Description

TECHNICAL FIELD [0001] The present invention relates to a building energy efficiency and service evaluation system,

The present invention relates to a building energy efficiency and service evaluation system, and more specifically, it is possible to perform overall management based on projects of building energy efficiency and service projects, and to provide a series of technical proposals, diagnosis evaluations, And a method for processing the same.

Due to the recent economic development and expansion of urban functions, most new buildings are aimed at high-tech, high-rise, and large-sized buildings. The facilities of buildings emphasize the convenience of maintenance, And is consumed.

As a result, the energy saving problem in the building is recognized as a very important factor, and a lot of research is being carried out to reduce energy consumption of the building. However, the technology for energy saving is, for example, a system in which air conditioning, power, and illumination systems are separately constructed, and an energy management system is operated on the basis of these. In particular, many studies have been conducted to improve the energy management efficiency. For example, there are researches on the performance diagnosis of the air conditioning equipment, control and management technology, and analysis of the energy consumption situation supplied to the building based on the IT technology .

However, existing researches are research on energy management efficiency of the same kind of equipment, and it is a technology that can maximize the energy saving effect by comprehensively analyzing and managing the energy consumption of the air conditioning, power, There is a lack of development.

Until now, the information on the technology of the energy sector has only been partially used because there is no system for collecting related information or organizing the system. As a result, general users receive considerable difficulty in obtaining various information and necessary information at an early stage by receiving only partial information.

In recent years, in order to solve such a problem, a database is provided and an online service is provided through a computer network. However, in Korea, the construction of a specialized energy database is a rudimentary step, and accumulation of information is insufficient.

For example, there is no integrated system for building energy efficiency and service business such as ESCO (Energy Service Company) business. In Korea, only standard contract exists for fairness of business, Proposals, diagnosis, and verification.

In the case of overseas countries, DEER (Database for Energy Efficient Resources), BEP (Building Performance Database Analysis Tools), ODYSSEE (annual information service of European energy efficiency database), France MURE (Mesures d'Utilization Rationnelle de l'Energie), which is a measure for energy-efficient use of the building, and C-BOA, which can analyze 9 technologies as a tool for performance verification, SEP (Superior Energy Performance).

As a result, there are few technology analysis or statistical analysis of energy saving database, and it is hard to find a system to manage and analyze building energy efficiency project through a series of processes.

In addition, current building energy efficiency and service projects are not standardized in the process of contracting, diagnosis and verification, resulting in confusion for energy users and business operators, as well as lack of precise definition of business performance. Problems also arise in terms of distribution of energy saving effects.

In addition, the performance evaluation is centered on engineering calculation or utility bill without accurate standards, so there is a lack of correlation analysis and future evaluation of variables that affect energy use.
