2 NOBLE HOME MODEL Z OVERVIEW Noble Home is pleased to now offer a net-zero model for customers who would like to further reduce their energy consumption. Our model Z net-zero home includes the features of our original homes while incorporating additional energy saving measures to make it suitable for near- or net-zero energy use and even off-grid living. Like our original models, the Noble Home Z is affordable and healthy. There is no plywood, OSB, or other off-gassing materials, and all of the wood is locally grown and milled to attain a chemical-free interior. The kit is shipped in panelized and pre-cut elements which can all be assembled on site with a minimum of skilled labor. Net-zero energy consumption is reached through a tight, highly-insulated building shell, passive solar heat generation, and solar hot air heating panels. We specify LED lighting along with energy efficient appliances to keep electrical demand low enough for the photovoltaic array to meet. As a result, the house can either be grid-tied or else tied to a house battery storage. Noble Home Z retains the timeless elements of our design while advancing the modern mandate of smart and efficient energy use. It is rooted in an honest appreciation for the natural world a house that is intrinsic to, and treads lightly on, the land that supports it. DESIGN Illustration 1: Interior of a typical Noble Home. Rafter tails and clerestory windows are replaced with a solid soffit in the Noble Home Z As with our original models, the Noble Home Z is custom designed and site-specific. This allows us to take into account the characteristics of the land the views, solar exposure, topography, etc. resulting in a house that is organic to its building site. The construction and interior of a Noble Home Z is very similar to our 20' and 16' models. A distinct design change is the removal of the rafter tails and clerestory windows from the original models. A more modern, better insulated overhang takes their place in the model Z, so that heat loss through these

3 elements is eliminated. The roof pitch allows for an overhang that properly shades the interior from summer sun while admitting passive solar heat in the winter. The illustration below lists the significant thermal components in the kit and the how the overhang admits or blocks the sun's rays in a northern climate. PASSIVE SOLAR HEATING Solar heating with the Noble Home Z is primarily accomplished through passive means. Since the 1970's, this has been a proven method of heating a building. This method consists largely of south facing glass to admit the solar radiation in the winter. In a conventional wood framed house with ample glass, the indoor temperature can become too excessive when the sun is shining and cool down quickly at night or when there is cloud cover. Therefore, thermal mass is often employed in some manner to absorb this additional heat and release it when the indoor air temperature drops, ultimately maintaining a more stable thermal environment. A cost effective way to do this, often used in Noble Homes, is to build the house on a concrete floor. Other methods include trombe walls, underfloor rock storage, and water bottles. In addition to our sliding glass doors as south facing glass for sun insolation, Noble Home has developed Hot Air Panels that can be fixed to the south wall of the home to aid in solar heating, without the drawbacks of significant heat loss through glass at nighttime.

5 GETTING YOUR NOBLE HOME Z If interested in pursuing a Noble Home Z design and purchase, here is a brief overview of the process: PRELIMINARY COST ESTIMATE: Provided to you based on your requirements submitted via the website contact form or Space Program form with the accompanying building site documents. A single level standard Noble Home Z kit will cost $65-70 per square foot. NAPKIN SKETCH SERVICE (optional): A deposit on the kit is required before beginning the preliminary design phase (see below). Our sketch service provides you with the opportunity to see a sketched out design before committing to a purchase. See example LOCATION. Cost: hourly design fees, typically totals approximately $300. This cost is deducted from a future kit purchase. PRELIMINARY DESIGN: We work with you through this phase to refine a design to meet all of your home ownership dreams. It is up to you how involved you are in this process, we welcome any degree of collaboration with you on the design. The design must be approved by you before continuing into the construction drawing phase. CONSTRUCTION DRAWINGS (CDs): Engineer-certified drawings specific to your design to be used for building permit acquisition and house construction. Guaranteed to meet local building codes. Cost: Design and CDs are approximately 10% of the Preliminary Cost Estimate. This payment also serves as a deposit to hold a position in our production schedule. This phase may take 6-12 weeks depending the on size and complexity of your design. After you approve the CDs, we will send you a Kit Purchase Agreement including a guaranteed kit purchase price, a list of all components included in the kit, and an estimated delivery date. KIT PRODUCTION: After the agreement is executed and we have received your first 1/3 rd payment for the kit. The production may take 6-10 weeks.. You may acquire your building permits and start your site work and foundation during this period. We will send you a customized Noble Home Assembly Handbook.
