Energy Revolution in a Brooklyn Townhome
Tim McDonald here from your class. Looks like things are going well for you on the Park Slope townhouse. Congrats. It’s really inspiring to follow your progress. Wondering where you get your ComfoAir HRV and how much it cost. Also why not the UltimateAire? Also have you any experience with Shuco Solar panels? Wondering if you went with Heliodyne for a reason. I’m told Shuco is a great product but I’d love your thoughts. Just started a 27 unit town house project in Philly and it’s gonna be our first Passive House development as well as our first modular Passsive House project! Not too much to bite off aye? Anyway, appreciate any feedback.
Hi – I was wondering if you had considered a plumbing wastewater heat exchanger as a supplement to the solar, to help recover heat from showers, etc?
Thanks for the question. Yes we did consider the waste water recovery system GFXTMHeat-Xchanger, but due to other change orders and cost issues we decided not to implement that on this project. Since we are already preheating the water with the solar we would have a slower payback with the heat recovery than if we didn’t have any preheating system in place. On my projects were we are not doing solar thermal I think it is something that we will implement in the future; where cost is not a concern we will install in with a solar thermal system for the dual benefit because it is a good idea.
