For a couple years now many IES has placed much of there development efforts towards compliance with the Performance Rating Method of ASHRAE 90.1 (LEED Energy Modeling). What we saw during this time, however, was mostly a new look and more of those buttons. The most frustrating part was that IES had LEED written all over their product, being able to demonstrate compliance on a large number of

With the growing emphasis on energy efficiency and Integrated Design, we are seeing more and more tools emerging to aid in energy efficient design analysis. Design Builder isn't entirely new, but after last year's added gbxml functionality, Design Builder has become a very capable addition to the Integrated Design toolbox.Much like IES and eQuest, Design builder is a heavy-duty energy modeler

In my previous post I mentioned interoperability issues the gbxml import to Bentley Hevacomp. In this post I plan to show examples, specifically of taking a model from Revit into Hevacomp.The example shown below comes from a university studio project where students had to take existing buildings and re-design them to perform better. Students working with non-residential buildings had to evaluate

Bentley Hevacomp deserves a lot of credit for becoming the first program to hit the big 3: importing XML format, visualizing the model, and being able easily run an ASHRAE 90.1 energy simulation.What exactly do each of these mean?Import XML: Buildings created by architects can quickly be imported into energy modeling programs.

An early release of the Solar Radiation Technology plug-in for Revit will allow users to give feedback during the development of this feature.

With the April launch of LEED v 3.0 the US Green Building Council has made a huge shift in their priorities concerning energy consumption. EA Credit 1, Optimized Energy Performance has always been the biggest potential point getter with 10 available, yet it is often underutilized.Recognizing the neglect of energy credits for other low-hanging-fruit, the USGBC has raised the stakes in version 3.0

To save time and energy I'm attaching a link to the Bimology post on the same topic. Without re-hashing any details I plan to dwell on only a couple of things: shading devices and curtain walls.When exporting to gbxml you now have 5 settings for how Revit will translate the model. You can either export as "simple" or "complex" which determines whether or not glazing will be broken up by mullions.

The 2010 release of Revit Architecture has made a huge improvements in form generation, gbxml exporting, and what makes me most happy, new tools for surface subdivision.First let me apologize that these buildings are less than spectacular, I had to rush to get this post out before my nemesis, Tzigo (who's actually a really nice guy, to his disadvantage), could do it and take credit.

Warning!!I first reviewed Ecotect Analysis 2010 before I had begun using Revit Architecture 2010. My updated post on gbxml 2010 goes into much more detail about the translation of Revit shading devices. Be sure to read both posts. The development of BIM energy modeling has often been plagued with shading device difficulties, but the tools are getting better all of the time.When you export to

The most appropriate workflow for early analysis is to began designing within the BIM application. At this stage you can utilize the geometry for massing and orientation analysis, while also setting up thermal zones to began the process of energy modeling. But perhaps most crucial to this process is the guarantee that your model always contains the latest information, so that any change to the

IES Virtual Environment is a comprehensive energy modeling and environmental analysis tool which can simulate just about everything happening to your building. Past use of Virtual Environment existed mostly outside of the architects' realm, however IES has done much recently to integrate their tools into the architectural process with push-button toolkits.The strength of the toolkit is that it

Part 2 is the response to the LEED CIR posted in Part 1First let me explain the title. The words "Beyond LEED" are not meant to criticize the LEED rating system but only to critically evaluate the LEED analysis requirements against more advanced analysis capabilities available.

If you say that you are using BIM because you care about sustainability, you could end up misleading people, including yourself. If you say that you are using BIM so you can conduct Building Performance Analysis, this could be an accurate statement but only if you know exactly where you are going with it.Do you know exactly where you are going with it?

In this follow up to the "Chicken or Egg" blog I'm attempting to clarify the process, still misunderstood by many.First it needs to be recognized when designing high performance buildings that we are too limited if we rely on a single energy model which simply calculates overall loads. The concept of multiple models appears inefficient and a departure from what we want out of BIM, but is a

It is well known in the industry that energy analysis used to improve design has the greatest impact at the very earliest stages of a project.One must add to this that the costs associated with making changes is least also at the earliest stages of the project. *But the effort to push energy analysis to the front of the project has run into a couple of hurdles:1) The analysis software in use may

"Don't expect comfort inside glass boxes in hot climates" are words from The ASHRAE Guide for Buildings in Hot and Humid Climates. Shading the roof and other badly oriented surfaces is imperative, but you have to address the fact that heat is rapidly entering the space due to the high thermal conductance of glass. The obvious recommendation is to increase the percentage of solid to glass

I'm just going to throw this out there; someone needs to own every analysis model and develop a method for keeping it current.Working with Revit, my belief is that the Architect should own the daylighting model which can be exported either through room objects or BIM geometry. Room objects are the best candidate in that they often describe only those areas that need to be analyzed. IES

Imagine having a simple chart that can allow you to make nearly every orientation design decision with the confidence of comparing numbers. Some might call it cheating to not fully investigate all of the factors involved, but if you don't have the capability to conduct a full thermal analysis here is a quick way to make informed decisions.But there will always be designers who simply avoid

The first fundamental of an iterative Green BIM process is the necessity for integrated 3D design. Alternative workflows will ultimately lead to a clumsy process of redrawing, working backwards, and constantly fighting deadlines with an inefficient use of resources. To be very clear about what I'm saying, a design or changes to a design can begin with a sketch, but every move thereafter must
