Residential Buildings

Focus Area 2: Residential Buildings Summary

f-a-2

Energy consumed in residential buildings accounts for 19% of City of Atlanta’s total GHG emissions. Improving the efficiency of our residential building stock will contribute significantly to achieving City of Atlanta’s greenhouse gas reduction target, while saving residents money on utility bills and reducing the need for new infrastructure. This chapter focuses on opportunities to retrofit existing residential buildings, increase the quality of new construction, and to ensure that future activities in these sectors are compatible with our community’s climate protection goals.

RB 1-Subsidies /Rebates Offer financial incentives for residential energy retrofits Stage
Work with utilities to expand energy efficiency rebates program such as the Georgia Power Energy Efficiency Home Improvement Rebates that expired in 12/31/2012. The program provided 50% of the cost of whole house improvements up to $2,200 and for individual improvements up to $700 (http://energy.gov/savings/georgia-power-energy-efficiency-home-improvement-rebates).

Work with the State of Georgia to expand programs such as the Clean Energy Tax Credit for clean energy equipment installed and placed into service. For clean energy property installed for single-family residential purposes, the tax credit is equal to 35% of the cost of the system (including installation). The credit is subject to various ceilings depending on the type of system. A maximum of $2,500 per residence for domestic solar water heating, a maximum of $10,500 per residence for photovoltaic (PV), active space heating and wind energy systems, and a maximum of $2,000 per installation for Energy Star-certified geothermal heat pumps (http://energy.gov/savings/clean-energy-tax-credit-personal).

RB 1- Utility Programs Offer financial incentives for energy efficient appliances Stage
Continue working with utilities to provide economic incentives to replace inefficient appliances for efficient ones. As an example, Georgia Power Appliance program offers rebates for the replacement of room air conditioners, refrigerators, clothes washers, and freezers. moderate
RB 1- HERS Home Energy Rating System (HERS) Stage
The Home Energy Rating System (HERS) Index is the industry standard by which a home’s energy efficiency is measured. It’s also the nationally recognized system for inspecting and calculating a home’s energy performance. Based on the results, an energy-rated home will receive a HERS Score. The HERS Index Score can be described as a sort of miles-per gallon sticker for houses. In addition to a HERS Index Score, a home energy rating also provides the homeowner an insight as to how the home ranks in terms of energy efficiency. moderate
RB 1- Finances On-bill Financing Stage
Utilize an Energy Services Company (ESCO): ESCOs conduct a comprehensive energy audit for a facility and identify improvements to save energy. In consultation with the owner, the ESCO designs and constructs a project that meets Owner’s needs and arranges the necessary funding. The ESCO guarantees that improvements will generate energy/utility cost savings sufficient to pay for the project over the term of the contract. moderate
The Property Assessment Clean Energy (PACE) is a municipal program funded via issuance of public bonds or private lenders. The bonds are secured by a property lien and repaid via special property taxes (also known as Environmental Upgrade Agreements (EUA)). moderate

>RB 1-New Homes

high-impact
Ensure new residential constructions are built to maximize energy efficiency and include energy efficiency measures available such as sub-metering
RB 2- Code Compliance Enhance residential building code enforcement and compliance in new residential buildings to achieve 100% compliance by 2020 Stage
Effective January 1, 2011, Georgia’s residential energy code is the 2009 International Energy Conservation Code (IECC) with specific amendments to Georgia.

Sub-metering: According to the National Science and Technology Council Committee on Technology, sub-metering of multifamily residences enables the improved performance of new buildings – sub-metering provides the operations and maintenance transparency necessary to enable more efficient management of energy. In addition, sub-metering can drive behavioral change related to energy conservation.
