Green building trend severely undervalued in local real estate 09:27 | 15/12/2020 Green building trend severely undervalued in local real estate Besides COVID-19, the second key word of the year is âgreen buildingâ but many developers and consumers are still hazy on the concept. A âgreenâ building is deemed one that, in its design, construction, and operation, reduces or eliminates negative impacts and can create positive impacts on the climate and natural environment. Green buildings preserve precious natural resources and improve quality of life. However, in Vietnam the concept is sometimes confused with buildings covered with green trees only, sporting the usual image of a resort or an eco-urban area. Meanwhile, key features such as the efficient use of energy, water, and other resources, use of renewable energy, pollution, and waste reduction measures, and good air quality indoors are glossed over.
