Miss Shillingford was very friendly and professional in her on-site assessment and her recommendations were clear and easy to follow. The LED bulb retrofitting was performed in October 2016. Prior to this service, our average monthly electrical consumption was 4447 KWH in the six-month period preceding. Between November 2016 and April 2017, the average electrical consumption has been 2997 KWH per month. Electrical usage at the site is not constant throughout the year and fluctuates due to examinations (where students traffic is higher) and weather. To be sure of the savings, year-to-year consumption was also checked. For the same period, November 2015 to April 2016, consumption was 3863 kWh per month. The savings realized means that the project has basically paid for itself, making this a great investment.
