Shanghai Grand Harmony is located in Meilong Town, Minhang District, Shanghai, at a location east of Meifu Road, west of Meijiang Road, south of Chunshen Road and north of Xingmei Road. The project commenced construction in December 2022 and received the qualified opinion of Shanghai's ultra-low energy consumption building project assessment in December 2023. The scope of the project's ultra-low-energy building covers from residential Building 1# to Building 14#, comprising a total of 14 individual buildings with 889 households and a floor area of 99,444.13 square metres. Compared with the existing energy-saving buildings, it is expected that the construction of this project as an ultra-low-energy building can reduce carbon emissions by 1,614.78 tonnes per year, which is conducive to Shanghai's goal of achieving a "carbon peak" by 2025.
The project is guided by Shanghai's climate for the design of ultra-low-energy-consumption building programmes, based on the meteorological conditions and living habits of the Shanghai area. It draws on the passive measures of local traditional buildings for the adaptive design of the building plan layout, orientation, lighting and ventilation, and the indoor space layout. Following the principle of "Passive Priority, Active Optimisation", with the indoor environment and energy consumption indicators as constraint targets, adopting the performance-based design methodology to rationally determine the technical strategies, giving priority to the use of passive measures such as external sun-shading, energy-saving doors and windows, and envelope insulation to reduce the demand for building heating and air conditioning, and combining the enhancements in equipment energy efficiency and the use of renewable energies to achieve a signifiscant reduction in the building energy consumption.
Annual heat energy consumption, annual cooling energy consumption, annual primary energy consumption for heating and air-conditioning, lighting, domestic hot water and lifts
Adhering to the principle of “Passive Priority and Active Optimization”, the ultra-low-energy building programme system is formulated, and the energy consumption indicators are calculated by the software from the "Application of Standardised Supporting Tools for Ultra-Low-Energy Buildings" project
Bedroom, living room window-to-floor area ratio: passive priority principle to optimise the window-to-floor area ratio in room
Ratio of ventilation openings to room floor area in bedrooms and living rooms: passive priority principle to optimise room ventilation openings
Exterior windows and balcony glass doors: heat-insulating profile triple-pane, double-cavity, low-emissivity hollow windows (filled with argon gas)
Exterior sun-shading: For windows without balconies (including convex windows) facing east, south and west, centre-mounted louvres are installed; for windows with balconies, the balcony structure provides self-shading
Door: Energy-saving exterior door
Thermal bridgeless design: thermal bridgeless design is implemented for the projecting structures of the external wall, including nodes of the parapet wall, balcony nodes, equipment platform nodes, convex window nodes, nodes of the curtain wall pre-embedded parts, etc.
Number of air changes N50: Adopt external doors and windows with a high airtightness level (airtightness level 8 for external windows, airtightness level 7 for balcony sliding doors, airtightness level 7 for household doors), and conduct effective airtightness treatment when various pipelines penetrate the airtight layer and external wall, such as carrying out effective airtightness treatment for nodes of pipe holes through the wall and nodes of pipelines exiting the roof
Heating and air-conditioning systems: multi-unit air-conditioning (heat pump) units
Fresh air system: High-efficiency heat recovery fresh air unit with bypass function
Lighting: High-efficiency LED lighting fixtures
Lifts: Energy-saving lifts with VVVF (Variable Voltage Variable Frequency) with energy feedback

Predictive analyses of energy efficiency can effectively reduce carbon emissions from buildings and provide strong support for achieving carbon peak by 2030. Ultra-low-energy buildings can save more than 50% of energy compared to current energy-saving buildings. If all new buildings in the future are constructed in accordance with the ultra-low energy building standard, then it is possible to save approximately 40% of the end-use energy consumption of society, significantly alleviating energy constraints. The reduction in energy consumption will inevitably lead to a reduction in greenhouse gas emissions.
