The nZEB101 Project 

Research into near zero energy buildings

Researching How our Homes of the Future Will Perform

Building on an established monitoring project of low-energy dwellings which has been running for over two years, the vision for nZEB101 is to uncover the key nZEB design and operations lessons as Ireland embarks on the unprecedented mass market implementation of these low-energy buildings.

The project is supported by the Sustainable Energy Authority of Ireland and builds on an established and effective multidisciplinary collaboration of academia and experienced low-energy dwelling professionals with a history of implementing low-energy/nZEB. 

nZEB101 monitors over 101 geographically dispersed domestic and nondomestic, new and retrofit properties and ensures a statistically robust sample size which will yield: Operational performance of A rated buildings, including energy and Indoor Environmental Quality (IEQ) and “In use factors” for a span of energy-efficiency technologies including fabric elements and heat pumps.

A communications strategy is designed for widespread multimedia dissemination to a comprehensive range of target stakeholders.

The project places particular emphasis on social housing considering it is proposed that up to 45% of the dwellings constructed in Ireland over the next 10 years will be for social housing purposes, with first reports of IEQ and annual operational performance against the BER predictions scheduled in Q1.; nZEB101, due to its ambitions and multi-stranded approach ensures significant value for money for the investment made.

Our People

Dr. Oliver Kinnane

Oliver is an avid researcher and educator, an architect and engineer, and is passionate about using building science to improve the performance of our building stock. Due to is wide range of interests and varied education, including a Ph.D. in physiological modelling, a Masters of Architecture and a Bachelor of Engineering, his approach to research is multidisciplinary. By optimising building skins, systems and methods which envelop and condition our homes, and analysing our living environment and it's impact, his research focus is on the interface between the human and the building.

Dr. Shane Colclough

As a chartered engineer with an MBA and a PhD in low-energy buildings, Shane has led research into low-energy dwellings for the past 10 years at Ulster University and later at the University College of Dublin, in parallel of being principal at the consultancy firm Energy Expertise Ltd. Author of many papers on low-energy, passive house, nZEB and energy storage, he is also active in the not for profit sector and is vice-Chairman of the Passive House Association of Ireland and founding co-Chairman of nZEB Ireland. His role in nZEB101 is in the area of Post Occupancy Evaluation, looking at whether our nZEB buildings perform as expected with respect to temperature, air quality, energy consumption, and most importantly occupants requirements and requirements.

Dr. Richard O'Hegarty

Richard has an impressive background of energy analysis, structural mechanics and material science, mixed with a BE-hons degree in civil engineering from University College Dublin, an MSc in structural and environmental engineering from Trinity College Dublin and a PhD in a combined field of façade engineering and solar thermal energy from the School of Civil Engineering at TCD. These give Richard more than is needed to pursue this field of research. He has extensive industry experience and most recently completed a postdoctoral researcher position in UCD on the development of lightweight prefabricated cladding solutions for building retrofit. Caring about housing the planet’s population, Richard is focusing on assessing the in-use performance of energy efficient technologies via the nZEB101 project.

Mr. Donal Lennon

Donal has a long history with UCD, having held a number of positions most recently as the manager of the Earth Institute BEL Lab. Donal is responsible for installing monitoring equipment to measure the energy and indoor air quality of the nZEBdwellings, spanning not only the UCD campus, but also nationwide.
