In terms of green construction: the structures and materials demolished from old buildings were piled up on site, taking up a significant amount of space, and there are dust problems and health and safety issues. Solution: Cooperate with construction waste recycling companies, and optimize construction schedule to minimize the time that building space is occupied by on-sites wastes.
In terms of energy system operation: the lighting control area is too large, resulting in energy waste when only a few people are present after work. Solution: Designate certain areas as "overtime zones" for building users off work. Implement property inspection and management during off-hours.
Building users opinion
The indoor temperature is maintained in the range of 20~24 degrees throughout the year, ensuring a comfortable environment for people. There is no phenomenon of "overheating in winter and overcooling in summer" in typical office buildings due to the "over-design" of air conditioning system. All spaces are free of draft, with even temperature distribution.
After the project was completed, air quality testing was carried out, and all indicators met the most stringent international standards. The indoor air is fresh and clean. There is no feeling of suffocation in a closed meeting room for a long time.
All workstation areas in the project make full use of daylighting. In case of insufficient daylight, individual artificial lighting fixtures can also automatically adjust the brightness to provide comfortable desktop illumination and relieve visual fatigue.
The project is located on the east side of the Shanghai Outer Ring Road, approximately 50m away. The Outer Ring Road experiences heavy traffic, resulting in significant background traffic noise at the project site.

Furthermore, this project aims to establish work coffee bars, gyms, ergonomic home furnishings, and employee sleeping cabins in public areas to create a "humanistic" office environment that integrates work and rest for users.
By establishing a "healthy, comfortable, and humane" office environment, the productivity of users can be effectively enhanced while mitigating physical discomfort caused by external weather conditions and thermal discomfort. Additionally, it can alleviate mental stress induced by noise pollution and surrounding light disturbances during work.
The office environment, which prioritizes the health, comfort, and well-being of employees, has a positive impact on their physical and mental health, work efficiency, business performance, and collaboration. Although difficult to quantify precisely, this impact yields significant economic benefits for enterprises that adopt such an office environment.
In the design process of this project, comprehensive consideration is given to building energy efficiency, water conservation, material conservation and land conservation. It maximizes the utilization of rainwater resources, adopts recyclable materials in construction, and reduces energy consumption through excellent envelope systems and high-efficiency facilities and equipment.
The overall energy consumption is more than 30% lower than the average value of office buildings in Shanghai, and it fully utilizes renewable energy, thus playing a significant role in promoting energy conservation and emission reduction.
Operability and Demonstration
As a benchmark project for urban renewal, Shanghai Landsea Green Center is the world's first renovated office building to receive four authoritative certifications: LEED+WELL Double Platinum +Green Building Three Stars +BREEAM. It has also become a pioneer in the field of green offices and an exemplary work. The temperature and humidity control-based healthy indoor environment system integration technology utilized in this project exhibits high reproducibility, rendering it widely applicable to both office and residential buildings. By utilizing fresh air to regulate indoor humidity, dry and wet fan coils and localized radiation to adjust temperature, a comfortable, healthy and high-quality indoor environment can be created for users. This not only enhances indoor comfort but also promotes users' work efficiency as well as physical and mental health. At the same time, extending this integrated technology to residential buildings can mitigate the drawbacks of strong air currents, noticeable noise levels, and suboptimal thermal comfort associated with conventional split air conditioning systems. When combined with centralized energy stations (such as ground source heat pumps), energy utilization can be significantly enhanced. While striving to create a people-centric, high-quality, green, healthy and environmentally-friendly living environment that meets the aspirations of the populace for a better life, we must also continue to reduce energy consumption in order to promote sustainable development and alleviate pressure on carbon emissions.
