ATTACHMENT 14
to: J.B.
Culpepper, Planning Director
from: John Richardson, Long Range/Sustainability
Planner
subject: South Grove Energy Management Plan
date: March 4, 2008
This memorandum is intended to provide detailed background
information and recommended stipulations for the applicant’s latest version of
the South Grove Energy Management Plan.
The
applicant has most recently developed the second version of an Energy
Management Plan (EMP) which describes their intent to integrate energy
efficiency into both site design and homeowners’ association (HOA) documents in
order to monitor construction practices and encourage ongoing operating
efficiencies. The applicant also notes a commitment to building
homes which are at least 20% more energy efficient than the baseline
requirements of the ASHRAE standard for this type of housing product (i.e.,
single family). According to the EMP, this will be achieved through HOA
monitoring as well as sealed engineering calculations which will certify the
performance of each home and be submitted to both the Planning and Inspections
departments when building construction permits are sought.
The EMP
describes a strong involvement by the HOA in working towards energy efficiency
and conservation through construction as well as site design. For
example, it is noted that the HOA will work to minimize lawn area installations
and irrigation system sizes. Similarly, it is stated that the HOA will
encourage the use of rainwater cisterns in a manner which is consistent with
the development’s continuing goals of energy efficiency and conservation.
In light of the current drought conditions, staff finds these potential
measures to be both positive and in the vein of a more comprehensive form of sustainable
development.
As noted
above, the applicant has submitted two drafts of the EMP to staff. Prior
to the submission of the first draft, staff met with the applicant to review
the Council policy pertaining to energy efficiency and Energy Management Plans.
Additionally, the staff provided the applicant with a suggested framework for
developing an EMP which is consistent with the guidance given to other recent
applicants and provides a possible structure that addresses the specific
expectations of the Council policy found in Resolution 2007-04-23/R9, a policy
revised from Resolution 2001-11-12/R20.
As part of
staff’s evaluation of the first EMP, a series of comments were provided to the
applicant describing some of the suggested modifications and considerations for
the Plan. Such comments generally included the following:
- A request that the
applicant put the EMP into a framework which is more consistent with that
of other recent applicant’s EMPs. At present, the EMP is largely a
narrative which does not call attention to specific methods,
measures/elements or stipulations like other recent EMPs have done.
Placing the content of the EMP in staff’s suggested framework (which the
applicant has a copy of) will allow both staff and the review bodies to
more easily determine what can be expected versus what might only be
intended. Staff also believes that the suggested framework will
highlight the applicant’s intended measures more clearly and allow for
better comparison with existing and future EMPs.
- A request that the
applicant explain the mechanism which demonstrates that each home will
achieve a 20% greater level of energy efficiency as compared the baseline
requirements of the ASHRAE standard for this type of housing
product. Staff conveyed to the applicant that ENERGY STAR qualified
homes, the type of certification that may be sought after for each home in
the development, do not necessarily achieve the applicant’s 20% target
through the certification process.
- A request that the
applicant acknowledge and describe some consideration towards other
components of the Council energy efficiency policy which have not been
expressly noted in the EMP, such as:
- The production or
offset purchase of renewable energy sources through the NC GreenPower
program; and
- Assurances of
indoor air quality, adequate access to natural lighting and the allowance
of renewable energy.
- A request that the
applicant consider, in addition to the ENERGY STAR program, other green
building programs such as LEED for Homes or NC Healthy Built Homes which
can require higher baseline energy efficiencies (above ENERGY STAR) and
also provide a more comprehensively sustainable form of development.
DISCUSSION
In
response to the comments above, the applicant appeared to make only one modification
to the original EMP. This change is found at the end of the document and
describes the mechanism for how builders will provide evidence for a 20% energy
efficiency improvement above ASHRAE standards (noted above at the end of the
first paragraph in background section of this memorandum). Consequently,
staff believes it will be important for the applicant to agree to the
stipulations shown in the recommendation section of this memorandum below. We
believe the applicant’s success at complying with these recommended
stipulations will better demonstrate the intent of the Council policy regarding
energy efficiency and Energy Management Plans. Furthermore, staff would
submit that the recommended stipulations are reasonable in that they are
designed to provide for a more complete Energy Management Plan that is
consistent with what other applicants have recently provided to staff.
RECOMMENDATION
We recommend that the following stipulations be required of
the applicant.
- The applicant will revise the Energy Management Plan prior to the
issuance of a Zoning Compliance Permit, so as to put t in a framework that is
more consistent with other plans submitted to date. As part of this
revision, commitments to certain conservation measures by the applicant must be
shown as stipulations within the Energy Management Plan. The type and
number of commitments represented through these stipulations will be at the
applicant’s discretion; however, staff will provide additional comments if
these commitments fall short of the Council policy. In order to revise
the plan, the applicant can meet with staff to discuss the framework and/or use
the staff handout for guidance.
- As part of the applicant’s revisions to the framework of the Energy
Management Plan, the applicant must describe some consideration towards other
components of the Council energy efficiency policy which have not been
expressly noted in the current form of the EMP, such as:
- The production or offset purchase of renewable energy sources through
the NC GreenPower program; and
- Assurances of indoor air quality, adequate access to natural lighting
and the allowance of renewable energy.
- Because home energy rating specialists who work closely with builders
can most accurately determine the energy efficiency of a home once it is built,
the applicant should modify the suggested mechanism for assuring 20% greater
energy efficiency to indicate that sealed engineering calculations which
certify the performance of each home shall be submitted to both the Planning
and Inspections departments no more than 30 days after the Certificate of Occupancy
(CO) has been issued. This adjusts the suggested point of review for
sealed engineering calculations from the permitting stage to approximately one
month after the CO stage.
