Principles of


Creating comfortable environments which are delightful, stimulating and attractive, while designing to minimise energy use and improve comfort, is central to environmental passive design principles. RCZM incorporate throughout RIBA Stage 0 to 4;

Comfort, health and well being

Conscious use of space, light and air

Use of landscape to cool and moderate temperatures

Form and layout to minimise energy use and increase renewable energy opportunities

Use of thermal mass to moderate temperatures and benefit form night time cooling

Heights of building increased to optimise natural ventilation

Reuse of existing and responsibly sourced materials within a 35-50 mile radius

Palette of low maintenance and pre-fabricated materials to minimise waste and disruption

Building designed for adaptability and resilience in the future

To mitigate maintenance, waste and impact on the environment RCZM select materials on the following principles;

BRE A+ to C rated principles and products

ISO 14001 accredited manufacturing

Responsibly source within 35 to 50 mile radius of the site

With the exception of material elements such as roofs, guttering, drainage and windows, materials should have a lifespan of 100+ years. RIBA Stage 2 materials and fabrication methods should be established in accordance with the BRE Green Guide to Specification. This prelimary study, based on commerical variations, is designed to support fabric-first energy performance of the buildings, which may be for, but not limited to the following reasons;

High acoustic performance

Low to zero toxins, easy to reuse/dispose of, significant health benefits throughout life cycle

The use of thermal mass

Constructor health and wellbeing

Renewable materials that store carbon throughout usable lifespan

Robust in handling, transportation and onsite construction

In summary
Designing to minimise waste and maintenance are integral to whole life asset management. Principles of construction will be 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.
