Abstract: An apparatus for location-based management of construction is provided. The apparatus includes a first layer locations system generating one or more first locations where construction activities can be performed in parallel, such as different buildings. A second layer locations system generates one or more second layer locations where construction activities can be performed in parallel for one or more of the first locations, such as different rooms within each building. A third layer locations system generates third layer locations where construction activities can be performed in parallel for one or more of the second layer locations, such as installation of finish features in each room. A construction activity location system associates each of a plurality of construction activities, such as pouring floors, installing walls, or installing finish, with one of the first locations, the second locations, or the third locations.

Abstract: A building having window structures in exterior walls of the building. Each window structure has an exterior and an interior panel spaced from one another to define a plenum therebetween, with radiation absorbing blinds positioned in the plenum. The blinds absorb solar energy, and air from within the building is circulated through the plenum to absorb energy from the blinds. The heated air can be circulated through a heat exchange heat storage structure, and selectively discharged to the outside, circulated to another building portion, or recirculated into the same building portion. Control means are provided to combine outside air with the inside air being circulated to maintain proper temperature in the building within predetermined upper and lower temperature limits.
