LEED
LEED is the 21st century brand new comer. I started seeing more and more LEED certified courses, construction after year 2000. The problems we faced and learned from LEED projects is that budget allocation (per initial materials/ equipment estimates) especially in large federal/ state government/county/metropolitan projects is normally off, in turn the implementation of work becomes chaos, generating lawsuits sometimes, even 30-40 years experienced skilled workers have a very hard time to build and install in sync with the project criteria. Just like you change the formula you have been using for your whole life. A lot of times you have problems getting the right stuff with the right price to comply with the project design and also cost control wise I see it is disasterous. the intention is very good but implementing true and ideal LEED installation and building is questionable still to this day for the private enterprises and their LEED projects
LEED Is a green building certification that is a mark of quality and achievement in sustainability
LEED Is a green building certification that is a mark of quality and achievement in sustainability
LEED, or leadership in Energy and Environmental Design, is the
most widely used green building rating system in the world. Available for
virtually all building, community and home project types, LEED provides a
framework to create healthy, highly efficient and cost saving green buildings.
LEED certification is a globally recognized symbol of sustainability
achievement
LEED, construction that deploys materials with no or reduced or
limited VOCs (volatile organic compounds) content. In short LEED construction
is taking out VOCs from construction materials
VOCs (volatile organic compounds) are organic toxic chemicals
that are emitted from a variety of household products and materials. Every
thing from house paint to that new couch you just unwrapped will contain levels
of these chemicals
VOC emissions can be especially bad for people with compromised
immune systems, as well as children and elderly
VOC means any compound of carbon, excluding carbon monoxide,
carbon dioxide, carbonic acid, metallic carbides or carbonates, and ammonium
carbonate, which participates in atmospheric photochemical reactions – VOC
definition per 40 CFR part 51.100 (S) (as of October 30, 2014)
“ Eyes, noses and throat irritation, headaches, loss of
coordination and nausea. Damage to liver, kidney and central nervous system.
Some organic can cause cancer in animals, some are suspected or known to cause
cancer in humans”
VOC also means that are organic materials that have a high vapor
pressure at ordinary room temperature. They include both human made and
naturally occurring chemical compounds
Examples of VOCs are gasoline, benzene, formaldehyde, solvents
such as toluene and xylene, styrene, and per chloroethylene (or
tetrachloroethylene) the main solvent used in dry cleaning
How can you reduce your VOC impact?
Ventilation and climate control:
Increasing the amount of fresh air in your home. Will help
reduce the concentration of VOCs indoors. Increase the ventilation by opening
doors and windows. Use fans to maximize air brought in from the outside. Keep
both temperature and relative humidity (RH) as low as possible or comfortable
VOCs are carbon containing compounds that evaporates easily from
water to air at normal temperatures (This is why distinctive odor of gasoline
and many solvents can easily be detected
VOC are primary precursors to the formation of ground level
ozone and particulate matter, which are the main ingredients of smog. Smog is
known to have adverse effects on human health and environment (The Environment
Canada Air site provides more info on smog)
Other sources of VOCs include the burning of gas, wood and
kerosene, as well as tobacco products. VOC can also come from personal care
products such as perfume, and hair spray, cleaning agents, dry cleaning fluid,
paints, lacquers, and from copying and printing machines
