Our Objectives

To reduce energy waste through collaboration

We link utility suppliers, service providers, corporate donors and beneficiaries for a more equitable sharing and sustainable use of energy.

To Reduce Greenhouse Gas Emissions

Fossil Fuels contribute to the build up of Greenhouse Gasses in our atmosphere. DaysE implements projects reducing or removing fossil fuel dependence. We help large energy users to reduce energy waste and lower their environmental impact.

To Combat Fuel Poverty

Fuel Poverty is a global problem. Some users are wasting energy with insufficient resources to implement savings. Some have no access to energy for life's basic necessities. Through collaboration, DaysE aims to combat both.
Sign up for the DaysE chain. We produce a quarterly newsletter with news from our projects and our partners.

Our Services

Corporate Social Responsibility

For large energy users, we offer an innovative model of collaboration through energy, fulfilling many of your corporate social responsibility goals: Including environmental protection, employee engagement, community support, marketplace relationship building.

Behaviour Change

Our pilot programme, developed by a behaviour change expert, engages employees in implementing energy savings throughout their day to benefit their chosen cause. The results of their efforts are displayed visually and in real time.

Energy Fund Managers

Our energy experts identify energy wastage and/or alternative sources. In return we receive a contribution towards an energy fund either by direct donation of cash, services or materials, energy credits or rebates.  We use this fund to implement energy projects with non profit groups. The energy savings / reduction of fuel poverty continues in a cyclical process.

Trying to heat and light the production areas was becoming increasingly problematic, from both a cost and ergonomic perspective. Colm Byrne was exceptionally thorough in clarifying our need and putting in place a project plan to implement. We were very impressed with his professionalism, expertise and follow-up. It helped too that he is very personable. While the project did not go as smoothly as originally planned, Colm managed the challenges that emerged and ensured that the standards required were reached. The upgrade has transformed the facility. The new radiant heat panels have allowed for more timely and better heat distribution. The new LED lighting has literally ‘brightened the place up’ and created a safer and more pleasant working environment. Our investment was approximately 50% of the cost and running costs have reduced in line with expectation. We would highly recommend DAYSE.

CEO, Speedpak Group

DaysE opened my eyes to another way of giving back, not as visible as other options perhaps but effective on many levels. We have been helped to save energy, important for the environment and to save costs, essential for our business. The savings on heating in particular are significant and I also notice we are spending less on electricity.The beauty of DaysE is that we have helped others to save energy and costs too.
