There are many designs, shapes, and textures to homes today. Some are large, and some are. Some are tall, and some are wide. While I feel only a few restrictions should be placed on homes in comparison today in regards to designs, I feel that the house should be dramatically changed from what they are today.
The reason is the home is the cause of 45% of the greenhouse gases. Imagine if every home was to these standards, we could cut our pollution by almost half. These proposals of requirements are based on technology of today, and while a little more expensive (expect +25%), this would be a dramatic savings to the environment (small carbon footprint), nature (small reality footprint), and the pocket (smaller impact on your finances). However, considering the dramatic changes, these would probably be best for new homes.
