Benefits of Green Buildings in Construction

Green buildings concept

     Green buildings are also known as 'sustainable buildings' or 'eco-homes', refer to a structure which is designed and constructed to conserve water, energy, material resources and are environmentally friendly and resource-efficient throughout a building's life cycle.

The main goal of the green buildings is to reduce the overall impact of pollution, environmental degradation and increase the natural environment by efficiently using natural resources, protecting human’s health and reducing waste.

Components of green buildings

     There are four main components or elements in a green building. They are water, energy, materials and health.

Water efficiency

     Reducing water consumption or minimizing the usage of water is achieved in a building by collecting rainwater or by installing greywater systems.

This method helps to recycle the collected water and use it for irrigation, toilet flushing and for other purposes like washing vehicles, cleaning verandas, etc.

Energy efficiency

      Sustainable buildings include measures to reduce energy consumption. To reduce operating energy use, the design of the building should include high-performance windows, extra insulation in walls, ceilings and floors, low energy appliances and renewable energy sources like solar panels.

Effective window installations can provide more natural light, thereby decreasing the need for electric lighting during the day. Using solar water heater panels reduces energy costs.

Electrical energy can be reduced by using led lights or by using low energy efficient appliances.

Materials used in green buildings

     Materials used in these buildings should be obtained from natural, renewable sources which are collected in a sustainable way. Selection of materials should follow the criteria that include resource availability, minimal environmental impact, embodied energy efficiency, non-toxic, potential reuse and recyclability.

Sustainably sourced wood is one of the best materials to ensure low embodied energy and minimal environmental impact.

Recycled building components are of high quality and cheaper compared to conventional materials.

Health benefits

      Using non-toxic and natural materials and products will improve the indoor air quality and reduce the sick building syndrome. These buildings are emission-free, have low volatile organic compounds and are moisture resistant.

Proper ventilation can increase the light inside the building and allow the building to breathe in the fresh air.

Why choose Green Buildings?

      Due to energy shortages, an increase in global warming, degrading human health, it makes sense to choose green buildings that are durable, saves energy, and reduces waste and pollution.

There are number of reasons to choose green buildings. Some of them are:

  •   Use of materials that are non-toxic and sustainable.
  •   Use of energy efficient and renewable energy sources.
  •   Free from all toxic gases in building surroundings.
  •   Improve occupant's health conditions.
  •   Reducing energy consumption using low energy efficient appliances.
  •   Controlling water scarcity and saving for future generations.
  •   Good indoor and outdoor atmosphere in the surroundings.

     Nowadays, most of the countries are adopting green buildings to save natural resources for future generations. A green building is not just another building; it can create hope for a better future.
