COOKING EMISSIONS & VENTILATION
-- UK study of PM emission rates for 4 full meals. "Using a cooker hood (apparent capture efficiency > 90%) and frying in non-stick pans were found to…"
thx for the update. Sounds like you made some progress.
CA still has a lot of natural draft and some (illegal) unvented gas log sets, but we are now pushing to decarbonize not only the grid but also (finally) buildings. So there may…"
thx for the reminder.
As I recall, CMHC funded some studies on this, which you probably did and know well, as would Don Fugler.
Also, Dave Grimrsud et al at U. Minn and Niren Nagda observed and recorded this problem in at least one…"
In many homes, cooking is the largest indoor source of air pollutants. Exposures can be higher in the kitchen compared to other places in the home. We can still enjoy the many benefits of cooking by installing and using range hoods that vent to the outdoors. This group will promote discussion about how to select effective range hoods, strategies to improve the efficiency of existing ventilation systems for kitchen pollutants, and what to do in homes that don’t have ducting already installed…See More
"Hi Don: good questions, as usual.
Would be great to routinely get depressurization data -- not hard to do.
See my NAPHN 2019 slides near the end for example of P measurements for installed MA system, at ROCIS Range Hood page).
good point re: PV benefit of load shifting re: waste heat.
I was referring to the whole cooling system, which is removing heat from a building. If the building shell and cooling system are not very efficient, then PV systems are…"
"re: hard data, I recall seeing at least one study that showed some cooling from PV shade on roof. Suggest you contact David Sailor's groups at AZ State U. re: their project:
Impacts of Photovoltaic panels on urban climates and…"
"Certainly did, using my eye & nose sensors.
1) smoke & lingering odors from frying bacon. Visiting family were doing that cooking (we rarely cook bacon).
Good news: the next time I cooked bacon, I put a lid over the pan, left it…"
"See list of Easy Ways to Reduce Exposure (and in some cases, toxicity) in the ROCIS Range Hood best practices guide and the NAPHN 18 slide show.
Cooking outside also helps keep the house cooler in the summer, but can add to outdoor air pollution and…"
