Junior 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 a Junior Building Physics/Sustainability Consultant with an interest in housing design to join our small, friendly and busy team, helping drive the sustainability agenda in housing design. Working within an interdisciplinary environment, you will support the delivery of energy-efficient and sustainable housing projects, collaborating with some of the most aspirational developers in the sector. From early-stage design through to post-occupancy evaluation, this role offers career growth, thought leadership opportunities, and the chance to make a meaningful impact.

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.

• Assist in collaborating with the in-house architecture team as well as external MEP engineers, structural engineers and other stakeholders to integrate building physics and sustainability principles into design projects.
• Perform simulations and assessments to ensure compliance with building codes and standards and contribute to providing technical support to the architecture team.
• Assist in preparing technical reports and presentations for clients and project teams.
• Collaborating with in-house and external teams, providing design input throughout project stages.
• Contributing to Whole Lifecycle Carbon Assessments (WLCA) and Circular Economy (CE) studies for GLA-compliant residential-led projects.
• Researching sustainable solutions, ensuring regulatory compliance, and delivering data-driven insights.
• Involvement in Net-zero carbon strategies and assessments (both operational and embodied) and post-occupancy evaluations.

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

• An MSc in Sustainable Design, Environmental Engineering, or other relevant field.
• 1-2 years+ relevant experience in the building physics and sustainability sector, including energy, overheating and daylight/sunlight analysis, in addition to WLCA and CE assessments.
• Familiarity with GLA requirements for energy/CO reductions, overheating, WLCA, and CE assessments.
• Strong analytical, organisational, and communication skills, with attention to detail and the ability to manage workloads independently.
• Knowledge of UK building regulations and methodologies such as RICS for WLCA.
• Motivation to develop your career and contribute to sustainable design innovation.

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