Em­bod­i­ment of fu­tur­is­tic spirit

Down to Earth - - LIFESTYLE -

THE CAM­PUS of this re­search, de­vel­op­ment and man­u­fac­tur­ing com­pany rep­re­sents the kind of 21st cen­tury ar­chi­tec­ture that pro­vides com­fort while en­sur­ing min­i­mal im­pact on the environment. The build­ing is de­signed with the quin­tes­sen­tial glass look as­pired by a typ­i­cal cor­po­rate en­tity. But glass traps heat. The ar­chi­tect cir­cum­vents this prob­lem by us­ing sheets of glass that are of proper size and shade, and has fit­ted them at places where they of­fer the max­i­mum ben­e­fit.

The build­ing avoids glaz­ing on east and west di­rec­tions, which are as­so­ci­ated with un­con­trol­lable so­lar ra­di­a­tions, whereas al­most 60 per cent of the façades fac­ing north and south are cov­ered with glass. Cur­tain wall glaz­ing has been done only in lob­bies that do not re­ceive di­rect sun­light. Heat ingress has been fur­ther con­trolled by plac­ing shad­ing de­vices hor­i­zon­tally in the south and ver­ti­cally in the north. These en­sure that the build­ing re­ceives good day­light with min­i­mal over­heat­ing.

The build­ing also takes spe­cial care to con­trol day­light glare by lim­it­ing aver­age room depth to 25 me­tres and by keep­ing the ceil­ing rel­a­tively higher at 3.2 me­tres. This has been com­pli­mented by lowen­ergy led task lights at ev­ery work­sta­tion.

En­ergy de­mand has been re­duced to a large ex­tent by re­plac­ing the cen­tral air-con­di­tion­ing (AC) sys­tem with an ex­tremely low-en­ergy hy­brid AC sys­tem. Un­like the cen­tral AC, where cooled air is dis­trib­uted over­head, the hy­brid AC de­liv­ers air through dif­fusers placed on the floor. This en­hances ef­fi­ciency of the sys­tem. It also al­lows par­tial shut­ting down of the AC dur­ing off-peak hours. To fur­ther re­duce the en­ergy con­sump­tion, Agilent uses the AC to cool down wa­ter dur­ing off-peak hours, es­pe­cially dur­ing the night. The chilled wa­ter is then used to run the AC dur­ing peak hours. When com­pared with the con­ven­tional AC sys­tem, these mea­sures have helped the or­gan­i­sa­tion half its en­ergy re­quire­ment for cool­ing.

De­spite us­ing wa­ter-cooled chillers, the build­ing has man­aged to re­duce its wa­ter con­sump­tion by one-fourth by har­vest­ing rain­wa­ter and re­cy­cling wa­ter. It stores rain­wa­ter runoff from its roof in a 5 mil­lion-litre tank. The land­scape has pas­sive drainage wher­ever pos­si­ble, with swales and per­co­la­tions to fa­cil­i­tate rain­wa­ter har­vest­ing. The park­ing area and roads in the cam­pus have been paved with grass to re­duce sur­face runoff and aid in ground­wa­ter recharge. In its three-step wa­ter re­cy­cling sys­tem, mu­nic­i­pal wa­ter is mixed with rain­wa­ter and is used for wash­ing hands. The waste­water is then treated and used for flush­ing, and the treated sewage wa­ter is used in gar­dens.

The cam­pus also has elec­tric sock­ets for charg­ing elec­tric and hy­brid ve­hi­cles.

LO­CA­TION Mane­sar, Haryana COST Not avail­able IN­NO­VA­TION Glaz­ing has been done in a way that it con­trols heat ingress. The build­ing has a hy­brid AC sys­tem that de­liv­ers max­i­mum cool­ing with min­i­mum en­ergy con­sump­tion. To re­duce its wa­ter con­sump­tion, it has a rain­wa­ter har­vest­ing sys­tem and a three-step wa­ter treat­ment and re­cy­cling sys­tem
