The Common

Solar-shading systems play various roles to the users of public buildings and may vary from user to user but some of the common user’s needs for these systems include; thermal comfort, energy-saving, daylight, and glare reduction. Understanding these needs can help Designers and Architects select from a wide array of Solar-Shading types and see which of them serves the needs of the users better. The Types of Solar-Shading Systems include either internal systems which are placed inside the building or can include external systems which are placed to the outside of buildings. To clearly understand the role Solar Shading Systems, play to satisfy Users’ needs, a case study of a Public Building in Nairobi, Kenya; Britam Towers, was selected. The case study found out that architects, designers, and developers play a preeminent role in coming up with projects that can better serve the User’s needs by creating designs that better suit the needs of the users have for using such Solar-Shading Systems. These designs may vary from building to building, region to region but the main withstanding factor to be noted is the functionality issue, as the Solar-Shading Systems should be able to meet the needs of users effectively and in turn, increase the user’s satisfaction.

Space Cooling

Space cooling is currently the fastest-growing end-user in buildings. The global warming trend combined with increased population and economic development will lead to accelerated growth in space cooling in the future, especially in China. The hot summer and cold winter (HSCW) zone is the most densely populated and economically developed region in China, but with the worst indoor thermal environment. Relatively few studies have been conducted on the actual measurements in the optimization of insulation design under typical intermittent cooling modes in this region. This case study was conducted in Chengdu—the two residences selected were identical in design, but the south bedroom of the case study residence had interior insulation (inside insulation on all opaque interior surfaces of a space) retrofitted in the bedroom area in 2017. In August 2019, a comparative on-site measurement was done to investigate the effect of the retrofit work under three typical intermittent cooling patterns in the real-life scenario. The experimental result shows that interior insulation provides a significant improvement in energy-saving and the indoor thermal environment. The average energy savings in daily cooling energy consumption of the south bedroom is 42.09%, with the maximum reaching 48.91%. In the bedroom with interior insulation retrofit, the indoor temperature is closer to the set temperature and the vertical temperature difference is smaller during the cooling period; when the air conditioner is off, the room remains a comfortable temperature for a slightly longer time.

Targeting at students randomly selected across all departments and all years at one university located in northern Taiwan, this research based on hierarchical regression analysis aims to investigate whether or not global warming awareness education exerts a positive effect on research participants’ energy-saving cognition and attitude. the results indicate that the 8 hypotheses proposed are all supported. Firstly, green education courses and global warming awareness videos have significantly positive impact on participants’ cognition and attitude as compare to their peers who did not take the courses or view the videos. Secondly, the participants’ scientific literacy positively influences their energy-saving cognition, which in turn positively impacts on energy-saving attitude. Furthermore, energy-saving cognition plays a completely intermediate role between scientific literacy and energy-saving attitude. Results mentioned conclude the contributions of this research.

Labeling System

Despite China's significant progress in energy saving renovations, during the past 10 years, problems about inefficiencies remain. In the Netherlands, the energy labeling system (ELS) effectively linked policy objectives and market forces, combined with the stepped tariffs aimed at the performance of energy-saving renovation, generating a virtuous cycle of housing energy efficiency upgrading. China may draw the experience from Netherlands. In this regard, the authors probe the market effect and operating mechanism of the Dutch ELS and the stepped tariffs. The theory of multi-level governance (MLG) is introduced to the filed investigations both in China and the Netherlands. Based on the group-interviews and depth-interviews with the officials in related agencies and the residents of retrofitting housing, the authors obtained first-hand information to ensure a close case study on Netherlands' housing ELS and its implementation, in order to provide some enlightenment for China's existing housing renovation and low carbon development.
