GreenspaceLive Impact

To achieve significant and deep interventions required to meet the challenging targets necessitates a decision-making process that evaluates fabric and technology solutions at an early stage in the design process. The interaction between all the different elements can only be evaluated by dynamic simulation which utilises the laws of physics to simulate how an asset should perform.

Projects using energy modelling generally exceed the energy reduction targets and tend to encourage good sustainable design where passive design strategies make bigger impact to curb energy use are evaluated and incorporated to achieve demanding targets. Energy modelling from easily obtained data also helps design teams consider all the elements and their likely impact on carbon use where targets can be set and regularly checked against progress.

To encourage widespread use of dynamic simulation an on-line web and cloud-based approach is offered by GSL which is affordable and much more accessible to the construction industry. With the need for significant investment to achieve energy efficiency targets new initiatives such as Energy Performance Contracting will require the detailed evaluation of the most cost-effective solutions so that these contacts are well prepared, and risks minimised.

Rapid dynamic simulation would benefit a range of building professionals including designers, technologists, fabric specialists/manufactures, energy engineers, contractors and developers.

All investment decisions require good planning and risk informed decision making which in turn requires evaluation of fabric/technology solutions long before and capital expenditure takes place. Optimising the impact of solutions can be evaluated to maximise the rate of return on investment.

Dynamic simulation tools that are accessible and affordable will enable the construction industry to face the challenge of deep interventions and support this `new` business opportunity where 98% of the problem has already been built. In the next ten years a large proportion of existing buildings will require some form of intervention and support with decision making tools of this nature will enable the industry to take technical and investment decisions that will support this intervention opportunity.

A web-based approach allows for on line collaboration where all professionals involved in the projects can communicate and share data virtually which has a resulting productivity gain.

First design with GreenspaceLive

At the early building design stage energy modelling can assist with the process of evaluating all the options which can contribute to a high-performance building.

It is now recognised that integrating energy modelling into the building professional’s workflow will result in buildings that can meet high performance expectations.

Early concepts that introduce passive design options and methods to reduce energy requirements can form part of an exercise to determine energy targets achieved by an iterative design process where the model can be modified and tested to maximise performance.

The first Sketchup model can be transformed to gModeller and ready for either deep dynamic simulation gEnergy or energy code compliance assessment programmes.

gModeller enables the export and import of gbxml models.

The new version of gModeller V2.2.2 is now available on line with improved performance!

Early results allow for design refinements where decisions are based on sound technical analysis and good risk informed decision making

Bringing DEEP DYNAMIC SIMULATION to the early stage design process allows the building professional to evaluate numerous design options with the web enabled gEnergy giving the full power of EnergyPlus – the global standard.

Take the early opportunities to improve value!

gModellers Automated Functionality

Are you aware that it’s even easier to make gbXML and IDF models with gModeller with our automated texture and spacing functionality?

Once you’ve built your model, you can easily automatically apply your surfaces by clicking “Auto Apply Surfaces” shown below.


Once this has completed, you can review your model and, if any incorrect surfaces have been applied, overwrite them with the correct surface.

You can space your model automatically by clicking the “Auto Apply Spaces” button shown below.


This will space your model using our latest spacing technology. Count the rooms against your space count, you should find that they are both equal!


If you make changes to your model, you can update the model without resurfacing and respacing! Simply use the “Sync Geometry” button below!



If you have any queries or problems, contact GreenspaceLive via our webpage.

Introducing gModeller 1.9.5


GreenspaceLive are proud to reveal our latest version of gModeller: gModeller 1.9.5!

We’ve made a number of improvements, fixes and new additions to gModeller based on user feedback to make the process of creating gbXML and IDF models from SketchUp with ease.

gModeller 1.9.5 Change Log:

– Sync Geometry has been improved. This means if you make changes to your model after you have textured it, such as moving windows or doors, you can use Sync Geometry to update the  gModeller gbXML file without retexturing.

– A button for Sync Geometry has been added to the gModeller toolbar.

– Space Selection has been improved to detect fully enclosed spaces, including more abnormal shapes and designs.

– Join Close Points has been added. This closes small gaps (under 1cm) within your model that may have occured during the modelling process. This is available in the Plugin Menu within SketchUp.

– Repair Model feature has been added. Repair Model will take your current model, save it and re-create it, eliminating any additional surfaces and points in your model. This is available in the Plugin Menu within SketchUp.

– ‘Paint Detected Spaces‘ runs the space detection and draws the floor of every detected space yellow, making any problem spaces visible in green. This is available in the Plugin Menu within SketchUp.

– Export function changed.

– Stability improved.

Available Now!

gModeller 1.9.5 is available now at www.greenspacelive.com

Create a new project – call this “Quick Start” or “Getting Started”




Click “Import IDF” from the options at the top of the gEnergy screen. Select ‘Bessemer Grange School’ from the dropdown menu. You can also choose your own IDF files to upload to gEnergy from here. Don’t worry about file versions, gEnergy will automatically make your IDF compatible with the latest version of EnergyPlus that is required. Once you’ve chosen your file, click Upload File.

At this point, you can make any changes you wish to make to the model, if desired. To do this, click a ‘Group’ on the left, this will open the group’s objects in the Object window. To edit an Object’s properties, simply left click the object in the Object list and edit it in the EnergyPlus Object Form located at the bottom right.


However, for this quick demonstration, you want to just click “Run Simulation”. The message console will appear and start running the gEnergy simulation. You can view your simulations progress in this window.


When this is completed, click on Reporting: Charts.




Here are some default charts displayed. You can add your own charts from the results by pressing “Add Chart” and then selecting your parameters from the list and moving them to the right. You can export any of your charts as a CSV file for Microsoft Excel by pressing “Download CSV”. You can also view your data as an HTML web file, detailing information from your simulation. You can view this by pressing “Reporting: HTML”



You now know the basics of gEnergy, why not add your own IDF and try it for yourself?

Introducing gEnergy and our Beta test program!

gEnergy brings building simulation to the cloud, enabling architects, engineers and building owners to design and operate energy and resource efficient 21st century buildings. A new addition to the greenspaceLive gTools suite, gEnergy, is a powerful building information and energy modelling tool using the EnergyPlus platform. New-build and retrofit modelling scenarios can be rapidly explored, minimising construction and operational stage problems, raising design-team productivity and lowering cost of build and ownership.

gEnergy enables creation of new EnergyPlus models and imports SketchUp, Revit, gbXML and IDF models. Over 600 building objects, constructions and HVAC systems are supported in our easy to use Web interface.

Learn more about gEnergy…

Beginning today, the gEnergy Beta Program will give existing subscribers access to gEnergy before our general release. Our goals with this program are to expand our pool of testers and gain feedback across a more diverse set of devices. Just by using gEnergy and reporting issues, beta testers will be able to help us improve performance on a wide variety of browsers and devices we may have otherwise been unable to test at scale.

This will give greenspaceLive the opportunity to eliminate any issues and identify the diversity of our user base to test our future gEnergy builds so, when we release to the open market, everyone has a better experience. Whether you use Firefox, Chrome or Internet Explorer, more complete testing coverage gives us the opportunity to make sure more people can access a stable high-performance platform.

Anyone with an active subscription can join the beta program. You can access gEnergy through its portal on our website. We ask that you use gEnergy like you would normally use an EnergyPlus editor, but that you submit a report whenever you encounter a bug or other issue. Because gEnergy will be a Beta build, it will have features that may still be in progress and as a result, be less stable than you may be accustomed to. Feedback on stability, as well as any other performance issues you experience, is crucial and deeply appreciated.

To join our Beta program, follow these steps:

1)      Register on our website (if you do not already have account)

2)      Visit the gEnergy page and log in

3)     Submit feedback through the webform (at the top right of the program) in gEnergy

4)      We’ll contact you with a survey during the beta program, we would be greatful if you completed it

If you have any questions about our gEnergy beta program, or regarding the software, contact us! We’ll be more than happy to answer your questions.
