Solar can be useful, I'm told, even in Massachusetts, depending in how tight the house is. You need some amount of air movement for various good reasons, especially in places with certain kinds of rock substrate, such as granite, which provide their own problems.
With heating/ cooling, one of the things that can be useful is a heat pump, coils of tubing running through the soils around your house. The depth will vary, depending on the purpose. Frequently, however, there is a depth where the heat level doesn't vary, year round, often at about 50 or 55 degrees. If you can pump water or some other fluid through this layer, you will have a source of heat/cool at a steady temperature year round. In the summer, you can pump in through the walls and cool the house, in the winter, you can limit the amount of extra energy you have to pot into the house to bring the heat up to a comfortable level. Overall it can provide a decent savings, I'm told.
