What makes it eco-friendly

The Star Malaysia - Star2 - - Spaces -

HERE’S a quick run­down on what makes 99L, Jalan Tan­dok, en­vi­ron­men­tally friendly. > Max­imis­ing nat­u­ral day­light: The en­tire north-west fa­cade is clear glass while sky­lights above the straight-flight stairs within light up the south-east. More than 50% of the space is il­lu­mi­nated with nat­u­ral light that streams in through large glass open­ings and sky­lights. > Max­imis­ing nat­u­ral ven­ti­la­tion and ther­mal com­fort: Open­ings are crafted on all sides of the build­ing to fa­cil­i­tate cross ven­ti­la­tion. A stack ven­ti­la­tion ef­fect – also the chim­ney ef­fect, re­fer­ring to the air move­ment into and out of a struc­ture – is cre­ated us­ing stepped (ie, mul­ti­level) atri­ums with wide open­ings. All pub­lic and cir­cu­la­tion spa­ces are nat­u­rally ven­ti­lated, in­clud­ing lift lob­bies, es­cape stair­cases, toi­lets, and the sub-base­ment. > Reusing ex­ist­ing struc­ture: The pre­vi­ous four-storey struc­ture has been re­tained and in­cor­po­rated into the new build­ing, re­duc­ing the use of new build­ing ma­te­ri­als. The cafe­te­ria, ex­hi­bi­tion spa­ces, au­di­to­rium, stor­age space, train­ing room, and prayer rooms oc­cupy the old struc­ture. Also, the build­ing process used re­cy­cled con­tent, re­gional ma­te­ri­als, and ma­te­ri­als with low lev­els of harm­ful vo­latile or­ganic com­pounds. > Re­duc­ing heat gain and glare: Egg crate-like sun shad­ing de­vices and blinds in­stalled on the north­west fa­cade pre­vent glare and re­duce the amount of heat pen­e­trat­ing into the of­fice spa­ces. The shad­ing cuts down 60% of the so­lar ra­di­a­tion reach­ing the fa­cade glaz­ing.

Trees planted in break out spa­ces also help re­duce glare and shade the north-west fa­cade. Also, the cold air trapped dur­ing the night in the build­ing’s south-east-fac­ing con­crete wall is nat­u­rally re­leased in the morn­ing, help­ing to fur­ther cool down the build­ing.

> Sav­ing en­ergy: A high COP (co­ef­fi­cient of per­for­mance) value VRF (vari­able re­frig­er­ant flow) air-con­di­tion­ing sys­tem re­duces en­ergy con­sump­tion. Also, the build­ing au­to­ma­tion sys­tem has an en­ergy man­age­ment el­e­ment to im­prove en­ergy con­sump­tion and user-friend­li­ness by con­trol­ling gen­eral light­ing via photo and mo­tion sen­sors, en­ergy mon­i­tor­ing via dig­i­tal power me­tres, wa­ter us­age mon­i­tor­ing via dig­i­tal wa­ter me­tres, and ed­u­ca­tional dis­plays and analy­ses of the build­ing’s en­ergy per­for­mance.

> Us­ing re­new­able en­ergy: A 25kWp so­lar photo voltaic sys­tem is in­stalled on the roof ter­race.

> Sav­ing wa­ter: Wa­ter-ef­fi­cient fit­tings re­sult in 55% of wa­ter sav­ings. Also, all wa­ter re­quire­ments for flush­ing and ir­ri­ga­tion is fully met by a rain­wa­ter har­vest­ing sys­tem.

> Green sur­rounds: Trees planted in tubs within the build­ing on all floors help ab­sorb car­bon diox­ide and pro­duce oxy­gen. Ver­ti­cal green­ery and herb gar­dens are also in place for hu­man com­fort and con­sump­tion re­spec­tively.

> Waste man­age­ment: On-site com­post­ing al­lows build­ing users to be­come in­volved in and ed­u­cated about or­ganic waste pro­cess­ing and to con­trib­ute to the build­ing’s land­scape sus­tain­abil­ity. > Pro­mot­ing a green life­style: Hy­brid ve­hi­cle charg­ing sta­tions and bi­cy­cle racks out­side the build­ing en­cour­age greener modes of trans­porta­tion.
