sustainability: day 2

sustainability:
sustainable design:
design focusing on products and processes that protect the environment while conserving energy for future generations

popular: last 10 years; 1960's design started to change in terms of making solar homes, passive solar structure: orient house/ structure to gather natural light (heat for winter, trees create shade)

global energy usage: increases 70% between 2003-2030
major source of energy world wide: natural gas, oil, coal,
-bi-products: carbon footprint makes global warming
nuclear:
renewable resources: water, sunlight,

key terms of green design:

-green planet: recognize green product (what products produce concerns)
-energy star: energy efficient products, environmentally friendly when being disposed: windows, building products, appliances

US green building council: developed the leadership in energy and environmental design (LEAD design)

LIGHTING:
made ID's more important: control material specification;
lighting: compact florescent lighting, life cycle is more extensive (lower electric bill), doesn't create heat
florescent better than incandescent bulb

sustainability will work when it becomes more affordable
40% of the energy used in a building is lighting
have the ability to harvest indirect natural daylight (direct sunlight can be harmful)
-contain toxics and mercury

LED lights: light emitting diode
-produce colors; just now getting the white light as ambient general lighting
-better than florescent


CONTROLS: switch
daylight switching plans: lights would switch off when sunlight is coming in

FLOORING:
wood: can be reused, specify from the region- trucking cost from far away
linoleum: turpentine; more efficient

multi-functional spaces are the most efficient, as they are being used for many different purposes.
