Description

本発明は建築物の性能管理システムに関し、とくに複数の空調設備を有する建築物のエネルギー効率に関する性能を管理するシステムに関する。 The present invention relates to a building performance management system, and more particularly to a system for managing performance related to energy efficiency of a building having a plurality of air conditioning facilities.

地球環境問題等を背景に、建築設計分野においてもエネルギーの効率的利用による環境負荷削減が重要な課題となっている。例えばオフィスビル・ホテル・病院・工場等の建築物において、省エネルギー効果の高い空調設備やコージェネレーションシステム・地域冷暖房の導入を進めると共に、エネルギー及び居住環境を効率的に管理するシステム（Building Energy & Environment Management System；以下、BEMSということがある。）を活用してエネルギー利用の合理化を図ることが求められている。BEMSとは建築物のエネルギー、居住環境、設備を包括的に管理するシステムであり、建築物内の居住環境の快適さを損なわない範囲内でエネルギー使用量の削減を図る省エネルギー制御機能等を含む。また、BEMS等を利用して建築物の省エネルギーに関する包括的なサービスを提供し、居住環境を損なうことなく省エネルギーを実現する事業（Energy Service Company；以下、ESCO ということがある。）の普及も進められている。 Against the backdrop of global environmental issues and the like, reducing the environmental burden through efficient use of energy is also an important issue in the architectural design field. For example, in buildings such as office buildings, hotels, hospitals, factories, etc., the introduction of air-conditioning equipment with high energy-saving effects, cogeneration systems, district cooling and heating, and a system that efficiently manages energy and living environment (Building Energy & Environment Management System (hereinafter referred to as BEMS) is required to rationalize energy use. BEMS is a system that comprehensively manages building energy, living environment, and facilities, and includes an energy-saving control function that reduces the amount of energy used within the range that does not impair the comfort of the living environment in the building. . In addition, BEMS will be used to provide comprehensive services related to energy conservation in buildings and promote the spread of energy service businesses (hereinafter sometimes referred to as ESCO) that do not impair the living environment. It has been.

例えば特許文献１は、建築物の総合的な省エネルギー管理を行なうESCO用のシステムとして、使用するエネルギー量（又はエネルギー価格）を低減させるように建築設備の運用状況を設定する運用プログラムと、その運用プログラムで運用される設備の運用状況の計測値を記憶する計測値記憶部と、設備の予め計画された運用状況を記憶する計画値記憶部とを備え、計画値記憶部と計測値記憶部の運用状況の差異を表示し又は差異の原因を解析する設備管理装置を提案している。運用状況の計画値と実際の運用時の計測値との差異原因を解析し、その原因が例えば外気温度の条件や使用エネルギー源の条件等に起因する場合は、それらの条件に応じて内部環境が不快とならない範囲で運用プログラムにより設備毎の運用をエネルギーが低減する方向に変更する（特許文献１の段落0039、0063参照）。また、差異原因が設備の磨耗劣化やハードウェア故障・保全不備等である場合は設備の保守センターに改修指令を送信することにより原因を除去し、差異原因がユーザーの不適切な操作・運用である場合はインターネット経由でのユーザー宛電子メール等を送信することによりユーザーの注意を喚起して原因を除去する。このような設備の運用変更、改修指令や電子メール等の送信によって所望の省エネルギー目標の達成を目指す。特許文献２及び３は、特許文献１と同様にインターネット等を用いて建築物の設備機器の異常情報（異常内容がコード化されたデータ等）や定期情報（検針情報、日報・月報等）を管理する装置又はシステムを開示する。 For example, Patent Document 1 describes an operation program for setting an operation status of a building facility so as to reduce the amount of energy (or energy price) to be used as an ESCO system that performs comprehensive energy saving management of a building, and its operation A measurement value storage unit that stores the measurement value of the operation status of the equipment operated by the program; and a plan value storage unit that stores the planned operation status of the facility in advance, the plan value storage unit and the measurement value storage unit We propose a facility management device that displays the difference in operational status or analyzes the cause of the difference. Analyze the cause of the difference between the planned value of the operation status and the measured value during actual operation. If the cause is caused by, for example, the outside air temperature condition or the energy source condition, the internal environment As long as the operation is not unpleasant, the operation program is changed so that the operation of each facility is reduced in energy (see paragraphs 0039 and 0063 of Patent Document 1). In addition, if the cause of the difference is equipment wear deterioration, hardware failure, maintenance deficiency, etc., the cause is eliminated by sending a repair instruction to the equipment maintenance center, and the cause of the difference is due to inappropriate operation / operation by the user. In some cases, the user is alerted by sending an e-mail addressed to the user via the Internet and the cause is eliminated. Aiming to achieve the desired energy-saving goal by changing the operation of such facilities, sending repair instructions, sending e-mails, etc. Patent Documents 2 and 3 use the Internet, etc., in the same way as Patent Document 1, to provide information on abnormalities (such as data in which abnormal contents are encoded) and periodic information (meter reading information, daily reports, monthly reports, etc.). An apparatus or system for management is disclosed.

また特許文献４は、地域熱源から熱媒体を建築物内部の冷暖房設備に導いて冷暖房を行なう地域冷暖房システムにおいて、建築物内部の居住環境をある程度維持しつつ熱媒体の使用量を削減して資源及び費用の無駄を省く二次側（建築物側）システムを提案している。例えば地域熱源から建築物内部に冷水を導いて冷房を行なう場合に、二次側システムの冷水使用量と空調設備による温度・湿度とを継続的に計測し、季節・時刻・天候・過去の実績等を考慮して計測値から二次側システムの将来の冷水使用量を予測し、冷水予測量が目標値（例えば、地域熱源の契約使用量等）より過大となるときは先ず建物内部への送風温度を上げて除湿量を下げ、次に建物内部への外気取入量を少なくし、更に過大であるときは建物内部の設定温度を上げることによりピーク時の負荷条件を緩和する。このように将来の熱媒体使用量を予測して負荷条件を緩和することによりエネルギーの効率的利用を図り、地域熱源の使用量及び使用料金の最小化を図る。特許文献５は、特許文献４と同様に将来の熱媒体使用量を予測して負荷を緩和する熱源デマンド制御方法を開示している。 Patent Document 4 discloses a district heating / cooling system in which a heating medium is guided from a district heat source to a cooling / heating facility inside a building for cooling / heating, reducing the amount of the heating medium used while maintaining the living environment inside the building to some extent. In addition, it proposes a secondary side (building side) system that saves money. For example, when cooling is conducted by introducing cold water from a local heat source into a building, the cold water usage of the secondary system and the temperature / humidity of the air conditioning equipment are continuously measured to determine the season, time, weather, and past performance. The future cold water usage of the secondary system is predicted from the measured values in consideration of the above, etc., and when the predicted cold water usage exceeds the target value (for example, contract usage of local heat sources) Increase the ventilation temperature to lower the dehumidification amount, then reduce the amount of outside air taken into the building, and if it is excessive, increase the set temperature inside the building to ease the peak load conditions. In this way, the future heat medium usage will be predicted and the load conditions will be eased, so that energy will be used efficiently, and the use of local heat sources and usage fees will be minimized. Patent Document 5 discloses a heat source demand control method that predicts a future heat medium usage amount and relaxes the load, similarly to Patent Document 4.

しかし、特許文献１の設備管理装置は、設備毎の運用の調整により建築物の総合的な省エネルギーを図るものの、運用の不具合ではなく設備の性能が過大である等の不具合によるエネルギーロスを発見し難い問題点がある。とくに空調設備は多段にわたるプロセスにより構成され、部分的にはブラックボックス化された複雑な制御が行なわれ、空調負荷が未知である場合も多いため、性能不足を避けるために過大な性能で設計される傾向がある。性能不足による設備の不具合は空調区画内の環境悪化等により比較的顕在化し易いのに対し、性能過大による設備の不具合は単にエネルギーロス等として結果が現れるだけなので発見が難しい。性能過大のような顕在化し難い設備の不具合を早期に発見できるシステムの開発が望まれている。 However, although the facility management apparatus of Patent Document 1 aims at comprehensive energy saving of buildings by adjusting the operation of each facility, it discovers energy loss due to malfunctions such as excessive performance of facilities rather than malfunctions of operation. There are difficult problems. In particular, air-conditioning equipment is composed of multi-stage processes, partly controlled in a black box, and the air-conditioning load is often unknown, so it is designed with excessive performance to avoid performance deficiencies. There is a tendency to. Equipment malfunctions due to performance deficiencies are relatively obvious due to environmental deterioration in the air-conditioning compartment, while equipment malfunctions due to excessive performance are difficult to find because they only show results as energy loss. It is desired to develop a system that can quickly detect defects in facilities that are difficult to be manifested, such as excessive performance.

また、特許文献２のシステムは、建築物の全体的な省エネルギー化を図る際に設備毎に最適な運用の切り替えを行なうことが難しい問題点がある。実際の建築物では内部に複数の空調区画を有し且つ空調空間毎に使い方が異なるので、ピーク時の負荷条件を全ての設備について画一的に調整するのではなく空調区画毎に適切に調整する必要がある。また、建築物は多数の設備・空調区画を有する複雑なシステムであり、最適な性能及び運用は建築物の経年変化、使い方の変化等によっても変化し得るので、このような複雑なシステムにおいてエネルギー及び居住環境を包括的に管理するためには、長期にわたり設備毎の効率的な性能及び運用を検証できるシステムが必要である。 In addition, the system of Patent Document 2 has a problem that it is difficult to switch the optimum operation for each facility when the overall energy saving of the building is achieved. In actual buildings, there are multiple air conditioning sections inside, and the usage is different for each air conditioning space, so the load conditions at peak times are not adjusted uniformly for all facilities but adjusted appropriately for each air conditioning section There is a need to. In addition, buildings are complex systems with a large number of facilities and air conditioning sections, and optimal performance and operation can change due to aging of buildings, changes in usage, etc. In order to comprehensively manage the living environment, a system that can verify the efficient performance and operation of each facility over a long period of time is necessary.

そこで本発明の目的は、健在化し難い設備や運用の不具合を発見できる建築物の性能管理システムを提供することにある。 SUMMARY OF THE INVENTION An object of the present invention is to provide a building performance management system that can find facilities and operational problems that are difficult to be alive.

And recording / recording means 22 for recording. Moreover, the use energy plan value predetermined for every heat-source equipment 5 or air-conditioning equipment 6 of each building 1, the load factor plan value predetermined for each component 9 of the air-conditioning equipment 6, and predetermined for every air-conditioning equipment 6 Plan value storage means 23 for storing set plan values of temperature and humidity is provided. Furthermore, it has comparison information creation means 30 for creating actual / plan comparison information for each of the equipments 5 and 6 based on the measured value recorded in the measurement / recording means 22 and the plan value stored in the plan value storage means 23. . The comparison information creation means 30 in the illustrated example is a creation means 31 that creates energy use results / plan comparison information for each heat source facility 5 or air conditioning facility 6 and load factor results for each component device 9a, 9b of each facility 5, 6. A creation means 32 for creating plan comparison information and a creation means 33 for creating temperature / humidity setting results / plan comparison information for each facility 6 are included.

比較情報作成手段30で作成する空調設備６別の実績・計画比較情報を、図３の空調設備６を参照して説明する。同図の空調設備６は空調区画８と空調監視装置13とに接続され、熱源駆動機器9aである冷水コイル42及び蒸気コイル43と、電源駆動機器9bである排気ファン41及び給気ファン44と、排気口45及び外気取入口46とを有する。排気ファン41により空調区画８（負荷）から吸い込んだ空気を冷水コイル42で冷却・除湿し、蒸気コイル43で再熱したのち、給気ファン44により空調区画８へ送風する。空調監視装置13には、エネルギー使用量計測器12で計測された冷水使用量、蒸気使用量及び電力使用量が入力されると共に、室内環境センサ47で計測した空調区画８の温度及び湿度、更にファン41、44の運転状況、コイル42、43の流量（バルブ開度）等を含む各構成機器9a、9bの負荷率（定格出力に対する負荷の比率）が入力される。空調監視装置13は中央監視装置10に接続され、入力された各計測値は中央監視装置10へ送られる。 The actual / plan comparison information for each air conditioner 6 created by the comparison information creating means 30 will be described with reference to the air conditioner 6 in FIG. The air-conditioning equipment 6 in the figure is connected to an air-conditioning section 8 and an air-conditioning monitoring device 13, and includes a cold water coil 42 and a steam coil 43, which are heat source driving devices 9a, and an exhaust fan 41 and an air supply fan 44, which are power source driving devices 9b. And an exhaust port 45 and an outside air inlet 46. The air sucked from the air conditioning section 8 (load) by the exhaust fan 41 is cooled and dehumidified by the cold water coil 42, reheated by the steam coil 43, and then blown to the air conditioning section 8 by the air supply fan 44. The air conditioning monitoring device 13 receives the cold water usage, the steam usage, and the power usage measured by the energy usage meter 12, and the temperature and humidity of the air conditioning section 8 measured by the indoor environment sensor 47. The load factor (ratio of load to the rated output) of each component device 9a, 9b including the operation status of the fans 41, 44, the flow rate (valve opening) of the coils 42, 43, etc. is input. The air conditioning monitoring device 13 is connected to the central monitoring device 10, and each input measurement value is sent to the central monitoring device 10.

エネルギー使用実績・計画比較情報作成手段31は、例えば図３の空調設備６の冷水及び蒸気の使用計測値をそれぞれ冷水及び蒸気の使用計画値と比較して空調設備６別のエネルギー使用実績・計画比較情報を作成する。図１０のグラフは特定の一日における空調設備６の冷水及び蒸気の使用計測値の一例を示し、空調設備６の稼動時間中（9時〜21時）は常に除湿再熱運転による冷水・蒸気同時使用の状況が発生していることを表している。使用計画値において冷水・蒸気の同時使用状況が常に発生することを想定していない場合は、同図の使用計測値と使用計画値との比較から空調設備６について「冷水・蒸気の同時使用状況の過剰発生」という比較情報が作成される。この比較情報から、冷却エネルギーロスという空調設備６の性能を検証し、例えば冷水コイルのバルブ開度制御の調整により空調設備６を最適化できることが分かる。また、比較情報作成手段31は建築物１内の空調設備６の各々について比較情報を作成するので、例えば複数の空調設備６の比較情報に同様のエネルギーロスが発生している場合は熱源装置５（図２参照）の性能を検証できる。 The energy usage record / plan comparison information creating means 31 compares the measured use values of the cold water and steam of the air conditioning equipment 6 shown in FIG. 3 with the planned use values of the cold water and steam, respectively, for example. Create comparison information. The graph of FIG. 10 shows an example of measured values of cold water and steam used in the air conditioning equipment 6 during a specific day. During the operation time of the air conditioning equipment 6 (from 9:00 to 21:00), the cold water / steam generated by the dehumidifying and reheating operation is always used. Indicates that a simultaneous use situation has occurred. If it is not assumed that the use situation of cold water / steam will always occur in the planned use value, it will be shown that the air conditioner 6 shows the simultaneous use situation of cold water / steam by comparing the measured use value and the planned use value in the figure. Comparison information is generated. From this comparison information, it is understood that the performance of the air conditioning equipment 6 called cooling energy loss can be verified, and the air conditioning equipment 6 can be optimized by adjusting the valve opening control of the cold water coil, for example. Moreover, since the comparison information preparation means 31 produces comparison information about each of the air conditioning equipment 6 in the building 1, for example, when the same energy loss has occurred in the comparison information of the plurality of air conditioning equipment 6, the heat source device 5 The performance of (see FIG. 2) can be verified.

また負荷率実績・計画比較情報作成手段32は、例えば図３のファン41、44やコイル42、43の負荷率計測値を負荷率計画値と比較して空調設備６別の負荷率実績・計画比較情報を作成する。図１１のグラフは特定の一日における給気ファン41の負荷率計測値の一例を示し、空調設備６の稼動時間中（9時〜21時）は常に給気ファン41が負荷率100％の状況であることを表している。負荷率計画値において給気ファン41の負荷率100％の状況の過剰発生を想定していない場合は、同図の負荷率計測値と負荷率計画値との比較から空調設備６について「給気ファン41が負荷率100％」という比較情報が作成される。この比較情報から、給気温度が高過ぎることに起因して給気ファンの負荷が増大しているという空調設備６の性能を検証し、例えば給気温度（冷水コイルでの冷却温度）の調整により空調設備６を最適化できることが分かる。また、比較情報において負荷率計測値が計画値に比べて常に低い場合は、空調設備６の性能の過大等を検証することができる。 Further, the load factor actual / plan comparison information creating means 32 compares the load factor measured values of the fans 41 and 44 and coils 42 and 43 in FIG. Create comparison information. The graph of FIG. 11 shows an example of the load factor measured value of the air supply fan 41 on a specific day, and the air supply fan 41 always has a load factor of 100% during the operation time of the air conditioning equipment 6 (9:00 to 21:00). It represents the situation. If the load factor planned value does not assume an excessive occurrence of the load factor of 100% of the air supply fan 41, the air conditioner 6 is referred to as “air supply” by comparing the load factor measured value and the load factor planned value in FIG. The comparison information that “the fan 41 has a load factor of 100%” is created. From this comparison information, the performance of the air conditioner 6 that the load of the supply fan is increased due to the supply air temperature being too high, for example, adjustment of the supply air temperature (cooling temperature in the cold water coil). It can be seen that the air conditioning equipment 6 can be optimized. Moreover, when the load factor measured value is always lower than the planned value in the comparison information, it is possible to verify that the performance of the air conditioning equipment 6 is excessive.

設定実績・計画比較情報作成手段33は、例えば図３の空調区画８の温度及び湿度の設定値の記録と設定計画値とを比較して空調設備６別の設定実績・計画比較情報を作成する。例えば同図の空調設備６は夏季23〜26℃、中間期22〜25℃、冬季21〜24℃の範囲での設定が設計上計画されているが、設定値の記録がこの範囲から逸脱している場合は「設定温度不良○○時間」という比較情報が作成される。この比較情報から、空調設備６が過剰な設定で運用されていることを検証し、運用により空調設備６を最適化できることが分かる。 The setting result / plan comparison information creation means 33 creates setting result / plan comparison information for each air conditioning equipment 6 by comparing, for example, a record of set values of temperature and humidity in the air conditioning section 8 of FIG. . For example, the air conditioner 6 in the figure is planned to be set in the range of 23-26 ° C in the summer, 22-25 ° C in the middle, and 21-24 ° C in the winter, but the record of the set value deviates from this range. If so, comparison information “setting temperature failure XX time” is created. From this comparison information, it can be seen that the air conditioner 6 can be optimized by verifying that the air conditioner 6 is operated with an excessive setting.

このように比較情報作成手段30で作成した比較情報により空調設備６毎の性能及び運用をある程度検証できるが、上述したように建物物１の空調設備６毎の最適な性能及び運用は様々な要因によって変化し得るので、長期にわたる性能及び運用の検証を通じて最適化することが必要である。図示例の建築物性能管理システム20は、建築物１全体へのエネルギー供給量の計測値を所定期間の当初から累積する累積値算出手段26を有し、所定期間のエネルギー供給量の累積値が当該所定期間について予め定めた建築物全体のエネルギー消費計画量の許容範囲を越えたときにエネルギー警報を空調設備６毎の比較情報と共に出力することにより、長期にわたる性能検証を可能としている。更に図示例のように、建築物１全体への経時的なエネルギー供給量から将来の特定時点までのエネルギー供給量の増加分を予測する予測値算出手段27を設けることにより、増加分予測値を加えた所定期間のエネルギー供給量の累積予測値が許容範囲を越えた場合にエネルギー警報を比較情報と共に出力することも可能である。 As described above, the performance and operation of each air conditioning equipment 6 can be verified to some extent by the comparison information created by the comparison information creating means 30. However, as described above, the optimum performance and operation of each air conditioning equipment 6 of the building 1 has various factors. It is necessary to optimize through long-term performance and operational verification. The building performance management system 20 in the illustrated example has cumulative value calculation means 26 that accumulates the measured value of the energy supply amount to the entire building 1 from the beginning of the predetermined period, and the cumulative value of the energy supply amount for the predetermined period is By outputting an energy warning together with comparison information for each air conditioner 6 when the predetermined energy consumption plan amount for the entire building exceeds a predetermined allowable range for a predetermined period, performance verification over a long period of time is possible. Further, as shown in the illustrated example, by providing a predicted value calculation means 27 for predicting an increase in energy supply from the energy supply over time to the entire building 1 to a specific point in the future, the predicted increase value can be calculated. It is also possible to output an energy warning together with the comparison information when the accumulated predicted value of the energy supply amount for a predetermined period exceeds the allowable range.

累積値算出手段26及び予測値算出手段27による建築物１の性能管理方法の流れ図の一例を図４に示す。先ずステップS001において、累積値算出手段26により、計測・記録手段22に記録された計測器11による建築物全体のエネルギー供給量計測値を任意の所定期間（例えば１日、１週間、１ヶ月等）の当初から累積し、エネルギー供給量累積値を算出する。エネルギー供給源３が複数ある場合は、供給源３の種類毎に累積値を算出することができる。所定期間の途中までの計測値しか記録されていない場合は、予測値算出手段27により将来の建築物全体のエネルギー供給量の増加分を予測し（ステップS002）、エネルギー供給量累積値と増加分予測値とを加算することにより所定期間のエネルギー供給累積予測値を算出する（ステップS003）。予測値算出手段27は、特許文献４及び５と同様に季節・時刻・天候・予測直前までの実績（例えば、エネルギー供給量の平均値や変化勾配等）、過去の実績（例えば前年同月又は同日のエネルギー供給量等）を考慮して将来のエネルギー供給量を予測するか、必要に応じて従来技術に属する適当な数学的モデル等を用いて将来のエネルギー供給量を予測することができる。 An example of a flowchart of the performance management method for the building 1 by the cumulative value calculation means 26 and the predicted value calculation means 27 is shown in FIG. First, in step S001, the accumulated value calculation means 26 calculates the energy supply amount measurement value of the entire building by the measuring instrument 11 recorded in the measurement / recording means 22 for an arbitrary predetermined period (for example, 1 day, 1 week, 1 month, etc.). ) To calculate the cumulative energy supply. When there are a plurality of energy supply sources 3, the cumulative value can be calculated for each type of the supply source 3. When only the measured values up to the middle of the predetermined period are recorded, the predicted value calculation means 27 predicts the future increase in the energy supply of the entire building (step S002), and the accumulated energy supply amount and the increase By adding the predicted value, an accumulated energy supply predicted value for a predetermined period is calculated (step S003). As with Patent Documents 4 and 5, the predicted value calculating means 27 is the season, time, weather, results up to immediately before the prediction (for example, average value of energy supply, change gradient, etc.), past results (for example, the same month or the same day of the previous year). The future energy supply amount can be predicted using an appropriate mathematical model or the like belonging to the prior art as needed.

図４のステップS004〜S010は、警報出力手段28による処理を示す。ステップS004において計画値記憶手段23に記憶された建築物全体のエネルギー消費計画量を取り込み、ステップS005において所定期間のエネルギー供給累積値又は予測値とエネルギー消費計画量とを比較する。ステップS006において累積値又は予測値が消費計画量の許容範囲内にあるか否かを判断し、許容範囲を越えたときはステップS007〜S009において上述した比較情報作成手段30により空調設備６別のエネルギー使用実績・計画比較情報、負荷率実績・計画比較情報、及び／又は設定実績・計画比較情報を作成し、ステップS010において作成した比較情報をエネルギー警報と共に出力する。 Steps S004 to S010 in FIG. 4 show processing by the alarm output means 28. In step S004, the energy consumption plan amount of the entire building stored in the plan value storage means 23 is fetched, and in step S005, the energy supply cumulative value or predicted value for a predetermined period is compared with the energy consumption plan amount. In step S006, it is determined whether or not the accumulated value or the predicted value is within the allowable range of the planned consumption amount. If it exceeds the allowable range, the above-described comparison information generating means 30 determines whether the cumulative value or the predicted value is within the allowable range of the consumption plan amount in steps S007 to S009. Energy use results / plan comparison information, load factor results / plan comparison information, and / or setting results / plan comparison information are created, and the comparison information created in step S010 is output together with an energy alarm.

図７（Ａ）は、建築物全体の年間のエネルギー供給量累積値を月別に表したグラフの一例を示す。例えば累積値算出手段26により毎月末に年初から当月までのエネルギー供給量を累積し、予測値算出手段27により翌月のエネルギー供給量予測値を算出する。エネルギー供給量の累積値と予測値との合計が、翌月のエネルギー供給量予測値（年間計画値）を越える場合に、警報出力手段28によりエネルギー警報を空調設備別の比較情報と共に通信手段21及びネットワーク15経由で警報対象の建築物１の中央監視装置10、その建築物１の経営者16や管理者17等へ出力する（図１参照）。エネルギー警報を受け取った建築物１の管理者17等は、空調設備６別の比較情報を参照することにより警報出力時点における空調設備６毎の性能及び運用を検証すると共に、必要に応じて計画値との相違が大きい空調設備６の性能及び運用を見直す等の省エネルギー対策を採ることができる。 FIG. 7 (A) shows an example of a graph showing the accumulated energy supply amount of the entire building for each month. For example, the accumulated value calculating means 26 accumulates the energy supply amount from the beginning of the year to the current month at the end of each month, and the predicted value calculating means 27 calculates the predicted energy supply amount for the next month. When the sum of the accumulated energy supply amount and the predicted value exceeds the predicted energy supply amount for the next month (annual plan value), the alarm output means 28 sends an energy alarm together with the comparison information for each air conditioning facility 21 and the communication means 21 and Via the network 15, the alarm is output to the central monitoring device 10 of the building 1 and the manager 16 and manager 17 of the building 1 (see FIG. 1). The manager 17 of the building 1 who received the energy warning verifies the performance and operation of each air conditioning equipment 6 at the time of the alarm output by referring to the comparison information for each air conditioning equipment 6, and the planned value as necessary. It is possible to take energy-saving measures such as reviewing the performance and operation of the air conditioning equipment 6 that are significantly different from each other.

図７（Ｂ）は、エネルギー又は熱管理指定工場等において、工場全体の使用電力量又は熱量を法定値以下に抑える場合に本発明を適用した例を示す。この例では、累積値算出手段26により月毎に使用電力量又は熱量を累積し、必要に応じて原油換算量に換算する。また、予測値算出手段27により翌月の使用電力量又は熱量を予測し、必要に応じて原油換算量に換算する。累積値と予測値との合計がエネルギー又は熱管理指定工場について定められた法定値を越える場合に、警報出力手段28によってエネルギー警報を比較情報と共に出力する。 FIG. 7B shows an example in which the present invention is applied to a case where the power consumption or heat amount of the entire factory is suppressed to a legal value or less in a factory designated for energy or heat management. In this example, the accumulated value calculation means 26 accumulates the amount of electric power used or the amount of heat every month, and converts it into a crude oil equivalent if necessary. Further, the predicted value calculation means 27 predicts the amount of power used or the amount of heat for the next month, and converts it to a crude oil equivalent if necessary. When the sum of the accumulated value and the predicted value exceeds the legal value determined for the energy or heat management designated factory, the alarm output means 28 outputs an energy alarm together with the comparison information.

また図７（Ｃ）は、建築物全体の電力供給源又は地域熱源からのエネルギー供給量を契約最大値以下に抑える場合に本発明を適用した例を示す。この例では、累積値算出手段26により所定時刻毎に使用エネルギー量を累積し、予測値算出手段27により当日の使用エネルギー量のピークを予測し、ピーク予測値が契約最大値を越える場合に警報出力手段28によってエネルギー警報をする。図７（Ｄ）は、電力供給源又は地域熱源からのエネルギー供給量が契約値を大幅に下回っている場合に本発明を適用した例である。この例では、累積値算出手段26により日毎の使用エネルギー量を累積し、所定期間（例えば１週間又は１ヶ月等）にわたり日毎の累積値が許容範囲（例えば契約値に対して10％減の範囲）を越えて下回っている場合に、警報出力手段28によってエネルギー警報を出力する。 FIG. 7C shows an example in which the present invention is applied when the amount of energy supplied from the power supply source or the regional heat source of the entire building is kept below the contract maximum value. In this example, the accumulated energy calculation means 26 accumulates the amount of energy used every predetermined time, the predicted value calculation means 27 predicts the peak of the energy consumption amount for the day, and an alarm is given if the predicted peak value exceeds the contract maximum value. The output means 28 gives an energy alarm. FIG. 7D is an example in which the present invention is applied when the energy supply amount from the power supply source or the district heat source is significantly lower than the contract value. In this example, the accumulated energy calculation means 26 accumulates the amount of energy used every day, and the accumulated value for each day over a predetermined period (for example, one week or one month) is within an allowable range (for example, a range where the contract value is reduced by 10%). ), An energy alarm is output by the alarm output means 28.

本発明は、建築物全体の様々なエネルギー効率低下をエネルギー警報として把握できると共に、その警報発生時点における設備別の実績・計画比較情報を併せて出力するので、空調設備の性能及び運用の検証に有効に利用できる。また、設備別のエネルギー使用実績・計画比較情報、負荷率実績・計画比較情報、設定実績・計画比較情報に基づき設備毎の性能及び運用を見直すことにより、設備毎の性能及び運用の最適化を図ることができる。とくに設備の構成装置別の負荷率実績・計画比較情報に基づき、健在化し難しい設備の性能過大のような不具合を早期に発見することが期待できる。 The present invention can grasp various energy efficiency declines of the entire building as an energy alarm, and also outputs the results and plan comparison information for each facility at the time of the alarm occurrence, so that the performance and operation of the air conditioning equipment can be verified. It can be used effectively. In addition, by optimizing the performance and operation of each facility based on the energy usage results / plan comparison information, load factor results / plan comparison information, setting results / plan comparison information for each facility, the performance and operation of each facility can be optimized. Can be planned. In particular, based on the load factor results and plan comparison information for each equipment component of the equipment, it can be expected that defects such as excessive performance of the equipment that are alive and difficult will be discovered early.

こうして本発明の目的である「健在化し難い設備又は運用の不具合を発見できる建築物の性能管理システム」の提供を達成することができる。 In this way, it is possible to achieve the object of the present invention, which is “a building performance management system capable of finding malfunctions in facilities or operations that are difficult to be alive”.

上述した累積値算出手段26及び予測値算出手段27に加えて、図１の建築物性能管理システム20は、建築物１内の熱源設備９（図２参照）の使用エネルギー計測値の総計に対する二次空調設備６の使用エネルギー計測値の総計の割合として建築物１の全体の空調成績係数（以下、空調システムCOPということがある。）を算出する成績係数算出手段24を有する。成績係数算出手段24による建築物１の性能管理方法の流れ図の一例を図６に示す。ステップS201〜S202において、成績係数算出手段24に所定期間内の熱源設備９及び二次空調設備６の使用エネルギー計測値を入力し、ステップS203において所定期間内の空調システムCOPを算出する。二次空調設備６の使用エネルギーが熱量計等で計量されていない場合は、空調設備６の設計値又は運転時間等の指標値から使用エネルギーを推定し、その推定値を用いて空調システムCOPを算出することができる。 In addition to the cumulative value calculation means 26 and the predicted value calculation means 27 described above, the building performance management system 20 shown in FIG. 1 uses two values for the total measured energy consumption of the heat source facility 9 (see FIG. 2) in the building 1. A coefficient of performance calculation means 24 is provided for calculating an overall air conditioning performance coefficient of the building 1 (hereinafter also referred to as an air conditioning system COP) as a percentage of the total measured energy consumption of the next air conditioning equipment 6. An example of a flowchart of the performance management method for the building 1 by the coefficient of performance calculation means 24 is shown in FIG. In steps S201 to S202, measured energy values of the heat source facility 9 and the secondary air conditioning facility 6 within a predetermined period are input to the coefficient of performance calculation means 24, and the air conditioning system COP within the predetermined period is calculated in step S203. If the energy used by the secondary air conditioning equipment 6 is not measured with a calorimeter, etc., the energy used is estimated from an index value such as the design value or operating time of the air conditioning equipment 6, and the air conditioning system COP is set using the estimated value. Can be calculated.

図８は、所定期間内の空調システムCOPを表したグラフの一例を示す。同図（Ｂ）は所定期間の日毎の空調システムCOPの変化を表し、同図（Ａ）は所定期間内の空調システムCOPの平均値を表す。図６のステップS204〜S205において、警報作成手段28により、例えば予め定めた空調システムCOPの設定値とステップ203で算出した空調システムCOPとを比較して許容範囲内であるか否かを判断し、空調システムCOPが許容範囲を越えたときはステップS206〜S208において比較情報作成手段30により空調設備６別のエネルギー使用実績・計画比較情報、負荷率実績・計画比較情報、及び／又は設定実績・計画比較情報を作成し、ステップS209において作成した比較情報をエネルギー警報と共に出力する。空調システムCOPが許容範囲を越えた場合は熱源設備５又は空調設備６の性能又は運用の不具合である疑いが強いと考えられるので、空調システムCOPの異常をエネルギー警報として把握すると共に設備別の実績・計画比較情報を併せて出力することにより、空調設備の性能及び運用の検証に有効に利用できる。 FIG. 8 shows an example of a graph representing the air conditioning system COP within a predetermined period. FIG. 5B shows the change of the air conditioning system COP for each day in the predetermined period, and FIG. 6A shows the average value of the air conditioning system COP in the predetermined period. In steps S204 to S205 in FIG. 6, the alarm creating means 28 compares, for example, a predetermined set value of the air conditioning system COP with the air conditioning system COP calculated in step 203 to determine whether it is within the allowable range. When the air conditioning system COP exceeds the permissible range, the energy use results / plan comparison information, the load factor results / plan comparison information, and / or the setting results / by the air conditioning equipment 6 by the comparison information creation means 30 in steps S206 to S208 Plan comparison information is created, and the comparison information created in step S209 is output together with an energy warning. If the air conditioning system COP exceeds the permissible range, it is highly likely that the heat source equipment 5 or the air conditioning equipment 6 is malfunctioning or operating. -By outputting the plan comparison information together, it can be used effectively to verify the performance and operation of air conditioning equipment.

また、図１の建築物性能管理システム20は、空調設備６毎に所定期間内の温度及び湿度の計測値が当該設備６について予め定めた温度及び湿度の適正範囲から逸脱した逸脱頻度を算出する逸脱頻度算出手段25を有する。逸脱頻度算出手段25による建築物１の性能管理方法の流れ図の一例を図５に示す。ステップS101において、所定期間（例えば１日、１週間、１ヶ月）内の空調設備６の制御結果である空調空間８（図３参照）の温度及び湿度の計測値を逸脱頻度算出手段25に入力し、ステップS102において空調設備６毎に予め定めた温度及び湿度の適正範囲を入力する。 In addition, the building performance management system 20 of FIG. 1 calculates the deviation frequency at which the measured values of the temperature and humidity within a predetermined period deviate from the appropriate temperature and humidity ranges predetermined for the equipment 6 for each air conditioning equipment 6. Deviation frequency calculation means 25 is provided. An example of a flow chart of the performance management method of the building 1 by the deviation frequency calculation means 25 is shown in FIG. In step S101, measured values of the temperature and humidity of the air-conditioned space 8 (see FIG. 3), which are the control results of the air-conditioning equipment 6 within a predetermined period (for example, 1 day, 1 week, 1 month), are input to the deviation frequency calculation means 25. In step S102, an appropriate range of temperature and humidity predetermined for each air conditioner 6 is input.

温度及び湿度の計測値及び適正範囲の一例を図９に示す。ステップS103において温度及び湿度の計測値が適正範囲から逸脱した逸脱頻度を算出し、ステップS104〜S105において算出した逸脱頻度が許容範囲内にあるか否かを判断する。逸脱頻度が許容範囲を越えたときはステップS106〜S108において比較情報作成手段30により空調設備６別のエネルギー使用実績・計画比較情報、負荷率実績・計画比較情報、及び／又は設定実績・計画比較情報を作成し、ステップS109において作成した比較情報をエネルギー警報と共に出力する。 An example of measured values and appropriate ranges of temperature and humidity is shown in FIG. In step S103, a deviation frequency at which the measured values of temperature and humidity deviate from the appropriate ranges is calculated, and it is determined whether or not the deviation frequency calculated in steps S104 to S105 is within an allowable range. When the deviation frequency exceeds the permissible range, the comparison information creating means 30 in steps S106 to S108 uses the actual energy usage / plan comparison information, the load factor actual / plan comparison information, and / or the set actual / plan comparison by the air conditioning equipment 6.
