CONSTRUCCIÓN SUSTENTABLEple or teams and are becoming more expensive.This is why the information derived from theanalysis and study is critical in the early designstages, where the curve of the skill is in thehighest point and the curve of cost at the lowestpossible; this is achieved, in large as withtechnological tools, experience and knowledgeof the integrated team.The design that involves sustainability andcurrent requirements, is greatly benefited bythis process of documentation and the focus ofthe effort curve, from the perspective of life cycleassessment of a project using BIM (BuidingInformation Modeling) technology as a tool, itis certainly not the only way, but research conductedby McGraw Gil, show that an integratedprocess can reduce by up to 57% of conflictsarising from a documentation process, withouta methodology and the appropriate tools. Additionally,there are savings of up to 11% fromerrors in the documentation process of project,savings in change orders, field corrections andendless problems the construction is plagued,and all translate into money loss due to badpractices. Considering that the volume of constructionindustry in our country is around 7.8%of GDP according to the 2011 CNIC, report,then the losses can be very significant.BIM, understood as a set of computer programs.Can be seen simplistically as a modelingsystem, in fact, is a correlated database, whichpresents information in graphic or written,understandable to all members of the designteam. In the early stages of the project is atool for mass analysis of the layout, and returnsvaluable information on the expected efficiencyof buildings through programs for analysis ofenergy models, we can determine the best orientationfor a building or a set of them, you cananalyze the heat gain and define the most appropriatefaçade system. Through graphic illustrationsof the prevailing winds, temperaturesand insolation, you can define the best positionof trees in a campus and alleviate temperaturein hot sites or allow heat gain in cold areas.This tool helps us to study the conditionsfor interior lighting and design more efficientand responsive systems of artificial light. Wecan also study the acoustics of a space and selectthe most appropriate materials for interiorcomfort. It also allows us to know the quantitiesof recycled material, its source and find outwho is the manufacturer, we can feed the databasewith accurate cost information, guarantees,maintenance and operation requirements,demands and production of any material that iswithin our model.SUSTAINABLE DESIGNPROCESSGood buildings do not just happen. These areplanned to look good and perform well, and comeout when good architects and, above all, goodcustomers meet in reasonable and cooperativeeffort. To program the requirements for a proposedbuilding is the first task of the architect,often the most important and least understood.There are some underlying principles thatapply to the program-for either more complexhospital or a small home. Entire books havebeen written that speak of this systematic processand for now, what it is to note is the greatimportance of a clear and early definition of theobjectives of the architectural project, from theeconomic, functional, aesthetic, time and sustainabilityaspects.It is essential to bring together all participantsin the design process as soon as possibleand make clear the objectives set by the program,so that each gets the more and clear informationabout the project. In parallel, a workingmeeting takes place in which is the objectivesare analyzed from the perspective of eachof these participants, and the impact these objectivescan have on a sustainable certificationprocess, this is known as “Sustainable DesignWorkshop” or “Sustainable Design Charrette”.If there is a certification system to follow,then a card of sustainability targets or “ScoreCard” is made to follow, it is discussed in asmuch detail as each of the items and together itis decide what are the best strategies to follow,establishing roles and responsibilities to eachof the participants.One of these participants is the “owner”or customer, represented by a person requiredto provide as much information as possible, receivethe analysis of each item and make decisionsthat shape and the direction to projecttoward the goal. In some cases, this person willwrite papers describing in technical detail theexpected performance of the project in each oftheir systems, which should be rules to followand applicable standards in each discipline.During the design process, the design teammust submit documentation necessary to describeclearly how they are to meet the requirementsestablished by the owner. There must bea person or group to objectively analyze technicalinformation and opinion as to whether itmeets these requirements, preferably someoneoutside the design process who can go directlyto the owner. These procedures are cyclical andcontinuous during the life of the project in orderto make corrections during development.Once the time to initiate the works arrives,the design process has to be closed and, confirmingthat everything that was set in the “DesignCharrette” has been completed and documented,what has not been possible to achieve,must also be documented and explained forfuture reference.The contract or contracts for work, mustestablish that there is a sustainable strategyand that the contractor must abide by it anddocument everything that has been establishedsince the beginning, hence the importance ofintegrated process where the contractor is withthe project team from early in the process, thisis an issue that can lead to discussions and explanationspaths in future collaborations.During the work, must ensure that the executionis carried out under established guidelinesand the documentation process is carriedout to be evidence to the owner and the authoritywho requires it (if you have chosen someform of certification) that the work has beenperformed according to the plans.Once the work has substantially completed,the kick-off procedures take place for startingand operating under the standardized protocolsof systems that require it. It is verified that theoperation of the building was initiated accordingto the conditions established by the rulesfollowed during the design, these may includefilter changes, flush-out procedures and someother individuals depending on the chosen certificationsystem.After the occupation of the building, theycan conduct surveys of comfort, training, operationand monitoring systems, this stage canlast several months.Finally, it is necessary to develop a casestudy document, which synthetically describesthe most relevant strategies and features of theproject. This is done in order to set a precedentand make available other information that maybe useful for similar projects. •88www.inmobiliare.com
