A simple method to consider energy balance in the architectural design of residential buildings

Abstract

This paper describes a morpho-energetic study that is part of a broader study that considers the morphology of energy-saving cities. Nowadays, French urban planners recommend denser cities. Are dense and compact cities really sustainable? How can dwelling designs balance the environmental issues with the inhabitants' wishes? This study is focused on two urban typologies: the nanotours (little tower concepts made up of houses) and the refurbishment of 1960s-70s towers. In order to check the energy performance of these high-rise forms, this research proposes a simple method to consider an energy balance in the architectural design of buildings. In particular, this paper examines the link between the size of a building and its whole energy consumption (heating and cooling, lighting, hot water, building energy and the inhabitants' consumption). The input data is the primary energy consumed during both the construction and the use of a building. The output parameters are the dimension ranges (size) of an energy-saving building. In conclusion, the paper explains the prospects of this study and its possible implementation for energy-saving cities.
