As of January 2015 Joseph Little is an Assistant Head of School in the Dublin School of Architecture, Dublin Institute of Technology. He is a board member of the Irish Green Building Council and Irish co-operation partner of the Fraunhofer Institute for Building Physics in relation to training and development of the WUFI suite of hygrothermal evaluation software.

He holds an MSc Architecture - Advanced Environmental and Energy Studies from the Graduate School of the Environment, at Centre for Alternative Technology in Wales, and a Bachelor of Architecture from University College Dublin.

In 2016 SDAR*, the Journal of Sustainable Design & Applied Research, published research by Arregi and Little titled "Hygrothermal Risk Evaluation for the Retrofit of a Typical Solid-walled Dwelling”. It is one part of 'Built to Last - Energy Efficiency in Pre-1945 Historic Dublin Dwellings' that will be published in 2017 by Dublin City Council (with funding from Heritage Council and Department of Arts, Heritage, Regional, Rural and Gaeltacht). Little is the lead author of ‘Assessing insulation retrofits with hygrothermal simulations – Heat and moisture transfer in insulated solid stone walls’ for Historic Environment Scotland. This work was commended in the ‘Best Research’ category of the 2016 RIAI Architecture Awards.

Joseph Little Architects won the ‘Best Residential Green Building’ awards in Ireland in 2013 and 2014: the first for Ireland’s first EnerPHit (Passivhaus Institute certified deep retrofit), the second for a deep retrofit extension of a 1929 red brick house. All innovative businesses rely on the strength and commitment of the workforce. In this regard the architectural practice and consultancy greatly from the talents of many people but especially:

  • Architect and building fabric consultant Benat Arregi (now in the Industrialised Construction team of Tecnalia in the Basque Country, Spain);
  • Architect and Certified Passivhaus Designer Ann Marie Fallon (now in Architype in the UK);
  • Services engineer and LEED AP Calina Ferraro (now in Randall Lamb in San Diego, USA); 
  • Architect and Certified Passivhaus Designer Brendan O'Connor (now running Abode Design, Dublin).

Little closed the practice on taking the position of Assistant Head of School in Jan 2015. He provides advice on hygrothermal risks for a limited number of homeowners, specifiers and manufacturers. He continues his focus on building science and performance-based design, construction and retrofit through supporting and increasing the growing range of postgraduate and post-apprenticeship programmes in Dublin School of Architecture.
