Sustainability features can be found on all three of our campuses:
All of our food outlets on campus offer vegetarian options every day, and all delivered catering has vegetarian and plant-based menus.
The Essex Business School building in Colchester is the UK's first zero-carbon business school building and houses our Accounting, Finance and Management and Marketing groups as well as over 2,000 students and staff.
It has been estimated that the design of the building reduces emissions by 18% as a result of solar panels, making use of natural light, heat circulation.
The central courtyard is open to the sky and forms a water garden, collecting roof surface rainwater, which is in turn used to irrigate the winter garden planting.
The building has been orientated to make maximum benefit of solar energy, both through passive heat gains and PV energy.
The 500sqm solar array offsets 47.9 tonnes of CO2 annually generating enough electrical energy to offset over 20% of the site's carbon emissions.
At the University of Essex we believe in responsible construction and refurbishment.
All our new build and refurbishment projects are assessed for sustainability performance and impacts, with BREEAM ‘very good’ as the minimum rating expected for major building projects.
Any new building must incorporate in 15% renewables, this is increased where funding allows.
We have a preference to invest in FSC certified furniture that complies with our ethical purchasing commitments.

Installing solar photovoltaic panels (PV) across our eligible roofs has already proved to be a cost-effective approach to reducing our reliance on energy imports. Panels have already been installed on many of our roofs, including The Albert Sloman Library and Sports Arena, enabling the University to cover 8% of its electricity needs. In the next three years, we plan to install solar photovoltaics on the remaining eligible roofs to meet an additional 10% of our electricity requirements.
Project | Purpose and Benefits | Status | Energy Savings kWh pa | Carbon Savings (TCO2e) pa |
Adjustments to heating/cooling temperatures and timings | The University have adopted and aims to maintain a comfortable temperature set point (as set out in the Energy Management Policy) during the building’s predominant occupancy hours, to provide a suitable environment for its occupants and to maximise energy reduction, cost savings and our commitment to being net zero scope1 and 2 carbon emissions by 2035. | Phase one complete with changes made to all controls where currently possible. Phase two will be determined in line with relevant future projects. | 3,483,447 kWh | 655 |
Sub-metering | Sub-metering of individual building will allow us to monitor utility usage and take remedial actions for wastage. | Detailed audits completed. | 2,500,000 kWh and 9,000m3 of water | 509 |
Smart TRV trial and roll out | TRV stands for Thermostatic Radiator Valve. Smart TRVs allow for room-by-room control of radiators, to help avoid heating empty spaces. | Trial has been completed. Trial has revealed savings of approximately 30% on energy use for heating. | 8,210 kWh | 2 |
Lighting upgrades to LED | Upgrades to replace traditional lighting to LED bulbs across three campuses to reduce energy use by 40%. | LED lighting has been upgraded across two sites in Colchester and three sites in Southend. |
514,259 kWh | 107 |
Occupancy sensors | Aims to link Smart TRVs. This monitors room occupancy to determine whether the heating should be fully on or not. | Trial of sensors implemented in selected rooms. Data will be reviewed to understand the benefit and value in a wider roll out. | To be confirmed | To be confirmed |
Building Management System (BMS) upgrades | Current SERCK BMS systems will be replaced with TREND systems in several locations, allowing greater control of energy management. |
Audit work is in progress. | 666,667 kWh | 122 |
Comfort cooling sensors | Presence Infrared (PIR) sensors installed to AC units to switch off/on heating based on room occupancy. | 38 units have been installed in Constable Building (Kaplan). | 86,656 kWh | 18 |
Temperature monitoring sensors (Rab Butler Building) | Sensors installed on each level to accurately measure the temperature within the building. | These sensors provide real-time data to Building Management Systems (BMS) to ensure occupant comfort whilst maintaining efficient control. | 4,318 kWh | 1 |
Tap flow restrictors | Devices that limit the flow of water from a tap. | Audit work is in progress to identify the flow rate. | To be confirmed | To be confirmed |
Shower head replacements | Installation of eco shower heads with a reduced flow rate of 8 litres per minute. | 1200 units have been installed in South Courts. |
28,290 m3 of water | 40 |
Window upgrades to 1960's estate (single glazed) | Single glazed windows will be upgraded to double glazed. | In development of an agreed design standard for window upgrades. | To be confirmed | To be confirmed |
Solar PV installation | This project contributes to onsite renewable energy generation at Colchester Campus. |
Panels now installed on: Computing HSC SSRC Library lower level 2001 Ivor Crewe Network Building |
559,600 kWh | 116 |
Roof replacements and insulation | To identify areas where roofing needs replacement or further insulation to help reduce 20% of energy wastage. |
Phase one: 1100m2 of roofing on the 1960s central campus buildings underway (August 2023, due for completion 13 October 2023). Phase two: plans are in development. |
265,615 kWh | 49 |
Student Union (SU) shop fridge replacements | Installation of doors on fridges to reduce energy wastage. | Completed July 2023. | 100,000 kWh | 21 |
AC unit compressor controls | Retrofit solution on AC units to reduce the compressor speed. | Audit work in progress. | To be confirmed | To be confirmed |
Building Decarbonisation Plan | To identify University buildings for heat decarbonisation. | £181k in funding awarded in Summer 2023 through the Salix Low Carbon Skills Fund towards the costs of development of the Decarbonisation Plan. | To be confirmed | To be confirmed |
Hand dryer replacements | To identify the energy saving opportunities through measuring the current wattage and drying time. | Audit work to be commissioned. | To be confirmed | To be confirmed |
HVAC Upgrades | HVAC systems stands for heating, ventilation and air conditioning systems. This project will identify existing HVAC system conditions and energy and carbon saving options. | Audit work to be commissioned. | 404,000 kWh | 84 |
