“…Finally, increasing the inlets' size progresses the airflow inside the building, which consequently reduces the operative temperatures. Sustainability 2020, 12 The implementation of DSS decreased the atrium average temperature by 3-4 °C. Figure 12 shows an example of the air movement, which is measured in kilograms per second (kg/s), and indoor temperature changes in degrees Celsius (°C), on the 21st of July at 2:00 pm, where the wind speed was 4.9 m/s with a south-east wind direction for: (a) the existing case, (b) the DSS with initial openings of 10%, and (c) the DSS with fully opened building windows scenario, respectively; these results were obtained from EDSL Tas.…”

“…Recently, atria have received popular acceptance in modern architecture, especially in deep-plan buildings for their aesthetical, environmental, and economic benefits [10][11][12][13]. However, the use of atria is not limited to the buildings themselves: they may expand to form an urban design by gathering different buildings within the urban context [14].…”

Atria are added to buildings for their aesthetical, environmental, and economic benefits; the appropriate atrium design can enhance an atrium’s thermal performance and the adjacent spaces’ temperatures. However, inappropriate design decisions cause thermal discomfort and consequently, higher energy consumption. Since the Mediterranean climate has diverse climatic conditions around the year, a central atrium with a top-lit skylight is recommended, but during the summer period it can cause overheating, and the insertion of shading elements shrinks the lighting performance: thus, the atrium skylight design is supposed to improve thermal comfort without affecting the lighting level. This study investigated the improvement of thermal performance in the atrium building by the implementation of a double-skin skylight (DSS) to enhance the atrium thermal performance without shading. The research conducted computer simulations with Environmental Design Solutions (EDSL) Tas software sequentially. The study prepared various design strategies, and different proposals were tested and compared in terms of indoor temperatures, with reference to American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE-55). The implementation of DSS achieved an average of 77% comfort in working hours around the year with different opening percentages according to the outdoor conditions. Moreover, results show that changing the DSS glazing materials did not affect the thermal performance of the atrium.

“…A study investigating atrium energy consumption found that the atrium's space in a five-story building in Santiago had more than 75% savings in its cooling energy consumption, which is also known to be affected by the building's function, atrium type and type of glass [40,41]. The atrium building typology has a heating average in the winter season which is higher than that in the courtyard typology.…”

This paper aims to determine the optimal single-story office building model with a corner atrium regarding different atrium orientations and office-building window-opening ratios in the Mediterranean climate via EDSL Tas software. When window-opening ratios were 25% and 50% at the northeast and southeast orientations of atriums and office spaces, thermal comfort was achieved according to categories B and C, respectively, within the cold season. Additionally, for the northeast atrium orientation with 25%, 137.2 W and 189.5 W of heat loss and gain in the office zone, and 37.7 W and 204.7 W of heat loss and gain in the atrium zone were recorded. Moreover, for the northeast atrium orientation with 50%, 134.5 W and 134.2 W of heat loss and gain in the office zone, and 40 W and 192 W of heat loss and gain in the atrium zone were recorded. On the other hand, for the southeast atrium orientation with 25%, 108.7 W and 143 W of heat loss and gain in the office zone, and 68.8 W and 130 W of heat loss and gain in the atrium zone were recorded, while, with 50%, 111.7 W and 142.7 W of heat loss and gain in the office zone, and 67.5 W and 121.2 W of heat loss and gain in the atrium zone were recorded. In the warm season, the atrium and office spaces were not thermally comfortable.

“…In this view, the building has an opaque façade on the N side and double skinned facades on E, W and S sides. It also integrates a greenhouse, acting as a buffer zone, but also in the heat and mass exchanges [6]. The air purification is made by using high tech filters, but also using natural filters.…”

In this paper the authors describe a HVAC innovative system using an integrated greenhouse for heating and cooling an office building. The ventilation system allows natural (night) or mechanical ventilation and the passive cooling during the summer, including cold storage in the building structure and the PCM plywood and the refrigeration energy use during the day. Natural ventilation occurs when the wind or the Venturi effect, created by the « hat » that supports the photovoltaic panels, is strong enough; otherwise, a variable speed exhaust fan mounted on top of the building is used. The plants inside the greenhouse can produce O2 under certain conditions necessary for refreshing the ventilation air. The environment of the greenhouse allows air humidification naturally, without the use of humidifiers. If the greenhouse is sufficiently insulated in winter, it can be used in the ventilation process: the air intake from offices through the greenhouse, humidified and enriched in O2 (premixed, if necessary, with fresh air) reaches the general air treatment unit, and then sent back. The process is similar in the summer, but without recirculation, due to the humidity of the air extracted from offices. Stale air humidification enhances the thermal transfer process from the desiccant collector.
