This building received a mention for the Sustainable Renovation Grand Prize of the Green Solutions Awards International 2020-21.
The Project, located in Siqi Park, Kunshan City, Jiangsu Province, functions as a civic morality museum and adopts frame structure. Built in 2004, the existing building originally functioned as a tea house, and was vacant before the refurbishment. Based on the refurbishment method similar to Chinese “acupuncture and moxibustion” therapy from a point to an area, the Project not only integrates the concept of green building to reinforce and transform the building, but also retains the small and exquisite Jiangnan style of the existing building. Specifically, the building envelope structure is reconstructed to the structure of energy-saving and interior thermal insulation, creating more than 65% overall building energy-saving rate. For HVAC system, the Variable Refrigerant Volume (VRV) system is adopted, in which the fresh air is supplied by the total heat exchanger that performs the air purification function of haze removal and PM2.5 filtration. The whole building adopts LED energy-saving lighting. The building is also equipped with photovoltaic power generation and solar street lights in order to make full use of renewable energy. In addition, for the sustainable development of the building and its surrounding environment, Michelia trees planted in the existing building are retained according to local conditions, creating a compact and unique indoor landscape. The outdoor environment is green and beautiful, with 60.45% greening rate. The design concept of “Sponge City” is integrated into the transformation of the park around the building. Measures such as grassed swales, rainwater garden, permeable pavement and rainwater recycling pool are taken to effectively release the ponding at the plot and form a rainwater recycling system in the park for greening irrigation. At the same time, the building intelligent system is introduced to continuously enable the intelligent operation of "City Park" by means of equipment control, air quality monitoring and real-time display. After operation, indoor and outdoor environment monitoring data are displayed on large screen to effectively improve the quality of indoor and outdoor environment.

Owner approach of sustainability
Kunshan Civic Morality Museum is divided into six areas: Preface Hall, Morality Advocating Path, Virtue of Kunshan, Moral World, Walking with Morality, and One Heart with One Mind. Based on modern technologies such as sound, light and electricity, as well as various forms of representation such as texts and pictures, the museum is built into a new era civilization practice base integrating moral culture propaganda, apologue display, moral education experience and other functions. It is also an important carrier of deepening citizen moral education in Kunshan City.
The Project aims to build an "ingenious and exquisite" civic morality museum after completion. Through green refurbishment works, it will become a pilot demonstration project of green technology applications such as green refurbishment, Sponge City Park and intelligent building in Kunshan City and a visiting and exhibition experience center. At the same time, it will also be used as the practical education base of moral culture visit and exhibition, voluntary activities and “Red Tour” party member activities.
Compared with similar projects, the Project, based on the comfortable behavior characteristics of human, focuses on improving the comfortability of the reconstructed building, including lighting environment, acoustic features, thermal comfort conditions, air quality and health, physical and psychological health, as well as harmonious coexistence of building and natural environment. The physical technologies are applied to the building, so that it can achieve the goal of green building with comfortability, sustainable health, energy saving and environmental protection on the premise of meeting the space and function requirements of the museum.
Architectural description
(1) Green refurbishment
Based on the refurbishment method similar to Chinese “acupuncture and moxibustion” therapy from a point to an area, the Project not only integrates the concept of green building to reinforce and transform the building, but also retains the small and exquisite Jiangnan style of the existing building. Specifically, the building envelope structure is reconstructed to the structure of energy-saving and interior thermal insulation, creating more than 65% overall building energy-saving rate. For HVAC system, the VRV system is adopted, in which the fresh air is supplied by the total heat exchanger that performs the air purification function of haze removal and PM2.5 filtration. The whole building adopts LED energy-saving lighting. The building is also equipped with photovoltaic power generation and solar street lights in order to make full use of renewable energy. In addition, for the sustainable development of the building and its surrounding environment, Michelia trees planted in the existing building are retained according to local conditions, creating a compact and unique indoor landscape.
(2) Sponge City Park
The Project is located in Siqi Park, with beautiful and green environment and greening rate of 60.45%. The design concept of “Sponge City” is integrated into the transformation of the park. Measures such as grassed swales, rainwater garden, permeable pavement and rainwater recycling pool are taken to effectively release the ponding at the plot and form a rainwater recycling system in the park for greening irrigation.
(3) Intelligent building
The building intelligent system is introduced to continuously enable the intelligent operation of "City Park" by means of equipment control, air quality monitoring and real-time display. After operation, indoor and outdoor environment monitoring data are displayed on large screen to effectively improve the quality of indoor and outdoor environment.
Building users opinion
The Project is open to the public free of charge as a Civic Morality Museum. In the course of operation, visitors are regularly surveyed with questionnaires, including customer service level, sanitation, parking management, indoor thermal and humid environment of green building, noise environment, light environment, traffic convenience and property service level. According to the survey results, the overall satisfaction is more than 95%, and the property management company takes corresponding improvement measures timely.

Smart Building
Urban environment
The Project is located in Siqi Park, Kunshan City, with smooth and convenient traffic. At the entrance of the park, the bus stop, motor vehicle parking spaces, bicycle parking spaces and urban shared bicycles are provided to facilitate the green travel of surrounding residents. The project site is surrounded by a commercial and residential complex integrating commerce, catering, office, residence and leisure, with complete living facilities. There are appropriate public open space and humanized streets.
Siqi Park, where the Project is located, is one of the pilot areas of Sponge City. By optimizing the park drainage system, adding permeable brick pavement, grassed swales, rainwater recycling pool, low elevation greenbelt and other facilities, Siqi Park is perfectly integrated with the surrounding park landscape, commercial supporting facilities and residence community. Efforts have been made to improve the overall landscape and create a green and beautiful environment.

Parking spaces
In the Project, the layout of parking facilities at the entrance of the southeast side of the park is optimized. There are 14 free motor vehicle parking spaces and 18 automatic paid motor vehicle parking spaces added, without occupation of walking space and activity space in the park. At the same time, the park is provided with non-motor vehicle parking spaces and shared bicycle parking areas in the southwest of the park to facilitate green travel of surrounding citizens.
