Carbon Footprint Analysis of Buildings Based on LCA Theory Under Carbon Neutrality Goals:Taking the 3rd China International Solar Decathlon Competition as an Example

This paper focuses on the design of residential buildings oriented to the efficient use of solar energy,and selects the entries HUI HOUSE of Hefei University of Technology and Lille I University of France in the 3rd China International Solar Decathlon China Competition,based on the theory of the life cycle assessment(LCA)of buildings,and analyzes the carbon footprint from four aspects:building materials production and transportation stage,building construction stage,building operation stage,and building demolition stage.Through the calculation of the carbon footprint of buildings,the socio-economic benefits of HUI HOUSE in carbon reduction were analyzed;the result of the calculation was that HUI HOUSE achieved carbon neutrality in the ninth year,and continued carbon reduction after that,contributing a cumulative total of 947.54 tons of carbon negative in the life cycle of buildings.

Study on semantic structure of cultural and creative industry park based on internet literature

According to the information of 231 cultural and creative industry parks on the Internet literature, this research classified and studied the park elements from the text using the method of semantic Ontotogy analysis. The paper analyzes the cultural and creative industry park in the performance of type, constitution elements of geosraphical attributes, character- istics, etc. Through analysis, we found that ＂location＂, ＂form＂ and ＂rhetoric＂ are frequently mentioned in the park names. As the parks prefer to combine cultural relics with their own characters for hishlighting influence and specialties, the park locations also have certain restrictions （e.g., ＂historic sites＂, ＂ancient cities＂）. Furthermore, cultural and creative industry parks cover a wide range of contents （e.g., ＂digital industry＂, ＂ecological landscape＂）. The boundaries of the park type and content are not very clear in present China. And, the parks lack of overall planning and often have an imperfect industrial chain and other issues. Therefore, on developing cultural and creative industry parks, the overall planning and perfect industrial chain need to be focused on.

Integrating eye-movement analysis and the semantic differential method to analyze the visual effect of a traditional commercial block in Hefei, China

Eye-movement analysis was adopted to evaluate the visual perception of Chinese traditional commercial blocks,and the Chenghuangmiao block in Hefei,China,was selected as a typical case.Eye-movement data from 40 respondents viewing 14 sample pictures were recorded.The spatial elements of the sample pictures,including landmarks and commercial brands,were further extracted to analyze the visual characteristics of spatial elements and the factors that affect the respondents’perceptions of those elements.Then,the semantic differential method was used to analyze the relationship between visual preferences and psychological perceptions of spatial elements.Seventeen pairs of opposing adjectives were selected to score the intrinsic properties and visitors,feelings of spaces.The software SPSS 22.0 was used to analyze these data.Results showed that distinctive spatial elements,such as street corridors,Ma Tau Walls,and various landmarks,were the most visually attractive.In addition,the location of a given element within a picture was an important factor affecting eye movements.On this basis,strategies for improving spatial-visual effects are proposed.The strategies include emphasizing the visual characteristics of different spatial elements,considering the overall layout of spatial elements,and creating diversified spaces based on different spatial categories.
