Sustainable Systems at Town Hall
In an effort to improve the sustainability of Town Hall, several upgrades have been made to reduce resource consumption and generate greater efficiencies.
Server computers are important to computer networks because they host files and other applications. These computers also consume significant amounts of electricity and generate lots of heat. In 2013, the Town eliminated the need for seven servers using a new technology called virtualization. Under the concept of virtualization, specialized software is used to create multiple "virtual" machines, allowing the work of several physical servers to be consolidated into one. As a result, the Town Hall server electricity demand has been reduced by an estimated 7 kilowatt hours, with additional energy savings derived from a lower cooling demand for the IT server room. This project was designed and implemented by the IT division of the Business Management Department.
Energy Management System
As part of a 2010 heating, ventilation and air conditioning (HVAC) system replacement project, an energy management system was installed. The energy management system offers automated control and monitoring of the HVAC system. Computer monitoring allows building technicians to improve self-diagnostics and regular optimization of the equipment. This project was implemented by the Facilities division of the Public Works Department.
In 2010, all toilets in Town Hall were retrofitted with a water-saving, dual flush valve. Pulling the handle up to flush liquids will use approximately 30% less water. Over the course of a year, this action could save about 1,000 gallons per fixture or as many as 18,000 gallons throughout Town Hall. This project was implemented by the Facilities division of the Public Works Department.
To lower electricity use from indoor and outdoor lighting, the Town has installed both energy efficient fixtures as well as complementary sensing technology that can detect motion or light. In 2010, office and conference room lighting was improved by switching out less efficient fluorescent tube lighting or incandescent bulbs for lower wattage alternatives. In most cases, the alternatives were higher efficiency tube lights (T-8 or T-5) and compact fluorescent bulbs (CFLs). As a complement to these fixture upgrades, in 2012 the Town installed motion sensors designed to turn off lights when offices or rooms are unoccupied. The Town has also experimented with light emitting diode (LED) technology. In 2012, 150 watt high pressure sodium lights were replaced with 41 watt LED lights in the Town Hall parking deck. This project was implemented by the Facilities division of the Public Works Department in concert with the Office of Sustainability. Funding for the sensing technology and parking deck lighting was made possible through a grant from the U.S. Department of Energy's Energy Efficiency and Conservation Block Grant, an American Recovery and Reinvestment Act (ARRA) program.
To minimize staff vehicle trips and reduce fuel consumption, the Town has installed videoconference equipment in most major Town facilities (Town Hall, Public Works, Transit, Parks & Recreation and Police). Videoconference equipment allows Town employees to conduct virtual meetings in real time using a camera and television screen. In addition to the benefits derived from less vehicle travel, videoconference technology also eliminates travel time between facilities. This project was designed and implemented by the IT division of the Business Management Department in concert with the Office of Sustainability. Funding for the videoconference equipment was made possible through a grant from the U.S. Department of Energy's Energy Efficiency and Conservation Block Grant, an American Recovery and Reinvestment Act (ARRA) program.
