Make plans to participate in the Consulting-Specifying Engineer HVAC Webex for K-12 schools and colleges and universities on March 29 at 1 p.m. CST. DLR Group's Rod Oathout will share how providing cooling/heating comfort and energy efficiency in school buildings is an ongoing challenge for mechanical engineers. Emphasis on building performance and adoption of energy-efficient building codes is increasing. Designs are based on a host of variables beyond space type and understood loads including operating costs, first cost, lifecycle cost, and measurement and verification (M&V) requirements. Demand for historically typical HVAC technologies, such as variable-air-volume (VAV) and water-cooled chillers, is evolving to include a variety of systems, such as displacement ventilation, combined heat and power (CHP), geo-exchange, simultaneous heating/cooling systems, variable refrigerant flow (VRF), passive design, chilled beams, dedicated outdoor air systems, and evaporative cooling.
Panelists will describe the various heating and cooling technologies and systems, with an emphasis on comparative efficiency, and will analyze the pros and cons of heating and cooling technologies, specifically in schools. Attendees will earn one AIA CES approved LU.
