The Constellation Trust is a group of seven primary schools; two secondary schools; and one alternative provision school located in East Yorkshire, each committed to working collaboratively to provide the highest quality educational experience for pupils.
As a village college, the school is at the heart of its local community, providing learning, sports and leisure amenities for its locality, and recognised its responsibility to conserve water. The school engaged Zenergi to carry out a water survey to identify opportunities for reducing water consumption.
Analysis of the meter readings found that the school is consuming 1,000 litres of water every hour throughout the night when the school is empty.
The survey found that 55% of water usage was consumed when pupils weren’t on site.
Low-cost measures were identified that cumulatively should lead to annual cost savings of approximately £16,176.
The savings identified represent an 80% reduction in the current financial cost of water.
Water benchmarking analysis was carried out, comparing the annual m³ of water for each pupil to set benchmark figures. It concluded that Linton Village College is using an excessive volume of water expected for a secondary school.
Analysis of the meter readings found that the school is consuming 1,000 litres of water every hour throughout the night when the school is empty, suggesting a water leakage. Throughout the 24 hours of the survey, 28,800 litres of water was used by the site, 55% of which was consumed when the pupils weren’t on site. Our calculations estimated that around 6,200m³ of water is leaking from this site annually, which equates to 78% of the site’s total annual consumption.
The survey investigated the causes of the leakage and identified they took place in the toilets and urinals. For a cost of no more that £2,000 to fix the issue, the payback period would be around one to two months.
Additional low-cost measures were identified that cumulatively should lead to annual cost savings of approximately £16,176 with an investment cost less than £2,500, giving a payback period of two months. This would be a 80% reduction in the current financial cost of water.
In line and to support our Environmental and Sustainability Policy, we undertook energy and water surveys. The surveys suggested easy and cost effective solutions across key sites where energy and water losses were identified. Our investment in water surveys was very beneficial to the Trust to establish our benchmark and identify low cost saving opportunities.

Glenmorangie sought a focused solution to improve energy efficiency and reduce costs. By working closely with the team at Zenergi, the strategic building optimisation resulted in a 59% reduction in electricity consumption and a 52% reduction in gas usage.
Danes Educational Trust selected Zenergi as its trusted carbon reduction partner, securing £166,000 in grant funding for heat decarbonisation and energy efficiency upgrades.
Leigh Academies Trust adopted Zenergi’s Zen Flex Bespoke product to take advantage of market movements by purchasing a volume of energy up front, while also trading on the day-ahead market to spread the risk of the volatile markets.
Zenergi’s services for PR Associates keep schools up to date with energy compliance, as well as driving energy efficiency to reduce costs and carbon emissions.
Zenergi supports Shropshire Council’s vision to stabilise and progressively reduce its environmental footprint., with the provision of Display Energy Certificates, which it has carried out for the Council for over 10 years.
Zenergi carried out the delivery of commercial Energy Performance Certificates for 52 properties in Reading to meet compliance with the Minimum Energy Efficiency Standards.
School Business Professionals are increasingly challenged to balance shrinking budgets and escalating operating costs. However, energy is an area that offers opportunities to protect school budgets through a competitive tender process that proactively secures prices that take advantage of low wholesale market positions where possible.
We started working with Windmill Care when we successfully negotiated good tariffs for gas and electricity contracts for the group’s three care homes. But, before they went live, Windmill Care’s incumbent supplier identified a billing issue.
