Thanks Toggleswitch for the suggestion of this thread. This is a fantastic site for sharing information.

I live in a house built in 1797. The interior walls are thick plaster and ceilings of various heights. The house was built by a fellow who served with George Washington in the American Revolution, Dr. Timothy Rossiter. He sold the house in 1811 to a family that kept it (through material lines) until I bought it two years ago. The house was pretty much intact as it was in 1805.

When I closed on the house I was facing a major restoration effort. The plumbing and electric was installed in 1910. I replaced those systems this past spring (I replaced the 1910 installation). I did not install central heat or air conditioning.

This past summer in Georgia was a record heat wave. Some days got up to 105! My house inside stayed under 75 degrees! This is what I attribute it to; first the house faces South and catches morning sun on the east side. I kept the shutters closed in the first half of the day on that side of the house. In the afternoon the sun was really hot and bright. I kept the shutters closed on the west side of the house (and the louvers open somewhat)in the afternoon hours into night.

As in the 19th century I take up the persian rugs and take down the drapes. The house has a center hall so the doors may be opened for fresh air and light as needed. Yes, the house stays a bit on the dim side in the summer inside.

But it stays very comfortable. When it is hot outside (90 plus )my home is cool and inviting.

I have not made any big changes in the house. Nor did any previous owner. The house is pretty much the way it was in 1805 in almost every detail except for the update in plumbing and electric.

My neighbors also have old homes (the entire town is comprised of antebellum and victorian houses). Most have installed central heat and air. They pay an average of $480.00 a month to heat and air-condition their homes.

My summer gas bill ran me 13 to 15 dollars a month this past year. My winter bill, with gas logs in the fireplaces...and I only heat the room(s) I am using might get up to $100.00 a month. I paid $33.00 last month.

Now, after all my rambling...Would any of you guys install central heat and air conditioning in the house? My neighbors think I am off my rocker to live by 19th century standards.
I am saving a boatload of money. I don't understand why they want to air-condition and heat every inch of their house???

I tend to lean toward 18th and 19th century ways of living but I am taken with some of the new inventions. I have to admit I bought solar outside flood lamps and put them outside during the day. I bring the lights in at night. A great way to light the house without turning on an electric switch.

My kitchen is the old kitchen house that was moved up and attached to the house in 1910. I have a modern electric range in use at the moment but I would also like suggestions about how to update the kitchen with old appliances if possible.

When I bought the house the kitchen it had a 1972 kenmore stove that was rusted out and not working. No fridge. I could see ghost lines for a wood stove along the walls.

The laundry was always sent out so I have a pretty free element to work with there. I think I want to put a stack washer/dryer in my bathroom.

OK guys, I welcome your suggestions/questions. I appreciate your help.

Old old?
Or modern that look old?

 
Plaster Walls

My dad's Cape is all plaster walls and the downstairs is as cool as a cave in summer, so much so that it doesn't trip the thermostat on the A/C to cool the upstairs, and as you know heat rises. It can be 71 on the main floor and 81 upstairs, albeit Cape Cod homes are hard to cool the upstairs.

Something to be said about those old plaster walls versus the gypsum crap put up now.

Before we had A/C, my mom used to follow the sun and close drapes and shutters and our main floor was really cool even on 90 degree humid days. We had a screen back porch with daybeds and lounges off the kitchen and we kids would sleep out there when upstaris was too hot.

I'll bet if we had an attic fan thing, we could have slept upstairs in 90 degree weather. There was just no place else for the heat to go. If we could have forced the second floor heat at the ceiling to go to the small crawlspace above and out the soffit and gable vents, it would have been fine.

Anyone have an attic fan? How do you insulate the louvers in the winter when you don't want the heat to go out the hole in the ceiling to the attic?

Attic fans seem to be a thing of the past, but with energy costs, could they not be re-utilized, especially in seasonal heat conditions?
 
If it ain't broke, don't fix it. If there are no other people living with you, and you're able to feel comfortable, I'd leave everything as is.
 
These old homes are built of real timber, inside and out. Not the faux clapboarding and gypsum that is standard today. Timber is a very efficient insulator against cool and heat. Having high ceilings also helps during the hot months.

What you are currently doing, I have observed amongs the older generations over here. Many grew up without airconditionning and their houses had shutters, heavy drapes, timber floors and sleeping porches for those really hot nights. Even now and with airconditioning in their homes, many will keep drapes drawn all day to keep out the heat and live in a kind of summertime gloom. Unfortunately it isn't quite as effective as modern houses are ususally designed with artificial heating and cooling in mind.

Personally, I dislike airconditionning. I spend a lot of time in the tropics and find that a ceiling fan does very well for me. I reckon in your case ceiling fans are probably the ideal solution. I understand that Georgian winters are short, but damp. If you are getting by with your gas fires in winter, a reversable fan will circulate the heat down from those high ceilings and get it even cosier for you. In summer it will suck any heat right up to near the ceiling and provide comfortable air circulation.

Thanks Toggles

I think we need to look for more low tech things to help our energy consumption. I have seen homes with a second floor scuttle door converted to a ceiling fan adaptation in California, but not here in NY State. I am envisioning a hole at the top of the stairs second floor 18/18 inches or so that would have a fan attached to suck up and capture the rising heat as it comes up the stairway and send it through the soffit and gable and ridge vents before it sits and heats the upstairs.

What do you think?
 
Another thing we see a lot of in Australia are whirlygigs. They are roof ventilators designed to expel the hot air that accumulated in attic and roof spaces and create continuous airflow. I don't recall seeing many of these about in the US - am I right? Anyways, a link is attached for your info.

 
Whirlygigs

I have seen them in the US occasionally, mostly on barns and commerical buildings.
We have far to go here in terms of going green. I am sure they are not code in Beverly Hills nor Coral Gables nor Manahttan for residential use,but wouldn't it be great.
Energy for us has always been relatively cheap in the US, but things are changing and people's attitude twords the middle east war and the US oil and energy companies exploits are creating a much Greener America! Yay!
Let's buy something that screws the Arabs and the US Oil and energy companies out of a few bucks, and little by little, the customer of energy has more choices to diversify and save.

We have major opponents of wind energy here, especially off the coast of Massachusetts. They feel the windmills will ruin the view off Martha's Vineyard. F*** them. The same liberal rich who live there in Camelot are complaining that lives are lost in Iraq fighting for oil. They should be putting whirlygigs on their roofs and a windmill on their beach if they want to save some lives overseas so we can let the middle east dry up to the tribal desert it once was. Let them beg us to buy their oil, at a buck a barrel.

But that's just me.
 
~Some days got up to 105! My house inside stayed under 75 degrees!

Heck, no! Don't spend that money. I keep my house at 76 degrees in hot humid SE Texas and it feels fine (I also run a dehumidifier). If you have one or two problem rooms, get a window unit, or just go with fans/ceiling fans.

If these are the same things we call "turbins" we have a lot in Texas, although the current fad is to install ridge vents when a new roof is put on the house. I ridge vents and I also have an electric gable vent fan that is set to turn on at 105 degrees.
 
Whiel teh SF Bay ARea is known for its mild climate, there are a few days every year when the temps get up into the high 90's to low 100's.

This home was built in 1941 - the main part of the house has plaster walls - the exterior is mostly stucco. There's a master bed/bath addition incorporated into the rear of the home (undetectable from outside) that is stucco/insulated sheetrock. The roof is wood, and all the windows have fixed shite aluminum awnings.

When I bought the place in '97, the attic was completely uninsulated. Despite having a thick cedar shake roof, the home got very hot during the heat waves. You could feel the heat radiating down from the ceiling.

After I put 8 inches of fiberglass insulation in the attic, and added soffit vents, things changed dramatically. I found that if I used fans to blow cool air into the home during the night, and then shut up the home during the day, it would easily stay cool and comfortable until nightfall.

This past summer the local utility company was offering $50 rebates for every energystar window A/C unit purchased. I got two small (6000 btu) units for something like $100 each. In effect they cost $50 each. I installed one in the middle of the house, in an open area shared by the kitchen (refrigerator puts out heat) to help out on the hottest days, but really didn't find that it was all that great, but it helped a little. As soon as the outdoor temp dropped below the indoor temp, I'd shut off the AC and switch to fans blowing outside air into the home. I still haven't installed the other one, but it will probably go in the master bedroom.

Bottom line: I wouldn't install central A/C in your home. If you can keep it at 75F during a heat wave, that's as good as if not better than the government says you should run A/C. You might want to consider, however, putting in a window A/C unit in the areas of the home that produce heat, such as the kitchen. Especially after you start adding more appliances - like a dishwasher - that will add more heat to the kitchen.

In that regard, you might try to get appliances that are as efficient as possible. An induction electric stove will add the least amount of heat to the room. A european style dishwasher with condensation drying will add less moisture to the house and a vented dishwasher. Of course, a modern fridge will use 1/2 to 1/3 the amount of electricity as one from the 80's, and that also means less heat.
 
If you're comfortable enough I wouldn't bother. If anything for the bedroom or other rooms get a portable air conditioner with the two hoses to the window, simple to setup, simple to remove in a minute or less and hide away in a closet. They don't look that pretty sitting in the room but then you don't see them uglifying the house from the outside like a window a/c nor do they block out as much light as a window unit, it's a trade off but no alterations required.
 
with the conditions in that older home-you don't need AC-the old house was well designed to use min energy in the first place.AC and central heat wasn't necessary-or available.Wish mine was like that.In the summer at my place the AC cranks away-and cranks up a bill!But my house would be unbearable without the AC.
 
To Greg

I'd be so proud of getting a house like that...
Actually we are looking for somewhat equal here in Germany...but not easy to find...

My advice, as I studied five semesters of architecture once, never try to renovate or "modernize" an old building! Means: do not try to make something else out of something that it isn't made for! Only REconstruct and RESTORE things in it, keep as much as possible and care for the old thing and it will last for ever!

If you force something into it or try to make something else out of it, it will end up in a desaster!

Old houses have their own abilities but they will NEVER become a modern building - and you should be glad for that! They have so much more to give compared to a modern house!
And I would be so proud of having an ability to live a different way of live than all the others...
