I am looking for a local firm in Southeastern MA. to perform a Manual J or equivalent for a passive solar new construction in zone 5A. I read manual J is not recommended for passive solar in their instructions. I plan on using mini-splits and an erv for ventilation. Most locals are not qualified and I don’t want to oversize system. Thanks

Joseph,
Sorry, but I don't have a recommendation. While you're waiting for someone to chime in, you might want to check out Martin's article on reassessing passive design: https://www.greenbuildingadvisor.com/article/gba-prime-sneak-peek-reassessing-passive-solar-design-principles

thank you Jon A
