Description
Step into a senior role where your building physics expertise directly shapes low-energy, low-carbon buildings from concept to operation. This is a chance to lead technically challenging projects, influence design decisions, and drive best practice in performance-led design within a collaborative, forward-thinking team.
About the Role:
As Senior Building Physics Engineer, you will lead advanced building performance analysis across a range of complex projects, from early-stage feasibility through to detailed design and post-occupancy evaluation. You will be the go-to specialist for energy, thermal comfort and carbon modelling, guiding design teams and clients towards compliant, efficient and resilient solutions. Your work will underpin planning, certification and whole-life carbon strategies, ensuring robust, evidence-based outcomes.
Key Responsibilities:
* Lead advanced building energy modelling using tools such as IES-VE and/or EnergyPlus across multiple projects.
* Develop, run and interpret dynamic thermal and overheating assessments in line with Part O and TM54 methodologies.
* Produce compliance calculations, reports and evidence for Part L and related UK Building Regulations.
* Undertake whole life carbon assessments using platforms such as One Click LCA, informing design optimisation and carbon reduction strategies.
* Manage and deliver BREEAM assessments, coordinating inputs from design teams and preparing high-quality submissions.
* Provide clear technical guidance to architects, engineers and clients, presenting complex analysis in a concise, non-technical manner.
* Lead performance-led design reviews, challenging and refining design proposals based on modelling insights.
* Mentor junior team members in building physics methods, tools and best practice, supporting their technical development.
Key Requirements:
* Significant experience in building physics or building performance engineering, ideally in a consultancy environment.
* Advanced proficiency in dynamic building energy modelling using IES-VE and/or EnergyPlus on complex, multi-discipline projects.
* Proven track record delivering Part L compliance and detailed thermal/overheating assessments in line with UK guidance (including TM54).
* Strong understanding of UK Building Regulations, CIBSE guidance and current industry standards for energy, comfort and ventilation.
* Demonstrable experience preparing clear, technical reports and presenting modelling outcomes to design teams and clients.
* Ability to manage multiple projects, prioritise workloads and deliver to agreed deadlines with minimal supervision.
* Strong stakeholder coordination skills, working closely with architects, MEP engineers and sustainability specialists.
Desirable Skills:
* Experience leading or supporting BREEAM assessments, including evidence collation and submission.
* Practical experience using One Click LCA or similar tools for whole life carbon and embodied carbon analysis.
* Familiarity with other certification frameworks (e.g. LEED, WELL, NABERS) and performance rating schemes.
* Experience with parametric analysis workflows and/or scripting to streamline modelling processes.
* Knowledge of post-occupancy evaluation, in-use performance verification and closing the performance gap.
Qualifications:
* Degree in Building Services Engineering, Mechanical Engineering, Architectural Engineering, Physics, Sustainability or a closely related discipline.
* Postgraduate qualification in building physics, energy systems, sustainability or similar (preferred).
* Chartered or working towards Chartered status with CIBSE, IMechE or equivalent professional body (preferred).
* Certified BREEAM Assessor status or a clear path towards accreditation (desirable).
