PERFORMANCE

Building Performance Analysis is related to LOD (Level of Development), prevents modeled elements from progressing to the next step of LOD in the absence of information. If the answers to discrete questions related to the building behavior have not been found, BIM Performance can be a mechanism for finding answers to these questions and informing the design process.

BIM Performance practices share a feedback loop that at times are not as linear as the steps to developing levels of detail in the BIM model. This may be best explained with the following graphic. :

BIM6 PERFORMANCE-LOD

CONCEPTUAL DESIGN (LOD 100):
•Run conceptual energy analysis using and modifying massing forms and determine the most energy efficient building form.
•Conduct basic shade/shadow analysis of the massing model to determine what areas support daylighting.
•Do solar radiation studies of the mass model to maximize opportunities for solar collection.
•Study how the orientation of the massing model interacts with wind on the site. Orientation of the building can optimized.

DESIGN DEVELOPMENT (LOD 200):
•Run whole building energy analysis of building model, and identify how changes in wall construction can reduce energy demands.
•Complete simulations that determine the general geometry of performative features to determine if project is working as predicted.
•Run interior daylighting analysis of spaces, and confirm proper light levels are being achieved.
•After maximizing the efficiency of the building envelope, run cooling/heating load simulation to size HVAC equipment.
•Perform structural analysis of model so that structural systems can be optimized.

FINAL DESIGN (LOD 300):
•Perform detailed whole building energy analysis of the final design to document expected performance.
•Compare final design against the measurement matrices that were defined in Conceptual Design.
•Perform greenhouse gas emissions analysis to document expected environmental impact.
•Audit final building materials for costs and green qualities (recycled content, close proximity to construction site, low VOCs).

CONSTRUCTION (LOD 400):
•Analyze building quantities to assure that exact material quantities are delivered to the project site.
•Analyze best fabrication methods with digital automation. This step reduces waste material in the production of building assemblies.
•Run construction scheduling simulations that identify how to reduce equipment operations on the project site.

BUILDING OPERATION (LOD 500):
•Perform initial and ongoing commissioning of environmental systems to assure they are working as anticipated.
•Add ongoing utility cost/demand data to energy model, and compare/identify differences between designed and actual performance.
•Administer occupancy survey to verify occupant satisfaction, and make recommendations to facilities management.
