High Relative Humidity in New Construction House
I live in Seattle (currently 60 degrees, 87%RH) and have just moved into my new construction house - RH 70%. Through the construction process, I have introduced a lot of moisture into the home - damp cellulose insulation, suspended concrete slabs main and second floor, full basement (properly waterproofed with exterior/interior drainage/sump with upslope curtain drain and tightlined downspouts), textured drywall and paint.
Reading this site, I read M Holidays article which suggested I may be adding more moisture into the house by my use of a HRV- since the RH outside is higher than inside.
My current strategy to lower the RH is to keep spot fans running in all bathrooms, run a dehumidifier in the basement, run the HRV on low...and limit the kids and dog to ... marginal mayhem.
What other strategies are recommended? Also, are there quality dehumidifiers where I can tackle high RH while minimizing an energy penalty?
