Sustainability Statement — Joshua Heasman Architecture

At JHA, sustainability is at the core of our approach. It is built into our process, we consider it our duty to build solid and long lasting, low-energy homes.

We acknowledge the significant contribution of the construction industry to global carbon emissions. We confront this reality consciously and with enthusiasm, ensuring our projects creatively respond to climate change.

Our objective is to create architecturally ambitious buildings that also prioritize social and environmental responsibility. We believe these ideals go hand in hand, resulting in better buildings. As architects, we constantly push the boundaries of innovation, understanding the potential of emerging materials, technologies, and performance metrics.

Simultaneously, we recognize the enduring value of certain sustainable traditions, often shaped by generations of experience. We seek to modernize these design traditions and be respectful, sensitive, and caring neighbors to the communities and sites where we work.

With each project, we aim to uphold this commitment and build upon our ever-evolving knowledge, ambitions, and principles.

This expanded version outlines our core principles in more detail while emphasizing our commitment to sustainability.

Sustainable Approach

At JHA, our approach to sustainability revolves around four core principles, each offering a unique perspective on our commitment to eco-conscious architecture:

1. Reuse:

We recognize that one of the most impactful actions we can take, as architects and clients, is simply to build less or re-use. This does not need to translate to smaller homes, but to reduced construction footprints, and minimise demolition and waste. By starting with the question of how much we genuinely need to build and what can be preserved, we not only decrease waste and costs but also reduce disruption, transportation, and environmental impact. This philosophy leads us to prioritize renovation over demolition whenever possible and recycle on-site materials, preserving a layer of the site's history.

2. Build Better:

At JHA, we incorporate thoughtful design principles into our buildings, ensuring they have "good bones" that are well-constructed and climate-appropriate. We embrace passive design, capitalizing on the sun's warmth in winter and cool summer breezes while creating seasonally responsive facades. To ensure year-round comfort, we layer thermal mass, insulation, double glazing, and natural ventilation. We collect rainwater and maximize natural light to minimize the need for artificial lighting. We also prioritize responsibly sourced materials, using carbon-intensive materials intentionally to stabilize internal temperatures and enhance thermal comfort. Building better not only results in longer-lasting structures but also offers an exceptional living experience.

3. Build Smart:

Building smart involves harnessing emerging technologies and systems to optimize performance, particularly in terms of power, heating, and cooling. JHA is a strong advocate for all-electric buildings, discouraging the use of non-renewable fossil fuels like gas. Many of our projects are operationally carbon-neutral, relying on solar panels, battery storage, and heat pumps for a closed loop, renewable system. We also employ advanced heating and cooling systems, such as underfloor hydronics, chilled wall and ceiling panels, heat exchangers, and pellet heaters. While building smart may require upfront investment, it pays dividends in the initial use and long term running cost.

4. Live with Nature:

Respecting the natural world is central to our values at JHA. We make a conscious effort to minimise our impact on the places and landscapes we touch. This begins with site selection that preserves significant trees and minimizes land disturbances. Our designs typically integrate with landscapes, courtyards, and gardens, allowing for natural light, air, and a connection to the outdoors. This approach not only enriches the lives of our clients but also promotes good indoor air quality and climate awareness. We also prioritize natural and renewable materials to create buildings that harmonize with their surroundings.
