Brief Overview
BEAMS (Building Energy & Environment Advanced Management System) is a system to support facility operation and energy management, tallying and accumulating building facilities' point data.
BEAMS System Layout (+ centralized monitoring system)
Features
1) High universality /extensibility
2) Storage and accumulation of real-time information
3) Advanced technology of data extraction
4) Analogical supplement calculation/ reduction of introduction cost
■Introduction Method of BEAMS
Ａ）In case the centralized monitoring system is supplied by Alephnet
- Install data collecting PLC for BEAMS, and load data into BEAMS server through direct communication with centralized monitoring network.
- Data is retrievable every one minute.
B) In case centralized monitoring system is supplied by other system integrator
- BEAMS periodically retrieves the CSV file of operation data which was composed by centralized monitoring system and stored in a specific folder.
Function
＜Basic Service＞
- User Management (Pattern Definition 1/Pattern Definition 2 )
- Periodical Report (daily/monthly/yearly issue)
- Analysis Support (extraction of point data, control status confirmation, measuring speed conversion, trend graph, XY correlation, frequency distribution, set analysis, laminated bar/pie chart, different time & date point comparison
- Online Monitoring (online trend graph/online bar chart)
＜Optional Service＞
- Evaluation Chart Indication/E-mail Attachment (provide the evaluation report of energy-saving status referring to the collected and stored data in a system.)
- Data Extraction, Record, Output System [EcoBit]
- Alarm-E-mail Service (abnormal conditions are previously programmed installed, and when some of these conditions are detected, alarm e-mail is sent.)

In the Kusatsu-Biwa Lake Campus of Ritsumeikan University, since BEMS was introduced in 2003, facility operation data had been stored and accumulated. In 2006, using those data accumulated for three years, Alephnet gave the operation efficiency analysis of the major facilities. As a result, inefficient operations had been sorted out, and energy-saving measures were prepared.
The first step was to implement countermeasures against inefficient heat source system which had supplied cool/hot water to the air-conditioning systems in 10 building in the campus. The result was JPY11,895,332. cost reduction compared to the previous fiscal year (as against JPY16,000,000. investment amount). Customer has enjoyed large cost reduction.
