EPC Projects

Energy Performance Contracts are mutually beneficial agreements between Green Energy Solutions and the client whereby GES make a number of energy efficient/renewable upgrades to the buildings mechanics and electrics and split the energy savings between the two on a monthly/bi-monthly basis for a set number of months/years. After this period, any energy savings made belong completely to the client. 

Green Energy Solutions are working closely with Dublin City Council after winning Ireland's first publicly tendered Energy Performance Contract. GES were also honored in Berlin at the European Energy Award for our positive work in relation to energy efficiency and sustainability and in particular this project. 


Dublin City Council

Green Energy Solutions recently entered into an Energy Performance Contract (EPC) with Dublin City Council across three leisure centre sites where by DCC would share the benefits of reduced heating and electricity bills, with the investment in new plant and maintenance by Green Energy Solutions.  This was achieved with a mix of measures, including installing of new CHP plant, Boilers, Pumps, Heat Recovery AC systems, lighting upgrades, Building Management Systems, AHU Modifications,  retro-commissioning,  and pool plant upgrades across the three facilities

This project is still ongoing, however, it was originally anticipated that it would result in 30% annual energy savings for each leisure centre, resulting in combined energy cost savings of €170,000 per annum and maintenance savings of over €70,000 per annum. However, just one year in, it looks that annual savings are higher than anticipated at 45%. This is a fantastic result that Green Energy Solutions are more than happy with as it shows energy costs overall being almost halved. 


The Watershed, Kilkenny

Following an initial energy survey, The Watersheds energy consumption was in the region of €350,000. The facility as a public building which meant carbon reduction targets of 33% by 2020. GES performed a more detailed site audit, implemented monitoring and developed a detailed opportunities list for energy savings. This list was developed into an Energy Performance Contract as GES acting as the ESCo. Annual energy savings in the region of €75,000 were eventually achieved.

Areas targeted were the training pitches flood lighting, greater controls on indoor lighting, PIR controls in back areas, heat recovery on AHUs, pump upgrades to more efficient IE rating and inverters installed, reduced flow rates, reduced base load following night time analysis. Maintenance savings were also made with switching of suppliers and seeking outside expertise. Micro CHP unit was installed and a bore hole utilised for water supply. Dermot Gaynor, the centre manager, has requested GES to survey the centre again in late 2017/early 2018 to develop further opportuniites.
