The public lecture on sustainable design considerations for electrical systems in building was held via Zoom on 07th May 2022 by Eng Bandula Subasinghe


The direct use of low emission electricity in place of fossil fuels is one of the most important drivers of emission reduction of buildings. As a result, electrification of buildings, minimising energy demand growth through improvements in energy efficiency and human behavioural changes will immensely support the journey to meet Net Zero emission target. Therefore, designing of energy efficient buildings and electrification of buildings play a pivotal role in this challenging pathway to 2050.

The global energy sector in 2050 is based largely on renewables, therefore consideration to have onsite renewable power generation such as Solar and wind within building developments will help support to reduce Scope 2 carbon emission. Most of the reductions in CO2 emissions through 2030 come from technologies already on the market today. But in 2050, almost half the reductions come from technologies that are currently at the demonstration or prototype phase. Major innovation efforts must take place this decade in order to bring these new technologies to market in time which Bandula is going to talk about in this lecture.

The Speaker:

Bandula Subasinghe obtained her BScEng (Hons) in Electrical Engineering in 2003 from the University of Moratuwa Sri Lanka. Bandula is a Member of Institute of Engineers Australia (MIEAust) and dual Charted professional Engineer (CPEng) (Area of Practice: Electrical and building services) of Engineers Australia and member of Institution of Engineers Sri Lanka (MIESL). Bandula has over 17 years of experience in the building services consultancy in design, design management, project management and technical review roles across multiple geographies on educational, art and culture, healthcare, pharmaceutical, industrial, residential and commercial projects. Bandula has gained broad exposure and expertise in building services design consultancy, multidisciplinary project management and sustainable design development in Australia, USA and Sri Lanka.

Bandula is passionate to deliver emerging sustainability strategies for new and existing buildings through well-coordinated energy efficient electrical design that meets global/project objectives and focusing on sustainable outcomes, circular economy, decarbonisation and electrification. Her extensive technical skills include electrification of buildings, whole of life carbon approaches, climate resilience, energy and sustainability masterplans and building services electrical design. Bandula is managing the Arup’s global electrical skills network “All electric building Design” working group connecting key electrical services representatives from all Arup regions including USA, Canada, UK and Singapore to develop a design and client information pack on the impact to our traditional approach to design for new buildings with regards to power demand estimation, spatial planning, and the implementation of  technologies such as on-site power generation and on-site power storage.
