Our mission

Symphony Energy is an engineering and technology company specialising in innovative environmental services. We partner with clients who have made sustainability a key part of their organisation’s strategy, helping them to achieve long-term value through unrivalled energy efficiency.

To achieve this, we invest heavily in our research and development to completely rethink, even reimagine how buildings use energy so you can shape a more sustainable future for your business. With our combined expertise, product ecosystem and patented technology, we offer the most cost-effective end-to-end path for optimising your building’s energy performance to meet your net zero targets.

Our story

Founded in 2011, Symphony Energy has its roots in mechanical and electrical engineering consultancy design with over 60 years combined experience in building services engineering. Over the past decade, Symphony Energy’s engineering concepts have grown in sophistication with our focus shifting from general building services to energy optimisation for buildings of any age as well as new design projects.

We have already played an instrumental role in a host of new developments and optimisations with our work nominated for several national energy sustainability awards. These have included insurer Aviva’s office building in Dublin, which was a finalist in the 2011 SEAI Energy Awards, and Boliden Tara Mines’ vast shower facility in County Meath, which was nominated for a 2016 SEAI Energy Award.

Because of our unrivalled experience, we have now developed a comprehensive roadmap for significantly reducing the energy spend and carbon footprint of any building. We have achieved this by creating a range of non-invasive, highly diversified products and services that help our clients achieve their net-zero targets, all while reducing costs.

From a boutique consultancy to an industry leader employing a team of world-class engineers and technologists, we can fulfil projects of any size and any scope.

Our goal is to help you achieve your sustainability targets through building energy optimisation.

See how we have been helping industry-leading businesses take huge strides towards reaching their net zero commitments.
