Senior Building Physicist

Due to the continuing success and growth of our AESG team, a fantastic opportunity has opened up at our award-winning Specialist Consultancy, Engineering and Advisory Firm. We are headquartered in London, Riyadh, Singapore and Dubai, Cape Town, Cairo & Sydney working throughout the Middle East, Europe and Asia. Our areas of expertise are represented in four core verticals: Building Engineering, Planning and Infrastructure, Strategy and Advisory and Commissioning, Handover and Asset Management. We pride ourselves in being leaders in the industry in each of the services that we offer. We have one of the largest dedicated team with decades of cumulative experience in sustainable design, fire and life safety, cost management, façade engineering, commissioning, building performance, waste management, environmental consultancy, carbon management and acoustics. JOB PURPOSE The Senior Building Physicist will lead and deliver advanced building performance and urban physics assessments across building and master planning projects. The role covers daylight and glare, thermal comfort, microclimate and wind comfort, solar radiation, energy performance, building envelope optimisation, passive design, climate resilience and decarbonisation. The role will translate simulation results into practical, design-led recommendations and optimisation strategies; establish robust modelling methodologies and workflows; ensure technical quality and consistency of deliverables; and support multidisciplinary project delivery and client engagement. QUALIFICATION / EXPERIENCE Bachelor’s or master’s degree in building physics, Architectural Engineering, Mechanical , Civil Engineering, Building Services Engineering, or a related discipline. Minimum 4–7 years of relevant professional experience in building physics, building performance simulation, environmental design, energy modelling, microclimate analysis, or sustainability consulting, preferably within multidisciplinary design or engineering consultancy. Proven practical experience with building performance and environmental simulation tools, supported by strong knowledge of relevant international and regional standards, codes and sustainability frameworks. Experience in energy auditing and operational building performance analysis is desirable, including the ability to interpret measured data and identify energy conservation and optimisation opportunities. Advanced proficiency in environmental analysis tools such as IES, Rhino/Grasshopper, Ladybug/Honeybee, ClimateStudio, ENVI met and/or CFD platforms. Demonstrated experience delivering daylight, glare, thermal comfort, solar radiation, wind/microclimate and building envelope optimisation studies for buildings and/or masterplans. Experience working with architects, landscape architects, MEP engineers and sustainability teams to influence design decisions through performance-based analysis. Professional accreditation such as LEED AP, WELL AP, Estidama PQP, CIBSE, ASHRAE or equivalent is advantageous. SKILLS / EXPERTISE REQUIRED Building performance simulation: advanced understanding of heat transfer, solar gains, internal loads, HVAC interactions, thermal comfort and whole-building energy performance. Daylight and glare analysis: ability to undertake and interpret daylight availability, daylight autonomy, glare and visual comfort assessments and translate results into façade and space-planning recommendations. Microclimate and urban physics: strong capability in solar radiation, outdoor thermal comfort, pedestrian wind comfort, shading and climate-responsive masterplanning assessments. Building envelope and passive design: expertise in façade performance, glazing selection, shading optimisation, orientation, massing, natural ventilation and other passive design strategies. Modelling tools and workflows: strong hands-on capability with IES-VE; strong hands-on knowledge of Rhino/Grasshopper, Ladybug/Honeybee and ClimateStudio; experience with CFD tools such as OpenFOAM or equivalent. Ability to develop parametric and comparative modelling workflows is highly desirable. Energy and decarbonisation: ability to develop energy conservation measures, compare design options, assess renewable energy opportunities and support operational energy and decarbonisation strategies. Standards and compliance: strong working knowledge of ASHRAE and CIBSE guidance and relevant regional codes; familiarity with LEED, WELL, BREEAM, Estidama/PBRS, Mostadam/PCRS and Saudi
