The construction industry is one of the main areas impacted by the increasing popularity of the green movement. Home building, sustainable design, green building materials and green architecture principles present exciting challenges in the area of sustainable building.
Sustainable building is also known as green building or green construction. Sustainable building involves practices and procedures that range from choosing a site to designing, building, maintaining, and renovating. These practices and procedures concern themselves with efficient energy, water, and resource use, and the reduction of waste and environmental degradation, among others.
Sustainable building aims to reduce the environmental impact of construction. Since buildings contribute to a great deal of our land use, water and resource consumption and atmospheric alteration, diminishing this influence is vital to maintaining the health of our people and planet. Sustainable building brings a wide array of materials, practices, and products to the development and design of eco-friendly construction. Such projects often promote solar and/or wind elements for the conversion and creation of energy, alternative building materials, and green building concepts to bring about the goal of low-impact construction.
Some of the central aims of sustainable building include:
- Materials efficiency (using green materials such as renewable plant materials like bamboo and straw, lumber from sustainably managed forests, and a range of non-toxic, reusable, renewable, and recyclable products.)
- Taking advantage of renewable resources (e.g. using sunlight through passive solar, active solar, and photovoltaic techniques, using plants and trees in green roofs and rain gardens, and using packed gravel or permeable concrete instead of conventional concrete or asphalt to enhance replenishment of ground water.)
- Reducing environmental impact (reducing the amount of natural resources buildings consume and the amount of pollution given off)
- Energy efficiency (reducing energy loads with solar water heating, using high-efficiency windows and insulation in walls, ceilings, and floors to increase the efficiency of the building envelope, orienting windows and walls, and placing awnings, porches and trees to increase shading in summer or solar gain in winter, and also using techniques such as effective window placement to increase natural light and reduce the need for using electric lighting during the day.)
- Operations and maintenance optimization (applying green practices such as recycling and air quality enhancement.)
While techniques and products in the green building industry are constantly being developed, the aims remain the same. That is to create buildings with an insight toward efficient design, efficient energy, efficient water and natural resources, enhancement of indoor environment quality, and toxin and waste reduction. Optimizing one or more of these standards is the essence of green building.
The aesthetics involved in sustainable building is the principle of incorporating a design that promotes harmony with the natural surroundings and resources. Some key processes in designing green construction are the utilization of green products from local suppliers, reducing loads, optimizing systems, and generating renewable energy on-site.
Sustainable building must include measures to decrease the building’s use of energy. This ranges from solar design to energy conserving window treatments and highly efficient insulation. Designers may orient windows, walls, awnings, and porches to create shade in summer and maximize solar exposure during winter months. Window and glass placement can also maximize the natural light, reducing energy use for illumination.
A building’s environmental impact is significantly reduced by the introduction of on-site renewable energy generation such as solar power, wind energy, or biomass. The most expensive item to add to any building is power generation.
Another key element in sustainable building is water conservation. This may be achieved using various means. The use of low-flow toilets and low-flow showerheads greatly reduces water consumption. In sustainable building, it is a good idea to consider replacing toilets with bidets because the elimination of toilet paper reduces sewer traffic and increases the availability of reusable water on-site.
The use of green materials is vital in sustainable building. Many green alternative building materials are available for all aspects of construction. The building market is one of the fastest growing eco-aware wholesale and retail concerns. The building industry seems to have very quickly grasped the consumer and contractor demand for sustainable construction products. Because of this, it is quite simple to procure eco-friendly construction materials for green building. There are literally thousands of green alternative products available to builders everywhere.
Through the above examples, you can easily see that sustainable building is a thorough and devoted construction process that achieves eco-friendly, low-impact, environmentally conscious results.
