Once what was invisible and irrelevant to the naked eye can now be documented, quantified, published and benched mark for competitive advantage market resale for your largest investment. Your green communities certified home. Missing from the marketplace for more than decade sustainable homeowners can now find and locate a knowledgeable green appraiser having access to universal green underwriting tools are now able to quantify all the individual specific green appraisal features constructed into your green communities home. In September 2011 The appraisal institute introduced form number 802.03

Residential Green Energy Addendum is a specific addendum to be used in conjunction with popular Fannie Mae/Freddie mac form 1004 called the green energy efficient addendum. Both GSE Fannie Mae and Freddie Mac underwriting guidelines require all lenders to choose knowledgeable appraisers who have the essential knowledge to perform an appraisal for a specific geographic region or property type. The green addendum is specifically designed for knowledgeable green appraisers who are familiar with and completed specialized education for valuing residential and commercial green buildings, residential green valuation tools, residential and commercial solar photo voltaic valuations, and the ability to comprehend and value all types of net zero real estate.

Over the last 30 years energy efficient green features have been largely ignored or not even considered when appraising a home or commercial property type. Even today some lenders have told appraisers to value homes as conventionally constructed homes. The green addendum provides documented third party green appraisal verification. Specifically acknowledging intrinsic value of specific independent identified energy efficient items such as, but not limited to: A recognized green certification, all types of insulation, low E windows, CFL’s, tank less hot water tank, energy star appliances, solar panels, geothermal, walk-score, TOD, proximity to public transportation, Home energy score(HES), HERS ratings, A complete menu of green options available for the trained certified green appraiser to customize and add numerical score to your individual green appraisal of your green communities home!



Traditional appraisers are not familiar with green building or net zero real estate evolving green features and have previously failed to properly recognize and document these energy savings features in the green addendum. Completely overlooking the increased monetary value of energy and water efficient features which lowers the green properties annual operating costs. This has resulted in a lower appraisal valuation of green properties. Atlanta, and  Seattle, have the highest water rates in the country. Forty percent of Philadelphia households have had their water shut off since 2014 for non payment. Detroit has shut off water to 50k households. Water is now a scarce and valuable commodity. Water efficiency is now considered important by over 70% of  green home owners.

Therefore it is important to  select a qualified green appraiser that has the prior course completion education, and knowledgeable on going green metrics to properly appraise residential and commercial green buildings, including residential and commercial valuation of solar systems. Each appraisers knowledge and experience is unique. The Uniform Standards of Professional Appraisal Practice (USPAP) requires all appraisers to be competent to perform the current assignment. Acquire the necessary competency to perform the scope of work. This includes through knowledge of all green building techniques. Otherwise withdrawn from the assignment. The homeowner should ask questions to the appraiser to verify they are qualified or be replaced by a green appraiser. This is an important distinction that is commonly overlooked which could lead to a valuation dispute and thereby effect the green mortgage application.

This scenario of events has confused the public, to become misinformed, that certified green homes cost more to build and deliver the same value as conventional homes. Which leads to public confusion as what constitutes certified green building and leads to false green washing claims. There are numerous green building applications, The most common green building science principles incorporated into green appraisals focus on site location, water efficiency, energy sources and efficiency, green building materials used, operations and maintenance costs and Indoor air quality (IAQ) which will become more prominent in the near future.



The homeowner can be a valuable assistant to the green appraiser, providing specific relevant third party documentation in preparation for the green appraisal. Such documentation should include: energy star, or other national recognized green certifications, numerical HERS rating scoreHES, all types of green renovations/ specific energy upgrades, documentation such as: added insulation, geothermal information, solar panels, and all types of water conservation fixtures/devices which are now becoming a relevant addition to the green appraisal. All of these verifying documents need to be  included in the green mortgage underwriting documentation package. Department of Energy (DOE), Berkley lab and Sun shot  performed a multi state study of homes with photovoltaic solar panels installed. The  added value of solar panels is becoming increasingly important with home buyers now paying a green premium for these homes across the nation. The added green appraisal value is $4.00 watt or $15,000 for an average size system of 3.6KW solar system. The market depreciates the value of the PV system in the first 10 years exceeding the rate of straight line depreciation over the use full life of the system. Net cost estimates may now be the best analysis for market premiums. Which are based on government and utility incentives. In the fourth quarter of 2016 the solar panel market has shifted from third party leasing towards customer ownership.

Leasing has fallen to forty seven percent of all new installed residential solar panels. Solar City which dominates the residential solar panel market with a 25% market share. Saw a shift in consumer ownership to 28% of all solar panel instillation’s. Third party solar panel leasing provided the initial temporary financing mechanism to offer solar panel instillation’s. Green appraisers can assemble all of this green underwriting documentation which can be used in conjunction with the green appraisal energy addendum form. Additional documentation can include the PV values spreadsheet will provide consistent green appraisals for green communities homes that have photo voltaic instillation. (solar panels) and wind turbines! Documenting these green features can  now monetized and add additional value to your green appraisal!

As solar photo voltaic systems are now becoming an increasing popular green feature in green certified homes. Green appraisers have three different green appraisal methods to document the added value of solar panels. The first green appraisal method is using paired sales. Finding a comparable photo voltaic system on a similar property. The second method is the cost approach. Replacement cost of the entire solar system minus depreciation costs. The third method is estimating the value of the energy savings from the solar system. This can be accomplished by using the  PV values  excel spreadsheet for green appraisers nationwide to enter the zip code of the individual green communities home, solar system size in number of watts, the de-rate factor which takes into account the shading, tracking, tilt, azimuth along with several other factors, the spread sheet returns the value of the PV system located anywhere in the United States. It is interesting to note the rapidly fallen value of producing a solar watt has fallen from $4.00 a watt to soon under .50 cents a watt over the last several years!

As the cost per watt continues to fall, The efficiency of solar panels continue to rise! Today’s silicon based solar panel efficiency is between 16 to 18 percent. Solar City is currently developing and manufacturing a solar panel at over 22% efficiency. Purdue university and NREL have developed a new material  called perovskites which is thinner than silicon cells, more flexible, inexpensive and has the ability to double solar panel efficiency!

The PV value solar appraisal was designed by the Sandra National Laboratory to document and standardized green appraisals nationwide. This nascent green underwriting tool can be used by knowledgeable green appraisers, green brokers, green underwriters, green mortgages and  green securities, to provide accurate value for bench marking PV solar systems and wind turbines. Additionally a sustainable home-owner can now estimate the remaining present value, quantify the PV system and is able to place a monetary value of an energy efficient feature (solar panels, wind turbines) to a perspective sustainable home-owner purchaser.



Currently Solar city can now sell energy to homeowners in 14 states at a rate lower than the local utility company. As photo voltaic technology rapidly moves forward, the current common practice of simply installing an unsightly solar panel on top of a conventional “dumb” roof will become obsolete! The future will now include aesthetic solar shingles that look like conventional shingles, will include a mini glass quartz solar panel installed seamlessly onto a roof. The solar shingles will come in four designs. Tuscan glass tile, slate glass tile, textured glass tile, and smooth glass tile. Each designed to match the aesthetic look and texture of the exterior of the green certified home. Additionally all the solar shingles will have a 30 year life span and will be connected to in home battery storage systems.



As these two new technologies are implemented by the recent merger of Tesla and Solar City the residential market will now be introduced to home battery storage systems. This will now reduce the need for dependence on the national energy grid. Sustainable homeowners are now able to couple power generating solar technology with rechargeable lithium batteries. These lithium storage batteries will allow sustainable homeowners to store the electricity that is generated during the day and use it during the night, survive energy black outs, live off the energy grid and become totally energy independent!



Currently only five percent of homeowners choose to use home energy storage systems. As the battery storage system rapidly evolves, with new technology this practice will be commonplace. Battery storage systems venture capitol funding has jumped from 30 million dollars in 2015 to over one billion dollars in 2017. New technology  includes a portable lithium storage battery that now weighs less than 10 pounds! Lithium storage batteries can now charge your hybrid vehicles, further mitigating climate change effects from fossil fuels. As with all new technology the initial price is high and comes down as the technology advances. Residential battery storage currently cost between $1,000-2,000 per kilowatt. Approximately $10,000 for a 6 kilowatt battery system. Battery storage systems are eligible for a 30% federal investment tax credit and state tax credits which vary by state. California SGIP rebates are based upon the size of battery storage system. Tax incentives can drop the initial cost of a 19 kilowatt system from $32,000 to $12,000 dollars which can now be financed with the energymortgage!

As these knowledgeable green appraisers implement and utilize these comprehensive uniform green underwriting tools nation wide, the green data will be published in the various 800+ MLS (multiple listing service) nationwide to provide comparable green appraisal compsbench marked to conventional residential values. As the green comparable (comps) are accumulated, there is now preliminary nascent documented bench marking evidence that a green communities home can now add from a 5.6% added resale value to an Atlanta, Georgia green communities home and up to 9% added resale value in a California green communities home. This is significant financial comparable data as acknowledged unsophisticated conventional real estate brokers, appraisers, home builders and news media outlets  have previously failed to accurately represent, publish and correctly value your green communities home nationwide.

What was previously undocumented, considered confusing and nebulous is now solidified, third party documented and bench marked. This documented increased premium value is  significant as the increased green appraisal value can completely cover the selling/listing commission for your green communities home! A $400,000 dollar green communities home with a 9% increased green value is $36,000 dollars! So a knowledgeable green appraiser/green broker tandem pays you financial dividends for their specialized green knowledge …directly benefiting your family and your personal pocketbook! With aggregated green data, green features and information collection comes power and knowledge! Now when this green appraisal package is properly assembled your family is now prepared to receive the added financial benefits of the green mortgage. It has been believed by the public at large for longer than a decade that green building costs more than conventional building. While this statement may sometimes be true. Green building could cost from (1-5%) more than conventional construction.  This nominal  additional up front building cost is retained and added to the resale asset value of  green communities home. Then we consider that green certified homes spend less time on the resale market, have improved indoor thermal comfort, consume less energy and water.  Buyers now prefer and are seeking out these energy efficient homes with their intrinsic lower operating costs, water conservation savings, healthier lifestyle and then we can factor in nebulous climate change benefits which are now shaping financial polices worldwide as witnessed by the recent 2016 Paris agreement.

The World bank has recently stated that green buildings are the easiest and most efficient way to reduce climate change effects! Reduced annual operating costs effect the green appraisal market value and market capitalization of residential and commercial properties. With lower operating costs the commercial property has a higher market value. After the eight year financial debacle from the George W. Bush administration corporations were unable to raise their prices due to market pressure. The only option left was for corporations to cut operating costs, overhead, layoffs, marketing, and outsourcing etc. Certified green building is now becoming a market competitive differentiator, required by sustainable tenants, documented improved employee productivity, structuring green leases, higher property market capitalization, lower annual operating costs, resulting in a higher resale value.



Some of these new commercial green buildings are now constructed to net zero real estate status. Consuming as much energy and recycled water as they produce. Using connected internal sensors to monitor all types of energy systems (HVAC, lighting, water) on an hour by hour basis. This allows for real time monitoring to a computer database. When their is a malfunction it shows up immediately and can be repaired quickly reducing energy waste. Additional features now include energy storage systems. This allows storage of excess energy produced during the day to be used in less peak hours. As corporations are now moving along the triz scale to embrace sustainability green building has now moved towards the forefront on a global scale.

Sustainable brokers are commercial property specialists in green knowledge, certified green building, certified wellness real estate, green leasing, and  fulfilling corporations sustainability objectives/goals. Well certified buildings are now scientifically documented showing a minimum 60% improved employee productivity for indoor knowledge based employees. Building on the initial success of the Residential green addendum. On February 11, 2015 the Appraisal Institute (AI) release companion form 821 the Commercial Green Energy Efficient Addendum. Designed specifically for Commercial real estate evaluations. Focusing on energy efficient and water conservation features which can account for up to 35% of the annual operating expenses of  commercial properties. These individual features can now be itemized and documented in an expanded section of the commercial green addendum. The resulting NOI net operating income effects the commercial properties capitalization rate which determines the green appraisal value of the property.



Commercial Green And Energy Efficient Addendum (pdf file) 

It’s important to remember that green building is an evolving industry in constant changing and market flux. The industry’s tools are developed in hindsight not foresight. All green underwriting tools require accepted accredited standards and take decades to come to realization and market acceptance. There is specific areas of territory evidence which will eventually lead to formalized accepted standardized documentation in commercial green appraisal analysis that will effect the green appraisal monetary value of commercial buildings in the future.

Such future areas may include: Indoor air quality (IAQ), employee productivity, Living walls effect on employee productivity. Individual tenant operating expenses, sub metering. Cloud data, energy dashboards, and wireless sensors. Healthy building materials disclosure and declarations. Energy storage systems. Over the next decade all of these items may eventually be recognized for their intrinsic value, and used by green appraisers! is the first green portal to connect and document all the related vertical industries, starting with the green appraisers, greenbrokers, greencontractors, greenmortgages, greenira, greenpolicyholders and the emerging green securities using smart convergence direct navigation keyword technology.

Previously, all of the individual industries operated in “silos” separated industries, adding confusion to the publics/business perception of documented increased financial and productivity value for green building. Allowing the term green washing to be coined and used. articulates  how each green industry is integrated, dependent and aligned with all of the other vertical green industries, working cohesively which benefits the sustainable homeowner or sustainable corporation financially!
