# Water, energy and meter records — AI City Technologies Source: https://aicity.am/features/en/utilities Language: en Availability depends on the user’s role, enabled building services and compatible equipment. ## Water, energy and meter records https://aicity.am/features/en/utilities Hot and cold water, energy and other measured services, each tracked separately. ### Hot and cold water https://aicity.am/features/en/utilities#utilities-1 Hot and cold water are tracked separately, each with its own rate. Consumption is calculated from the difference between previous and current readings, and the property’s history shows both the volume used and the resulting charge. #### Separate hot-water and cold-water services and rates https://aicity.am/features/en/utilities#utilities-1-detail-1 Set separate hot- and cold-water rates so their consumption and charges remain distinct. #### Usage calculated from consecutive readings https://aicity.am/features/en/utilities#utilities-1-detail-2 The difference between readings shows the water used during the period and provides the basis for billing. #### Track cubic metres or litres, depending on the service https://aicity.am/features/en/utilities#utilities-1-detail-3 The service’s chosen unit is used throughout readings and calculations to keep volume figures consistent. #### Apartment usage and charge history https://aicity.am/features/en/utilities#utilities-1-detail-4 Compare a property’s consumption and charges across months to understand changes in water use. ### Practical meter management https://aicity.am/features/en/utilities#utilities-2 Staff can enter monthly meter readings in a table or import them from Excel after reviewing the data. Initial readings, meter replacements and resets are recorded so those changes are reflected correctly in consumption calculations. #### A monthly readings grid https://aicity.am/features/en/utilities#utilities-2-detail-1 Enter the month’s readings in one table and check the data for the relevant properties. #### Record starting readings https://aicity.am/features/en/utilities#utilities-2-detail-2 Record the starting reading so subsequent consumption is calculated from the correct baseline. #### Account for meter replacements and resets https://aicity.am/features/en/utilities#utilities-2-detail-3 Record a meter change so the new reading is not mistaken for a sudden drop in consumption. #### Import readings from Excel with a review step https://aicity.am/features/en/utilities#utilities-2-detail-4 Import a prepared readings spreadsheet and review its rows to reduce repeated manual data entry. ### Reading checks and recalculation https://aicity.am/features/en/utilities#utilities-3 Before billing, staff can identify meters with missing readings and consumption that changed sharply from the previous period. Zero consumption is distinguished from an unentered reading, and corrected data can be used to recalculate the affected period. #### A list of missing readings https://aicity.am/features/en/utilities#utilities-3-detail-1 Identify properties whose readings are still missing and complete them before continuing billing. #### Unusual increases or drops compared with previous usage https://aicity.am/features/en/utilities#utilities-3-detail-2 A sharp-change flag helps distinguish a real change in use from a possible entry error. #### Zero usage is distinguished from a missing reading https://aicity.am/features/en/utilities#utilities-3-detail-3 An entered zero is treated as a reading, while an absent reading remains an item to complete. #### Correct errors and recalculate the affected period https://aicity.am/features/en/utilities#utilities-3-detail-4 Apply a corrected reading to the appropriate month so the affected billing period is recalculated. #### Bill a reading entered later https://aicity.am/features/en/utilities#utilities-3-detail-5 If a reading was missing at billing time, calculate the omitted consumption for the relevant period once it is entered. #### Correct a meter assigned to the wrong apartment https://aicity.am/features/en/utilities#utilities-3-detail-6 Review a meter-reassignment correction and confirm it after checking its accounting impact. #### Review subsequent consumption https://aicity.am/features/en/utilities#utilities-3-detail-7 When correcting a past reading, the system accounts for dependent later differences and period restrictions. ### Energy, heating and cooling https://aicity.am/features/en/utilities#utilities-4 Manage electricity, gas, heating and cooling charges in the same workspace. Each service has its own unit and rate, with heating and cooling calculated by consumption or floor area as appropriate. #### Electricity and gas https://aicity.am/features/en/utilities#utilities-4-detail-1 Track electricity and gas as separate services with their own rates and consumption data. #### Heating by consumption or floor area https://aicity.am/features/en/utilities#utilities-4-detail-2 Choose heating charges based on consumption or serviced floor area according to the building’s arrangement. #### Cooling by consumption or floor area https://aicity.am/features/en/utilities#utilities-4-detail-3 Calculate cooling charges by the configured consumption or area basis, separately from other services. #### Each service has its own unit and rate https://aicity.am/features/en/utilities#utilities-4-detail-4 Give each service the appropriate unit and price so different types of consumption are calculated correctly. ### Meter imports with row-by-row checks https://aicity.am/features/en/utilities#utilities-import-review When importing monthly readings, see which rows are ready to apply and which require review. Corrections to existing readings follow a separate process. #### Distinguish new and existing readings https://aicity.am/features/en/utilities#utilities-import-review-detail-1 In the preview, distinguish new, previously recorded, already billed and invalid rows. #### Protect recorded readings https://aicity.am/features/en/utilities#utilities-import-review-detail-2 An import does not overwrite a previous reading; detected errors are corrected through the designated review process. #### A note attached to a reading https://aicity.am/features/en/utilities#utilities-import-review-detail-3 Add a work note, for example about a replacement meter or unusual usage, so the circumstances remain understandable later. #### Identify records in closed periods https://aicity.am/features/en/utilities#utilities-import-review-detail-4 During import, identify closed-period rows that cannot be changed through a normal upload.
