Guide to Near Net Zero Residential Buildings (NAIMA Canada)
The Guide to Near Net Zero Residential Buildings is published by NAIMA Canada. This guide consolidates information on how builders and designers may achieve the near net zero energy efficiency targets in current and upcoming codes, including the British Columbia Energy Step Code. This guide is intended to be an industry resource for designing and constructing low energy use buildings using mineral fibre insulation without compromising other aspects of building performance including moisture management, airtightness, and durability. This guide is limited to Part 9, wood-frame construction, with a focus on British Columbia, though the principles in this guide may be applied throughout Canada.

Inside the Hidden World of Elevator Phone Phreaking | WIRED
"THE FIRST TIME I called into an elevator, I picked up my iPhone and dialed the number—labeled on my list as the Crown Plaza Hotel in Chicago—and immediately heard two beeps, then a recording of a woman's voice, who told me to press one to talk. When I did, I was suddenly in aural space filled with the hum of motors and the muffled twanging of steel cables under tension. "Hello, can anyone hear me?" I asked the void. The void did not respond.

I hung up and tried another number on my list: A Hilton hotel in Grand Rapids, Michigan. After just one ring I heard a series of four tones and was immediately listening to the inside of another elevator. I heard a chime, perhaps a signal that it had reached a floor, followed by the rumble of what might have been a door opening. "Hi, is anyone in here?" I asked. This time I heard a few muffled voices, then a woman answered: "There are people in here, yes."

Sounding a little more excited than I intended, I asked if anyone was in an emergency situation, a strange question I felt compelled to lead with, to make sure I wasn't tying up the elevator's phone line when the occupants might need it. I got no answer except what sounded like the rumble of the door opening and closing again.

So I stayed on the line. A few seconds later, the elevator chimed, and I heard the noises of new people entering. I greeted them as I had the first passengers, but they didn't seem to hear me even after several attempts. "Turn it over," I heard a woman's voice say in a Midwestern accent. "The lady at the desk just said to hold it," a man said. I realized I was listening to a couple trying to figure out how to use their keycard to unlock the button for their floor of the hotel. I felt a transgressive excitement, a sense that I was eavesdropping on a conversation I shouldn't be hearing, and I instinctively hung up the phone.

This was my introduction to the illicit thrill of elevator phone phreaking. (..)

Since then, Caruana has learned the tricks to identify those secret elevator phone numbers, some of which have been used by phreakers for at least 20 years: Call sequential numbers left out of a building's directory to guess the ones that might be elevators. Open an elevator phone cabinet, attach alligator clips to the phone line, connect your own phone, and call 1-800-444-4444, which reads your number back to you. Or simply ride in the elevator, hit the button, and impersonate an elevator technician who needs to know the line's number."
