Description

The present invention relates to a building support system that outputs the performance and price of a building according to the customer's wishes.

In recent years, there has been an increasing interest in energy saving of heating and cooling in buildings, and house makers display the heat loss coefficient (Q value) as the performance related to energy saving of their own buildings. The heat loss coefficient is calculated by subtracting the "heat loss due to ventilation of the building" from the "total heat loss of each part of the floor, wall, and roof (or ceiling) of the building", and then calculating the "floor area of the building". It is divided by, and the smaller the number, the higher the heat insulation performance of the building.

However, it is difficult for the customer to understand the goodness of the building only by displaying the heat loss coefficient.Therefore, it is possible to understand the performance of the building by calculating the electricity rate for one month from the heat loss coefficient and presenting it to the customer. I tried to make it easier. The calculation method to calculate the electricity rate for one month from the heat loss coefficient is as follows. First, the heat loss coefficient, the "floor area of the building (square meter)", and the "temperature difference inside and outside the building" The amount of heat that escapes to the outside is calculated, and this is converted to the amount of heat that escapes to the outside in one month. Then, the amount of electricity used for one month is calculated from the amount of heat that escapes to the outside in one month, the "heat amount of the air conditioner", and the "heat conversion efficiency of the air conditioner". Monthly electricity charges (air conditioning costs) were calculated.

However, the above calculation method is premised on that the air conditioner is operated all day long, and there is a problem in that the calculated cooling and heating costs are higher than they actually are. On the other hand, by making a correction using the current heating and cooling costs of the customer and the performance of the air conditioners, there are some that can calculate the cooling and heating costs that are more realistic for the desired building (heat loss coefficient). (Patent Document 1). According to the technique of Patent Document 1, it is possible to more easily understand the performance of the building and to easily think of a lifestyle that matches with the fact that the cooling and heating cost (running cost) that is closer to reality is known.

However, in the technique like Patent Document 1, since the running cost is calculated based on the performance of the building to consider the lifestyle, the building (heat loss coefficient) must be determined first. , It was not possible to present the building (building performance) that matched the running cost and lifestyle desired by the customer.

The present invention focuses on a calculation method for calculating a building heating/cooling cost (running cost) from a heat loss coefficient, and calculates a heat loss coefficient from a running cost. By the way, the conventional calculation method for calculating the heating and cooling costs from the heat loss coefficient does not consider the influence of the sunlight due to the change of seasons, the influence of the internal heat generation of the building due to the change of temperature, and the like. Therefore, if the summer heating and cooling costs, which will have a large impact on them, are calculated from the heat loss coefficient of the building, a value that is significantly different from the actual cooling and heating costs will be calculated. The heat loss coefficient could not be calculated.

On the other hand, in the present invention, when calculating the heat loss coefficient, the desired experience room temperature in winter, the desired heating cost in winter, the average winter temperature in the building, the winter window solar radiation acquisition rate, the average winter sunshine duration, facing south Since the size of the window is used, it is possible to take into account the amount of heat from sunlight and internal heat generation, while using as a reference the winter season when the influence of sunlight and internal heat generation is small. In addition, since the number of people who are at home all the day and the outing time are used, it is possible to take into consideration the operating time (heat amount) of the air conditioning equipment in one day. From these facts, the amount of heat required to calculate the heat loss coefficient can be accurately grasped, and a more accurate heat loss coefficient can be calculated.

Therefore, according to the present invention, the desired building information (the desired building number, the eaves depth, the vacant space around the site, the orientation of the building, the size of the window facing south, the building site), and the lifestyle information (family Number of people, number of people staying at home all day, going out time, desired room temperature in winter, air conditioning equipment to be used), and running cost information (desired heating cost in winter), enter the lifestyle and running cost desired by the customer. Since the performance of the building (heat loss coefficient, average skin heat transmission coefficient) is output, the building to be built can be presented based on the running cost and lifestyle desired by the customer.

Also, as the performance of the building to be built, in addition to the heat loss coefficient (Q value), the average skin heat transfer coefficient (UA value) is also output, so by presenting two types of building performance indicators to the customer. On the other hand, the performance of the building to be built can be more easily understood.
