"LEED Interpretation" "10041" "2011-05-09" "New Construction, Schools - New Construction, Commercial Interiors, Core and Shell" "Is it acceptable for LEED NC 2.2 EAc5 M&V Plans to follow the concepts of the IPMVP but limit the savings analysis in an effort to control costs, if they provide ongoing accountability and meet or exceed owners\' M&V objectives?" "Meeting the owner\'s requirements and providing ongoing accountability of energy consumption alone do not satisfy the credit requirements. The M&V plan provided must be consistent with either Option B or Option D of IPMVP regardless of cost of implementation. Applicable internationally." "None" "None" "X" "LEED Interpretation" "2474" "2009-02-20" "New Construction, Commercial Interiors, Core and Shell, Schools - New Construction" "To meet the requirements of LEED-NC Version 2.2, EA Credit 5, we would like to use IPMVP Option C. This option is considered a low rigor option by the IPMVP because the baseline comparison in this case is with a group of buildings that are located on various sites and are supposedly similar in usage and type. In our case two identical buildings on the same campus are next to each other and have the same square footage, number of stories, size, orientation, type of use (office), the same owner and the same maintenance staff. The first building is under renovation to achieve Gold certification and the second building will be renovated in three years. It appears to us, that metering the two identical buildings simultaneously and using the actual old non-renovated building metrics as a baseline for the retrofit of the second renovated building, follows the intent, philosophy and purpose of the LEED EA Credit 5. In addition, this will give an incentive to the owner to continue with the renovation of the second building when energy savings are evaluated during the first year of operation. Is the use of the IPMVP Option C acceptable in this particular case?" "The applicant is requesting approval to develop a Measurement and Verification (M&V) plan based on IPMVP Option C. While it appears that the baseline building will more accurately represent the proposed building than most projects conducting M&V using IPMVP Option C, the proposed approach is not acceptable. Only whole-building level performance can be measured using IPMVP Option C. IPMVP Options B and D, in addition to being more accurate, allow for the measurement and verification of performance of each energy conservation measurement (ECM). Applicable Internationally. " "None" "None" "X" "LEED Interpretation" "2576" "2009-04-27" "New Construction, Commercial Interiors, Core and Shell, Schools - New Construction" "The statements of the IPMVP Volume III regarding Option D leave considerable room for interpretation. For example, Section 4.5.5 states, ""parameters that change daily or hourly may warrant continuous metering."" Individual task lights are an example of a modeled energy use that would likely change on an hourly basis. However, on average the task lighting may remain relatively stable when viewed at a whole building level. The term ""may"" is subject to interpretation by reviewers since some may interpret it to be a requirement, i.e., ""shall"", while others merely a suggestion. Additionally, the IPVMP does not stipulate at what level the continuous metering shall be installed. Our project is an office building that receives electricity, chilled water, and steam from a campus central energy plant. In anticipation of utilizing Option D of the IPVMP, our project plans to meter energy and water end use as follows: - Domestic water meter measuring flow in gallons per minute - Steam flow meter for building heating and domestic hot water measuring in pounds per hour - Chiller water flow meter measuring building cooling demand in gallons per minute and temperature change, i.e., BTU meter - Individual air handling unit VFDs measuring motor speed, motor current, output voltage and output frequency - Power meters at the main switchgear measuring volts, amperes, watts, volt-amperes, VARS, kilowatt-hours VAR-hours, demand kilowatts, power factor, frequency and harmonic distortion - Power meters at the distribution panelboards on each floor measuring volt, amperes, watts, volt-amperes, VARS, demand kilowatts and power factor Our project does not plan to individually meter any of the following energy end uses: - Lighting panels (lighting control system will monitor operating hours) - Task lighting - Process energy (office equipment, elevators, etc.) - Constant speed pump motors (DDC system will monitor runtime) Does this metering plan appear to meet the intent and requirements of the IPVMP Volume III and EA Credit 5? If not, what modifications are required to comply with the intent of the credit?" "The applicant is requesting guidance for determining the extent of individually metering needed to provide the necessary feedback for calibrating their as-built energy model (IPMVP Vol. III, Option D). Based on the description provided, it is not possible to make a determination if the metering plan fully satisfies the intent and requirements of IPVMP Volume III. While it appears that many of the end-uses and systems are sub-metered and the information will be necessary for calibrating the energy model, it should be noted that it is not necessary to sub-meter everything. Assess the level of metering to do the calibration. Since the task lighting is highly variable and a direct product of occupancy, as opposed to scheduled operations, it would be acceptable that the task lighting anticipated energy use be stipulated, as offered in IPMVP Vol. III Section 4.5.3. For EAc5 compliance, the M&V plan should address the methods and approaches that seem most appropriate for measuring and verifying energy use under IPMVP Option D. Applicable internationally.
