Post-occupancy evaluation or POE is the progression of methodically assessing the performance of buildings after being built and occupied for some time. POE will highlight on the performance of the architectural and engineering systems, the management procedure applied to the design and construction.
With the advancement of time, the concept of Building Information Modeling has changed gradually.
BIM has now changed from a simple planning and design tool to powerful post-occupancy management tool. BIM accumulate the data throughout the construction process and these data can be utilized seamlessly for the maintenance and post-occupancy management of assets (buildings and infrastructure), long after these has been finished.
BIM as a post occupancy management tool gather, store, and share information about successes and failure in processes, products and other building-related areas in order to get better quality and life cycle cost of future buildings. These informations can also be utilized with the planning, programming, and design processes for new facilities to build on successes and get rid of repeating mistakes.
BIM can contain the documentation of owner performance obligations, the design objective and justification, verification and validation of design strategies & decisions to develop actual building performance.
BIM can provide an array of opportunities for project stakeholders that may range from faster communication among team members, the smooth continuation of the project, early detection of errors before happening onto the job site (there zero change orders), precise construction cost estimation and less waste with a mechanical process. Even with the time required by a steeper learning curve, the building was completed ahead of schedule.
BIM contains accurate geometry and information to aid in scheduling, cost comparisons, fabrication, construction, and facility operation.
Construction sectors can experience a low-carbon future with BIM as the tool comes up with greater productivity, risk management, improved margins and sustainability.
After completion of the project many organizations like hospitals and universities, apply sensors and examines overlaid on 3D graphics to analyze the efficiency of the finished structure and its interior spaces. Besides, BIM can also be applied to inventory space use by some facility management departments.
BIM provides an uninterrupted procedure of consistently appraising the execution and/or potency of one or more aspects of buildings like accessibility, aesthetics, cost-effectiveness, functionality, productivity, safety and security, sustainability, environmental design evaluations, environmental audits, building-in-use assessments, building evaluation, facility assessment, and building performance evaluations.
By applying BIM the owner can better realize the effect of early design delivery decisions on long-run efficiency and effectiveness of buildings as well as building delivery processes and decisions on customer response both in the beginning and over the life cycle of the building.
BIM contains specified information set known as COBie1 which delivers uniform and structured asset information helpful to the owner-operator for post occupancy decision-making.
BIM can also be implemented for enhancing Globalization of the construction supply chain and more homogenization and greater consistency of basic construction-client information demands. This information is now progressively driven by national regulation on energy performance and carbon' accounting.
