Air-to-water heat pumps have generated a lot of excitement for their enormous retrofit potential. This case study details one home’s retrofit to an AWHP system, which was developed by hydronics experts to be simple and repeatable.
This course will provide an overview of the mechanics of this alternative heating system, as well as discuss the advantages and disadvantages of installation, capabilities, and control.
This course will provide an overview of Solar Thermal mechanics and capacity. It will also discuss the advantages and disadvantages of installation and control.
This second course, designed for Footprint Project volunteers, describes more of the details of a solar generator, what it can power, and basic safety.
This short, free course covers the role of distribution automation in electric utility grid modernization efforts.
This course will explore in depth how to model solar projects on Time-of-use (TOU) rates, and how they effect the 'value of solar' calculation.
Factory Training For the I-TEC indoor wall-mount A/C & Heat Pump
This free course includes a discussion on optimal environmental conditions for flying, what hardware and filters to consider, what camera settings are best for various circumstances, and several examples from projects around the world.
This course explains why you need Residential Energy Dynamics' Zone Pressure Diagnostics (ZPD) tool, how to use it, and much more.
This free course employs case studies to illustrate the integrative design process—with its focus on purpose, discovery, and interrelationships.
What are the best online software tools for solar designers? This free solar design course was created by Unirac to help solar designers work more quickly and confidently.
Should we be trying to electrify everything? Is it practical for existing and new buildings with the technologies we have now? Two engineers with different takes on these questions will debate electrifying residential buildings.
This free course is a recording of two webinars by Robert Bean on understanding and integrating ASHRAE standards on thermal comfort, energy efficiency and indoor air quality for HVAC and building design.
This lecture covers just how heat and moisture can move in building assemblies, how to manage both, and the tools that are available to evaluate or predict hygrothermal performance of building assemblies.
In this lecture, hydronics expert John Siegenthaler explains the importance of low water temperature heat emitters and distribution designs in modern hydronic systems.
Solar companies are scrambling to comply with new prevailing wage and apprenticeship labor requirements. The laws and rules are confusing, even for smart people. We break it down into simple, actionable steps that a normal person can understand.
We hired a "Researcher-in-Residence" and gave him access to all of our student performance data, including detailed video metrics. What he found is laid out in this free course.
Examine cellulose vs. fiberglass insulation, interior vapor control membranes, diffusion vents at the ridge, interior humidification, inward vapor drive issues, and the effect of air barrier imperfections.
Este curso de seguimiento de certificación repasa los conceptos básicos de la energía solar y cómo instalar un sistema de techo inclinado.
Important findings from a rigorous, months-long analysis where we studied the economics of solar + storage projects on every C&I (commercial and industrial) utility rate tariff in California’s Investor-Owned Utility (PG&E, SCE, SDG&E) territories.
