John F. Robbins CEM/CSDP
Energy Consultant in Morning View, KY
Mr. Robbins has been a residential and small commercial designer and energy consultant since the mid-1980s, having worked on projects in 13 states but mostly in Ohio, Indiana and Kentucky. His projects aim for much lower utility bills and energy usage with less negative environmental impacts. Mr. Robbins also designs and consults on super-insulated passive solar homes which sometime include solar water heating and solar electricity. He consults on stand-alone renewable energy projects like the battery-backed PV electric system which has powered his office since November 2001.
Mr. Robbins serves on the board of the Southwestern Ohio Chapter of the Association of Energy Engineers (AEE). He has earned two AEE certifications, a “CEM” for energy management and a “CSDP” for sustainable development. Mr. Robbins has received six awards from AEE since 1990 for energy and environmental achievements, including 1994 Southwestern Ohio Energy Engineer of the Year and 2004 Southwestern 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 led the Southwestern Ohio Alternate Energy Association (AEA) from 1995 to 2005, Mr. Robbins is also well known for encouraging, assisting and teaching energy users to become more aggressive and hands-on in managing and minimizing their heating, cooling and non-HVAC energy use. Whether designing, consulting or educating, he teaches that reducing conventional energy use is equal to new renewable energy supplies. Since 2005 his educational offerings for professionals as well as energy users have been hosted or sponsored by Great Oaks Institute in Southwestern 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. Since 2016 Mr. Robbins has held the “Speaker Chair” for Southwestern Ohio AEE. As speaker for the chapter, he develops and provides energy presentations to local high schools and colleges when requested.
Mr. Robbins sells no products, receives no commissions for referrals and has had no commercial affiliation with manufacturers and retailers of products and services which he has used, recommended or specified.

Course Title: Designing More Thermally Efficient Residential Envelopes for Northern Cold and Mixed Climates
Delivery Method: Live Online
Course Description: This course will evaluate several factors to consider when designing thermally efficient residential envelopes in cold climates. Topics include what a cold climate is and which energy code climate zones are predominantly cold, and energy code envelope requirements for mixed climate zone 4 and cold zones 5, 6 and 7.
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.
Learning Objective 2:
Learners will be able to review the R-value and airtightness of different insulations.
Learning Objective 3:
Learners will be able to explain how to avoid increasing condensation potential as assembly R-value increases.
Learning Objective 4:
Learners will be able to discuss and reference formulas used to estimate heat gain and loss or size HVAC capacities.
LUs: 2.0 LU Type: LU|HSWs.
Prerequisites: Some experience with residential design
Advance Preparation: None
Program Level: Intermediate
Course Expiration Date: 03/04/2025
