“…To test the extent to which the QMs and FMs were capable of readily costing preventative, appraisal, or rework actions, a series of items was presented with a six-point Likert scale to evaluate each item in terms of its level of complexity. The scale ranged from Very Simple (1) to Not Feasible (6). The questions were derived from green-building projects' quality plans, commissioning plans [44,45,70], and studies based on the CoQ [23][24][25].…”

“…The expectations in a green building are more elevated as there are energy and water saving requirements, improved indoor environmental quality and compliance for environmentally conscious material selection and waste reduction. However, several authors pointed out green buildings did not meet the energy and water savings performances in the operational phases [5][6][7][8], nor on indoor environmental quality in actually promoting the building end-users' well-being [9,10]. Furthermore, the green building rating systems had a slight impact on tackling construction waste management as a result of weak appraisal measures [11].…”

The quality performance of a green building will have an overarching effect on its objectives because of the high compliance needed to achieve superior performance expectations. Achieving sustainability objectives is challenging and requires the collaboration of diverse professionals that resume unique responsibilities. In this study, the different managerial practitioners involved in green-building projects were investigated in terms of their awareness levels regarding the quality performance measures, their perceived abilities to influence quality failure consequences, the degree to which the cost-of-quality (CoQ) of components can be evaluated, and the effect the sustainability traits have on the quality performance. Accordingly, a survey approach was adopted, and the results were analyzed using Pearson’s chi-squared (χ2) test, the relative importance index (RII), Mann–Whitney U-Test, and Student’s T-test. According to the results, the priorities of the different managerial types and their overall impressions of cost computability were different, which needs to be considered when CoQ evaluations are done based on practitioners’ views. In addition, the sustainability traits of green buildings impact achieving quality metrics with the consequences of design rework occurring in the construction stage may lead to denouncing sustainability traits. The results of this research study reveal the need to consider the differences between managerial types when evaluating CoQ for projects and the increased sensitivity for such evaluation in a green building context. The paper contributes to underscoring the important connection between quality performance and sustainability traits of a green building project and calls for researchers to formulate methods with more rigor to reach a set structure for quality cost accounting as an industry standard. Intricate evaluation methods will enable strategic decision making on quality performance budgets to be more substantiated.

“…Newsham et al (2013) 61 supported that green buildings will produce higher ratings of occupant environmental satisfaction will have temperatures closer to thermally neutral and will have lighting conditions closer to recommended practice and provide more access to daylight satisfying the occupants. Chokor et al (2015) 62 examined occupant satisfaction and revealed significant results exhibiting higher occupant satisfaction in terms of thermal comfort, lighting level and acoustic quality. The only study different than those mentioned in the literature and in this study was 63 resulting an equal satisfaction for LEED certified and non-LEED buildings.…”

Zeynep IŞIKBu çalışma, LEED yeşil bina sertifikalı bina projelerinde "İç Ortam Kalitesi" parametrelerinin farklı paydaşların bakış açıları ile "kullanıcı memnuniyeti" ve "proje maliyet performansı" gibi anahtar performans göstergeleri bakımından karşılaştırmalı bir analizini sunmaktadır. Bu bağlamda, "İç Ortam Kaliesi"nin, "kullanıcı menuniyeti"ni belirleyen ısı konforu, gün ışığı, akustik kontrol vb. unsurlar ÖZThis paper presents a comparative analysis of different stakeholders' view of LEED certified building projects' Indoor Environmetal Quality (IEQ) parameters from the perspective of such key performance indicators (KPIs) as "occupant satisfaction" and "project cost performance". Within this context, a comprehensive literature review respresenting the studies on Indoor Environmental Quality with a relationship to occupant satisfaction in terms of thermal comfort, daylighting, acoustic control and project cost premium and investment performances etc. was conducted and an Analytical Hierarchy Process (AHP) model was constructed indicating the effects of IEQ parameters on Occupant Satisfaction and Project Cost Performance. The ratings of the effects of the parameters were collected by a brainstorming workshop with the participation of different stakelholders of sustainable design such as researchers, practitioners and LEED consultants. The data were analysed conducting AHP analysis which is a multi crtieria decision method. The analysis results revelaed that thermal comfort, interior lighting, daylight, acoustic performance and environmental tobacco smoke control parameters had the highest rankings among occupant satisfaction whereas low emitting materials, daylight, thermal comfort and acoustic performance were the ones for project cost performance.

“…An independent third-party rating system evaluates the selection from project stakeholders from concept to completion phase. On the other hand, Leadership in Energy and Environmental Design (LEED) from US Green Building Council (USGBC) explores sustainable implementation during building life cycle before the rating ( Chokor et al., 2015 ; Kim et al., 2017 ). A similar concept was also found in other countries such as Green Star rating tools in Australia, ITACA in Italy ( Asdrubali et al., 2015 ), Comprehensive Assessment System for Building Environmental Efficiency (CASBEE) in Japan, Building Environmental Assessment Methods (BEAM) in Hong Kong, and Green Building Index in Malaysia to Green Mark in Singapore ( Zuo and Zhao, 2014) .…”

Green building rating system has been used by many countries around the globe to certify the green buildings. However, little evidence has confirmed that stakeholders understand the theory and practical implementation of green building rating system, particularly in Indonesia. Thus, the paper aims to evaluate stakeholders knowledge of green buildings, and to propose recommendation for green building direction for the government. The result shows most of the professionals in this sector prefer considering environmental issues as the primary concern in developing the new building over social and economic aspects of sustainability. Despite their awareness of this concept, limited experience from building owner and rewards are the two main barriers to the steady progress of professionals taking certification of green building. This study also shows that the government and green building council of the country needs to evaluate the method to promote the use of green building concept and to encourage professionals taking the certification.
