Solution Overview

Problem

Existing energy management tools can only provide total electrical usage data from building meters, lacking specificity to diagnose energy usage issues effectively, limiting their usefulness in energy conservation efforts.

Innovation Solution

A software tool that converts energy usage data from building meters into detailed information by incorporating building characteristics, weather data, and device usage patterns, allowing for precise identification of energy consumption by devices and time, using a JAVA-based program that calculates energy usage by dividing the day into distinct periods and iteratively matching calculated loads to meter readings.

1Loss of information

If total electrical usage data is provided from building meters, then energy management information is available, but the data lacks specificity for effective diagnosis of energy usage issues

Engineering Contradiction:
Improveenergy usage information specificityVSAvoidsoftware processing complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent segments total electrical usage data into individual appliance-level consumption data by dividing the day into distinct periods (off-peak, mid-peak, on-peak) and using iterative calculations to attribute energy consumption to specific devices based on their operational patterns and characteristics

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The software acts as an intermediary that processes raw meter data through multiple calculation stages, using building characteristics, weather data, and device usage patterns as intermediate variables to transform aggregate energy data into appliance-specific consumption information
