Productive cities are effective models for urban sustainable development. This study proposes a construction mode of productive architectural surface system (PASS) and constructs a new experimental productive double-skin facade (PDSF) model. The effects of PDSF on indoor daylighting comfort are evaluated through detailed investigation and model analysis.
Productive cities are increasingly becoming one of the effective models of urban sustainable development. With the development of urban organic renewal, productive renewal of existing buildings has great development prospects and research potential. Double skin facades are a conventional concept in architecture, many studies have already been published discussing the integration of double skin facade on the thermal and electrical performance, but their integration with productive space and the corresponding daylighting performance have not yet been studied. To achieve this purpose, a construction mode of PASS (productive architectural surface system) is proposed. Then, a new experimental productive model, PDSF (productive double-skin facades), is constructed according to the PASS. A detailed investigation and model analysis are conducted to evaluate the effects of PDSF using this model, and a comparative study between measurements on a bare PDSF and a solar collector-covered PDSF was conducted in the deep winter to understand the adjustment of PDSF to indoor daylighting comfort. The main results are: (1) Adding PDSF + SC and PDSF to laboratory modules increases the area with UDI levels ranging from 100 to 2000 lux and improving the overall laboratory module daylighting quality. (2) Integrated PDSF can expand the proportion of indoor daylighting comfort zone (UDI range 500-2000 lux) in the increasing order of room CK, room with PDSF and room with PDSF + SC. (3) The PDSF prevented sunlight from reflecting light into the ground. On sunny days, PDSF effectively reduces the risk of glare and optimizes the overall daylighting quality. The thermal-daylighting balance of PDSF may need to be further researched in the future.
