Global trends attest to the fact that the popularity of the green building is on the rise. While this fact has also been statistically proved, it is the core benefit of good health and productivity which keeps drawing contractors to the concept of a green building. In fact so predominant is this trend that today technological advances in the field of building construction is now centred around this concept of building a green building which includes:
- Maximisation of the renewable energy use,
- Minimisation of carbon footprint,
- Reduction in water usage,
- Lower emission of greenhouse gasses,
- Conservation of natural resource etc.
The below given 6 technologies associated with construction also aim to remain true to saving the Earth by utilising the concept of green building and its beneficial components.
Use of sustainable construction materials:
Building construction generally involves the consumption of a variety of raw materials in huge volumes. Integration of sustainable biodegradable and recyclable materials and their utilisation in building construction can make a huge difference, economically and otherwise. In fact the use of green construction materials provides an alternative for putting additional pressure on the already exhaustively depleted natural resources.
Most inhabitants of buildings are used to artificial lights, air-conditioners, humidifiers, room heaters etc., much more than they are to natural light and ventilation. But this results in both excessive use of energy and increased emission of greenhouse gasses, both of which adversely affect the planet. But by tweaking the architectural design of a building, it is possible to take advantage of natural light and air flowing into the building. Incorporating cross-ventilation into the design further helps translate the airflow principles into a breathable technology of building design.
It has been statistically noted that buildings use up about 13.6% of the global supply of potable water. Today advancement of technology has enabled the reduction of this water usage by:
Management of storm water:
- Installing and using fixtures which enable water conservation,
- Intelligent management of water consumption,
- Harvesting of rainwater,
- Reusing grey water after proper recycling and
- Facilitating removal of contaminants from wastewater by developing a system of on-site treatment of sewage.
Floods and erosions are quite common in the rural areas while the urban areas generally get affected by sudden heavy downpour of rains and snow. But when areas are landscaped and properly channelled, management of huge volumes of water especially in times of storms and hurricanes can be easily managed. One of the best forms of storm water management is planting trees the roots of which help to reduce the speed of water and also prevent soil erosion. Additionally these plants also help to improve the quality of air by reducing the carbon-di-oxide content and increasing the amount of oxygen in it.
Smart glass and windows:
In order to effectively deal with certain natural elements like sunlight, wind etc., traditional materials have been upgraded into smart materials. These materials like low-emittance windows , not only help to serve the conventional function of the same, they also help to significantly bring down the utility bills. Smart glass is another technology which is in the process of being developed. This smart glass is actually able to control the quantity of light that it will reflect by using a slight electrical charge. Hence they tint during peak sunlight and become transparent in its absence.
As the name suggests these roofs help to keep the rooms cool by reflecting most of the sunlight and sun’s heat that it receives. They are generally made of special tiles coated with reflective paints which help to increase their thermal emittance and solar reflectance thereby working together to enable lesser absorption of heat.
Thus going green results in a lot of advantages both financially and health-wise; but it might seem relatively costlier. However, this is only the initial cost which gets mitigated in the long run.
