What is the best way to make a row house in Montreal Quebec more energy efficient?
背景:位于蒙特利尔的房屋，两侧相连，建于1875年。两层楼和一间地下室。主层和二层有木地板，我不打算改变。石头的基础。地下室是70年代还是80年代的水泥浇筑?每层大约20'x40'。总面积2400平方英尺。平屋顶。相当大的后院。主楼的天花板高度是10.5'，2楼和地下室稍低一些。
Current heating/cooling: extra-old electric baseboards, and one Samsung mini-split heat pump (sounding sick and old and noisy) at the top of the stairwell, one woodburning fireplace on the main floor. There is no ductwork in the house (and no room for big ducts), but I imagine there are lots of pipes from previous hot water radiator system. Embarking on major renovations.
How would you approach the heating/cooling of this house? I should have two heating sources, I've heard.
Some options:
-Mr. Slim ductless system with a zone for each floor?
-hydronic underfloor heating for the main floor (seems feasible to install from basement ceiling)
-new electric baseboards
-geothermal system with some kind of hydronic system (underfloor/baseboards/radiators)?
-epa certified wood fireplace insert (or pellet)/or woodstove (I intend to get one of these anyway)
是否可以得到一个Mr.Slim类型的系统是好的-25和补充壁炉，如果需要?保留我的一个小隔板，并有很多的脚板加热器是不是更好?或者我应该得到一个更大的多区迷你分裂系统和补充最少的底板加热器的数量?打破地下室的混凝土地板，安装地暖和隔热，这值得吗?
Looking for heat efficiency and cost efficiency and eco-friedliness.
What would ecohome do?!
What you are describing is pretty much exactly my house in Montreal before rebuilding back in 2006. Your current heat load is probably high enough that the cost of geothermal will give you a favourable return. That’s what I did, and beyond the obvious ecological benefits of harnessing heat from the ground, it was also the right financial decision as well. The significant monthly savings in energy pays for the infrastructure, and the added benefit is that I’m paying down the system rather than watching money just disappear every month to utility bills.
Regarding radiant floor heating – I dug out the basement to create enough head room down there to increase the amount of livable space, I then laid down insulation and radiant tubing. Sounds like you already have sufficient height in the basement, but I doubt there is any insulation if it was a 70s-80s pour so I would either check it to be sure (by drilling a hole to look in an out of the way place), and if there is none you would be wise to add some. I would propose 4 inches or more if you can spare the head room.
For the rest of the house I used the existing cast iron radiators which are compatible with water to water geothermal systems, so I would recommend that route, either with new rads, or if you could check on used material sites for some old classic ones and keep that heritage look.
About the idea of installing radiant tubing between ceilings joists to warm the floor above, that wouldn’t be my first choice for a couple of reasons – it can be a real headache doing that compared to laying tubes in concrete, and as long as the home is a comfortable temperature, your feet won’t really feel cold standing on wood floors like they would on concrete.
And while I did a full energy retrofit for high end performance (It’s LEED Platinum), you could back off a bit on the insulation levels if it helped you afford a geothermal system.
As for a backup heating system, a wood stove would certainly provide you with that, but before going shopping I would recommend familiarizing yourself with the very stringent requirements Montreal has recently put in place to protect air quality. Stoves are not permitted to emit more than 2.5 grams of fine particles per hour.Here is our Wood Stove Buyers Guide Pagewhere you can learn about what to look for when shopping.
Thanks for the reply!
这房子里肯定没有隔热层。地下室已经有了一个大洞，我可以看到混凝土被浇在了原先铺在泥土上的木地板上。我要看看有没有可能把它挖出来。如果我在上面加4英寸，生活就变得复杂了。我将不得不调整原来的楼梯(我想要保留)。他们第一次倒酒就已经损失了一半。Ceiling height is about 8 ft.
I am aware of the Montreal fireplace rules, we already have a fireplace (looking into insert options) and haven't used it because of the rules.
One follow up question I have for you - in your house did you also add air conditioning? The radiators would only provide heating, right? Do you know what my options would be for cooling?
The first thing I would do in an older home is to discover where the heat and air is leaking in and out and see what reasonable measures I could take to insulate or prevent air leaks. We paid around $200 for an audit and discovered that a very large percentage of our heat was escaping through old draughty doorlocks! It was a simple cheap fix and made our kitchen and hallway warmer in winter and cooler in summer.
在那之后,I would look to fit light coloured blinds or curtains if you've any large south facing older windows - and if it's hot upstairs check on loft insulation as this is a relatively affordable upgrade with tangible benefits and ROI - I noticed ecoHOME has lots of info on insulation at //www.esb-agile.com/guides/query/insulation/
