SketchUp: NHS Western Isles Hospital

 

GreenspaceLive is a software and consultancy shop based on the Isle of Lewis in Scotland. The company was founded in 2008 as a spin-out from the Greenspace Research, a low-carbon building and renewable energy research program at Lews Castle College, University of the Highlands and Islands. This case study about gModeller, the company’s SketchUp energy analysis plugin based on gbXML, comes to us from Donald Macaskill, Technical Manager and Energy Engineer at GreenspaceLive.

Making hospitals more energy efficient

Hospitals have unique energy consumption demands. Not only do a hospitals require lighting and heating 24 hours a day, but they also require ventilation, sterilization, laundry, food preparation and important medical equipment to be powered as well. Therefore, any improvements made to the building could drastically reduce the bills, freeing up money to be spent elsewhere.

The NHS Western Isles Trust are very proactive in trying to reduce their energy costs and carbon footprint. To determine their baseline energy consumption and carbon emissions and then to simulate a number of fabric and technology improvements to their largest building, they turned to GreenspaceLive. A hospital model and energy analysis workflow was created in Google SketchUp Pro with GreenspaceLive’s gTools suite.

 

Completed model for gModeller 

 

Project Methodology

To start, existing 2D CAD models and scanned paper drawings were shared via gWorkspace. These floor plans were then imported into Google SketchUp Pro. Once the floor plans had been imported, each floor was extruded to the correct height and dimensions. A detailed model is not required for the gModeller plugin, so the model could be simplified to single faces for walls, floors and roofs.

Once completed, attributes were added to the model using the gModeller’s customised materials, located within the Paint Bucket tool in SketchUp. Next, spaces were identified using the manual Space tool, which allowed the model to have zone specific information, such as heating, lighting and ventilation for different areas.

 

The completed gbXmL model 

 

The gbXML building information model generated by gModeller was now ready to be exported to an energy analysis engine. In this case, gEnergy was used, however, exported models can also be imported into Green Building Studio, Ecotect, Trace, DesignBuilder and others. gEnergy was initially run using the Hospital’s existing fabric and technologies to establish a baseline Energy Performance rating, subsequent analysis runs were then carried out with simulated improvements to the building, including proposed refurbishment changes, to determine the impact they would have on performance of the building.

Once gEnergy runs were completed, the model was exported to Google Earth and presented to the clients, showing gDashboard energy results on screen while touring their model.

Using the gWorkspace cloud platform, the modeling team was able to share and collaborate with the client throughout the process. Team members and client representatives were able to view, download and share files from the project, as well as view all energy runs that were undertaken.

The Results

Armed with the tools and the data, NHS Western Isles Hospital were able to model different scenarios and view the impact these changes would have. The results were dramatic – making a number of changes to the heating system, the team was able to demonstrate that the most effective change would result in over 50% energy savings, while reducing the CO2 emissions by almost 80%.

Dave Tierney, part of the Energy Team at NHS Western Isles Hospital said, “Using gTools, senior executives and staff received an overview of our carbon emissions, energy consumption and the impact changes in technology and fabric will have on our building. We can clearly see the differences in low carbon technology investment options. The results will help shape our plans for tackling carbon emissions and energy consumption in the future.”

Sketchup Ur Space

One of my new favorite sources of SketchUp inspiration and information (inspormation?) is Sketchup Ur Space. A virtual smorgasbord of articles, tips, forums and imagery, this website is sure to make you smile. There’s a monthly PDF magazine, too. The creator of Sketchup Ur Space is Debarati Nath, an India-based writer who shared some information about herself and the new site:


What am I doing in the arena of 3D?

My name is Debarati Nath and I have done a degree in Mass Communication. Well, I am not a geek, in no terms so, when I started out working with SketchUp I had only one consoling factor. I had read that SketchUp – a 3D designing tool is for every person and not for geeks alone. Indeed after working with SketchUp for some time now I have realized that even a common person can draw anything from a nail to Burj Khalifa using this designing tool. Thus my work soon became my passion and I wanted to promote the thought of SketchUp to the common masses and of course to the 3D designers all around the world.

Sketchup ur Space Magazine Gets Its Own Website

I joined the company SketchUp 4 Architect as a content writer last year. Our company was outsourced SketchUp work and we started out by launching our magazine on www.sketchup4architect.com. This magazine is published in two versions flash and pdf. Soon the magazine became immensely popular and we decided to launch an independent site for the magazine. With this idea the www.sketchup-ur-space.com was launched in March 2011.

Progress of Sketchup ur Space as an Editor

In the earlier days the magazine had to travel through troubled waters. Many hardships had to be borne. But soon the magazine earned me many friends. Our journey was made smooth thanks largely to the help and support from Jim Leggitt, Bonnie Roskes, James Hanningan, Nomer Adona, V-Ray/Chaos Group, AR Media and many other friends.

Goals That Push Us On

Our motto is same as SketchUp. We want ‘everyone to experience the power and fun of building their ideas in 3D’. Sketchup ur Space always wants to lend its helping hand to the budding SketchUp designers by providing various tutorials, tips and tricks. We want to be a piazza for all the SketchUp artists all over the world. We would like to provide them a common platform to share their views and opinion. Newbie as well as renowned SketchUp artists, geo modelers, architects and SketchUp writers are featured in our magazine. Recently Sketchup ur Space had organized a SketchUp Competition to boost the SketchUp spirit of young designers with V-Ray/Chaos Group to mark our first anniversary.

Hope that you can add more power to SketchUp and help to make it best designing tool. Connect to Sketchup ur Space Magazine and be a part of our future vision.

The Grey color for Google Places

Since Nyagoslav of Optilocal first spotted the grey pinned local results a week ago, there have been a number of other sitings of the change in the wild. There is still a fair bit of variability in the layout and arrangement indicating that Google has not yet picked a final design and they are still testing. The widespread sitings would tend to argue that ultimately the change to grey is likely.

Here are screen shots from Optilocal, LocalBusinessRockstar and LocalvisibilitySystem that capture some of the variety still presenting. Besides the grey pin, you will note that on some screen shots the pin has moved to the right. Most significant to me was the change of the Branded One Box. In moving the images to the right, Google is reducing the space given to a brand at the top of the page. We still need to see this result with SiteLinks to ascertain the full impact.
