Ibm Smarter Planet

Akita City is the prefectural capital and the center of politics, economics and transportation. The urban area consists of the city and the surrounding area with a population of 450,000. The Opportunity To comply with the Japanese Revised Energy Saving Law, Akita City is required to capture the energy consumption volume of all facilities owned by the city and to make precise notifications to the government. In addition, it is obliged to take efforts to reduce energy consumption by at least 1 percent every year, and is required to calculate and report the value on an annual basis. The city needed better visibility into, and a detailed understanding of, its energy usage to optimize investment plans, draft energy reduction targets based on timely collection of energy information, manage and operate overall facilities, and create reports required for relevant laws and regulations. What Makes It Smarter Akita City has implemented an integrated building management solution that collects, manages and analyzes energy data to help the city meet regulatory requirements. Real-time collection of building information via sensors allows the city to analyze trends and predict whether facilities are on track to meet their energy goals. Remedial measures can be taken quickly in cases where consumption trends are negative. Three-dimensional, color-coded, layered map displays can help the city quickly spot problem areas, which often cannot be readily seen from figures and graphical charts. The solution enables the city to manage electricity consumption proactively. For example, peaks in electricity use can be predicted and targets set so that automatic alerts are issued.
