We shall discuss both a method based on the standard formulation as well as a method based on a penalty approach, which combine techniques developed in our previous work on parametrized saddle point problems with current reduced basis techniques for parabolic problems. The analysis then shows how time integration affects the development of reduced basis a posteriori error bounds as well as the construction of computationally efficient reduced basis approximation spaces.
