Construction industry is one of the most of import industries in Malaysia. This is because building industry has direct or indirect influence with other 142 industries such as stuff processing, excavation, quarrying, machinery, manpower etc. It plays an of import function in national economic system as authorities ever pull strings the building industry to regulate the local economic system. As proven late, the Tenth Malaysia Plans with planned continuance of 5 old ages ( 2010-2015 ) are with some infrastructural installations earmarked for development to ease the state ‘s growing. One of the mega undertakings which the authorities had launched late is the Mass Rapid Transit ( MRT ) undertakings which worth a entire around RM36.6 billion covering a 20 kilometres radius around the Kuala Lumpur ‘s metropolis centre will transport two million passenger-trips per twenty-four hours when completed. Unfortunately, all the developments and buildings are the load to the natural ecosystem.
Sadly, building industry is good known for its “ 3Ds ” which is soiled, unsafe and demanding. In the term of dirty, big sum of wastes both chemical and non-chemical or solid wastes are produced during the production of edifices. Undeniably, landfill is limited and improper waste direction will do serious pollutions to the environment impacting the wellness of the locals. Furthermore, tremendous energy is wasted or loss through the envelope of the edifices. This increases the work load of the HVAC systems in the edifices every bit good as the demand for higher electricity ingestion. As the demand of electricity increased, the power workss will hold to bring forth more power to get by with the demand. In Malaysia, many of our power workss are still utilizing coal as a beginning of energy. Burning coal is harmful to the environment. Therefore, edifices with better envelope and more eco-friendly stuffs are needed to advance the sustainability of our female parent nature.
Research background
It can no longer be disputed that the resources of this Earth are finite, that its capacity to absorb our wastes is limited, that if we ( as a species ) want to last, we can non go on our pitiless development of the environment ( Szokolay, erectile dysfunction. 2008 ) . Mondazzi ( 2005 ) stated that the universe are recognizing these impacts through the loss of unfastened infinite, the deficit of H2O supplies, a turning dependance on energy and electricity from non-renewable resources, the decay of urban centres and attendant negative wellness impacts as suburbs continue to sprawl.
Global heating is an emerging issue of international challenges. The green edifice motion has its roots in the energy crisis of the 1970s and the originative attacks to salvaging energy that came with it, including the usage of active and inactive solar design and tighter edifice envelopes. The rapid growing population has caused the rate of development around the Earth. This has besides assisting the increase in the concentration of nursery gases. Buildings are some of the biggest energy consumers in the universe, accounting for one-quarter to tierce of all energy usage and a similar sum of nursery gas emanations ( Wen Hong 2007 ) . The planetary part from edifices towards energy ingestion, both residential and commercial, has steadily increased making figures between 20 % and 40 % in developed states, and has exceeded the other major sectors: industrial and transit ( LuisA Perez-Lombard 2007 ) . From 1971 to 2004, the universe ‘s entire concluding energy ingestion increased 87 per centum, with an one-year mean growing rate of 1.9 per centum ( Wen Hong 2007 ) . This statistic has brought the universe ‘s attending about the energy crisis. The intent of carry out this research is to better the apprehension in conserving energy in edifices.
Harmonizing to Sassi ( 2006 ) , population growing and the elevation of low life criterions will necessitate more resources, produce more waste and increase the impact on the natural environment. Buildings have lifespan of decennaries. Whatever edifices being built will ever impact the following coevalss. The grounds for clime alteration is turning more alarming each twelvemonth. The exceptionally hot summers such as those of 2003 and 2005 warned experts that the gait of this heating is faster than antecedently envisaged in their worst instance scenarios ( Sue, Davide and Fergus 2009 ) .
Problem Statement
The first job is the nature and usage of our bing engineering, which is mostly inefficient, outdated, and even in some instances obsolete. In the United States entirely, the edifice sector uses non-renewable and environmentally risky energy, emits 39 per centum of all energy-related C dioxide, lacks the ability to retain its generated energy long plenty to prolong indoor air quality degrees, and fails in recycling and pull offing H2O and waste ( Osman 2010 ) . Whereas in Malaysia, building industry is trusting on the inexpensive foreign labors workforce from other states such as Indonesia, Philippine and Vietnam. This causes the local companies to utilize foreign labors instead than high tech equipment which will maybe costs more.
Victor & A ; Julee ( 2004, p. 391 ) stated that others have argued that mere extenuation of environmental impacts is non sustainable, and that new attacks are preferred, for illustration based on care or even sweetening of ecosystem services. The scientific and technological cognition base for green edifice is besides limited, which is non surprising given the recent beginning of the subject ( Eric 2010 ) . Xiaoling, Liyin, Yuzhe, & A ; Guoyou ( 2011, p. 36 ) stated that fiscal cost is normally considered as the critical barriers for existent estate developers who are wavering whether to develop green existent estate undertaking or non.
The energy facets of environmental design and building have been more exhaustively researched than other facets, such as H2O preservation and reuse, reloading of groundwater, building overflow control, the usage of green edifice merchandises, and indoor environmental quality ( e.g. , daylighting, airing, low breathing stuffs, and indoor chemical and pollutant beginning control ) ( John 2010 ) . This may take to the uncertainnesss that the developers or proprietors need to take which they may necessitate to undergo some farther research to implement green construct on edifices.

Literature Review
Introduction
Western North California Green Building Council ( 2012 ) defines that green edifice, or sustainable design, is the pattern of increasing the efficiency with which edifices and their sites use energy, H2O, and stuffs, and cut downing edifice impacts on human wellness and the environment over the full life rhythm of the edifice. It is besides known as energy optimization. Surveies carried out by experts and professionals around the universe have indicated and proofed that edifices consumed the most energy compared to other sectors. Over the old ages, the energy ingestion has been increased drastically. Surveies have forecasted that energy ingestion will be increased by an alarming per centum. Harmonizing to Wen Hong, Chiang, Shapiro and Clifford ( 2007 ) , the universe ‘s concluding energy ingestion is expected to increase 1.5 times from 2004 to 2030. In the develop states, energy ingestion has surged enormously taking to planetary energy crisis. Those states are largely in South America, Asia, South-East Asia, and Middle-East. There are researches stated that edifices in China are one the most energy ingestion in the universe. Ksenia Chmutina ( 2010 ) stated that energy ingestion per edifice in China is 2-3 times higher than that of the developed states with similar climatic conditions and edifices are less comfy as a consequence of hapless thermic public presentation and excessively small insularity in most of China ‘s edifices. In recent old ages, Asia ( including South-East Asia ) has the highest economic growing in the universe but this comes with an inauspicious consequence. A research conducted by Wen Hong et Al ( 2007 ) shows that “ From 1971 to 2004, the universe ‘s entire concluding energy ingestion increased 87 per centum, with an one-year mean growing rate of 1.9 per centum. Around 43 per centum of the entire increase was attributable to Asia, where concluding energy ingestion increased 275 per centum, with an mean one-year rate of 4.1 per centum, more than twice every bit fast as the planetary norm. ”
Nowadays, most of the freshly constructed commercial edifices are equipped with centralized energy direction system or edifice mechanization system. This system controls everything from illuming to HVAC. They detect and extinguish waste, and enable the efficient usage electricity resources ( Iwayemi, Wan and Zhou, 2011 ) . With the aid of the energy direction system, corporations and owners are able to salvage their money by paying less for the electric measures. Energy direction system non merely optimises the energy use but it besides maintains the comfort of the residents. Energy direction system is an incorporate system which manages and controls multiple systems or elements in the edifices such as lifts, illuming, security system, HVAC system etc. Normally, energy direction system is made up of a hierarchy construction comprises of 3 degrees which are field degree, mechanization degree, direction degree. The lowest degree of the hierarchy is the field degree which consists of detectors and actuators. These detectors and actuators are fundamentally like ears, eyes and limbs of the system. They sense and present the information to the upper degree of hierarchy. The 2nd degree will be the mechanization degree which consists of direct digital accountants ( DDC ) . These accountants provide accurate designated reactions or command harmonizing to the edifice activities utilizing digital devices. The most upper degree of the hierarchy is the direction system degree which is centralized digital accountant. This degree is Acts of the Apostless as the encephalon of the whole system. It receives informations and information from the detectors and the actuators, so procedure it. After that, the system decides what actions to be taken to ease the energy efficient of the whole edifice. Furthermore, the system non merely able to command things but it besides shops the informations about the electricity ingestion of each unit or constituent as mention for the edifice proprietor. It besides detects the status of constituents and reminds the proprietor where care is needed for better energy efficiency.
In supplying better built environment, there are some benefits to the residents. A research conducted by Steemers and Manchanda ( 2009 ) shows that low energy design can accomplish some of the highest degrees of occupant satisfaction provides clear grounds that can promote edifice proprietors and interior decorators to be more confident of schemes and engineerings that are more energy efficient. Residents may be given to work more expeditiously and increase their productiveness in the pleasant environment. Excessive unreal lighting may do intense blaze and light as it will interrupt the ocular amenitiess and ensuing the residents ‘ weariness every bit good as concern. Therefore, keeping comfy light may assist to cut down the energy ingestion and maintaining the wellness of the residents.
One of the facets in edifices which can salvage a significant sum of energy is the unreal lighting. Artificial illuming which consume less energy or electricity might besides be given to cut down heat addition by the indoor environment. Therefore it helps to cut down the work load of air-conditioning to keep the indoor air temperature. About 40 per cent decrease in electricity ingestion was achieved after the deployment of CFLs which depicts that efficient house illuming with CFLs will conserves important electric energy for other intents ( Sule, Ajao and Ajimotokan and Garba, 2011 ) . The usage of compact fluorescent lamps ( CFLs ) that utilize up to 75 per cent less energy or electricity than candent visible radiation bulbs, can last up to ten times longer ( Sule et al. , 2011 ) . For the tantamount sum of brightness end product ( lms ) , the CFLs consumes 3 to 4 times less energy than candent lamps. CFLs besides last longer than candent visible radiation bulbs. The CFLs lifetime is at least 8 times longer than candent visible radiation bulbs. As a normal CFLs, it will last for six 1000s to fifteen thousand hours and candent visible radiation bulbs merely last for seven hundred 50 hours to one 1000s hours.
Another factor which will impact the energy ingestion of edifices will be the direction and administration. Some office edifices and hotels maintain indoor temperatures every bit low as 18 to 20 grades centigrade when the comfy temperature is about 24 grades centigrade ( Chan, 2004 ) . Many of the residents in those edifices are have oning jackets and utilizing USB warmers to maintain them warm. To keep such low indoor temperature, HVAC system will devour a batch of energy and needs frequent care every bit good. Basically, energy consumed to keep such low temperature will be merely wasted for nil. Many office edifices do non exchange off the HVAC during tiffin hr which mean that the HVAC is runing for the furniture but non residents. Other than HVAC, illuming inside the edifices besides takes up a big part in overall edifices ingestion. Many edifices are non designed to optimize the usage of natural lighting. Therefore, those edifices need a batch of unreal illuming to light the indoor environment and increase the electricity ingestion. In the other manus, big country of the unreal lighting are switched on for merely a few residents in the offices. This state of affairs is more or less similar to the HVAC system where the energy is consumed for nil.
Despite how small sum energy needed to run the HVAC system, it will non able to utilize the energy expeditiously if the edifice envelope is non decently insulated. Insufficient air-tight constructing envelope causes the warm or cool air may leak through. This will act upon the comfort of residents and greatly increases the work loads of HVAC system and therefore additions the ingestion of energy. High thermic transmission of the stuffs used for constructing envelope will do the heat transportations from the edifices to the environing causation terrible heat loss inside the edifices. A research conducted by VanBronkhorst, Persily and Emrnerich ( 2005 ) shows that infiltration histories for approximately 15 % of the heating burden in all office edifices countrywide, and a higher per centum be late constructed edifices. Therefore, the edifices must be insulated sufficiently and supply good air -tightness to forestall the escape of heat without detecting. However, the thermic insularity of edifices can be improved by utilizing several low thermic conduction stuffs such as aerated concrete blocks, fibreglass polyurethane and aluminum foil. The Windowss for most of the edifices in Malaysia are holding high thermic transmission and it is one of the major causes where the heat disperses through the Windowss. There are methods to be made to work out this job. The Windowss can be tinted and dual glazed to take down the thermic conduction of the Windowss.
Constructing orientation besides plays an of import function in energy efficient edifices. It affects the energy required for HVAC system. This is because solar radiation will heat up the edifices envelope quicker such as walls, doors and Windowss. This means that higher solar radiation causes the HVAC system to devour higher energy to keep the indoor air temperature. Building orientation is act like the natural shelter to forestall direct sunshine and solar radiation which will increase the heating rate of edifice envelope and causes over light to the indoor environment. Over light will impact the ocular comfort of the residents. As a consequence, residents may easy tire and endure from concern. Another ground associated with edifice orientation will be the airing effects which are the natural air currents or seasonal air currents.
The Energy Commission edifice or the ST Diamond edifice in Malaysia is one of the greenest edifices in the universe. The sides of the edifice are 25i‚° tilted from perpendicular to forestall direct sunshine and inordinate sunshine. The atilt and tinted glazing allows comfy glare free visible radiation to be reflected into the edifice from the landscape. Around 50 % of the full edifice country is illuminated by daytime. Furthermore, the edifice is sustainable as it is installed with 1930m2 of photovoltaic solar panels which will bring forth around 280,000 kWh yearly.
Issues and barriers on Green Buildings
In the context of green construct, there are some statements and issues associating to wellness and environment. Some stuffs used in lamps, such as quicksilver, are toxic to the environment and must be handled carefully. Large sums of quicksilver pose serious wellness hazards to neurological upsets and birth defects but with lesser sums of quicksilver, it will do the lamp to neglect, cut down the luminosity of lamp and shorten the lifetime of the lamp.
In planing and building the energy efficient edifices, building costs for the edifices will be much higher compared to the normal edifices. This is because energy efficient or low-energy edifices need better designs and building methods to increase and command the sum of natural illuming to light into the edifices. In the other manus, low-energy edifices need extra stuffs or better stuffs to be built in refering to cut down the thermic transmission of the edifices. Developers may non hold the capital to construct such energy efficient edifices. If they are able to make so, the lease will besides increased, therefore the costs will merely reassign to the residents or consumers. This will increase the fiscal load of the residents of the edifices.
Many people presume that the green edifice is necessarily costs more or less profitable comparison to normal edifice. Halliday ( 2008 ) stated that it is besides sensible to presume that the invention requited has a cost deduction of clip, planning, hazard and enhanced information demands, so inevitably pioneers will be penalise and their net income borders reduced when put in direct competition with non-eco-friendly edifice.
Developers and proprietors will ever see and look into the inside informations in implementing new green engineering. Uncertainties in new engineering may keep back the execution of the engineering. Duda ( 2009 ) stated that overall the largest barrier confronting the execution of green frontages is perceived fiscal hazard associated with event beyond the control of the proprietor or unexpected due to miss of illustrations and research. This means that we may necessitate more local green edifices as grounds to convert local developers or proprietors and besides as guideline for them.
Last, there is deficiency of policy and criterions for green edifice. Policy shapers frequently wait until something unwanted or ruinous happens before we implement controls and policy to decide the issue ( Duda, 2009 ) . In Malaysia, we are holding this job excessively. We have GBI to measure green constructing but we do n’t hold a specific policy and criterions to regulate the green edifice. There is Uniform Constructing By-Law ( UBBL ) for normal edifice building but there are no green constructing codifications or criterions in Malaysia. Without these criterions and policy, developers and proprietors are non bound to follow them.
Government Enterprises in Malaya
In Malaysia, authorities had foremost built the low-energy office edifice ( MECW, Putrajaya ) in 2001 with incorporate energy efficient design and showcased the edifice to exemplify the benefits of it to the populace. The MECW edifice saves RM600,000 per annum in electric measure. Normal edifices consume around 250 kWh/m2 every twelvemonth while MECW constructing merely consumes 114 kWh/m2 every twelvemonth. Malaysia ‘s authorities besides built the Energy Commission Building in 2005. This edifice has a alone diamond form which is intentionally designed for cut downing the thermic heat addition from sunshine. The sides of the edifice are 25 degree tilted from perpendicular to forestall inordinate solar radiation and sunlight radiance into the edifice. The atilt and tinted glazing allows comfy glare free visible radiation to be reflected into the edifice from the environing landscape.
The governments in Malaysia are suggesting ordinances and policies on the attempt of energy efficient in Malaysia ‘s building industry to better the surrounding environment and cut down the demand growing rate of electricity. The ordinances and policies will non merely profit the environment but the state economic sciences as good. With the decreased demand growing rate of electricity, the authorities does non necessitate to construct more power Stationss and facing clip restraints on the development of sustainable energy.
Planing Green Building
Having a green edifice, it must be good designed in term of sustainability and environmentally friendly. Planing a green edifice is non an easy undertaking. It need to see the elements and constituents which will assist to cut down the C footmark and energy ingestion such stuffs used, the life rhythm of the edifice and the natural lighting. These elements and constituents are the cardinal ingredients for a green and sustainable edifice. By and large, the green edifice interior decorators must see the following 3 rules: –
Connectivity: design to reenforce the relationship between the undertaking, the site, the community, and the ecology. Make minimum alterations to the natural operation. Reinforce and steward those natural features specific to the topographic point ( Williams, 2007 ) .
Autochthonal: design with and for what has been resident and sustainable on the site for centuries ( Williams, 2007 ) .
Long life, loose tantrum: design for future coevalss while reflecting past coevalss ( Williams, 2007 ) .
Materials used for green edifice must be of low C footmark during its fabrication procedure and throughout its whole life rhythm. Interior designers should take into consideration that the sizes and forms of the stuffs or constituents to be used. This is because the film editing and operations on the site may impact the wastages of the stuffs. As the wastages reduced, the building costs besides reduced and net incomes will increase.
With the current computing machine patterning engineering, Building Information Modelling or BIM, Autodesk ‘s Ecotect and Green Building Studio are now deriving popularity around the Earth to assist the interior decorators in C appraisal of the edifices. This would advance the green construct designs to be a more systematically run into the mark of the proprietors without over-design or under-design.
It is recommended to deviate the edifices into constituents and faculties, so fabricate it offsite. This is besides known as prefabrication. Presently in Malaysia, fabrication of edifices ‘ constituents offsite is acquiring more and more popular, particularly in metropolis country such as Kuala Lumpur and Penang. This is because bringing of concrete from metropoliss ‘ fringe has a clip restriction. If the concrete trucks stuck in a traffic jam more than the allowable continuance, the concrete will indurate. Furthermore, prefabrication can better quality, cut down wastage and cut down building costs. Components and faculties manufactured in mills have high consistence in size and ease the quality look intoing procedure. Insistent constituents and faculties with high consistence of size merely intend that the mills will set up the film editings or molding and apportion their resources more efficaciously, so that the wastage is minimum. In add-on, prefabrication besides reduces the building activities and clip on undertaking site. With shorter clip on site, it besides reduces the exposure of uncomplete plants to the conditions. This may really assist to decelerate down the corrosions of constructing stuffs such as steel bars and pigment. Hence, it reduces the chance of rejected plants and redo of plants which will increase the costs of building and wastages.
Why edifices need to be ‘green ‘ ?
In economic point of position, energy efficiency is defined as the ability to bring forth the same economic end product with less energy input ( The Aspen Institute, 2009 ) . In concurrence, it besides conserves the environment by cut downing the C footmark caused by conventional energy production. There are some undeniable benefits which the green edifices can supply, which are: –
Enhance biodiversity – non use stuffs form threatened species or environments and better natural home grounds where possible through appropriate planting and H2O usage ( Halliday, 2008 ) .
Reduce wastages – non devour a disproportional sum of resources, including money and land during stuff sourcing, building, usage of usage or disposal ; non do unneeded waste of energy, H2O or stuffs due to short life, hapless design, inefficiency, or less than ideal building and fabrication processs. Buildings have to be low-cost, manageable and maintainable in usage ( Halliday, 2008 ) .
Minimise pollution – create minimal dependance on polluting merchandises and stuffs, direction patterns, energy, power and signifiers of conveyance ( Halliday, 2008 ) .
Create healthy environments – enhance life, leisure and work environments ; and non jeopardize the wellness of the builders or residents, or any other parties, through exposure to pollutants, the usage of toxic stuffs or supplying host environments to harmful beings ( Halliday, 2008 ) .
Reduce runing costs – as the edifice is good design in term of edifice stringency and usage of natural lighting, it would really assist to cut down the sum of the electric measures.
Green edifices non merely conveying benefits to the environment but besides the fiscal net incomes every bit good as the wellness and comfort of the residents. In the context of oil monetary value hike, states and corporations should be more concern about their fiscal and economical profitableness, for case it besides slows down the electricity demand growing and the planetary heating consequence.

Factors which drive the Green Building
Hike of energy monetary value
In these recent old ages, planetary oil monetary value is volatile. As the universe ‘s demand on energy is keep increasing, the supply will go more sacred and the monetary values to bring forth energy will besides travel up. This is because the energy industry will necessitate more resources, bigger workss and better equipment to bring forth more power. In Malaysia, energy coevals is still trusting a batch on non-renewable resources which are fossil fuel, natural gas, coal, and crude oil. These resources are subjected to planetary economic system effects which mean the monetary values fluctuate as the planetary monetary values. Undeniably, the electricity costs in most states besides fluctuate over clip as these resources ‘ monetary values.

Higher market value and cost effectual
There are Numberss of surveies were carried out sing the value of green edifices. Czech Green Building Council ( CZGBC, 2012 ) stated that commercial edifice with environmental enfranchisement in the UK is sold at approximately 38 % higher monetary value than a comparable non-sustainable edifice. Other surveies from Germany and Switzerland show that a house or flat in a high energy criterion or with enfranchisement can be sold in the market by up to 17 % higher monetary value than a conventional undertaking ( CZGBC, 2012 ) .
In concurrence, United State Green Building Council ( USBGC, 2011 ) besides stated that constructing sale monetary values for energy efficient edifices are every bit much as 10 % higher per square pes than conventional edifices. An upfront investing of 2 % in green edifice design, on norm, consequences in life rhythm nest eggs of 20 % of the entire building costs – more than ten times the initial investing ( USBGC, 2011 ) .
Furthermore, renters who choose to lease the green commercial edifices have their ain grounds. The undermentioned figure shows the grounds and statistics.

Legislative inducements
In many states, attempts have been made by the authoritiess through revenue enhancement inducements to advance the development and usage of green engineering. Malaysia is non excluded every bit good. In the 2010 Budget Speech of Malaysia, Prime Minister, Mohammad Najib ( 2009 ) stated that the Government will bear 2 % of the entire involvement rate and supply a warrant of 60 % on the funding sum, with the staying 40 % by banking establishments.
In the twelvemonth 2009, the Green Building Index ( GBI ) has established to advance the building of green edifices. In the 2010 Budget address, Prime Minister, Mohammad Najib ( 2009 ) stated that edifices proprietors obtaining GBI Certificates from 24 October 2009 until 31 December 2014 be given income revenue enhancement freedom equivalent to the capital outgo in obtaining such Certificates and purchasers buying edifices with GBI Certificates from developers be given stamp responsibility freedom on instruments of transportation of ownerships. This freedom has included the gross revenues and purchases ( S & A ; P ) understandings.
