Feature 9. Water efficiency technologies
There are several water efficient technologies used, which are all part of sustainable construction technologies. Essentially, the technologies encompass re-use and application of efficient water supply systems. Examples include the use of dual plumbing, greywater re-use, rainwater harvesting and water conservation fixtures. These methods ensure that water is adequately managed, recycled and used for non-portable purposes like washing cars and flushing toilets. Dual plumbing, for instance, decreases
sewer traffic and enhances the potential of re-using water on-site. On the other hand, rainwater harvesting provides water for multi-purpose usage and might also be stored for future use. In general, the water efficiency sustainable construction technologies lower water usage costs and help in water conservation. In urban areas, the technologies intend to lower water wastage by 15% to address freshwater shortages.
10. Sustainable indoor environment technologies
The health and safety of the building occupants are fundamental and must be guaranteed during the construction of any building or home. As such, sustainable indoor technologies are mandatory for green construction. The materials used have to ensure green safety standards which include hazardous free elements, non- toxic materials, low volatile emissions, and moisture resistance.
For instance, materials from cork, wood
and bamboo are naturally sourced and do not have any toxic, irritating or carcinogenic elements. The use of materials with low VOCs also enhances IAQ and limits exposure to health-threatening chemicals such as vinyl, phenol-formaldehyde and lead.
11. Self-powered buildings
The advancement of constructing self- powered buildings is an art of sustainable construction technology. The reason is based on the fact that self-powered buildings bring about the realization of zero-energy construction. The buildings are built such that they are able to generate sufficient power to support their own energy needs and even direct surplus energy back into the power grid. In most cases, wind power technology is used and it is highly common in skyscrapers whereby wind turbines are mounted at the rooftops. The constant and heavy air currents at higher altitudes propel the turbine blades which generates the power requirements for the building.
12. Rammed Earth Brick
Rammed earth brick is an ancient construction technology which has lately been re-introduced to cater for the demands of environmental sustainability. The technique uses sustainably sourced raw materials. Due to technological advancements, the process of building a rammed-earth structure has been made easier but it still follows the ancient preparation process. Moist earth mixture and hard substances
like gravel or clay are mixed with stabilizing elements such as concrete and compacted to create dense, hard walls. The sourcing and formation process of rammed-earth bricks makes it ideal for sustainable construction as it lessens environmental impacts and the material can equally stabilize the temperature of a building. Rammed-earth structures contribute to fewer emissions and ensure the buildings remain cool in the summer and warm in the winter. Thoughtfully created design and
construction leave a legacy for future generations to enjoy. We have a responsibility to recognise that what we build today should endure and enhance the lives of those who come after us. The future development path at Teraciel Group is focused on the requirements of conscious and sustainable development by ensuring, inter alia, effective environmental policies and regulations, the application of best available technology, the development and support of strong environmental institutions both externally and internally, and advocacy campaigns for behavioural change. Great design and construction shouldn’t come at an environmental cost, but rather work in a sustainable relationship with the environment and make minimal impact. At Teraciel Group, our profitability is calculated based on the achievements of our triple bottom line objectives and Teraciel Engineering and Contracting (TEC) is a flag- bearer for our endeavour to be a leader in providing sustainable construction methods and sustainable, high-quality buildings.
