This project is located in Ningbo, China, positioned as a large-scale high-end residential community with a total construction area of 50,000 square meters, covering multiple high-rise residential buildings, supporting commercial spaces and leisure green areas. There are more than 500 households in total, with a large span of unit types, ranging from about 90 square meters for the smallest unit to 1,000 square meters for the largest one. To adapt to the spatial characteristics and living needs of different unit types, the project adopts an independent system design for each household, ensuring that the HVAC system of each household can operate independently and be adjusted autonomously. Ningbo has a subtropical monsoon climate, with hot and humid summers (maximum temperature up to 38℃) and cold and damp winters (minimum temperature down to -5℃). Residents have high requirements for the comfort, energy efficiency, intelligence and functionality of the HVAC system. As a key high-end residential project in Ningbo, this project aims to create a comfortable, energy-saving and convenient living environment for residents, while highlighting the high-quality positioning of the community.
