AAC can be cut, drilled, nailed, grooved, routed, shaped, sculpted, carved, coated, floated, screwed into and milled with common tools. AAC anchors can be hammered directly into the block work and AAC fasteners can be utilized for a wide variety of commercial and residential decorating applications.
AAC has exceptional thermal insulating qualities. An E-Crete wall provides solid insulation, without the thermal bridging (cold spots) associated with through-wall framing members or fasteners.
Buildings constructed with E-Crete tend to be cooler in summer and warmer in winter. As a result, the building's air conditioning or heating use may be lower and makes the use of additional thermal insulation unnecessary. Customers reported lower utility bills.
In addition to greatly moderating the interior temperature, this lag time allows energy consumption to be shifted to off-peak hours, a benefit to power companies. In many temperate environments, an 8-inch-thick AAC wall provides more than the required thermal protection without additional insulation. Better temperature and humidity control provides greater comfort for building occupants.
A test was done on a 10" AAC wall. The outside of the wall was painted black to maximize heat absorption from the sun. A thermometer was placed on the exterior and interior surfaces of the wall to measure its temperature changes over a twenty-four hour period. The exterior surface fluctuated over 126 degrees farenheight while the interior surface fluctuated only +2 degrees farenheight.

I have "discovered" this house today. I had never heard about the Pieper house before... The current floor plan shows a single story small house but the pictures shows a bigger house with two stories... it seem that with the addition we can't consider Pieper like a Wright's house no longer..?SDR wrote: ↑Mon May 09, 2011 1:53 pm

These pictures of the Pieper house were taken in September 1996 while the house's addition and remuddling were underway. The contractor let me wander the house freely. During the hour or so I spent there, I got a good sense of how a Usonian Automatic was assembled by watching portions of it be disassembled. The house interior was stripped of all casework, fixtures and appliances, and a new drywall ceiling had just been taped and spackled. According to the contractor, all steel sash windows and doors were to be sandblasted, reglazed and reinstalled...reinstallation was underway in the fomer bedrooms...living room had not yet been touched. The addition (3 or 4 times the size of the original) connected at the northeast face of the original where the bedroom "tail" met the living/dining "head". The stacked blocks were those removed for the connection. The exterior of the house (except for the window blocks) was to be covered with EIFS to introduce wall insulation to the single wythe only UA construction. Apparently, the house was a true prototype in that it had single wythe walls and a wood framed roof. Some surfaces of the block had received a milky gray cement wash intended to provide a uniform/finish color...the tan color seen on most surfaces was the original color of the block/house interior. The house had an intimate feel, and the block and windows created a strong rhythm that distracted me from the rather "rough" character of the "unfinished" concrete surfaces. The lack of insulation in the walls...single thin concrete membrane...led the interior to be quite hot, as it was mid-day with a temperature of 98F or so; it made me want to build a white canvas tent over the house to shade it.
Looking back on my visit to the house I find its loss even sadder now, knowing how enjoyable it is to live in a spartan example of Wright's late work. The Pieper house was a rare insight into the experimentation that went on between the textile block houses of the 20's and the more polished Usonian Automatics of the '50's.

Additions to Wright houses are a problem for researchers. I don't know of a single resource for plans of houses as they appear today. Storrer occasionally shows expanded plans, but only where the addition(s) were designed during Wright's lifetime.

One would have to hunt for FLW in that confused mess.
