Green Tech Feasibility Report in NYC Sold Out!


April 10, 2013 - 8:00 am to 9:00 am - Hosted by Cushman & Wakefield


The use of geothermal technology for space conditioning in New York City has grown in recent years, and as the first city agency to utilize these systems, the NYC Department of Design and Construction has first hand experience with both the benefits and challenges.  
This presentation will discuss how geothermal systems work, the three basic types, and the advantages and disadvantages of each.  An overview of the City’s complex geology will highlight how subsurface conditions affect system selection and design.  Considerations from building loads to construction activities will also be discussed along with O&M requirements that lead to a successful installation. 
DDC case studies will illustrate how they were employed in various buildings and sites.  Some of the challenges encountered and the available options in resolving them will also be discussed. DDC’s new manual provides a how-to-guide for assessing the City’s geology and how GHP systems can be integrated into sustainable building projects.  A limited number of manuals will be available afterwards.
