Cen­tral to the sys­tem suc­cess is a cus­tom-built glu­lam struc­ture and a ven­ti­la­tion in­no­va­tion by k20 Ar­chi­tec­ture Time­line: 2011-2014

THIS TECH­NO­LOG­I­CALLY ad­vanced, sus­tain­ably-fo­cused new Civic and Ad­min­is­tra­tion Cen­tre is lo­cated in the ru­ral set­ting of Nhill, Vic­to­ria. The build­ing was in­spired by the town’s iden­tity as a hub of wheat pro­duc­tion with steel stor­age si­los and agri­cul­tural sheds dot­ting the land­scape. The precinct re-uses the ex­ist­ing 1960’s build­ing and en­cap­su­lates it within its new con­tem­po­rary built form. The new cen­ter’s form and re­strained ma­te­rial pal­ette of tim­ber, steel and glass gives sub­tle ref­er­ences to the lo­cal agri­cul­tural con­text; util­is­ing the crafts­man­ship of the folded metal in­her­ent in the si­los in the form of lo­cally sourced steel and zinc fin­ishes along the build­ing’s ex­te­rior.

The project is the de­vel­op­ment of Hind­marsh Shire Coun­cil’s new cor­po­rate of­fices and Civic Cen­tre, ac­com­mo­dat­ing 70 staff with ex­pan­sion ca­pa­bil­ity for up to 100. The build­ing pro­vides a level of en­vi­ron­men­tal com­fort and fin­ish which en­ables em­ploy­ees to work in a cli­mate of pro­fes­sion­al­ism more than equal to that found in a cap­i­tal city. Hind­marsh Civic Cen­tre also in­cor­po­rates com­mu­nity-use fa­cil­i­ties, multi-func­tional spa­ces, coun­cil cham­bers, Vic Roads ser­vices and meet­ing and in­ter­view rooms.

ESD Ini­tia­tives- k20 Ar­chi­tec­ture utilised a num­ber of in­no­va­tions to de­liver an out­come that would not only min­imise em­bod­ied en­ergy and en­ergy load­ings within the build­ing, but also re­duce car­bon out­put for the life of the project and pro­vide an en­hanced in­ter­nal en­vi­ron­ment for its in­hab­i­tants. With a 5-hour drive to the near­est cap­i­tal city, the re­mote ru­ral set­ting and harsh cli­matic con­di­tions were in­trin­si­cally linked to the de­sign as well as the de­vel­op­ment of sus­tain­able de­sign in­no­va­tions.

The ex­treme high and low tem­per­a­ture ranges ex­pe­ri­enced in the re­gion re­quires the build­ing’s ther­mal per­for­mance to be at the fore­front of its de­sign.

Cen­tral to the sys­tem suc­cess is a cus­tom-built glu­lam struc­ture and a ven­ti­la­tion in­no­va­tion by k20 Ar­chi­tec­ture that com­bines a tra­di­tional Un­der Floor Air Dis­tri­bu­tion (UFAD) sys­tem with a be­spoke un­der­ground ther­mal cham­ber and earth pipe heat ex­change sys­tem.

The process be­gins out­side where fresh air is drawn into a se­ries of un­der­ground ther­mal PVC pipes. This air then trav­els through the pipes and re­ceives nat­u­ral ther­mal treat­ment, heat­ing or cool­ing the air from the earth be­fore en­ter­ing the build­ing’s UFAD for fur­ther treat­ment. Once the air reaches the UFAD it then trav­els through var­i­ous in­su­lated dis­place­ment plenums and is then dis­trib­uted, at floor level, through oc­cu­pan­tad­justable floor grilles.

The air dis­place­ment sys­tem used for the Hind­marsh Coun­cil’s cor­po­rate of­fices is just one of the many sus­tain­abil­ity mea­sures adopted by k20 Ar­chi­tec­ture us­ing the Green Star rat­ing sys­tem to in­form the de­sign. The build­ing also in­cor­po­rates LED light­ing sys­tems through­out; 72 so­lar pan­els; re­cy­cling of over 80 per cent of the ex­ist­ing build­ing’s ma­te­ri­als; a pri­mary struc­ture of sus­tain­ably sourced lam­i­nated tim­ber beams; zoned me­chan­i­cal sys­tem; pas­sive so­lar de­sign, cross-flow ven­ti­la­tion prin­ci­ples and zoned mo­tion-de­tec­tion light­ing.
