Session Outline 1.Dispel some popular myths about R values 2.Compare popular wall systems 3.Detailed look at wall system heat flow 4.ORNL study of mass walls in a model house 5.Proposed mass house for optimum energy performance 6.School energy performance study at University of Louisville
{"Image DocumentName": "1. True U and R Values in Building Walls", "Image ImageDescription": "Introduction \u2013 The LEED\u00ae Mandate \u2013 ever-decreasing energy demand for buildings. We examine popular wall systems for ACTUAL heat flow. All include air and moisture barriers. Alternates for glazing area considered. Mass not included in calculations, but will benefit. eQUEST or Simergy lets you quickly study the effects of different wall systems on whole building energy performance. Occupancy types are critical for effective evaluation of building performance. Energy demands vary widely: Introduction \u2013 The LEED\u00ae Mandate \u2013 ever-decreasing energy demand for buildings. First we examine popular wall systems to see what their ACTUAL heat transmission is. All systems include effective air and moisture barriers. Alternates for glazing area are considered. The effect of mass is included in heat flow calculations. I challenge you to use the DOE\u2019s FREE eQUEST or Simergy whole building analysis to study the effectiveness of different wall systems in whole building energy performance. Occupancy types are critical for effective evaluation of building performance. Energy demands vary widely: Assembly. Office. Schools. Multifamily residences. Restaurants. Shopping malls. Small retail. Big box stores.
