Hidden treasures: Energy efficiency in hospitality

t-mac outlines some of the energy efficiency success stories our clients have enjoyed as a result of our collaboration on their utility monitoring and metering systems.

Slicing costs

The COVID-19 lockdown has severely dampened the cash flow of most businesses and cost-cutting is now a hot topic in boardrooms up and down the country.

Fortunately, rather than having to radically change their approach to business, many firms have the potential to significantly increase their profit margins by improving the way resources are already being utilised.

Business models that rely on being spread across multiple sites, such as those in the retail or hospitality sector, can benefit most from adopting a culture of efficiency that can be scaled to cover all of their facilities.

The restaurant industry can be unforgiving in terms of continued solvency and margin for error when it comes to cash flow, in fact a 2017 study from Forbes showed that nearly 1 in 5 fail in the first year. As such, business leaders in the food service industry are behoved to ensure that their sites and team are equipped to utilise resources as efficiently as possible.

Unfortunately, restaurants have developed an unenviable association with waste due to the sheer amount of food products that are binned at every service. However, there are many ‘invisible’ resources that restaurants must engage with that can provide an arena for sustainability strategies and culture to permeate.

One of our clients, a national pizza chain, recognised that while food wastage was largely subject to consumer preference and hygiene standards, there might be potential for savings elsewhere.

By applying a comprehensive sub metering scheme to identify areas of inefficiency and waste, combined with condition monitoring, temperature and light levels specifically, and a carefully thought out control strategy, including HVAC and lighting, have yielded annual savings of nearly £4000 – and that on a single site!

The increased monitoring capabilities also led to interesting discoveries in terms of breaches of professional values such as fridge doors being propped open, managers opening for staff out of hours and staff staying overnight unauthorised!

Previously these behaviours went unreported and, subsequently, unchecked; however, armed with this data, leadership were able to take appropriate action to prevent them in future. In addition, combined with t-mac’s offering, managers now receive alerts in real-time pertaining to issues like these. While this may seem slightly invasive, it is actually empowering business leaders to make better decisions to the benefit of team members, customers and shareholders.

Park your assumptions

Another t-mac client wanted to explore the possible savings they could make within the infrastructure of a parking facility under their management.

The primary avenue for this exploration was the facility’s lighting system, what initially began as an upgrade to the light monitoring capabilities of the site. This soon became a site-wide LED retrofit.

After comparing the gathered data for both lighting types, and noting the increased efficiency of the new set-up, the client also implemented a control strategy to further compliment these changes.

All told, the weekly lighting cost in the facility dropped by over 75% from £593.63 to £140.22, meaning that if these costs remain static they will save over £23,000 per annum.

As lockdown accommodations shift, opening hours are liable to change as well. The remote nature of these set-ups affords the flexibility and control necessary to ensure that resource use can be tailored accordingly. The value of such control only becomes more palpable when weighed against the possibility of a second wave of COVID-19, anticipated to arrive with winter and colder weather.

These clients are only two examples of the bespoke, IoT empowered metering, and control solutions t-mac specialise in facilitating. We can also oversee the replacement of defunct or inefficient equipment in order to create a comprehensive road-map to improve utility efficiency.
