Introduction to Green Buildings & LEED:  Introduction to Green Buildings & LEED Defining Sustainability:  Defining Sustainability United Nations World Commission on Environment and Development “Development that meets the needs of present generations without compromising the ability of future generations to meet their own needs.” Defining Green Buildings:  Defining Green Buildings Design and construction practices that significantly reduce, or eliminate the negative impact of buildings on the environment and its occupants with regard to site planning; safeguarding water use and water use efficiency; promoting energy efficiency and renewable energy; conserving materials and resources; and promoting indoor environmental quality.” (US Green Building Council) Construction Impacts:  Construction Impacts 76 million residential buildings in US 5 million commercial buildings in US consume 40 % or raw materials 32% total energy produced 17% fresh water 25% global wood harvest 5 billion gals water/day just for toilets generates 25-40% of municipal solid waste from C&D 50% of US CFC production 30% of US CO2 production Building Operations Impacts:  Building Operations Impacts 49% of Sulfur Dioxide emissions 25% nitrous oxide emissions 10% of all particulate matter 1/3 of all energy consumption in US 2/3 of all electricity consumption in US disturbs natural habitats contaminates air, soil, and water depletes non-renewable resources ½ of greenhouse gases 35% of carbon dioxide emissions community issues occupant issues sources: “The Architecture of Sustainability, 2002”, World Watch Institute, USGBC Key Issues and Benefits:  Key Issues and Benefits Institution Building Commissioning Air Quality Occupants productivity and well being Energy Conservation Water Conservation Storm Water Management Waste Management Local & State Standards & Programs Green ethics / commitment Research and Grant opportunities Being a leader (as it should) Responsibility to show importance Competitive advantage (ie – recruiting) Institutional community demand Great public relations Overall Financial Benefits:  Overall Financial Benefits Energy Water Wastewater Reduced Waste Improved Indoor Environmental Quality Greater Employee Comfort/Productivity Reduced Employee Health Costs Lower Operation and Maintenance Costs Competitive First Costs Through integrated design & synergies Increased Value & ROI Marketing Advantage Reduced Liability Improve Risk Management Insurance costs Overall Financial Benefits:  Overall Financial Benefits Financial Benefits of a Green Building equate to $50-$70 SF over lifetime Over 10X return on any premium cost associated with building it over lifetime Source: USGBC Air Quality:  Air Quality Indoor Air Quality (IAQ) – effect the contents of the inside air has on a structure and its occupants People spend 90% of their time indoors Indoor air has 10-100X higher pollutants than outdoor air USEPA “Indoor Air Quality” Jan, 6 2003 Energy Conservation :  Energy Conservation US uses 25% of world energy but only has 5% of population & 95% of our energy is from fossil fuels (US Energy Information Administration) Higher Education - $2 Billion/year on energy (American School & University) Most can reduce by up to 30% - savings can be used on: New faculty Upgrades/renovations for more savings New programs Water Conservation:  Water Conservation USA uses 340 billion gallons of fresh water per day Nearly 65% is discharged into waterways Energy Policy Act of 1992 Facilities can easily reduce use by 20-30% with little cost and effort Water & Sewer Bills Connection Fees & Tax Base Occupants Well Being and Productivity:  Occupants Well Being and Productivity Relationship exists between worker comfort/productivity and building design/operation Hidden sick days – higher absenteeism, respiratory ailments, allergies, asthma = lower productivity, higher insurance and medical costs A 1% increase in productivity (about 5 minutes per day) equals $600-700 per employee per year - a ^1.5% equals about $1,000/yr (Katz 2003 study) Mythology About First Costs :  Mythology About First Costs Common Perception when we started was +20-30% Past & Current Trend Recent Studies Average Premium <2% or $3-$5 SF Most of cost associated with increased architectural and engineering design, time, modeling and integration time Earlier you integrate the lower the cost Mythology About First Costs:  Mythology About First Costs Source: USGBC, Capital E Analysis Mythology About First Costs:  Mythology About First Costs Another recent study has shown the following average increase in project construction costs, on a percentage basis for LEED certification. Certified 0 – 2.5% Silver 0 – 3.3% Gold 0.3 – 5.0% Platinum 4.5 – 8.5% Start Early – Save Costs Source: Sasaki Associates 2004 Mythology About First Costs:  Mythology About First Costs Building green can be done for no additional cost Initial premium costs are entirely up to you and project specific LEED buildings average only a 2-3% increase in costs, but can be done for the same budget as traditional buildings with planning Savings from green building’s more than return any premium you may choose to put into it Design Fees will be higher but construction costs may be reduced Set Budget first then work fees within framework General Mythologies:  General Mythologies Appearance of Green Buildings You design it to look how you want. It can easily match traditional campus design or not. Carpet, furniture and windows do not have to look different. They can look like traditional ones only they perform better and are healthier. Does not need to be high tech to be green. Time Green Buildings take the same amount of time to construct as regular buildings. More time may be required in the Design phase though. Costs Green Buildings do not have to cost more. With planning they can be built at the same price or less. Design fees may be higher in the beginning of the project but the extra design work will lower the actual construction costs. In the end the building costs the same and fits in the traditional budget. Normal: 2 + 2 = 4 Green: 3 + 1 = 4 Long term maintenance and operations costs can be reduced by 20 – 50% with good planning.
