<strong>ACTA</strong> <strong>TECHNICA</strong> <strong>CORVINIENSIS</strong> – BULLETIN <strong>of</strong> ENGINEERINGchange. The government attentively focused onformer open space available in the city like TKB,Sparta Tikala and seaside area. Meanwhile greeninfrastructure at the housing areas has just beenthe complementary objects, either in planningand provision or in management. Objective <strong>of</strong>the study is to conduct a design review <strong>of</strong> somepublic open space available as a framework inwhich to evaluate the accessibility and usability<strong>of</strong> each space for the public, in order to promoteenvironmental quality. Preiser (1988) stated thatspace performance could be identified by 3elements; they are technical, function andbehavior aspects. Research tried to evaluatespace performance <strong>of</strong> public open space inManado, which emphasized on those 3 aspects.Technically, spatial design review focused ondimension <strong>of</strong> space in order to know adequacyratio <strong>of</strong> space, sanitation and fixtures throughenvironmental perception <strong>of</strong> the visitors.Functionally, evaluation was conducted byexamine spatial usability and accessibility, andkinds <strong>of</strong> activities expected from usersperspective. Behavioral aspects concern aboutobservation <strong>of</strong> behavior setting occurs in sites,orientation ability, users’ interaction with thewhole elements available in place, and user’ssatisfactory in using the place.METHODSSpace performance in architecture, indoor oroutdoor, determined by several things. In case<strong>of</strong> outdoors, it could be designed by provisionsupporting elements like trees, sculpture, pond,or benches. All these elements should be wellinterpreted by individual senses. Explorationabout human perception against spaceperformance examines how far the combinationelements enable to stimulate the positivefeelings <strong>of</strong> human being. Method used in thisresearch is development <strong>of</strong> Post OccupancyEvaluation (POE) whereas the application <strong>of</strong>POE is frequently used for evaluation theeffectiveness <strong>of</strong> design interior in singlebuildings (Zimring C M, and Reizenstein J E,1980). POE for outdoor facilities and other builtenvironments could be ensured to promotephysical environment more human and couldimprove urban environment quality <strong>of</strong> life in thefuture. POE is defined as a systematic processfor evaluation <strong>of</strong> built environments from user’sperspectives. It is used to identify ways toimprove quality <strong>of</strong> environment, to raisecomfort and productivity <strong>of</strong> users, and to reducedesign and maintenance cost. In this study, POEwas conducted in 3 aspects <strong>of</strong> spatialperformances: physics, functions and behaviorto explore user-centered design guidelines forsuccessful design <strong>of</strong> similar objects. Phases <strong>of</strong>POE to evaluate spatial performance are:1. Observations <strong>of</strong> the place to identify who,where, when and, possibly, how users spendtheir time;2. Survey determination and administration tousers <strong>of</strong> the place for quantitative (statistical)measurement <strong>of</strong> the environment;(questionnaires)3. Interviews <strong>of</strong> users regarding theirexperiences with the place; this helps toqualify where and how people spend theirtime in certain places or corners and notothers;4. Behavioral and Preference Mapping <strong>of</strong> theplace, possibly at different scales, todelineate those areas that receive the mostand least amount <strong>of</strong> use, as well as toquantify and qualify the reasons for the use;5. Photographic analysis <strong>of</strong> how people use thespace, as well as key measurements thatdemonstrate how people are either engagedor not connected to the environment.Baker (1968) defined the basic unit for behaviormappings are behavior setting which arecomprised <strong>of</strong> suitable combination betweenactions and its place/milieu. Meanwhile Ittelsonmarked, in general, behavior mappings follows 5steps <strong>of</strong> procedures:1. Basic sketch <strong>of</strong> setting area2. Description and diagrams <strong>of</strong> behavior setting3. Duration <strong>of</strong> observation.4. Systematic procedures5. Notation / coding300 respondents from different age groups wereparticipated in the research for answering thequestionnaires, followed by interviews andobserved behavior setting to explore the properneed <strong>of</strong> open space users. Three types <strong>of</strong> urbanoutdoor spaces in Manado were observed. Firsttype is Urban Plaza in city central TamanKesatuan Bangsa (TKB) and Sparta Tikala,Secondly is waterfront areas (Bahu Mall andMegamall seaside area, and Neighborhood openspace in Ketang Baru and Bantik.1202010/Fascicule 2/AprilJune /Tome III

Map <strong>of</strong> Manado CityRESULTS AND DISCUSSIONSUMMARY DESCRIPTIONURBAN PLAZA / CENTRAL SQUARE (TKB ANDSPARTA TIKALA)TKB is an old square plaza on the CentralBusiness District area in Manado. Surrounded bycommercial building, this square has historicalbackground and become an important placebecause it has been designed since early period<strong>of</strong> urban growth. It has been removed (renewed)from times to times according to urbanredevelopment process. During <strong>of</strong>fice hours, thissquare is intensively occupied by users forpassing through from one side to another. Most<strong>of</strong> the visitors use the square as a pedestrian wayto reach the local transportation. Some othersused as a resting area to take a break after doingtheir shopping around the site. For the last fewyears, local authority has built an open theatrein the square for making this square moreattractive. On the evening hours, the placebecome so quiet because all the stores adjacentwere closed, and no activities surround. In 2007Sparta Tikala is a formal open space, a civicspace with lawn court and trees, created in front<strong>of</strong> local government <strong>of</strong>ficial buildings. It hasjogging track and benches insides. There arevarious decorative elements and functions onthe site. People use the park for playing or doingsome exercises, social gathering, ceremony, orother special events. Sometimes they use forexhibition and promotion affairs. During the day,this place is relatively quiet. On the north andsouth sides, outside the park, there arepedestrian ways with seats under big trees thatformed comfortable space for shading. Althoughthe park has lower density <strong>of</strong> usage, theexistence <strong>of</strong> place gives particular impression forinhabitants.Waterfront AreasAnother kind <strong>of</strong> open space in the city is coastalzones that exist along 20 km <strong>of</strong> Manado coastallines. One <strong>of</strong> the most successful design forpublic open space is Bahu Mall recreationcenter. People <strong>of</strong> Manado enjoy much havingmeals in many occasions, particularly duringrecreation time. This social phenomenon leadsthe authority to provide many cafeterias in therecreation center like Bahu Mall and Mega Masseaside area.
