Taking positive action for the future – now

ECD Architects has been a pioneer in Sustainable Design for over 40 years. Our objective is to design high quality sustainable buildings that have a positive impact on their community and their environment.

Sustainability is integrated into our designs from concept to completion, and we make sure this is reviewed at every RIBA work stage.

As part of our response to the Climate Emergency we have signed up to Architect’s Declare, the AJ RetroFirst Campaign and the RIBA 2030 Challenge.

We have created a five year plan setting out how we will change the way we work to meet these commitments.

For all of our clients, we provide an initial, free-of-charge, Passivhaus analysis at feasibility stage to enable them to make an informed choice.

Our services:

  • Integrated Passivhaus / EnerPHit Design (with or without certification)
  • Retrofit Coordination and Design
  • Passivhaus Consultancy
  • Environmental Consultancy and Sustainability Statements
  • Embodied Carbon / Lifecycle Assessments
  • Post Occupancy Evaluations and Building Performance Monitoring
  • Soft Landings services

Our team of qualified Passivhaus designers in London and Glasgow have experience designing low energy retrofits and new buildings.

Our Five Year Sustainability Plan

As signatories of both the RIBA 2030 Challenge and Architects Declare, we are committed to changing the way we work in order to meet these targets.

We have carried out a detailed review of our current knowledge, practices and tools, and assessed how these need to develop over the coming 5 years.

We have broken this down into smaller, achievable steps, allowing us to invest in the right training and software and harness knowledge from within the practice, so that all staff members are part of this change.

This process has helped us to identify business opportunities from the skills we already have and are developing, as well as find opportunities for younger members of staff to develop.

A template of our 5 year plan and an example extract forms an appendix within the Architects Declare’s Practice Guide and was presented at the launch event in November 2021.


ECD Architects have embraced the Passivhaus approach, and its factual standard based on building physics, due to its 25-year track record and proven accuracy.

ECD Architects are certified by ISO 9001 and ISO 14001 to ensure our quality and environmental working standards.
