The lab was designed with a raised floor and to accommodate approximately 300 Sun server units. The primary electrical service from the utility company is designed to serve the entire building for increased electrical service reliability at a lower energy cost. The design also includes a 4000 amp double-ended outdoor substation with 2500 kVA dry type transformer at each end for redundancy. The electrical load for the server lab is designed for 200 watts/sf, about three to four times the normal power requirement. Special wireways were designed under the raised floor providing flexibility, and to serve a variety of servers. The HVAC system is designed with N+1 redundancy on all equipment including the new floor mounted air conditioning units, chillers and chilled water pumps. Thirty 30-ton capacity floor mounted computer room air conditioning (CRAC) units were designed and located to minimize usage of data center floor space and optimize the distribution of air for proper control of temperature and relative humidity. Humidification was designed in certain CRAC units to optimize the design for operation and cost effectiveness. Additional computerized controls were installed to monitor and alarm the data center environmental conditions, equipment performance, energy consumption, equipment failure alarm, and optimize equipment energy use. Re-routing of the main water supply and converting the conventional wet fire protection system to approved Pre-Action system minimizes potential water damage to the new lab space below.

About the Reported Cost Figures The cost figures reported are supplied by the firms that submitted these projects for publication, which in most cases are the designers or builders. Whereas these sources are intimately familiar with their projects, they may not be fully aware of the owners' finally-realized and recorded costs. In some cases, costs are truly and completely accounted for, and in others they represent a near approximation of the final costs. Costs have not been adjusted for year of construction, nor has any attempt been made to make regional cost adjustments. Further, costs are not comparable on any kind of detailed standard costing model. Hence, it is possible for the cost of one building to include a steam boiler, while the cost of a comparable building might not include the boiler, if steam is being supplied from an already existing campus grid. Or, in another case, a building might include excess boiler capacity to supply steam to another building. Some submittals include fees or unusual site improvements as part of the construction costs, which others do not.
