Abstract: The operation of BIPV case study aimed to the environmental effects of the architectural design on landscape, which estimated the usability between human behavior and renewable energy on the design management. The BIPV project was the landmark of the local city hall, when it was built in Tainan Country in 2005, and it was the first BIPV research model in Taiwan. The multifunction covered three aspects: renewable energy usage, green site planning and underground parking lot. The BIPV working system was a hybrid system, which used 219 pieces PV modules by glass-to-glass type, and had total PV capacity of 24.09kWp. In the PV renewable energy, the DMY data was from 1.42 to 1.82 (kWh/day/kWp) and the PR value was form 36.6%-49.2%. For consideration of each evaluated factors, the architectural esthetics and energy design of the BIPV research case was not perfectly balance in the project. The citizens could accept this modern urban park as a friendly design for usage. But the PV power efficiency, the excessive design and inexact distribution decreased its power performance too much. Ultimately, the research presented an intensely interesting data for Taiwan BIPV development between the PV industry and architectural design.

Abstract: Based on the local acceleration effect generated by air flow passing through obstacles, this study explored changes in the surrounding wind field of buildings and the possibility to develop the potential wind energy by installing wind deflector in building according to the concept of “dredging” to facilitate the integrated application of small-scale wind turbine in buildings. With a nine-story building as the research subject, this study used the wind deflector installed on the building roof to generate the contracted flow effect (Venturi effect) to accelerate the air flow, change wind field and thus increase the possibility of wind power use as well as the power generation efficiency of the small-scale wind turbine. This study applied the numerical simulation method to discuss differences in three cases of no wind deflector (N-WD), installing lower wind deflector (L-WD) and installing upper and lower wind deflectors (2-WD). It also evaluated the impact on wind field and contribution to wind speed acceleration.

Abstract: This study is a 3-year national research project. The objective of this study is to examine the influence of formaldehyde and VOC emissions with different application ratios of ultra-low emission (ULE) green building materials(GBMs), and their impact on human health in indoor environments. The testing methods for aldehyde and ketone substances, and VOC substances used in this study are referenced from the ASTM D6670-01 regulations by full size chamber test method, and the ISO 16000-3 and ISO 16000-6 regulated aldehyde and ketone substance, and VOC sampling and analysis methods. Experiments are conducted at 0%, 30%, 50%, 80% and 100% (5 groups) ratios of ultra-low emission (ULE) green building material used, and the emissions are analyzed. The results show that the higher the utility rate of ULE green building material, the more the interior concentration of TVOC can be effectively lowered. Using at least 30% ULE green building material can achieve indoor air quality that is less than the TVOC value standard of 3 ppm set by the Environmental Protection Administration of Executive Yuan, Taiwan. However, under the standard of 300 ug/m3, set by the World Health Organization and the GreenGuard children’s standard of 220 ug/m3, our research shows that the experiment groups using 30%, and not using (0%) ULE green building material, present a health risk, based on the above standards. However using more than 50% ULE green building material can effectively lower the VOC emission level, indicating that by increasing the use of ULE green building material, the IEH can be maintained.

Abstract: This study coats complex colloid mixed with Sn-xAl powders and polyethylene on glass to examine the shield effect on electromagnetic interference (EMI). In addition, the sputtering specimens and powder coating specimens were compared. The results show that adding Al to the Sn-xAl powders can increase the electromagnetic interference (EMI) shield at lower frequencies. Notably, the number of cavities in the coating layer increased with the coating thickness, with the result that the EMI shield could not improve with an increase in the coating thickness at higher frequencies. However, the EMI shield of sputtering films had a tendency to increase as the thin thickness increased. The Sn-40Al undergoes a dispersing effect which forms a fine overlapping structure, thereby improving the low frequency EMI shielding. In addition, the Sn-20Al powders possessed the properties of a small particle size, closed structure and higher electric conductivity which improved the high frequency EMI shielding. For the sputtering films, the annealed treatment not only had higher electric conductivity but also increased the high frequency EMI shielding.

Abstract: Sn, Al and Cu not only possess electromagnetic interference shield efficiency, but also have the acceptable costs. In this study, sputtered Sn-Al thin films and Sn-Cu thin film were used to investigate the effect of the crystallization mechanism and film thickness on the electromagnetic interference (EMI) characteristics. In addition, the annealed microstructure, electrical conductivity and EMI of the Sn-xAl films and the Sn-xCu films were compared. The results show that Sn-Al film increased the electromagnetic interference (EMI) shielding after annealed. Sn-Cu films with higher Cu atomic concentration, the low frequency EMI shielding could not be improved. After annealing, the Sn-Cu thin film with lower Cu content possessed excellent EMI shielding at lower frequencies, but had an inverse tendency at higher frequencies.

Abstract: The window glazing system provides comfortable living environment for residents and also exhibits the esthetics of architectural design. Its quality is dependent upon glass material selection; there are many factors determining glazing material selection, which might further affects the building safety and energy savings. An analytic hierarchy process (AHP) is used to analyze the trade-off of these impact factors. In the survey, both positive and negative impact factors on the glazing material selection are considered. The results, based on 40 expertise questionnaires, indicated that “performance”, in overall, was perceived to be most important core selection criterion for the green glazing material, but among all assessed items, “hazardous substance release” was concerned the most. The “appearance” was regarded as a minor factor in this analysis. In addition, BIPV alternative was also ranked in the first position regardless of criteria weight variations. The results provide valuable information for building material manufacturers, architects and interior designers in selecting glass material in their the glazing system.
