Carpet padding made from recycled fibers reduces the need for petrochemicals and outgasses less than a typical foam pad. Duct systems can be leaky in many areas and most are. This is bad for energy bills and worse for health and safety. A leaky duct system can create pressure differences in a home's heating system which can draw in contaminants like dust from the attic, soil gasses, or flue gasses. A well designed yard needs less water and maintenance, and saves money.
Native vegetation competes well with weeds and other pests.
As a result, less fertilizer and pest control is required. Using native, indigenous plants will reduce the need for water. Since native plants may be already accustomed to the climate, they are drought resistant and withstand greater climate variations than non-native plants. Landscape designs should avoid incorporating allergy-causing plantings and those requiring chemical treatment adjacent to air intakes, entries, or operable windows. Landscape designs can help reduce energy bills.
