A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:

NUIG fosters more energy efficiency attitudes, behaviours and practices in its staff, students and visitors through numerous measures, brief illustration follows:
1) Battle of the buildings, more here http://www.nuigalway.ie/sustainability/projectsresources/battleofthebuildings/
2) Green Flag initiative, more here http://www.nuigalway.ie/sustainability/projectsresources/the-green-flag-award/
3) Sustainable Energy Community, more here http://www.nuigalway.ie/sustainability/projectsresources/sustainableenergycommunitiessec/
4) Green Labs impacts behaviour, practice and technology adoption, more here http://www.nuigalway.ie/sustainability/projectsresources/thegreenlabsinitiative/
5) The Engineering building at NUI Galway, which was opened in July 2011, consolidates education and research activities in the various engineering disciplines into one building, which not only provides a learning environment, but itself acts as a teaching and learning tool. It is serving as a ‘living laboratory’ for engineering, where live data sets from numerous types of sensors are being used to illustrate structural engineering and building performance concepts in undergraduate teaching and in the development of full-scale research in structural engineering and energy. The building contains green-building initiatives, which will provide working models for students. Several of the building’s constructional elements have consciously been left exposed, as visual learning tools.
6) At strategic points on campus energy and water use reminders illustrating current, past and low usage help shape the thought and attitudes of staff, students and visitors to reduce their energy and water use on campus and beyond.


A brief description of energy use standards and controls employed by the institution:

ISO 50001 Operation standards:

NUI Galway achieved ISO 50001 status in 2012. This means that NUI Galway is operating an internationally recognised Energy Management System Standard within the university.

ISO 50001 is an international standard that enables organisations to establish the systems and processes necessary to improve energy performance, including energy efficiency, use and consumption.


A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:

Retrofit of LEDs and energy efficient lighting through out the campus. A recent fit out in 2020 has seen 5,000 LEDs installed on campus.


A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

Passive solar heating has been embedded in buildings for many years now. The engineering building in this link was commissioned in 2012 http://www.nuigalway.ie/new-engineering-building/ . The large 14,250 sq m building has passive heating with natural and built shading devices, please view link for more.

Another building - Aras de Brun finished in 2020 underwent a deep retrofit and achieves a performance improvement of 42% in electrical and 91% in thermal energy related usage. A heat pump with 50kW solar PV and battery storage is currently being optimised.


A brief description of co-generation employed by the institution:

Combined Heat and Power (CHP) is installed on campus in the larger buildings of the Arts and Science Concourse, the James Hardiman Library and the Alice Perry Engineering Building. 3 CHP units of 300kW, 350kW and 150kW are utilised on campus.


A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:

In 2019 and across campus energy performance reductions from 462 to 237 kWh/sq.m, or 49%, have been achieved since 2006. These figures account for both electricity and thermal energy use, and are predominantly due to high efficiency technology installation, for more see https://www.nuigalway.ie/media/sustainability/files/Energy-Review-Report--October-2020.pdf

Technology improvements have impacted across our schools and disciplines and as an example our laboratories are the first in Europe to achieve green labs status see here https://www.mygreenlab.org . A range of high efficiency technologies together with energy and resource conservation measures have helped establish our green labs.

A district heating plan ahas been designed and is currently being costed after which tendering and commissioning will follow.
