Keep you space conditioning systems in the insulated building envolpe- too much sweating, condensing, air leakage, and poor efficiency. If you suceed at air tightening, you will not need a winter humidifier. Avoid ERV/HRV because of poor payback. Suggest 50-75 cfm of fresh make-up air ventilation, I prefer a ventilating whole house dehumidifier for fresh make-air ventilation, air filtering, and summer dehumidification instead of over-cooling the home during the wet cool weather which causes a damp basement. This must be confusing!

Thanks for all the replies so far - please keep them coming.
Any suggestions on insulation methods and ensuring the right "tightness"?
How about one of those ERVs - do we need one if the system is forced air to begin with?
Is the basement considered within the thermal envelope? I think that's where the main equipment and ducting will be.
And yes, New Jersey summers are very hot and humid (though sadly not very long).
