b. A method of framing structures that was used early in history that included adobe
construction integrated with stud wall construction.

Write your answer neatly print (so I can read it)
List five features that you might include in a wood frame structure to make it sustainable.
Consider the foundation, the site location and topography, wood framing techniques,
lumber vs engineered wood, insulation, roof types, etc. Briefly describe why each item
that you listed is sustainable. Note: this question includes information from previous
lectures as well as your own knowledge.
1. Wood framing techniques- Wood frame structures can be made more sustainable by using
members that are dimentioned to utilize its full length and breath. Thus, reducing wastage.
2. Engineered wood is prefabricated which makes it more durable and fire resistant
3. Modular forms bring down the cost and machine use makes the product more sustainable
4. In order to reduce the environmental footprint, recycled wood products can be put to use
5. shallow foundation will make it more cost effective and sustainable
