“…The air temperature sensors were shielded with a metal cylinder from radiation. The operative (globe) temperature sensors were covered with 40 mm diameter grey globe spheres, ensuring the same relative influence of air and mean radiant temperature on the sensor as on a clothed person [32] [33] [34].…”

“…Here it was shown that the orientation has an impact on the overheating magnitude in the studied object. Even though not investigated, this statement was also made by other Danish researchers [4,32]. Among the built projects, several buildings were oriented towards a specific orientation-mostly south with the primary purpose being to enhance thermal comfort and the reduce energy need [33][34][35][36][37][38].…”

Due to climate change, the rise in global temperature causes an increased need for cooling to satisfy occupants’ thermal comfort. Application of architecture passive design strategies, so-called bioclimatic architecture strategies, based on the local climate to forego active cooling measures to decrease the conventional heating need and ensure thermal comfort are, thus, becoming highly relevant and vitally important. In an effort to adapt and promote passive architecture design strategies in the new design or renovation of building projects, this literature review fills the gap by identifying suitable bioclimatic architecture strategies in the Danish setting. The literature review adopts the PRISMA flowchart (Preferred Reporting Items for Systematic Reviews and Meta-Analyses), and the outcome is supplemented by screening 25 actual bioclimatic architecture-based building design projects in Denmark. The study shows that a wide range of passive strategies are being researched and practiced in Denmark, whereby the focus for passive heating strategies lies on solar gains, thermal insulation and thermal mass. Among passive cooling strategies, natural ventilation and solar shading are the main strategies investigated. Based on the analysis, it is expected that the use and research of those measures will continue, whereby the passive cooling measures will be of particular future interest in light of increasing outdoor temperatures.

“…With regard to the first aspect, some numerical analyses indicated that energy use could be reduced by choosing appropriate setpoints [5,6]; conversely, the adoption of only one thermostat may be deficient in certain occupancy cases [7,8]. Controller tuning by setpoint regulation often provides relatively low-or no-extra-cost solutions for existing buildings [9].…”

Effect of HVAC’s Management on Indoor Thermo-Hygrometric Comfort and Energy Balance: In Situ Assessments on a Real nZEB

This paper proposes the analysis of real monitored data for evaluating the relationship between occupants’ comfort conditions and the energy balance inside an existing, nearly zero-energy building under different operational strategies for the heating, ventilation, and air-conditioning system. During the wintertime, the adaptive comfort approach is applied for choosing the temperature setpoint when an air-to-air heat pump provides both heating and ventilation. The results indicate that in very insulated buildings with high solar gains, the setpoint should be decided taking into consideration both the solar radiation and the outdoor temperature. Indeed, when the room has large glazed surfaces, the solar radiation can also guarantee acceptable indoor conditions when a low setpoint (e.g., 18.7 °C) is considered. The electricity consumption can be reduced from 17% to 43% compared to a conventional setpoint (e.g., 20 °C). For the summertime, the analysis suggests the adoption of a dynamic approach that should be based on the outdoor conditions and differentiated according to room characteristics. Considering the indoor comfort and the maximization of renewable integration, the direct expansion system has better performance than the heat pump; this last system should be integrated with a pre-handling unit to be energy convenient.
