Abstract: The process for constructing a three dimensional model of the living space or interior space of a house or building from a floor-plan drawing of the house or building using special imaginary “building blocks” that are scalable cuboids and/or scalable triangular prisms to completely fill in the living space or interior space detailed on a two-dimensional floor plan of the house or building to create the overall three-dimensional model of the living space or interior space. This invention is paired with other software programs, wherein this invention is first used to determine the surface area and description/type of each segment of the total exterior surface of the conditioned shell, living space, or interior space of the house or building, which is then entered into other software programs in order to determine the optimum size of HVAC system and/or the optimum size and structure of air ductwork or ducting and/or other energy modeling calculations.

Abstract: A tailgate food preparation assembly includes an assembly trailer; a main storage bin carried by the assembly trailer; a mobile storage bin carried by the assembly trailer adjacent to the main storage bin, the mobile storage bin having a pair of front frame corners; and a storage bin hinge pivotally connecting the mobile storage bin to the assembly trailer at one of the pair of front frame corners. The mobile storage bin may be positional between a forward, storage and transport position and a rearward, food preparation position.
