3 How to get started with an MHS Building System Project? Sign an MHS Non Disclosure Agreement. Enter a Project Engineering Consulting, Architectural Design Agreement. Structural Calculation Agreement. MHS prefabricated component purchase agreement based on approved design. Local Contractor Training and site Assembly Supervision Agreement. What is the biggest challenge facing the Building industries worldwide? Our philosophy behind MHS building system is : The art of post and beam framing, simply light buildings of prefab modular technology. This has reached the latest design throughout the green building system. Winner of numerous awards for function and design MHS Building System believes development will not stop here. Staying true to conventional post and beam framing has allowed us to always adapt to the times and overcome new challenges. We are faced with the most urgent demands for energy efficiency. To fulfill our responsibility as well as protect the environment and climate we at MHS Building System offer advanced solutions by providing a cost effective and sustainable aluminum frame of modular technology. What are our Products? MHS extruded aluminum framing system Structural MHS building components, connectors, foundation steel base plates. Hybrid Aluminum, Metal Structure SIP or FSIP wall, roof, floor panels (insulated EPS panel) Magnesium board panels Aluminum cladding extrusions, MHS Alu roof joist framing, Indirect lighting, MHS louvers We deliver to the construction site an MHS framing envelope, prefabricated and ready for assembly. After framing installation all that is left is to finish the house with an approved local contractor.

4 During the Design Agreement with careful consideration of budget a list of windows, cladding & doors will be approved and ready for the final step. You and the local contractor will either order directly through vendors or our design office will do. This method gives you great freedom on exterior and interior design, allowing you to choose the finishes that best compliments your lifestyle and budget making your home yours. Our expert design team work diligently to control the cost of the project allowing you to develop an affordable sustainable MHS house. How much does a MHS House cost? It is hard to say, because of wide variances of import costs of materials and labor; we cannot estimate a finished price. We can provide you through your design document the cost of MHS structural framing envelope (prefabricated components).

5 Exterior and interior finishes and installation shall be estimated by your local contractor. MHS concrete foundations will be reviewed by a local structural engineer or provided by MHS based on our MHS technical details, according to load tables and local building codes. For example here is our general cost based on a past project, MHS General Components for MHS building envelope Cost about ($50 $65 per Sf). MHS framing items used on MHS Building Cost Per SM FOB China plants 1 Aluminum Extrusion MHS 170 $ per SM of Building 2 MHS Components $ per SM 3 FSIP (sandwich panels) $75.00 per SM 4 Workshop Pre Fabrication cost $50.00 per SM 5 Water seal insulation $20.00 per SM Total MHS structural Envelope (no assembly) $ per SM + Project design & Consultant fee What about Interior, Exterior Cost Estimate? Exterior, interior finishing will vary based on Location, materials chosen by designer and according to project budget. Electrical, mechanical and foundations start around $ Per SM. Approved Local lisensed contractor will list the items needed based on the projects architectural design. (Note) Local cost and labor for MHS is almost lower than any other building construction. Your local contractor based on the labor cost and local green finishes will provide better cost estimate for finishing and foundation. Typical cost of MHS framing envelope components from our China factory FOB is $ per SM of the standard contemporary building with flat roof. MHS framing envelope from our Long beach California U.S.A. plant: Please add about 20% to the general cost. Please note all interior and exterior materials used with MHS building system must be approved by MHS consultant and MHS project design office. Can you provide A Z on a project for us? Yes, MHS will sign a contract for a complete MHS building start from design and the engineering needs in the first step.. Our group enables us take responsibility from A Z of single family home up to multifamily housing projects worldwide. Our MHS Engineering teams have the ability and resources in China, USA and UAE. Working directly with project owners and project decision makers allows executing our construction agreements and starting the process immediately. (Project Brokers, MHS sellers or design offices that use MHS Technology work with in their commission and pre selling agreements). Why modernist MHS prefab? Predominant mass market housing programs such as project homes or tract housing largely fail to meet the desires or needs of people who appreciate a modernist design aesthetic. Custom designed modernist architecture is

6 beyond the financial reach of many people and so prefab is viewed as a design and production ideology that has the potential to deliver affordable modernism. MHS prefab homes are available in many forms and designs. What are the advantages of MHS /SIP construction over conventionally framed buildings? MHS homes, made with MHS Aluminum Framing and Structural Insulated Panels, can be erected and assembled very quickly and with zero waste. MHS walls, roof and floors provide tremendous interior design flexibility. They also produce a stronger building envelope vs conventional stud or steel stud framing of equal thickness; in addition they are extremely energy efficient. MHS Building Technology Provides Custom Design Flexibility High tech Engineering Services and Solutions completed with state of the art software Prefabricated Posts, Beams, and Connections Factory Finished Panels Modular Site Installation and Assembly Hand tools, safety equipment, design plans, and components Resourceful Cost Benefit Building Technique Energy Saving Sound Efficient Quick & Dry Waste Free Construction Super Strength and Durability Constructed To Meet Local Building Codes Maximum profit from local resources, site accessibility, and Labor. Endless possibilities for Architects to realize individual design possibilities Consistent quality and durability Builder profitability and satisfaction amplified Fire resistance Earthquake Responsiveness International Logistics

7 MHS Mobile Villa Beijing (Under Fabrication) What is the R Value of the SIP panels? R Value=the efficiency of insulation of a house (Thermal conductivity) 4 R Value 15 6 R Value 24 8 R Value R Value R Value 47 Note: If higher R values are desired, Our designer can add another layer of the SIP or FSIP to the roof or walls In addition to superior energy efficiency the MHS Wall, floor and Roof Panels consisting of SIP or MHS FSIP'S* they provided great insulation and sound control as well benefit the costs of the project. *MHS FSIP (Flameproof Structural Insulated Panel) What kind of foam is used in the panel? Expanded or Extruded polystyrene can be used with MHS panels with approved APA as a sandwich panel. FSIP

8 Is there any formaldehyde in the foam? EPS does NOT contain CFC s, HCFC s, or formaldehyde. EPS does NOT contribute to the growth of mold or mildew. EPS is considered to be no more toxic than Douglas Fir wood under the worst case fire scenario. EPS is manufactured in accordance with ASTM C578. EPS is recyclable. What happens when the panels burn? The toxicity given off from our foam during combustion is about the same as that from wood. The key advantage of using FSIP panels. FSIP panels with skins of flameproof magnesium hard boards and EPS infill with covered edges and foam protected by the MHS framing channels. This delays the spread of flame. Blocking fire access to the EPS foam core slows melting and combustion. (Melting point of EPS is about 170ºF). In case of fire the buildings load carried by MHS framing has a melting point of 700ºF. MHS framing will retain its structural integrity in fire and not provide fuel to the fire. What are the building code requirements for panels relative to fire?

9 Building and fire codes vary from location to location. Usually, a 15 minute finish rating is required for light construction type 5 SIP panels, with an interior layer of 1/2" drywall. What is the wall finish fire rating of MHS Panel? The complete fire rating for the MHS FSIP is currently being tested yet preliminary test are showing about one hour. What is the energy efficiency rating of MHS Aluminum Framing? Percentage of the energy needed to manufacture all industrial raw materials, according to a 1987 study. Wood 4 Percent of Energy used Steel 48 Percent of Energy used Aluminum 2 Percent of Energy used, Is this good news for a healthy planet? Yes, for every ton of wood grown, a young forest produces 1.07 tons of oxygen and absorbs 1.47 tons of Carbon dioxide. Save a lot of trees in construction when using reusable aluminum alloys with 98% recyclability. Compare the number of trees we have lost during the last century to build new houses. It's said a squirrel could swing tree to tree from Maine to the Rocky Mountains when the pilgrims arrived. How about the Life Cycle? Life cycle of aluminum extrusion used as framing in MHS homes using less wood products from extraction of the raw materials to demolition of the building at the end of its extremely long lifespan is much better for the environment than steel or concrete in terms of using energy, air emissions, water emissions and solid waste production. For the complete details please refer to MHS sustainability report. MHS/SIP's are energy efficient and an efficient use of resources, making them an ideal choice for a high performance green building. MHS/SIP space frames have 90% percent less leakage and save energy VS stick framed rooms.

10 MHS/SIP homes can reduce annual energy use by 50% percent or more over the building energy code. Who takes care of erecting a MHS Framing Envelope? MHS trained and certified general contractors or FSIP's installer crews are responsible for MHS/FSIP erection. MHS can recommend experienced installers in many regions. What are the foundation requirements? The foundation installation according to specifications provided by MHS can be built on a slab on grade or on concrete walls, pillars or footings. The foundation is built within close tolerances by an approved provider, Due the accuracy of the supplied components, even slightest inaccuracies in levels or even being out of square can result in problems with framing erection. What happens if it rains while the framing is being erected? MHS/FSIP assembles are not damaged by rain. Building Installation can start any time during all four seasons.

11 Can I finish my own MHS home?

12 Depending on the fabrication and assembly agreement some can be complete by you. General and basic skills are required to finish your new MHS home. Homeowners may do most of the work themselves if they choose to, some subcontracting is required for electrical and plumbing work. How is the roof finished? Almost any light shingles or metal roofing is recommended to use. By following manufacture installation details. Green roofs can be used over the MHS roof framing system. Is exterior siding applied directly to the panel skin? A moisture barrier should be used between the panels and siding. An air barrier such as Tyvek or Grace Water proofing can be used. In most situations, especially such as with wide board and batten siding, wood strapping should be attached to the wall first, then the siding secured to the strapping. Are windows and doors difficult to install? No. Windows and doors are very easy to install in a MHS wall or roof. Units are set into the rough openings (which were built into the shell) and shimmed to level, as per instructions provided by the window and door manufacturers. Then the perimeters are sealed with low expanding foam sealant or TyveK Flashing resulting in an extremely energy efficient installation. Care must be used when foaming around windows and doors so as not to swell the casings. How are interior walls installed? Interior partition walls are generally constructed of 2x4s or just using SIP by itself and sheathed with drywall as in conventional frame construction. Where an interior partition wall meets an exterior wall, the edge stud is nailed or screwed into the skin of the panel.

15 A1 Office Building project Dubai How do you run wiring in panels? There are a number of options for running electrical wiring in a MHS frame. Horizontal wiring runs are usually carried under the floor or drop ceiling, Depending on the MHS foundation design and finishing over the FSIP. Before drywall is installed utilities can run along the foundation channel under the beams to anywhere in the building, easy access for maintenance. Keeping FSIP panels and Aluminum framing structure open to pass utility elements free is a major advantage. Refer to MHS project assembly manual and wiring details for more information. How do you run plumbing in a MHS Home? There are almost no differences between plumbing a MHS home and plumbing a conventionally framed house. Plumbing runs should be kept in interior (conventionally framed) partition walls or in specially constructed plumbing chases. How are walls finished in a MHS Home? Walls are usually finished with drywall on the interior face or other fire proof materials, on SIP walls; drywall is installed directly over the surface of panels, applied either vertically or horizontally. Some builders use construction organic adhesive in applying drywall to the panels, enabling them to use fewer fasteners.

16 How are kitchen cabinets installed? A1 Office Building project Dubai Kitchen cabinets are very easy to install in MHS WALLS. Along exterior walls, cabinets are screwed directly into skin of the panels. Because a single layer of FSIP is not as thick as a frame, you should use a few more fasteners. Screws are recommended for cabinet attachment. For the strongest attachment, cabinets should be secured directly to the FSIP skin and drywall. What is the best type of heating system for a MHS/ SIPs home? Any type of heating system can be used. Talk to your heating contractor or general contractor for recommendations as well as floors and wall heating system MHS SIPs homes are able to provide heat by using one to two cords of firewood per year! With wood heat, a source of outside combustion air is recommended. Can you combine MHS building system with other kinds of roof system? Yes you can, MHS modular wall panel framing system works easily with most other metal space frames for large span roofing system. Are you offering the Fabrication License and training for MHS?

How about the substantially of MHS Design and components?

17 The practice of sustainable architectural design attempts to reduce the collective environmental impact during the production of building components, during the construction process and during the life cycle of the building. The Modular Housing System from Unique Structural Systems is a pre engineered system using a variety of aluminum programming extrusions for post and beam framing connected by a patented, concealed bolt and clamp component. This is supplemented by bolt in place corner fixtures for multi story structures usually concealed within wall panels. The MHS sheathing system uses either Structural Insulated Panels (SIPs), FSIP or a combination of other panel materials which slide into the channels of the framing members. The system can be assembled manually with the use of a simple impact wrench and framing members connected anywhere along their length. This provides virtually limitless design options in any rectilinear configuration without additional demands on labor during construction as well as employment of local workers who can be trained in one day. The Modular Housing System's key characteristics of simplicity and flexibility mean this system is adaptable to any geographic, climatic or societal requirements with no waste or additional design constraints. Sustainability initially aims at minimizing the impact on the building site in terms of the land, topography, vegetation and view. MHS aluminum framing weight is 1/3 that of steel I beam framing and 1/24 of concrete. This eliminates the need for heavy equipment at the site, since one worker can carry a 12 ft MHS framing member. Compare this with placement of one steel I beam at the job site. The weight of concrete used in an MHS foundation is almost one half that required for a steel or concrete structure. Less weight during transportation of building components means less use of fossil fuel and lower shipping costs. Further, flat pack shipping of the MHS components provides substantially greater efficiency than transport of modular boxes. MHS components can be transported to any buildable site economically and utilize any foundation from piers to pad. As post and beam system the MHS offers wider spans with more glass increasing the option for passive solar heating or cooling while the thermal advantage offered SIPs provides less 'active' heating requirements thereby enhancing the option for photovoltaics. A key attribute of sustainability is energy/resource conservation over the life cycle of the building. The Modular Housing System's unique bolt and clamp connection allows disassembly with one hand tool and relocation and reconstruction in the same or entirely different configurations. This means that the life cycle of the building is extended indefinitely or that it offers many life cycles' worth of energy and resource conservation. The unique simplicity and flexibility of the Modular Housing System concept truly allows it to sit lightly on the land and adapt to the nature of its environment in an optimal example of sustainability.
