Senior Building Physics Engineer

Overview

In this Senior role, you will deliver expert building physics and energy modelling across UK projects, shaping design strategies and improving performance. You’ll work with cross-disciplinary teams to embed low-carbon principles and robust modelling into early design decisions. You’ll apply advanced simulations to optimise fabric, daylight, ventilation, and energy strategies, contributing to net-zero ambitions. This position combines hands-on technical delivery with mentoring and knowledge sharing to grow national capability from the Plymouth hub.

Responsibilities

• Support building physics workstreams on complex projects (thermal, energy, daylight, overheating, natural ventilation, comfort analyses)
• Develop and optimise energy strategies, TM54 assessments, and low-carbon design solutions
• Advise on façade performance, passive design, solar control, and fabric optimisation
• Ensure compliance with UK regulations (Part L, TM52/TM59, EPC) and contribute to BREEAM, WELL, or LEED credits
• Produce high-quality technical reports and communicate findings to clients and design teams
• Collaborate with MEP, architecture, sustainability and digital engineering teams to integrate building physics into design solutions
• Influence early-stage design decisions (massing, orientation, glazing ratios, shading, ventilation feasibility)
• Support development and adoption of digital modelling workflows and best practices
• Mentor and share knowledge with graduates and junior engineers
• Contribute to internal knowledge sharing, technical workshops, and thought leadership

Key requirements

• Extensive experience in building physics, energy modelling, and performance analysis in a consultancy
• Advanced proficiency with IES-VE (or equivalent) including complex simulation, calibration, and QA
• Strong technical knowledge of passive design, low-carbon buildings, façade performance, and dynamic environmental behaviour
• Experience delivering multi-disciplinary projects and presenting technical information clearly to clients and teams

• Collaborative mindset
• Clear communication with clients and teams
• Mentoring and knowledge sharing
• IES-VE (or equivalent)
• Energy modelling and performance analysis
• Passive design and low-carbon building knowledge
