ARC102BConstruction Theory Green Sustainable Residential construction
Sustainable • Dictionary definition • capable of being maintained at a steady level without exhausting natural resources or causing severe ecological damage
Green / Sustainable construction • building new homes in a manner that conserves resources • a design that is less damaging to the area in which it is being placed • roads (asphalt) that allows water to pass through it
Green / Sustainable involves • land planning, site development • preserve the natural environment and minimize disturbance of the land • reduce erosion, minimize paved surfaces and runoff and protect vegetation, especially trees • water conservation indoors and outdoors
Green / Sustainable involves • energy efficiency in heating/cooling systems, appliances, lighting and the building envelope • selection of materials based on recyclability, durability and the amount of energy used to create the material • waste reduction, reuse and recycling during construction and throughout the life of the home
Renewable Energy • Definition: • any naturally occurring, theoretically inexhaustible source of energy • not derived from fossil or nuclear fuel • solar, wind, tidal, wave, hydroelectric power, biomass and geothermal
Types of renewable energy • Sun • passive use of solar energy involves directly capturing its warmth and light through building design • active use happens by using technology to transform the sun’s energy into electricity
Types of renewable energy • Wind • fastest-growing energy source • have been used for hundreds of years • turbines can be situated on land or off-shore
Types of renewable energy • Hydropower • the force of flowing water, or the movement of tides and waves, can be used to generate electricity • damming rivers
Types of renewable energy • Biological • agricultural residue • plant matter • agricultural crops, e.g. sugar cane, corn • paper mill residue • urban wood waste • forest residue • landfill methane, and • animal waste and sewage
Types of renewable energy • Geothermal • derived from heat that is stored deep in the earth's crust
