Abstract: A group management apparatus is configured to manage a plurality of air conditioning facilities installed in a plurality of buildings as a plurality of groups. The group management apparatus includes an obtaining section configured to obtain operational data of the air conditioning facilities through a plurality of control units disposed in the buildings on a one-to-one basis, and an extracting section configured to extract one or more groups satisfying predetermined conditions from the groups based on a plurality of assessment perspectives. The control units are configured to control the air conditioning facilities within the buildings. A group management system includes the group management apparatus and the control units.

Abstract: An air conditioner managing apparatus includes a storage unit configured to accumulate operation data about numerous indoor units, a first screen generating unit, a second screen generating unit and a display switching unit. The first screen generating unit is configured to generate a first screen on which a plurality of the numerous indoor units with a problem can be visually verified based on the operation data. The second screen generating unit is configured to generate a second screen on which the operation data related to a specific one of the plurality of indoor units can be visually verified. The display switching unit is configured to switch to the second screen relating to the specific one of the plurality of indoor units when the specific one of the plurality of indoor units displayed on the first screen is selected and an input of a prescribed button is accepted.

Abstract: An intermediary device for air conditioning control is connected to an air conditioning interface for generating and outputting an operation/non-operation request signal to a heat source on the basis of a room temperature and a temperature setting. The intermediary device has a receiving unit, a temperature-setting estimating unit, and a transmitting unit. The receiving unit receives the operation/non-operation request signal as input. The temperature-setting estimating unit calculates an estimated value of the temperature setting on the basis of at least the operation/non-operation request signal. The transmitting unit transmits to air conditioners the estimated value calculated in the temperature-setting estimating unit.

Abstract: Discrimination of the condition of polygons is carried out by performing coordinate transformation from a view reference coordinate to a light source coordinate for each polygon. Then shadowing is carried out for every pixel of the polygon which is to be partially shaded. Also when multiple light sources exist, detection of the polygon is carried out by performing a coordinate transformation to each light source coordinate system for each polygon to be subjected to a shadowing operation. The detection includes detecting whether or not each polygon is the most light source side from among several polygons, thereafter intensity for display of each pixel is obtained based upon every detection result corresponding to each light source coordinate system.

Abstract: A polygon-filling apparatus discriminates whether the polygon marks off ony one continuous lot of each scanning line according to a number of maximal values and a number of minimal values in a direction perpendicular to a scanning line and which transforms polygons discriminated as marking off two or more continuous lots on each scanning line to obtain only polygons marking off one continuous lot of each scanning line. The apparatus detects other apexes from any apex of the obtained polygon corresponding to maximum and minimum coordinate values in a direction perpendicular to the scanning line and paints a predetermined region according to ridge data on the left and right sides of each scanning line. The ridge data are obtained by interpolation between data indicative of neighoring apexes chained from apexes having maximum and minimum values.
