Cons: Keep in mind that these alternative construction technologies perform poorly in seismically active places, making them less attractive in earthquake-prone California. Furthermore, all of these building methods need professional personnel and are time and cost-intensive. Finally, many traditional materials such as wood and steel may be inconvenient for some builders to work with. Pros: By using alternative materials, innovative builders can create structures that are better insulated, require less maintenance, and last longer than traditional buildings. These benefits can help drive down the cost of living for people who live in green homes in California. There are several different types of building techniques used in green homes. Some examples include straw bale housing, earth sheltering, and cob. Each method has its advantages and disadvantages, so it's important to consider how you want your home to function before choosing a build technique. For example, if you want to reduce your energy bill but don't care about having a certain look for your house, then a simple design with flat roofs and open floor plans is all you need. You can find more information about each technique on their respective websites.
