Energy projects

Investment in energy saving projects

The Sustainability Action Group hold a register of projects, devised in conjunction with the Carbon Management Plan to ensure energy conversation practices and measures will be implemented to reduce our Carbon Footprint and conserve environmental resources.

The university’s energy team is active around the campus, carrying out specific projects and monitoring our use of energy in all areas.

Below is a list of ongoing projects as well as those which have been completed and which are already making a difference.

Current Projects

Good House Keeping

Currently continuously monitoring timetables, optimisation settings and heating set points.

Upgrade Metering, Monitoring and Targeting System

Existing metering system investigation and improvement.

Student Green Champions

Student Involvement. At the latest Freshers event, a total of 59 students were recruited. The Student's Union is now involved with planning on how to take the initiative forward. Refresher plan also to be drafted for existing staff Green Champions.

Working with Wrexham Council & possibly Wrexham Maelor Hospital

Wrexham County Borough Council met up with the Energy Team in December to discuss Employee Awareness to Reduce Energy Consumption. Plans in place to meet also with Wrexham Maelor Hospital in 2014, the biggest three  Wrexham employers coming together to reduce carbon emissions, energy consumption and energy costs.

Completed Projects

Two major carbon reduction, Salix Funded projects took place June to October 2013 for lighting and heating to further improve our carbon reduction targets.

Salix Finance Ltd delivers 100% interest-free capital to the public sector to improve their energy efficiency and reduce their carbon emissions. Salix was established in 2004 as an independent, publicly funded company, dedicated to providing the public sector with loans for energy efficiency projects.

Lighting Refurbishment

Replacing existing lamps with lower wattage, more energy efficient, T5 fittings.

Upgrade of Library LED & T5 Lighting Project - bringing environmental benefits along with saving money.  Lighting in the library is in use for many hours throughout the year hence was of particular interest for a modernisation program.

The work was completed out of normal operating hours, which ensured minimal disruption to staff and students.

The project involved a combination of LED and T5 lamps, replacement and conversion fittings. This entailed replacing the primary working components within the light fixtures (i.e. newer energy-efficient lamps and ballasts), redesigning fixtures for a different configuration of lamps, ballasts, and reflectors and replacing existing fixtures with new, more efficient ones.

Proposed savings achieved will reduce our library lighting energy costs by 40-60%. In addition, the lighting retrofit project will save on maintenance costs, because the replacement lights are used and their components have a much longer lifecycle than the previous ones. Additional savings will come from daylight sensors so that lights can automatically turn off when daylight gives sufficient brightness in certain areas.

The project completed by the end of August 2013. The outcomes beyond energy savings will include improved student and employee workspace areas, brighter reading conditions, increased safety and accident prevention and improved customer satisfaction.

Insulation of Heating and Hot Water Pipework & Fittings - Plas Coch Site, Wrexham.

The project started end of August 2013 and was completed end of October 2013. It consisted of thermal insulation to reduce heat loss which in turn will improve the performance of the heating system and reduce gas consumption, thus reducing the University’s carbon emissions.

The work was carried out within the Plas Coch Campus in the ducts and main boiler house and comprised of the supply and installation of thermal insulation of valves, flanges, heat exchangers and pipework within the low/medium temperature hot water heating system (80 - 120°C) and duty hot water system.

Project Update:  In line with the Heating Policy the heating has been switched on since mid-October. The monitoring of timetables, optimisation settings and heating set points have already been altered/reduced in this period alone as the heating system is performing exceptionally well. Data is currently being analysed.

Salix was so impressed by our project that they are currently using it as a case study presenting to Town & Community Councils.

Other recently completed projects

Revamp of Main Entrance Flower Beds at Northop

Northop’s New Casual makes a great start to brightening up the flower beds at Northop campus. Kim Johnson volunteered her time and effort to inspire staff to donate a whole range of plants including rosemary, lavender, geraniums and begonias. She chose to completely revamp the bed outside the main entrance to Corbishley Hall accommodation in Northop. Kim commented saying “I hope to inspire the students when they return to leave their mark here at Northop to start an edible garden that students and residents will be able to utilise”‌

Water – Colliers Park

Investigations into meter reading billings resulted in disconnection of an unused meter at the end of October 2013. This will result in substantial savings per annum.

Water – Plas Coch Hockey Pitch

A water refund from Dee Valley Water has been refunded in October 2013 for the international hockey pitch’s non-return to sewer allowance.

A 45% allowance has been granted in addition to the current standard 5% allowance already in place making a total of 50% non-return to sewer allowance.

This is effective from 01/04/2011 to 08/10/13 owing to the receipt of the original claim being made in that financial year.

A submeter was installed in August 2012 to enable accurate usage readings to be obtained for a whole billing year and from analysing the hockey pitch’s consumption alongside the main meter figures billed upon from Dee Valley Water, the trade effluent officer was able to complete his assessment. This allowance will be ongoing and reflected in our future invoices.

Electricity Sub Meter - Wrexham Football Stadium

Investigations were completed into meter reading billings, resulting in a refund from Scottish Power.

In December, the electricity account for supply at Wrexham Football Stadium was corrected, as it was confirmed that a previously charged meter was, in fact, a Sub Meter and should never have been billed.

Scottish Power Business Energy Team apologised for the errors that occurred.

Christmas Switch Off

The previous successful Christmas ‘Switch it off’ campaign produced results over the December/January period of an overall electricity decrease of massive 25,805 kWh’s, which calculated at just over 14 tonnes of CO² Emissions.

Staff were again encouraged to switch off lights and unplug equipment during the most last Christmas break.

December alone showed an overall electricity decrease of 27,945 kWh’s, which calculates at a saving of 15 and a quarter tonnes of CO² Emissions.  This is a decrease on last December by 0.4% and an extra saving of over a  tonne of CO² Emissions.
