Designing More Thermally Efficient Residential Envelopes for Northern Cold and Mixed Climates

  • Learn what a cold climate is and which energy code climate zones are predominantly cold
  • Understand heating and cooling degree-days and how they are used 
  • Compare energy code envelope requirements for mixed climate zone 4 and cold zones 5, 6 and 7
  • Review the R-value and airtightness of different insulations
  • Calculate average R-value of wood-framed assemblies with different insulations
  • Understand how to avoid increasing condensation potential as assembly R-value increases
  • Identify and overcome other shortcomings in common envelope designs
  • Learn how to insulate below-ground slabs and walls of basements and crawlspaces 
  • Understand how an air barrier is created by connecting multiple envelope barriers
  • Learn how to interpret data from a blower-door test to assess envelope airtightness
  • Review formulas used to estimate heat gain and loss or size HVAC capacities
  • See how reducing overall envelope area reduces heat conduction even with the same Rs
  • Understand why some designers choose different window SHGC based on orientation

John F. Robbins, CEM/CSDP

Energy Consultant in Morning View, KY 

Mr. Robbins has been a mostly residential designer and energy consultant since the mid-1980s who has worked on projects in midwestern and eastern states, mostly in Ohio, Indiana and Kentucky.  Whether involving new construction or retrofit, his projects aim for lower energy usage and less negative environmental impacts.  Mr. Robbins has also designed and consulted on homes which have passive solar, solar water heating and/or solar electricity, including stand-alone setups like the battery-backed PV system which has powered his office since November 2001.    
Mr. Robbins has two certifications from Association of Energy Engineers (AEE):  CEM for energy management and CSDP for sustainable development.  Mr. Robbins has received six awards from AEE since 1990 for energy and environmental achievements, including 1994 SW Ohio Energy Engineer of the Year and 2004 SW Ohio Environmental Engineer of the Year.  In 2012 AEE honored Mr. Robbins as its Region III Renewable Energy Innovator of the Year.  He was co-recipient of the 1998 Ohio Governor’s Award for Excellence in Energy Efficiency in the Education Category.   
A renewable energy advocate and user who once led the SW Ohio Alternate Energy Association (AEA) 1995-2005, Mr. Robbins encourages, assists and teaches energy users to become more hands-on and aggressive in managing and minimizing their heating, cooling and other energy usage.  He has developed and taught energy-focused continuing education courses for Great Oaks Institute in Ohio, Appalachia – Science in the Public Interest in Kentucky, Columbus (OH) Green Building Forum, Impact Management Services in Cincinnati and HalfMoon Education in Ohio, Kentucky and Indiana.

Course Title: Designing More Thermally Efficient Residential Envelopes for Northern Cold and Mixed Climates

Delivery Method: Live Online

Course Description: This two-hour course focuses on design and construction strategies to maximize the thermal efficiency of residential building envelopes in cold and mixed climates. The course will examine code requirements, demonstrate R-value calculations, discuss various tests and metrics, design strategies and more.

Learning Objectives:

Learning Objective 1:
Learners will be able to compare energy code envelope requirements for mixed climate zone 4 and cold zones 5, 6 and 7, and calculate average R-value of wood-framed assemblies with different insulations.

Learning Objective 2:
Learners will be able to identify and overcome shortcomings in common envelope designs and avoid increasing condensation potential as assembly R-value increases.

Learning Objective 3:
Learners will be able to insulate below-ground slabs and walls of basements and crawlspaces and explain how an air barrier is created by connecting multiple envelope barriers.

Learning Objective 4:
Learners will be able to interpret data from a blower-door test to assess envelope air-tightness and utilize formulas used to estimate heat gain and loss or size HVAC capacities.
