Course description

When you're designing a zero net energy home or a battery-based solar PV system, electrical loads are the biggest headache. They're very hard to predict!

This presentation covers the subject of plug load energy-efficiency -- the choices occupants make with regard to lighting, appliances, and consumer electronics in the home. You will glean priceless information about how to save hundreds of dollars towards lowering your (or your clients’) utility bills.

The presenter is Chris Calwell, one of the best in the business.

Ecos Research

I focus on transformative changes to how and why we use energy. The constraints climate places on our fossil fuel use are fundamental and absolute, so I seek opportunities to utterly break our reliance on them through zero net energy buildings, renewable energy sources, efficient plug loads, and electric transportation options. In practice, this means finding... Learn more

I enjoyed the course ,it has been eye opening.I have learnt a lot

by Donovan Richie 09/24/2023

This course was eye-opening for me as I begin my journey into learning about green buildings. Prior to taking this course, my thinking about home energy efficiency was limited to things like site selection, building orientation, daylighting, building envelopes, thermal insulation, and HVAC equipment. After taking this course, I understand better how the appliances and consumer electronics we choose to put into our homes have a big impact on how energy efficient our homes actually are. This course also introduced me to online tools like and that I can use to identify more energy efficient products for my home. And Chris Calwell is an excellent presenter to learn from! He is a super smart guy who can make complex ideas and information easy to understand.
