Due to the increasing energy consumption of buildings worldwide, an alternative to minimize it is the implementation of Zero Energy Buildings (ZEB). One solution to achieve them is the correct use of solar radiation absorption (ARS). Starting from thermoenergetic simulations for four Brazilian cities and the use of different absorbances in the walls and VIII ENSUS – Encontro de Sustentabilidade em Projeto – UNISUL – Palhoça – 12 a 14 de maio de 2020 roofs, consumption was obtained for conditioning the environments of a residential building. The percentage of consumption reduction for each of the proposed solutions was also calculated, when compared to the one with the highest consumption in each city. For locations where the predominant demand is for cooling, lower ARS is the best solution; where the main demand is for heating, higher ARS values lead to less consumption. Finally, the reduction in the area of photovoltaic panels resulting from each solution was estimated, this reduction being proportional to that of consumption and also dependent on the solar irradiation values of each location.
