By Noah Lawrence, Technical Trainer & Customer Success Lead, Retrotec

When I first entered the energy efficiency industry, I was a freshly certified, overly optimistic college grad who thought, "How hard could this home performance thing be?" So naturally, I started my own company.

I had just completed an online course with a one-day in-person training, passed the exam, and purchased a shiny new set of energy auditing equipment—including a Retrotec 5100 blower door with a DM32 gauge. My first paid blower door test was booked, and I was excited. I lucked out: my cousin had just built a house with an apartment above the garage in a town that had only recently started enforcing New York State’s energy code blower door testing requirement.

I offered him a great deal—on two tests—and severely underpriced the value of what I was providing. That was lesson number one: Set

Introduction

The Genesis of the Project

In a full-circle moment, Retrotec recently joined forces with Jon Walters from Northwest Design (NW Design) to conduct a critical blower door test on his newly constructed multi-use building. Since 1995, NW Design has been a loyal partner and supplier to Retrotec, delivering top-notch fabric products such as Cloth Door Panels, Carrying Cases for our aluminum door frames, and carrying cases for our blower door fans and digital gauges. It was high time we returned the favor.

A Building Journey Rife with Challenges

Initiated in 2020, Jon and his father embarked on a mission to erect a 21,000 sq ft. multi-use building adjacent to NW Design's existing facility.
