Energy & Sustainability
Decarbonisation pathways, performance optimisation and compliance support across the built environment.
Energy and Sustainability Assessments
Reducing energy consumption, carbon emissions, and increasing the sustainability of buildings is now both a natural and legal driver for many organisations. Whether the building is a singular residential home or a large, complex commercial or industrial factory, the core principles of energy and sustainability assessments remain the exact same.
Unfortunately, many CSR managers and building clients fall foul of budget-sheet requirements for projects that may appear green on paper but provide no real sustainable outcome. These projects are often subject to intense criticism when residents or building owners find that systems are underperforming and energy or carbon emission reductions do not match the capital investment.
This is where true sustainability assessments and reports play a vital role—treating each individual building on its own merits and providing a specialist understanding of building physics, system integration, and complex environmental systems to deliver cooling, heating, and energy generation through projects that actually make a difference and provide a favourable return on investment.
My Protocols
Baseline and Performance Auditing
Establishing a clear baseline of current building occupant behaviour, actual energy consumption, utility data, and historic building construction to understand how the asset currently performs in real-world conditions.
Building Physics and Integrated Design
Applying building physics and integrated engineering solutions to match the building's natural advantageous gains, orientation, fabric performance, and system applications, ensuring engineered systems work in harmony with the structure.
Behavioural Science and System Controls
Addressing the human element through behavioural science, change management, and detailed optimisation of controls and building management systems (BMS) to eliminate operational waste and align occupant habits with building design.
My Services
Sustainability Assessments
Site-based inspection to carry out a full assessment of operational energy use. This includes identifying energy waste, human interface issues, options for reducing losses, capturing advantageous gains, and assessing the viability of Low and Zero Carbon (LZC) technologies.
Sustainable Design
RIBA Stage 4 fully coordinated mechanical, electrical, and public health systems designed using intelligent, integrated thinking. This enables the building physics and engineered systems to work together, ensuring native performance benefits are fully exploited while addressing thermal losses and operational inefficiencies.
Behavioural Change
Addressing human interaction, particularly across large estates and multi-user buildings where heating, cooling, and lighting controls frequently conflict. Rooted in behavioural science principles, this service focuses on the underlying reasons behind user habits, social norms, and establishing sustainable operational practices. David holds a background in behavioural sciences alongside a postgraduate qualification in Sustainable Buildings from De Montfort University.
Renewable Energy & LZC Technologies
Application of renewable energy and low or zero carbon technologies in strict accordance with the Energy Hierarchy. LZC systems are specified only after energy losses have been minimised and efficiency maximised to ensure a clear, viable return on investment. This approach avoids greenwashing and eco-bling—costly, highly visible additions that fail to deliver real environmental value and often increase whole-life embodied carbon.
Post Occupancy Evaluation (POE)
Ongoing performance assessments conducted over a 12 to 24 month period following handover. This process establishes a structured feedback loop to fine-tune both building plant controls and occupant habits, ensuring projected carbon and energy savings are fully realised in practice.
