3 Energy Efficiency Project (ENEV) Phase III A cooperation between Ministry of Energy Cabinet Secretariat SDC GIZ (BMZ) A general project presentation of the activities in the three components for Utilizing Energy Efficiency to demonstrate, develop, and improve Good Governance Page 3

4 Mongolian Partner: Cabinet Secretariat Outcome 1: Compliance with Budget and Procurement Laws relating to capital investments at local level has improved Outcome 2: Improved Energy Efficiency of public buildings in Khovd and Zavkhan aimags demonstrated Mongolian Partner: Cabinet Secretariat Mongolian Partner: Ministry of Energy Other Partners: Energy Regulatory Commission Outcome 3: Public institutions companies and households have intensified efforts and increased investments in the area of energy efficiency and energy conservation Budget: EUR 7,700,000 Shared by: BMZ (GIZ) SDC Page 4

5 What we are currently doing and what will be the results when this project phase is finished? Page 5

6 Improved Energy Efficiency of public buildings Improved qualifications of the private sector on the local levels for the implementation of energy efficiency projects Available evidence of the benefits from thermo-insulation of public buildings area Created a conducive environment for the rational and structured operation, maintenance and rehabilitation of public buildings Reached an agreement between the users of public building and heat suppliers on energy efficiency and energy savings based on a fact based dialogue Strengthened ability of the local government to develop action plans, standards and protocols, and capability to enforce them Page 6

7 What do you think is the main reason for the public buildings being cold? Heat loss 4% 16% 24% 17% Insufficient heating Expensive coal and insufficient supply Building quality 38% 1% Extreme cold temperatures Aged building Page 7

10 Kindergarten in Khovd: Picture from thermal (IR) camera before renovation. Picture from the renovation and insulation of the Kindergarten. Page 10

11 The kindergarten before the refurbishment. Page 11

12 This is not a very inviting environment for a 4-year old girl. Urinary infections are probably rather common. Page 12

13 The renovation included: Ceilings and roofs Walls Windows Doors Floors Page 13

14 There was a very clear division between female and male tasks. 58 windows were changed to 2-glass vacuum type. Most of the materials were produced locally. Page 14

15 The task to instruct how to get a right angle could be a challenge. Page 15

16 And how to use a label also needed thorough and hands-on instructions. Page 16

17 The principle for the wall insulation method. Page 17

18 Cooperation with the TVET project provided training of the staff of the construction companies involved. The students got a certificate for their participation in the training and practical work. Page 18

21 The radiators were more or less completely clogged. Page 21

22 Monitoring of indoor temperature outdoor temperature incoming heating water outgoing heating water total energy amount provide valuable facts for evaluation. Page 22

23 Outdoor signboards have increased the interests in Energy Efficiency and what the project is doing. Page 23

24 Showing that the indoor temperatures are still high during very cold periods are hard facts to prove that insulation is efficient. Page 24

25 Energy Efficiency Certificate for the Kindergarten in Khovd to be renovated (draft). The target was to improve the standard (energy consumption / m 2 and year) from E to B. Around 50% reduction of energy consumption is reached. Page 25

26 Some examples of temperature measurements from insulated and not insulated kindergartens in Khovd and Zavkhan. Page 26

34 26.00 Khovd Kindergarten #5 Insulated Temp indoors Why are five days in a row warmer than the two remaining? Why are there two peaks during some days?

35 Khovd Kindergarten #5 Insulated Temp indoors In a well insulated building even small additions of heat will have an impact in this case the heat supply from 200 children and staff is producing kw. The Monday Friday patterns are very different from the weekend patterns.

36 Khovd Kindergarten #5 Insulated Temp indoors The breakfasts and lunches are prepared in the kitchen and eaten in the rooms which adds additional heat to the rooms during two significant periods every day.

37 What are the Energy Efficiency results so far? Manual regulation of the radiators do not make use of the full saving potential. Thermostats need to be installed in the radiators. Practically, the indoor temperatures are regulated by opening the windows. A system for regulating the incoming water temperature (energy) is needed. Probably this system needs to be automatic. Monitoring locations and techniques must be chosen to avoid being influenced by non-relevant parameters. The special applications to estimate the energy consumption needed before and after renovation indicates energy savings of 50%! Page 37

39 Technical support through equipment Page 39

40 The thermographic measurement camera provides images to assess and monitor the energy leakages in buildings. The more yellow the more leakages and money losses. Page 40

41 Environmental air pollution aspects Page 41

42 Ineffective heating systems also cause heavy air pollution problems through the large amount of smoke from chimneys. Pictures from Khovd in January Page 42

43 The meteorological conditions during winter cause so called inversions. That means that a lid is established in the atmosphere at an altitude of meters which effectively blocks the air pollution from dispersing. Page 43

44 The smoke from the high chimney to the right is seen moving in the weak wind to the left but under the inversion layer. Page 44

45 The smoke from the large amounts of low chimneys add to the air pollution levels. All smoke accumulates under the inversion. Page 45

46 From a distance it is easy to see and imagine the unhealthy pollution levels. A qualified estimate without instruments places the level of particular matters (PM10) at 1,000 µg/m 3 or more. The World Health Organization (WHO) limit is 40 µg/m 3. Page 46

47 Matching funds arrangements Page 47

48 In addition to the two already refurbished kindergartens in Khovd and Zavkhan, the project will renovate and insulate * a dormitory in Tes, * a school in Zavkhanmandal, * a clinic in Erdenekhairkhan soum, * a health center in Duut soum, and * school # 2 in Jargalant soum, under the Matching Fund arrangement during The choice of buildings has been made based on a number of criteria. Page 48

49 The initial arrangements include a sharing between SDC/BMZ and the Mongolian side. Due to the troublesome financial situation for the Mongolian Government, the Local Development Funds (LDF) have been cut by 37% and more reductions could come. After discussions and adjustments, the average proportion is around The aimags have allocated a proportionally larger part of the reduced LDFs to the Matching Funds than to other projects. Page 49

72 In the following graphs, please note the difference how the incoming water temperatures vary with the performance of the stoker. The outgoing water temperatures vary with the incoming temperatures of course, but also with the effectiveness of the heating system (pipe lengths, flow rates, etc) Page 72

73 Zavkhan: Tes soum. School. NOT insulated. Temp indoors Temp outdoors Water in Water out The stoker performs rather well, but the quality of the heating system is very poor with low temperatures

74 0.00 Zavkhanmandal: School for 160 children. NOT insulated. Temp indoors Water in Temp outdoors Water out The stoker has a clear diurnal working schedule. With better performance the building would have been reasonably warm but the quality of the building is low.

75 70 Khovd: Duut soum. Health center. NOT insulated. Temp indoors Temp outdoors Water in Water out The stoker wakes up rater late every morning. The building s capacity to store heat is very low.

76 70.00 Khovd Jargalant: School Nr 2. NOT insulated. Temp indoors Temp outdoors Water in Water out The district heating system provides a rather steady supply. The usage of the heat is rather good, but the quality of the building is very poor.

77 Budget and tariff issues Page 77

78 You and we are spending large budgets on renovations but... the heat tariffs are flat (per area or volume)!!! reduced heat demands might encourage the heat supplier to reduce the amount of heat but still receive the same payment reduced heat costs might reduce the public building budget for next year Where is the incentive? Who benefits? Good Governance will provide better Energy Efficiency Page 78

79 Basic economic estimates based on standardized figures Costs for refurbishment of a kindergarten: 250,000,000 ( 120,000) The Government calculates 0% for internal loans for investments Depreciation time: 20 years Capital costs per year: 12,500,000 Page 79

80 Basic economic estimates based on standardized figures (Kindergarten #5 in Khovd for 2012) 350,000, ,000,000 [SERIES NAME] 300 M 250,000, ,000, ,000,000 Salaries 100,000,000 50,000,000 [SERIES NAME] 60 M = 20% Misc 0 Electricity Water Maintenance Total budget Page 80

81 Basic economic estimates based on standardized figures The conclusion is easy: It pays to renovate a public building Assumed heat savings are 50% = 30,000,000 ( 14,000) Compared to the capital costs for refurbishing = 12,500,000 ( 5,800) BUT The tariffs are flat so what is the purpose??? The pay-back calculations for the costs for renovation are heavily dependent on the financing arrangements and the tariff structure Page 81

82 Page 82

83 Balancing various costs (easy to estimate) vs other benefits (difficult to estimate) - Capital costs - Heating costs + Healthier children with higher quality of life + Less sickness (medication, hospital) costs + Less need for parents to stay at home nursing their sick children + Improved learning conditions will increase the assumed productivity long term + Improved environmental conditions through less coal burning? What is worth doing? Page 83

84 Conclusions Page 84

85 A well functioning heating system in a well insulated school, kindergarten, health centre, etc... Page 85

86 ... will make children and adults happy and healthy, and eager to learn for life and money will be saved, but the tariffs must be realistic! Page 86

87 Thank you and we look forward to informing you again about our project during the next NEXUS meeting. Page 87
