University set to reduce energy consumption by 28.46%
Wiltshire-based energy and reduction specialist SMARTech energy have partnered with a university in Oxfordshire to design, develop and deliver energy efficiency solutions through its Energy Efficiency as a Service (EEaaS) programme.
Save Energy. Save Money. Save Carbon.
The university is predicted to reduce its annual energy consumption by 28.46% and carbon savings of more than 13 tonnes.
As an education establishment, they didn’t have the capital to invest – or experience and resource to implement an energy reduction plan and wanted to upgrade their site with innovative building technologies.
Energy Efficiency as a Service (EEaaS)
A zero CapEx finance solution through the EEaaS model has enabled the university to achieve its ambitious sustainability targets to save energy, save money and save carbon.
SMARTech energy provided 100% of the investment to develop a strategy to design, integrate, install and deliver a comprehensive portfolio of energy efficient technology upgrades – which has been designed to achieve the most efficient energy savings.
Managed and Trusted Energy Management Partner – with Guaranteed Energy Savings
SMARTech energy delivers and manages energy efficiency and savings for medium and large organisations across the UK through its (EEaaS) Energy Efficiency as a Service programme.
We partner with customers on long-term (10 year) contracts in order to create a bespoke energy reduction strategy. Being in a managed partnership with our customers guarantees the success in reducing energy consumption and consistently ensures that we save energy, save money and save carbon.
Energy Reduction Technology
Energy consumption across the university site was measured through the use of energy monitoring equipment. This was installed to identify energy usage on the main incoming supply and on key assets to record at least 50% of the energy usage to minute-by-minute data.
The technologies installed are then combined in order to achieve greater savings. The strategy for the university site included:
- LED Lighting
Replacing old systems with more energy efficient ones and implementing SMART lighting sensors and controls across the site.
- Voltage Optimisation
The voltage optimisation (VO) strategy involves the installation of a VO unit on the site’s main incoming supply. The role of the unit is to optimise the voltage supplied to the site. This minimises voltage spikes, helping to prolong the lifespan of the electrical equipment. In addition, reduced voltage leads to an overall reduction in energy consumption.
- SMART Refrigeration
The installation of Chilled Unit Energy Savers (CUES) upgrades the existing thermostat located inside of the existing evaporating units. It replicates the thermostatic properties of the foods stored inside the chillers. CUES allows the refrigeration system to optimally adjust its refrigeration cycle to cool the stored food, not the ambient air inside the cold storage areas.
- SMART Switch / Baseload reduction
By combining SMART Switch and Baseload Reduction we are able to manage and minimise the out of hours through process changes and SMART Switching. Called ‘SMART Switching’, the controlled assets include air conditioning compressors, trace tapes and external lighting.
- Motor Optimisation
The motor optimisation strategy includes the optimisation of Variable Speed Drives (VSD) on the motors in the kitchen air handling unit (AHU). A variable speed drive (VSD) controls the speed and torque of a motor by converting fixed frequency and voltage input to a variable frequency and voltage output. System performance can be greatly improved by controlling speed to precisely match the load – while also extending their usual life.
Carbon and Financial Energy Savings
The carbon and financial savings made will help to support the university to be more environmentally friendly and financially sustainable and this, together with improvements to the building will have a positive effect on both the students and staff.
