1 The overall aim of this study was to provide a detailed post occupancy evaluation of a small scale healthcare environment which can in turn inform the future design of similar typologies within the NHS and other healthcare agencies.
2 The study had four key objectives:
1. Tocarryoutanin-depthqualitativereviewofusersresponsetotheDundeeMaggieCentre
2. Tocarryoutatechnicalreviewofthebuilding’sphysicalperformance
3. Toevaluatethedesignandconstructionprocess
4. Todevelopacross-evaluativemethodologyforwideruseinsmallscalehealthcarebuildingsinordertoimprovethebriefingprocess
3 The study specifically aimed to establish:
a) theeffectivenessofthedesignconceptintermsoftheoriginalbriefandcaremodel
b) theoverallusersatisfactionwiththebuilding
c) theextenttowhichpeopleperceivethebuildingascontributingtotheirsenseofcomfort,wellbeingandhealth,andthepossiblemechanismsforthis

Visitors tended to chat in the bright kitchen; the common room was used for group activities

Lack of storage space and cramped office space may hinder effective working
People come to the Dundee Maggie’s Centre mainly by car, leading to parking problems

H The building process
1 AnArchitectrepresentativewasinterviewedseparatelyusingquestionswhichrelatedspecificallytotheconstructionofthebuilding,maintenance,managementandenergyefficiencyinaseparateTechnicalInterviewGuide(AppendixI).Theresultsoftheinterviewwereanalysedinrelationtoacarefulexaminationoftheworkingdrawings,specificationsandheatingbillsforthebuildingtoprovideanoverallappraisalofsustainability.A“walkthrough”withtheClientRepresentativewasusedtofurtherclarifyidentifiedissues.Thebenefitofhindsightwasusedtoestablishwhat,ifany,additionalchangesmightbemadetothefuturebriefing,design,specificationandconstructionofsmall-scalehealthcarebuildingssuchasMaggieCentres.
Construction process

Management
9 Accordingtothelocalarchitect,theperformanceofthebuildinghadgenerallyfulfilledthebriefrequirementsapartfromtheofficearea,wheretheergonomicswerenotthoughttobeoperable.TheofficedidnotcomplywiththeDisabilityDiscriminationAct,becauseitwasnotpossibleforawheelchairusertoworkintheoffice.Itwouldbepossible,however,forawheelchairusertobeaccommodatedelsewhere,giventheflexibilityofthebuilding.

11Generally,althoughthebuildingwasfelttoworkwellandhadacompletelackofinstitutionalfeeling,thelocalarchitectsuggestedthatthebriefwasnotcomprehensiveenough.Neverthelessthedesignwasratedbyhimas“prettyclosetoexcellent”.
12The“walkthrough”revealedthatsightlinesfromthePCinformationstationandthekitchenareastotheentrancedoorwereblockedtoadegree,leadingtostaffhavingtopositionthemselvescarefullyatalltimestoensurethattheycouldhear/seevisitorsarriving.Thiswas,however,viewedpositivelyasitensuredthatstaffremainedattentivetoallpartsofthebuilding.
Energy efficiency
13Theprimarymeansofheatingthebuildingwasbyunderfloorheatingusingadomestic30kWcombinationgasboilerforthegroundfloorwetsystemandelectricityfortheupperfloorunderfloorheating.A6.6kWwoodstove-effectgasfireprovidedadditionalheatingtotheupperlevelareaabovethelibrary.Thewetsystemwasdesignedtoberunataconstanttemperaturesettingofaround18˚Cwithlocalisedheatingelementsinthekitchenareaandlargegrouproomtotopthisupasrequired.Theunderfloorheatingwassplituptoeightdifferentzonesrelatingtodifferentpartsofthebuilding,eachwithaseparatethermostat.Thesecouldonlybeadjustedbyoneortwodegrees,however,fromthemainprogrammesetting.Thelocalarchitectwasnotconvincedbythecontrolmechanismforthelocalisedheatingelementandatthetimeofthisstudytheheatingcoilitselfappearedtobemalfunctioning.

14Serviceengineer’sreportsnotedseveraltimesthattheheatingprogrammerwasonthewrongsettingsandhadtobereset.Therehadalsobeensomepastproblemswiththeheaterunderthebenchunitinthekitchenandintheofficearea.Itisquiteclearfromtheengineer’sreportsthatstaffregularlyreportedproblemswiththeheatingwhichwerelargelyrelatedtothecomplexityoftheprogrammer.Theauthoralsoobservedthecomplexityofusingtheprogrammerduringthe“walkthrough”.

Overall sustainability
