    Guidelines to Practice Energy

    Efficiency in CKE Design

    1.0 Introduction

    Energy Efficiency (EE) in the JKR context means the efficient utilization of energyduring the operational lifespan of a building here the comfort of its occupants isnot compromised nor sacrificed! "nitially EE can be achie#ed by isely ta$ing#arious energy sa#ing measures during the design stage of the building! "npro%ects designed by JKR& energy in buildings is associated mainly ith electricity!

    'ften this is mista$enly ta$en to imply that EE is the sole responsibility ofelectrical engineers! "n reality& anything that leads to the e#entual enduse ofelectricity is related to EE in buildings!

    2.0 Integrated Design Approach

    "ntegrated building design is a process of design in hich multiple disciplines andseemingly unrelated aspects of design are integrated in a manner that permitssynergistic benefits to be realized! he goal is to achie#e high performance andmultiple benefits at a loer cost than the total for all the components combined!his process often includes integrating green design strategies into con#entionaldesign criteria for building form& function& performance and cost!

    o achie#e EE in JKR constructed buildings& it can be carried out by applying bothpassi#e and acti#e design strategies!

    *assi#e design strategies includes adopting design measures such as buildingorientation and shape& site planning& selection of building en#elope all and roofmaterials ith lo thermal mass conducti#ity& building shading design& indotype and design& type of glazing& daylight har#esting strategy& using natural#entilation and good landscaping design!

    +hile acti#e design strategies refers to selecting energy efficiency e,uipment&

    utilities systems& control system and strategy that result in direct reduction in thebuilding energy running costs! his includes using high efficiency -./C system&such as using .ariable /ir .olume (./.) or chilled beam air conditiontechnologies0 using high efficiency motors& pumps and fans& .ariable peed2ri#ers (.2s) ith motor dri#ing pumps and fans ith #ariable loads0 use of highefficient lighting system and occupancy sensor and use of effecti#e control systemsuch as 3uilding /utomation ystem (3/)!

    "n Caangan Ke%uruteraan Ele$tri$ e are focused on acti#e design strategy oneof hich is includes Electric 4ighting 2esign! his ill be focused in this guideline!

    3.1.2 Electronic $allast for %luorescent ighting

    /lthough electronic ballast sa#es substantial amount of energy& it is not idelyused to replace the relati#ely energyinefficient standard electromagnetic ballastbecause of its higher cost

    Electronic ballast gi#es significant energy sa#ings ith fluorescent lighting&typically reducing poer consumption by around 69:! Electronic ballast aredesigned to last 17 to 19 years lifetime ith long burning times and lo sitchingfre,uencies! hey are more compact and ;7: lighter eight than electromagneticballasts!

    Aood lighting practice for or$place is more than %ust pro#iding good tas$#isibility! "t is essential that tas$s are performed easily and in comfort! hus& thelighting must satisfy the ,uantitati#e and ,ualitati#e aspects demanded by theen#ironment! "n general lighting is to ensure?

    iii! #isual safety& to see oneBs ay around the detect hazards!

    Colour /ppearance

    he #ariation in the amount of colours ithin a light mixture affects theappearance of the light in terms of its relati#e GarmnessB or GcoolnessB! odescribe this GarmnessB and GcoolnessB of the colour of the light sources& the termGcolour temperatureB is used!

    Colour emperature or Correlated Colour emperature (CC) due to itstheoretical basis in the study of Gblac$ bodyB radiation should apply only to sourceith a continuous spectrum (such as incandescent lamps and natural light)!-oe#er& for light sources ith non continuous spectral distribution (such asfluorescent lamps here the spectrum consists of pea$s of energy)& CC is usedmainly on an empirical sense (i!e! in a #ery Gnear approximateB sense)!

    Colour Rendering

    / more common method of characterizing light sources by its colour is the ColourRendering "ndex (CR")! he CR" compares the spectral energy content of a lightsource to that of a standard reference source ith full spectrum! he CR" #alue isthe numerical #alue and is 177 for fullspectrum natural hitelight! "ncandescentlights are considered nearly hite and ha#e CR" close to 177! =ost lights ha#eCR" typically in the range of 67 87!

    he CR" model is not a perfect model and should only be used to compare lightsource ith the same colour temperature! or example& (about) ;777K daylightfluorescent and clear mercury has CR" of D; and 66 respecti#ely! he daylight

    fluorescent ill therefore render colours better than clear mercury! he differencebeteen a @577K tungsten halogen ith CR" >> and an ordinary 6877Kincandescent ith CR" >6 can usually also be differentiated by most obser#ers!2espite the small difference in CR" #alues& the tungsten halogen ill rendercolours more #i#idly compared to the ordinary incandescent!

    he cost premium for -E= is about 97 to 197 percent abo#e the cost of ana#erage motor! /n -E= comes ith higher capital cost but there ill be asignificant amount of energy sa#ings during its lifespan! he =alaysianAo#ernment has made it e#en more attracti#e to buy -E=s by offering?

    Exemption on import duty and sales tax& and

    "n#estment tax alloance for energy efficient e,uipment

    'n a#erage& the initial purchase cost of a motor only ma$es up 6: of the total

    cost of onership! he total electricity consumed to operate the motor o#er itslifetime of 19 years ma$es up >D: of its total lost!

    9!6!6 a#ings in Running Cost

    he energy costs of a motor can be ,uite high o#er its lifetime! he longer theoperating hours& the higher energy costs! herefore& the lifetime cost calculationsshould be performed to determine hether repair or replacement of an existingstandard motor ith a high efficient motor is more economical!

    a) Running emperature -igh efficiency motors operate ithin the same Class 3temperature limits as standard motors but ill not dissipate as much heat!

    b) =aximum poer capability 3efore changing to a smaller& loer rated motor& it isimportant to chec$ that no load ill arise hich ill exceed this ne rating!
