Sustainability

At Mark Fairhurst Architects (MFA), sustainability is embedded into every stage of the RIBA Plan of Work. We believe in a holistic and integrated approach that balances environmental responsibility with high-quality design. From the earliest project stages, we work with clients to develop strategic briefs that align design aspirations with sustainability targets, helping to future-proof developments, enhance performance, and reduce long-term costs.

Passive Design & Fabric-First Principles

Our design approach begins with a critical assessment of the site context, orientation, and opportunities to reuse existing buildings. Wherever possible, we follow fabric-first principles to maximise the performance of the building envelope before relying on active systems. This includes:

Maximising air-tightness
Incorporating super-insulated walls, floors, and roofs
Harnessing solar gain through controlled glazing and shading
Optimising natural ventilation strategies
Leveraging thermal mass for heat retention and regulation
Using incidental energy from occupants and equipment

We aim to reduce operational energy demands and retain embodied energy in existing structures where feasible, aligning projects with low or net-zero carbon goals.

Renewable Energy Integration

Where appropriate, we integrate renewable technologies to supplement passive strategies. Our portfolio includes:

Photovoltaic Panels (PV)
Installed on projects such as 4–8 Hafer Road and Koops Mills, PV systems generate clean electricity for heating and appliances.
Solar Thermal Systems
Used primarily for hot water and heating in individual homes, these systems are highly efficient and suited for standalone dwellings.
Heat Pumps
MFA was an early adopter of ground source heat pumps, first specified in 2005 at The Marble & Granite Centre, providing low-energy heating and cooling.
Mechanical Ventilation with Heat Recovery (MVHR)
Specified in several residential and hospitality schemes (e.g., 384–398 Commercial Road, Koops Mills, and Windmill Hill, Ruislip), MVHR systems reduce heat loss while maintaining air quality.
Other Technologies
We consider Combined Heat and Power (CHP), biomass systems, micro-wind turbines, and connections to existing or planned community energy grids.

Water & Drainage (SuDS)

We implement Sustainable Urban Drainage Systems (SuDS) that manage surface water on-site through capture, storage, filtration, and gradual release. Our toolkit includes:

Attenuation tanks
Grey water recycling
Green roofs
Permeable paving
Rainwater harvesting (e.g., water butts for planters)

These systems mimic natural hydrology, reduce runoff, and improve site resilience.

Daylight, Sunlight & Natural Ventilation

Good daylighting is central to both comfort and energy efficiency. We design buildings to maximise natural light and ventilation in all habitable rooms, minimising the need for artificial lighting and mechanical cooling. Skylights, light wells, and shading devices are integrated as architectural features. Our designs are regularly tested by the Building Research Establishment (BRE) to ensure compliance with best practice guidelines.

Transport & Sustainable Mobility

In line with the London Plan, MFA supports developments that prioritise public transport, cycling, walking, and car-sharing. We often advise clients on car-free developments, provision of cycle storage, and installation of electric vehicle charging points. Sustainable mobility is a key factor in reducing emissions and enhancing liveability.

Adaptive Reuse

Reusing and adapting existing buildings is often the most sustainable design response. At feasibility stage, we assess buildings for embodied energy, adaptability, and long-term performance with Whole Life Cycle Carbon Assessments. Our experience includes the restoration and extension of listed and historic buildings, often in conservation areas, preserving heritage while reducing environmental impact.

Modern Methods of Construction (MMC)

MFA promotes prefabrication and modular construction where appropriate to reduce waste, improve build quality, and shorten construction programmes. These methods also support the delivery of net-zero homes by ensuring airtightness and construction accuracy.

Green Infrastructure & Biodiversity

We enhance biodiversity and contribute to London’s green infrastructure by incorporating:

Green and brown roofs
Native planting schemes
Private and communal landscaping
Habitat enhancement (e.g., bat and bird boxes)
Urban greening factor (UGF) targets

Sustainability & the Circular Economy

We aim to design buildings that minimise waste and maximise lifecycle value. This includes:

Designing for adaptability and reuse
Reducing demolition and construction waste
Sourcing durable, low-impact materials
Reclaiming or recycling site resources

Sustainability at MFA is not a checklist—it’s a mindset embedded in our practice. Through collaboration with environmental consultants, engineers, and local authorities, we deliver thoughtful, responsible, and regenerative architecture that supports both people and the planet.
