Sustainability Consultant

Sustainability Consultant – Bristol Area

Location : Bristol Area

Building Services Consultancy

Hands-on | Technical | Modelling-focused

I’m currently working with a long-established building services consultancy in the Bristol area that’s looking to grow its sustainability offering. They’ve built a strong reputation delivering complex MEP projects across sectors like commercial, healthcare, education, and defence — and are now looking to bring in a hands-on Sustainability Consultant to lead technical modelling and support low‑carbon design delivery.

This role is ideal for someone with a solid technical base in energy and carbon modelling who also enjoys rolling up their sleeves and getting stuck into real projects, both in design and on‑site.

• Carrying out dynamic simulation and thermal modelling using software like IES or Design Builder
• Developing and implementing carbon reduction strategies across M&E and architectural interfaces
• Supporting with compliance reporting including EPCs, Part L, TM54, BREEAM, etc.
• Advising on low‑carbon technologies – heat pumps, CHP, PV, district energy and more
• Working closely with the M&E team to feed sustainability strategies into coordinated design
• Contributing to BIM and Revit‑based workflows for environmental analysis
• Occasionally getting on site to support commissioning, surveys, and performance reviews
• Presenting modelling results clearly to both technical and non‑technical stakeholders

• A hands‑on technical background in sustainability, building services, or environmental engineering
• Proven experience in energy modelling tools (e.g., IES VE, Design Builder, TAS, Excel‑based calcs)
• Working knowledge of UK sustainability regulations and frameworks
• Comfortable communicating across disciplines – M&E, architects, clients, and contractors
• Ideally someone who enjoys a mix of office‑based analysis and occasional site visits
• BIM / Revit experience or interest in developing those skills
• Professional accreditation (LCEA, CIBSE Low Carbon Consultant etc.) would be a plus

• You’ll be joining a consultancy where sustainability isn’t just a checkbox – it’s a core focus
• You’ll work directly with experienced engineers on projects that aim for low and zero‑carbon outcomes
• The team is pragmatic, technical, and genuinely values hands‑on problem solvers
• Hybrid working is supported, but they want someone who enjoys being engaged and involved in projects in a tangible way
