This paper discusses the importance of green cleaning for green buildings during the operations and maintenance stage. The investment on green buildings is often driven by the aim to reduce energy consumption. However, many tend to overlook the importance of the operations and maintenance aspect of the building, particularly the green cleaning aspect. Green cleaning is a major contributor to Indoor Environmental Quality (IEQ) where IEQ is one of the important criteria that should be considered during the assessment of green building performance. In Malaysia, there is no specific regulation set for green cleaning. Green Building Index (GBI) tools itself does not specifically highlighting green cleaning in their assessment tool. Thus, based on literature review, this paper discusses the benefits of implementing green cleaning and how green cleaning can contribute to achieving better green building performance.

Hospitals are the major contributor to environmental corruption and the biggest drain onenergy in their life cycle because they are complex, multifunctional giant facilities. Several recent studieshave been carried out to find the most suitable solutions to reduce energy consumption provide it on-siteand contribute to supporting economic, environmental and social aspects. The reason for the slowmovement of green buildings for hospitals is to focus on a suitable design for the complex function thatdeals with the local climate, natural resources, economy and cultural values and avoid the one-size-fits alldesign. This made the solutions used multiple and varied, different for greening of the hospital and put theresearch in the absence of a clear perception of the mechanisms of the application of green architecture inhospitals and this identified the problem of research. Therefore, the study looked at an analytical study ofexisting project models designed according to the strategies and standards of green architecture todetermine the strategies adopted in each project, and by adopting the analytical method after determiningthe strategy used in each building to achieve the green architecture and then comparing them according tothe standards adopted using the global LEED system Green Building Council. The results that will bereached are the mechanisms of applying Green Architecture to Hospitals.

Occupant Satisfaction

Universities spend billions of dollars on green buildings as a sustainability commitment. This research investigates occupant satisfaction with indoor environmental quality (IEQ), building design (BD), and facilities management (FM) in five highly ranked green higher educational buildings in the subtropical climate of Australia, in comparison to nine non-green counterparts. The results disclose that the green building users were more consistently satisfied than the non-green building users with BD&FM elements, such as design, needs from facilities, building image, cleaning, the availability of meeting rooms, and storage. On the other hand, the study revealed weaknesses of green buildings in IEQ, such as noise, ventilation, and artificial lighting. The individual environmental control positively correlated with satisfaction in non-green buildings, but did not significantly affect satisfaction in green buildings. This study also identified the influences of non-environmental factors on occupant satisfaction, such as gender, age, sitting close to a window, hours spent in the building and in the workstation, and the number of people sharing office space. The research provides evidence and guidance for investing in, designing, and managing green educational facilities.

And Control

The demand for green buildings in the property market is substantially increasing. The motivation for the investment on green buildings ranges from environmental concerns and social benefits to financial savings during the operational stage. However, these perceived benefits have been argued to be mostly theoretical and yet to be empirically proven. There is often a performance gap between the expected and the actual measured performance of green buildings once operational. Green buildings simply fail to perform as to what it was intended despite the thorough design and technological considerations put at the initial stage of their development. Hence, by reviewing various literatures, this paper targets to indicate and discuss the factors that hinder green buildings from achieving their fullest performance potential. Six theoretical factors namely miscommunication, technologies used, modeling tools, construction process and handover, occupant behavior and management and control were identified from various literatures. The findings in this paper will be a commencement for further studies pertaining to non-performance of green buildings.

  Conventional buildings consume large amounts of energy and are the source of greenhouse gas emissions contributing to climate change. The shortage of green buildings in Pakistan have been said to be due to shortage of knowledge of the benefits of essential green building materials and the absence of  a regulatory framework. The study is qualitative and quantitative and is divided into two parts. This review paper focuses on awareness in the Pakistan's local construction market concerning green buildings through a survey questionnaire. Data collection procedure consists of 60 questionnaires related to green building construction awareness and priorities within Karachi's construction sector. Also, a focus group and personal interviews conducted with at least 5 professionals working in local construction projects are analyzed. The research questions formed from detailed literature review were analyzed and found that energy conservation, environmental/resource conservation and improving indoor environmental quality are major driving factors for green building development. Similarly, there is a lack of knowledge of green construction methods and regulations and lack of support from the government. This has been found as the major barrier in going towards green construction. We recommend policy directions towards this end and elaborate points of concern to the authorities.

Environmental Quality Assessment

Michigan State University and the Michigan Department of Natural Resources established a partnership for sustainable park planning in October 2011. The purpose of the partnership was to enable students in the design fields to work on real-world projects and provide practical solutions. One of the notable projects was to assess old historic buildings in one state park and propose renovation plan to improve its indoor environmental quality and energy efficiency. The buildings in the park functioned as the traveler’s destination in the 1920s and still preserve original interior and exterior features. The team of undergraduates and faculty in interior design visited the park and assessed the interior and exterior conditions of two of its buildings. They used an assessment tool which was designed on a basis of the elements in the indoor environmental quality category (IEQ) of the US Green Building Council’s LEED. Results revealed that the indoor environmental conditions of the buildings should be improved. The energy efficiency of the buildings was low. Based on this assessment, this study offered practical suggestions for improving the building’s indoor environmental quality. This study also proposed an assessment tool for the historic buildings in the state parks in Michigan to assess current indoor environmental quality of those buildings.

t has been argued that green buildings have a better indoor environmental quality than conventional buildings and that this translates into a more satisfying workplace for the building's occupants and, inturn, a more productive workforce. Assessing a building's cost effectiveness means taking into account all the costs that will be incurred during its life cycle not just development costs. People found no evidence to believe that green buildings are more comfortable than conventional building. In fact, the only difference between the buildings was that occupants of the green building were more likely to perceive their work environment as warm, and occupants who felt warm were more likely to describe their work environment as poor.

Abstract Background. The recent pursuit of energy conservation, emission reduction, and sustainable development are the demanding aspect in green building construction. Green building concept becomes important in the current building life cycle to mitigate environmental issues. In this way, a strategy for surveying the performance of a green structure is attractive. Consequently, this investigation intends to build up a methodical methodology for distinguishing the elements that decide the effective development and activity of a green structure and makes a technique for assessing green building execution.Methods. To accomplish these objectives, a comprehensive literature review was first conducted, followed by determining the performance of a green building to create a qualitative fuzzy set of performance metrics. A cloud model was used to analyze the factor hierarchy using weighted entropy to quantify the performance of a green building. Ultimately, an inside and out contextual analysis was led to check the exact discoveries.Results. A green building performance index that was created based on expert evaluations and weighted the indexes subjectively and objectively. Likewise, a standard cloud yardstick was also created in the comprehensive cloud. The sustainability of the building was qualified and assessed by comparing cloud images with the standard cloud. It has been analyzed that, the execution measurements and persuasive components make appraisal models for a green building. This investigation can help the development business to distinguish and manage issues that emerge in building green buildings. The coherent framework that the researchers have developed for assessing green buildings provides a solid foundation for further research into sustainability and green building operation. The result indicates that the industry acquires benefit by suggesting effective measures that can be implemented in all stages of green building construction.Conclusion. The analysis results demonstrated that this investigation builds up a novel exhibition appraisal of a green building which makes a target establishment for assessing building execution. Additionally, the findings are helpful for industry specialists to improve green building construction. Besides, the outcomes give significant data to governments and other invested individuals to create target models for green building development programs.

Different Levels

Nowadays, the concept of green building is no longer an alternative but a necessity. The acceptance of a building as “green” depends on having a certificate. LEED is one of the widely used green building certification systems in Turkey. The main objective of this study is to find out whether there were statistically significant differences between the credit achievements of 105 newly constructed and certified buildings in Turkey, which were certified according to four different levels, and to determine which of these credit achievements are weak. For this purpose, Kruskal-Wallis and Mann-Whitney U tests were performed and the findings were interpreted. Findings revealed that the highest level of achievement of these buildings was in sustainable sites, water efficiency, innovation in design, and regional priority credits, while the lowest level of achievement was in energy and atmosphere, materials and resources, and indoor environmental quality credits. Analyses revealed that the achievements in the energy and atmosphere, materials and resources, and indoor environmental quality credits of green buildings are relatively low when compared to the ones in other credits. There may be several reasons behind these low levels of achievement such as poor green culture, high investment cost of necessary systems, absence of reusable, recycled, and renewable materials. If these problems, most of which are peculiar to developing countries, can be overcome, higher certification levels can be achieved.

Research on how the database method can assist building performance diagnosis has become an important direction of current green building studies. Many research institutions have paid great attention to the building performance database, adopting new technologies to integrate indoor environmental quality and occupant satisfaction with building energy consumption data. This paper introduces and summarizes the data types, collection methods, and applications of current building performance databases, including those in the United States, the European Union, Japan, and Australia, as well as China. In view of the current problems of limited coverage, poor quality, and ineffective application of green buildings in China, this paper proposes a three-dimensional framework for green building performance databases. The collection and optimization methods of green building performance data are also discussed.

Building Performance

Green buildings are not entirely successful in achieving energy saving targets. One way of improving energy targets is to encourage occupants to adopt energy saving behaviour. To date, energy saving behaviour has been given less focus in improving green building performance than other energy saving initiatives, such as retrofitting buildings for green features. This study uses comparison case studies between green buildings and conventional buildings in New Zealand to better understand the energy saving behaviour of occupants. Questionnaires were distributed to occupants in green and conventional buildings to evaluate the extent of energy saving behaviour practiced and to identify potential strategies to encourage energy saving behaviour. The objective of this paper is to investigate the level of energy saving behaviour between green and conventional office buildings to see if people in green buildings perform better energy saving behaviour than people in conventional buildings in computer usage. The findings do show better energy saving behaviour from occupants in green buildings than occupants in conventional buildings. The paper shows why this is the case. The recommended strategies to encourage energy saving behaviour used by different buildings are also discussed. Strategies include raising education awareness on energy efficiency among the building occupants, energy saving commitments, and to have an active building manager assigned for energy related matters.
