Altura team members have been working with Broadcom Ltd (formerly Broadcom Corporation) since 2010 to help improve the company’s CSR performance, which has included managing the company’s annual greenhouse gas inventory, CDP survey responses and annual GRI sustainability reporting. Altura is also responsible for managing Broadcom’s global utility management program, which encompasses all building assets in the Broadcom Ltd. portfolio.
Global Energy Management Program: Altura helped develop and implement a global utility management program at Broadcom that reduced electricity use by 11,128 MWH, water consumption by 7.3 million gallons, landfilled waste by 176 short tons, CO2e emissions by 4,489 MT and annual utility spend by US$1.5M. Through active stakeholder engagement, Altura empowers Broadcom employees to drive change and strengthen the development and implementation of climate change strategies, reporting methodologies, and emission reduction programs. At one facility alone, an energy efficiency audit identified an estimated $400,000 in annual savings.
New Irvine Campus Commissioning: Altura was responsible for leading an analytics-driven commissioning process at Broadcom’s new Irvine headquarters. Phase 1 is comprised of five buildings ranging from 1 to 5 stories and a total of ~1.1 million gross square feet. The commissioning services scope included building HVAC&R systems and controls, lighting systems and controls, water heating systems and controls, emergency power systems, compressed dry air, and irrigation systems. Services also satisfied LEED v2009 for New Construction and CALGreen 2013 requirements.
San Jose Facility Retro-Commissioning: As a first phase in a retro-commissioning assignment at Broadcom’s San Jose Campus, Altura conducted an ASHRAE Level 2 energy audit for the 470,000 SF facility including data centers, laboratories, and commercial office space. As a result of the audit, Altura identified nearly $560k in annual savings at the complex, representing nearly 10% energy savings and GHG reductions of 1,730 metric tons, with an aggregate simple payback of less than 3 years for identified energy conservation measures. Building on this plan, Altura developed bid documents and managed the bidding process for the first phase of implementation, representing nearly $400k in capital upgrades. Altura coordinated implementation and supporting the project with SkySpark-integrated retro-commissioning to ensure projected savings targets are met and exceeded. The project was completed in 2015.
Altura subsequently deployed the SkySpark data analytics platform to identify further controls enhancements and to track the performance of implemented efficiency measures. The project spanned two campuses in the San Jose area and leveraged 3 deployments of the Johnson Metasys system (with some Trane Tracer integration). The project team also developed a whole building controls retrofit scope of work to add an additional building to the Johnson Controls System, including specifying the use of wireless communicating thermostats, new rooftop unit integrations, and variable speed drives across multiple pieces of equipment. The data were then integrated into SkySpark for monitoring and validation of contractor work, which ensured the projects delivered on the expected energy savings of more than $500k per year. Savings have since been validated with whole building energy use data utilizing an IPMVP Option C approach.
New San Jose Campus Commissioning: Altura is serving as project manager for an analytics-driven commissioning project at Broadcom’s new 544,000 SF facility (known as CMK LLC at Innovation Place), which includes data centers, laboratories, and commercial office space. The scope of the project includes all HVAC systems and controls, electrical systems, plumbing systems, and building automation system. Altura is leading the project’s integration into SkySpark, an advanced fault detection and diagnostics platform which will support the commissioning process, future TI processes, and building optimization during the first-year warranty period.
