Temple Sutton Primary school and Nursery
Southend-on-Sea Council apointed Dr Terence Lewis (Founder of Energyst consulting) to advise and assist its aim to increase energy efficiency and reduce its carbon footprint and improve air quality while reducing ongoing fuel costs across the Borough.
The out come of an in depth feasability study idendified that a holistic aproach to based on Conservation, Generation andEnergy management would deliver the best results.
1: Fabric First. New double glased windows and doors were installed along with roof cavity and pipe work insulation
2:LED Lighting throughout the school.
3: New 250. kWBiomass Boiler installed a lead heat generator to the existing Gas boilers. the project included smart heating controls, Optimisations to the Building Management System (BMS)
4: Sustainability education for Teaching staff and pupils.
Treco won the competitive tender for the Biomass Supply installation The existing plant room where the plant and fuel store were to be installed were subterranean, this meant special attention when it came to delivering plant as the stairs to access the plant room were too narrow. The boiler and thermal store had to be craned into place through a hole that was created for the fuel store roof. A bespoke weatherproof hatch also had to be designed to allow for tipped wood-chip deliveries. Thought also had to be given to how ash would be removed from the boilers as again the stairs weren’t suitable. A bespoke vacuum system was designed to deal with this.
· Project included
· 250kW Lindner & Sommerauer wood chip biomass boiler
· Fuel consumption: In the region of 95 tonnes per annum
· Fuel cost saving: In the region of £2,000 per annum
· CO₂ saving: Approximately 50 tonnes per annum
· RHI payments: - A project of this size would gain an approximately £17,000 every year for 20 years, index linked to inflation
· Total project cost £120,000 = ROI ,6 years (combining RHI income & fuel cost saving)
Solar PV 207Kw
Temple Sutton Primary School – 207 kWp = approximately 180,00 kW of free energy per year. This is in addition to income from feed in tariffs As this site had an export limit of 100kWp imposed by the DNO, we installed an Argand Export limiting device which monitors the level of export and can shut off individual inverters in sequence to ensure the limit is never breached.
Dr Terence is proud to have been involved with the inception for Southend councils Lo Carbon renewable energy program. It is about “Making a Difference” and leaving a lasting legacy. Such as the all weather sports field at Temple Sutton financed through green energy savings.
