With the incorporation of Passiv Haus methodologies with-in the building culture, the movement towards zero energy housing, in our temperate maritime climate, has a clear design strategy. However, larger buildings, due to denser patterns of occupation, have more complex cooling, ventilation and day lighting issues. Typically, in the 20th Century, strategies to deal with these large building environmen-tal design issues have centred on energy intensive solutions such as air conditioning. However, from both an energy-in-use and internal com-fort perspective, other design strategies need to be investigated. In this regard, natural ventilation – to be effective in reducing energy in-use within a building – has to work in combination with heat load reduc-tion strategies, both internally and externally, and with the placement of thermal mass. The design of these three elements, an integral part of the architecture of the building, entails that there is an impact on built form. This research aims to qualify the architectural impact of natural ventilation strategies in near zero energy buildings and the de-velopment of a low energy aesthetic, in combination with the quantifi-cation of energy in-use reduction.
