2 Green building is the practice of…. 1) increasing the efficiency with which structures and their sites use energy, water, and materials.(2) reducing the impact on human health and the environment through better siting, design, construction, operation, maintenance, and waste removal through the complete building life cycle.
3 Financial and Environmental Incentives into account for any building project.It is not more expensive to build “green” if you take into account the complete life cycle of the structure. The decreased operating costs, health benefits, comfort levels, environmental benefits and future value should be taken into account for any building project. be taken
4 Financial and Environmental Incentives • high benefit lighting techniques• less toxic materials• energy efficient air handling systems• access to natural day lighting• superior indoor air quality• individual control of heat, light, and ventilation• landscapes designed to conserve rainwater andnatural sunlight
5 Product innovations have also influenced “green” building programs Product innovations have also influenced “green” building programs. In addition, many environmental laws have been implemented in the last 10 years, forcing builders and renovators to step up to the plate. Here are just a few results one may expect from High Performance Commercial and Residential Buildings….
6 • reduction in liability insurance • reduction in workers compensation cases• increased market value up to 100%• decreased energy costs up to 90%• decreased O and M costs up to 73%• overall paybacks of 2-4years• higher tenancy ratesand demand
7 The Structured Insulated Panel is known for its durability in high wind areas and hurricane and tornado prone regions.
8 Some examples of natural materials used in sustainable building practices around the world, depending on climate, are relatively new to the vocabulary. Examples are:*Cordwood*Strawbale*Bamboo*Earthship*Cob- Rammed Earth
9 UNDERSTANDING HIGH EFFICIENCY WATER HEATER TECHNOLOGIES Storage (Tank) Water Heaters*Water is kept hot and ready for use at all times in insulated storage tanks with capacities ranging from 20 to 80 gallons. Many fuel options are available, including electricity, natural gas, oil, and propane. One drawback of these units is the energy used (wasted) to keep the water hot at all times, otherwise known as “standby losses.”Demand (Tankless) Water Heaters*Water circulated through a large coil is heated only on demand using gas or electricity; there is no storage tank continuously maintaining hot water. A possible concern with this technology is the limitation on the number of fixtures that can simultaneously use hot water. However, there is an endless supply of hot water and standby losses are eliminated.
10 UNDERSTANDING HIGH EFFICIENCY WATER HEATER TECHNOLOGIES Heat Pump Water HeatersHeat pumps transfer energy from the surrounding air to water in a storage tank. These water heaters are much more efficient than electric resistance water heaters and most effective in warm climates with long cooling seasons.Solar Water HeatingWhile the initial purchase price of solar water heaters is very high compared to standard models, they can be cost effective. That is because the sun’s energy is harnessed to reduce operating costs up to 90 percent. Solar water heatingsystems require a conventional water heater as a backup water heating source to ensurehot water is available when solar energy is not.
11 In green building, the materials used must adhere to strict guidelines In green building, the materials used must adhere to strict guidelines. Materials used should be without toxins, like formaldehyde commonly found in paints and adhesives. The more non-toxic materials used in the building process, the more points are achieved in the rating process. Some of the materials and structures used in green building include:
12 Green Building Materials and Structures • Shaved trees for building materials, instead of whole trees. This way trees are not killed for building• Carpeting made from recycled materials such as tires• Tile made from recycled glass• Organic cotton fabrics for upholstery and accessories• Sidewalks made from recycled tires (These are designed to absorb rainwater, recycle it through a pump, and use it to flush toilets, water your yard, etc.)• Walls made from the SIPS we mentioned earier concrete forms and structured foam products to withstand high winds.• Adhesives, insulation, grout, and finishes with low volatile organic compounds (VOCs) or no VOCs.• Water furnaces, which utilize rainwater with little to no need for fossil fuels.• Sun Pipe light tubes for gathering sunlight.• Hybrid lighting systems• Tankless water heaters
13 *You can see these all relate to not only lower utility bills but better IOQ ( Indoor Air Quality ) for the occupants.You will begin to see newly designed more efficient water heaters, dishwashers, washer and dryer appliances taking up less space, having larger capacity, yet conserving energy and water, automatically adjusting to hot water needs, and using less power to run.*Solar storage tanks are here to release this stored energy for uses in the home.*Refrigerators using sensors monitoring temperature and defrost cycles. These same systems will run just as well from electricity supplied by renewable energy resources such as wind and solar converters.
14 *Units offering sealed combustion, direct venting, load size sensors, more efficient heat exchangers and even IPI-Intermittent Pilot Systems saving a system from running when not needed are becoming popular. These will operate similarly to occupancy controls for saving energy for electric lighting already in use.*Tankless water heaters are wonderful for the concept of using energy "on demand."*Look for geo-thermal systems that use the constant temperature from the ground for plumbing and HVAC needs of a built structure. A well drilling is necessary but when all is said and done, using our land for indoor temperature makes sense.
15 Consumer Energy Study According to a www.energypulse.org 86% of Americans would choose one home over another based on energy efficiency.78% of Americans who just bought property say nobody talked to them about energy efficiency.62% of people want energy efficient dwellings. 63% say energy prices have increased enough to make them consider changing their consumption habits.
16 Cisterns*A cistern may become a more popular option. The water is filtered and stored for future use.*Their effectiveness will be based on consumers needs- You would need 45 rain barrels to equal one 2500 gallon cistern. Get to know the contractors in your area. Add these types of systems to your ideas for the new era of "green."
17 Environmental Factors Consider these facts:25% of virgin wood is used for construction, adding to:• deforestation• flooding• biological and cultural diversity losses.Past building construction design accounts for 40% of total energy use, adding to:• local air pollution• acid rain• damming of rivers• nuclear waste• risk of global warming.
18 LEED Commercial Certification *USGBC established a point-scale rating system, detailing the standards to be followed to achieve various levels of certification. Under the LEED® 2.0 system, a commercial project is awarded up to 69 points in the categories of:1 – Sustainable Design2 – Water Efficiency3 – Energy and Atmosphere4 – Materials and Resources5 – Indoor Air Quality6 – Innovation.LEED Point System for Commercial Certification: Certified – points Silver – points Gold – pointsPlatinum – points and to qualify for LEED 2009, the points will go to 100.
19 LEED Home Certification LEED for HOMES® promotes the transformation of the building industry towards sustainability in the residential sector, utilizing a 100¬point scale.LEED Point System for Home Certification:Certified – 45 – 54Silver – 60 – 74Gold – 75 – 89Platinum – 90 – 136Some of the criteria they evaluate for these ratings are within these eight resource categories:1 – Innovation and design2 – Location3 – Sustainable sites4 – Water Efficiency5 – Energy and Atmosphere6 – Materials and Resources7 – Indoor Air Quality8 – Awareness and Education
20 According to the US Green Building Council: • Health is better in green built homes andgreen commercial structures• Less toxins in building materials combined with higher SEER (Seasonal Energy Efficient Rating) air handling systems produce better indoor air quality• Student test scores are 20% higher in green schools and teachers are more engaged in their work• In green hospitals, nurses make fewer mistakes and patients are released two days earlier• In green office buildings, productivity is higher – absenteeism is lower• In green shopping malls (using day lighting and fewer toxic finishes), retail sales are higher.
21 The average family spends up to $2,400 a year on energy bills *The average family spends up to $2,400 a year on energy bills. When you reduce the amount of energy used in your home, you save money on energy bills.*In addition, using less energy reduces the greenhouse gas emissions. Fossil fuels are currently used for heating and for generating electricity, in addition fueling our automobiles. So using less energy in our homes can dramatically reduce our environmental footprint in terms of global warming, while protecting our environment for future generations.
22 Home ImprovementsTax credits are available for many types of changes in lifestyle. Home improvements include adding insulation, replacing windows and installing certain high efficiency heating and cooling equipment.*installing residential solar photovoltaic and hot water heating systems*constructing or maintaining energy efficient commercial buildings*construction of energy efficient new homes *improvements to existing homes, including installation of high-efficiencyair conditioners and other energy saving equipment*installation of residential fuel cell systems*installation of fuel cells and micro turbines (for a business)
23 Tips to Make Your Life More Eco-friendly -Carpool, walk, ride a bike, use mass transit, or work at home:If every commuter did this one day each week, we’d save 5.85 billion gallons of gas and avoid creating 143 billion tons of CO2 every year.-Knowing that heating/cooling accounts for about 45% of a home’s total energy use, we need to seal doors and windows and insulate well. The average home causes more pollution than our cars because of the fossil fuels burned to supply the power we need.-Unplug everything when not in use: Standby power can account for 9-10% of household energy; A television uses 25% of its energy when turned off.
24 Tips to Make Your Life More Eco-friendly cont. -Take shorter showers: Aim for no more than five minutes. Also, using low-flow shower heads will prevent 472,630 lbs. of CO2 from entering the atmosphere nationwide.-Lighting accounts for 20% of all electricity consumed in the U.S. Use energy efficient light bulbs and fixtures, and turn off lights whenever possible.-Stop junk mail. The production of junk mail (logging, paper production, ink manufacturing, printing, shipping, etc.) consumes as much energy as 2.8 million cars annually. That represents 200 million trees killed just to create the paper — equivalent to cutting down all the trees in Rocky Mt. National Park three times.
25 Obtaining a Larger Home Loan A HERS Report includes:• Overall Rating Score of the house in its current condition• Recommended energy upgrades.• Estimating the cost, annual savings, and useful life of upgrades.• Improved Rating Score after the installation of recommended upgrades.• Estimate total energy cost for home before and after energy upgrades.
26 *The U.S. Department of Energy recommends Home Energy Ratings contain a number score from 1 to 100. Higher scores indicate higher energy efficiency.*Most lenders should have a good understanding of EEMs (Energy Efficient Mortgages), to help consumers upgrade their properties.*If a client normally qualifies for a $260,000 home, they’ll actually qualify for $280,000 with an EEM. How does this work? When a lender factors in the rating for energy upgrades (which will provide a savings on utility bill), along with the many tax advantages offered by the government loan, this creates a positive appraisal evaluation; hence, the consumer can qualify for a larger loan.*In some states, permitting moves quicker if you’re building or renovating using green.Certain lenders and products also offer higher ratios to compensate for the savings produced by green properties.
