The objective of this study was to learn views from design teams, housing developers and users for housing development green space quality that could best enhance occupant well-being and real-estate value addition. Through literature review, 26 landscape design and service factors were identified and tested via a questionnaire survey conducted in Taiwan. Participants (N = 380) evaluated the importance level of the proposed factors with five-point Likert scale. Friedman Ranking Test and Kruskal-Wallis Test were used to analyse data. The results showed that ease of maintenance, regulation compliance and energy saving were the top factors for all participants. These are the economic advantage, bidder characteristics and environmental awareness concerns. Life cycle design and water retention and detention factors were evaluated as the critical factors from the potential housing developer and buyers. Green infrastructure connection and neighbourhood connection were ranked as very important factors for landscape architects. Landscape architects to practice with license and use LIM/BIM in project was particularly expected by the potential housing buyers with high importance level. The preliminary findings of this research can assist public housing agency and private developers for policy and decision making effectively in future housing development green space projects.
Development of acoustics in research and field applications in Taiwan has been well established and aligned with developed countries world-wide. Taiwan has comprehensive acoustic regulations and standards for residential and hospitality building types and stringent environmental noise protection ordinances. It is the only country that has specific noise regulation for 20 Hz to 200 Hz. The Taiwan Acoustical Association (TAA) was established on 1987. Since then, thirty-two biannual meetings have been successfully held. Auditory and speech communication, building acoustics, mechanical acoustics, ultrasound, underwater acoustics, noise and vibration, as well as bio-acoustics and other related acoustic topics were covered in these meetings. According to the Taiwan Patent Search System (English version), about 187 acoustic related patents have been granted since 2004. In terms of research institutes, at least 14 top universities in Taiwan have specific major for acoustic studies. At National Taiwan University of Science and Technology, there is an architectural acoustics program under the Department of Architecture. Its team has been involved in the world-renowned performing arts center projects such as Taichung Metropolitan Opera House, Weiwuying National Kaohsiung Center for the Arts, Taipei Performing Arts Center and Taipei Pop Music Center. It can be concluded that research and field applications of acoustics in Taiwan has been valued by the people and will be continued and tuned to world-wide standards!
Respite place in healthcare facility has been introduced and promoted in USGBC LEED to reduce stress and fatigue for caregivers, patients, and their families. Studies showed that people stay in natural environment can experience a sense of wellbeing and also suggested gentle stream water sound is highly associated with “relax” listening impression. Thus, as gentle stream is one of the familiar nature elements and is often used as a landscape architecture element for relaxation along with greens in respite place, the objective of this study was to learn the effect of the relaxation state with gentle stream water sound by studying the alpha brainwave response and physiological responses such as heart rate and blood pressure of 20 participants. During the evaluation, stress inducing period and relaxation period were conducted. Two-sample t-test was used to find out if there were any significant changes in participants’ brainwave and physiological responses. The results showed that based on alpha brainwave, more female participants experienced relaxation state than males. After listening to the water sound, the systolic blood pressure showed the most obvious changes, and heart rate is slower.
