Ten of twenty-six windows were installed today. The crew doing this work does nothing but European-style window installation. Their experience and expertise were apparent at every turn. I spent half the day installing most of the ceiling boxes for the ventilation system covering both the first and second floors with only the basement remaining to be done. Each box will connect the tubes that carry air to and from the ERV (Energy Recovery Ventilator) with the supply and exhaust diffusers that spread air into or remove air from the rooms in which they are installed. During the remainder of the day, I worked on an idea for one of my consulting gigs which is beginning to show great promise. Regrettably, I am not at liberty to disclose any of the details.
