open refrigerators, or a shop that keeps its doors permanently open. At other times, especially during transitions between seasons, heating and cooling systems operate in conflict with each other. One solution is a temperature ‘dead band’: heating switches off once the temperature reaches 20ºC, but cooling comes in only when the temperature exceeds 23ºC.


Hodgkinson Bennis can fit the very latest control equipment to address all these problems. For larger stores, it’s worth considering a comprehensive building management system (BMS) which can reduce energy costs by over 10%. A BMS is a network of heating and ventilation controllers that are interfaced with a computer. For smaller stores, a compensator automatically regulates heating temperature based on outside conditions, while an optimum start controller learns how quickly the building reaches the desired temperature. For even smaller operations, a simple timer switch can even cover times when staff members are replenishing stock outside regular opening hours.


Planned preventive maintenance and energy management pays for itself

We’re also experts at managing systems so they operate at peak efficiency. For boilers, we can devise a servicing schedule, which will include annual safety checks for gas equipment. We’ll make sure that heating and hot water are distributed correctly, by maintaining pipework. Proper maintenance will minimise the risk of a major system malfunction. But should you need emergency repairs, we’re on hand for those too.


As for broader energy management processes, it’s essential is to make sure that everyone understands its importance, and the benefits it brings. Commitment to energy efficiency has to come from the top and should be backed up by a personalised mission statement and energy policy. All staff are important in saving energy; motivate staff to feel their efforts make a difference, and that energy saving isn’t too technical. As an energy-saving programme gathers momentum, it will be possible to track progress and highlight energy savings. It’s vital to set ambitious but realistic targets; while most UK businesses could reduce energy consumption by 10-40%, perhaps start with 5% per year. And just as maintenance is crucial for boiler equipment, resolving any housekeeping and other maintenance issues early can avoid expensive problems later on.
