Glenborough, LLC is a privately held, full-service real estate investment and management company focused on the acquisitions, management, leasing, and development of institutional quality commercial properties. Glenborough, LLC has offices located in San Francisco, San Mateo, Irvine, San Bernardino, San Diego, Denver, Las Vegas, Tampa, and Washington DC. Glenborough, LLC has three decades of experience in the real estate investment and management industry, and provides exceptional service across a range of investment, management, and ownership opportunities. A primary focus for Glenborough has been its energy conservation and sustainability programs. An ENERGY STAR Partner since 1999, Glenborough's management considers its commitment to energy efficiency and sustainability to be a strong statement about leadership and social responsibility, and has shown longstanding support for the development of these activities. For more than eight years, benchmarking energy performance using EPA's Portfolio Manager tool has been a key element of Glenborough's company-wide energy management program, helping the company to identify opportunities to improve energy efficiency across its portfolio. Furthermore, in 2007, Glenborough implemented an organization-wide Sustainability Program that reaches out to tenants through coordinated Sustainability Awareness training sessions and continuous updates throughout the year. Partnership with ENERGY STAR has provided Glenborough with valuable resources, ideas, and guidance, and has enabled the company to set aggressive energy management goals and to achieve superior energy performance.
Glenborough, LLC has been recognized by EPA as an ENERGY STAR Top Performer for achieving an average ENERGY STAR energy performance score of 84 across its portfolio of buildings. Glenborough was also previously recognized in 2009 for improving energy performance by more than 10 percent across its portfolio of buildings compared to a 2001 baseline. Glenborough's proactive energy management strategy is helping the company to save over $1,500,000 in energy costs annually. Some successful energy efficiency measures instituted across Glenborough's portfolio include: increasing management's focus on existing HVAC system calibration; upgrading systems and performing retrofits to improve system efficiencies; implementing lighting upgrades, including the installation of motion sensors; installing variable speed drives; utilizing energy management systems; and using cutting-edge technologies in chiller control and optimization. One prime example of the company's energy efficiency measures involves the retrofitting of two chillers from R11 units to non-CFC, R134a machines that incorporate an all variable speed drive (VSD) chiller system. At select buildings across the country, Glenborough is partnering with EnerNOC using its energy analytics platform and EfficiencySMART Insight process towards ongoing load management strategies, enabling Glenborough's buildings to be smart grid compatible. Glenborough has demonstrated continuous improvement in its already impressive energy performance, and looks forward to targeting even greater improvements across its portfolio. Compared to a 2001 baseline, Glenborough is currently preventing the annual emissions of more than 400 metric tons of carbon dioxide equivalent, which is equal to the carbon sequestered by more than 10,000 tree seedlings planted and grown for 10 years. Glenborough's newest initiative involves utilizing real-time energy data in order to minimize peak demand usage.
Among Glenborough's building-specific accomplishments is the landmark Aventine Office Building property in La Jolla, California. The chiller retrofit at this building incorporates Turbocore compressor technology, controlled by a chiller plant optimization software application. This upgrade has improved chiller efficiency by approximately 50 percent, eliminating more than 850,000 pounds of carbon dioxide and saving more than $110,000 annually.
