Worst case people open windows without effect, no?

[joezydeco]

Opening windows can bring in pollen, dust, humidity, noise, and a lot of energy loss during cold winters and hot summers.

In a bedroom it might be worse than the elevated CO2 problem.

That’s a bit of a dramatic way to describe opening a window.

[joezydeco]

I've been designing my own ERV system for the house and have been weighing all the options, so I had this list in my head. Nothing dramatic, just the reality. We have allergies and like sleeping in a cooler bedroom.

[pessimizer]

As dramatic as having a runny nose and sneezing all day, having to overuse your asthma inhaler.

Is that really dramatic, or just the reality that needs to be considered in a cost-benefit analysis? Are you a hay fever truther?

[bell-cot]

Nope. Opening windows is very often disallowed - whether socially, or you'd need a hammer, or the space doesn't have windows. Or opening windows would have other downsides - letting in rain, or too-hot/too-cold air, or pollution, or ...

Can't let those stupid workers open a window and ruin the efficacy of the precisely engineered hvac system that lets the building hit LEED Platinum or whatever

[bell-cot]

Yeah. But even when you can, how many bosses might forbid it - because there's already too many arguments over the thermostats, or it's kinda noisy outside, or HR warned 'em of lawsuits for doing that when the air pollution numbers are elevated, or whatever?

[wpm]

Perhaps HR should be warning them of reduced productivity and lawsuits when the CO2 concentration is elevated.
