Building Physics / Sustainability Consultant

Our Sustainable Futures team provides expert guidance on sustainable places and buildings, with over 15 years of experience across a variety of building typologies and uses. From low-rise housing to tall buildings, we've delivered projects ranging from small infill developments to large-scale regeneration and innovative modular construction. As a certified B Corp and signatories of Architects Declare, RIBA 2030, and UKGBC, we are committed to advancing sustainable design.

A fantastic opportunity exists for an intermediate Building Physics/Sustainability Consultant with an interest in housing design to join our small, friendly and busy team. This role will involve delivering expert consultancy services and contributing to the design and delivery of energy-efficient, high-performing, and sustainable housing projects. You will apply your skills in energy modelling, daylight/sunlight analysis, and overheating assessments to ensure compliance with building regulations and sustainability standards, including Part L (2021), CIBSE TM59, and the GLA's environmental requirements.

In addition, you will contribute to initiatives such as Whole Lifecycle Carbon Assessments (WLCA), Circular Economy strategies, and Net Zero Carbon evaluations, collaborating with in-house and external teams to drive innovative design solutions that prioritise energy efficiency, occupant wellbeing, and environmental stewardship.

Key Responsibilities include but are not limited to the following:

• Conducting energy modelling, daylight/sunlight analysis, overheating assessments, and thermal bridging analysis using the following software and methodologies to optimise building performance at pre-planning, planning stage and beyond:

Energy - SAP calculations in Elmhurst and SBEM/DSM calculations using IESVE.

Daylight/sunlight - MBS for Revit

Overheating analysis - Part O and CIBSE TM59/TM52 analysis using IESVE.

Thermal bridging calculations - Psi-therm.

Whole life-cycle assessments - One Click LCA.

• Providing design guidance and technical expertise during client meetings and project reviews.
• Collaborating with in-house architects and external MEP engineers, structural engineers, and other stakeholders to integrate building physics and sustainability principles into design projects.
• Ensuring compliance with building codes and standards while preparing technical reports and presentations.

To be considered for this role, the successful candidate will have:

• An MSc in Sustainable Design, Environmental Engineering, or a related field.
• 5+ years' experience in building physics and sustainability consultancy, including carrying out SAP calculations and DSM energy modelling, checking overheating risks in line with CIBSE TM59 and familiarity with the BRE's daylight/sunlight methodology.
• Relevant accreditations (e.g., BREEAM, SAP, DEA, CEEQUAL, IEMA, CIBSE).
• Demonstrable experience in managing your own projects effectively.
• Familiarity with GLA requirements for residential-led developments and experience on GLA-referable projects.
• A strong understanding of UK regulations on energy, CO emissions, daylight/sunlight access, and overheating risks.
• Knowledge of current and emerging legislation and industry best practices in sustainability and carbon management.
• Excellent project management skills, with the ability to manage your own workload and guide others effectively.
• Strong analytical skills and attention to detail, with the ability to interpret data and present informed conclusions.
• Strong written and verbal communication skills, including experience preparing reports and delivering presentations.
• A good knowledge of UK planning and construction processes.

HTA offers a supportive environment and opportunities for professional development. You will work on impactful projects that shape urban living while contributing to net-zero carbon strategies, embodied carbon assessments, and post-occupancy evaluations.
