Museums, galleries or other cultural venues are often considered providers of public goods. When we talk about climate change, sustainability and other issues, the role of these units is often ignored, and these venues are even exempted from the supervision of related issues. Yet museums can be among the most carbon-intensive buildings in a city. how to say? Because the museum is able to properly preserve its collections by strictly controlling temperature and humidity, it has fallen into an air-conditioned "doom loop"[1]. In the process, more energy is used and more carbon dioxide is emitted, which in turn leads to climate change and extreme temperatures. When faced with drastic changes in temperature, more energy is needed to maintain and control the indoor environment, creating a vicious cycle. In addition, environmentally harmful chemicals are also used during the restoration of cultural relics, artworks, etc., further causing environmental damage. Most museums have strict temperature and humidity controls, so how to reduce carbon emissions has become a big challenge. Find the sustainable operation model of the venue with the help of "digital twin", the experience of the Charles H. Wright Museum in the United States. Ten years ago, Leslie Tom visited the Charles H. Wright Museum of African American History in Detroit and discovered the methods used to develop sustainability. Resources are quite scarce. In 2015, when he became the chief sustainability officer (CSO) of the museum, relying on his background in architecture and design, he discovered that due to a fire in the architect's office, the museum lost the project blueprints at that time. In 2019, in order to create a "wisdom museum"
