Asked a question last year

I'm new to Passive house, and I'm working on a townhouse in Greenpoint and my client wants to use a gas cooktop, which I recognized is not preferred. The kitchen does have a window, so by NYC code exterior ventilation is required. It can have a 460 cfm recirculating hood, as per manufacturers recommendations. I'm assume I need to upgrade the ERV to accommodate this, but I'm not sure how; my mechanical engineer believes we need a dedicated ERV for the kitchen... Does anyone have experience with this?

Where am I?

In Passive House Accelerator Community you can ask and answer questions and share your experience with others!

Usually you would provide make-up air for the range hood separate from the ERV, with a damper and switch that turns the hood on every time the cooktop goes on.  But I'd start by trying to convince them to try induction.  Once you try it you never want to go back to gas.
