SMART BUILDINGS: The Benefits of BIM Technology

The Technology

“SMART Building Technology” or Building Information Modeling (BIM) is a collection of software and hardware products and services that use data and information about a building and its environment to automatically optimize the building’s operation and maintenance according to user requirements. Pioneered by some of technology’s most progressive and innovative leaders; Cisco Systems, Hewlett Packard, Johnson Controls and Siemens Corporation, SMART Building Technology takes many different forms but is ultimately enabled by the availability of low cost actuators , sensors and proliferation of data networking across an urban environment. A SMART building has the infrastructure necessary to identify and correct its own sub-optimal operation, adapt to changes in user requirements and interact with its occupants.

Energy Efficiency: More accurate monitoring and controls of energy intensive systems like HVAC and lighting help keep inefficiencies in check. The careful measurement and monitoring of energy use for the purpose of reducing consumption is the hallmark of Green and SMART buildings. Owners/tenants can expect to have a reduced effect on the environment.

Fast, Effective Service: BIM technology gives owners the tools needed to better serve guest, occupants and students. Recent innovations allow facility professionals to access building systems via secure intranet, making it easier to answer questions and monitor building performance. Problems are identified early and solved immediately.

Siemens Air Velocity Sensor

Simplified Property Management:  Maintenance crews will no longer take pressure readings, adjust valves by hand or search through stacks of blueprints and schematics to find information.  Adjustments are made and information obtained from the network operation center, the 3D model, with just a few simple keystrokes. The result is a streamlined facility management operation.

Enhanced Life Safety and Security: Innovations in fire response allow other building systems to react to alarms: exhaust dampeners open, the IP and paging systems issue instructions of occupants, the access control systems unlock doors for evacuation and access to emergency responders, CCTV cameras provide emergency responders with a view of the environment.

Siemens Humidity
Sensor

Indoor Air Quality: BIM technology provides building owners/operators with the ability to monitor Indoor Air Quality (IAQ) and take appropriate actions to minimize the negative effects of contaminants, humidity and pollutants on museum artifacts and objects.

So Far...
The post on this blog have focused heavily on the documentation of historic buildings, the creation of a 3D model of the History Park and possible uses for the completed 3D model. Though one of  the early stated goals of this project was the documentation of the museum's 50,000+ artifacts, there hasn't been much discussion about the processes we intend to employ. In fact, artifact documentation will be the most challenging aspect of the entire project.  The unique nature of this collection requires some innovative strategies for digital documentation and exhibition.

Given NVentum's affinity for and expertise in laser scanning technology, one would assume that the majority of the documentation would be done with lasers of some type. What makes this project so unique is the diversity, size and scope of the History San Jose collection. This unique collection requires a plan that integrates a variety of techniques and technologies to properly document the museum's artifacts and property. The museum's collection varies from electronic devices to clothing; from paintings and manuscripts to automobiles and kitchen utensils. Laser scanning technology may be appropriate for the documentation of some artifacts, however multiple approaches and techniques will be necessary to complete the task at hand.
The vast majority of the museum's artifacts are stored in the museum's collection center, unavailable for exhibition and unseen by the public. A major objective of this project is to enable the public to view these historic items. The museum's ability to display and exhibit these artifacts is limited by the amount of exhibit

space available on the property.  A virtual, online exhibition has no such limitations. The 3D documentation of these artifacts will provide the foundation for future online exhibits that would otherwise occupy space in a warehouse, away from view of the public.
The documentation of the historic buildings and grounds is a relatively simple task in comparison to documenting the museum's artifacts. Laser scanning technology has been developed specifically for construction, design and surveying applications. The creation of a 3D model of the park and its' buildings won't be a first. If you go to YouTube, you can can see 3D laser scans of all types. The difference in this project can be found in its "layers". Starting with comprehensive documentation, this project includes BIM, asset management, exhibition,  marketing, preservation and sales.

The documentation of the History Museum's artifacts presents several inherent problems. As mentioned in previous blog posts, laser scanning technology has limitations when it comes to artifacts with extremely high levels of reflectivity or extremely low levels of reflectivity. Given these facts, we have pinpointed some items of concern within the museum collection. Discussions about the type of techniques available and possible answers/solutions to new challenges have begun in detail. If we choose to use laser scanners, how will we address the highly reflective chrome handle bars of the museum's antique Harley Davidson Motorcycles? When documenting antique clothing, is there a benefit in laser scanning vs HD photography? There are dozens of questions that immediately come to mind when discussing the documentation of artifacts.
