Seoul's Bold Step Toward a Sustainable Future: Mandatory Regenerative Heat Systems for New Buildings
In a groundbreaking move to combat climate change, the Seoul Metropolitan Government has announced that from next year, all new non-residential buildings over 30,000 square meters will be required to install regenerative heat systems. This initiative, introduced at the Climate Accompanying Mayor's Meeting and C40 Steering Committee in Paris, is part of Seoul's ambitious project to slash greenhouse gas emissions from buildings.
Non-residential buildings, while comprising a mere 2.4% of all structures in Seoul, are responsible for approximately 30% of emissions in the sector. To address this disproportionate impact, the new policy mandates the installation of renewable energy systems, including hydrothermal and waste heat, for all qualifying new constructions. The city's green building design standards will be updated to require that at least 50% of the underground development area, or equivalent energy needs, be met through these sustainable sources.
However, this progressive step comes with challenges. The Korea Institute of Construction Industry estimates that construction costs could increase by 30-40% due to the integration of renewable energy systems. To mitigate this financial burden, the Seoul government will subsidize some construction costs and ease the floor area ratio by up to 15%, facilitating more flexible and spacious building designs.
In urban Seoul, where space is at a premium, achieving Zero Energy Building (ZEB) standards through on-site renewable installations can be difficult. The city plans to enhance its regulations to support off-site renewable energy setups, ensuring that even densely populated areas can contribute to sustainability goals. Additionally, there is a push to include air heat pumps in the renewable energy category, which would align with international practices and further bolster energy efficiency efforts.
The head of Seoul's Climate and Environment Division emphasized the urgency of these measures, citing increasing public concern over extreme weather events like heat waves and heavy rains. By developing a localized energy model that enhances energy independence, Seoul aims to set a precedent in urban sustainability and climate action.
Starting next year, the Seoul Metropolitan Government will require new non-residential buildings of 30,000 square meters or more to install regenerative heat systems. This initiative, part of the city's broader carbon reduction project, was announced at an international meeting in Paris. The aim is to reduce greenhouse gas emissions, with non-residential buildings accounting for a significant portion despite being a small fraction of total buildings. The new standards include installing renewable energy systems like hydrothermal and waste heat. However, there are concerns about increased construction costs, estimated to rise by 30-40%. To alleviate this, the city plans to provide financial support and relax floor area ratio regulations. The government also aims to address limitations in urban areas by allowing off-site renewable energy installations and promoting air heat pumps, potentially revising laws to classify air heat as a renewable energy source.
FAQs Section
1. What is regenerative heat, and why is it important? Regenerative heat refers to systems that recycle heat energy, often wasted in traditional systems, to improve efficiency. It's important for reducing energy consumption and greenhouse gas emissions.
2. Why are non-residential buildings targeted first? Non-residential buildings, though only 2.4% of all buildings in Seoul, account for about 30% of greenhouse gas emissions in the building sector. Targeting these buildings offers a significant opportunity to reduce emissions.
3. What are the expected construction cost increases? The construction costs for non-residential buildings incorporating renewable energy systems are expected to rise by 30-40%.
4. How will the Seoul Metropolitan Government support building owners? The government plans to ease the financial burden by providing partial funding for renewable heat systems and easing the floor area ratio regulations, which allows for more flexible building designs.
5. What is the significance of off-site renewable energy installations? Due to space constraints in urban areas, on-site installations can be challenging. Off-site installations allow buildings to contribute to renewable energy goals without physical space limitations.
