Building Integrated Photovoltaic (BIPV) is one of the most promising renewable energy technologies. A BIPV system as a second layer of building envelopes is useful not only for the electric power generation but also for blocking solar radiation to reduce cooling load. This study aimed to explore the limitations of the automated BPS of an adaptive BIPV case study that its development conducted through a collaboration of a BIM software, a BIM-integrated visual programming environment, and a cloud-based energy analysis. The possible obstacles to BIPV design processes and the potential solutions have been discussed.
The overall aim of this study was to explore the comparative effects between obstacle's distance and obstacle's orientation parameters that cause partially shading effects and influence the potential solar power generation of a photovoltaic (PV) system. An automatic collaboration of a BIM authoring software and a cloud-based building performance analysis tool were used to simulate the annual cumulative insolation obtained from rooftop PV surfaces of eight different orientations and forty-three different distances between the BIPV and building obstacle. Two public healthcare buildings, an OPD and a ward building that widely established throughout Thailand were our case study. This study also explores that orientation and distance of a surrounding obstacle are both important parameters that influencing the annual cumulative insolation of PV surfaces but in the different contexts. The findings of this study also support decision making for BIPV designers and planners to acknowledge which the BIPV and the obstacle placement is highly effective, and which one is encountering a problem and its solution.
One basic strategy that most organizations use in differentiating itself from others is brand identi ication, which normally expresses in the form of a logo. It is predominantly required in all kinds of business, especially the corporation that pays great attention to its identity and image, a particularly real-estate developer. The main objective of this research was to compare the preferences between residents and staff members of the company toward logo design elements consisting of type font, graphic, and color. The most recent annual sales of property development businesses in Thailand were reviewed, and Pruksa brand was selected as our case study due to its top-selling margin. Through questionnaire interview, samples of two groups including 1) A hundred and ifty residents of Pruksa's low-rise and high-rise residential properties in Bangkok and 2) Forty Pruksa's staff members were randomly selected to rate three types of logo preference in terms of uniqueness, recognition, and aesthetics. The preferences concerning logo's main elements and the attitudes toward brand personality between the aforementioned two groups were analyzed by T-Test and Chi-square statistics, respectively. Guidelines for real-estate logo design aiming to represent brand personalities-sophistication, excitement, simplicity, and security-while meets their client's preferences at the same time will be proposed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
