Conrad N. Hilton Foundation
Phase I of the Conrad N. Hilton Foundation campus included a $24 million, 22,000 SF facility exceeding LEED Platinum performance standards and designed to be a net-zero energy building. Construction was complete in 2012, and systems commissioning extended through 2013. Altura team members led and oversaw the commissioning process for the facility, which included SkySpark integration to support net-zero benchmarks and performance verification. To our knowledge, this was the first ever application of SkySpark to a new construction commissioning process. Systems tested on the building include chillers, custom passive downdraft units, heat exchangers, boilers and underfloor VAV zones (in excess of 50).
Altura is engaged in the on-going optimization of the unique fan-less buoyancy driven cooling system for Phase I of the headquarters, leveraging SkySpark to proactively identify issues, verify systems performance, and facilitate ongoing training of building operators through a monitoring-based commissioning process. Altura is also directly engaged in the Measurement and Verification process for the facility, in conjunction with the design engineering team (WSP Flack and Kurtz). Altura oversaw the development of a detailed test and balance plan for this unique system, and worked to develop control strategies for minimum ventilation control. Altura also assisted with the design and selection of a comprehensive, cost-effective sub-metering program, including more than 100 individual meter points for M&V analysis.
