2020 National Electrical Code Updates Workshop

February 18, 2020, 1:00-5:00pm

Solar and Energy Storage Northeast Conference

Instructor:  Matt Piantedosi, Ridgeline Energy Analytics

Westin Boston Waterfront Hotel, Boston, MA


The 2020 National Electrical Code has been published and printed, and the adoption process is ongoing across the country. The 2020 NEC has significant changes that impact the fast-growing and rapidly evolving PV and energy storage industries: learn about the major NEC changes in order to keep your system designs, permitting, and installations on track, and to keep up with the latest advancements in system safety.

This course will review the 2020 National Electrical Code requirements for solar PV system installations. It provides visual examples of the various equipment as outlined in Article 690.2. Key code changes will be provided for sections pertaining to PV installations, including Articles 690 and 705, as well as services in Article 230, grounding and bonding in Article 250, and wiring methods in chapter 3. During the course, there will also be an in-depth analysis of Article 690.47 Grounding Electrode System Requirements, Solar Labeling Requirements, Rapid Shutdown and Article 705 Interconnection Requirements and Calculations. Photos of installations throughout the Northeast will be discussed to illustrate key topics.

Attendees earn 4 North American Board of Certified Energy Practitioners (NABCEP) Continuing Education Credits upon completion of this workshop.

Is Your Building Healthy? When it’s Time for a Retrofit

Metrus Blog by Maggie Molina, Senior Director for Policy, ACEEE,  February 26, 2019 

“Don’t put off for tomorrow what you can do today,” said Revolutionary sage, Ben Franklin. But when it comes to building retrofits, knowing how and when to invest in energy efficiency can be daunting. We called upon David Korn, founder of Ridgeline Energy Analytics, and his 20 years of experience identifying buildings in need of retrofits, to provide insight into the key things to look for when considering a retrofit. This simple three-step review can help you determine the overall health of your building— and if it’s time for a retrofit.  More


Uncertainty Assessment for International Performance Measurement and Verification Protocol (IPMVP)

Efficiency Valuation Organization releases a new IPMVP Application Guide, April 16, 2018

The Efficiency Valuation Organization (EVO) is pleased to announce the release of a new application guide Uncertainty Assessment for IPMVP (EVO 10100: 1:2018). This document is a revised and expanded version of the Statistics and Uncertainty for IPMVP (EVO 10100 1:2014) application guide published in 2014. The new application guide includes examples for each of the four IPMVP options.

M&V efforts are designed to determine energy and demand savings with some reasonable accuracy. However, this objective can be affected by either systematic error (i.e., not occurring by chance, including measurement error) or random error (i.e., occurring by chance and often due to using a sample rather than a census to develop the measured value).
