BEMS (Building Energy Management System)

Objective:
Opportunities enabled:
Country:
Japan
Maturity:

A system to realize energy conservation by visualization of energy consumed in buildings. Primary function of BEMS is optimization of air conditioning systems, which contributes to improved management of energy consumption of equipment / system / entire building, information and analysis of consumption trend, improved energy efficiency and energy conservation.

Organisation providing the technology:
Ministry of Economy, Trade and Industry
Endorsing entity:

Ministry of Economy, Trade and Industry.

Benefits:

Energy savings of 5 - 30% of primary energy consumed in the facilities concerned, compared with the case when BEMS is not introduced.Reduction of energy cost.

Differentiators:

Variety of system structure, variety of application and reliability specializing in building energy conservation.

Succes factors and requirements:

It is important to design energy management plans that are flexible yet tailored to characteristics of building and customer needs. Such plans need to be formulated for the entire facility (according to fuel), for each system, and for each equipment, and requires expert skills.

Investments required:

Highly variable according to scale and composition.

Timeframe:

Ca. 6 months (highly variable according to scale and composition).

Countries where implemented:
China
Indonesia
South Korea
Malaysia
Philippines
Singapore
Taiwan
Vietnam
