Ask Slashdot: Shortcuts To a High Tech House
First time accepted submitter phaedrus9779 writes "I'm a recently married man about to take on the next big adventure: home ownership! I came across a great house in a great community but I need a little bit extra: a high tech house. The problem: money, I'm on a budget. I'd love to have home theaters, super high tech weather stations and iPads seamlessly installed in all the walls — but this just isn't possible. So my question to the Slashdot community is: how can I build a high tech house that will be the envy of my friends, provide lots of useful gadgets, and not break the bank? Also, as always, the cooler the better!"
Two items I can recommend that cost a bit upfront but do indeed save money down the road:
- Nest Thermostat ( http://www.nest.com/ )
- Tankless water heater
A good tankless water heater will cost a few K (with installation, etc...) so perhaps just start with the Nest. There is currently a waiting list for them, but I was able to get mine about 3 months after waiting. It looks cool, and if used properly, will continually save you money over the life of the house.
Pay off at least part of the house before you add frivolous crap to it to impress your friends. I have always been more envious of people with a paid-off (or at least non-defaulted) mortgage than I have of those who have 5-year-old technology pointlessly glued to the walls. You get to choose which of those you have in 2017.

Seriously, I've never understood all the horror stories, not before and not after my own marriage.

I don't think that you understand American culture very well. This isn't about the house or the gadgets or the technology. This is about the American male having a higher debt load than his friends and relatives. That's what really matters in America. The bigger your debt, the more American you are.
When an American says he "owns" a house, the house is secondary. It's the $400,000, 60-year mortgage that's important. His neighbor maybe only has a $350,000, 40-year mortgage on his house, so his neighbor is clearly the inferior being.
Then there are the American's car loans. Many American couples own three or four SUVs or trucks, because that way they can possess more vehicle loans, each for a greater amount. You don't want to be the only American on the block with one or two cars! That'll clearly show that you're scum.
Credit card debt is also a very important indicator of how American somebody is. If you've only got one credit card, you're probably just trash. You're worse than trash if you haven't been paying at least some interest on the balance for a few years. Real Americans will have maxed out at least four or five credit cards, while working hard on maxing out the sixth, seventh and eighth that they possess. Buying the overhyped Apple useless-gadget-of-the-hour is a great way to achieve this goal.
I hope you have a better understanding of American culture now, and the utmost importance of debt. No American household is complete without owing huge amounts of money to some faceless corporation, especially when there's no hope that they could ever repay it during their lifetimes.
If you DIY you can probably accomplish a lot for under $10k and the pros would probably charge you 10x that for similar functionality. The following categories should represent the major considerations:
Infrastructure - How are you going to connect everything?
- WiFi Everywhere
- Server box for storage & to run some home automation software & scripts (small embedded linux or more powerful)
- Main equipment location & as much distributed wiring as you can do cheaply & easily yourself
Entertainment - From where will your source content & how will you present it?
- LCD/Plasma Monitors
- Multiroom audio
- Rokus or other cheap streaming boxes?
- Whole House DVR systems from cable/satellite? (Dish Hopper/Joey, etc...)
- HDHomeRun or other DVR capture cards?
- A/V matrix switches & distribution? (monoprice)
- Programmable remotes (ipads, cheap android tablets, logitech harmony, etc...)
Comfort & Convenience
- Lighting (X10, Z-Wave, Insteon, UPB, etc..)
- HVAC (thermostats)
- In-house communications (intercoms, pbx)
- Misc automation (window shading, garage doors, locks, etc...)
- Weather/Environmental sensors (oregon scientific, lacrosse)
- Programmable remotes (ipads, cheap android tablets, logitech harmony, etc...)
Security
- Alarm system (2gig, honeywell, etc..)
- Cameras & DVR
The wow factor usually comes from complex actions resulting from simple inputs (scripting) so plan ahead for how everything is going to work together & communicate (sticking to fewer protocols will be easier, though maybe not always cheaper). Have a controller/server you can program yourself and don't get locked in to a proprietary system.
IMHO, a bunch of ipads plastered into the walls really aren't that useful or impressive so skip that.
Make sure whatever you do, it's wife-friendly (unless your wife is an uber-geek).
If your wife is typical, when she wants to watch TV she wants to press "ON" on a remote, then select the channel that's running Glee. She doesn't want to boot a Linux box, mount a fileshare and browse a bunch of torrents. Similarly, if the house is cold she wants to bump up the thermostat, not telnet into the furnace from a PC that doesn't have a case that lives in the garage.
You'll get plenty of suggestions as to what will ostensibly save money down the road. Carefully analyze it FOR YOUR SITUATION. Sometimes, the comparison in the literature is today's whiz-bang gadget against "the average widget" in the entire US. Look at your energy and resource costs and environmental conditions in your area (Im in SoCal is different than coastal Maine or Minnesota) Examples from a house built in 1997-1998
Cases in point:
Tankless hot water. - Right now, natural gas is *cheap* and it is likely to stay that way for at least 10 years. If you have (or are going to have) children, you consume a lot of hot water, all at one time (yes, 2 teenage daughters, etc.). Tankless is great for one person at a time showers, not so hot for laundry+2 showers+ dishwasher, unless you radically scale up. And conventional tanked hot water heaters these days (with insulating blanket and modern ignitors) don't burn that much gas "keeping the tank hot". (and you could always put a timer on the burner to shut down during the middle of the day). Ditto, solar panels. Today, gas is so cheap that the payback period for solar panels is decades And the maintenance for the panel system is bigger. If I had to make hot water with oil or coal or (god forbid) electricity... it would be different.
Electrical power - in my house, in the winter, the two big loads are: refrigerator, lighting. But lighting is only when people are home in the evening. I had all sorts of plans for automatic timers, etc. But a bit of measurement (Kill-A-Watt on the refrigerator, TV, etc.) showed that lighting was less than 20% of the total load, and fancy switching might reduce that to 15%. Summer, the big load is AC. But that's mostly determined by factors beyond my control (e.g. the outside temperature). A higher SEER AC might help, but running the statistics showed, not really, for our area.
Appliances - Front load washing machine is *a lot* better than top load in both water and electrical consumption. But, how long is the payback period on a $1000 purchase? Refrigerator.. same sort of thing. If your refrigerator was bought in the last 10 years, the new ones aren't *that* much more efficient. If you're using an avocado colored beast you got from your parents 30 years ago... yeah, a new refrigerator might not be a bad idea. But again, you're talking $1000
Insulation - i wanted to aircondition my garage to make it comfortable in the summer to work out there. So I immediately assumed I'd need to go on a insulation frenzy. But a big of calculation showed that running the airconditioner the few hours longer to make up for the poor insulation would cost something like $20-50/year (it's just not that big a space 20x20 ft, and the number of days/hours when the outside air temp is above 80 isn't all that many). Am I willing to invest several thousand dollars worth of time to go through the process of insulating.. nope.
Moral of the story.. don't take the "conventional wisdom" as the analysis. Your situation, and your power rates and climate, will be different.
