A super Insulated House and a very poor insulated House.

Massive heat lost on windows and through walls for sure not a Passive House.

Passive House: Comfort through Efficiency

The Passive House is the world’s leading standard in energy efficient construction: Energy saved on heating is 80% compared to conventional standards of new buildings. The energy requirement for heating is lower than 10 to 20 kWh/(m²a) (depending on climate), adding up to a low cost of 10 to 25 € per month. Therefore high energy prices are no longer a threat to Passive House occupants.  Exceptionally efficient components and a state of the art ventilation system, achieve these huge savings without compromising comfort, but rather increasing it. The Passive House concept is a comprehensive approach to cost-efficient, high quality, healthy and sustainable construction. The concept is easy to understand: Contemporary construction is quite airtight, therefore the air replacement from infiltration is not sufficient. Ventilating by opening windows is not a convincing strategy either. Getting a sufficient volume of fresh air is not just a question of comfort, but a requirement for healthy living conditions. Therefore mechanical ventilation is the key technology for all new construction as well as refurbishment of existing buildings. Mechanical ventilation will work in all cold and all hot climates since in an airtight house, the heating and cooling energy required will be significantly less. Even though mechanical ventilation systems raise initial investment costs, if designed efficiently they will reduce energy costs significantly, eventually paying off the initial cost.Ventilation units suitable for Passive Houses allow for an economic operation. Now we explain the central "trick" of the Passive House concept: The fresh air needed is entering the room anyhow. If one could use this air to cover the heating load, without increasing the mass flow, without recirculated air, without noise and without drafts - then the ventilation will pay off a second time. This concept of "fresh air heating" is only possible in a building with superior thermal insulation, just like a Passive House. For experts: This is the defining requirement; the maximum heat load should be lower than 10 W/m² , allowing the fresh air to carry the heat load. Passive Houses require superior design and components with respect to: insulation design without thermal brigdes air tightness ventilation with heat recovery comfortwindows und innovative heating technology To realise an optimal interaction of all components, an energy balance of the building has to be worked out. And step by step any new design may be improved to meat Passive House standards. Thousands of Passive House dwellings are already occupied. Examples will be shown in workshops at the Passive House Conference: Design, redesign, create scopes of opportunity: architecture and the Passive House Passive commercial buildings A tour of the built  House will follow.

Walls have arrived

Our super insulated prefab walls from Ray-Core have Arrived at the job site. We are Ready for Building our super insulated Walls .

One 53' Trailer full of our Panels.

Offset 2x6" Studs to eliminate Thermo Bridging in the Walls R 52 Foam core insulation Ray-Core .

Wall Cross section for all Exterior Walls top view

The above Wall cross section shows the eliminations of thermo bridges by staggering studs and sill plattes and applying a continuant layers of Foam board over exterior surface of wall. Also there will be no switches or outlets, wires or pipes in the exterior wall surfaces. This New Wall construction has 20 times more insulation value with no Air leakage than the existing 12" Brick wall with 1" air space R 3 and plaster on inside. and is less in thickens.

Basement wall retrofit cross section

Well we are keeping the Basement walls and have add insulation on insite and outside to get enough R value to meet the requirements of our model from the PHp.

Super insulted prefab Wall panels

I am so ready to order the super insulated  wall paneles this week from http://www.raycore.com/wall.php
2x8 (7,25")walls Foam core  R 7 per inch with offsetting studs. for Main floor and second floor. Wich makes the Main walls R 52 in additions we will have 3" of Foam under the stucco finish adding another R 12 for a total R value R 64.
