Building ASHRAE’s Sustainable Showcase ASHRAE’s goal in renovating its existing Headquarters was to provide a healthy and productive environment for staff and to showcase ASHRAE technology, while demonstrating the Society’s commitment to sustainability. The building was designed as a “Living Lab” and demonstration model for our membership in advancing the arts and sciences of HVAC&R while serving the needs of current ASHRAE staff, taking growth into account. In 2005, the ASHRAE Board of Directors voted to adopt sustainability as the central theme for the Strategic Plan. Demonstrating that commitment to sustainability, the Board decided to renovate and expand the existing headquarters building. At the same time, a target was set for achieving LEED-EB Gold and LEED-NC 2.2 designation for the renovated building. The Ad Hoc Committee assembled a great professional and volunteer support team. On the professional side, a team was assembled including RWH as the architects on the project, Johnson & Spellman Associates as the mechanical and electrical engineers, Gay Construction as the construction managers and CxGBS as the Commissioning agents. A Technical Advisory Committee was established with subject matter experts from our vast volunteer base in areas such as architecture, mechanical systems, lighting, controls, sustainability, IAQ, energy, and operation and maintenance. Goals included maximizing day lighting by minimizing perimeter offices and use of modular furniture; following the guidelines in the Advanced Energy Design Guide for Small Office Buildings; providing 30 percent higher ventilation than required by ASHRAE Standard 62.1-2004, Ventilation and Indoor Air Quality; reducing energy use by 30 percent as compared to ASHRAE Standard 90.1-2004, Energy Standard for Buildings Except Low-Rise Residential; provide renewable energy through solar photovoltaic to meet 10 percent of the annual peak electrical demand of the building; and providing building performance and system data that will interface through ASHRAE.org. Some of the key technical parameters of the final project include: • A fully dedicated roof mounted DOAS system proving 6,000 cfm of outside air and incorporating dual sage air to air heat recovery desiccant heat wheels, variablespeed outside air and exhaust air fans, dx cooling coils and MERV 13 air filters • Level 1 of the building and the Learning Center are conditioned using variable refrigerant flow inverter driven, two-stage outdoor dx heat pumps and ducted fan coil units operating on HFC 410A • Level 2 of the building is conditioned using two-stage, 27 EER variable-speed ground source heat pumps operating with a geothermal field comprising 10–400 feet deep wells and a closed loop piping system • High-efficiency lighting operates at 25% to 35% lower power level with occupancy sensor control • A roof-mounted 20 KW photo-voltaic electrical power generating array • A water-efficient plumbing system includes high-efficiency low-flow toilets, waterless urinals, and solar water preheat of domestic hot water • Storm water retention capacity provides harvested storm water for irrigation • A direct digital control system provides overall control, with web browser interface has wiring and sensors and manipulation capability, web access, and a meteorological monitoring station to monitor the building. The system provides sufficient
