"We don't recommend ERV's anymore. If you are in a green grass climate ventilating dehumidifier helps solve problems without creating them. Data log before and after to understand what has been accomplished."

"Thanks Sean for your reply!      The space is pretty much open like a studio but there I am limited on how to do anything by not having an attic. So whatever I do is going to be exposed, so what would be the minimum I could run this…"

ERV Configuration

Greetings everyone,     I did an energy audit on this new home that is too tight and needs mechanical ventilation, so I thought to tell them to get an ERV installation, but then I realized that they are heating with radiant floor heating, so there is no ductwork at all and to make things more complicated, there is no attic.  To make things even more complicated, the bathrooms does not have fans, and the kitchen fan does not exhaust to outside... so I was thinking that because there is no attic,…See More

Ed Minch replied to Luis Hernandez's discussion Airsealing an old basement ceiling
"Luis Think of it as a part of the house that is not being used, but part of the house none the less.  With proper wall insulation (R-19 is my recommendation for our WZ4) and air sealing, there will not be much heating load from the basement -…"

Ed Minch replied to Luis Hernandez's discussion Airsealing an old basement ceiling
"I agree that conditioning the basement is by far the best option.  If you are going to insulate the ceiling you have to understand that the basement is now outside and you will also have to: 1) air seal the ceiling 2) insulate all walls and…"
