ところで、ビルディング(以下「ビル」と略記する。)の管理を専門に行うビル管理会社等では複数のビル等の建物について管理を行っており、それぞれの建物について室内環境とエネルギー効率の最適化を図ることが行われている。この種の最適化のために、例えば特許文献1に記載されたエネルギー管理装置では、所定期間の目標値が設定され、この目標値と実績値とを照合した照合結果を月形式の累積グラフ等で表示させることが行われている。   By the way, building management companies that specialize in building management (hereinafter abbreviated as “buildings”) manage multiple buildings, etc., and optimize the indoor environment and energy efficiency for each building. Things are going on. For this type of optimization, for example, in the energy management apparatus described in Patent Document 1, a target value for a predetermined period is set, and a collation result obtained by collating the target value with the actual value is displayed in a monthly cumulative graph or the like.

Also, because the indoor environment differs depending on the location of the building, etc., building management companies that manage multiple buildings need to understand the indoor environment of each room for each individual building. . Then, based on the grasped data such as the indoor environment, the operation of the air-conditioning equipment and the lighting equipment for adjusting the indoor environment and energy efficiency is adjusted.

ビル管理会社等は、把握した室内環境やエネルギー効率の最適化を図るための空調設備等の運転調整について、建物の所有者に対して説明する。このとき、所有者の理解が容易となるような資料を必要とする。   The building management company, etc., explains to the owner of the building how to adjust the operation of the air conditioner and the like to optimize the grasped indoor environment and energy efficiency. At this time, it is necessary to have materials that make the owner's understanding easier.

そこで、この発明は、多くの建物にBEMSが導入されていることに着目して、このBEMSで得られる室内環境等の各種の計測データをもとにして、室内環境やエネルギー効率の最適化のための改善方法を把握しやすい建物の消費エネルギー削減のための外気冷房診断手法を提供することを目的としている。   Therefore, the present invention pays attention to the fact that BEMS is introduced in many buildings, and based on various measurement data such as the indoor environment obtained by this BEMS, the optimization of the indoor environment and energy efficiency. The purpose of this study is to provide an outside air cooling diagnostic method for reducing energy consumption in buildings that is easy to grasp for improvement.

If the air conditioning system corresponds to each room of the building, the cold energy consumption, temperature and humidity for the air conditioning system are the cold energy consumption, temperature and humidity in each room. Calculate the indoor enthalpy from the accumulated cold energy of the air-conditioning equipment collected in the current month and the indoor temperature and humidity to obtain the monthly average value, and the air conditioning system enthalpy- Plot the cold consumption. In addition, an outside air enthalpy line converted from the temperature and humidity of the outside air of the month is drawn on the air conditioned indoor enthalpy-cooling amount scatter diagram.
