Pun­jab ECBC shall be ap­pli­ca­ble to build­ings with a con­nected load of 100 KW or more; or con­tract de­mand of 120 KVA (kilo volt am­pere) or more; or all build­ings with air­con­di­tioned floor area of 500 sq m (5,000 sq ft) more as this cov­ers most of the big com­mer­cial com­plexes, in­sti­tu­tional build­ings, hous­ing com­plexes in the state. A 3-BHK (bed­room-hall-kitchen) with air­con­di­tion­ers, ap­prox­i­mately con­sumes around 10KW of elec­tric power. So, a group hous­ing so­ci­ety with even 10 apart­ments will have a con­nected load of more than 100KW. Most of such hous­ing com­plexes will be cov­ered by these norms.

The Gov­ern­ment of In­dia en­acted the En­ergy Con­ser­va­tion Act in 2001 to pro­mote en­ergy con­ser­va­tion. It was amended in 2010. BEE was es­tab­lished un­der the Act to de­velop poli­cies to re­duce en­ergy con­sump­tion and co­or­di­nate with stake­hold­ers. “BEE helped de­velop the ECBC. Un­der the Act, states can amend ECBC to suit their con­di­tions. The Pun­jab ECBC is for­mu­lated to meet lo­cal re­quire­ments.

In case of mixed use build­ings, if the con­nected load of the com­mer­cial part qual­i­fies for the ap­pli­ca­bil­ity of this code then the com­mer­cial part of the build­ing also has to com­ply with the code. In case the project is to be built in phases, the Pun­jab ECBC shall be ap­pli­ca­ble to the whole build­ing load in to­tal and not the in­di­vid­ual build­ings de­signed later in phases (as was done ear­lier). Ad­di­tions or al­ter­ations made in ex­ist­ing build­ings and places where air­con­di­tioned floor area ex­ceeds thresh­old area have to be made Pun­jab ECBC-com­pli­ant. All ad­di­tions, to­gether with the ex­ist­ing build­ing have to com­ply with the re­quire­ments of the code.

Al­ready in­stalled space con­di­tion­ing sys­tems (a cen­trally air-con­di­tion­ing sys­tem which al­lows for con­trol­ling of air qual­ity, tem­per­a­ture and hu­mid­ity within a space for hu­man com­fort) do not need to com­ply with PECBC. How­ever, any new equip­ment in­stalled must com­ply with spe­cific re­quire­ment ap­pli­ca­ble to that equip­ment un­der the code.

It will be manda­tory to use equip­ment hav­ing min­i­mum three star rat­ings. Even ceil­ing fans shall com­ply with the pro­vi­sions of the clause. It has also been pro­posed to have au­to­matic shut off (af­ter 10 min­utes) of light­ing fix­tures in com­mer­cial and of­fice build­ings while they are not in use. It also re­stricts the size of win­dows as ex­ces­sive use of glass in this trop­i­cal cli­mate in­creases en­ergy con­sump­tion. Like­wise, there will also be pa­ram­e­ters to in­stall huge sig­nage and ad­ver­tise­ments. It in­cor­po­rates pa­ram­e­ters that can max­imise nat­u­ral light and ven­ti­la­tion.
