The Challenges In Delivering Green Building Projects In Malaysia
- a.Green Buildings
Building activities like transposition of raw materials, processing, extraction, operation, construction, design and demolition have adverse effect on the ecosystem and environment together. Excessive emission of wastes, resource usage and the greenhouse gas emission has serious impact on the all kind of living creatures. In order to avoid the adverse effect from these building activities Green Building projects has been proposed (Ali et al. 2018). These construction building projects have minimum environmental footprints which are proposed as a developmental model in the construction and building sector. Building projects from the Green Building Projects has been designed based on the principles of the sustainable construction.
The construction products from the Green Building Projects are generally created using clean, resource efficient measures and the best practices. The adverse impact from the building activities are reduced through extracting the raw materials from the demolition and making disposal of all of its residue components from the building activities. There are many other factors are associated in case of delivering the successful Green building projects. Owner Commitment is one of the important activities in the construction project which is strictly regulated by the Green Building projects Team member. Overall aim of the designed projects and information concerning the designed mission has been delivered to the Owners of the construction project from time to time (Bohari et al. 2017).
- b.Issues and Challenges for delivering projects in Green Buildings
In this research paper a typical analysis has been done on examining the new associated activities in construction projects. In the Real estate development process the associated transaction cost for the Green building projects has been analysed.
Some of the other challenges and issues faced by the Green Building Stakeholders are under the supervision, maintenance, design, public awareness and perception, government reinforcement, the participation of the stakeholders. The existing guidelines in the Green building project the project manager's role is quite unclear. It has been observed during the research study that, construction cost is one of the major issues rises while delivering the Green building projects in Malaysia. Because of the higher construction cost, most of the builders in Malaysia are willing to go for traditional building procedures rather selecting the Green Building procedures.
- Issue 1: Lack of national guidelines
Lack of national guidelines has been seen from the end of the Malaysian government to implement the Green building projects and its implementation in the respective states. There is difficulty exists in justifying the execution and implementation of the Green Building projects in Malaysia from the end of supervision, maintenance and design. Existing code of practice and the guidelines on renewable energy and on Energy efficiency in order to achieve the emission of low carbon building has not covered in the Malaysia construction regulations. Green Building projects implementation and its execution has not been covered in the MS1525 and in the publication of EE buildings guidelines. Not covering industries rating is also another existing issue factor in the Green building. As per the comment of Chan et al. (2018), the rating tools like pH JKR, Green pass and Green building index does not cover the procedures and methods of the Green building projects. Including these factors these rating tools also does not cover the projects supervision, designing stage and its maintenance. This directly impacts on the owner’s behavior in order to go for Green building projects. According to Darko et al. (2017), United States Environmental protection Agency, sustainable building are also referred to the Green building which are resource efficient and environmentally responsible throughout the constructed buildings life cycle: from construction, design, maintenance, operation, demolition and renovation.
- Issue 2: High cost requirement for project implementation
High initial project cost along with the change management during the construction work is some of the possible key challenges faced by the construction management along with its owners. Delivering Green Building projects in Malaysia are quite different compared to the conventional building in case of accumulating the hidden cost. Cost is an major existing challenging issues in the Green building projects. Though the efficiency and the environmental friendly is one of the attractive features of the Green building projects, however most of the construction project owners are not showing any willingness to the projects in Malaysia. The new activities involved are uncertainties in making deals with the stakeholders who are not et al appreciating the hidden costs of occurrence. Above is the only reason because of which many agencies and the stakeholders prefer to implement the conventional projects compared to the Green building projects. Stakeholders and the agencies are less aware about the Return of Investment from the Green buildings in Malaysia. Savings of water and the electrical consumption is also considered as the part of the ROI from the end of Green building to the stakeholders and users (GhaffarianHoseini et al. 2017).
- Issue 3: Public Awareness and perception
It has been observed that awareness among the people regarding the implementation of the Green Building projects are still at the minimum stage. In case of New Zealand creating awareness regarding the Green build projects will create the demand and industry drive for the eco friendly buildings. As per the comment of Olanipekun, Xia & Nguyen (2017), this will result the increase demand of the sustainable buildings. Reuse, recycling and reduce is the promoted slogan from the end of non government and government agencies. Energy saving creates the public awareness and most of the people might get adopt the latest growing technology in the construction work. Raj (2016), has pointed out that public should be educated and exposed towards the importance of the implementation of Green Buildings in the Malaysia.
- Issue 4: Participation of the stakeholders
As per the comment of Rinkesh (2018), the participation of the stakeholders and the business owners is one of the important tasks in construction projects of Green building projects. Participation of the stakeholders helps in identifying the green building design projects sustainability with the constructed buildings function, operation and usages. Participation of Stakeholders affects the contribution towards perceived legitimacy towards the management decision.
- Issue 5: Change management in the project management
As stated by Raj (2018), changing the conventional method of construction of building to the Green building methods is one of the accountable challenges faced by the constructors. Many of the project teams and the project managers face difficulties to deal and adopt the changes in the meanwhile of development. The whole of the project's success only depends on the acceptance of the involved people in the project work especially managers support is utmost seeking for project success.
- Issue 6: Government enforcement
Enforcement form the end of government leads to the success of the Green Building projects in Malaysia. Keeping an eye on the environmental issues like global warming and ozone layer depletion it is important for respective countries government to reinforce and enforce the activities which lead to resolving the environmental issues. The role of the Malaysian government to make effective programs to enhance the construction projects using the Green building projects. Builder incentive must be provided to the buildings which are created using the Green building projects. The cost of construction must be effective and government support must be provided to the individuals in the construction work.

- c.Embracing the Green Building in Malaysia
Malaysia is embracing the concept of green building which is driven by the cost saving (cleanmalaysia.com, 2018). Greening building has become one of the most affordable and popular in the modern days due to its wider practice. As per the Green Building Index, a building will come under the criteria of a green building if it achieves the six key criteria namely innovation, efficiency, energy, sustainable site planning, indoor environmental quality, management of the resources and available materials. The market size of the engineering and the building construction has been planned to grow at multiple annual growth rates. It has been also researched that annual growth rate of buildings raises 6% to reach the US$7.34 billion by the end of 2020.
As per the report of Green technology by the end of 2020, Malaysia has aimed to delivery 70% Of the total market to be accounted for Green construction services, building solutions and its management and green materials which going to promote environmental stability.
The future of construction buildings and the involved engineering market has expected to be propelled with the Malaysian proper reliefs, tax incentive structure, elimination and reduction of tariffs while importing the green building materials, transfer and technology shift will be seen. Using the technology Malaysia has been planned to bring the greater application of renewable energy resources in construction era. Green Township is one of the proposed destined areas of the Greenhouse buildings. It also been stated that the investors will provide the best possible solution for the existing global issues of pollution and rise of carbon dioxide due to construction work. Malaysia has been planned to strong and clear mechanism to promote greening in the older buildings.
Economic transformation programme are the underlying mission which boost the nation's economic growth in the respective country. This brings supportive changes in the demographic like migration, annual population growth and the urbanisation rises in the Malaysia. As per the comment of Rinkesh (2018), this result of dynamism effects on the rise of buildings, commercial zones and the business. The Economic transformation programme has been expected to foster the rapid growth in the healthcare and in tourism sector. Apart from the rise of the demands of agro-tourism and the eco-tourism also rises in Malaysia. Green building Index tool has been proposed to create socio-economic awareness in Malaysia.
In the year of 2010 Malaysia budget announcement, the certificate of GBI has been introduced to relieve the tax included in construction work. GBI tax incentives the exemption of stamp duty of the amount US$467 million fundings are under the National Green technology. The building construction market in Malaysia is considered as one of the highly competitive markets in global. It has been estimated that 25-30% of total Malaysian buildings are constructed by the green elements. In the year of 2020, the estimated market size is of green elements rise by the US $1.056 billion to the US$1.276 for engineering and well as for the Green Building construction.
- d. The Construction process involved in Green Building materials
The building process of the Green Building projects has been refined over a period of time. The projects construction phase differs from one another. Gradually the projects proceed further to major phases. There are basically two phases a Green building projects construction work undergoes are listed below.
Bidding phase of the construction work consists of pre-design, conceptual design, design development and documentation of the detailed design work. In the construction phase whole of the maintenance and the operation work of the constructed building will be considered. In the below mentioned headings a brief discussion on each of the undergoing process has been elaborated.
d1. Bidding Phase
According to GhaffarianHoseini et al. (2017), the construction documents have been designed by the professional before proceeding to the construction work. This helps the professionals to bid the construction projects by the published advertisements. In this way, the public projects will be the handover of the construction work. During the stage, the bidders solicit the bid for the construction work. Economical bidding process helps the contractor's to find out the right owner for the projects. In Malaysia public projects it is utmost important to educate the generals of involved bidders like contractor's, subcontractor's, suppliers and the manufacturers of the GBM system. It has been observed that the most of the bidders are involved in the pre-bid conference. In this the awareness on the specification of the Green building construction projects will be explained.
Local climate will be studied for understanding the allocated space for designed construction project work.
The activities define the massing, building orientation, window size, program layout and the facade shading.
Optimisation of each of the available space for daylighting, natural ventilation will be done.
Documentation and detailed design:
Precise construction work will be delivered to the hand of the client's by the MEP engineers.
d2. Construction Phase
In this phase, the engineers have been ensured that the designed construction team will be going to build effectively the project based on the performance and design specification. The Green building project team workers will be fully engaged towards drawing the connections, constructions and the available systems which will be going to build (theborneopost.com, 2018). This phase is drawn by the building contractors.
Once the Green building has been built the occupancy of the building commissioned. In order to handover the project to the owner the building gets ensured by the quality engineers that all of the systems are working properly. Confirmation of the thermal comfort and monitoring continual energy usages is checked once the occupants have moved on to the building.
In case of any error detected or fault in the equipments will be controlled in earlier manner. Validation of the building performance can be done through controlling the settings flaws. Ongoing maintenance and monitoring is done by the working professionals.
- e. Risk management for the GBM
The used building material in the construction work of Green building projects are made up of in good environment. It has been observed that most of the material sued in the GBM is very new in the market and also does not having any experiential credentials to claim the support for the used materials. As per the comment of GhaffarianHoseini et al. (2017), field testing leads to add newness to the Green Buildings. In the Greenwashing the existing prospective risks are identified. The owner of the building has pledged to state and select the untried products for the project work. Beta testing has been done on the individual buildings and this confirmation has been handover to the respective owner. Different response has been drawn from the different involved members in the risk potentials of the project work. Reuse of the green materials can be done by the individual's.
- f. Gap Analysis
There is a gap has been identified in the literature of Green building projects in Malaysia. There is lack of government's contribution towards implementing the Green building projects, distribution and promotion. In order to avoid the existing gap of communication among the government bodies and the owners the Malaysian government must start on allocating the budget for enhancing the demand of Green building project implementation (cleanmalaysia.com, 2018). This helps in mitigating the gap of high cost impact on implementing the Green building projects.
