“…According to Hodgson, 5 LEED basically disregard the acoustical environment requirement and this has unfortunately made it very unlikely for architects and designers to consider acoustics as an important aspect of green buildings. 17,18 This was confirmed by Lee and Guerin 19 in their study on occupants' satisfaction and performance in LEED-certified buildings. The study explained that LEED IEQ requirements address only on issues related to mechanical aspects of the indoor environment such as indoor air quality (IAQ), low emitting materials, indoor chemical and pollutant source control, controllability of systems, thermal comfort and daylighting systems.…”

Green building rating system outlines many requirements to be considered in order for a building to be certified as one. However, the rating tools failed at truly addressing the acoustical aspect which in turn deteriorates the acoustical quality in green buildings. As preliminary stage of this study, the objective is to assess the acoustical performance of three green office buildings in Malaysia in comparison to selected standard acceptability criteria. Four spaces containing meeting rooms and open-plan offices were selected from each green building as subjects. Assessments were limited to selected acoustical parameters of background noise level, noise criteria, reverberation time and speech transmission index. The background noise levels were found to be within acceptable criteria range despite some meeting rooms that exceeded the maximum recommended level. However, noise criteria ratings found most of the spaces to be below the acceptable noise criteria. Reverberation times data varied from satisfactory 0.7 s to unacceptable 1.5 s. Nonetheless, the background noise, noise criteria and reverberation time data collected were found to be unbiased by the volume of the space. Speech transmission indexes were found to be ample within good and fair speech intelligibility range while still maintaining its normal tendency of decreasing with distance.

“…Most researchers believe the certified GBs perform better than conventional buildings in terms of IEQ and energy use [148][149][150]. There are four main variables highlighted in GBRSs to improve IEQ: thermal quality, acoustic quality, visual quality, and indoor air quality (IAQ) [151][152][153]. Lin et al found the satisfaction of users in certified GBs is higher than conventional buildings in terms of thermal comfort and IAQ [154].…”

Since the energy crisis in the 1960s, crucial research and activities were spurred to improve energy efficiency and decrease environmental pollution. To deal with the various problems the construction industry are facing, the concept of green buildings (GBs) has been gradually shaped and put forward all over the world, and green building rating systems (GBRSs) have been developed. The concept of GBs covers a wide range of elements, and its definition is constantly updated as the construction industry develops. This paper compares the development of backgrounds and statuses of green building development in various countries. It also presents an overview of the green building development situation within these countries, summarizing two influences for GB development: one external and the other internal. External factors include GB development policy support, economic benefits, and certification schemes. Internal factors are the development and application of GB technology, the level of building management, and how users interact with the GB technology. Currently, 49 worldwide green building standards and application have been sorted out, including 18 standard expert appraisal systems. Moreover, it discusses the research results and lessons learned from green building projects in different countries and summarizes their achievements and challenges. To correctly understand and use green building technology, it is essential to improve the policy and incentive system, improve the professional quality and technical ability of employees and accredited consultants, constantly develop and update the evaluation system, strengthen technological innovation, and integrate design and management. This paper aims to draw a clear roadmap for national standard development, policy formulation, and construction design companies, provide solutions to remove the obstacles, and suggest research direction for future studies.

“…Generally located at the center of the building, the atrium can be acted as a key circulation and transition space to proceed to other spaces (Wood & Salib, 2013;Pitts, 2013;Passe & Battaglia, 2015). It also gives an impression of large volume and has the potential to provide good air circulation and light penetration towards indoor comfort within the space (Jalil et al, 2014;Bai et al, 2015;Moosavi et al, 2014;Moosavi et al, 2015). Nowadays, the atrium is widely used in residential, commercial, and institutional buildings and not only acts as protection from the climate conditions but also creates a significant visual effect on the existing space.…”

Atriums, in most conditions, are considered the heart of buildings, the main spaces where different functions and activities are held. Nowadays, various atrium designs are incorporated in the building, varying from pyramidal to barrel vault. Therefore, it is of great importance to study the basic characteristics of sound fields in such spaces and their related materials. This research aims to determine the effect of various skylight geometry configurations on the atrium’s acoustical performance. Next, an acoustical performance evaluation of the effect of skylight materials was performed by using computer simulation. Four selected atriums with different types of skylight geometries modeling and respective materials, i.e., glass, polycarbonate, and acrylic, have been used in this acoustical simulation. From the results, it can be concluded that an atrium with a pyramidal skylight provides a better reverberation time for music purposes. In contrast, all atriums’ models’ speech transmission index values were almost identical. However, no significant acoustical performance can be found in different used materials. The result also indicates that the shape of the atrium has a higher effect on the acoustical performance than the different materials used.
