What are the most cost-effective green building strategies in new home construction?

我在考虑建造一个定制的房子。我做过承包、房屋建筑、被动式房屋认证等方面的研究。我绝不是一个专家,但我有一些知识,可以让我在选择建筑师和承包商时更明智。我不认为我能说服我的伴侣采取完全被动的态度,但我相信我能说服他们尽早把钱投到房子里,如果它能带来回报的话。换句话说,如果从长远来看能节省5万美元以上,我很乐意今天花5万美元。一些生态/绿色建筑策略是昂贵的,我怀疑它们永远不会收回成本,但我相信其他的是“高收益”。

Imagine a "selfish" green builder, someone who wants to build green only to save money. What eco/green strategies would you recommend to them? I know this is not a good way to think about it, but it may help me convince my partner (and maybe other down the road) to build as green as possible.

I made a list of some green construction strategies that I've read about, and I put what seem more "high-yield" at the top of the list, and the lower yield stuff at the bottom. I'd love to be corrected and educated!

  • Energy efficient HVAC system
  • “Smart” thermostat
  • Lots of wall and ceiling and foundation and attic insulation
  • Calculate the amount of glazing (not too much, not too little)
  • Having glazing facing the right direction (e.g., south)
  • Tight air-sealing of the envelope
  • “correct” type of windows (thermal conductance, transmittance, solar gain, etc.)
  • Eliminating thermal bridging
  • Efficient lighting
  • Efficient appliances
  • Solar panels
  • Geothermal heating/cooling
  • Adding thermal mass

Feel free to ignore this list completely and simply share your knowledge with me directly about the cost/benefits of different methods. I know green building is more about the attitude, philosphy, approach, than it is about specific methods; however, at the end of the day, it does involve specific materials and techniques, and these vary in cost!
