    Abstract

    The primary objective of this paper is to investigate whether is it possible to achieve a zero greenhouse gas emission residential building (ZEB) operating in humid subtropical climate. Sydney, Atlanta, Shanghai and New Delhi, recognised as main energy policymaker centres, were included in the scope of analysis as referential locations. Calculations of annual energy consumption, embodied emissions from production (A1-A3) and replacement (B4) of construction materials, as well as on-site renewable energy production were performed on the basic of mandatory energy standards, building performance simulations and generic, process based lifecycle data. All calculations were based on single-family building model with timber structure. All building’s thermal energy demands are provided by electrical air to water heat pump with a backup of the electric coil heater. Additionally, the roof-photovoltaic system is used purposely so as to reduce GHG emission from building operation and materials. The preliminary results of this study show that zero emission ambition levels of residential buildng are only possible in Syndey and Atlanta, where mandatory energy codes enforced high standards of building energy performance. The paper presents and discusses the results of environmental impact induced by model residential building in each of referential location of humid subtropical climate. Additionaly general adjustments of the building performance requirements that could enable higher ZEB ambitions are proposed.
