What are 3 features commonly used in green buildings?
The main objective of any green building project is to minimize the environmental impact of a structure throughout its lifecycle: from siting and design, construction, operation, maintenance, renovation and demolition. To accomplish this, the green building concept combines the principles of siting and structure efficiency, energy and water efficiency, materials and indoor environmental quality optimization, operations and maintenance optimization, waste and toxics reduction and recycling or disposal strategies.
1. Reduced energy consumption
One of the most popular green building practices is reducing energy usage by optimizing siting and structures. This includes building orientation, window placement, and light fixtures to maximize daylighting and heat loss control. This can also include the use of natural ventilation, high-efficiency lighting, and energy efficient HVAC systems.
2. Air leakage controls
Another common green building feature is minimizing air leaks from windows and walls, which will reduce the energy required to cool or heat a building. Preventing air leakage also allows for heat recovery ventilation (HRV) and helps to retain the heat that naturally escapes from a building, which further reduces the demand on HVAC systems.
3. Water conservation
A green building can conserve water by using reclaimed or recycled water in the construction process. This can be accomplished through the re-use of plumbing fixtures or by implementing a system that uses rainwater to supplement water supply. Additionally, incorporating recycling or composting systems in the building reduces waste and improves indoor air quality.
