Rebuilding After Katrina: Smart Energy Choices

Rebuilding After Katrina: Smart Energy Choices

Energy efficiency has been part of the American lexicon since 1978 when the Energy Policy Act was first enacted. Since then, energy efficient homes and increased use of replaceable energy resources have become the norm in states like New York and California. Policies and programs have supported these statewide efforts while $847 million in federal funding has recently been allocated to help homeowners across America build better homes. nevertheless, some parts of the country continued to use outmoded housing codes and practices already when it was no longer considered sustainable. The Gulf Coast vicinity of Louisiana, Mississippi, and Alabama was such a place. There is no way to know how many of the homes in the Gulf Coast vicinity were inefficient prior to the hurricane. However, the gap between best practice and actual practice was revealed as Hurricane Katrina came ashore along the Gulf Coast and many Americans glimpsed the sub-standard housing that been the position quo in the vicinity for years.

in addition in this disaster, there is an opportunity synchronous with recent changes in building policies. For example, in September 2005, the new Energy Policy Act was passed by Congress into law. The International Code Council (the ICC, an agency setting the standards for U.S. buildings) likewise upgraded its IECC 2006 codes for new homes . And the government-sponsored ENERGY STAR program of the United States Environmental Protection Agency (EPA) amended its guidelines for new homes in October 2005 . Luckily, the policies for a right rebuild are in place. Now, a sound financial justification for making smart energy choices is needed since 310,353 new single family homes must be built in the affected regions closest.

By using a complicate suite of DOE-2 modeling analyses along with climate, census, and emergency management data from Louisiana, Mississippi, and Alabama, this paper makes the case for an energy efficient rebuild. This modeling compared the impacts of rebuilding homes that may have been built to minimum building codes (as a baseline for comparison) versus four increasingly more energy-efficient standards . While the quick payback scenario illustrated the fastest payback considering the initial investment, the 2006 ENERGY STAR New Homes Guidelines showed the most reasonable short-term payback with larger savings over time. For example, the initial investment of $900 million to rebuild 310,353 homes to the ENERGY STAR guidelines would have a payback of just 7.5 years–much less than the term of the mortgage.

Due to the increased quality of the home and short return-on-investment, the ENERGY STAR scenario is recommended as the minimum threshold for single family homes during the rebuild. Additionally, the annual electricity savings (using this scenario) would avoid the equivalent of one South Carolina nuclear plant , and reduce greenhouse gas emissions equivalent to taking 51,221 cars off the roads.

On August 29, 2005, at 6:10 a.m., a Category 4 hurricane made landfall near Buras, Louisiana, with 145 mph winds. By 9:00 a.m., New Orleans Lower Ninth District was under 8 feet of water and a path of destruction the size of the United Kingdom had been produced and leaving 1.5 million people without strength. The number of parishes affected in Louisiana was 31, in Mississippi 47 counties were affected, and in Alabama 8 counties saw damage to their single family housing units of 2.1 million. By October 2005, an estimated 2.2 million people had registered for aid from the Federal Energy Management Agency (FEMA) and 416,852 people were nevertheless without strength in Texas and Louisiana .

An estimated 160,000 new single-family homes will need to be built in the coming months in New Orleans alone, with a grand total of 310,353 single family homes needing to be built in the three states.

fleeting History of the Gulf Coast Areas Single Family Housing
After the Civil War, men known as carpet baggers came into the Gulf Coast vicinity, taking advantage of a ravaged countryside and its people. In the 140 years since the Civil War, the Gulf Coast vicinity was populated and an estimated 2 million single family homes built in the affected vicinity. By 2000, the average cost of those homes was $71,685, nearly $48,000 less than the average single-family home in America . These homes were not only cheaper than the typical U.S. house, they were also older, with an average build-date of 1975.

The people in the Gulf Coast areas affected by Hurricane Katrina were more unprotected than the average populace in America. The percent of the population living on incomes at or below the poverty line in the parishes and counties affected by the hurricane was 19% of the population. The average age of those homes was not only three decades but the relative energy efficiency (as compared the national average) was lower than the norm. The Gulf Coast vicinity hit by Hurricane Katrina had a history of lagging behind the rest of the country in terms of infrastructure, housing quality, and economic robustness. In short, the vicinity was mature for the kind of disaster the hurricane wrought.

After Hurricane Katrina, a new copy of carpet baggers set upon the Gulf Coast vicinity, once again attempting to take advantage of a ravaged countryside and weary populace. But unlike the post-Civil War years, todays opportunists are local. Suppliers from drywall to roofing materials are inflating material costs and large-extent builders are vying to hire every able-bodied worker capable of swinging a hammer. in addition some large retailers are taking an active stewardship role in the reconstruction. For example, The Home Depot and its suppliers have partnered to donate nearly $1.2 million of products to those areas in need, along with $4 million in donations from the Home Depot Foundation . Meanwhile, Congress is seeking to pass bills to protect contractors from litigation that might consequence from workers in this polluted, dangerous area that is todays Gulf Coast. The time to anticipate the impacts of smarter choices for the rebuild is now.

Datasets and Modeling Software
Housing characteristics, including construction kind, architectural characteristics, and quantity of construction from the 86 counties and parishes in the three hardest-hit states (Louisiana, Mississippi, and Alabama) were gleaned from 2000 Census Bureau data. Modelers established a baseline of what existed pre-Katrina using DOE-2 modeling software to compare the economic and environmental benefits of rebuilding in an energy efficient manner. For the ease of modeling a representative sample, only single-family homes units were considered since 67% of the homes destroyed were this housing kind. method Cost Data aided in modeling the per unit cost to rebuild each home for each scenario. NAHB data described the housing starts projections for 2005-2010 while additional economic characteristics for the vicinity were gathered from the 2000 U.S. Census.

Codes and Standards
The codes climate in these three states gave a snapshot of what would be functional to expect during the rebuild. As of August 29, 2005, the local codes for energy efficiency in the three states were based on standards as recent as the year 2000 and as old as 1975 . However, recent code revisions have made an energy efficient rebuild possible. For example, the newly-revised IECC 2006 of the International Codes Council was considered in one scenario. And since the government-sponsored ENERGY STAR program of the EPA amended its New Homes Guidelines in October 2005 , and those guidelines are effective beginning January 1, 2006, those guidelines were considered as another scenario.

Options for the Gulf Coast Rebuild
Four scenarios were chosen for modeling, against a baseline set at the form Energy Code 1993 (MEC 93). In this baseline, it was assumed that all houses destroyed had indeed been constructed to a code standard that was approximately a decade old. in addition, as can be seen from a cursory review of the codes for these states, it is probable that many of these houses were not built to such a recent code. Nonetheless, the baseline was established as if the home had a window solar heat gain coefficient (SHGC) of 0.58, a wall R-value of 13, an attic R-value of 23, an air conditioner Seasonal Energy Efficiency Rating (SEER) of 10, and an estimated size of 2,000 s.f.

Using datasets of several thousand factors and applying those factors to the four basic upgrades in energy efficiency, researchers modeled 72,000 DOE-2 runs to characterize the impacts in two climate zones, and eight cities in the Gulf Coast vicinity affected. This modeling provided the baseline for a plain vanilla single-family housing unit in the three states on August 29th, 2005, for comparison with four energy efficiency upgrades.

The estimated number of homes requiring demolition and rebuild has been estimated to be as many as 2.1 million single family homes. As mentioned, this study modeled only those homes utterly obliterated. It produces mentioning that the cost estimates for constructing new homes with these upgrades must be considered estimates only. The cost of materials, regional labor cost differences, the value of money, the cost of electricity or gas, and many other factors might affect these building costs and consequently, the simple payback period estimates.

With that disclaimer in mind, in terms of the cost to upgrade, Scenario 4 proved to be the most expensive initial investment, at $6,003 per home. This initial cost put the simple payback period at about 12.5 years. in addition when this payback period is considered within the context of a 30-year mortgage, that return-on-investment appears more popular. The next most costly upgrade was Scenario 3 (ENERGY STAR) at a cost $2,754 per home. in addition the ENERGY STAR scenario had a much quicker payback than Scenario 4 (Best Practices) or the less expensive option, Scenario 2 (IECC 2006). The simple payback period for Scenario 3 (ENERGY STAR) was just 7.5 years.

The lesser expensive option was Scenario 2, IECC 2006. This option cost an estimated $1,511 to upgrade the home, in addition paid back the initial investment in 8.5 years. The most rapid return-on-investment was found to be the Quick Payback scheme outlined in Scenario 1. The initial investment of $527 paid for itself in just over 2 years. However, due to the without of envelope and insulation considerations, the quick payback scenario is not recommended for the rebuild.

For the Gulf Coast rebuild, the opportunity to build energy efficient single family homes is clear: a right rebuild will have long-term benefits to the homeowners, the local utilities, the vicinity, and the nation. For homeowners, building homes that have tight envelopes, good insulation, proper windows, and energy efficient equipment will reduce their monthly energy bills and increase the comfort and health of the occupants. The assistance of reduced energy bills cannot be understated. In present-day Mississippi, 34% of the household income pays the mortgage. The second-highest cost is energy bills.

As consumer energy bills rise, some regions are more challenged than others. For example, a study in North Carolina found that of every 100 trailers sold, 20 were repossessed. The problem was not mortgage costs that were too high, rather, the problem was that the monthly energy costs were more than the mortgage. With utility bills as high as $230 a month, the 30-year mortgage on a $25,000 mobile home was minor in comparison.

The fragility of the household incomes in the Gulf Coast vicinity certainly plays a part in calculating what ought to be re-built there. The average annual energy bills for the vicinity were around $1,200. Scenario 3 (ENERGY STAR) returns a higher amount than the Quick Payback scenario, for example. For that, and other reasons, ENERGY STAR 2006 is the recommended threshold for the rebuild. In other words, there should be no single family home re-built with government-assisted funding that does not conform to the ENERGY STAR for New Homes Guidelines, as a minimum.

Load Reduction
The simple payback period for each rebuild scenario was calculated (based on incremental annual utility bill savings) without considering rising costs of electricity (which increased 3.3% in this vicinity in the past year) or rises in crude oil prices (which rose 64% in the past year). In the recommended scenario (ENERGY STAR), an estimated 713 MW yearly would be avoided, approximately equal to one nuclear strength plant serving Hartsville, South Carolina . The increased benefits in savings for local strength plants, and the environmental benefits (in an already-challenged vicinity) would be reduced greenhouse gases in the form of CO2 equivalent to removing 51,221 cars from the roads . And for every 1 MW avoided, an estimated $1 million is saved, and similar savings are achievable in reduced dispensing costs.

Better Health
As the rebuilding of the Gulf Coast continues, building energy efficient homes by the 2006 ENERGY STAR for New Homes Guidelines (along with the Indoor Air Package guidelines being piloted) ensure that occupants of these new homes will use less on medical-related problems and mold-remediation costs long associated with poor construction techniques in hot, humid climates. When considering that indoor air pollution is responsible for one death every 20 seconds , and that the economic impacts of indoor pollution have been estimated at billions of dollars a year , spending a little more on each home to avoid these costs is money well-spent.

Louisiana Homeowners
Homeowners in Louisiana can access the Louisiana Home Energy Rebate Option (HERO) program, the Home Energy Loan Program (HELP), the character Tax Exemption, or the Qualified Allocation Plan (QAP) program for rebuilding assistance or tax incentives. In general, the HERO program only requires that homes be built 30% better than the 1995 MEC, an outdated standard; and its cash assistance amounts to an energy efficiency premium up to $2,000. The HELP program, a program of the Louisiana Department of Natural Resources, precludes a homeowner from participating in the HERO program and largely consists of home improvement loans to make energy-related improvements to existing homes.

The Department of Natural Resources (DNR) offers to finance half of the improvements at 2% interest, up to a maximum of $6,000 on the DNR portion. character tax exemptions are obtainable for owner-occupied home equipment that is energy efficient. The QAP program awards points to projects that include energy efficient products, including windows, doors, HVAC, and appliances.

The government should make these budgets obtainable for leverage in the rebuilding efforts.

Mississippi Homeowners
Mississippis homeowners can access the Energy Rated Homes of Mississippi Program or the Green strength Switch Generation Partners Program for rebuilding assistance. In the former, five levels of energy efficiency are given to homes, based on the Uniform Energy Rating System. The benefits to the homeowners are unclear. The Green strength Switch Generation Partners Program, a program under the Tennessee Valley Authority (TVA) and participating distributors. Under this program, homeowners are offered a dual-metering option. Homeowners may generate strength, feeding excess back to the grid. TVA will buy the complete output of a qualifying system and the homeowner receives credit for the strength generated.

The government should make these budgets obtainable for leverage in the rebuilding efforts.

Alabama Homeowners
Alabama homeowners may access the Income Tax Credit Program, the State Grant Program, or the Qualified Allocation Plan (QAP) program for rebuilding or tax credit incentives. In general, Alabama homeowners can receive an income tax credit for converting their main energy source for a home to replaceable energy resources (for heating only). The State Grant Program is directed largely at biomass projects for industrial and commercial enterprises; and it is unclear if the government will consider rebuilding residential areas as a government program that would be eligible to use this program. chiefly, the program gives assistance in the form of loans with interest rates no higher than 2% above the chief rate (with maximum interest subsidy payment amount not to go beyond $75,000). The QAP program awards points for projects that promote energy conservation by exceeding standards of the Council of the American Building Officials form Energy Code (MEC).

The government should make these budgets obtainable for leverage in the rebuilding efforts.

Federal Legislation that Aids Homeowners in All Three States
The most effective financing tool obtainable to homeowners in all Gulf Coast regions affected by the hurricane may be found in the recent federal legislation of the U.S. government. On August 8, 2005, the Energy Policy Act of 2005 was enacted. This law includes various sections related to enhancing the energy use of citizens and industry. Among the Acts elements are tax credits for energy efficiency. If homeowners along the Gulf Coast opt to build energy efficiently, they will receive incentives to do so. Were homeowners to build to 2006 ENERGYSTAR for New Homes Guidelines are recommended, homeowners could receive tax incentives. Unlike the state or local programs (cited above), the federal budget allocation is substantial: $50 million per year by FY2008.

For builders of new homes, the Energy Policy Act of 2005 (Section 1332) provides a credit up to $2,000 for a home that saves at the minimum 50% compared to the 2004 IECC code , and $1,000 for an ENERGYSTAR manufactured home. The applicable dates for these incentives are calendar years 2006 and 2007.

For owners of existing homes, the Energy Policy Act of 2005 (Section 1333) includes a credit for homeowners for 10% of the cost of installing building envelope elements consistent with the IECC code. There is no certification required. The credits are obtainable for calendar years 2006 and 2007.

The home tax credit has an overall per household cap of $500 to reimburse homeowners for the following expenses:
o 10% of the cost for energy efficient insulation, doors, and/or ENERGYSTAR high reflectivity roofs
o 10% (up to $200) of the complete cost of energy efficient windows
o Up to $300 of the complete cost for purchasing a highly-efficient central air conditioner, furnace, heat pump, or water heater
o Up to $150 of the complete cost of a highly-efficient furnace or boiler, and
o Up to $50 of the complete cost of a furnace with a highly-efficient fan.

popular Mortgage Rates for Rebuilding in the Gulf Coast vicinity
As homeowners in the affected areas seek to rebuild, they will look for mortgage rates that will help them build homes they can provide to function. In Louisiana, Mississippi, and Alabama energy efficient mortgages (or EEMs) are obtainable by agencies like Fannie Mae. In Louisiana and Mississippi, these mortgages are obtainable from EnergyWise Mortgage and Indigo Financial Group. In Alabama, these mortgages may be obtained from American Acceptance Mortgage, EnergyWise Mortgage, or the Indigo Financial Group. In general terms, EEMs allow homeowners to borrow funds to make energy improvements at the time of buy of a home. The average annual savings to homeowners is $300 to $600. Fannie Mae should extend the EEMs to rebuilding homes damaged during the hurricane.

1) The 2006 ENERGY STAR for New Homes Guidelines are the recommended threshold for all new single family homes construction undertaken during the rebuild.
2) State and local incentives should be leveraged for all new homes construction during the rebuild.
3) Federal tax credits and federal funding should be leveraged for all new homes construction during the rebuild to multiply the impacts.
4) EEMs programs (and other similar initiatives) should be extended to include new homes construction needed for the rebuild.
5) The financial benefits that accrue due to smart energy choices taken during the rebuild should be tracked to build a larger case for energy efficient development and later mass deployment of energy efficient practices.

This research demonstrates that the decisions made in the coming months will impact the economics and resources of households, utilities, the vicinity, and the nation for several decades to come. As strength suppliers struggle to rebuild damaged infrastructure like strength dispensing systems, and every local provider of materials and manpower is stretched to its limits, there is no better time to reduce the eventual load on manpower and infrastructure than now. Homeowners will assistance from reduced energy bills while area builders will find a whole new business form in setting themselves except plain vanilla builders as they position themselves as ENERGY STAR builders.

Of course, rebuilding an area this large will not be easy. But as this study proves, rebuilding single family housing to an energy efficiency standard that is higher than what it was makes sound economic sense and forms the most logical strategy for creating a sustainable re-construction. The incentives under the new tax credits bill, energy efficient mortgages, and state-centered incentives and financing–when supplemented with federal funds for the rebuild–only add to the financial benefits of making smart energy choices in the Gulf Coast rebuild. already without these benefits, rebuilding the 310,353 homes to ENERGY STAR standards would be an investment that pays for itself quickly, and returns another $3.2 billion dollars into the local economy in just 30 years. Imagine what might be attained by making similarly intelligent energy choices for the other 2.1 million new homes needing to be built.
