Description

【0001】
【産業上の利用分野】
この発明は、個別建物の性能情報提示装置に関し、例えば、各営業所において顧客の建築予定物件の性能情報を提示するのに利用される。
【0002】
【従来の技術】
建物商品を選ぶときには、建物の大きさ、外観、間取りといった目に見える要素の他、目に見えにくい建物商品の性能を表す情報を重要視することが多くなってきている。建物商品の性能を表す情報としては、耐震性、耐火性、遮音性、耐久性などがあるが、近年、建物の省エネルギー化や環境負荷に関心が高まっており、建物商品がどれだけ省エネルギー化に配慮しているかを示す情報を顧客に提示することが重要になってきている。建物の省エネルギー化を示す指標としては熱損失係数(Q値)や夏期日射取得係数(μ値)があるが、その値の提示だけでは顧客に分かりづらいため、暖房負荷や冷房負荷を予測算出して提示することが行われている。これら暖房負荷や冷房負荷を予測するためには、シミュレーションソフト(このようなシミュレーションソフトとしてSMASHと呼ばれるものがある)による計算が必要である。
【0003】
【発明が解決しようとする課題】
上記シミュレーションソフトを用いる場合、データ入力等に非常に手間がかかるため、顧客の邸毎に暖房負荷や冷房負荷を算出することは現実的ではない。すなわち、従来は、基本仕様建物が具備する建物要素の情報に基づいて上記シミュレーションを実行し、このシミュレーションによる暖房負荷や冷房負荷を提示するのみであり、上記基本仕様建物と多少異なる顧客の各邸(例えば窓の個数や配置等が多少異なるような個別建物)について素早く暖房負荷や冷房負荷を提示するようにしたものはなかった。
【0004】
この発明は、上記の事情に鑑み、顧客の各邸について素早く暖房負荷や冷房負荷を提示することができる個別建物の性能情報提示装置を提供することを目的とする。
【0005】
【課題を解決するための手段】

【0006】
上記構成においては、基本仕様建物について予め実行したシミュレーションの結果から導き出した熱損失係数−暖房負荷近似線情報を保持しており、この熱損失係数−暖房負荷近似線情報と個別建物の熱損失係数とに基づいて暖房負荷を予測するから、顧客の各邸について一々上記シミュレーションを実行することなしに素早く暖房負荷を提示することができる。
【0007】
また、この発明の個別建物の性能情報提示装置は、基本仕様建物が具備する建物要素の情報に基づいてシミュレーションを実行した結果から導き出した夏期日射取得係数−冷房負荷近似線情報を保持する近似線情報記憶手段と、個別建物が具備する建物要素の情報から夏期日射取得係数を算出する夏期日射取得係数算出手段と、算出された前記夏期日射取得係数と前記近似線情報とに基づいて冷房負荷を予測する冷房負荷予測手段と、前記冷房負荷を提示する提示手段と、を備えたことを特徴とする。
【0008】
上記の構成であれば、基本仕様建物について予め実行したシミュレーションの結果から導き出した夏期日射取得係数−冷房負荷近似線情報を保持しており、この夏期日射取得係数−冷房負荷近似線情報と個別建物の夏期日射取得係数とに基づいて冷房負荷を予測するから、顧客の各邸について一々上記シミュレーションを実行することなしに素早く冷房負荷を提示することができる。
【0009】
前記近似線情報は基本仕様が異なる建物商品ごとに保持されており、入力部から入力された建物商品特定情報に基づいて近似線情報を選択するように構成されているのがよい。
【0010】
ホストコンピュータから離れた箇所に設けられたコンピュータの画面上に個別建物が具備する建物要素の情報を入力する画面が構成され、この情報入力画面に入力された情報が通信ネットワークを介して前記ホストコンピュータに提供され、このホストコンピュータが前記情報を用いて暖房負荷又は冷房負荷の算出処理を行い、算出結果を通信ネットワークを介して前記コンピュータに提供するように構成されているのがよい。これによれば、例えば、各営業所に置かれるコンピュータにおいては、建物の性能把握に係わる情報処理のためのソフトウェアや各種データは不要であり、ブラウザソウトを持つだけでよいようにすることが可能になる。
【0011】
予測された暖房負荷又は冷房負荷に基づいて暖冷房費及び/又はCO2排出量を予測算出して提示するように構成されていてもよい。

[Industrial application fields]
The present invention relates to a performance information presentation device for an individual building, and is used, for example, to present performance information of a customer's planned building property at each sales office.
[0002]
[Prior art]
When selecting a building product, in addition to visible elements such as the size, appearance, and floor plan of the building, information that expresses the performance of the building product that is difficult to see is increasingly important. Information that indicates the performance of building products includes earthquake resistance, fire resistance, sound insulation, and durability. However, in recent years, there has been increasing interest in energy saving and environmental impact of buildings. It has become important to provide customers with information that shows consideration. There are heat loss coefficient (Q value) and summer solar radiation acquisition coefficient (μ value) as an index to show energy saving of buildings, but it is difficult for customers to understand only by presenting the value, so it predicts heating load and cooling load. To be presented. In order to predict these heating loads and cooling loads, calculation by simulation software (some simulation software is called SMASH) is required.
[0003]
[Problems to be solved by the invention]
When the above simulation software is used, it takes a lot of time to input data, and it is not realistic to calculate the heating load and cooling load for each customer residence. That is, conventionally, the simulation is executed based on the building element information of the basic specification building, and only the heating load and cooling load based on the simulation are presented. None (for example, individual buildings in which the number and arrangement of windows are somewhat different) presented a heating load or a cooling load quickly.
[0004]
This invention aims at providing the performance information presentation apparatus of the individual building which can present a heating load and a cooling load quickly about each residence of a customer in view of said situation.
[0005]
[Means for Solving the Problems]
In order to solve the above-described problem, the individual building performance information presentation apparatus according to the present invention has a heat loss coefficient-heating heating approximation line derived from a result of executing a simulation based on information on building elements included in a basic specification building. Based on the approximate line information storage means for holding information, the heat loss coefficient calculation means for calculating the heat loss coefficient from the information of the building elements included in the individual building, and the calculated heat loss coefficient and the approximate line information A heating load prediction unit for predicting a heating load and a presentation unit for presenting the heating load are provided.
[0006]
In the above configuration, the heat loss coefficient-heating load approximate line information derived from the result of the simulation executed in advance for the basic specification building is retained, and the heat loss coefficient-heating load approximate line information and the heat loss coefficient of the individual building are retained. Therefore, it is possible to quickly present the heating load without executing the simulation for each customer residence.
[0007]
Further, the performance information presentation device for an individual building according to the present invention is an approximate line that holds summer solar radiation acquisition coefficient-cooling load approximate line information derived from a result of executing a simulation based on information on building elements included in a basic specification building. Based on the information storage means, the summer solar radiation acquisition coefficient calculating means for calculating the summer solar radiation acquisition coefficient from the information of the building elements provided in the individual buildings, and the cooling load based on the calculated summer solar radiation acquisition coefficient and the approximate line information A cooling load prediction means for predicting and a presentation means for presenting the cooling load are provided.
[0008]
In the case of the above configuration, the summertime solar radiation acquisition coefficient-cooling load approximate line information derived from the result of the simulation executed in advance for the basic specification building is retained, and the summertime solar radiation acquisition coefficient-cooling load approximate line information and individual buildings are retained. Because the cooling load is predicted based on the summer solar radiation acquisition coefficient, it is possible to quickly present the cooling load without executing the above simulation for each customer residence.
[0009]
The approximate line information may be stored for each building product having a different basic specification, and may be configured to select approximate line information based on the building product specifying information input from the input unit.
[0010]
A screen for inputting information of building elements included in the individual building is configured on a computer screen provided at a location distant from the host computer, and the information input to the information input screen is transmitted to the host computer via a communication network. The host computer may be configured to perform a heating load or cooling load calculation process using the information and to provide the calculation result to the computer via a communication network. According to this, for example, a computer placed at each sales office does not require software or various data for information processing related to grasping the performance of a building, and can have only a browser software. become.
[0011]
The heating / cooling cost and / or the CO2 emission amount may be predicted and calculated based on the predicted heating load or cooling load.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

The performance information presentation device 10 of this embodiment includes an information storage unit 1, an individual building performance calculation unit 2, an input unit (keyboard, pointing device such as a mouse) 3, and an output unit (display, printer, etc.) 4. Composed. A data input screen is displayed on the output unit 4 which is a display, and a numerical value can be input to the data input screen by the input unit 3 including a keyboard and a mouse. The individual building performance calculation unit 2 performs display processing control of the data input screen in addition to performing individual building performance calculation. In FIG. 2B, the personal computer 12 forms the input unit 3 and the output unit 4, and the host computer 11 forms the information storage unit 1 and the individual building performance calculation unit 2. Both the personal computer 12 and the host computer 11 have a communication function, and communicate information through the network 13. In the network usage type in this embodiment, it is assumed that the personal computer 12 placed in the sales office and the host computer 11 placed in the headquarters are connected via an intranet.

Information processing related to performance grasping is performed, and information processing results are provided to the personal computer 12 via the network 13.
[0014]
The information storage unit 1 stores weather data, Q value (heat loss coefficient) -heating load approximate line information, and μ value (summer solar radiation acquisition coefficient) -cooling load approximate line information of each region. The weather data for each region is used to predict the amount of solar cell power generation and the amount of heat collected by a solar-powered hot water supply system based on the weather in the building area. The Q value-heating load approximate line information and the μ value-cooling load approximate line information are based on the graphs shown in FIGS. 2A and 2B, and Y (Y is a heating load or a cooling load). = AX (X is a Q value or μ value) + b is held in the form of a linear function.
[0015]
FIG. 2A shows a Q value-heating load approximate line graph. The Q value-heating load approximate line graph is a result of executing a simulation based on information on building elements included in a basic specification building (in this embodiment, a building having the product name ABC), that is, a plot (scatter diagram) in the figure. The approximate line calculation calculation is performed from the above. The simulation uses software called SMASH. The Q value-heating load approximate line graph is created for each next-generation energy-saving area category (all 6 categories). In the figure, graphs from the second region to the fifth region are shown, and the first region and the sixth region are omitted.
[0016]
The Q value is the value obtained by dividing the amount of heat escaping from the inside to the outside in one hour by the floor area when the temperature difference between the outside and inside of the building is 1 ° C. The smaller this value, the higher the insulation performance. It is shown. In order to calculate the Q value in an individual building, opening data and building dimension data of the individual building are necessary. These opening data and building dimension data can be input using the input unit 3. The opening data refers to the size and orientation of windows and the like, and the building dimension data refers to the area and orientation of the outer wall.
[0017]
FIG. 2B shows a μ value-cooling load approximate line graph. The μ value-cooling load approximate line graph is a result of executing a simulation based on information on building elements included in a basic specification building (in this embodiment, a building having the product name ABC), that is, a plot (scatter diagram) in the figure. The approximate line calculation calculation is performed from the above. The simulation uses software called SMASH. The μ value-cooling load approximate line graph is created for each next-generation energy-saving area category (all 6 categories). In the figure, graphs from the second region to the fifth region are shown, and the first region and the sixth region are omitted.
[0018]
The μ value is the period average value of the ratio of `` the amount of solar radiation actually acquired inside the building '' to `` the amount of solar radiation acquired assuming that there is no shielding by the building '', and the smaller this value, the shielding performance Is high. In order to calculate the μ value in an individual building, the opening data and building dimension data of the individual building input from the input unit 3 described above are used.
[0019]
The individual building performance calculation unit 2 calculates the Q value and the μ value in the individual building based on the opening data and building dimension data of the individual building. And the heating load is predicted based on the calculated Q value and the linear function that is the Q value-heating load approximation line held by the information storage unit 1, and the calculated μ value and the information storage unit 1 hold the The cooling load is predicted based on a linear function that is a μ value-cooling load approximation line.
[0020]
FIG. 3 is an explanatory diagram showing an example of a display screen in the output unit 4. In the menu frame on the left side of the screen, there are buttons labeled “building area data”, “layout selection”, “opening data”, and “building dimension data” as data entry items. Click one of these buttons. Then, the data input screen appears in the right frame of the screen. Also, in the menu frame, buttons labeled “Solar power generation”, “Solar thermal hot water supply system”, “Heat loss coefficient”, and “Total result” are prepared as calculation output items. When clicked, the calculation result appears in the right frame of the screen. This figure shows a screen when the “building site data” button of the data input item is clicked.

The area classification, floor method, and azimuth are used for calculating the Q value and μ value, and the total floor area is used for predicting the heating / cooling load from the calculated Q value and μ value.
[0022]
FIG. 4 is an explanatory diagram showing an example of a display screen in the output unit 4 and shows a screen when the “heat loss coefficient” button of the calculation item is clicked.
[0023]
When the “Heat loss coefficient” button is clicked, the Q value for each building, the reference value of the Q value (government standard, new energy saving standard, next generation energy saving standard), heating load graph, cooling load The graph, the heating / cooling cost, and the CO2 emission amount due to heating / cooling are displayed. The heating load is obtained by multiplying the heating load per floor area calculated from the individual Q value by the building total floor area, and the cooling load is multiplied by the cooling load per floor area calculated from the individual μ value by the building total floor area. Can be obtained. In the figure, the heating / cooling loads of individual buildings are shown in a bar graph in comparison with the government specifications and new energy saving specifications.
