Takeaway: Autodesk FormIt for iOS is an App that incorporates building performance analysis from the very earliest stages of the design process. Validation of the Energy Cost Range involved more than 171,000 energy simulations, which were carefully reviewed by our QA and building science expert’s team.
As you progress with your sketch by defining a location, building size, and/or building use type, the energy cost range is narrowed, based upon these inputs.
The data behind FormIt’s Energy Cost Range results comes from an Autodesk Green Building Studio (GBS) dataset of more than 171,000 energy simulations. These pre-computed DOE2.2 whole building energy simulations cover 16 climate locations, representative of all worldwide climates, 34 building type functions, 4 conceptual building sizes and forms, and a wide range of energy efficiency measures covered by 37 parameters (representing new construction standards and beyond) . Visit our help topic for more details of the simulation parameters: Alternative Runs (Details). The utility costs currently assume $0.10 USD/kWh of electricity and $1.00 USD/therm of fuel.
Lighting Controls (Daylighting) with all Window Glass Parameters

Lighting Controls (Daylighting) with all Skylight Glass Parameters
4 + daylighting with baseline skylight glass
Either off or on (baseline assumes off)
Details of the parameters are outlined in this Help Topic: Alternative Runs (Details). All baseline properties and values are based upon building type function, building size and height, and project location. These baseline assumptions are based upon a number of energy standards and building surveys. More information about the assumptions used for baselines can be found in this Help Topic: Assumptions and Default Values in GBS.
Tell us what you think: We encourage everyone to download FormIt and try it out. Please post your comments and questions on our Building Performance Analysis Community pages. Our Building Performance Analysis (BPA) team regularly monitors the community forums and will respond to your postings.
Today we are announcing the immediate availability of the Formit Weather Station service on iPad. Weather Stations provide historical weather data in a form that extends beyond the desktop. Weather Stations allow you to learn all sorts of things about the climate of your project site including:
• Ad hoc energy cost range; explore micro-climates by adjusting you location or dropping pins
• Check temperature statistics
• Investigate prevailing winds at your project location; interact with the weather data by tapping series in the legend
• Custom weather visualization; create your own weather charts in Project Solon and publish to Formit.
Ad Hoc energy cost range is based on Location, Building Type, and Building Area.
Oliver Riley, Technical Director of Energy Performance and Technology at URS needed to analyze one of Oxford University’s buildings at Linacre College. In this video Oliver describes how URS, a 54,000+ firm with offices in nearly 50 counties, used Autodesk technology to capture the building geometry with photogrammetry and conduct various energy and wind analyses in Autodesk’s Project Vasari. This workflow is better known as Autodesk’s Rapid Energy Modeling (REM). It’s pretty cool!
This project incorporates energy analysis, structural design, tradition, and innovation into a retrofit of a community schoolhouse. The student team set out to revitalize the local schoolhouse that had been damaged from recent natural disasters and needed an energy retrofit as part of an older, less efficient building stock. They used analysis throughout their design process to inform their design decisions to improve energy use and return the school to the community as a symbol of the Italian village’s identity.
This project by Russian students demonstrates a rigorous and thoughtful design process that balances energy efficiency and aesthetic considerations. The team did whole building energy analysis and other performance studies to improve the massing, orientation, and constructions of a conceptual mixed use high-rise building.
Create your own dashboards for Energy Analyis for Revit...
Project Solon Dashboards for Autodesk Revit is based on new technology now available in Revit. Now you can personalize the building performance analysis experience in Revit by defining a dashboard with charts and results that are important to you. The central web-based Solon management environment allows you to create charts and configure dashboards for all of your company Revit users from a central collaboration environment in Green Building Studio.
Project Solon Dashboards for Revit is an Autodesk Labs discussion project for existing technology to customize the display of your energy analysis results in Revit. Though this feature has been release to the public, we have not publicized it widely so that we can share it first with the Labs community. We created this project on Autodesk Labs to give you an easy starting point to learn how to manage your custom dashboards and to provide you a way to give us feedback and get personalized help using this new feature.

Who is this for: Building industry stakeholders interested in the emerging landscape of zero energy buildings in the United States and abroad.
Author: Jonathan Rowe, Zero Energy Buildings Program Manager, Autodesk Sustainability Solutions
Article: Earlier this year, the New Buildings Institute released a report that provides a snapshot into the evolving landscape of net-zero energy buildings in the United States. While the number of verified projects (those that have proven success through utility bills) is still low, over a hundred emerging projects have NZE in their sights. But targeting net-zero and achieving it are two different things, it turns out.
It’s not uncommon for a team to find out once a project is built that assumptions were way off for things like behavioral patterns, quality of construction, and the kinds or amount of equipment being plugged in to the walls. Even with the best predictive modeling tools available, net zero frequently requires tweaks during occupancy to make sure things are on track.
The compelling thing these projects demonstrate is that NZE, for the most part, is achievable without a lot of fancy bells and whistles. Off-the-shelf technology usually gets the job done fine. The innovative aspect has more to do with how teams of experts collaborate synergistically across disciplines to create buildings that are hyper-efficient, but delivered to owners at costs that don’t completely break the bank.
Last summer I wrote about how the education sector was leading the way with net-zero energy buildings. They account for roughly a third of the projects listed in NBI’s 2014 market scan, and a few university projects are muscling to outdo each other size-wise. Not to be left out, some in the private sector are getting in on the one-upmanship too.
Last month LPL Financial boasted its new 13-story, 415,000-square-foot headquarters as the nation's largest net-zero energy building. But depending on how you define net-zero energy, this project can be a bit controversial. That’s because in terms of energy demand per square foot, LPL is only marginally better than its peers (whereas most NZEBs implement deep energy saving strategies as a first step before focusing on renewables). And while most NZEBs use solar photovoltaic panels to offset energy consumption, the LPL project relies on three fuel cells that convert natural gas into electricity. The natural gas is offset through purchases of biogas from landfills and wastewater treatment plants. It’s a creative approach to carbon neutrality, but not one that fully jives with the building industry’s common definitions for net-zero energy.
One thing is for sure: net-zero energy buildings make a statement. And some organizations use them to demonstrate their commitment to sustainability and their competitiveness in a market where owners are coming to expect high performance buildings outright.
In Jakarta, a state-owned energy company hired architects Skidmore, Owings & Merrill to design the world’s first net-zero energy skyscraper. Slated for completion in 2020, the Pertamina Energy Tower is meant to be a symbol of Indonesia's commitment to sustainable development. And at 99 stories high, it dwarfs the LPL Tower. It’s not the first time SOM went down this path. Despite best intentions, the Pearl River Tower project never fully realized its ambitions to achieve net-zero energy. Talk about getting a second chance.
On a smaller scale—and a bit closer to home—DPR Construction announced their new San Francisco office will be net-zero energy certified by the Living Future Institute. This isn’t new territory for DPR. Over the past few years their San Diego and Phoenix offices made headlines for achieving similar feats. Seeing the tides shift towards a future where NZE becomes the norm, DPR are playing it smart by steadily building a portfolio of their own NZE projects, which serve as both learning opportunities and competitive marketing collateral to help win jobs.
The markup in first cost was found to be between 1-12% for energy conservation measures, with premiums as high as 20% for renovation projects. Owners with sufficient appetite for tax credits had the highest return on their energy efficiency investment dollars, 30% when taking full benefit of the federal solar Investment Tax Credit and D.C.’s Solar Renewable Energy Credit.
NBI’s analysis also found that, when considered in isolation, large building types common in D.C.’s city center are unlikely to achieve net-zero energy. Climactic considerations, solar availability, and roof area are distinct limitations to achieving NZE in dense urban areas. Technology advancements (i.e. PV panels with higher energy output) and scale jumping (think zero energy districts instead of just one-off buildings) are needed to move past these constraints.
The pace of industry progress delivering NZEBs seems to be picking up, but there’s still much to learn. Consider tuning in to an ongoing series of monthly webinars tackling various topics in this space. The next session, scheduled for May 28, will explore the new paradigm needed for creating ultra-efficient buildings at scale.
Who is this for: Anyone interested in energy analysis using Revit.
Takeaway:Autodesk Green Building Studio (GBS) has just released the Beta version of Analysis Application Dashboard in Project Solon: You can now author your Revit model once and deliver energy analysis results to your software application, web, and mobile device. Project Solon delivers responsive results designs for your energy analysis, with customized dynamic charts of energy results.
What does it do? The Analysis Application Dashboard feature in Project Solon enables you to customize how you review, analyze, and communicate the energy analysis results of your Revit 2014 and Revit 2015 projects through the use of configurable analysis charts (Widgets) and collections of the widgets (Dashboards).
Project Solon has now been integrated in Revit and includes an expanded set of result type Widgets. With this latest release you can configure five different categories of result-types: Energy Use; Heating Loads; Cooling Loads; Dry Bulb Temperature data; and Wind Speed and Direction data.
For each result-type, multiple configurations (i.e. results by month or annual time periods, sums or breakdowns of energy use, etc.) and chart types are available; allowing you to create effective and easy-to-understand results of your energy analysis. Refer to our Help Topic: Managing Solon Dashboards.
Try it now: (from the GBS Classic page, click Project Solon).

Who is this for: Architects, lighting designers, engineers, LEED consultants. Anyone interested in daylighting design.
Author: David Scheer, AIA - Archtiect, Product Owner for Buidling Performance Analysis, and Project Manager for daylighting analysis.
Announcement: We are very excited to announce another upgrade to Light Analysis extension for Revit (formerly Revit Daylighting Analysis (RDA) for LEED). The new version was posted to the Autodesk Labs site on Thursday, March 27.
This technology preview will offer free analysis runs until the plugin expires on April 30.
We are also asking for input on the tool through a short user survey. Your input will drive out next round of development work.
You can now select one or more floors to analyze, rather than the whole building. This will save analysis time, and in the future will save analysis costs.
More settings are automatically configured for each analysis request for the ‘LEED 2009 IEQc8.1 Daylighting’ 3d view, so that you will have more reliable results for common ideal settings. This includes hiding non-permanent objects like furniture and plantings, setting the phase filter to ‘Show Complete’, turn off section box, and the standard settings for Sun Only.
All automatic settings for the ‘LEED 2009 IEQc8.1 Daylighting’ 3d view can be controlled with a flag in the ‘.config’ file for RLA. This includes the settings in #2 above, among others. Now you can turn off the automatic reset of your section box if you want to limit the geometry included in the analysis, or of the electric lighting if you want to use IES files and fixtures to simulation things like SolaTubes.
You can now see the progress of analysis jobs when you click Run Analysis or Generate Results while an analysis is running. You can also cancel a job that has not completed and download partial results or preserve old results.
Error reporting and process messaging is greatly improved, and you should be able to understand what went wrong without having to call support. When that doesn’t work, we have implemented a logging capability that will create a detailed log of the RLA operations that you can send to us for debugging. To turn on this capability, set the logging flag in the ‘.config’ file and the log file will be written to C:\Autodesk\RevitDaylighting
