Journal 11: Sustainability city – Singapore

 



Singapore is one of the most densely populated cities in the world, with a population of less than 500 square kilometers and a population of over 5 million.In the last century, when government managers were committed to building Singapore into a world tourist city, Singapore has become a world-famous green city with decades of development.

The first is urban water. Two-thirds of Singapore's land area is a catchment, where water is stored in 17 reservoirs, including the coastal basin at the heart of the city. In addition, urban wastewater can be collected and treated to produce enough water to drink, which can meet 30 percent of a city's water needs.To some extent, this enables the urban water supply system to be recycled without excessive waste of water resources.

On the other hand, the Singapore government plans to build a new "smart" city -- Tengah for the city. In order to ensure that the community can provide residents with a comfortable living environment in the hot Southeast Asian climate under the premise of Green City, the designers try to reimagine the air conditioning.Cold water, which will be cooled using solar energy, will be channelled through the area's houses, meaning residents will not need to install inefficient outdoor AC condensers.
In addition, the planners used computer modeling to simulate airflow and heat capture throughout the community, so that human activities and buildings make urban areas significantly more comfortable than the surrounding natural environment. Elsewhere, "smart" lights will be turned off when public Spaces are left empty, rubbish will be stored centrally, and monitors will detect when it needs to be collected.

In general, Singapore has been leading the way in sustainable urban development, and has gradually become a model for cities around the world to learn from.

Journal 8: Madreselva Building / Vicca Verde

Image
  The Madreselva Building in Peru is a low-cost sustainable ecological Building designed by Vicca Verde in 2014. The building is located in the heart of the city, which is often lacking in greenery in modern cities, and this was one of the issues to be considered at the beginning of the project. The project takes into account the efficient use of materials and resources, and the local wood is specially treated to meet the requirements of being built as a tall building. In addition, it is environmentally friendly from the beginning of construction to the end of its life. This is helped by the use of recyclable materials that have a low environmental impact. Moreover, the rainwater collection system of the building can be used to irrigate the green plants around the building and realize the internal circulation system of the building. As a result, the design not only enhances the quality of life of the building, but also enables it to function well in low cost maintenance conditions. In

Journal 13 : Geothermal heat pump

Image
 The Geothermal heat pump system, and efficient renewable energy technology, has been widely accepted in residential and commercial buildings. Geothermal heat pumps are used for space heating and cooling and water heating. The advantage of ground source heat pumps is that they concentrate heat that occurs naturally, rather than generating heat by burning fossil fuels. Geothermal heat pumps can be used to provide domestic hot water when the system is running. Many residential systems are now equipped with thermostats, which transfer excess heat from the compressor of a geothermal heat pump to the house's hot water tank. When the local heat pump system is not working, the desuperheater does not provide hot water in spring and autumn. But because geothermal heat pumps are so much more efficient than other forms of hot water, manufacturers are starting to offer "full demand" systems, which use a single heat exchanger to meet all a home's hot water needs. These facilities

        Image: Kamuthi Solar Project, source from: Greencitytimes India was the first country in the world to establish an official government agency for non-traditional energy, the Indian Ministry of New and Renewable Energy. India has been trying to find more sustainable sources of energy since the 1980s. The mission of the Ministry of New and Renewable Energy is to "increase the share of clean energy, increase its availability, improve its accessibility, increase energy affordability and maximize energy equity", with India aiming to provide solar power to more than 60 million Indian homes by 2022. The Kamuthi Solar Project is a solar photovoltaic (PV) farm capable of providing 648 megawatts of power. It is located in the town of Kamuthi, Ramanathapuram, India. It has more than 2.5 million individual Solar PV modules on 2,500 acres. The Kamuthi solar project provides energy to about 300,000 homes. Moreover, the project cost $710 million and became operational in 2016. Grow
