Special Issue Information

Dear Colleagues,

You are aware of the global concern related to energy consumption in the built environment, as one of the major contributors to greenhouse gas emissions, responsible for climate change and its associated impacts. According to International Energy Agency statistics, buildings currently represent 30%–35% of the worlds’ total primary energy supply, 20%–25% of global CO2eq emissions, and about half of the world’s electricity consumption. If no action is taken to develop energy efficiency in buildings, energy need is predicted to augment by 50% in 2050.

A significant proportion of the energy consumption in buildings is used for cooling and heating applications. Therefore, a solution to achieve the goal of reducing energy consumption in buildings is to improve the energy performance of its envelope, which governs the heat exchanges between the outside and the indoor environment; and to promote renewable-energy-based HVAC systems. Along with building optimal orientation, this is the baseline of so-called net zero or net positive energy buildings approaches.

Thus, to further spread the technologies and methods related to energy-efficient buildings, this Special Issue, entitled “ Modeling of Heat and Mass Transfers in Building Innovative Envelopes and Systems ”, was proposed for the international journal Energies, which is an SSCI and SCIE journal (2017 IF = 2.707). This Special Issue mainly covers original research and studies related to the above-mentioned topics, including but not limited to smart energy materials for buildings, bio-based materials, super-insulating materials, phase change materials, envelope integrated energy systems, renewable-energy-assisted HVAC systems, building integrated photovoltaic/thermal (BIPV/T), and so on. Papers selected for this Special Issue are subject to a rigorous peer-review procedure with the aim of rapid and wide dissemination of research results, developments, and applications.

I am writing to invite you to submit your original work to this Special Issue. I am looking forward to receiving your outstanding research.

As the heating demands of buildings drop considerably, the use of solar walls makes increasing sense. One of the obstacles to the development of such walls is their need for on-site implementation by specialized companies. On the other hand, a storage wall is generally composed of heavy materials with high inertia, which prevents prefabrication of the solar component. To avoid this problem and allow for solar walls to be prefabricated in the factory, a novel approach to replacing this heavy wall with a lighter storage wall incorporating phase change materials (PCM) has been proposed. This paper aims to demonstrate the impact of PCM on the thermal energy performance once they have been integrated into the storage wall of the composite Trombe wall. Addressed herein will be the heat transfer exchange inside a house located in the northern part of France, where a composite Trombe wall has been fitted without PCM. Three configurations will be investigated—(1) the model house without the solar Trombe wall, defined as the reference configuration; (2) the model house integrating the concrete solar Trombe wall; and (3) the model house integrating the PCM solar Trombe wall. Two setpoint temperatures will be introduced—(a) a constant setpoint of 20 °C, and (b) a variable setpoint of 19 °C (14 h from 7:00 a.m. to 9:00 p.m.) and 16 °C (10 h from 9:00 p.m. to 7:00 a.m.). Furthermore, three different climate conditions will be adopted to run simulations—Paris-Orly, Lyon, and Nice. Dymola/Modelica, a dynamic thermal simulation tool, will be utilized to simulate the thermal performance of these defined configurations. The results obtained, regarding a solar Trombe wall installation that applies two distinct storage walls exposed to the weather of Paris, showed similar minimizations of the one-year energy heating demand inside the bedroom, equal to roughly 20% (i.e., 20.45% of concrete storage wall and 19.90% of PCM storage wall) compared to the reference configuration (i.e., the house with no solar Trombe wall). Based on the imposed setpoint temperature by means of night and day reductions, the resulting heating energy demand in the bedroom, through application of the two storage walls (concrete and PCM) and three different climatic regions could be minimized by 20.34% in Paris, 20.20% in Lyon, and 68.10% in Nice (for the concrete storage wall) vs. the reference configuration; and by 18.79% in Paris, 19.56% in Lyon, and 55.15% in Nice (for the PCM storage wall) vs. the reference configuration.
