Economic feasibility of green office building: combining life cycle cost analysis and cost–benefit evaluation

ABSTRACT Construction practitioners have adopted the green building (GB) concept to restore environmental damage caused by the built environment over the last decade. However, there is inconclusive debate regarding GB savings’ potential to recover the cost of construction, maintenance, and renewals. This paper evaluates the feasibility of green-certified office buildings in Indonesia by comparing the life cycle cost and presents the cost–benefit ratio. Data were obtained from primary data and combined with reliable secondary sources for analysis. The result shows that GB requires an additional cost of 9.22% but offers energy and water savings over the building’s life cycle accounted for 58.65%. Research has shown that GB adoption reduces the cost per square metre by 41.74% over the traditional one. The cost–benefit ratio of energy, water, and carbon emissions was 2.35 and thus, justified the increased costs of investment, maintenance, and renewals of GB. This research’s findings can assist policymakers, practitioners, developers, and other interested parties in the construction sector in bringing forward regulatory changes, collaboration initiatives, capital investment, or other decision-making support.

The Direction of Developing Green Building Criteria in Indonesia

Until 2020, one province and two cities in Indonesia have local regulations governing green buildings’ implementation. Besides, there is also a ministerial regulation governing green building implementation, which serves as the primary reference for various cities or provinces that do not have local green buildings regulations. Three of the four laws are more than four years old. The implementation of these regulations has resulted in various achievements and findings and multiple obstacles. It is time to review these criteria so that the green building concept’s performance is broader and more weighty. This study aims to review these regulations’ requirements, particularly the requirements related to passive strategies, and propose further development directions. We were researching by dissecting the criteria contained in the rules, analyzing the potential impacts generated, and then comparing them with the opinions of building stakeholders. In the future, the green building regulation criteria need to prioritize measures that can significantly impact the environment and energy, and people as the three essential factors of the green building concept.

Study the application of “green building” on the aspect of the shape and facade LP2M UNNES building

In designing a building, the shape and facade have a very important role. Green building is a high-performance building designed to be responsive to the environment, economically sufficient profit, and as a healthy place to live and work (environmentally responsible, economically profitable, and healthy places to live and work). The concept of ‘green’ is not just a current trend, but must be treated as a basic principle when we start designing buildings. The characteristics that emerge from the design of the shape and facade of a building will form the image of the building itself. To find out the explanation of the concept of the shape and facade of a building, in this research qualitative research with content analysis method is used, through a study of the main building with a case study of the building of LP2M UNNES Sekaran Gunungpati Campus by applying descriptive analysis content. From the analysis study, it will be known that the building has undergone a transformation in the form of addition and subtraction. In designing environmentally friendly buildings is actually a process. The goal is not to make a perfect building, but rather to create a better building. One of the advantages gained in applying the Green Building concept is efficiency. In terms of the facade of the LP2M UNNES building, it appears that in the processing of the embodiment of the shape of the building, of course it is also influenced by material elements, color, proportion, rhythm, and texture. From these studies it is expected that the facade elements of the appearance of a building will show the identity and character of the building.

Analysis of photovoltaic-green roofs in OSTIM industrial zone

In the current century, climate change, air pollution, and the depletion of energy resources are big threats to our society, especially in urban areas. It is an inevitable fact that we need to develop the green building concept and produce innovative solutions in our quest to design structures that are compatible with nature, sustainable, environmentally friendly, aesthetic and use natural resources efficiently. Roofs are the most efficient and promising building surfaces for the combination of photovoltaic panel applications and green roofs considering their locations and inclination angles. This research focuses on how carbon emission can be reduced via both green roofs and solar energy while producing electricity in OSTIM, one of Turkey's most prominent industrial zones located in the capital. The long-term detailed analysis of photovoltaic-green roof application in terms of economics and carbon emission is discussed. Although the rooftop option of a combination of solar panels and a green roof design costs higher than a standard photovoltaic system, it opens up new prospects for urban lighting in smart cities with exciting aesthetic effects. This combination of two sustainable features can become a model of green technology and opens up a wide range of research applications.

Research on application and thermal performance of raw earth material in building envelope

Mainstream green has recently swept the construction industry throughout the world. Building envelope and material are two important aspects of green building evaluation. As the growing development of new green building concept “human-orientation design”, raw earth, as a natural, locally sourced, minimally processed, and recyclable material that is very different from concrete, becomes one of the most attractive options. Most architects pay attention to the aesthetic design of the raw earth wall, while other researchers like civil engineers focus on the physical properties of raw earth material itself. Few studies discussed the effect of the raw earth wall in building a thermal environment. This paper firstly conducts a parametric study on the thermal performance of raw earth wall with the consideration of thermophysical properties of materials, application of thermal insulation layer in the wall, and design parameters, i.e. thickness, of each layer of the wall. A naturally ventilated public building in Shanghai is then simulated to discuss the feasibility and the most optimum strategy of raw earth wall applications as building envelope in the sub-tropical high-density cities. Based on comprehensive data analysis, four findings are identified: (1) Compared with common building materials like concrete, raw earth materials have significant advantages in two thermophysical parameters - thermal transmittance and thermal effusivity which directly influence the indoor air temperature; (2) Thickness and structure of both raw earth layer and insulation layer are two important design parameters to meet the requirements of the indoor thermal environment; (3) Raw earth wall performs better than the standardized “Green Wall” based on local green building standards; (4) In terms of thermal performance, “Raw Earth Wall with External Insulation” is more suitable in subtropics. However, “Raw Earth Wall with Sandwich Insulation” is more recommended if pursuing the beauty of raw earth materials, because the thermal performances of “Raw Earth Wall with Sandwich Insulation” and Raw Earth Wall with External Insulation” are almost the same in summer, and very close in winter.

The Effect of Palm Oil Fuel Clinker Powder and Cockleshell Powder as Cement Replacement on Durability Properties of the Concrete Mortar

The concepts of eco-friendly building are getting more attention today. The standard materials of concrete that used such as cement and aggregate are not totally environmentally friendly. Thus, many materials from natural sources can be an alternative to the realization of the green building concept. As a result, many researchers have devoted their attention towards identifying eco-friendlier substitutions to be used in concrete. This study was conducted to investigate the efficiency of two different types of waste materials which are palm oil clinker (POC) and cockle shell (CS) as partial replacement of cement on durability aspects. The POC and CS materials were ground to achieve a small particle size to fit with the concrete mix as cement replacement. The replacement of cement was at different levels (10% and 20%). Six mix proportions were made with different percentage of palm oil clinker powder POCP and cockle shell powder CSP. The specimens were cured by immersing in water for 7 and 28 days. The tests that were conducted were acid resistance test and water absorption test. Therefore, the experiment result showed that the POC had a negative impact to the concrete in both tests while the CSP proved it is resistance to acid.

Building Reconstruction of Historical and Cultural Protection Area Based on Green Technology

With the continuous intensification of urban expansion, the transformation and utilization of existing building resources has gradually attracted attention from all walks of life. The Lifen building is the epitome of Wuhan's residential culture for nearly a century. After the baptism of time, the use function and structural safety of the Lifen building can no longer meet people's living needs today. Therefore, further research is needed on how to combine the protection and renovation of the Lifen building. This article takes Kunhouli, Jiang’an District, Wuhan as an example. Through field research and semi-open interviews with local residents, it is found that the current Kunhouli has poor thermal comfort, traffic congestion, outdated infrastructure, and lack of public space. And poor construction quality. According to the regional and cultural characteristics of Lifen, combined with the concept of green building and green analysis software, it is updated and transformed to promote the protection of Lifen while improving the living environment of Lifen, providing reference for the development of Wuhan Lifen's building renovation.

Militating Factors Against the Practice of Green Building as a New Paradigm in Construction Projects

The green construction techniques is a relatively new building philosophy with an unprecedented opportunity to in the global carbon reduction targets as well as pushing the application of more environmentally friendly materials, strategies of saving resources, lower waste production, and the improvement of indoor environmental quality, among others. However, this technique is faced with many pullbacks especially in Nigeria. Hence, the paper sought to assess the militating factors against the practice of green building as a new paradigm in construction projects. The research implored the combination of a quantitative and qualitative approach. The focus was on the buildings within FUTO with more concentration of new buildings constructed between 2012 and 2017. The primary data was obtained through observations and by administering questionnaires to lecturers familiar with the design, construction and management of the buildings. For quantitative method, parameters that define green construction with a range of variables from minimal to complete incorporation of the elements, determined the degree of conformity. The result from the research revealed that, to a ‘Great extent’, lack of enforcement and limited research were the greatest militating factor facing practitioners in the adoption of green building concept with these two factors having relative importance index (RII) of 0.81 and 0.79 respectively. Lack of awareness (0.63) was a moderate challenge practitioners faced in the adoption of the concepts. The research recommends that suitable policy, structure and consequence be put in place to enforce green building concept as well as opportunity for continuous research in this field.

Research on Value Stream Analysis of Prefabricated Building Based on SVN

With the adjustment of the national industrial structure, the transformation of the production mode of the construction industry and the advocacy of the concept of green and energy-saving building, prefabricated building will become the next trend of the construction industry. However, prefabricated building has not been popularized in China's construction industry, which may attribute to the participating parties have not realized the value-added effect that brought by the application of prefabricated building. Therefore, it is necessary to analyze the value gained by all parties in the application of prefabricated building from a global and systematic perspective. Based on the theory of Value and Stakeholders Value Network (SVN) methods, this paper may build a network with value – information – coordination of the stakeholders in a prefabricated building project, and make a comprehensive evaluation on the value acquisition ability and the uncertain risks of key stakeholders in a prefabricated building projects, which may provide a new perspective for the implementation and decision-making of prefabricated building projects.
