In your reply to Brad's comment, This most definitely will work with a Slab on grade, with heavy insulation levels on the exterior of the slab. That is why i have developed it... it only takes up another 3" of wall space on the inside of your structure than a typical 2x6 frame.
The windows are best installed In the center of the insulation layer of the wall. Poor installation of windows can decrease the effectiveness of the window immensely. (up to 50% less effective in a passive house, due to poor window integration with the wall)
The roof will be ventilated as per normal, it will have a 1-3 inch air gap on the top of the insulating layer to let it breathe through the soffit. depending on what insulating material we use will depend on how we accomplish it.
A little bit on terminology.
R Value (the most common of what you will hear spoken at your local building supplier) as defined by Wikipedia The R-value is a measure of Thermal Resistance, Under uniform conditions, of the materials in question. (basically how well a material resists the flow of heat from one side to the other)
R values are often given to a materials such as R4 per inch is type 2 Styrofoam. The Higher the R value the better.
The only problem with using R values to evaluate how walls perform is that walls are usually not just made up material, they are carefully put together and designed to balance structure and insulation so we need to classify our walls as a whole unit rater than individual parts.
U-value (or U-factor), more correctly called the overall heat transfer coefficient, describes how well a building element conducts heat. It measures the rate of heat transfer through a building element over a given area, under standardized conditions. The usual standard is at a temperature gradient of 24 °C, at 50% humidity with no wind (a smaller U-value is better).
Taken from Wikipedia http://en.wikipedia.org/wiki/R-value_(insulation)#U-value
Basicly U Values are assigned to a material or a group of materials, Walls/Windows/Glass/Window frames etc and oddly the smaller the U Value the better. preliminary results/modeling put my walls at around a U value of 0.1025 witch translates to R 55
The rate at which heat is transmitted through a material, measured in watts per square metre of surface area for a temperature gradient of one Kelvin per metre thickness, simplified to W/mK. The Lower the value , the better the thermal efficiency of the material .
Lambda values are what is imputed into the PHPP (passive house planing package) software when calculating U values for walls etc. and each materials has a specific value.
