8 Key Sustainable Building Practices

In a world where climate change is knocking on our door, sustainable building practices will be a defender.

It's like getting a strong umbrella before the storm hits, smarter than rushing for cover when it's already pouring.

Let's see how simple things like saving energy, using renewable power, and cutting waste can paint a brighter picture for our future.

1. Site Selection and Planning

Choosing the right construction site can be compared to picking a good spot for a garden. Just as you'd look at sunlight and soil for plants, builders consider the environment, climate, and transport options to minimize harm.

When planning a new housing project in Dhaka, careful site selection can ensure that buildings are constructed in areas less prone to flooding, reducing the impact on both the environment and future residents.

2. Energy-Efficient Design

Designing energy-efficient buildings resembles wearing a warm, cozy sweater on a cold day.

Good insulation, efficient lighting, and smart building orientation keep buildings comfortable with less energy.

Several companies use natural light and ventilation strategies, reducing the need for artificial lighting and cooling systems, thereby saving energy and cutting costs.

3. Renewable Energy Integration

Integrating renewable energy sources is imperative for achieving net-zero or net-positive energy in buildings.

Solar panels and wind turbines help buildings produce their own electricity, reducing fossil fuel use and utility bills.

The Edge in Amsterdam, one of the greenest buildings in the world, uses solar panels to produce more electricity than it consumes.

Additionally, energy harvested from elevators and revolving doors further contributes to its renewable energy supply.

4. Sustainable Materials

Picking sustainable materials means thinking about their whole lifespan, how much carbon they use, and if they fit into a circular economy.

The Friendship Centre in Gaibandha uses locally sourced materials like handmade bricks and bamboo, reducing transportation emissions and supporting local economies.

5. Water Efficiency

Water's getting scarce worldwide, so buildings need smart ways to manage it.

Apart from using less water and recycling, new ideas like small water treatment systems and water-saving landscaping are becoming popular.

The JAAGO Foundation ’s schools use rainwater harvesting systems to collect and store rainwater for use in toilets and irrigation, significantly reducing their dependence on municipal water supplies.

6. Indoor Environmental Quality

Creating a healthy indoor environment is similar to opening windows for fresh air on a sunny day.

Natural light and good ventilation improve mood and productivity, and buildings with these features are more comfortable.

Aga Khan Academy Dhaka incorporates natural ventilation and extensive greenery, creating a healthy and conducive learning environment for students.

7. Sustainable Landscaping

The integration of sustainable landscaping complements building design by enhancing biodiversity, mitigating the urban heat island effect, and promoting ecosystem services.

Green roofs, permeable pavements, and edible landscapes are emerging as integral components of sustainable site development.

The rooftop gardens of Dhaka’s commercial buildings, such as those in the Gulshan area, not only provide insulation but also reduce the urban heat island effect and promote biodiversity.

8. Waste Reduction

Reducing waste during construction mirrors decluttering before a big move.

Builders can recycle materials and design for disassembly to keep tons of waste out of landfills.

The BRAC Learning Centre in Savar utilizes recycled materials for construction and incorporates waste management practices that significantly reduce its overall waste production.

Using sustainable building practices helps create healthier, more resilient communities.

These practices reduce our environmental impact, improve quality of life, and foster economic growth.
