Theoretical and numerical results for boundary feedback control of the Boussi- nesq Equations are discussed. The problem is motivated by design and control of en- ergy ecient building systems. In particular, new low energy concepts such as chilled beams and radiant heating lead to problems with Dirichlet, Neumann and Robin type boundary conditions. It is natural to consider control formulations that account for minimizing energy consumption and providing reasonable performance. We dis- cuss a LQR type control problem for this system with Robin/Neumann boundary control inputs. The feedback functional gains and the corresponding feedback laws provide insight into determining good spatial location of sensors for optimal opera- tion of energy ecient buildings. A 2D problem is presented to illustrate the ideas and demonstrate the computational algorithms.
