Course Outline

Welcome - Orientation Materials

This course is self-paced, so you don’t need to be logged in at any specific time. You can complete the material whenever is convenient and work ahead or catch up if you fall behind. The course discussion board is a great place to interact with other students and ask questions. Expect to dedicate a minimum of 5 hours per week to the course. Course materials will remain in your account with minimum guaranteed access for 12 months (1 year) after enrollment. Typically access is extended for much longer. Your instructor will be in the course and participating in the discussion during the posted session dates. Please review the orientation materials and introduce yourself on the discussion board.

Week 1 - Applications of Solar & Radiant

The course begins with a discussion of solar (heating & PV) and radiant technologies, how they are complementary, advantages, and challenges of integrating them.

Week 2 - System Types and Stagnation

This week we'll discuss the types of solar heating systems commonly used for solar combisystems and explore the overheating considerations that are unique to solar combisystems.

Week 3 - Techniques for Integrating Solar with Radiant

Beginning this week, we'll get into the details of solar storage strategies, and control considerations in solar combisystems. You'll learn some techniques to assist with system design for your project. This week spills into Week 4, where we will explore codes and standards related to these systems.

Week 4 - Code and Standards Considerations

This week we'll discuss codes and standards related to solar heating, including the USEHC, ASME requirements, ComibSol Best Practices, and other key design and installation requirements.

Week 5 - Combisystem Economics

In the sales process, prospective clients will often inquire about the benefits of a solar heating system. Analyzing system production when integrating solar with a radiant system requires understanding of building science and solar modeling programs. This week, we will analyze the information needed to model these systems and examine how to use the results of these models to support the sales process.

Week 6 - Capstone Project

To finish out the course, you're going to design a full system, including drawings, calculations, and equipment selection. You'll walkaway with the confidence to do these designs on your client projects.

After The Course - Feedback and Additional Resources

No matter how great this course is, we know it's just one part of a bigger journey. In this module we'll start thinking about what comes next.
