Energy efficiency improvements such as high levels of insulation, efficient HVAC systems, high-performance windows and energy-efficient appliances and lighting. Water conservation measures such as water-efficient appliances and fixtures, filtration systems, and drought resistant or low-maintenance landscaping. Resource conservation using materials and techniques such as engineered wood and wood alternatives, recycled building materials, sustainably harvested lumber, and more durable products. Indoor environmental quality considerations such as effective HVAC equipment, formaldehyde-free finishes, low-allergen materials, and products with minimum off-gassing or low volatile organic compounds (VOCs). Site design planning such as minimizing disruption and preserving

UPFRONT COSTS vs. LONG TERM OPERATIONS & COSTS

Consider Life-cycle costs:

A 2% increase in upfront costs due to the use of green building products would result in life cycle costs of 20% This is 10 times the original investment
