Wiltshire-based SMARTech energy partnered with UTC Swindon to reduce their energy consumption, costs and carbon through its Energy Efficiency as a Service (EEaaS) programme.

Measured and verified energy reduction results reveal average energy savings over 2 years of 30.46%.  This reduction will also avoid more than 671 tonnes of CO2 emissions over the terms of the contract.

SMARTech energy developed a comprehensive energy reduction strategy to achieve these savings and with the EEaaS partnership now in it’s third year of a 10 year programme, this is set to help the college to save energy, save money and save carbon.

IPMVP measured and verified energy savings for UTC Swindon

With three commercial options available, SMARTech energy have made reducing energy consumption and going green very simple.

UTC Swindon took the zero CapEx, shared savings approach to energy efficiency.  It’s where the energy savings pay for the installation and maintenance of low-carbon technology products – enabling organisations to implement an energy reduction drive and improve costs, carbon and sustainability.  There’s no upfront costs, leasing or risk and the client typically receives 30% of the savings.

Through this model, its enabled the UTC to execute a fully-funded energy efficiency programme with SMARTech energy managing the strategy to design, integrate, install and deliver a comprehensive portfolio of efficient building technologies – from LED lighting, base load reduction and motor optimisation.

Throughout the 10 year programme, SMARTech energy will be responsible for managing the technologies and proving the energy savings year on year.


Energy Consultancy

An initial site survey and discussion of opportunities to reduce the site’s energy consumption, enabled SMARTech energy’s team of expert consultants and engineers to design an energy monitoring system and install it.  This gives minute by minute data to help understand the site usage profiles across various equipment and loads on site.


The data analytics produced from this, then helped to form the basis of an energy reduction report.  Through factual data, it’s this report which focuses on preventing energy wastage and provides recommendations for improvements, either through updates to energy efficient technologies or changes to process.

Energy Consultancy – Strategy Report

The Strategy Report details and provides reasoning on areas where energy savings can be achieved, such as settings, setpoints, scheduling and control systems.  It’s this report which is fundamental to achieving the goals of the programme and for the measurement and verification process to be fully realised.


The installation by our team of electricians and engineers of the recommended energy conservation measures (ECMs), guarantees to reduce energy consumption and optimises the energy performance and operating conditions across the site.

Tech Stack

The long-term energy reduction strategy with UTC Swindon includes (but is not limited to) LED lighting upgrades, motor optimisation and baseload reduction.

Project Management

Continuous project management of the energy reduction programme ensures the success of all elements of the partnership; including management support, energy monitoring, plus through the use of visuals from powerful dashboard analytics – which provide alerts and which continue to guarantee results.

IPMVP – Monitoring and Verification

Energy savings are measured and verified using an internationally recognised Performance, Measurement and Verification Protocol (IPMVP). This protocol is used to measure and validate the performance of energy management and reduction calculations.

First M&V Savings report:

  • End of year one of the EEaaS programme
  • Energy savings 43%
  • Carbon savings 1.976 Tonnes

The measurement period for the first measurement and verification analysis was from 1st July 2021 to 30th November for electricity.  The independent variables are heating degree days (HDD) and cooling degree days (CDD) for each month for the AHU.  No independent variables were used for the LED lighting, with a sample based analysis approach employed.

Second Year Savings report:

  • End of year two of the EEaaS programme
  • Energy savings 33%
  • Carbon savings 23.5 Tonnes

The independent variables applied are heating degree days at 18  ̊C, cooling degree days at 15.5  ̊C and school hours.  The data for two weather related independent variables were collected from the website www.degreedays.net as stipulated in the M&V plan.  The independent variables on school hours is calculated based on the term time schedule available on the school’s website.

Third Year Savings report:

  • End of year two of the EEaaS programme
  • Energy savings 28.2%
  • Carbon savings 46 Tonnes

 The independent variables were based on the same variables as above.

Combined average for electric savings equates to 30.46%

The following graph provides a visual understanding of the electrical energy savings realised at the site and represents an average from the savings achieved over the past 2 years.  The top line of the graph represents the adjusted baseline energy usage of kWhs – if upgrades to low-carbon technologies were not carried out.  The bottom line on the graph is the actual measured energy usage on utility bills following technology upgrades.  These energy savings are measured and verified using an international protocol (IPMVP).

UTC Swindon

Ongoing Support

On-going support of UTC Swindon’s energy management strategy ensures that the site’s energy performance and operating conditions are optimised. This support guarantees continuous energy savings.

IT Support

Energy dashboards provide our customers with a real-time reporting tool which tracks the effects of energy saving efforts.

This information allows SMARTech energy’s consultancy team to constantly analyse and optimise technologies at the site.


Managing a client’s energy reduction strategy on a long-term partnership leads to guaranteed, proven and measured ongoing energy savings.  UTC Swindon is one of more than 40 education sites within the Activate Education Trust.

SMARTech energy’s management partnership with UTC Swindon follows the successful roll out of the Energy Efficiency as a Service (EEaaS) programme at other UTC sites across the country.

The savings achieved through this energy management partnership demonstrates the Trust’s commitment to improving sustainability, costs and carbon across the group.
