Design Sustainable Buildings Assessment 1：Alternative Wall Construction

The frame is completed, the waterproof board is finished, and a waterproof coating is used.

From the last step we continue on the frame of our Straw Bale wall. Before we place the batten on the frame we measure the distance of our window and label the point by pen on the batten then placing the other timber on the frame so that the measurement don't get error as possible as we can, after that we place right angle plate between two batten to hold them together by bolts so they are tight and stable. Picture below is the frame that we finally get by the method previously.  Using the same method another side of the wall frame is done, after the window frame is placed we connect the two column with timber that we cut out previously with the width of 300mm as our window size are 300x300mm.

 FIRST STEP WE USE THE PLATES AND BOLTS TO FIXED THE MGP10 FOR THE TRUSS.

STRAW BALE WALLS' ADVANTAGES AND DISADVANTAGE Advantages of straw bale construction 1. Straw bales are made from a waste product. Once the edible part of the grain has been harvested (such as wheat or rice), the stalks often become a disposal problem for farmers. By bailing the straw, a new life is given to the material. The farmer makes some money by selling the bales and the homebuilder gains an excellent insulation and building material. 2. Homes insulated with straw bale can have insulation values of R-30 to R-35 or more. The thicker the bale, the better the R-value. 3. Straw bale walls are at least eighteen inches thick. This adds aesthetic value to the home as thick wall are expensive to achieve with conventional construction. The thickness of the wall helps to reflect sunlight throughout the room. 4. Due to the thickness of straw bale walls, every window can have a window seat or shelf. This becomes both an aesthetic and practical design element. 5. The con
