The Case for Small, Local Engineering Firms

Posted by Jennifer Chiodo on Jul 26, 2018 4:29:30 PM

My business partner, Matt Napolitan, and I each spent 10 years working at major, international engineering firms. I worked for Syska Hennessy Group (11th nationally ranked) in their San Francisco office and Matt worked for Buro Happold (14th nationally ranked) out of their New York office. We now operate a 12-person engineering consulting firm in Burlington, Vermont. We know both large, big-city engineering and local, Vermont engineering.

Project Management Basics – Five Rules for Successful Additional Service Requests

Posted by Jennifer Chiodo on Jul 19, 2018 3:31:59 PM

The first project that I managed as a young engineer was a tenant fit-up for a high-rise building in San Francisco.  Through a variety of random events, as a 22-year-old electrical engineer, I became the project manager as well as the project engineer for over 30 floors of mechanical, electrical and plumbing design for an oil company building out of its new west-coast headquarters.  Early on, I recognized that our fees were based on a limited scope of work and, as the client changed what they wanted in the space, I needed to make a case for the additional effort necessary to provide the services needed for the fit-up.  In some cases, it’s obvious when a project exceeds the contracted scope of work; for instance, the client added a large data center that required a code variance (another blog topic perhaps).

Using Market Smarts to Enhance Energy Efficiency Program Evaluation

Posted by Jennifer Chiodo on May 30, 2018 2:30:00 PM

Generating Market Demand

The purpose of energy efficiency programs is to cost effectively generate market demand for energy efficiency that would not be achieved without market intervention. An energy efficiency process evaluation investigates the effectiveness of programmatic interventions through qualitative and quantitative analysis. Marrying the analytical engineering-based approach of impact evaluation with the typically more social science orientation of traditional process evaluation can generate useful, actionable results to help program administrators improve market interventions to increase participation, depth of savings, and market transformation.

Earth Week - It's Not Enough

Posted by Jennifer Chiodo on Apr 25, 2018 10:00:00 AM

First, let me acknowledge that my own life is harming the planet on which we live. I drive a car, I buy stuff packaged in plastic, I have pets – all things that I know to have a negative impact on the planet that sustains me, my family, my friends, and everyone else.

Who is Responsible for Low Energy Code Requirements for Lighting?

Posted by Jennifer Chiodo on Mar 14, 2018 2:00:00 PM

I have repeatedly blogged about my concerns with the current and future energy codes because the codes are not keeping up with technology for lighting efficiency (see my previous blog posts titled “Why are Lighting Energy Standards Decreasing” and “More Issues with the Energy Code – Lighting is Running Rampant”).  The graphs below, developed by our friends at Optimal Energy, show some comparisons of Department of Energy (DOE) predicted efficacies for lighting technologies and the efficacy needed to meet code for some common space types.

Building Retrofits: The Retrocommissioning Approach

Posted by Jennifer Chiodo on Feb 21, 2018 1:28:36 PM

If you're the owner or manager of an older commercial building, you may wonder if retrocommissioning is right for your building retrofit. You are not alone.

Designing Buildings for Resiliency To Accommodate Power Failures

Posted by Jennifer Chiodo on Nov 1, 2017 10:00:00 AM

I’m writing this blog from the floor of the Andover Public Library in Andover, MA. After a major windstorm, power is out all over New England and people are scurrying for the few available power outlets and sources of internet.

Dangers of TMY3 Data in an Era of Changing Climates (Part 2)

Posted by Jennifer Chiodo on Mar 8, 2017 12:00:00 PM

Hi, it’s me again – two blog posts in a row!  I still haven’t had the time to compile the full TMY3 comparison picture that I envisioned when I started this rant. (See my last post if you want to learn the TMY3 basics.)

Is Typical Meteorological Data Relevant for Energy Analysis? (Part 1)

Posted by Jennifer Chiodo on Mar 1, 2017 10:00:00 AM

When we undertake energy analysis for commercial building energy retrofits, retro-commissioning, and even new construction projects, we normalize the energy savings to try to reflect average savings over the life of the measures.  For measures like HVAC upgrades, savings are usually weather-dependent.  The industry has used Typical Meteorological Year (TMY) data as the basis for weather normalization.  These TMY data are generated by the National Renewable Energy Labs (NREL) and include actual weather data that is determined by NREL to be representative of typical weather over time for each month.
