Climate change and the excess volume of greenhouse gases are hot global issues. While these challenges often appear to be concerns for corporations and governments to tackle, the truth is that we all play a role in shaping the world’s climate. Our daily lives, and the performance of our homes and buildings, significantly impact the environment, often in ways we might not realise. The construction industry, through embodied carbon and operational carbon of buildings, contributes over one third of global emissions. As such, it is imperative that we consider sustainability in our designs and practices.
Sustainable design in Guernsey
When designing for the future in Guernsey with sustainability and carbon responsibilities in mind, there are several factors for clients and designers to consider. While each project is unique, the underlying principles of sustainable design remain constant. Early design decisions can profoundly affect a building’s future operation, performance, adaptability to social, economic, and climate changes, and eventual disassembly.
New builds
For new constructions, utilising the site’s potential and location to maximise comfort and performance through passive solar design is crucial. Here are some key considerations:
• Passive solar design: Maximising the use of natural sunlight for heating and lighting.
• Green roofs and living walls: Enhancing insulation and biodiversity.
• Renewable energy: Incorporating solar panels or other renewable energy sources.
• High-performance insulation and fenestration: Using materials that provide excellent thermal insulation.
• Energy-efficient lighting and appliances: Implementing smart home technologies to optimise energy use.
• Sustainable building materials: Choosing materials with low environmental impact.
• Water-efficient appliances and sanitary ware: Reducing water consumption.
• Internal air quality: Ensuring airtightness and sufficient ventilation to maintain healthy indoor air.
Budget-friendly green solutions
When considering your property, cost is often a significant factor. However, there are budget-friendly ways to enhance your quality of living while still being green. Guernsey Electricity recommends a ‘Fabric First’ design approach, which involves improving the performance of the existing building fabric before upgrading heating systems. This method is versatile, covering all budgets:
• Low budget: Thermal curtains to regulate temperature.
• Medium budget: Double glazing to minimise heat loss through windows and doors.
• High budget: Upgrading insulation, possibly with an external wall insulation system.
These upgrades can lower your heating costs before considering sustainable energy sources, enhancing your home’s thermal performance effectively.
Recent planning exemptions
The recent update to the Planning Exemptions in Guernsey demonstrates a shift towards making green design options more accessible for homeowners. New exemptions include:
• Installation of solar products
• Installation of an air source heat pump
• Installation of an external insulated render system
• Installation of electric vehicle charging points
• Installation of energy storage equipment
For the complete list of exemptions and the necessary considerations for ensuring their exempt status, visit the States of Guernsey website.
Designing for a green future is a shared responsibility that involves every individual. By considering sustainable practices and design principles, we can collectively make a significant impact on our environment.
At JG Architecture, we are committed to helping you navigate these considerations, ensuring that your building projects are both sustainable and future-proof.
