LEED for New Construction and Major Renovations is a green building rating system that was designed to guide and distinguish high-performance commercial and institutional projects, with a focus on office buildings. The CCSN TELECOM BUILDING is the first building in Nevada to earn this forward-thinking LEED certification. DCSI commissioned the mechanical, life-safety and electrical systems of this project.

The Desert Living Center is the “green” jewel in the crown of the Las Vegas Springs Preserve. The Desert Living Center buildings are the first platinum LEED® (Leadership in Energy and Environmental Design) buildings in the state of Nevada. These buildings embody the Preserve’s message of sustainability.

The Desert Living Center is made up of five buildings and the surrounding gardens.

DCSI Commissions First LEED® NC Platinum-Level Project in Nevada

DCSI has commissioned the first LEED NC Platinum-level project in Nevada: The Desert Living Center at the Las Vegas Springs Preserve. The designation, the highest a building can receive from the U.S. Green Building Council, requires that a majority of required building materials be recycled, re-used or recyclable, among other things.

The $250 million Las Vegas Springs Preserve aims to be Nevada's first LEED Platinum project. It will provide space for the Nevada State Museum, Visitor's Center and the Desert Living Center interspersed among restored wetlands. It will include more than 176,000 square feet of museums, educational galleries and interactive exhibits. It will eventually include the 79,000-square-foot Nevada State Museum that is expected to open in 2009.

Unique Aspects of this Project:

It will be the first attraction in the U.S. to achieve LEED (Leadership in Energy and Environmental Design) Platinum Certification.

It is the largest commercial straw-bale project in the U.S.

Solar panels on site will generate enough solar energy to power approximately 70 percent of the Preserve attraction.

The Preserve is home to more than 250 species of wildlife.

Water on site will be filtered and reused to irrigate plants and flush toilets at the Preserve.

SCOPE OF WORK: DCSi will coordinate the activities associated with quality assurance as related to the environmental systems to confirm that the performance meets the design intent, the manufacturer’s requirements and the operational requirements of the system holistically. The following briefly describes an itemization of how this might be achieved.

Witness initial opening of equipment shipped back to the Loadtec facility located in Las Vegas, Nevada

Observe and report the condition of the Loadbank as received at the Loadtec facility

Perform digital photography to record condition of received Loadbank

Investigate root cause of damage

Review the electrical one-line diagram, including over-current protective devices

Review trending data recorded on equipment mounted monitor

Review the design, materials, workmanship of Loadbank with emphasis on clearances of live parts/connections

Investigate report of damaged and corrected Loadbank enclosure lighting wiring

Review the heat/flash pattern resulting from equipment damage

Conduct fault analysis related to Loadbank equipment damage

Attend meetings as required

Perform Loadbank damage assessment

Compile and submit a final report

SCOPE OF WORK : DCSi will systematically record phase currents, voltages and total KVA for the one specified location for a period of seven days.

Install and record a Power/Demand Analyzer to measure and record the current of each phase in RMS amperes and the total KVA during a period of seven consecutive days, at one location. The possible locations are as follows:

The above locations were selected as these transformers serve the Smart Switch 6000s that are experiencing the problematic switching issues reported.

Coordinate our activities with the client and occupant for the facilities (locations as specified).

DCSi will provide an electrical data recording report with the RMS current and KVA demand versus time for each day of the recording and will include a hard copy of the measurements recorded at each interval in order to verify the loading of the existing circuits indicated above. (Compile all recorded data (as indicated above) and submit to client upon completion.)
