Dr Julio Bros Williamson

Research Fellow


Dr Julio Bros-Williamson is a Research Fellow and Lecturer in climate change and its impact on building performance at Edinburgh Napier University, School of Engineering and the Built Environment, Scotland, UK. He is a firm contributor to The Scottish Energy Centre (SEC), working on the renewable, building energy efficiency and sustainability sector.
Julio graduated with a PhD from Edinburgh Napier University in 2019 with a thesis that examined the impact of climate change and longitudinal envelope performance dilapidation on dwellings in Scotland, under the direction of Prof John I Currie. He is an architect graduated from the School of Architecture at the Marista University in Mexico City and holds an MSc in Energy Efficient Building (distinction) from Oxford Brookes University. Julio obtained his professional certification in 2003 as a Chartered Architect (Mexico) accredited by the Secretaria de Educacion Publica (Spanish) allowing him to become a member of the Mexican College of Architects. In 2010 he took up the role as a Director and contributing member of the Scottish Ecological Design Association (SEDA) as well as becoming its Treasurer from 2015 to 2018 .

Since working at Napier University, Julio follows the idea of applied and research-integrated teaching engaging with professional practices and enhancing academic learning by providing real-life industry and professional experience. Most project briefs implemented in his teaching expand towards multidisciplinary collaborations developing the design of buildings and urban environments considering occupant’s wellbeing and low carbon performance, expanding towards the use of advanced fabrication techniques such as timber off-site solutions and bio-based materials. Julio has been a Lecturer and module leader in the Undergraduate Architectural Technology degree (BSc and Graduate apprentice) particularly in design studio-based learning providing workshop and tutorials (average 80 students per year) and technically based lectures focusing on sustainable design and healthy building design subjects. At postgraduate level, he initiated with other colleagues the MSc in Architectural Technology and Building Performance, the first Scottish Architectural Technology programme certified by the Chartered Institute of Architectural Technologist (CIAT) whilst also being awarded a Centre of Excellence. He has been a module leader of the Building Energy Performance subject area since 2010 and from January 2019 to August 2020 acted as interim Programme Leader, restructuring the modules by creating two new areas of learning; Integrated building retrofit and Building Information Modelling. His teaching is recognised by positive student feedback with continuous ratings between 90%-100% overall satisfaction (COGNOS Analytics, Napier), placing it at the top quarter score of modules in the School of Engineering and Built Environment.
He has extensive experience of Master’s and Undergraduate research dissertations and final MSc project supervision and is currently a supervisor of two PhDs and one MRes. Additionally, at the Edinburgh School of Architecture and Landscape Architecture (ESALA) at the University of Edinburgh, he is an invited tutor and delivers an annual postgraduate level guest lecture. Julio is also actively involved in providing Knowledge Exchange/Transfer at different levels; as an academic supervisor of two KTP’s (Innovate UK) and graduate employability schemes (Napier beX).

As a means of dissemination of project results and outcomes, he has published five peer-review journal papers and ten conference papers as well as industrial research outputs on topics relating to building performance, retrofit methods and results of funded research/ consultancy. Equally, Julio has experience in journal reviewing (Elsevier) and has had the opportunity to review and lead on conference organising (plenary sessions). He has been Co-Chair at two International Association for Housing Science (IAHS) World Congress on Housing conferences, as well as Chair & part of the scientific committee at the 2nd IBPSA uSIM2020 conference. He was a scientific reviewer at the PLEA 2017 Conference “Design to Thrive” and since 2018 a scientific committee member of the CIBSE Symposium.

As a researcher, his portfolio extends into both new build and refurbishment of buildings including the implementation of sustainable and energy efficient methods to existing housing stock. He has an excellent track-record of securing research funding as well as experience in leading successful research bids. Julio has demonstrated potential, aspiration and commitment to deliver sustained high-quality research by collaborating in national and internationally funded projects concerning the sustainability of the built environment, building performance of buildings (POE’s and BPE’s) and measurement of indoor air quality in buildings. Since joining Napier University he has collaborated as PI and Co-PI in over 50 private and publicly funded projects amounting to more than £700K in University revenue. He has been actively involved in assisting and providing expert knowledge to collaborative projects while being part of Scotland’s 2020 Built Environment sub-group from 2011 to 2016, which created Retrofit Scotland. Julio is currently PI for three industry/ Scottish Government funded projects and CoPI for a large Scottish Government and CSIC project involved as project manager and work package leader working collaboratively with industry and other academics. These projects highlights Julio’s ability to manage a research team by providing guidance and mentorship to early career researchers, students involved and other colleagues.

Julio is passionate about the implementation, optimisation and use of IT software and hardware, he possess digital skills using point cloud scanners (FARO) to capture interior and exterior space into a .gbxml digital format transferrable to BIM. Julio is a trained and certified Commercial Operations Pilot (drones) after undertaking a competency assessment programme. He has extensive skills in the use of dynamic thermal modelling using IES-VE to deliver simulations of building designs. Within the teaching and learning strategies, he is proficient on the use of module management tools (Moodle), lecture recording (Panopto) and distance learning methods for theory and studio-based modules.
