Project Case | Shanghai Qingpu Ultra-Low Energy Consumption Demonstration Project: Practicing the Ultra-Low Energy Consumption Concept and Leading the Green and Low-Carbon Transformation

For many years, Shanghai has adhered to a strategy of adapting measures to local conditions and adopting differentiated policies to promote green development in the construction sector. District governments, based on regional resource endowments, have achieved many pioneering experiences in aspects such as energy saving and carbon reduction in new buildings, improvement of energy efficiency in existing buildings, and transformation and upgrading of the construction industry. To this end, we are launching the "Carbon Pioneer" series, focusing on promoting the experience and highlights of various districts in green building development, energy efficiency renovation of existing buildings, green ecological urban construction, and intelligent construction, and further inspiring district industry management departments to find solutions to difficulties and bottlenecks in their work. This issue will introduce the characteristics, highlights, and experience of Qingpu District's ultra-low energy consumption demonstration project. Let's take a look ↓

Project Overview

Located in the core area of Qingpu District, the 18-01 and 21-01 plots on the south side of Zhuying Road in Yingpu Street, Qingpu District, have a total construction area of 121,300 square meters. Together with the surrounding 17-01, 19-01, 22-01, 23-02, and 24-01 plots, they constitute Qingpu District's ultra-low energy consumption concentrated demonstration area. The project is adjacent to Maohejing River to the south and Dongdayinggang plot to the east. Within a 1-kilometer radius are Qingpu Ring City Water System Park and Changdao Park, with abundant surrounding landscape resources and a beautiful environment.

Project Highlights

1. Actively applying the ultra-low energy consumption concept to promote the green and low-carbon transformation of buildings.

2. Following the principles of sustainable development, using moderately advanced design methods to provide users with updatable indoor soft and hard space environments.

3. Adhering to a people-oriented philosophy, providing suitable spatial environments for residential activities.

4. All equipment uses energy-efficient models and is equipped with certain self-control components to achieve maximum energy saving.

Technical Measures

1. Adopting passive measures such as external shading, energy-efficient windows, and thermal insulation of the enclosure structure to reduce the building's heating and air conditioning needs, and combining equipment energy efficiency improvements and renewable energy utilization to achieve a significant reduction in building energy consumption.

2. The roof insulation material uses extruded polystyrene foam board (XPS), with a dry density of 35 (Kg/m³), a thermal conductivity of 0.03W/(㎡·K), a heat storage coefficient of 0.32W/(㎡·K), a correction coefficient of 1.10, and a calculated thickness of 104mm. The waterproof layer of the project roof structure is located below the insulation layer, which is an inverted roof. According to the industry standard "Technical Regulations for Inverted Roofs", the insulation layer thickness needs to be increased by 25% based on the calculated value. The roof insulation material uses 130mm extruded polystyrene foam board (XPS).

3. The integrated insulation exterior wall system uses an 80mm thick Tai Luo You double-sided composite sandwich insulation exterior wall system. The cast-in-place exterior wall uses a silicon graphene demouldable insulation template integrated system.

4. The sandwich insulation exterior wall system is connected using stainless steel truss connectors, and the silicon graphene demouldable insulation template integrated wall system is anchored using thermal break stainless steel connectors.

5. Large-scale implementation of solar photovoltaic power generation on the main building roof, with a total installed capacity of 2241 photovoltaic modules, with an annual power generation of approximately 1.06 million kWh.

Construction Measures

1. Maximizing resource saving and reducing construction activities with negative environmental impacts, achieving "four reductions and one environmental protection," namely energy saving, land saving, water saving, material saving, and environmental protection, reducing explicit and implicit carbon emissions.

2. Bulk materials such as premixed concrete, premixed mortar, aerated concrete blocks, and rolls are all products with green building material certification, promoting the green and low-carbon transformation of the building materials industry.
