Preface

This guide to climate zones is an update to Volume 7 in the Best 

Practices series of guides for home builders produced by the U.S. 

Department of Energy’s Building America Program. This guide 

describes the climate zone designations used by Building America 

and compares them with the climate zone designations used in the 

International Energy Conservation Code (IECC). 

Building America welcomes reader feedback on all volumes of the 

Best Practices Series. Please submit your comments via e-mail to

BUILDING AMERICA BEST PRACTICES SERIES
Guide to Determining Climate 

Regions by County

This report describes the climate zone designations used by the 

U.S. Department of Energy Building America Program. The report 

is intended as an aid in helping builders to identify the appropriate 

climate designation for the counties in which they are building. The 

guide can be used in conjunction with the Best Practices builders’ 

guides produced by the DOE Building America Program to help 

builders determine which climate-specific Best Practices guide 

they should use.

The eight U.S. Building America climate regions described here 

are based on the climate designations used by the International 

Energy Conservation Code (IECC) and the American Society of 

Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). 

The IECC climate zone map was developed by DOE researchers 

at Pacific Northwest National Laboratory with input from 

Building America team members, in particular Joseph Lstiburek 

of Building Science Corporation.a,b The IECC map was developed 

to provide a simplified, consistent approach to defining climate for 

implementation of various codes; it was based on widely accepted 

classifications of world climates that have been applied in a variety 

of different disciplines. The PNNL-developed map was adopted by 

the IECC and was first included in the IECC in the 2004 Supplement 

to the IECC. It first appeared in ASHRAE 90.1 in the 2004 edition. 

The IECC map divided the United States into eight temperatureoriented climate zones. These zones are further divided into three 

moisture-oriented moisture regimes designated A, B, and C. Thus 

the IECC map allows for up to 24 potential climate designations. 

In 2003, with direction from the Building America teams, researchers 

at DOE’s National Renewable Energy Laboratory simplified the 

IECC map for purposes of the Building America Program, into eight 

climate zones. For reporting purposes, these are further combined 

into five climate categories: Hot-humid, hot-dry/mixed dry, mixedhumid, marine, cold/very cold, and subarctic.c

The Building America and IECC climate maps are shown in Figures 

1 and 2. The climate regions are described below. Climate zone 

boundaries follow county boundary lines. A listing of counties 

comprising each climate zone is provided below, beginning on page 5. 

The climate region definitions are based on heating degree days, 

average temperatures, and precipitation as follows: 

The table at the end of this document 

contains the complete listing of U.S. 

counties in alphabetical order by state, 

then county, and then Building America 

climate region.

Heating Degree Days

The degree-day measurement is the 

difference in temperature between the 

mean (average) outdoor temperature 

over a 24-hour period and a given 

base temperature for a building space, 

typically 65°F (25°C in Canada). For 

example, if the mean temperature 

at a given location for January 3 is 

35°F, then the heating degree days 

measurement for that day is 30 

(65 - 35 = 30).

Hot-Humid

A hot-humid climate is defined as a region that receives more than 

20 inches (50 cm) of annual precipitation and where one or both of 

the following occur:

•	 A 67°F (19.5°C) or higher wet bulb temperature for 3,000 or more 

hours during the warmest six consecutive months of the year; or

•	 A 73°F (23°C) or higher wet bulb temperature for 1,500 or more 

hours during the warmest six consecutive months of the year.

The Building America hot-humid climate zone includes the portions 

of IECC zones 1, 2, and 3 that are in the moist category (A) below 

the “warm-humid” line shown on the IECC map. 

Mixed-Humid

A mixed-humid climate is defined as a region that receives more than 

20 inches (50 cm) of annual precipitation, has approximately 5,400 

heating degree days (65°F basis) or fewer, and where the average 

monthly outdoor temperature drops below 45°F (7°C) during the 

winter months.

The Building America mixed-humid climate zone includes the 

portions of IECC zones 4 and 3 in category A above the “warmhumid” line. 

Hot-Dry

A hot-dry climate is defined as a region that receives less than 

20 inches (50 cm) of annual precipitation and where the monthly 

average outdoor temperature remains above 45°F (7°C) throughout 

the year.

The Building America hot-dry climate zone corresponds to the 

portions of IECC zones 2 and 3 in the dry category.

Mixed-Dry

A mixed-dry climate is defined as a region that receives less than 

20 inches (50 cm) of annual precipitation, has approximately 5,400 

heating degree days (50°F basis) or less, and where the average 

monthly outdoor temperature drops below 45°F (7°C) during the 

winter months.

The Building America mixed-dry climate zone corresponds to IECC 

climate zone 4 B (dry).

Cold

A cold climate is defined as a region with between 5,400 e and 9,000 

heating degree days (65°F basis).

The Building America cold climate corresponds to the IECC climate 

zones 5 and 6.

Very-Cold

A very cold climate is defined as a region with between 9,000 and 

12,600 heating degree days (65°F basis).

The Building America very cold climate corresponds to IECC 

climate zone 7.

Subarctic

A subarctic climate is defined as a region with 12,600 heating degree 

days (65° basis) or more. The only subarctic regions in the United 

States are in found Alaska, which is not shown in Figure 1.

The Building America subarctic climate zone corresponds to IECC 

climate zone 8.

Marine

A marine climate is defined as a region that meets all of the 

following criteria:

•	 A coldest month mean temperature between 27°F (-3°C) and 65°F (18°C)

•	 A warmest month mean of less than 72°F (22°C)

•	 At least 4 months with mean temperatures higher than 50°F (10°C)

•	 A dry season in summer. The month with the heaviest 

precipitation in the cold season has at least three times as much 

precipitation as the month with the least precipitation in the 

rest of the year. The cold season is October through March in 

the Northern Hemisphere and April through September in the 

Southern Hemisphere.

The Building America marine climate corresponds to those portions 

of IECC climate zones 3 and 4 located in the “C” moisture category.

Research and 

Development of Buildings

Our nation’s buildings consume 

more energy than any other sector 

of the U.S. economy, including 

transportation and industry. 

Fortunately, the opportunities to 

reduce building energy use—and 

the associated environmental 

impacts—are significant.

DOE’s Building Technologies 

Program works to improve the 

energy efficiency of our nation’s 

buildings through innovative new 

technologies and better building 

practices. The program focuses 

on two key areas:

• Emerging Technologies 

Research and development of 

the next generation of energyefficient components, materials, 

and equipment

• Technology Integration of new 

technologies with innovative 

building methods to optimize 

building performance and savings
