ASHRAE DL: Designing Zero Carbon Buildings – Embodied and Operational Emissions in Achieving True Zero

July 10 @ 6:00 pm - 7:00 pm

The lecture introduces a structured approach to designing zero carbon buildings, taking into account embodied and operational emissions. The way we design zero carbon buildings starts with making design decisions about the site, geometry, thermal insulation, solar gain, solar shading, thermal mass, ventilation and integration of daylight with electrical lighting. By integrating all these aspects and by balancing the need for heating and cooling, we achieve thermal comfort for building occupants. We then put all of this into number-crunching simulation and optimisation tools, which enable us to harmonise design parameters and squeeze every ‘gram’ of performance. As a result, we obtain renewable energy requirements that balance carbon emissions arising from the combination of design parameters and requirements for heating and cooling. Thus, zero emissions are achieved, and the problem is solved. What more could be there to talk about? Except there is an elephant in the room. If we don’t take embodied emissions into account, we can overshoot the time when zero emissions are expected to be achieved by three to four decades.  For that reason, embodied and operational emissions are combined into a Zero Equation to assess the requirements for achieving zero cumulative emissions by a specified year. A working example of a building is introduced, where construction materials, HVAC equipment and renewable energy systems are analysed in detail for embodied emissions. The effects of carbon storage in biomaterials and uncertainties of available data are discussed. The lecture introduces a workflow that enables designers to achieve zero carbon buildings with certainty and by a specified year.

Recommended audience:

ASHRAE members, students, architects, property developers, building stakeholders, policy makers, etc.

About the Lecturer

Prof Ljubomir Jankovic, MSc, PhD, CEng, MCIBSE, MASHRAE, FIAP, FIBPSA, has spent the past 35 years as an academic, researcher and practitioner, focusing on how environmental design of buildings can be improved using instrumental performance monitoring, dynamic simulation, advanced computer modelling methods, and utilisation of bio-sourced materials. He holds an MSc from the University of Belgrade and a PhD from the University of Birmingham, both in Mechanical Engineering. He is a Chartered Engineer, a Member of ASHRAE, a Member of CIBSE, a Fellow of the Institution of Analysts and Programmers and a Fellow of the International Building Performance Simulation Association. His professional society activities included roles of President of ASHRAE UK London and South East Chapter, Vice-President of ASHRAE UK Chapter, and an ASHRAE Distinguished Lecturer 2024-2026.
