Sustainability
A commitment to sustainability is shared by everyone at AHR
Find out how our Retrofit Toolkit can help youWe design with lasting impact in mind – creating spaces that are healthy, efficient and inspiring. Our designs are driven by low-energy strategies and a deep understanding of how people use space. Through every project and decision, we aim to leave the world better than we found it.
Led by our sustainability group and supported by champions across each of our offices, our architects, building surveyors, interior and landscape designers work together to deliver inventive, practical solutions. We actively reduce both embodied and operational carbon, with a strong focus on retrofit, reuse and repurposing to unlock the environmental value of existing buildings.
Our expertise in net zero design and Passivhaus principles supports the delivery of high-performance, resilient buildings. Whether we’re designing new developments or improving the performance of existing assets, we bring together innovation, technical knowledge and a commitment to long-term sustainability.
We believe sustainability and social value go hand in hand. People’s health, wellbeing and prosperity are intrinsically linked to the quality of the spaces they live, work and learn in. That’s why we incorporate biophilic design, accessibility, and long-term adaptability into our thinking – creating places that support both environmental goals and community needs.
Carbon reduction plan
Actively reducing our carbon footprint
As signatories to the RIBA 2030 Climate Challenge and Architects Declare, we’re taking clear, accountable steps towards a low carbon future. Our Carbon Reduction Plan, now in its fourth year, sets out how we’ll reach carbon neutrality by 2030 across our operations and declared Scope 3 activities. We track progress annually against targets aligned with RIBA, RICS and the wider built environment, keeping us ahead of the 2050 goal set by the Climate Change Act.

Sustainability Approach
At AHR, we focus on creating spaces that enhance the lives and wellbeing of people, and I am proud to champion this.
The way we live is evolving and at AHR we work to shape environments that support this. Sustainability is evident not only in my working practice but also in my everyday life. As a mentor to many, I thrive on making a difference, sharing my knowledge and enthusiasm - not only within the practice - but at conferences and also contributing to technical papers.”

Achieving Net Zero Carbon
Backed by robust strategies, we are driving a future where buildings play a restorative, regenerative, and self-sustaining role. Our approach focuses on reducing energy consumption, reusing existing environments, re-greening urban areas and promoting sustainable travel.
In the UK, 80% of buildings contributing to the 2050 Net Zero Carbon target already exist, many facing risks of becoming stranded or toxic assets. Through a practical, design-led approach, we deliver net zero carbon outcomes across new-build and refurbishment projects. Our data-driven Zero Carbon Today Methodology and Retrofit Toolkit provide structured, achievable pathways to reduce operational energy and embodied carbon, helping you review assets strategically to lower costs and reduce carbon.
A collective effort
We believe delivering sustainable places calls for collaboration that embraces transparency, drives innovation, and creates lasting positive impact. We invest in new technologies, materials, and tools, and create space for open dialogue with communities and colleagues to strengthen our approach.
Through initiatives like our Decarbonisation Roundtable series, we bring together voices from across the built environment to share insight, challenge thinking and support progress. We monitor and measure the impact of every project, using what we learn to inform future decisions. By supporting the RIBA 2030 Climate Challenge and Architects Declare, we align our efforts with a shared ambition to accelerate meaningful change across the industry.
Recognised accreditations
As specialists in delivering healthy, sustainable buildings, we have expertise across recognised accreditation standards including BREEAM, LEED, WELL, NABERS, BRE and DEC. We work closely with clients to apply these appropriately, whether full certification is required or principles alone.
As Passivhaus Trust members, we are proud to have delivered award-winning Passivhaus projects, including the world’s largest Passivhaus education building, and have in-house Passivhaus certified designers across all our UK offices. This expertise feeds into the technical design of all our projects – regardless of aspirations for formal certification.
