3. Introduction Sustainability has become a mandatory requirement in many building codes In Qatar GSAS Certification is a part of section 7 QCS 2014GSAS Certification On the other hand in recent days BIM is playing a key role in design, construction and operation of buildings This presentation discusses how BIM can effectively used deliver sustainability in projects.

4. What is BIM? BIM is an abbreviation of Building Information Model.Building Information Model A BIM Model of a building is an intelligent Computer Model to create, modify, collaborate and coordinate information throughout the lifecycle of the building ie Design, Construction and Operations Phase. The information stored in the BIM Model plays a key role and makes it special compared to conventional 2D or 3D © 2017 Conserve Solutions. All rights reserved 4

5. BIM Vs Conventional Model A wall in a conventional model is a box with the given dimensions Non Parametric It replicates the physical wall and reflects its properties such as materials, finishing, thermal properties, structural properties etc Parametric: When modifications are made in wall, the change is reflected in all associated elements. Example when the height of wall is reduced, the roof attached to wall automatically comes down © 2017 Conserve Solutions. All rights reserved 5

6. What is Building Performance Analysis? Building Performance Analysis is done to evaluate the following during the design stage – Orientation of the building – Thermal Performance of the building envelope – Cooling Load and Heating Load of the building – Lighting and Daylight – Impact of shading of adjacent structures – HVAC system Performance HVAC system Performance © 2017 Conserve Solutions.

7. How BIM makes BPA easier Traditionally each element in BPA is done using different tools but with BIM Model complete Performance Analysis can be done with a single tool like REVIT © 2017 Conserve Solutions. All rights reserved 7

8. Orientation Analysis  Orientation of the building is evaluated with sun path diagram which in turn depends of the location of the building.  BIM will the precise coordinates of the building which makes it easier to perform sun path analysis and hence evaluate various orientations and architectural features such as shading devices of the building © 2017 Conserve Solutions.

9. Thermal Performance of Building Envelope BIM Model will have the thermal properties such as – Thermal Conductivity – U Value for glazing/Curtain wall – Shading coffined – Reflectance – Absorbvity of the building envelope elements such as external wall, roof, windows, curtain walls etc. The thermal properties along with orientation will be used to evaluate Thermal performance of the building © 2017 Conserve Solutions.

10. Cooling Load and Heating Load Calculation All information required to calculate the cooling load or heating load is part of the BIM model. This includes – Orientation of the building – Building envelope properties – Occupancy details Hence BIM tools like REVIT can be used instead is using separate tools like HAP, Trace etc © 2017 Conserve Solutions.

11. Lighting & Daylight Simulation Traditionally Daylight simulation is done through Autodesk software ecotect and lighting simulation is done by Dialux or equivalent software. With BIM since the glazing properties and luminaire data is a part of the BIM Model, it can be done using BIM Software such as REVITBIM Model © 2017 Conserve Solutions. All rights reserved 11

12. Shading Analysis  Shading analysis requires the location of the building and adjacent structures. Given this information to the model.  BIM Model can be done to perform shading analysis © 2017 Conserve Solutions. All rights reserved 12

13. HVAC System Performance  Generally Energy modeling and simulation software such as eQuest is used to evaluate various HVAC system types.  Given the HVAC performance details as BIM Model input in addition all the inputs discussed before.HVAC performance  The model can be used to evaluate HVAC system performance © 2017 Conserve Solutions.
