📍 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.
What you’ll be doing
Carrying out dynamic simulation and thermal modelling using software like IES or DesignBuilder
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
What they’re looking for
A hands-on technical background in sustainability, building services, or environmental engineering
Proven experience in energy modelling tools (e.g., IES VE, DesignBuilder, 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
Why it’s worth a conversation
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
