7 Regulatory Context Labelling program of appliances, collaboration with SLSI, NERDC Code of practice of EE buildings 2008 (commercial, industrial & large residential 4 or more stories, greater than 500m2, greater than 100 kva, greater than 350 kwth Cooling Cap), Voluntary Energy Manager/Auditor program (accreditation of energy manager auditor) for reporting of energy related info

8 Why Energy Labeling? Helping customer to recognize high h energy efficient i products during purchasing; Encouraging manufactures importers and suppliers to manufacture/ import/supply ppy high energy efficient products; Controlling low energy efficient products entering into the market.

9 Target appliances under energy labelling programme Year Electric Motor Room Air conditioner Refrigerator Tubular fluorescent lamp Fluorescent lamp bll ballast 2009 Ceiling fan 9 9

10 Regulations Mandatory requirements at the level of whole development controlling manufacture, import, store, sales and distribution of CFLs not conforming with the standards. energy label appearing on the container of the CFL. Regulations Gazetted up to Extraordinary Gazette No.1611/10 of the Democratic Socialist Republic of Sri Lanka dated 22 nd July 2009 Extraordinary Gazette No.1794/15 of the Democratic Socialist Republic of Sri Lanka dated 22 nd January

11 Information in the energy label

12 As at present, Impact of Energy labeling - CFLs CFL Penetration Level (having at least one lamp at a house) is 76% 30,000 (Source: National Survey on Household Lighting by ADB) 20,000 CFL imports are stabilized IFLimports are decreasing Number of lamp ps (in '000) CFL and IFL Imports 35,000 CFLs IFLs 25,000 15,000 10,000 5,000 A reduction of 300 MW with respect to the decreased use of IFL is being maintained Year

17 Code of Practice for Energy Efficient Buildings The Government of Sri Lanka recognizes that improving energy performance of buildings is an important part of the strategy of the country s sustainable energy development process. Code of Practice for Energy Efficient Buildings, the guideline document compiled by SS SLSEA for this purpose was introduced d into the building approval process of the Urban Development Authority. Under this scheme three buildings have been certified. Energy saving potential by gy g p y adopting Code of Practice for Energy Efficient Buildings for 10 year period is 215 GWh

18 General Principles Envelop Element Climatic Zones Warm Humid (DBT,WBT) Warm Dry (DBT,WBT) Uplands (DBT,WBT) Building Typology Day Time operation (Offices, Shops) Extended Operations (Hotels, Hospitals, Super Markets)

19 Mandatory Requirements Principally based on U-values of roofs, facades, fenestrations Envelop Sealing Air Leakage (5 lit/s m2, 2 lit/s m2) Exiting National Building regulations (regulations for min levels of Natural Ventilation & Daylight use)(prescriptive values are from Similar Standards)

20 Prescriptive Requirements External walls with/without fenestrations Visual Light Transmittance (VLT>0.15) OTTVi values for Facades Formula for OTTVi will be used U-values from Appendices or calculated using actual properties Solar Correction factor (CF) Combined Shading Coefficient (SC)

21 Roof Prescriptive Requirements Exterior roof solar absorptivity (a < 0.4) OTTVi values Roofs Formula for OTTVi will be used;wwr=0 U-values from Appendices or calculated using actual properties p

22 Compliance Method All stated Mandatory requirements shall be met Area weighted Cumulative OTTV shall be estimated using calculated OTTV i values for each element of the building envelop Area weighted Cumulative OTTV for the whole Building Envelop < 50 W/m 2 (Threshold value) 22

23 Submission Procedure VB-XL based environment for estimating OTTV for the whole building envelop Pertaining data with drawings Data on air leakage 23
