AN APPROACH FOR NET ZERO EMISSION
Net zero energy cities are defined as the city where the total carbon-dioxide emission is balanced by its elimination, from the environment. Most countries across the world aim to reduce the emission and achieve net zero. As per the net zero cities, annually over 75% of co2 emissions are discharged from urban areas. Globally over 240 cities have targeted to achieve net zero or carbon neutrality by 2050 . Many, get inspired by the campaigns like Race to Zero initiated by the United Nations. According to reports presented by World Economic Forum more than 1000 cities have participated in Race to Zero initiative(United Nations, 2021). However, out of one thousand only 240 cities are successful in setting the target for net zero. This is because, despite public concern, raised pollution, and global warming, the government is still struggling to arrange funds and investors, as the net zero concept is too expensive in practice. The ideology of the net zero approach is to explore the different strategies, including policies, design frameworks, and natural ways to reduce carbon dioxide emissions to achieve net zero.
As per the net zero Newcastle 2030 action plans, several goals are set down. Yet, the concept of sustainable farming has taken no notice. Urban farming in Seol, Korea is one the best example of carbon reduction from urban farming. It not only reduces the co2 but also urban heating. Another example is underground farming in Clapham, which uses 100% renewable energy for its 6500 sq.m farm. Despite many good practices, urban farming is not taken under consideration for big-scale projects.
This blog aims to understand the urban context and design a district with an emphasis on Urban Farming to achieve a net zero energy district. The overall aim of this discussion has the following objectives:
- For advanced green innovation, making the city a truly sustainable ecosystem.
- Create a complete, innovative, sustainable, and economic ecosystem with the green schema.
- Expand innovation assets for future business investors.
Examples: the Innovation Hubs, Singapore, labs in the city center (Helix Plus) connected by sustainable transport.
- Via a sustainable design approach, solve the city’s problems.
- Attract the attention of local and international business investors.
- A good standard of form, orientation, passive design, building fabric, and green infrastructure to reduce energy demand.
- Creating an ideal model for easy adaption throughout the UK.
- A substantial level of sustainability is demonstrated by the applicant’s adoption of the latest technologies in the project. Which include site management, site water usage, site transport, waste recycling and reuse, and environmentally friendly materials and construction methods.
- A decrease in overall CO2 equivalent emissions.
- Use a hierarchy to optimize the use of local renewable or low-carbon energy. prioritizing decentralized energy programs, then additional renewable energy options, and finally additional lower-carbon energy solutions. Where no decentralized energy scheme exists, strategic and other large-scale developments must assess the feasibility of providing such an infrastructure and, if feasible, implement such schemes.
Discussion and Conclusion
As Newcastle City has an industrial background, before world war I, the major occupation in the UK is agriculture and farming. During world war II, the industrial era started which convert the majority of fertile land into an industrial zone. This led to heavy land/soil contamination. After 100 years, these industries are still operating, and are responsible for huge carbon-dioxide production annually. The vacant land is highly contaminated, which requires strategies like crop rotation and crop irrigation to become healthy land. Many cities have already the progress to becoming net zero emission cities, however none of their strategies talks about the sustainable natural approach for overcoming this issue. As many cities want to be NZEC but due to the lack of funding and investors failed to achieve this goal. As a designer, before choosing the technology, we should plan the form and orientation of the building in a way that requires less energy to operate.
