    Environment-led Analysis
    Environment-led analysis is conducted in the field and by advanced computer design simulation.
    It places human comfort, productivity, well-being and health, in addition to sustainable and
    energy efficient design, behaviour and use, at the heart of place making in the built environment.

RCZM are RIBA Chartered Architects and environmental consultants with almost over 20 year’s experience in delivering and advising on sustainable architecture, the built environment, with professional international experience in all sectors and in particular education, mixed use, civic, corporate and residential. RCZM is a small agile practice with a life-long altruistic concern for Our environment. RCZM work collaboratively to inspire, to motivate, to share informative abilities to facilitate better building performance by design.

Awards; Finalist CIBSE 2018 Green Infrastructure Challenge for Putney High School, Shortlisted CIBSE 2020 Education and Learning - The Biophliic Classroom, Putney High School, GDST, RHS Chelsea Flower Show 2021 Gold Medal Winner - The Biophliic Classroom

RCZM are RIBA Chartered Architects and CIBSE registered Low Carbon Building Design practice. We are currently focused on strategic guidance for RIBA Sustainable Outcomes and Biophilic Design in Education. 

We use a bespoke bioregional field-research method to carry out environmental impact assessments and sustainable design appraisals in support of RIBA Stage 0 and 1. We use dynamic computer simulation to analyse low-carbon design performace and lifecycle cost and impact at RIBA Stage 1 through to Stage 4 for BREEAM, and as a precursor to Building Regulations Part L compliance. We provide Design and Access Statements in support of Planning Applications and provide Building Control Application production information and co-ordination. We carry out Post-Occupancy Evaluations in support of RIBA Stage 7 to inform RIBA Stage 0.


RCZM have been recognised by the Royal Horticultural Society for our unique and indepth research into the importance of green infrastructure and biophilic design to support wellbeing.   

The built environment is a complex product: we see its occupants as user's; if the built environment not used with awareness then all the sustainable features may prove to be ineffective. RCZM adopt a holistic approach that inspires, informs and supports human needs, but not in isolation from the surrounding world. 

We support value in the sustainability of natural, human and social capital through design that places human health and well-being at its heart. We believe sustainable design should consider its financial cost and environmental impact for its entire life-cycle by addressing the triple bottom line of social, economic and environmental performance. 

We engage in collaborative design through BIM and added-value customer-service through Soft Landings. We are comitted to the RIBA Sustainable Outcomes in support of the UN Sustainable Development Goals, and aim to tread lightly on the earth.

Biophilic Design - RHS 2021 Gold Medal Winner

The Benefits of Nature in Learning Environments


Our built environment is a multi-sensory experience, stimulated by people, the architectural atmosphere of light and space, the quality of indoor environments, learning and social interactions. Our creativity and productivity, arising from this experience, are dependent on good health and well-being.
RCZM are experienced in guidance on Green Infrastructure and its benefits to reduce the impact of climate change and enhancing the quality of our built environment to support health and wellbeing.
Working with the Photographer Matt Cattell, our ongoing research at the school has shown that the subtle reintroduction of nature through both physical and visual mediums, can enhance the quality of learning environments to benefit health, productivity, cognitive and emotional wellbeing.

The Biophilic Classroom Research Study

Putney High School


We live through our senses. What we see, touch, taste and smell affect our human physiologically and psychologically
Professor Derek Clements-Croome, University of Reading
The Biophilic project is part of our ‘Breathe’ campaign, which demonstrates how a few relatively simple steps, like bringing plants into the classroom, can have a significant impact on both wellbeing and the ability to learn.
Headmistress Suzie Longstaff, Putney High School
Not only have the plants measurably enriched the oxygen for staff and students, the plants have also had a significant effect on psychological wellbeing.

What we consider

in how we deliver


Sustainable Development
The built environment has a direct impact on the natural environment, the economy and human health and wellbeing. We can activity improve buildings by achieving comfort through passive design strategies and promoting a holistic approach to environmental design using a strategy with the aim of grounding the three pillars of sustainable design and the impact of their intended outcomes.
Principles of Construction
Designing to minimise waste and maintenance are integral to whole life asset management. Our principles of construction are developed in accordance with the BRE Green Guide to Specification and a simple palette of materials are proposed which reflects local vernacular materials used in the surrounding built environment. RCZM recommend using responsibe ISO 14001 sources within 35 to 50 mile radius of the site.
Our Project Eco-system
RCZM use holistic development principles to ensure all elements of design are identified and considered through out the delivery and occupancy process. RCZM design for performance and compliance with the national and local policies, regulations and standards for quality of life, accessibility, community benefits and connectivity, along side Passive design, CO2 reduction and protection of natural resources for economic viability and whole life value.
Building Performance Evaluation (BPE) is becoming progressively integrated into the full life cycle of a built projects. A less tangible yet decisive element of BPE is Post-occupancy Evaluation (POE), and its role and perceived value in this process. A qualitative review is undertaken to examine the increased prominence of the role of POE, its potential role within Building Information Modelling and Management (BIM) and the Building Energy Management System (BeMS).
Energy-use Behaviour
Behaviour in the home contributes to 50% of the energy consumption of the home. This study explored moderation of a persons energy-use and willingness to adopt sustainable energy consumption habits. The study builds on DEFRA's research that established behaviour change as necessary to achieve a sustainable society. The study proposes adapting the 'Behaviour Grid' for designers to motivate and raise a person's ability in support of willingness to undertake behaviour change.
Lifecycle Cost Analysis
BRE introduced BREEAM New Construction to align with legislation changes across the industry with a renewed focus on strengthening facilities management through lifecycle analysis.RCZM provide key indicators of asset management outcomes that anticipate capital and operational costs from RIBA Stage 1. Both this and the environmental impact of a development can be understood further at RIBA Stage 2 and 3 through the use of IES-VE building performance analysis software with the Integrated Material Profile and Costing Tool (IMPACT).
After Kyoto
The article, 'Whatever the politicians decide in Paris, industry's resolve must not falter’, written by by Clare, was first published in BD on the 3rd December 2015. Construction accounts for half of global energy and water consumption, but is also best placed to make the economic case for sound environmental practices.
