Comprehensive Deep Building Retrofit

The Catherine McCauley Special School project involved a complete deep retrofit of an existing building, which presented a unique set of challenges due to its age, architectural style, and specific retrofit requirements.

The project encompassed extensive upgrades to the building’s fabric, including enhanced insulation for both walls and roofs, installation of energy-efficient doors and windows, improvements to air tightness, and the integration of LED lighting. Heating systems were also upgraded, alongside the implementation of renewable energy technologies to significantly reduce the school’s carbon footprint.

A thorough assessment was conducted to ensure that the measures undertaken would provide lasting value to the school while aligning with the objectives of the national retrofit programme. This evaluation process included a detailed analysis of energy consumption patterns and potential cost savings.

To meet the school’s heating and domestic hot water needs, school installed a cascade of three air source heat pumps, which operate in tandem with gas boilers to maintain efficiency even in sub-zero outdoor temperatures. Domestic hot water is supplied by a dedicated heat pump that uses R290, a refrigerant with a zero global warming potential (GWP), ensuring an environmentally friendly approach to heating.

The entire system is continuously monitored and optimised through an online platform, supported by a dedicated technical support team from MasterTherm Ireland. This proactive monitoring allows for timely adjustments and ensures peak performance. Additionally, MasterTherm Ireland provides annual maintenance directly, guaranteeing that the system remains in optimal condition and continues to deliver energy efficiency and reliability for the school community.

Ennis Community College

Scope of Work: Our involvement in the Ennis Community College project included a comprehensive upgrade aimed at enhancing the college’s functionality, sustainability, and overall environment for students and staff.

• Installation of External Wall Insulation: This critical step not only improves the energy efficiency of the building but also contributes to a more comfortable indoor climate.
• Replacement of Windows and Doors: Upgrading to modern, energy-efficient windows and doors has significantly enhanced the thermal performance of the college, reducing heat loss and improving overall insulation.
• Full Mechanical and Electrical Upgrade: Our project incorporated the installation of 240kW of Monoblock ASHPs (BA60i Heat Pumps) along with Photovoltaic (PV) panels. This dual approach ensures sustainable energy production and efficient heating throughout the campus.
• Extensive Internal Upgrade: The internal refurbishment has not only improved the aesthetics of the college but also enhanced its utility, creating a more inviting and functional space for learning.

The MasterTherm design team played an integral role in the detailed design of the full system, alongside providing technical support during the installation phase. Consistent with our commitment to quality, MasterTherm Ireland has fully commissioned the heat pump system, ensuring optimal performance and efficient operation. Each MasterTherm heat pump is commissioned by our meticulously trained technicians, who are dedicated to delivering the highest standards of service.

Furthermore, the entire system is monitored and optimised online, allowing for real-time performance tracking and adjustments to maximise efficiency. This proactive approach not only ensures the system operates at peak efficiency but also provides peace of mind for the college administration.
