Energy strategy, building performance and sustainable engineering design.
Practical sustainability integrated into every engineering decision.
Osborn Associates delivers sustainability consultancy that goes beyond compliance. We work with clients to develop energy strategies, reduce carbon impact and improve building performance across new build and refurbishment projects.
Our sustainability services are delivered in-house alongside our MEP engineering team, which means energy strategy and building services design are coordinated from day one rather than treated as separate workstreams. This integration produces better performing buildings and more cost-effective solutions.
Energy strategy, compliance and sustainable technology.
Energy Strategy & Carbon Reduction
Whole-building energy strategy development from concept through to operation. We produce net-zero carbon calculations, energy performance analysis and lifecycle cost modelling to support informed decision-making at every project stage.
Compliance & Assessment
Full BREEAM assessment and advisory services, Part L compliance analysis, SBEM calculations and Energy Performance Certificates. We navigate the regulatory landscape to deliver compliant, high-performing buildings without unnecessary cost.
Sustainable Technologies
Design and specification of renewable energy systems and sustainable building technologies. We evaluate options against performance, cost, planning requirements and maintenance considerations to recommend the right solution for each project.
Building Physics & Thermal Modelling
Our team carries out all building physics analysis in-house using industry-standard CFD and thermal modelling software. This capability allows us to optimise building performance, validate design assumptions and support planning and building control submissions.
We model overheating risk, daylight performance, natural ventilation strategies and condensation risk to ensure buildings perform as intended in real-world conditions, including under future climate change scenarios.
Sustainability and building performance consultancy.
Sustainability consultancy across every building type.
Sustainability FAQs.
BREEAM is the world's leading sustainability assessment method for buildings. It evaluates a building's environmental performance across categories including energy, water, health, materials and management. Achieving a good BREEAM rating demonstrates a commitment to sustainability and can improve asset value.
Part L of the Building Regulations sets the requirements for the conservation of fuel and power in buildings. Compliance involves demonstrating that a building meets minimum energy efficiency standards through SBEM calculations, insulation specifications and efficient building services design. We carry out Part L compliance analysis as part of our sustainability service.
Overheating assessments (typically to CIBSE TM52 for non-domestic or TM59 for residential buildings) evaluate whether a building's design will maintain comfortable temperatures during hot weather. They are increasingly required by planning authorities and building control, particularly for residential developments and buildings with high solar gains.
Yes. We carry out net-zero carbon calculations, develop energy reduction strategies and evaluate renewable technologies to help clients achieve their carbon targets. This includes lifecycle cost modelling to demonstrate the business case for sustainable investments.
When sustainability consultancy and MEP design are delivered by the same team, energy strategy decisions are coordinated with building services design from day one. This avoids the common problem of sustainability targets being bolted on after the MEP design is fixed, which typically results in more expensive and less effective solutions.
Yes. Our building physics team carries out daylight factor analysis, sunlight hours assessment and glare modelling using industry-standard software. These assessments are often required for planning applications, particularly for residential developments and buildings adjacent to existing properties.
