Indoor Air Quality or IAQ refers to the quality of the air we are breathing when we are indoors.   This module will teach you about indoor air quality, the things that lead to poor indoor air quality and what we can do to improve our IAQ. You will also learn about the standards that provide the requirements for mechanical ventilation sizing and air flow testing.

Every building sits on a foundation of some type. Learn the minimum rated features and data you need to gather that relate specifically to each type of floor or foundation. You will also understand the minimum rated features around area and volume calculations that create the basis of the rated unit calculations.

Envelope wall energy performance varies based on construction, materials, insulation, location, even exterior color.  This module covers the minimum rated feature of Walls Assembly and the data that must be collected about the structure's envelope walls.

There are several types of ceiling assemblies and the impact to energy usage varies with the specific construction details of each type.  The ceiling's relationship to the roof is also important and there is quite a bit of information that must be gathered about both ceilings and roofs.  This module explores those data points.

This module explores rim and band joist evaluation protocols, including what to do when the rim or band area cannot be inspected by the HERS Rater or RFI.

Fenestrations are the holes we make in our walls and ceilings for windows, doors and skylights.  This module covers the evaluation and data collection protocols for each of these.

Passive Solar Sun Rooms provide energy savings to a structure by reducing heating, cooling, and lighting energy needs.  This module explains the data collection and modeling protocols for such a structure.

One of the tests performed during a Home Energy Rating is a test to determine the airtightness of the building or unit envelope.  This module explains how this test is performed and the resulting data you can expect to receive from it.

A duct leakage test is performed during a Home Energy Rating to determine air leakage from the heating and cooling distribution system or ductwork.  Even if there are no ducts, there is still data gathering that must be completed. This module explains the data gathering involved and the protocols involved to model information from this test.

This module covers the minimum rated features around heating and cooling equipment, water heating equipment, and mechanical ventilation equipment.  It includes what the inspection protocols are and what information is required to be gathered regarding this equipment.

Appliances can use a lot of energy!  This module defines the data that must be gathered for the refrigerators, freezers, dishwasher, stove, oven, clothes washer, and clothes dryer.

Lights can save energy or waste energy, they can add to the cooling load or reduce the heating load.  Ceiling fans may help reduce energy usage or increase it based on where in the country the home is located.  This module covers the data elements that must be gathered for lights and ceiling fans.

Solar systems have become increasingly common.  This module will take you through the various types of solar systems and the data that must be gathered for them.

This module will mentor you through generating a full energy model for our first project. We will work step-by-step through an entire modeling session from plan review and equipment efficiency research through actual modeling in the rating software tool.

This module will mentor you through your second project and verify your energy modeling work.

This module will mentor you through generating a full energy model for our third project.
