The Revit Conceptual Energy Analysis software native to Revit 2012 offers the ability to perform energy analysis from very early stages within the design process. These are fairly intuitive tools if you are familiar with the massing tool itself. These are not by far the most comprehensive tools used today and it is often stated that energy analysis should be left to the professionals. I agree that highly detailed simulation should probably be left to the experts at present but having these Conceptual Energy Analysis tools native to BIM software offers better design intent from the outset.
Energy Analysis Tools native to Revit may also help the modeller to build the model in a way that is compatible with other more detailed building physics software. It is so often the case that Revit models are built without energy solutions or simulation in mind, therefore errors or clashes occur once handed over to the experts. Either this or they are handed over too late in the design process in-turn causing delays. Conceptual Energy Analysis offers environmental solutions from the word go.
The Conceptual Energy Analysis in Revit consist of 3 easy to use tools:
In reality the more information contained within the BIM model the more successful the project should be saving time and money.
With the use of an internet mapping system it is easy to locate the project to the exact site and locate the closest weather stations. This is a great tool to get accurate local climate conditions whilst giving you other useful regional information including Latitude and Longitude.
It may also be worth noting what the Sliver Space Option is (Often referred to as Silver Space). Sliver Space is used within the analytical model rather than the physical model where there is a small gap or area where a room would not be placed. These areas can typically include areas between old and new structures that have been boxed out or simply between two walls.
Areas to large to be classed as Sliver Spaces may need rooms adding, try to avoid leaving areas of voids throughout the model as this will impact on the accuracy of the energy results. Accuracy is all important when creating models for energy analysis and the more work / effort you put in from the outset the better the results when you come to run the energy analysis. It’s all about preparing the model correctly, taking your time and not rushing into these things.
The Energy Settings dialogue box below is where most of the work is done to build up the information within the massing model for your design. The parameters within the dialogue energy settings offer control over the following:
Anytime throughout the stages of the design you can go back and revise the design to however you wish. The option is also there to do multiple layouts of the same project and compare all the layouts against one another once you run the Analyze Mass Model.
Once you are happy with your model and the parameters you need to run it through the Analyse Mass Model tab.
Example Massing Model 30% glazing and 1% roof light
The results only take a few minutes to process and are presented in an easy to understand graphical manor. This is particularly useful for clients to understand and evaluate the information presented.
