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.

Penn State SALA Building - Recycled Copper Cladding

Copper used in green building materials and strategic building components contributes to high environmental and building performance in many areas, most of which qualify for credits towards LEED certification of a building. For example Pennsylvania State University's School of Architecture and Landscape Architecture (SALA) used over 80,000 lbs (35,000 kgs) of copper in its construction and it was the first building to achieve a gold LEED certification at no additional cost. Most noticeable is the pre-patinated, 95% recycled copper cladding used for the exterior walls as shown above. This green building project used copper extensively for copper's green properties: high recycled content; local or regional availability; durability; high rate of recyclability at end of building's useful life; low or non-existent maintenance costs for copper; workability of copper. To maximize these benefits, in addition to wall cladding, copper was used for all soffits, sun shading and even on ceilings of large atriums. Looking at long term cost factors also ensured copper's prominent role in this green building project. Copper's legendary durability is measured in generations rather than years or decades with little to no maintenance required throughout it's lifetime. Virtually 100% of the copper can be recycled upon eventual demolition or replacement of the building and recycled copper maintains 95% of the value for new mined copper. Copper also has the best heat and electrical conductive properties of any viable metal as well as superior resistance to corrosion. Copper's many attributes are reflected in copper's contribution to green building high performance with 13 possible LEED credits across 3 performance areas. Copper's aesthetic qualities also ensure green building architects achieve attractive, visually appealing green LEED designs without sacrificing any efficiency, performance or environmental objectives.

Green Home - Copper Building

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 whole field of green building is literally exploding and there is so much information already available out there on many of the aspects involved with green building. Today's blog is just an overview that defines what green building is and there will be a subsequent series of articles that will cover in more depth the many aspects involved. We will also closely examine and feature the role of copper in green building and green homes. Copper homes, copper building and copper architecture play an important part in virtually all green building designs, including some or all of the following: plumbing, wiring, solar panels, windmills, tankless water heaters, external wall siding, roofing, guttering, roof structures, flashing, chimneys, fascia, vents, duct work, healthier copper kitchen designs, even outside door and window cladding. Copper usage in fact can contribute upwards of 13 points in various areas towards LEED green building certification.
