Climate ChangeU.S. Energy Consumption by Sector

Building:48%, Transportation: 27%, Industrial: 25%


The Built EnvironmentIn the United States, Buildings: 1. Consume 65% of electricity 2. Create 30% of total greenhouse gas emissions 3. Create 136 million tons of C&D waste each year 3. Create 136 million tons of C&D waste each year 4. Consume 10% of potable water 5. Use 40% of raw material globally


Environmental Impacts of Traditional Buildings

83 million buildings in the US as of 2013Continue to be used for many yearsLots of land, energy, water, material….


Lots of land, energy, water, material….Lots GHG & harmful air pollutant >40% world energy and 25% of CO2 75% account for electricity (EPA 2008) Energy 2025 19%↑. 2X Germany, 3X Japan

Quality of life 15% of homeowners in the U.S. may be allergic to

elements in their own homes 40% of children born today will develop some

form of respiratory diseaseform of respiratory diseaseOf all the chemicals that the EPA monitors, only 2

(ozone & sluphur dioxide ) are more prevalent outdoors than indoors


什麼是 CALGreen CALGreen is California Green Building Standards Code The purpose of CALGreen is to improve public health, safety

and general welfare by enhancing the design and construction of buildings through the use of building concepts having a reduced negative impact or positive environmental impact and encouraging sustainable construction practices in the following encouraging sustainable construction practices in the following categories: Planning and design Energy efficiencyWater efficiency and conservationMaterial conservation and resource efficiency Environmental quality


什麼是 Title 24?Local energy ordinancesThermal massCool roof, window & skylightRadiant barrier & Vapor barrierRadiant barrier & Vapor barrier Insulation and lightingWater heater & HVACMust be 15% beyond original T24.
