I was in middle of planing the renovation of my Bungalow to as much "Pasive Home" as I can get it to be, when I was told by my new neighbor to my South (8ft away) that he is going to build a two story home which will "cover" my winter mid- morning to early afternoon sun. I can use any advice I can get how to proceed with my progjct. Thank you

Sell your home and move. You cant have a passive solar home without south window exposure. Other than selling and moving you can stay put and just not rennovate.

"Passive House" standards do not require solar gain, although it is helpful. while "passive solar" houses do require it. But, I'd consider moving if I was going to be living in a perpetual shadow.

You can still super-insulate your home and reap the benefits and comfort. Or start making lots of noise late at night - maybe he will move...

Thank you to all.
Moving is not a choice I will make but thank you anyway. I live in the middle of Toronto with a swiming pool, 11,000 galon Kio pond and I have just finishe building a 36 ft greenhouse. I will take NFC advice and super insulate my home . At least I will pay less to the gas company and Hydro and enjoy being here. The shade will be only over my home but not over my back yard. Therefor I am still O.K. in my green house and so are my Water Lilies and my Lotus.If I was to not invest in Supper Fiberglass windows what will be the next best chice for me ?.

Super insulating is one thing, but more important super seal it!

You may have to get an energy audit to evaluate all of the options - there are many.

Since you are in Toronto, you could get a really good German fibreglas REHAU window at a better cost than the local Fibreglas.

I have some other "passivhaus" sources if you want to contact me.

I agree with jonr, whirnot and BobI. Superinsulation isn't going to be very effective if your house is leaky. A good energy audit will tell you where you will get the most bang for your upgrade dollars for your specific house.

If you can't find a good energy auditor, then software such as BEOpt should be considered.

I would recommend an audit. You need data to find out where you are currently at, then do the work and then get a post test to make sure goals were met.

Anything less is poking in the dark.

I found a very informative European site on Passive House design. It is in English, so no German translations needed:

Euro Passive House Window Info

Euro Passive House Directory

Very interesting study in that directory that shows detailed research that "innie" mounted windows perform much better than "outie" installed windows. Here in the USA outies are 99% of the installs. In a Passive House design in Europe, innies are 99% of the installed windows. The performance gains are quite substantial. They have even had identical homes next to each other, one with an outie design and one with an innie design. The outie window experienced frost conditions while the innie did not. They also recorded greater energy loss in the outie windows.
