Open Regional Fund – Energy Efficiency (GIZ)
Open Regional Fund – Energy Efficiency (GIZ) Calculating energy savings in the 2nd NEEAP How M&V&E project results can help? Training workshop on the preparation of the 2nd NEEAP Vienna, 05/10/2012 11.10.2012 Seite 1 Page Recommended methods Top-down indicators for monitoring trends in energy efficiency Bottom-up formulae for calculating energy savings 11.10.2012 Seite 2 Page TD indicators – basic info Reflect overall final energy consumption trends rather than savings resulting from specific energy efficiency improvement measures Implicitly reflect all energy savings (not onyl additional) Capture savings from horizontal and soft measures otherwise hard to evaluate 2009 as a starting year Savings from early actions to be taken into account by BU methods and added to TD results (avoiding double counting) 3 levels recommended by the EC: P: subsector level A: if data for P are missing M: when P and A cannot be applied Eurostat data suffice for M indicators! 24 recommended indicators for 4 sectors: residential, services, industry and transport 11.10.2012 Seite 3 Page TD indicators – what do you already have? Excel template developed by EIHP with: Input data for calculation of TD indicators and savings according the EC Manual (for 2009 and 2010) Simple end-use model for household (energy consumption for heating, cooking, appliances) and transport sector (number of cars) Energy consumption of households for space heating in toe per floor area in m2 adjusted for climatic conditions (P1) heating E HSH MDD 25 ∗ heating F ADD EHSH F MDD heating ADD heating P1 Energy consumption of households for space heating in toe per floor area in m2 adjusted for Serbia Serbia Serbia Serbia Serbia toe/m2 2009 2.443,2 232.593.000 2.800 2.227 0,0132 The additional data necessary for calculation of indicator P1 (energy balance, statistical data): the number of permanently occupied dwellings the average dwelling size (m2) Serbia Serbia k m2 2.501,0 93 Final energy consumption in households - base year: Share of energy consumption in total energy - base year: Final energy consumption for space heating Final energy consumption for water heating Final energy consumption for cooking Final energy consumption for air conditioning Final energy consumption for electricity appliances (including lighting) Serbia Serbia Serbia Serbia Serbia Serbia share share share share share share 1,000 0,680 0,068 0,145 0,005 0,102 Serbia Serbia share share 0,072 0,030 Serbia ktoe 2009 3591 Energy consumption of households for space heating in year t Total floor area of permanently occupied dwellings in year t Long-term mean heating degree days over the last 25 years Actual heating degree days in year t Final energy consumption for electricity appliances (excluding lighting) Final energy consumption for lighting Final energy consumption in households: ktoe m2 2010 0,0 0 2.882 #DIV/0! 2010 2011 0,0 0 #DIV/0! 2011 11.10.2012 Seite 4 Page TD indicators – advanced training available in November 2012! EIHP will update inputs and calculations for 2009 and 2010! Extend calculation for 2011! 1 (late start due to planned arrival of participants in the morning): DayTraining focusing on how to get data for indicators! 1. Welcome by GIZ representative with overview of M&V&E project achievements and plans for futureagneda: Draft 2. Introduction to the workshop by the Consultant 3. Croatian experiences in top-down calculations within 2nd NEEAP 4. Dinner Day 2 (morning start – full day): 1. Calculation of top-down indicators for households 2. Calculation of top-down indicators for service sector 3. Lunch 4. Calculation of top-down indicators for industry Day 3 (morning start – only morning session due to planned departure of participants): 1. Calculation of top-down indicators for transport 2. Lunch 3. Conclusions of the workshop 11.10.2012 Seite 5 Page BU methods – basic info EC provided: Set of formulae, baselines, lifetimes and default values 11 methods for building sector M&V&E project provided CPs with proposals of national methodologies 11.10.2012 Seite 6 Page National methods EC recommended methods Refurbishment measures in existing buildings Insulation refurbishment measures applied to building components Introduction of building codes Replacement of heating supply equipment in buildings Installation or replacement of water heating installations Installation or replacement of air conditioning split systems (< 12 kW) Solar water heating Replacement or new household appliances Replacement or new lamps in residential buildings Replacement or new lighting systems in tertiary buildings Replacement or new office equipment Replacement or new public lighting systems Improvement of central air conditioning systems Installation of heat pump Replacement or new vehicles Eco driving Modal shift Energy audits Connection of existing or new building to district heating system Biomass boilers Energy efficient electric motors Variable speed drives Smart meters + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + Ser Mon Mac Kos Cro EEI measure Alb BU methods – country specific info + + + + 11.10.2012 Seite 7 Page + + + + + + + + + + + BU methods – data requirements and possibilities Specific final energy consumption before – after direct measurement with corrections estimate with model Program specific final energy consumption before-after baselines available National average final energy consumption before-after baselines available 11.10.2012 Seite 8 Page BU methods - baselines Baselines determined for three types of measures: replacement, retrofit without replacement, acquisition of new equipment/construction of new building National methodologies contain baselines – use them in the lack of specific data! Stock average Market inefficient Market efficient 11.10.2012 Seite 9 Page BU methods – what is already available to you? All country methods with baselines available from M&V&E project Summarized in the Final report 11.10.2012 Seite 10 Page BU methods – data sources Direct measurements before-after Rarely available, except in case of ESCO projects Normalization needed Bills from distribution companies and retailers before-after Normalization needed Equipment sales data (e.g. appliances, CFLs) Rarely available in CPs Engineering estimates (with and without inspections) Probably the most important source! Modeling Building statistics Energy certificates databases Data from implementing bodies (funds, agencies, donors) Request data from them! Surveys (housing, market) 11.10.2012 Seite 11 Page BU methods – data collection What can you do? Define your data needs according to measures and methods to be used for their evaluation - > national BU methodologies provide you guidelines about data needs! Timely send out calls to stakeholders for delivery of data (use this for other purposes as well, e.g. to find out about activities on the supply side) Define deadlines for data delivery Other ministries Local authorities Agencies, funds Energy companies Donors You will for sure need to ‘chase’ stakeholders! No magic recommendation Up to you how to handle this issue Start now! 11.10.2012 Seite 12 Page BU method – examples from Croatia Public lighting – very easy example Metered data before-after available from the users of the Fund and from ESCOs No need to use formula with default values Tips: Require data from local authorities (usually there are separate bills for public lighting) Think in advance – how can you improve your methodology and data collection system (e.g. asking only for road lenght)?
