LEED or Leadership in Energy and Environment Design is a third party certification and building rating program for building performance across several key areas. LEED attempts to measure a building's performance and sustainability across such areas as: optimizing energy efficiency as well as use of renewable energy; efficient and sustainable use of building materials and resources, including reuse, renewability, recycling and durability; innovation of design, incorporation of high recycled and regional content; water conservation; ensuring infrastructure and limiting neighborhood and environmental site impact; indoor air and environmental quality, including occupant comfort; reduction in CO2 emissions; efficient operation with low or reduced maintenance and energy costs. Developed by the U.S. Green Building Council (USGBC), LEED is a voluntary certification which strives to verify and promote sustainable high performance buildings or communities with less environmental impact, improved livability and long term savings. While LEED is still evolving, incomplete and not nearly perfect, building rating systems, certification and verification are raising our awareness and expectations for building performance and helping shift the construction market and demand toward healthy sustainable building, our long-term well-being and environmental responsibility.

Green, green home, green building, going green, sustainability and LEED are all catch phrases that seem to be catching steam and quickly building momentum these days. What does go green and green building specifically mean? Green building is the philosophy, design and implementation of the most efficient use of resources, that are both environmentally responsible and positively affect our health throughout the building's entire life cycle. The building's life cycle starts with siting, includes design, construction, operation, maintenance, renovation and then finally demolition. The total long term environmental cost of all building components is calculated and factors into green building design. Green building extends traditional building's short term concerns of economy, utility, durability and comfort with long term goals of sustainability, high performance, human health and environmental impact. The environment is impacted by the production and consumption of materials, natural resources, energy, water and land. Our environment is adversely altered by the building's inhabitants generation of waste products, water pollution, air pollution, heat and noise. Ultimate effects may include harm to human health, degradation of the environment including the atmosphere and loss of natural resources. Green building's goal is to reduce or eliminate any adverse health and environmental impact for every kind of building including residential, public, governmental, religious and commercial.

The need to prevent the spread of germs has always been a major concern. Research indicates that a copper surface is more effective at preventing the spread of germs than stainless steel. Copper has a 2000 year history of antimicrobial applications in a multitude of cultures. More recent research has sought to determine uncoated copper's effectiveness in stemming the proliferation of infectious disease. At the University of Southampton in the U.K. research studies have shown that many common disease causing microbes such as  E. coli, Aspergillus niger (black mold) and Influenza A, die within hours on copper surfaces. The Influenza A family of viruses includes the problematic Avian flu and swine flu strains and copper can help contain a flu. Even deadly antibiotic resistant bacteria associated with infections such as MRSA (Methicillin Resistant Staphylococcus Aureus) die within 1.5 hours on pure copper. On stainless steel and plastics, typically used for food-processing hardware, pathogens survived unabated for days, sometimes more than 30 days. There is enough solid evidence to put man’s oldest metal to work throughout the world to help protect us from infectious disease. Tested copper alloys, such as brass or bronze also offer increased protection over non-copper containing materials such as stainless steel, painted surfaces, wood and plastics, although not nearly as effective as pure copper surfaces.

Some fairly common and obvious uses in the home for elegant yet functional copper home decor include copper kitchen sinks, bathroom copper sinks, copper bar sinks, food prep sinks, copper basin, copper vanity sink, copper door knobs, copper handles, copper range hoods, copper planters, copper pot racks, copper bowls, copper sheets or copper tiles for making copper countertops and copper sink backsplashes, copper tabletops, copper chair arms, copper wall plates and switches, copper light canopies, copper ceiling fans, copper vents, copper louvers, copper cookware, etc. There are germ killing copper facades available for refrigerators, dishwashers, freezers, ice-makers, ovens and ranges. There are copper-plated kitchen appliances, copper vases, copper sculpture, copper accent pieces, copper planters, even copper flowers. Copper bathroom fixtures and copper kitchen appointments may be the most obvious places to most benefit from and utilize copper's antimicrobial power, yet manufacturers are now focusing in on all home furnishings and furniture as well as laptop, remote control and cell phone cases. The ceiling for new copper surfaced products is sky high, especially considering copper's aesthetic qualities, durability, long lifespan and green copper work as eco-friendly too.
