Brevity’s sustainability podcast series ‘Stories of Sustainability’ features interviews with guests who are some of the most inspiring sustainability leaders in their respective field. Each episode is full of insights, inspiration and tips to motivate everyone to create small changes.

This blog captures the essence of Laura’s interview with Patrick Osborne, head of sustainability at ECE Architecture. He is a certified European Passivhaus designer with a wealth of experience in low-energy building projects. Patrick discusses the pressing need for a fabric-first approach, Passivhaus design, and challenges in creating sustainable buildings.

The path to sustainable design

Patrick’s journey into sustainability is an inspiration. From his traditional architectural background to his immersion in the sustainable design realm, his unique experience has transformed the way he approaches building projects. By incorporating his knowledge from the Centre for Alternative Technology, he champions sustainability in his role at ECE Architects.

Simplicity is key

In the world of architecture, the challenge lies in maintaining the aesthetic appeal and functionality of buildings while integrating sustainable principles. Patrick’s wisdom: “simplify. Overcomplicated designs often hinder a building’s ability to function efficiently. Architects must consider how their designs align with the needs of occupants.”

The quest for sustainable materials

Discovering innovative, sustainable materials or building techniques is a critical aspect of creating greener buildings. Patrick emphasises the importance of insulation, offsite construction, and timber framing. These strategies reduce embodied carbon and enhance energy efficiency.

Minimising waste during construction

Construction sites contribute significantly to landfills, with 13% of materials never being used. Patrick highlights the need to rethink the building industry’s approach, urging architects and contractors to address waste at its source. Offsite construction and reusing existing materials play vital roles in reducing waste.

The built environment is responsible for a staggering 45% of the UK’s carbon emissions

Architects must incorporate renewable energy sources, such as solar and wind power, into their designs. While the UK government has debated the inclusion of solar panels as a standard in new builds, it remains a key consideration for a more sustainable future.

The challenge of cost

Cost is a common challenge when implementing sustainable design practices. Tight budgets often lead to compromises in quality and sustainability. Architects must educate clients on the long-term benefits of sustainable designs to make the upfront costs more palatable.

Favourite regeneration projects

Regeneration projects that take old, neglected buildings and transform them into efficient, sustainable structures hold a special place in Patrick’s heart. One standout project is the retrofitting of a 1930s telephone exchange building, now called Entopia, in Cambridge achieving Passivhaus standards while preserving the building’s historical charm.

Tips for a more sustainable built environment

Patrick offers practical tips for our listeners to make their built environments more sustainable. These tips include reducing hot water temperatures, considering air source heat pumps, insulating homes effectively, and seeking recognised standards of energy efficiency. Furthermore, exploring sustainable projects and learning from real-life examples can provide valuable insights.

Patrick’s insights are a beacon of hope in the quest for sustainability in the built environment. From simplifying designs to embracing innovative materials, there are numerous ways to make a difference. The challenges are real, but so are the opportunities to create a better, greener future.
