CO2 Purify Effect on Improvement of Indoor Air Quality (IAQ) through Indoor Vertical Greening

Modern people usually situate inside buildings, therefore indoor air quality (IAQ) is important to living environment. In this research, we measured the transpiration rate of 50 experimental plants first, and then we chose Bird’s-Nest Fern (Asplenium nidus) as experimental subject to measure CO2 adsorption, which was one of the common indoor plants with high transpiration rate in Taiwan. We constructed an indoor 189 pots green-wall of Bird’s-Nest Fern. CO2 adsorption was measured continuously before, during and after the experiment. The experiment consisted of three tests, A: Without plants (day time), B: With plants (day time), C: With plants (with light, night). Three measurements were compared between different tests from A to C. The result of the experiment indicated that the density of CO2 was reduced from 2,000 to 600 ppm in 5.37 h of test C. In average, the efficiency of CO2 adsorption was 1.38 ppm/h each plant. The indoor temperature decreased to 2.5 °C and relative humidity increased about 2–4 %. We concluded that Bird’s-Nest Fern had superior properties to CO2 adsorption, temperature and humidity conditioning to indoor air quality improvement.

Influence of Summer Outdoor Pedestrian Wind Environment Comfort with Height-to-Width Ratios of Arcade in Taiwan

Arcade, a regional architecture style in Taiwan, is gradually replaced by sidewalk with the prevailing global trends of architecture design, thereby bringing greater challenges to pedestrians comfort. Past researches suggest optimal urban wind regime can mitigate heat island effect and enhance pedestrians comfort level. Therefore, the relationship between arcade and pedestrian wind comfort as well as the influence of arcade’s height-to-width ratios (H/W) on urban wind environment are worth a thorough research. This study takes Farglory Kyoto Community as the example. Arcades in three varied sizes are compared: In Case 1, height-to-width ratio (H/W) =1.25; Case 2(H/W=1.54); Case 3(H/W=0.75). In Aug 2016, field measurement was conducted comparable anal++ysis on outdoor environmental comfort. The field measurement result indicates that, wind environment is more stable for arcade than sidewalk, and that air temperature of arcade is 3.9 °C lower than sidewalk, thereby concluding arcade tends to generate more pedestrian wind comfort in summer. The measurement result of Thermo GEAR G100EXD suggests, during the hottest time at noon, the difference between air temperature on sidewalk and on arcade reaches 8 °C. This study also proves that in subtropical climates, arcade is more likely to provide pedestrians with higher comfort level, and that air temperature on arcade is 3.9°C lower than outdoors. The lower the height-to-width ratio is, the more comfortable the environment appears to be.

Designing “Healthy” into Green Environment for Taipei City

To achieve the goal of green environment related to an adaptive city of Taipei which is the World Design Capital 2016. We should discuss the effect of wind environment around the buildings at the beginning of design and planning phase of buildings first, for wind environment is the most important factor concerns with greenhouse and heat island effect. This research was based on a method of CFD done by Autodesk Ecotect Analysis software for simulating city building layout, study the two different building massing layout of Shezi Island in Taiwan. Results of simulation showed that the layout characterized by street block type, and therefore affect the residents’ health, activities and psychological feelings; while the case of three-sided building layout surrounded by urban of open space, on the other hand, can provide more comfortable, healthy places for rest and outdoor activities.

Designing "Friendly" into Public Park for Taipei City

Taipei City has officially been selected the 2016 World Design Capital (WDC) this year, campaigning under the slogan “Adaptive City: Design in Motion”. A successful design capital should demonstrate the different design thinking of the city. This study aimed to provide the value-added creation of friendly thinking through engineering techniques that emphasize the safety of public parks, thus forming the content of the creative design of Taipei City to develop characteristics that improve the city. First, this study investigated the functions and composition of public parks and the meaning of friendly design. The user-tool system model was applied to analyzed children playground in order to obtain the item of playground design need. Finally the friendly design guidelines for playgrounds are proposed according to entrance, perimeter containment, route, zones, equipment, signage, and surface materials.

Designing “Flourishing” into Green Environment for Taipei City

Taipei City became the World Design Capital 2016 with the slogan of “Adaptive City” and “Adaptive Design”. When seeking strategies to green environment, this study was adopted a new adaptive approach with semantic differential analysis and questionnaires to show how to design flourishing by conducting a preference cognitive test marked by “morphology” for ecological sustainability, especially in interior space. The analytic results showed that the morphological components of preference ranks from top were: repetition, proportion, gradation. And too complicated or too simple the change of morphological components did both affect viewers’ preference; also the presence of morphologies had an emotional effect on the viewers. It should be emphasized on morphological elements and form of aesthetic principles to achieve a balanced proportion of design for indoor vertical greening environment and spatial atmosphere, for the purpose of creating good flourishing visual experience.

The Practical Application of Building Information Modeling in the Construction Phase of the Building Life Cycle

With inappropriate design or construction, the functions and service life of buildings begin to decline from the day of official use until they are demolished and resulting in extremely high cumulative cost throughout the building life cycle (BLC). However, the development of building information modeling (BIM) provides a solution for short BLCs and massive cumulative cost caused by errors occurring during the building design and construction phases. BIM is an innovative technique applicable to building design and construction management that has been vigorously developed in the construction industry. The development of BIM technology is now a global trend that can not be ignored, similar to 2D CAD before. BIM can be further developed into several aspects and applied during the construction phase, most important of all, enhance the overall building functionality and save operating cost throughout the BLC.

The Importance of the Appearance Image and Cognition of Green Building

When global climate change becoming a problem that is getting worse nowadays, Green Buildings have become one of the major solutions to maintaining a sustainable environment. Because most of the public interpret the messages sent by their environment through visual appearance and images, This study aims to analyze the appearance effects of U.S. LEED and Taiwan EEWH Green Building rating systems by conducting surveys on the publics cognition of green building appearances and green building rating systems, and analyzing the relationship between green building appearance and environmental cognition. The results indicate that building appearance is a key judgment reference for identifying green buildings. However, there has been no significant relationships found between green building rating system and green building appearances so far, which may cause confusion as to the publics cognition and image of green buildings. Therefore, it is recommended that buildings appearance image should be included in future revisions of the green building rating systems.

The Relationship between Taiwan Green Buildings, Humanity and Aesthetics

The Taiwan Green Building Rating System is composed of the four categories of Ecology, Energy Saving, Waste Reduction and Health. There are also nine indicators, which are mainly guidelines but fail to consider humanity and the aesthetics of the buildings and urban environment. Based on a review of relevant literature and professional seminars, the questionnaire that was edited according to proposals relating to Green Building Aesthetics made by professionals in the field and then used to analyze the current relationship between green buildings, humanity and aesthetics in Taiwan. It is hoped, that this will enable us to fully explore the impact of humanity and aesthetics on Taiwan Green Buildings, while further demonstrating the importance of humanity and aesthetics. According to the questionnaire results, 76.8% of the respondents disagreed as well as kind of agreed and disagreed with the idea that the current Green Buildings in Taiwan has comprised of the concepts of Humanity and Aesthetics; 72.1% of the respondents considered Humanity and Aesthetics to the rating of Green Building very important and important; 81.2% of the public extremely agreed and agreed with the idea that Humanity and Aesthetics should be included in Green Building. The findings of this research indicated that most of the public considered that there were only few Humanity and Aesthetics considerations in the current Green Buildings in Taiwan and agreed that it was important to include Humanity and Aesthetics in Green Buildings.
