Designed  by  NORR  Ltd.  /  MTBA  Architects  &  Associates   CERTIFIED  APRIL  2016

The  Bank  of  Montreal  Renova2on  is  a  3-­‐storey,  4,867m2  office  and  conference  building  located  at   144   Wellington   St.   in   OYawa,   ON.     The  renova2on   is   an   addi2on   connected   to   the  original  Bank  of  Montreal  heritage  building  and  is   now   home   to   large   parliamentary  mee2ngs  and   func2ons.  By  earning   the  highest  possible  ra2ng  (5  Globes),  this  project  surely  serves  as  a  na2onal   or   world   leader   in   energy   and  environmental  performance.        A  sustainable  contribu2on    to  the  community   The  Bank  of  Montreal  Renova2on  building  was  able   to   incorporate  many  energy-­‐efficient   and  environment-­‐friendly   features   including   a  green  roof,  energy-­‐efficient   lights  and  sensors,  low-­‐flow   faucets   and   toilets,   HVAC   energy  management,   and  more.     The   team  was   also  able  to  reduce  the  overall  embodied  energy  of  the   project   through   efficient   transporta2on  and   by   taking   advantage   of   the   exis2ng  materials   from   the   original   Sir   John   A.  Macdonald   building.     Reuse   of   limestone   and  other   materials   were   used   to   repair   the  masonry   and   refurbish   the   interior,   as  well   as  re-­‐appropria2on   ini2a2ves   of   former   marble  tellers’   counters   and   benches.     Through   an  Integrated  Design  Process  (IDP),  Environmental  Purchasing   strategy,   and   Commissioning   Plan-­‐Documenta2on   process,   the   project   was   able  to   bring   together   various   stakeholders   and  prepare   strategies   that   successfully   reduce  waste,   conserve   energy,   and   minimize   the  environmental   impacts   of   the   Bank   of  Montreal  Renova2on.    

Mee2ng  future  needs    Knowledge   of   the   microclimate   of   a   site   can  influence  decisions  regarding  building  placement  and   orienta2on,   building   design,   and   landscape  features.     This   can   include   measures   such   as  those   to   reduce   the   urban   heat   island   effect   or  “light  pollu2on”  of  the  night  sky.    This  project  has  taken   ini2a2ve   to   address   many   of   these  contemporary   issues.   The   green   roof   is  accompanied  with  high  albedo  materials  to  help  reduce   unnecessary   excess   ambient   heat   in   the  city  while  offering  a  natural  habitat  for  birds  and  other  small  animals.  The  green  roof  will  also  help  with  rainwater  management  by  absorbing  water  and  reduce  runoff.  In  addi2on,  obtrusive  aspects  of  exterior  ligh2ng  such  as  light  trespass  and  sky  glow  were  me2culously  avoided  to  preserve  the  nocturnal  sky.      Overall   energy   consump2on   is   an   important  ini2a2ve   and   is   in   line   with   Canada’s   na2onal  energy   targets   for   coming   years.     The   Bank   of  Montreal   Renova2on   has   been   designed   to  perform   21%   beYer   than   the   Model   Na2onal  Energy  Code  for  Buildings  reference,  and  has  an  es2mated  energy  use  of  9,176  GJ/yr.
