Potable water also known, as drinking water, is water that is safe enough to be consumed by people or be used with a low risk of any instantaneous or long term harm. Originally potable water was made out of lead piping, however, after the known dangerous affects of lead poisoning the piping for potable water changed to copper. Copper was known as the better and safer alternative that is used in potable water today. Typical uses of potable water include toilet flushing, washing and landscape irrigation.   

Waste piping is the system that is responsible for sewage and greywater removal from a building or home. Also know as drain-waste-vent (or DWV), waste piping also regulates the air pressure on the piping system, giving a smoother flow. The waste that is produced comes from toilets, skinks and showers and is disposed through waste piping. Any fixture that products any sewage or greywater must be connected to waste lines, which take the waste to a soil vent pipe or soil stack. Waste in then removed from the building through the building drain and moved to a sewage line, which ends up in a public sewer or septic system.   

Natural gas piping is a system that is responsible for the release of gas in a building. The most common type or natural gas that is used in natural gas piping is methane. The use of natural gas piping in buildings includes heating, lighting, the distribution of gas (at a gas station), and if there is a kitchen (such as in a restaurant or home) the release of a flame. Plastic piping that is made out of polyethylene is most frequently used natural gas distribution because it is known to be the most efficient piping to be used for gas. Natural gas runs run in a building or a home through what is called a service line. Once the gas is passes through the pipes it travels to the appliances through which the piping is installed. When it comes to the distribution of natural gas there are sophisticated computer systems that are use to assess the delivery of the gas and to make sure that the user will receive a sufficient amount of gas at or above the minimum pressure that is required by appliances that the gas is used for.

In 1978 California first initiated Title 24, which is also known as The Energy Efficiency Standards for Residential and Nonresidential Buildings. This was created by the California Building Standards Commission to reduce the consumption of energy in the state of California. Since then, Title 24 has helped Californians save more than $56 billion in electricity and natural gas costs, as well was reduced pollution and other detrimental impacts from the utilization of fossil fuels. Title 24 has truly become a cost-effective mandate by the state of California. When it comes to new energy efficiency methods and technologies, Title 24 keeps up to date in order to keep to the energy efficient standards as current as possible.
