Where to put the microwave?

Locating a microwave in a "luxury" kitchen is difficult because a main feature of a "high end luxury" kitchen is that it does not follow convention of putting in an over the range unit-as it would interfere with the aesthetics of the expensive fume hood. Does anyone have any original ideas for locating one that is ergonomically and aesthetically pleasing in the below kitchen that calls for one of those pesky microwave units? I have included a sketch of the kitchen. The yellow area is going to be a glass wall with a door---so that part is out.

Pipe out through wall or rim joist?

I need to get a PVC pipe out from the garage. Can I just simply run it through the wall or does it have to go through the rim joist? What would be the benefit?

Does ASHRAE’s Residential Ventilation Standard 62.2 make sense in a cold climate in a pretty good house?

I'm designing a pretty good home (R33 walls, R60 ceiling, R7 windows and less than 0.6 air changes per hour at 50 Pascals pressure) in Zone 6 and I'm trying to configure a balanced ventilation system. I read several Green Building Advisor articles on mechanical ventilation, including "How Much Fresh Air Does Your Home Need?" which pointed out the potential for moisture issues in warmer climates when designing to ASHRAE’s Residential Ventilation Standard (Standard 62.2), which sets the minimum ventilation rate at 7.5 cfm per occupant plus 3 cfm for every 100 square feet of occupied floor area.

Add insulation when changing siding?

We are getting our windows done on our 40 year old over the next month (yes they are the original windows LOL). We currently have 2x4 walls with full insulation, zone 6 climate. Has anyone ever increased the insulation R value by adding styrofoam? We are residing the house within the next couple of years.
Thinking about adding 2 inch foam around 3/4 of the house (front wall is brick) just not sure if the cost recovery will be worth it (not to mention the difficulty in matching the wall that meets the brick wall due to the extra 2 inches). It looks like a 48x96 sheet will run $60.

Tiny house exterior foam sheathing and insulation question

Hi, I am currently building a tiny house on wheels and have just about finished putting up the cedar lap siding. I just found out I may be in violation of a building code for my tiny house. Due to weight issues my dad and I decided to use insulating foam board sheathing for some of the exterior walls. The front and back as well as the corners were all constructed with plywood sheathing but in between we thought it would be best to use foam board. (We used foam board sheathing in the void spots in the picture below)

Interior vapor barrier for old house?

I have a hundred plus year old building (originally single-family, converted to three-family) on Long Island (Zone 4A) that has a mix of 2x4 framing (balloon & other), with 1" nominal (minimum 3/4", to 7/8") tongue & grove wood sheathing underneath clapboard that's covered with aluminum siding.
We're going to remove the clapboard & aluminum sidings, keep the sheathing and cover it with Tyvek, 1" foam (polyiso or XPS) and vinyl siding.

DC solar water heater viable?

I live in a state that makes it very hard to grid tie to utilities. On a duplex I own it has two 50 gallon electric water heaters. One for each side. My thought is to offset the over $1000 a year that it cost the renters. Its in a zone 6 so a normal solar water heater wouldn't work. Gas and renters do not mix so gas solutions are out of the question. The heat pump water heaters don't have enough space to operate, make noise and more likely to break down.

Not a question but a thank you Martin, Dana, et al.

Although our own project has been suspended indefinitely I've been exposed to a tremendous amount of information regarding building science and for that I say thank you. This site along with the sister sites are a great asset to the layman such as myself. May you all have a great 2016!
