What is BIM

• Building Information Modeling (BIM) is a digital representation of physical and functional characteristics of a facility. A BIM is a shared knowledge resource for information about a facility forming a reliable basis for decisions during its life-cycle; defined as existing from earliest conception to demolition.

The US National Building Information Model Standard Project Committee

BIM dimensions - 3D, 4D, 5D, 6D, 7D BIM• Linking extra ‘Dimensions' of data to your information models has the

potential to give you a richer understanding of your construction project - how it will be delivered, what it will cost and how it should be maintained.

6D BIM

The utilization of 6D-BIM can result in more complete and accurate energy estimates earlier in the design process. It also allows for measurement and verification during building occupation, and improved processes for gathering lessons learned in high performance facilities.

What is BEM/EAM

Basically, a Building Energy Model (BEM)/ an Energy Analysis Model (EAM) is an abstraction of a building's overall form and layout into a ‘Computational Network' that can capture all of the key paths and processes of heat transfer throughout the building effectively.

What is BEM/ EAM

BEMs/ EAMs are used in whole building energy simulations, and gbXML is a common format for representing these models.

Why BEM

Having performance-based design rather than analyzingthe design when it’s already done.

Having a better IPD process (A new LEED V4 Credit).

Reduce design costs

Certification Requirements for Green Buildings require a demonstration of improved building performance using a simulation energy model

Autodesk Insight 360

Autodesk Insight 360• Insight 360 is Autodesk’s Solution for building performance analysis, it

was first released in 2015

• It facilitates robust integration with Revit and direct access to guidance and recommendations from trusted simulation engines and industry benchmarks (ASHRAE 90.1, Architecture 2030 Challenge)

Autodesk Insight 360

• Energy Cost Range• identify key energy performance drivers.• measure performance against ASHRAE 90.1 benchmark• making early seamless targeting and feasibility studies

• Quickly Compare Design Scenarios• save and compare your design scenarios to track

performance effects.• Share your insights with project stakeholders and access

all your outcomes anywhere.

Visual Programming and Generative Design for sustainability

Dynamo

• A visual programming tool that aims to be accessible to both non-programmers and programmers alike.

• gives users the ability to visually script, define custom pieces of logic, and script using various textual programming languages.

• Open source graphical programming for design• Could work as a stand-alone application, or Run with Revit (Similar to

Grasshopper and Rhino)

Generative Design

• Generative design is a design exploration process.

• Designers or engineers input design constrains into the generative design software, along with parameters such as performance or spatial requirements, and cost constraints.

• The software explores all the possible permutations of a solution, quickly generating design alternatives.

Evolve

Generative Design

Generative DesignProject Refinery

• is an Autodesk generative design beta project for the architecture, engineering and construction industry.

• gives users the power to quickly explore, evaluate, and optimize their designs.

• lets you create design options, set goals, and optimize for those goals.

Conclusion

• We now have many tools in hand that can reduce the impact buildings have on the environment.

• These tools make sure the right people get the right information at the right time.

• An IPD is now mandatory not a luxury
