我想请教我是否应该用Energy Star 取代EnergyWise.

还有,Two stage high efficiency two pipe furnace c/w ECM motor 是什么意思?

不好意思,因为是第一次买房子,所以很多问题不懂:p,先谢谢各位了.
 
I guess you are looking at minto houses. EnergyWise is their old upgraded insulation standard since 70s. Energystar is their new one since 97.
At 2006 new ontario building code, most of thing minto included in their energystar already are included. They have to build house to meet the code. So buy energy star package makes no sense.

Two stage high efficiency two pipe furnace c/w ECM motor
basicly is the furance can vary its heat output and vary this blowing motor speed. If you are the personal like to have even temperature at everyroom and at all time by keep blowing fan running 24 hours. Or use a HRV system to keep air fresh. It will save you some eletricity. But at higer cost of furance.
for most people a single stage, single speed ac motor fuance is good enough.

Both upgrade wouldn't increase your house value when you sell your house. Some minto home has optional room or double garage upgrade, spend your money on that is better.
 
Two stage: furnace has two settings. the low setting will start 1st. after 10min, if the temperature has not reached pre-set value, the high will kick in.
two pipe high efficiency: furnace has a separate vent (2.5in plastic) pipe going through basement wall
ECM motor: blower powered by DV, instead of AC. saves 60% elec.
all these make it high efficiency 90-92%

You can get rebates from Fed and On. if you replace old one with high efficiency. But the new construction does not qualify.

借贴问一下版主

把地下室高度增加12",4882.50,值吗?有必要吗?
是walkout basement。
另外,新房有必要让builder把楼梯升级成实木的吗?是不是不升级以后就不容易了?
谢谢!
 
谢谢版主和mmb的回复。

另外还有一个问题,听建筑公司的设计人员说,如果把地下室的窗户加大效果和增高地下室差不多,但是费用会减少,是这样吗?
 
a regular room the ceiling high is a least 8 feet, 9 feet is better. If you like to use basement as regualr living space, after seal the ceiling it should at least has 8 feet high.

So do it or not do it, it depends how high it already is.

Walkout basement worth something will you sell your house. add money to it make sense.
Regualr basement don't. so don't put money to it.

on the other hand if the house is small and the basement is used as family room, I would add more high to it. It just makes living more comfortable.

No. It could be done later easily.
 
可是有朋友说,如果现在不升级成实木楼梯,以后就只能贴面了。效果差很多。
 
You would not be able to save money if you want to do it later on as you need to remove the whole railing/spindles, and re-cap, stain finishing, and then re-install the railing/spindles. There is lots of work. The stair company will charge you almost the same as install the new stairs. You may have some detail finishing mis-match, like nosing-ceramic height mis-match, etc.
 
谢谢novadalhomes!
如果只让builder升级实木楼梯,房子建好后自己找人铺实木地板好不好?会不会不match? Builder铺地板太贵了。
 
That is a good way to save money. It is better to make sure that the color of the stairs is right...I means match the color of the hardwood in the future.

谢谢novadalhomes!
