“…The first assumes an energy inflation rate equal to the general inflation rate observed over the last two decades, 2% on a yearly basis. The second assumes a higher energy price growth rate, as reported by Lollini, Barozzi, Fasano, Meroni, and Zinzi (2006), namely 4.5% yearly, this being the average growth rate shown by natural gas price over the last twenty years (source: National Authority for electricity and gas 4 ). The third scenario outlines a mixed situation, considering that measures to improve energy efficiency aim to achieve the reduction of fuel consumption, and consequently lower prices.…”

“…The surface and orientation of building openings have a bearing on building energy demand (Lollini et al 2006;Manioglu and Yilmaz 2006). Albatici and Passerini (2011) found that there was a direct relation between south-oriented building façades and energy demand .…”

The use of efficient design parameters in the initial stages of the life cycle of a building project helps to reduce the final energy demand. This article presents research results on the relation between the morphology of a building and its energy efficiency. Three types of residential buildings are analyzed: the single-family detached house, semidetached house and multidwelling building. The cases studied modeled in EnergyPlus to obtain building energy consumption per useful built surface. Also considered is the energy produced, thanks to the installation of photovoltaic solar panels on the building roof and on 50 % of the south façade surface. The paper provides a method to obtain the curve that shows the difference between the energy demand of residential buildings for various uses (HVAC, lighting, etc.) and the energy generated by installed solar panels in the building. The results reveal that the single-family detached housing model is the less energy-efficient. In the case of multidwelling houses, the optimal building height is obtained to reduce building energy consumption depending on total useful built area. The results show that up to 25 % of multidwelling building energy demand can be satisfied by solar energy on the rooftop and the façade. The balance between the energy demand and energy production of the building highlights the dimensional parameters that define optimal building shape from an energy efficiency perspective. The results obtained can be usefully applied to estimate the optimal geometric characteristics for a building of the same total surface area, which maximally reduces the final energy demand.

“…A literature review of building envelope design can be found in [12]. Some authors optimised the thermo-physical properties [13,14] or insulation thickness [15][16][17][18][19] of the opaque envelope. Other researches studied optimal Window-to-Wall Ratio (WWR) configurations [20,21] or combined an optimisation of thermo-physical properties and WWR [12,[22][23][24][25].…”
