Monthly balance based method versus transient whole building energy simulation for passive house design
Abstract
For the design of the so called passive houses a monthly balance based method, is used. This paper compares the balance based method of the Passive House Planning Package (PHPP) with the results of an easy to use whole building energy simulation software based on a simplified black-box model. The different calculation methods for all heat flows influencing the energy performance are compared. Shortcomings and advantages of the different methods are discussed. It is shown that both methods can produce similar results when transient effects are neglected. It can be concluded, that the time demand to set-up a complete calculation in each of the tools is approximately the same. The amount of information and possible improvement strategies regarding energy demand and comfort that can be achieved are higher with the transient simulation.
