BedZED – An example of sustainable urban living

Overview

The Beddington Zero Energy Development (BedZED) is a pioneering environmentally friendly housing community in Hackbridge, Southwest London. Designed to achieve zero carbon emissions, BedZED promotes urban sustainability by reducing resource consumption, managing waste effectively, creating green spaces, and offering sustainable transport solutions.

Water Consumption

BedZED’s innovative water management system has reduced water consumption to half the national average in London, a water-stressed area. Key measures include:

• Grey Water Recycling: A green water plant filters waste water from showers, washing machines, and sinks using reed beds that remove impurities such as soap and detergent. The treated water is reused for toilet flushing and garden irrigation, reducing reliance on freshwater supplies.
• Rainwater Management: Rainwater from roofs is directed into the river system via a network of pipes, bypassing storm drainage systems to save energy and reduce water treatment demands.
• Permeable Surfaces: Pathways made from permeable materials allow water to filter back into the water table, reducing urban runoff and helping prevent localised flooding.
• Water-Saving Fixtures: Homes feature aerators on taps to reduce flow, low-flow showerheads, and smaller baths, all of which contribute to significant water savings.

Energy Consumption

BedZED has reduced energy use by an impressive 90% through energy-efficient building design and renewable energy solutions:

• Insulation: Homes are built with extra-thick walls and triple-glazed windows to retain heat, significantly reducing the need for heating in winter months.
• Natural Ventilation: Buildings are designed to use natural airflow systems, avoiding the need for energy-intensive air conditioning.
• Solar Heating: South-facing sun spaces capture and store solar heat, providing natural warmth and reducing reliance on traditional heating methods.
• Low-Energy Appliances: All homes are fitted with A-rated appliances, such as fridges and washing machines, along with low-energy LED lighting, reducing overall electricity consumption.
• Solar Panels: Photovoltaic panels generate electricity for appliances, outdoor lighting, and car charging points, promoting renewable energy use.
• Biomass CHP System: A combined heat and power plant burns biomass to generate both heat and electricity, meeting additional energy needs sustainably.

Green Space

BedZED integrates green spaces to enhance biodiversity, improve the local environment, and promote residents’ well-being:

• Green Roofs: These retain rainwater for later use, such as irrigation, and provide habitats for a wide range of plants and wildlife, contributing to increased biodiversity.
• Community Gardens: Shared gardens allow residents to grow their own food, improving air quality and providing social and recreational opportunities.
• Wildlife Corridors: Landscaping encourages the movement of local wildlife, helping maintain and improve urban biodiversity.

Transport

BedZED prioritises sustainable transport strategies to reduce traffic congestion and carbon emissions:

• Public Transport Access: The site is strategically located near major public transport networks, ensuring residents can commute easily without cars.
• Car Club: A community electric car-sharing scheme provides residents with access to vehicles when needed, reducing individual car ownership and emissions.
• On-Site Workspaces: Many residents work in offices located within BedZED, significantly reducing commuting distances and traffic congestion.
• Active Travel: BedZED promotes walking and cycling by offering safe paths and secure bike storage, making these sustainable modes of travel more appealing.

Waste Management

BedZED promotes a circular economy by minimising waste and maximising recycling:

• Recycling Bins: Homes are equipped with compartmentalised bins to sort recyclable materials such as plastics, paper, and glass.
• Composting: Organic waste is composted on-site and used to fertilise community gardens, reducing landfill waste.
• Sustainable Construction: Recycled and sustainably sourced materials were used in BedZED’s construction, setting an example for reducing waste in urban development.

Conclusion

BedZED exemplifies sustainable urban living by conserving water, reducing energy consumption, managing waste, creating green spaces, and promoting sustainable transport. Its innovative design demonstrates how urban areas can reduce their environmental impact while maintaining a high standard of living for residents.
