Energy Saving

Over the last few decades there has been rapid growth in energy consumption in the public sector and commercial buildings, due to the ever-increasing demands of technology. According to EON ‘five sectors – offices, retail, industrial, health and hospitality – accounted for 71% of total energy consumption’ (1*) how-businesses-can-reduce-energy-bills

ESOS is a mandatory energy assessment scheme, designed for heavy users of energy that have significant overheads. New legislation and sustainability requirements mean that qualifying premises need to meet these standards and be compliant with the Energy Savings Opportunity Scheme (see below). 

GCL can provide multiple smart building services reducing the number of companies you have to deal with, making projects easier to manage. Using one company reduces the number of precious commodities used in the installation processes thereby reducing the environmental impact of the Project and the Services. 
GCL can help cut your operating costs and help you meet your environmental obligations and ESOS compliance.

Smart LED Lighting Systems

Today LED lighting is recognised as being a super-efficient way of saving energy costs; however, when looking at installing new lighting systems, several considerations need to be considered. LED lighting fixtures have been commoditised using cheap imports from China. More affordable fittings often come with exaggerated claims about how long they will last. The advantages that smart lighting has to offer are immense and GCL are experts when it comes to Smart LED Lighting Systems and is an accredited partner to IST, whose systems are amongst the most advanced in the World.

What do Smart Led Lighting Systems have to offer?

Smart Lighting Systems use sensor technology and data analytics that deliver solutions for energy savings, space utilisation analysis and optimisation, asset and employee/visitor locating, lighting control that will increase employee productivity, and more. Third-party applications such as conference room management, hot desking reservation, and Heating, ventilation, air conditioning (HVAC) systems are all made intelligent with real-time data and status of spaces capture. By having a Smart Lighting system installed, you will also potentially be able to take advantage of new technologies such as Li-Fi which will revolutionise the way we communicate in the future.

Better Control and Much healthier Light

Installing intelligent lighting controls will ensure you are not using any more energy than you need to. Detection systems which sense movement and natural light can replace your conventional switches, ensuring lights are turned off automatically in unoccupied spaces, reducing your lighting expenditure.

Cambridge University research has shown that If you ensure that 10 lights around your workspace are switched off every night, each year you could:

  • Save as much CO2 as would be produced by 50 car journeys from Cambridge to London.
  • Reduce your carbon footprint by the same amount as cutting out 25 flights from London to Paris.

Another benefit to smart lighting is being able to offer Circadian Lighting this is the concept that electric light can be used to support human health by minimising the effect of electric light on the human circadian rhythm. In essence, it is an artificial 'sunrise to sunset' which travels through illuminance levels and colour spectrums from a warm colour spectrum (2,700K) to brighter, cooler (6,500K and upwards) and back again. Which provides a more natural environment to work and is proven to improve employee efficiency with less absenteeism and at the same time, making the workplace a nicer environment.

One of the problems with most LED lighting fittings, which is either not even considered a problem or is overlooked is the flickering that often gets worse the more the lights are dimmed. Flickering LED lights can cause headaches and for some people, or more seriously epilepsy for those that are sensitive to this problem. IST's Smart Lighting System is entirely flicker free, and they have Worldwide patents on flicker free technology

Your smart lighting system will:

  • Significantly reduce energy usage
  • Drastically improve LED driver lifespan (the driver is an electrical circuit used to power a LED).
  • Provide huge maintenance costs savings
  • Maintain optimum lighting levels

From Comms cable to lighting cable all on one cable type

GCL's technicians can install the cabling for the lighting system at the same time as the cabling for voice, data, security, and audio visual (AV) everything runs on the same standard, low voltage structured cabling system. There is no need for electrical distribution boards or separate conduits for lighting unlike 230Vac cabling, thereby saving on installation costs.

Building Energy Management System (BEMS):

A building energy management system (BEMS) is a computer-based approach to measuring, monitoring, and managing the performance of building services, such as heating, ventilation, air-conditioning, lighting, and security. By reducing the AC by as little as 1 degree, Celsius could reduce your annual energy bill by up to 8% (2*)

Benefits of BEMS:

  • Coordinate the operation of various systems
  • Complete control over your building environment
  • Closely monitor building energy efficiency
  • Reduce energy consumption
  • Can be integrated with Smart Lighting Systems

Your building's Facilities Manager can use these systems to monitor building energy usage. GCL will provide you with a system that can be accessed from PC's, laptops, and hand-held devices. This will give you quick access to building information in the form of graphs, charts, and reports, allowing you to make informed energy-saving decisions. BEM's systems can also be controlled by your lighting system software that provides new levels of building intelligence. 

Energy Savings Opportunity Scheme (ESOS) Complying with legislation & incentives

ESOS is a mandatory energy assessment scheme for organisations in the UK that meet the qualification criteria. The Environment Agency is the UK scheme administrator..

ESOS (Energy Savings Opportunity Scheme) is a mandatory energy assessment scheme for large organisations in the UK that meet the qualification criteria.

  • Employs 250 or more people
  • An annual turnover over €50m 

Organisations that qualify for ESOS must carry out ESOS assessments every 4 years. These assessments are audits of the energy used by their buildings, industrial processes, and transport to identify cost-effective energy-saving measures

How to Ensure you are Compliant with ESOS?

You can demonstrate that you have made a compliant ESOS assessment by using Display Energy Certificates (DECs), Green Deals Assessments (GDAs), ESOS compliant energy audits or ISO 50001 certification. 

If you do not have an ISO 50001 accredited energy management system which covers all your energy use, you must carry out an ESOS assessment.  To achieve compliance, you need to complete the following steps:

  • Calculate your total energy consumption
  • Identify your areas of significant energy consumption
  • Consider available routes to compliance
  • Appoint an ESOS Lead Assessor
  • Notify the Environment Agency – online
  • Keep a record of how you complied with ESOS

What are the Benefits of ESOS?

ESOS is more than just a compliance exercise; it provides detailed recommendations of where and how to save energy. Whilst the ESOS programme does not insist that you undertake the recommended measures from the audits, it provides businesses with a platform to work from to reduce capital expenditure and improve operational efficiency. 

The information from your ESOS energy audit can be used as the basis for implementing an energy management system (EMS) to facilitate the realisation of the energy-saving opportunities identified. If your system is then certified to ISO 50001 during the next four years, your organisation will automatically demonstrate ESOS compliance. 

ESOS is now in phase 3 – and the deadline for compliance is 5 December 2023.
