To comply with UNICEF global strategies to reduce the environmental footprints of its offices through the internal procedures and operations, UNICEF Iran has aimed for an energy audit of its office building to identify the gaps in terms of energy efficiency and to find out solutions accordingly. In this respect, an evaluation of various energy-consuming operations and procedures as baseline assessment to determine energy-saving opportunities is needed. Moreover, the audit will determine and assess any wasteful and energy-conserving practices, operations and procedures and recommend adjustments to improve wasteful and maintain/reinforce energy-conserving practices/operations.
Scope of Work:
- Review the existing operational characteristics of the building: Through a series of meetings and site visits, identify the operating characteristics of the facility, energy system specifications, operating and maintenance procedures, preliminary areas of investigation, unusual operating constraints, anticipated future expansions or changes, training needs and other concerns related to facility operations.
- Review existing documentation and management practice: All available facility documentation is reviewed by site representatives (where possible). This documentation should include all available architectural and engineering plans, facility operation, Interviews with facility managers/engineers, UNICEF EFAAT reports and maintenance procedures and logs, and utility bills for the current and previous year. The review should cover at a minimum:
Building energy intensity (e.g. heating, cooling & lighting systems):
- Fuel sources
- Maintenance contracts
- Building energy management policies (if any)
- Maintenance reports
- Maintenance budgets
- Utility bills
Revised 30 November 2021:
- Characteristics of the Building Automation System (if any) especially on monitoring of electricity consumption
- Detailed inspection of site and preliminary energy audit: After a thorough review of the construction, operation and management documentation, the major energy consuming processes in the facility are further investigated. The inspection and energy audit shall focus on all passive and active systems available on site.
- Formulation of Investment Grade Audit report: Upon the completion of the preliminary audit report and installation of the necessary energy monitoring tools/equipment on site for data collection, an Investment Grade Audit (IGA) report is to be produced for submission to UNICEF and the building owner. The report will recommend a series of no/low, medium and high investment grade measures. The IGA will look into details of technical measures including the economic benefits of implementing them. IGA report will also propose suitable financing modality including its approach for bankable proposals.
- The methodology requires a clear focus on the objective of improving overall energy utilization. This will be achieved through coordination with stakeholders, document review, facility inspection, utility analysis, energy calculations, economic analysis, data collection, desk research, interviews, meetings, report writing and so forth.
- The UNICEF project team will not provide any equipment or technicians in executing the audit measurements. The consultant must sufficiently resource himself/herself in carrying out the audit work (where it shall be included in the Financial Proposal).
Investment Grade Energy audit report of the building to review and analyze existing operational and management characteristics of the building, including current GHG emission level, as baseline assessment. The report must provide a description of the methodology employed, equipment used, calculations, charts, findings and recommendations for energy efficient retrofits justified/accompanied with a cost and benefit analysis of the recommendations. The report shall address potential energy saving including the amount of GHG emission reduction. The report should address at a minimum the following (where possible):
- a. Calculation of existing building energy intensity
- Inventory of high impact energy consuming equipment
- Review of purchased fuels sources
- Review of utility bills and tariffs imposed
- Review of operational procedures and constraints
- Review of maintenance contracts
- Revised 30 November 2021
- Review of energy policies
- Review of maintenance reports
- Review of maintenance budgets
- Review of training regimes
- Recommendations of no/low, medium and high investment grade measures.
- Potential energy savings including amount of GHG emission reduction.
- Orientation and footprint
- Window shading/glazing levels
- Window design and leaks
- Day light
- Natural ventilation
- Air conditioning system (fan coils, air handling units, pumps, water temperatures, coefficient of performance, temperature, carbon dioxide emission levels, relative humidity levels and air change)
- Boilers or hot water systems (flue gas, insulation and steam)
- Lighting (operating schedules, zoning, lux levels, power densities)
- Ventilation system and Indoor air quality
- Building automation system (operational characteristics, maintenance requirements and accuracy)
- Small power or plug loads
- Lifts and escalators (operating schedule, harmonics, motors)
- Electric supply and distribution (distribution profile, harmonics, power quality, power factor, maximum demand), emergency power systems efficiency and possible alternatives
Qualifications of the Successful Contractor:
- Selection will be made based on review of technical capacity and the financial offer provided by the consultant. In terms of technical capacity, the Consultant is required to have the following eligibility criteria:
- Minimum of master’s degree in a relevant Engineering discipline
- Minimum of 5 years of experience in energy audit
- Knowledgeable in energy policies and energy management procedures
- Ability to analyze technical requirements in energy efficiency and energy management applications,
- Ability to analyze organizational policies and procedures,
- Strong analytical skills.
- Fluency in Farsi
