A few blocks from the High Line, the restored elevated railway bed that now sports pedestrian walkways amid a landscape of greenery, New York City’s Chelsea Green is a 14-story luxury condominium from Alfa Development.
This article examines how a building’s energy performance can be enhanced with structural thermal breaks for balcony connection. New engineered solutions can assist mid- and high-rise building project teams in complying with continuous insulation (ci) code requirements. These structural connections are especially important to address in multi-family specifications because thermal bridging for every residential unit in the structure can add up to significant heating and cooling loads.
In light of the federal government’s goal of improving the energy efficiency of new and existing buildings, model energy codes are becoming more stringent. The effort to increase energy efficiency has been further emphasized by initiatives set forth by the 2009 American Recovery and Reinvestment Act’s State Energy Program, and a congressional mandate that all states, must comply, at a minimum, with the American Society of Heating, Refrigerating, and Air-conditioning Engineers (ASHRAE) 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings, no later than October 18, 2013.
In an ideal world, a continuous layer of R-10 insulation could be installed over the entire surface of a building, resulting in an enclosure with an effective insulating value of R-10. However, such a structure would be both aesthetically unacceptable and impractical to build. Real buildings need thermally conductive framing, wall openings, and various combinations of continuous and interrupted insulation.
