DEPARTMENT: CITY ENERGY COMMITTEE.. CTY. MGR.G�
SUBJECT:
PROPOSED ENERGY ORDINANCE
STATEMENT OF THE -MATTER:
This item, for your consideration and review, is an ordinance regulating energy
conservation. It requires solar heating for all new swimming pools, requires
all new residential construction to be pre -plumbed for solar and requires other
energy conservation standards. This item was first reviewed by the City Council
in January of 1981.
ENVIRONMENTAL REVIEW
The Planning Director has determined that this project will not have any signif-
icant environmental impacts and has issued a Negative Declaration. The Negative
Declaration is attached and will require City Council action.
FISCAL IMPACT
There will be no direst fiscal impact to the city other than staff time
necessary to enforce the provisions of the ordinance. The increased demand on
staff time would be negligible. It is estimated that pre- plumbing a house for
solar equipment will add $200-500 per unit as opposed to $3,000-5,000 per unit
for the installation of solar equipment. Based on the available research,
requiring solar heaters for pools in this ordinance is cost- effective (see
attached memo).
The City Energy Committee recommends that the City Council certify the Negative
Declaration and that Ordinance No. i&_73 is introduced.

MEMORANDUM
DATE: July 20, 1981
TO: City Manager
FROM: Chairman City Energy Committee
SUBJECT: ENERGY CONSERVATION ORDINANCES
The primary reason for proposing this ordinance to require solar
heaters for new swimming pools is the natural gas savings. The
County of San Diego estimated in 1979 that 300-800 therms of nat-
ural gas per year could be saved if a similar ordinance were en-
acted. Total, non -pool gas consumption for homes using gas for
water and space heating is approximately 700 therms per year.
Therefore, pool heating represents a potential 40-100% increase
in gas consumption. Annual gas savings from this ordinance will
increase each year as more pools subject to its provisions are
built. However, as the price of natural gas increases the econo-
mic considerations of pool owners will have the same effect.
Cost analyses prepared for the County of San Diego ordinance in-
dicate that when a pool owner regularly uses a pool cover and
rarely uses the gas heater during the swim season (May-october),
a solar system would not be cost effective. However, if the
cover is not used and the pool is heated, a solar system is cost-
effective. (See Table 1)
Whether or not to adopt this ordinance involves more than deci-
sions based on cost-effectiveness. Energy savings and the long
term effects in stimulating conservation technology must also be
considered.
The fact that the ordinance may not prove cost-effective for peo-
ple who use their gas heater infrequently or who keep their pool
covered all the time would argue against the ordinance. However,
after weighing all the factors, the City Energy Committee recom-
mends adoption of this ordinance for the following reasons:
1. There would be a substantial savings in natural gas.
2. Pool heating may be considered a non -essential use of
natural gas.
3. Adoption of this ordinance would further encourage solar
technology development.
K
The other main feature of this ordinance, requiring all new resi-
dences to be pre-plumbed'for solar, was recommended by the City
Council earlier this year.

NEGATIVE DECLARATION
1200 ELM AVEI
CARLSBAD, CALIFOF
PROJECT ADDRESS/IACATION: Both items would be implemented city-wide..
PRWECT DESCRIPTION: It is proposed to amend Chapter 18.30 of the
Carlsbad Municipal Code to require an active or passive solar system
for all new swimming pools and requires other energy conservative
measures. An additional resolution is proposed to set standards for
passive solar design in subdivisions.
The City of Carlsbad has conducted an environmental review of the
above described project pursuant to the Guidelines for Implementation
of the California Environmental Quality Act and the. Environmental
Protection Ordinance of the City of Carlsbad. As a result of said
review, a Negative Declaration (declaration that the project will not
have a significant impact on the environ-nent) is hereby issued for the
subject project. Justification for this action is on file in the
Planning Department.
A copy of the Negative Declaration with supportive documents is on
file in the Planning Department, City Hall, 1200 Elm Avenue, Carlsbad,
CA. 92008. Continents from the public are invited. Please submit
comments in writing to the Planning Department within ten (10) days of
date of issuance.

MEMORANDUM
DATE: August 11, 1981
TO: CITY MANAGER
FROM: Building Official
SUBJECT: ORDINANCE 8093/CONSTRUCTION INDUSTRY FEDERATION
LETTER - 08-06-81
Mr. Kilkenny, in his letter dated August 3, 1981, recommended
three exceptions to Ordinance 8093. The Energy Committee has
reviewed these exceptions and offers the following comments:
Item 2 is a valid concern. It was never our intention to man-
date pre -plumbing on units that could not possibly benefit from
a future solar installation. If the Council believes that this
exception should be incorporated into the ordinance, an ordinance
modification will be prepared.
Items 1 and 3 propose waivers based on alternate energy sources
or future technology.
The Committee believes that staff and applicant time to process
these waivers would far exceed the minimum cost for pre -plumbing.
Cost effectiveness, in light of future increases in energy costs,
would be better determined by the homeowner who may choose to in-
stall a solar system.

Council Members 1
City Hall
1200 Elm Avenue
Carlsbad, CA 92008
Dear Mayor Packard and Council Members:
I appreciated the opportunity to testify before your Council
on August 4, 1981, regarding the proposed Energy Ordinance
and the Design Standards for Energy Conservation.
After the Council adopted the Energy Ordinance Vice Mayor
Casler suggested that, prior to second reading of the ordinance,
I convey through letter the concerns of CIF regarding the pre -
plumbing requirement. In response to the Vice Mayor's sugges-
tion, below is a brief discussion of our continued concerns.
Section 18.30.030 of the proposed ordinance requires that all
new residential units include plumbing designed to allow the
later installation of a solar water heating system. Mandating
pre -plumbing in all new residential units is unwise. Just
as your Council has provided flexibility in the Energy Con-
servation Design Standards by allowing for exceptions to the
standards, your Council should also allow for exemptions to
the pre -plumbing requirement.
Clearly not every new home constructed in Carlsbad will be
able to take advantage of solar energy. The configuration of
some existing parcels prohibits the desired building and roof
orientation. Other parcels are shaded by trees or neighboring
buildings. Still other applicants may have little reason to
install solar because similar or greater energy savings will
be achieved through other technologies.

It is therefore our recommendation that your Council modify
the ordinance to allow for exemptions under the following
conditions:
(1) The applicant can demonstrate to the satisfaction
of the Planning Director that solar water heating
is not cost effective for the subject project.
(2) The subject project is unable to accomodate solar
water heating because of physical impediments. (i.e.
shaded parcel, orientation of building/roof, con-
figuration of the parcel).
(3) The applicant can demonstrate to the satisfaction of
the Planning Director that the subject project will
achieve energy savings equal to or greater than those
projected for solar water heating through alternate
design or technology.
Your consideration of these remarks is appreciated.
Sincerely,
�r

future solar panel location to the area where the water heater is
located .
Insulation
All solar water piping shall be insulated in any areas that are not
heated'or cooled
EXCEPTION
The above will not be required Den the project cannot accomodate
solar water heating because of orientation, other structures shading
.the parcel or configuration of the parcel.
.EFFECTIVE DATE
These standards shall apply only to those residential dwelling units
for which a plan check fee was paid after the effective date of
Ordinance 8093.
