Hangzhou is promoting rooftop solar photovoltaic


Hangzhou Intermediate People's Court (Wikiwand 2021)


In March 2022, Hangzhou Development and Reform Commission published an announcement titled "Implementation Suggestions on Further Accelerating the Construction of Photovoltaic Power Projects in the City". This document suggested that all companies, institutions and public facilities in Hangzhou should have solar photovoltaic (PV) facilities on their rooftops. This proposal aims to improve the city's self-sufficiency in electricity and contribute to the achievement of zero carbon emissions(Hangzhou Development and Reform Commission 2022).

The proposal was not well accepted. Although some local businesses have been trying to install solar PV roofs since this announcement was released, the first one that fulfilled all its requirements was the distributed solar PV project on the roof of the Hangzhou Intermediate People's Court, completed in February 2023(Hangzhou News 2023).

There are two possible reasons local businesses have not kept pace with the public sector regarding renewable energy. First, Hangzhou's PV industry is still in the early to mid stages of development. There is still a need to increase the production of the local industry, and it does not have the sufficient practical experience to sustain the trust of other companies. Therefore, considering the possible risks, most local companies are willing to wait until the industry is more mature before joining. Second, while the government provides financial incentives for PV projects, it also requires higher quality, and subsidies are only available for installations that have been used for more than one year. This increased the costs and risks that local companies had to take. Therefore, planners should not be in a high position when trying to motivate local companies and institutions but need to communicate with stakeholders closely. Moreover, it is essential to consider the local realities when proposing measures and not expect the desired outcomes immediately.

Vanke Future Sky City-A sustainable community of the future?

图片
LEED (Leadership in Energy and Environmental Design) is a sustainable community certification system promoted by the United States Green Building Council (USGBC). The first community to be officially certified by LEED in China is the  precinct  project named Vanke Future Sky City. The design of this precinct focuses on a TOD complex with office, commercial, residential, cultural and sports functions, and its sustainability performance consists of three main aspects: l   High-density land use.  Several high-rise residential towers are erected next to the metro station to achieve more effective usage of land resources and reduce travel distances. l   Greening. Providing large areas of grassland to enhance life quality and satisfy the requirements of green, low-carbon development. l   Change in transport options. Achieving environmental sustainability by encouraging low-emission forms of transport such as metro, cycling and walking. Compared to...

About Sustainable Buildings

The first week's lecture introduced some basic concepts and the history of the development of sustainable cities. This included the concepts of green and sustainable buildings, which I was very interested in. This type of building aims to reduce energy consumption, use resources efficiently and reduce the environmental impact of artificial structures through advanced technology or design. However, achieving this requires a certain level of technology and, more importantly, adequate budgets, thus for many developing countries building sustainability seems unachievable. I, therefore, wondered how sustainability could be achieved through more detailed design if sustainable buildings could not be constructed immediately. One example from my civil engineering-related studies is the installation of double glazing in some areas, which is created by injecting inert gas between two pieces of glass to achieve thermal and acoustic separation. This allows the building to be more comfortable an...

Individual Digital Sustainability Journal for Hangzhou

Hangzhou is a city in the east of China with an important position regarding social and economic development. It is also a city with rapidly developing tourism and high-tech industries that have achieved a position at the forefront of sustainable development in China. Starting today, I am going to write my own evaluation of some of the sustainable buildings and projects that are currently in progress or have been completed in Hangzhou, based on my personal experiences during my study for the Bachelor of Civil Engineering in the city, along with information from the internet and the content of my sustainability course this term, and to create a digital sustainable development journal. At the beginning of the journal, I will give a general assessment of Hangzhou's urban sustainable development based on my current knowledge and understanding. In economic aspects, Hangzhou has a relatively balanced industrial structure, with many large internet companies such as Alibaba and Netease, as...
