How Can Floor Covering Influence Buildings’ Demand Flexibility?

چکیده
Although the thermal mass of floors in buildings has been demonstrated to help shift cooling load, there is still a lack information about how floor covering can influence floor’s load shifting capability and buildings’ demand flexibility. To fill this gap, we estimated flexibility based on daily peak reduction for different configurations regions, using EnergyPlus simulations. As response strategy, used precooling global temperature adjustment. The result an adverse impact building’s Specifically, under same reductions were up 20–34% concrete whereas they only 17–29% carpet-covered floor. This because hinders convective coupling between surface zone air reduces radiative heat transfer surrounding environment. In hot climates such as Phoenix, almost negated yielded low wood floor, representing mass. Sensitivity analyses showed that covering’s effects be more profound with larger area, greater adjustment depth, or higher radiant gain. With effect ignored given building, its would overestimated, which could prevent grid operators from obtaining sufficient maintain grid. Our findings also imply efficient grid-interactive buildings, traditional standard design modified increasing renewable penetration.

Two-floor buildings need eight colors
Motivated by frequency assignment in office blocks, we study the chromatic number of the adjacency graph of a 3-dimensional parallelepiped arrangement. In the case each parallelepiped is within one floor, a direct application of the Four-Colour Theorem yields that the adjacency graph has chromatic number at most 8. We provide an example of such an arrangement needing exactly 8 colors. We also d...
متن کاملExamples of buildings constructed via covering spaces
The purpose of this note is to use covering space theory to construct new examples of buildings. On the level of Coxeter systems, this contsruction was described previously in Davis [4]. It goes as follows. Start with a Coxeter system (W ′, S). Change some m(s, t)’s in its Coxeter matrix from integers ≥ 2 to the symbol ∞ . This defines a new Coxeter system (W, S). Suppose C′ is a building of ty...
