1 SUMMARY: Energy efficiency director plan of Santiago de Compostela. (EESP) Objective The present report is to give a brief summary about the Energy Efficiency Sustainable Plan (EESP) developed for the city of Santiago de Compostela, in order to link the PLEEC project, where the city of Santiago is part as case study, with the mentioned action plan. Therefore this summary aims to serve as a guide about the current state of Santiago city and to value the possibility to introduce the main findings of PLEEC s work packages in the action plan in order to improve the sustainability and efficiency in the city. Background and Motive Currently, PLEEC project is running into the WP6, where all results from WP2, WP3, WP4 and WP5 will be integrated in the model of sustainable city planning and summary of the best recommendations which will be provided for the cities as Action Plan for the Energy-Smart City. At this moment the city of Santiago de Compostela has a first draft of its Energy Efficiency Sustainable Plan that still is in process to be approved by the government. Likely, the approval will be at the end of the current year. This Energy Efficiency Sustainable Action Plan was elaborated by the Galician Technological Institute. The elaboration started in 2013 and its scope tackles the current energy state, strategic lines to follow and possible measures for implementation. In this way, the findings from the PLEEC's previous work packages could be introduced in the EESP before to be approved, remaking the EESP under the PLEEC approach. A brief summary of the EESP can be seem below

2 ENERGY EFFICIENCY SUSTAINABLE PLAN (EESP) of Santiago de Compostela. The Energy efficiency director plan of Santiago de Compostela aims to achieve that the municipality be a reference in sustainable development, savings and efficient management of energy in the public sector. The EESP is addressed towards achievement a global goal through of four specific goals, such as: - Improvement the energy efficiency and sustainability in every activity at city level, as well as municipal, through the most sustainable and cost-effective solutions. - Establishing a savings culture (energy, hydro resources, waste management, etc) in the municipality, promoting the awareness from the decision makers and collaborators to the citizens. - Contributing to reach the goals and the National commitments through the actions to improve the energy efficiency, reduce the hydro-footprint, manage waste and/or improve the biodiversity. - Taking into account the sustainability in the urban planning-related decisions and construction, contributing to improve the quality of life and urban comfort in citizens as well as in visitors. Situation and referential diagnosis The current situation of the municipality energy issues can be summarized taking into account the data from 2013 and 2014 (partially). The analysed data concerns four important pillars in municipal energy consumption, such as; - Housing - Municipal sector - Transport - Enterprise sector In this sense the energy resources analysed are the following: - Electricity - Natural Gas - Diesel Automobile - Gasoline - Gas-oil for heating

3 These energy resources are consumed in different municipal services, such as; - Public lighting - Public schools - Municipal facilities - Municipal sport facilities - Facilities for the unit of civil protection - Garden department - Urban transport - Municipal automobiles - Social centres Taking into account these variables and the data facilitated by the city hall, a consumption breakdown can be done as follow: Picture 1: Percentage of consumption per energy resource Continuously, an economic balance should be done but taking into consideration that energy prizes are different depending of its resource. Picture 2: Economic balance per energy resource

4 And consequently, the consumption can be converted in CO 2 emissions as follow: Picture 2: Percentage of CO 2 emissions per energy resource On the other hand, a glance about the consumption in the different municipal services can be given: ENERGY CONSUMPTION The largest energy consumption corresponds to the transport, closely followed by the public lighting (*) ENERGY ECONOMY BALANCE Due to electricity prize, the largest economic waste corresponds to public lighting (*)

5 CO 2 EMISSIONS Due to the primary energy resources used, the largest emissions correspond to public lighting (*) (*) Transportation involves the whole urban and municipal transport, as well as for in parks and gardens. BREAKDOWN FOR CONSUMPTION ENERGY RESOURCE The consumption was analysed with data between September 2013 and August ELECTRICITY The electricity consumption represents the amount of ,32 /year NATURAL GAS The Natural Gas consumption represents the amount of ,59 /year

6 DIESEL AUTOMOTION The Diesel consumption represents the amount of ,45 /year GASOLINE The gasoline consumption represents an amount of ,02 /year GASOIL C ( For Heating) The Gasoil C consumption represents the amount of /year

7 BREAKDOWN FOR MUNICIPAL SERVICE The data above descripted are consumed in the following municipal services: PUBLIC LIGHTING This municipal service is composed (according data delivered by city Hall) for 579 command centres and lighting points, which can be broken down as follow: Command centres Type of regulation system Regulation and tele-managing 47 Tele-managing 23 Tele-managing 3-D 1 Regulation 51 Double level reactance 1 Tele-managing and regulation 3-D 18 Any type of regulation 438 Picture 9: Percentage of regulation systems Lighting points Typology High pressure sodium steam Mercury steam 5926 Fluorescents 382 PL 434 Mastercolour 2190 LED 32 Metallic Halogen 524 Dichroic 97 Quartz 22 Other 304

8 Picture 10: Percentage of light typology Currently, the municipality is carrying out energy audits in the public exterior lighting, in order to know its weakness points and take the most suitable measures to improve the performance. SCHOOLS The scope involves 34 buildings dedicated to education. In 2008 some deficiencies were detected, most of them related with lighting. Besides, some schools cannot reduce their consumption for the impossibility to be connected to the gas network. Picture 11: Energy waste in schools

9 MUNICIPAL FACILITIES This area involves facilities such as; municipal managing buildings (city hall known as Pazo de Raxoi), fire station, socio-culture centres Definitely, a total of 78 facilities. Picture 12: Energy waste in municipal facilities This consumption represents ,77 /year. 11 audits carried out in 2008 detected a 63,63 % of building had inefficiency lighting systems. GARDENS AND PARKS DEPARTMENT This department manages more than m2 of green areas in 283 different zones, reaching an economic spending of ,33 /año. Picture 13: Energy waste in garden and park department

10 MUNICIPAL SPORT FACILITIES It composed by 29 facilities account with an economic spending of ,01 /year. Picture 14: Energy waste in municipal sport facilities TRANSPORTATION The transportation in Santiago de Compostela is divided in three main consumers, such us; urban transport, municipal automobiles and the transport for garden and parks departments. Taking into account this breakdown, another can be done regarding the economic spending. As follow: Urban transport: , 45 /year Municipal automobiles: ,8 /year Picture 15: Energy waste in transportation per municipal section

11 GOALS AND STRATEGIC LINES The main energy related highlights in the city of Santiago de Compostela are posed to be achieved in The expectations can be described in the following scheme: CURRENT TOTAL CONSUMPTION kwh/yr SAVINGS PUBLIC LIGHTING kwh/yr. 5 % SCHOOLS kwh/yr. 2 % MUNICIPAL FACILITIES kwh/yr. 3 % MUNICIPAL SPORT FACILITIES kwh/yr. 1,5 % kwh/yr. TRANSPORTATION 5 % TARGET CONSUMPTION ,04 kwh/yr. To carry out those expectations, the following strategic lines (LA) have been established: LA1: Electric bill optimization. LA2: Efficiency in heating systems LA3: Use of efficient lighting technologies LA4: Change the energy use LA5: Increase the electric machinery efficiency LA6: Increased efficiency in the housing exterior walls LA7: Saving in water consumption LA8: Use of renewable energies LA9: Energy management LA10: Exterior lighting Each one of those strategic lines are broken down in action programs, and this in turn, in particular actions, as it can be seen in the following schemes: (See Annex for further definitions, due to the schemes are pictures, it was impossible translate the texts)

17 RELATION WITH PLEEC PROJECT Taking into consideration schemes above, another breakdown can be done in order to classify the measures of the strategic lines. The classification can be done according the short and medium term for its implementation. At the same time, all of them will be classified under the PLEEC s approach. In this sense, the following scheme is broken down considering how, and which, PLEEC s work packages can be useful to promote each measure. All measures as located over a background colour. In some cases the background can be defined for several colours, in these cases the measures located there are susceptible to adopt indications from different WPs. The classification of work packages corresponds with the following definition of colours. GREEN: BLUE: VIOLET: The measure can be under approach of WP3 The measure can be under approach of WP4 The measure can be under approach of WP5
