 Analysis	  Fall	  2014	  	  Project:	  St.	  John’s	  College	  Residence	  building	  2010-­‐2014	  	  	  By:	  Priyanka	  Chakrabarti	  Master	  of	  Science	  in	  Planning-­‐2016	  SCARP,	  UBC	  	  	  *Although	  the	  charges	  are	  applied	  in	  Cubic	  Ft.	  all	  the	  charts	  are	  created	  using	  the	  values	  in	  Cubic	  meters.	  	  Introduction	  	  The	  data	   provided	   in	   this	   paper	   represents	   the	  water	   consumption	   as	  per	  the	  meter	  readings	   from	  St.	   John’s	  College	  residence	  at	  UBC.	   It	   is	  a	  graduate	   residential	   college	   with	   a	   kitchen	   (data	   not	   included	   here),	  common	   spaces,	   several	   studio	   and	   single	   bedrooms	   as	   well	   as	   guest	  rooms.	  	  St.	  John’s	  College	  accepts	  graduate	  students	  year	  round	  and	  also	  hosts	  visiting	  professors	  from	  all	  over	  the	  world.	  	  	  Data	  Collection	  and	  analysis	  	  The	  data	  in	  this	  paper	  was	  obtained	  from	  the	  power	  house	  at	  UBC	  (STC	  is	  customer	  #329)	  and	  includes	  57	  data	  points	  for	  the	  years	  2010-­‐2014.	  	  The	   graphs	   have	   been	   done	   using	   the	   consumption	   readings	   in	   cubic	  meter.	  No	  renovations	  have	  been	  done	  in	  this	  building.	  	  	  Calculations	   for	  measuring	   the	  consumption	  have	  been	  done	  using	   the	  following	  formula:	  	  [(Current	  High	  Flow	  meter	  reading-­‐	  Previous	  high	  Flow	  meter	  reading)	  +	  (Current	  low	  flow	  meter	  reading-­‐	  Previous	  low	  flow	  meter	  reading)]	  x	  	  35.314475	  (conversion	  rate	  to	  cubic	  feet)	  *Although	  the	  charges	  are	  applied	  in	  Cubic	  Ft.	  all	  the	  charts	  are	  created	  using	  the	  values	  in	  Cubic	  meters.	  	  There	   were	   several	   inaccuracies	   in	   the	   data	   provided	   for	   the	  consumption,	   hence	   all	   the	   consumption	  values	  were	   recalculated	   and	  then	  used	  for	  preparing	  the	  charts.	  From	   the	   chart	   below,	   there	   seems	   to	   be	   a	   sudden	   dip	   in	   the	  consumption	  in	  June	  and	  then	  a	  sudden	  increase	  in	  values	  in	  July,	  which	  is	  quite	  odd	  and	  probably	  indicate	  something	  missing	  from	  the	  readings.	  The	   highest	   recorded	   value	   for	   water	   consumption	   was	   in	   November	  2012.	  The	  inconsistencies	  and	  sudden	  dips	  and	  rise	  in	  values	  disappear	  after	  April	  2013	  as	  the	  readings	  see	  to	  show	  a	  gradual	  rise	  or	  fall	  of	  the	  numbers	  without	  any	  drastic	  change.	  	  	  fig	  1.1	  0	  500	  1000	  1500
