Building Science & Ventilation

Building science includes a focus on indoor comfort, air quality and safety, all of which most HVAC contractors are familiar with. Proper ventilation is a key component of controlling each of these home issues.

Building science also encompasses home durability and performance which are topics that are new to this industry and not well understood by many HVAC contractors.

  • Interactions between structural, mechanical and service systems are examined to illustrate how heating and cooling systems can be impacted.
  • Examples of construction quality showcase the importance of attention to detail during the construction process and the impact on HVAC systems and energy efficiency.
  • Home diagnostics using pressure measurement tools is illustrated as an additional diagnostic resource for heating and cooling equipment.
  • Participants will see how home diagnostics is improved when new technologies like infrared thermal imaging are used.
  • The physics of pressure, heat and moisture movement throughout a home are explored, as are their affect on average and high efficiency homes.
  • New ventilation options, approaches and designs are explored. The relationship between ventilation design and the structural efficiency of home is also illustrated.
  • Improved diagnostic processes for HVAC systems and indoor air quality are presented to illustrate the importance of protecting home durability against moisture damage.
  • A detailed look at indoor air quality problems is presented. The impact of VOCs, radon and other contaminants on the health and safety of occupants is also examined.
  • An overview of ASHRAE 62.2 3013 is presented to illustrate current ventilation code requirements for residential structures.
