Sustainable Construction and Green Building — CSEC Building Technology
Sustainable construction meets present building needs while protecting the environment for the future.
What is sustainable construction?
It is building in a way that reduces environmental impact, conserves resources and energy, and creates healthy, efficient buildings. It supports sustainable development — meeting today's needs without compromising future generations.
Green building practices
- Energy efficiency — good insulation, natural ventilation and shading (important in the Caribbean climate), and energy-efficient lighting and appliances.
- Renewable energy — using solar panels and solar water heaters.
- Water conservation — rainwater harvesting and low-flow fittings.
- Sustainable materials — using renewable materials (e.g. responsibly sourced timber), recycled materials and locally produced products to cut transport.
- Waste reduction — reducing, reusing and recycling construction waste.
Benefits
- Lower running costs (less energy and water used).
- Reduced pollution and carbon footprint.
- Healthier, more comfortable buildings.
- Conservation of finite resources.
Challenges
Higher initial cost and the need for knowledge and skills in green techniques.
