First, if you are building this house in NY and you are planning on electric heat as your primary heat source you are insane! Your winter electric bill will likely be 6X whatever your summer electric bill is per month. Find another way to heat your house. If you are building someplace warmer, like North Carolina you can get away with an electric heat pump and heat strips, but not up here. Also electric heat makes potential future home buyers run away screaming never to be heard from again even if they like everything else about the house.
As for trends, idono. Nothing really new and exciting IMO. However consider the following:
1. Anywhere you have a coax drop for a TV make sure you have an internet connection as well. Soon you will just stream everything off of a central media hub in your house and there will be no need for coax at the TV, but you will need an internet connection.
2. Recessed lights are nice. The new LED bulbs with included rims are expensive, but you can avoid buying trims for you lights altogether if you get these bulbs saving some money there. Cree makes a nice one that draws only 9.5W and puts out 65W of light. They can also be dimmed with no problems.
3. Under cabinet lights in the kitchen are also nice.
4. This is a good time to add a generator transfer switch. The new code requires that the neutral be transferred along with the hot conductors, so it needs to go BEFORE your circuit breaker box, which is really hard (read expensive) to do after the fact.
5. Consider at least pre-wiring for an alarm system. 20 gauge wire is cheap. Alarm systems also support inputs for leak sensors so they can be connected here.
6. Consider adding in wall speakers in your bedroom, kitchen, or in the family room with the TV. Again easier to do now, and if you don't want to buy the hardware at least run the wire so you will have it later.
