New for 2023!  We have added 8 discussion forums at the end of each session to give participants an opportunity to explore topics in more detail with knowledgeable professionals.  Whether you register for one topic or all four, you will have the ability to participate in ALL of the discussion forums.  

Forum topics include:  The pending changes to Maine’s building code; a primer on ASHRAE 62.2-2016; sizing heat pumps; sizing ventilation systems and ERVs/HRVs; installing ventilation systems; radon mitigation; mold testing and understanding the lab report; basement renovations; mold remediation; and high performance tapes, wraps, and building products.


Get ready for 2023! After a three year break from in-person trainings, the Maine Indoor Air Quality Council is again is presenting its popular residential construction training series, where you’ll learn how to optimize energy efficiency measures as well as minimize the risk of moisture and indoor air quality problems in new and existing homes.  The trainings further emphasize this critical concept: high performance homes are not hard to construct, and the extra efficiency measures have a very reasonable payback – both for the builder and the homeowner.

The workshops include illustrations of current Building and Energy Codes (IECC 2015, IRC 2015, ASHRAE 62.2 2016, and ASTM E-1465-2008); Energy Star Guidelines; Zero Energy Ready Guidelines; and Passiv-Haus Guidelines. They further provide an introduction to basic building science and IAQ principles, and incorporate humor to convey the core concepts. The program trainers William A. Turner and David Johnston, provide a perfect blend of building science technique with practical, pound-the-nails guidance.

At each session, you’ll learn:

  • Proven cost-effective and energy efficient building construction techniques
  • The physical processes that require attention:  how air, moisture, and heat move in and out of a home
  • Practical strategies to effectively and economically address both energy efficiency and indoor air quality
  • Case studies from actual projects (participants are encouraged to bring issues to the sessions)
  • Specific references and resources, such as Codes and Standards; DOE’s Building America Solutions Center,  EPA’s Energy Star with IAQ Plus Sites, Passive Haus; Net-Zero Ready Homes; Aging in Place; and private publications

About Foundations:  Proper site work and foundation construction are as critical to the overall quality and healthfulness of a home as the building shell that is constructed above grade. As a result, a builder’s job begins before the very first shovel of dirt comes out of the ground, not after the foundation is completed. This program highlights the physical processes at work below grade (temperature, water, moisture, and air) and how they can cause a variety of problems that not only may affect occupant health, but may also drastically compromise energy efficiency and the building structure. The session offers practical how-to guidance on ways to avoid mistakes in site drainage and foundation construction: mistakes that are costly and difficult to fix after the home is completed.

New for 2023:  Interactive building science demonstrations, including introduction of techniques to calculate dew point on building surfaces.

Learning objectives for Foundations:

  1. The how’s and why’s of foundation drainage, bulk water management, and vapor management
  2. The difference between “damp proofing” and “water proofing”
  3. The how’s and why’s of thermal breaks between earth and structure below ground
  4. How to create true capillary breaks between earth and concrete, concrete and wood
  5. The radon problem and how to minimize it
  6. Strategies for successful insulation of the critical floor slab/footing/wall joint
  7. Benefits of insulating basement walls and floors versus insulating basement ceiling
  8. The ASTM Radon Resistant Construction Standard
  9. Basic interpretation of infrared imagery
  10. How a “finished basement” will influence new construction decisions
  11. How to calculate dew point on building surfaces


The Building Shell

Friday, February 3, 2023

About the Program:  Simply put, a new home’s building shell is comprised of the structural elements that separate the inside from the outside: walls, roof, windows, doors, including things that govern long-term performance: air barrier, wind barrier, vapor diffusion layer, insulation, drainage plane, and exterior cladding. The shell’s function is anything but simple. It has to protect its occupants from rain, wind and snow. It has to control the flow of energy and heat between indoors and outdoors. It has to control the flow of air and moisture. It has to provide light and a means to enter and exit, and allow pollutants and contaminants to flow out of the building. The shell has to create an environment that is comfortable indoors, when conditions outdoors are not. And, it significantly determines the affordability and energy consumption of a home. This program presents practical techniques building professionals can use to achieve all of these goals and still provide healthy IAQ.

Learning objectives for the Building Shell:

  1. How to define air tightness in a building enclosure
  2. How to manage both bulk water and water vapor
  3. Air flow management in a building enclosure
  4. The importance of a well-sealed air barrier
  5. The varying impact of moisture on common building materials
  6. Minimizing heat bypasses to minimize condensation and heat loss
  7. Various approaches to design a wall system with an R value greater than R=30
  8. Various approaches to design an cathedral ceiling with an R value greater than R=40
  9. Basic interpretation of infrared imagery of wall systems
  10. Critical components of good roof design in heavy snow areas in cold climates


Friday, February 10, 2023

About the Program:  Building and renovating homes in Maine’s climate is a challenge. While most customers demand that their homes be constructed and renovated to minimize heat loss – most customers don’t make similar demands for adequate ventilation and moisture management. Yet ventilation of a Maine home, particularly an energy efficient home, is one of the most critical construction issues Maine builders need to address in order to prevent call backs and problems down the road. Properly ventilated homes minimize the risk of exposure to indoor environmental pollutants (radon, carbon monoxide, carbon dioxide, combustion pollutants, chemicals) and minimize the risk of moisture damage in the building envelope and subsequent biological contamination. This program stresses why controlling ventilation in a home is necessary to protect occupant health. It will discuss the most common sources of indoor air pollution in homes and how they get there, and what physical processes are present (air flow, pressure, moisture) that affect indoor air quality. The program provides practical strategies to achieve energy efficient heating, moisture control, and core ventilation goals.

Learning objectives for HVAC:

  1. Do you or don’t you “build tight, ventilate right”?
  2. The three primary driving forces of air movement in or out of a building
  3. The basic rules of moisture movement
  4. The consequences of insufficient “make-up” air
  5. How and why to apply ASHRAE 62.2
  6. Atmospherically vented combustion appliances vs. sealed combustion
  7. Describe various approaches for ventilating a home
  8. Describe various approaches for effectively ventilating cooking areas
  9. Describe various approaches to HVAC and domestic hot water with combustion devices and/or heat pumps
  10. Key components of good year-round ventilation, heating, cooling, and humidity control


Friday, February 17, 2023

About the Program:  This session focuses on practical short and long-term strategies to both maximize current and future energy efficiency and minimize IAQ problems when undertaking common residential renovations.  The program covers identification of potential IAQ hazards in an existing home, understanding how specific renovation projects can impact indoor air quality, and strategies to both renovate a home for improved energy efficiency and AND reduce health risks for home occupants.  Covers: weatherization, basement improvements, roofs, windows/doors, bathrooms, kitchens, additions, and ventilation.  Case studies of actual projects will be used to illustrate training concepts.

Learning objectives for Renovations:

  1. Why pre-evaluation of the structure for chronic moisture, water stains, wood decay, lead paint, asbestos, and radon is so important
  2. The implications of excess moisture on the underside of roof sheathing
  3. Planned management of air flow, humidity and combustion safety
  4. Safe lead paint and asbestos removal practices, and effective radon management
  5. Various means of providing make up air for an existing atmospherically vented combustion appliance
  6. The causes of ice dams and how to eliminate them
  7. Why an oil-like smell, cracks, and high water marks may be a concern in an existing basement
  8. Describe various approaches for deep energy retrofits and building resilience
  9. Determining when and why various types of energy retrofits make sense
  10. Considerations for special buildings (e.g. log homes, historic structures, and aging in place)
