Khosla Ventures: a venture capital firm run by people who listen to, analyze, and advise entrepreneurs, manages a main fund that supports early- and latestage investments and a seed fund for developing very early-stage experiments. As a firm that focuses on next-generation energy projects, new materials, mobility, the Internet and silicon technology, it was imperative that the building reflect these industries.
This high-profile office building located in Menlo Park incorporates many green technologies with the goal of LEED Gold, including geothermal wells, solar panels, and energy-saving building management systems.
WHAT ACCO DELIVERED
Water-cooled variable refrigerant flow (VRF) system. This 13,000 SF building that houses one of Silcon Valley’s most prestigious venture capital firms makes use of an innovative geothermal condenser water loop to feed 4 water-cooled condensing units and a corresponding network of 41 VRF fan coil units within the occupied building space. Ventilation air to FCU’s is preheated by a solar panel heat exchanger system. This highly efficient HVAC system is capable of yielding EER’s in excess of 20.0 due to the concept of heat pump balance, as well as through ECM motors, variable speed driven circulating pumps, and an advanced DDC control system by Automated Logic Corp.
LEED requires that an energy model validate proposed effifciencies. ACCO produced this energy model in-house which will work towards the goal of LEED Gold.
