4 1 Introduction 1.1 Site Visit Organisation Name: Site Name & Address: Names of buildings included: SEAI Client ID: Dates of Visit: SEAI Energy Advisor: EA name EA employer EA address EA phone number Visit Hosted By: Energy Advisor undertook an EPC Assessment of the Facility Name under the Sustainable Energy Authority of Ireland s (SEAI) Public Sector Energy Performance Contract Programme. To include a brief summary of the visit areas toured, focus of discussions, etc. 1.2 Objective The objective of the assessment is primarily to assess the viability of implementing an Energy Performance Contract by: Identifying a suitable energy performance indicator for existing and target energy use to quantify the potential for energy savings. This will also help assess the impact of the energy conservation measures in achieving this potential. Identifying a suite of measures, including savings and implementation budget, which together are of sufficient scale and combined payback to create a financially viable project suitable for EPC. Where appropriate, non-energy savings, such as water or maintenance, will also be quantified. Identifying essential client requirements to be incorporated in the works (such as replacement of windows). Savings and implementation budget figures will be provided. Identifying other benefits, including renewal of plant which has reached end of life or resolution of comfort issues. These may need to be quantified. Identifying additional metering and recording requirements, including any environmental conditions, that are likely to be required for EPC baseline data. The associated installation budget will be included. This EPC Site Assessment is not an Investment Grade Audit and has been completed in a relatively short period of time with using readily available site information, sector 4

5 performance indicators, and rules of thumb. It is a concise, or walk-through survey. It has been prepared with all reasonable skill, care and diligence and summarises the findings from the site assessment. All figures are indicative. The contents of this report provide the basis for completion of the EPC Project Development Brief - Stage Description of Site & Scope of Assessment To include a brief overview description of site location, age, size, activities, staff levels, shift system etc Building Name Floor Area (specify if Gross Internal or Total Useful Floor Area) Year of construction (for applicable building regulations) BER / DEC Rating Comments This assessment includes the following utilities: Electricity Other utilities 1.4 Essential Works To include any works the client regards as an essential element to include in any EPC. 5

Fuel Electricity Imported Onsite Electricity Generation (e.g. CHP) Electricity Exported Quantity [kwh] Spend CO2 Spend Quantity (excl. Emissions (excl. [kwh] VAT) [t] VAT) CO2 Emissions [t] Additional Information Natural Gas LPG Fuel Oil (HFO / MFO) Kerosene / Gasoil Solid Fuels Renewables Fleet Total Table 1: Annual Energy Consumption & Energy Costs More detailed data to be included in an attached spreadsheet or the appendices. 6

Description of the main energy consumers at the site Table 2: Summary of Primary Electrical Energy Consumers Electrical Energy Consumer e.g. compressed air, chillers, motors & drives, air conditioning, space heating etc. e.g. compressed air, chillers, motors & drives, air conditioning, space heating etc. e.g. compressed air, chillers, motors & drives, air conditioning, space heating etc. e.g. compressed air, chillers, motors & drives, air conditioning, space heating etc. % of Total Comments Table 3: Summary of Primary Thermal Energy Consumers Thermal Energy Consumer e.g. process steam, process hot water, domestic hot water etc. e.g. process steam, process hot water, domestic hot water etc. e.g. process steam, process hot water, domestic hot water etc. e.g. process steam, process hot water, domestic hot water etc. % of Total Comments 2.3 Energy Performance Indicators (EnPIs) Details of EnPIs in use at site - definitions & recent values. Bar chart comparison energy use to sector benchmarks where available for an indication of existing performance and potential for savings. DEC rating, where available, for an indication of both potential and the amount of progress made to date. 7

8 3 EPC Scope and Expected Savings 3.1 Recent/Existing Energy Saving Initiatives Summary of energy saving initiatives that have been implemented at the site (if any). 3.2 Suggested Opportunities for Energy Savings We identified a number of opportunities for further energy savings at the site; these are summarised in Table 4 overleaf, with further detail in Section 4. The focus has been on measures suitable for implementation by EPC and those identified by the client as essential works (Section 1.4). The savings below are valued using the Average Unit Prices for the most recent year or from SEAI Fuel Cost Comparison. All utility prices and savings are calculated exclusive of VAT. 8

11 5 Baseline Data Requirements 5.1 Utilities To implement an EPC it is necessary to have a mechanism to Measure and Verify energy savings. An M&V plan is prepared by the ESCO later in the process, but the ESCO will need energy baseline data against which to compare future energy use. Having regard for the need to measure and verify savings in the future, it is essential have the necessary metering and monitoring infrastructure in place, and to begin gathering energy baseline data. This is the Client s (i.e. your) responsibility. The following metering and monitoring requirements have been identified. Meter Location & Area Metered Monitoring requirements 5.2 Environmental Conditions In order to avoid future issues as to whether or not an area or building was under or over heated before works take place, baseline environmental data is required. The extent of data requirements depends on the sensitivity of the occupants/activity to variations in temperature (and relative humidity) and the characteristics of the building (is it relatively homogenous with a high thermal mass and well-balanced heating system, or prone to having hot/cold spots). The following environmental data should be recorded. Sensor Location & Area Metered Monitoring requirements Insert additional information here or in Appendices. 5.3 Activity Metrics To include here any activity metrics that should be recorded, the frequency/recording interval, and the mechanism by which they will be recorded. 11

12 6 Conclusions & Next Steps Advice, Mentoring & Assessments for the Public Sector To insert chart of existing energy/m2 versus proposed versus typical versus good practice for each utility. Total investment budget Expected savings Simple payback To identify un-quantified benefits. years To discuss the viability of the above payback. To identify the factors that make this project viable or not. To include some observations on including or excluding some measures to improve payback, but the final mix of measures is up to the client. To identify any limitations of the assessment (e.g. lack of energy data) and, if appropriate, recommend revisiting the study after this has been resolved. To identify any special considerations and important assumptions. The reader is referred to the EPC Project Development Brief for the Client Name and Site for further steps. 12
