The Passive House Planning Package (PHPP) is a design tool used primarily for modelling a building’s energy balance to meet Passive House standards. PHPP is used to model a Passive House building for the lowest possible heating/cooling demand. A successful design can be validated by balancing heat gains and losses — through the manipulation of the building envelope design, the building’s site orientation, and engineered air exchange.
Building to the highest standard reduces the environmental footprint in several ways:
As a home becomes more energy efficient, embodied energy becomes a larger percentage of the lifetime energy footprint of the home. Landmark Passivhaus homes are engineered to lower embodied energy usage by making concious, judicious choices about construction materials and building components; their sourcing and transportation; and the construction process itself.
