Energy Intelligence and the French School: A review of an award winning project

January 25th, 2016 Posted by Energy Efficiency, Renewable-energies No Comment yet

Energy Intelligence and the French School in Cape Town (Ecole Francaise du Cap) have been working closely together over the last few years in order to improve their energy efficiency and revolutionise their approach to energy consumption and the results are proving to be impressive.

The French School consists of two campuses and is home to 485 students. The schools provide French and Cambridge English education to students from pre-primary up to grade 12 and were set up around the key principles and values of French education and scholarship.

The French School Cape Town and Energy Intelligence

Just over three years ago the French School in Hope Street, Cape Town, called upon Energy Intelligence to collaborate in investigating and implementing viable solutions to pursue a reduction in electricity consumption and make use of renewable energy. Energy Intelligence, whose mission is to help residential users, corporate clients, and asset managers improve their utility management performance, made use of their experienced team of engineers and years of experience in providing best in class utility management and energy efficiency services and products, to find the most ideal solutions to cater to the French School’s needs. By turning their electricity, water and heat usage into actionable knowledge, they were able to propose a number of viable solutions, a number of which were implemented shortly after.

Turning knowledge into plans, turning plans into action

Some of the projects implemented were the installation of a heat pump to produce hot water more efficiently than standard electric geysers, installing a 10kWp rooftop solar photovoltaic system to produce their own electricity and retrofitting a number of lights with modern LED equivalents, which are far more efficient and have longer lifespans than conventional lights. The resultant effects were soon visible, with reduced electricity consumption and resultant costs. The total effect of these projects has resulted in an overall saving of around 50%, with the Solar Photovoltaic system providing around 20% of their required energy and having produced over 20 000 kWh since its installation. In addition, the Solar Photovoltaic system produces enough electricity to feed the excess into the grid and generate additional income. These savings mean that there is a payback period of around only 5 years, making the projects extremely beneficial financially.

Visible Longterm Savings

The savings achieved to date have accumulated to over R 50 000 since the inception of the various projects and will increase at a higher and higher rate as the price of electricity increases each year.

As a result of the projects implemented by Energy Intelligence, the Cape Town French School won  the Energy Efficiency Forum Award for  the Small building Retrofit Category awarded by the City of Cape Town, in partnership with Eskom and the South African Property Owners Association, which was an extremely proud moment for both. Energy Intelligence continues to work closely with the Cape Town French School creating awareness and educating both staff and the youth and encouraging a keen interest in science, technology and engineering.

Energy Intelligence Ongoing Involvement with The French Schools

Currently the Cape Town French School’s second campus is exploring various options with Energy Intelligence to pursue the implementation of energy saving systems similar to that of the first school, and there should be more exciting projects underway in the near future!
