3 8 What is energy monitoring? 3 Energy monitoring is a methodology-based regular metering of energy consumption with correlation of energy use with the outside temperature (considering the product produced*). *The product produced stands for an internal microclimate (internal temperature, air quality, etc.). It shows how energy is consumed and identifies a potential for energy saving

4 Energy Saving Initiative in the Building Sector in Eastern Europe and Central Asia Seven reasons for energy monitoring What for is energy monitoring? 1. To register and assess energy consumption and costs. Energy consumption depends on energy quality and price. In many companies EM allows comparing consumption and costs; energy consumption is monitored in time. While exchanging this data, people in charge of managing energy consumption – personnel, dispatchers and others can analyze their actions and adjust them. 2. To eliminate energy problems arisen and mistakes in electricity bills. Continuous energy consumption monitoring helps recognize problems. A sudden inexplicable increase of consumption requires that the reasons are studied at the origin. It is also necessary to analyze mistakes in bills. 3. To justify priorities in capital investments. Identify which sites of the company have the highest energy consumption and study possibilities for modernization or other ways to manage energy consumption.

5 Energy Saving Initiative in the Building Sector in Eastern Europe and Central Asia What for is energy monitoring? 4. To assess success in implementation of the energy policy/programme, reporting. Do you save yourself? How do you compare your actual money savings resulting from modernization with savings predicted by the contractor? Without EM it is next to impossible to answer these questions. EM reports and charts are the tools for proofs. 5. To create conditions for energy management. EM will make it possible to have a qualitative registration of these savings. 6. A very accurate budget. EM provides for a historic review of costs, which will help you plan your future budget more realistically. 7. To provide your organization with a possibility to enjoy reduced energy prices at the electricity market. The electricity market is quickly changing thanks to reforms and a growing competition among suppliers. These changes take place in parallel to similar changes at the natural gas market, which was also deregulated, resulting in a considerable decrease of prices for consumers. In order to use the advantage of having lower prices, it is important for your organization to understand the price policy (please see the chapter Understanding energy suppliers bills) and know the electricity load profile. It implies the awareness of how much electricity your organization consumes during the parts of the day and seasons of the year.

8 Energy Saving Initiative in the Building Sector in Eastern Europe and Central Asia Conditions for creating energy management system in a city 1. The city authorities should give a priority to energy efficiency and energy saving for a long-term sustainable development as well as to the necessity of creating energy management system in the city. 2. Availability of consultative support. 3. Availability of computer equipment enabling to solve the problem of data collection and processing about consumption of energy resources at many public facilities at the initial stage.
