En­ergy ef­fi­cient Bay­side Mall lauded by city

Mall wins award to lead green ethos

Weekend Argus (Saturday Edition) - - PROPERTY -

GROWTH­POINT Prop­er­ties’ Bay­side Mall has been named a win­ner at the 2015 En­ergy Ef­fi­ciency Fo­rum Awards.

The City of Cape Town, in part­ner­ship with Eskom and the South African Property Own­ers As­so­ci­a­tion (SAPOA), launched Cape Town’s En­ergy Ef­fi­ciency Fo­rum (EEF) in 2009 to as­sist com­mer­cial build­ings and oper­a­tions im­prove their en­ergy ef­fi­ciency.

Bay­side Mall in Ta­ble View scooped the award for the large build­ing retro­fit cat­e­gory, rais­ing the bar for en­ergy ef­fi­ciency at shop­ping cen­tres in Cape Town and across the coun­try.

The mall’s en­ergy ef­fi­ciency in­ter­ven­tions in­clude up­grades to LED light­ing and im­prove­ments in the heat­ing, ven­ti­la­tion and air-con­di­tion­ing sys­tem.

The projects have yielded con­sis­tent monthly en­ergy sav­ings av­er­ag­ing at 11 per­cent so far, with the hot sum­mer months ex­pected to bump sav­ings up to 17 per­cent.

Growth­point chief ex­ec­u­tive, Nor­bert Sasse, says: “Win­ning this award shows we are on the right track to achiev­ing our own green goals, and we hope it also in­spires oth­ers to do the same, go­ing be­yond what’s re­quired to en­sure we are re­source-ef­fi­cient and pre­serve our en­vi­ron­ment as best we can.”

Growth­point is South Africa’s largest REIT and a JSE ALSI Top 40 In­dex com­pany. It is a Plat­inum Found­ing Mem­ber of the Green Build­ing Coun­cil South Africa (GBCSA), a JSE So­cially Re­spon­si­ble In­vest­ment (SRI) In­dex com­pany and a Dow Jones Sus­tain­abil­ity In­dex com­pany.

It owns and man­ages a di­ver­si­fied port­fo­lio of 471 prop­er­ties in South Africa, 53 prop­er­ties in Aus­tralia through its in­vest­ment in GOZ and a 50 per­cent in­ter­est in the prop­er­ties at V& A Wa­ter­front. Growth­point’s con­sol­i­dated property as­sets are val­ued at over R100 bil­lion.

Stephan le Roux, Growth­point’s divi­sional di­rec­tor for re­tail, says: “Our sus­tain­abil­ity projects that pro­duce so­lar en­ergy, har­vest rain­wa­ter, and con­vert waste into en­ergy all make Bay­side Mall more self­suf­fi­cient by gen­er­at­ing its own en­ergy and re­duc­ing its waste to land­fill.”

Bay­side Mall’s flag­ship project was a 500kWp pi­lot rooftop so­lar pho­to­voltaic (PV) plant, with 2 108 pan­els cov­er­ing 3 300m². It sup­plies 5 per­cent of the elec­tric­ity needs in this shop­ping cen­tre, which spans over 45 000m² of re­tail space and wel­comes in ex­cess of 7.5 mil­lion shop­pers each year.

“The an­nual av­er­age daily en­ergy pro­duc­tion of th­ese pan­els is 2 100 kWh, which equates to the av­er­age daily use of 150 house­holds in Cape Town. The in­stal­la­tion of the PV pan­els has also re­sulted in car­bon emis­sion re­duc­tions equiv­a­lent to 767 tons of CO2,” says Le Roux.

The mall has also in­vested in a rain­wa­ter har­vest­ing and re­use in­ter­ven­tion. This in­volves the ex­trac­tion, de­tain­ing, stor­age and util­i­sa­tion of stormwa­ter run-off from the shop­ping cen­tre’s hard sur­faces and rooftop.

This re­sults in a 93 per­cent wa­ter saving in land­scap­ing and pub­lic toi­let us­age.

The mall’s waste-to-en­ergy in­ter­ven­tion in­volves the anaer­o­bic di­ges­tion of or­ganic waste that is gen­er­ated in the shop­ping mall each day. A waste-to-en­ergy elec­tric­ity gen­er­a­tion plant has been con­structed and will in­tro­duce a fur­ther 250 to 330kWh a day in the near fu­ture.

This will be fed back into the mall for use in pow­er­ing in its com­mon ar­eas.

SAV­INGS: The 2 108 so­lar pan­els on the roof of Bay­side Mall in Ta­ble View gen­er­ate 500kWp.
