CLIMATE ZONE 1 FACTSHEET
SINGLE FAMILY
The California Advanced Homes Program (CAHP) provides
generous financial incentives for energy efficient residential
new construction projects and serves to help the California
Public Utilities Commission (CPUC) achieve two visionary
goals. The first goal is to help builders reach beyond the
current energy code and prepare for future code updates.
The second goal is to have all new construction homes reach
Zero Net Energy (ZNE) by 2020.
The CAHP score, generated in the compliance software,
indicates the overall energy efficiency of a home, and includes
all energy uses within the building. The CAHP score is on a
scale from 100 to zero. The lower the score, the more
efficient the home. To qualify for incentives, a home must
earn a CAHP score of 84 or less, submit an application with
compliance documents, and comply with program rules.
THE GOAL OF THIS SHEET
This climate zone fact sheet shows project teams the impact
a variety of energy efficiency measures have on the CAHP
score for a typical single family home in this climate zone.
Due to the diversity in California’s 16 climate zones, individual
efficiency measures will have varying results.
CLIMATE ZONE 1: ENERGY MEASURE IMPACT ON CAHP SCORE

Due to variations in home size, glazing, and equipment choices, the effects of each measure are
variable. CAHP Score impacts on this chart were generated from analysis on four single family
prototype buildings with a baseline equal to the 2013 Code prescriptive standard measure
package. Please contact a CAHP representative for review and analysis of specific projects.

CLIMATE ZONE 1
REFERENCE CITY: Eureka
This area is along the North Pacific coast. The northern
coastal region is a moist and cool climate that is
considered the coolest climate in California. Heating
dominates this climate zone with very minor cooling
needs. The energy efficiency measures with the largest
impact on the CAHP score include a high efficiency
tankless water heater, condensing furnace, and quality
insulation installation.
SINGLE FAMILY INCENTIVE STRUCTURE
$300 for an entry CAHP score of 84. Each
point is worth $100 down to a CAHP score
of 75. Each point below a CAHP score of
75 is worth an additional $200.
MEASURE DESCRIPTIONS
HIGH R-VALUE WALLS (R-23+4), U=0.049*: One of only four
measures that will become more stringent with the
upcoming 2016 code. The 2013 standard wall has a U-Factor
of 0.065 (R15+4 or R-13+5). In the 2016 code the
prescriptive standard U-Factor will change to 0.050.
ATTIC FLOOR INSULATION (R-49): Attic floor insulation helps
keep your home cooler in the summer and warmer in the
winter. Increasing the insulation level at the attic floor has
minimal incremental costs and will improve the efficiency
and csomfort of your home.
HIGH PERFORMANCE ATTICS & DUCTS IN CONDITIONED
SPACE*: Another measure slated to become part of the
upcoming 2016 code. Builders can either improve the attic
environment (by adding a layer of insulation along the roof
deck in addition to the traditional attic floor insulation) or get
the ducts out of the attic altogether. Both options greatly
reduce the operating costs of the HVAC system.
HIGH AFUE CONDENSING FURNACE (95% AFUE): The
efficiency of a furnace is measured by the Annual Fuel
Utilization Efficiency (AFUE). The higher the AFUE, the
greater the efficiency of the furnace.
AIR CONDITIONING SYSTEM (15 SEER, 13 EER): The efficiency
of an air conditioning system is measured by the Seasonal
Energy Efficiency Ratio and the Energy Efficiency Ratio. The
greater the EER and SEER, the more efficient the AC system.
The Federal Standards for HVAC systems less than 45,000
Btu/hr is 14 SEER, 12.2 EER.
Trademarks are property of their respective owners. All rights reserved.
WHOLE HOUSE FAN: A whole house fan can greatly reduce
the energy needed to cool a home. When outside
temperatures cool down to a comfortable level, the whole
house fan is used to rapidly bring cool outdoor air into the
house. The whole house fan is prescriptively required in
climate zones 8-14. For these climate zones, the chart shows
a CAHP Score penalty from not installing a whole house fan.
TANKLESS HOT WATER HEATER (EF = 0.82 / EF = 0.95)*: The
efficiency of a typical residential water heater is measured by
the Energy Factor (EF). The higher the EF, the greater the
efficiency of the water heater. Tankless water heaters are
particularly helpful in coastal climates with lower heating and
cooling needs.
QUALITY INSULATION INSTALLATION (QII)*: Properly installed
insulation is critical for a home to perform as designed. This
measure ensures proper insulation installation by having a
third party HERS Rater inspect and verify.
GLAZING (U-FACTOR = 0.28, SHGC = 0.22): The U-factor and
Solar Heat Gain Coefficient (SHGC) determine the efficiency
of glazing products. Lower U-factor and SHGC coefficients
mean less heat gets through the window through conduction
and solar radiation. Colder coastal climate zones may benefit
from high SHGC values due to reduced winter heating loads.
2016 CODE PREPARATION: Be prepared and build to the 2016
Code early! Take the measures marked with an asterisk (*),
plus building tightness of <3.0 ACH50 and earn a 5 point
kicker.

reduce the operating costs of the HVAC system.
HIGH AFUE CONDENSING FURNACE (95% AFUE): The
efficiency of a furnace is measured by the Annual Fuel
Utilization Efficiency (AFUE). The higher the AFUE, the
greater the efficiency of the furnace.
AIR CONDITIONING SYSTEM (15 SEER, 13 EER): The efficiency
of an air conditioning system is measured by the Seasonal
Energy Efficiency Ratio and the Energy Efficiency Ratio. The
greater the EER and SEER, the more efficient the AC system.

WHOLE HOUSE FAN: A whole house fan can greatly reduce
the energy needed to cool a home. When outside
temperatures cool down to a comfortable level, the whole
house fan is used to rapidly bring cool outdoor air into the
house. The whole house fan is prescriptively required in
climate zones 8-14. For these climate zones, the chart shows
a CAHP Score penalty from not installing a whole house fan.
TANKLESS HOT WATER HEATER (EF = 0.82 / EF = 0.95)*: The
efficiency of a typical residential water heater is measured by
the Energy Factor (EF). The higher the EF, the greater the
efficiency of the water heater. Tankless water heaters are
particularly helpful in coastal climates with lower heating and
cooling needs.
QUALITY INSULATION INSTALLATION (QII)*: Properly installed
insulation is critical for a home to perform as designed. This
measure ensures proper insulation installation by having a
third party HERS Rater inspect and verify.
GLAZING (U-FACTOR = 0.28, SHGC = 0.22): The U-factor and
Solar Heat Gain Coefficient (SHGC) determine the efficiency
of glazing products. Lower U-factor and SHGC coefficients
mean less heat gets through the window through conduction
and solar radiation. Colder coastal climate zones may benefit
from high SHGC values due to reduced winter heating loads.

The California Advanced Homes Program (CAHP) provides
generous financial incentives for energy efficient residential
new construction projects and serves to help the California
Public Utilities Commission (CPUC) achieve two visionary
goals. The first goal is to help builders reach beyond the
current energy code and prepare for future code updates.
The second goal is to have all new construction homes reach
Zero Net Energy (ZNE) by 2020.
The CAHP score, generated in the compliance software,
indicates the overall energy efficiency of a home, and includes
all energy uses within the building. The CAHP score is on a
scale from 100 to zero. The lower the score, the more
efficient the home. To qualify for incentives, a home must
earn a CAHP score of 84 or less, submit an application with
compliance documents, and comply with program rules.
THE GOAL OF THIS SHEET
This climate zone fact sheet shows project teams the impact
a variety of energy efficiency measures have on the CAHP
score for a typical single family home in this climate zone.
Due to the diversity in California’s 16 climate zones, individual
efficiency measures will have varying results.
CLIMATE ZONE 6: ENERGY MEASURE IMPACT ON CAHP SCORE

CLIMATE ZONE 10
REFERENCE CITY: Riverside
This area encompasses Southern California hilltops and
valleys. There is a substantial swing in winter and
summer temperatures compared to the adjacent coastal
climate zones with cold winters and hot summers.
Significant heating and cooling are needed in this climate
zone. The energy efficiency measures with the largest
impact on the CAHP score include high performance
attics, ducts in conditioned space, and a high efficiency
tankless water heater.
SINGLE FAMILY INCENTIVE STRUCTURE
$300 for an entry CAHP score of 84. Each
point is worth $100 down to a CAHP score
of 75. Each point below a CAHP score of
75 is worth an additional $200.
MEASURE DESCRIPTIONS
HIGH R-VALUE WALLS (R-23+4), U=0.049*: One of only four
measures that will become more stringent with the
upcoming 2016 code. The 2013 standard wall has a U-Factor
of 0.065 (R15+4 or R-13+5). In the 2016 code the
prescriptive standard U-Factor will change to 0.050.
ATTIC FLOOR INSULATION (R-49): Attic floor insulation helps
keep your home cooler in the summer and warmer in the
winter. Increasing the insulation level at the attic floor has
minimal incremental costs and will improve the efficiency
and csomfort of your home.
HIGH PERFORMANCE ATTICS & DUCTS IN CONDITIONED
SPACE*: Another measure slated to become part of the
upcoming 2016 code. Builders can either improve the attic
environment (by adding a layer of insulation along the roof
deck in addition to the traditional attic floor insulation) or get
the ducts out of the attic altogether. Both options greatly
reduce the operating costs of the HVAC system.
HIGH AFUE CONDENSING FURNACE (95% AFUE): The
efficiency of a furnace is measured by the Annual Fuel
Utilization Efficiency (AFUE). The higher the AFUE, the
greater the efficiency of the furnace.
AIR CONDITIONING SYSTEM (15 SEER, 13 EER): The efficiency
of an air conditioning system is measured by the Seasonal
Energy Efficiency Ratio and the Energy Efficiency Ratio. The
greater the EER and SEER, the more efficient the AC system.
The Federal Standards for HVAC systems less than 45,000
Btu/hr is 14 SEER, 12.2 EER.
Trademarks are property of their respective owners. All rights reserved.
WHOLE HOUSE FAN: A whole house fan can greatly reduce
the energy needed to cool a home. When outside
temperatures cool down to a comfortable level, the whole
house fan is used to rapidly bring cool outdoor air into the
house. The whole house fan is prescriptively required in
climate zones 8-14. For these climate zones, the chart shows
a CAHP Score penalty from not installing a whole house fan.
TANKLESS HOT WATER HEATER (EF = 0.82 / EF = 0.95)*: The
efficiency of a typical residential water heater is measured by
the Energy Factor (EF). The higher the EF, the greater the
efficiency of the water heater. Tankless water heaters are
particularly helpful in coastal climates with lower heating and
cooling needs.
QUALITY INSULATION INSTALLATION (QII)*: Properly installed
insulation is critical for a home to perform as designed. This
measure ensures proper insulation installation by having a
third party HERS Rater inspect and verify.
GLAZING (U-FACTOR = 0.28, SHGC = 0.22): The U-factor and
Solar Heat Gain Coefficient (SHGC) determine the efficiency
of glazing products. Lower U-factor and SHGC coefficients
mean less heat gets through the window through conduction
and solar radiation. Colder coastal climate zones may benefit
from high SHGC values due to reduced winter heating loads.
2016 CODE PREPARATION: Be prepared and build to the 2016
Code early! Take the measures marked with an asterisk (*),
plus building tightness of <3.0 ACH50 and earn a 5 point

The California Advanced Homes Program (CAHP) provides
generous financial incentives for energy efficient residential
new construction projects and serves to help the California
Public Utilities Commission (CPUC) achieve two visionary
goals. The first goal is to help builders reach beyond the
current energy code and prepare for future code updates.
The second goal is to have all new construction homes reach
Zero Net Energy (ZNE) by 2020.
The CAHP score, generated in the compliance software,
indicates the overall energy efficiency of a home, and includes
all energy uses within the building. The CAHP score is on a
scale from 100 to zero. The lower the score, the more
efficient the home. To qualify for incentives, a home must
earn a CAHP score of 84 or less, submit an application with
compliance documents, and comply with program rules.
THE GOAL OF THIS SHEET
This climate zone fact sheet shows project teams the impact
a variety of energy efficiency measures have on the CAHP
score for a typical single family home in this climate zone.
Due to the diversity in California’s 16 climate zones, individual
efficiency measures will have varying results.

CAHP Score impacts on this chart were generated from analysis on four single family prototype buildings
with a baseline equal to the 2013 Code prescriptive standard measure package. Please contact a CAHP
representative for review and analysis of specific projects.
Incentives for single family homes start at $300 for a CAHP score of 84. Every point between 84 and 75 is

of 0.065 (R15+4 or R-13+5). In the 2016 code the
prescriptive standard U-Factor will change to 0.050.
ATTIC FLOOR INSULATION (R-49): Attic floor insulation helps
keep your home cooler in the summer and warmer in the
winter. Increasing the insulation level at the attic floor has
minimal incremental costs and will improve the efficiency
and csomfort of your home.
HIGH PERFORMANCE ATTICS & DUCTS IN CONDITIONED
SPACE*: Another measure slated to become part of the

environment (by adding a layer of insulation along the roof
deck in addition to the traditional attic floor insulation) or get
the ducts out of the attic altogether. Both options greatly
reduce the operating costs of the HVAC system.
HIGH AFUE CONDENSING FURNACE (95% AFUE): The
efficiency of a furnace is measured by the Annual Fuel
Utilization Efficiency (AFUE). The higher the AFUE, the
greater the efficiency of the furnace.
AIR CONDITIONING SYSTEM (15 SEER, 13 EER): The efficiency
of an air conditioning system is measured by the Seasonal
Energy Efficiency Ratio and the Energy Efficiency Ratio. The
greater the EER and SEER, the more efficient the AC system.
The Federal Standards for HVAC systems less than 45,000
Btu/hr is 14 SEER, 12.2 EER.

a CAHP Score penalty from not installing a whole house fan.
TANKLESS HOT WATER HEATER (EF = 0.82 / EF = 0.95)*: The
efficiency of a typical residential water heater is measured by
the Energy Factor (EF). The higher the EF, the greater the
efficiency of the water heater. Tankless water heaters are
particularly helpful in coastal climates with lower heating and
cooling needs.
QUALITY INSULATION INSTALLATION (QII)*: Properly installed
insulation is critical for a home to perform as designed. This
measure ensures proper insulation installation by having a
third party HERS Rater inspect and verify.
GLAZING (U-FACTOR = 0.28, SHGC = 0.22): The U-factor and
Solar Heat Gain Coefficient (SHGC) determine the efficiency
of glazing products. Lower U-factor and SHGC coefficients
mean less heat gets through the window through conduction

CLIMATE ZONE 15 FACTSHEET
SINGLE FAMILY
The California Advanced Homes Program (CAHP) provides
generous financial incentives for energy efficient residential
new construction projects and serves to help the California
Public Utilities Commission (CPUC) achieve two visionary
goals. The first goal is to help builders reach beyond the
current energy code and prepare for future code updates.
The second goal is to have all new construction homes reach
Zero Net Energy (ZNE) by 2020.
The CAHP score, generated in the compliance software,
indicates the overall energy efficiency of a home, and includes
all energy uses within the building. The CAHP score is on a
scale from 100 to zero. The lower the score, the more
efficient the home. To qualify for incentives, a home must
earn a CAHP score of 84 or less, submit an application with
compliance documents, and comply with program rules.
THE GOAL OF THIS SHEET
This climate zone fact sheet shows project teams the impact
a variety of energy efficiency measures have on the CAHP
score for a typical single family home in this climate zone.
Due to the diversity in California’s 16 climate zones, individual
efficiency measures will have varying results.

Due to variations in home size, glazing, and equipment choices, the effects of each measure are variable.
CAHP Score impacts on this chart were generated from analysis on four single family prototype buildings
with a baseline equal to the 2013 Code prescriptive standard measure package. Please contact a CAHP
representative for review and analysis of specific projects.
Incentives for single family homes start at $300 for a CAHP score of 84. Every point between 84 and 75 is
worth an additional $100. Each point below a CAHP score of 75 is worth an additional $200. Please refer
to the back page for more information about the 2016 Code Preparation measures.

CLIMATE ZONE 15
REFERENCE CITY: Brawly
This is the low desert area of Southern California.
Winters are moderately cold and summers are extremely
hot and dry. Average temperatures are much higher
than all other zones in California. Some heating is
required and very large amounts of cooling are required.
The energy efficiency measures with the largest impact
on the CAHP score include high performance attics, ducts
in conditioned space, and a high efficiency AC system.
SINGLE FAMILY INCENTIVE STRUCTURE
$300 for an entry CAHP score of 84. Each
point is worth $100 down to a CAHP score
of 75. Each point below a CAHP score of
75 is worth an additional $200.
MEASURE DESCRIPTIONS
HIGH R-VALUE WALLS (R-23+4), U=0.049*: One of only four
measures that will become more stringent with the
upcoming 2016 code. The 2013 standard wall has a U-Factor
of 0.065 (R15+4 or R-13+5). In the 2016 code the
prescriptive standard U-Factor will change to 0.050.
ATTIC FLOOR INSULATION (R-49): Attic floor insulation helps
keep your home cooler in the summer and warmer in the
winter. Increasing the insulation level at the attic floor has
minimal incremental costs and will improve the efficiency
and csomfort of your home.
HIGH PERFORMANCE ATTICS & DUCTS IN CONDITIONED
SPACE*: Another measure slated to become part of the
upcoming 2016 code. Builders can either improve the attic
environment (by adding a layer of insulation along the roof
deck in addition to the traditional attic floor insulation) or get
the ducts out of the attic altogether. Both options greatly
reduce the operating costs of the HVAC system.
HIGH AFUE CONDENSING FURNACE (95% AFUE): The
efficiency of a furnace is measured by the Annual Fuel
Utilization Efficiency (AFUE). The higher the AFUE, the
greater the efficiency of the furnace.
AIR CONDITIONING SYSTEM (15 SEER, 13 EER): The efficiency
of an air conditioning system is measured by the Seasonal
Energy Efficiency Ratio and the Energy Efficiency Ratio. The
greater the EER and SEER, the more efficient the AC system.
The Federal Standards for HVAC systems less than 45,000
Btu/hr is 14 SEER, 12.2 EER.
Trademarks are property of their respective owners. All rights reserved.
WHOLE HOUSE FAN: A whole house fan can greatly reduce
the energy needed to cool a home. When outside
temperatures cool down to a comfortable level, the whole
house fan is used to rapidly bring cool outdoor air into the
house. The whole house fan is prescriptively required in
climate zones 8-14. For these climate zones, the chart shows
a CAHP Score penalty from not installing a whole house fan.
TANKLESS HOT WATER HEATER (EF = 0.82 / EF = 0.95)*: The
efficiency of a typical residential water heater is measured by
the Energy Factor (EF). The higher the EF, the greater the
efficiency of the water heater. Tankless water heaters are
particularly helpful in coastal climates with lower heating and
cooling needs.
QUALITY INSULATION INSTALLATION (QII)*: Properly installed
insulation is critical for a home to perform as designed. This
measure ensures proper insulation installation by having a
third party HERS Rater inspect and verify.
GLAZING (U-FACTOR = 0.28, SHGC = 0.22): The U-factor and
Solar Heat Gain Coefficient (SHGC) determine the efficiency
of glazing products. Lower U-factor and SHGC coefficients
mean less heat gets through the window through conduction
and solar radiation. Colder coastal climate zones may benefit
from high SHGC values due to reduced winter heating loads.

CLIMATE ZONE 16
REFERENCE CITY: Bishop
This area covers a large part of California and consists of
mountainous, semiarid regions with elevations above
5000 ft. Very cold weather dominates for more than half
the year although temperatures can vary due to
elevation and orientation. This zone has the highest
heating requirements in California and a very small
amount of cooling is needed. A high efficiency furnace
has the largest impact on the CAHP score in this climate
zone.
