Editing Trombe wall (section)

=== Disadvantages ===
* Since the Trombe wall is consolidated in one building element - only the equator-facing facade - its impact on the overall building design is limited when compared to roof ponds or direct-gain systems.<ref name="Myers1984" />
* Natural daylight is lost in the full-height Trombe walls unless the system is combined with a direct-gain system or windows are introduced.
* Wall hangings or other type of coverings are not allowed on Trombe walls as they block the radiation emitted from the interior surface of the wall at night.<ref name="Lechner" />
* The living spaces behind the Trombe walls need alternative access to natural daylight to prevent these spaces from being claustrophobic.
* If a Trombe wall is constructed with upper and lower vents, the upper vent on the thermal mass can suck the heated air from the warmer indoor spaces to the cooler air space between the mass and the glazing (reverse-siphon) at night. To avoid this, it is necessary to use back-draft dampers.<ref name="Myers1984" />
* In regions closer to the equator, although summer ventilation can help to ameliorate overheating, insulating and shading the Trombe wall can minimize this overheating during the hot season.<ref name="Michels1979"/>
* It is a very climate-dependent system and external temperature and incident solar radiation levels have a significant role in the energy savings and {{CO2}} emission reductions of Trombe walls.<ref>{{cite journal |last1=Zhang |first1=Hongliang |last2=Shu |first2=Haiwen |title=A Comprehensive Evaluation on Energy, Economic and Environmental Performance of the Trombe Wall during the Heating Season |journal=Journal of Thermal Science |date=November 2019 |volume=28 |issue=6 |pages=1141–1149 |doi=10.1007/s11630-019-1176-7 |bibcode=2019JThSc..28.1141Z |s2cid=210004208 }}</ref> Even though Trombe walls built in hot-summer and warm-winter zones provide more energy savings per unit wall area compared to a conventional wall, they display a poorer economic performance if solar radiation is low during the heating season.
* The system requires user action to operate movable insulation or shutters, often on a daily basis.
* In regions where the local users are not familiar with the system, to get the maximum performance from the Trombe wall system, users can be given guidance either by modeling a prototype or providing a user-friendly operation manual for the wall during different seasons or days.<ref>{{cite journal |last1=Dabaieh |first1=Marwa |last2=Maguid |first2=Dalya |last3=El-Mahdy |first3=Deena |last4=Wanas |first4=Omar |title=An urban living lab monitoring and post occupancy evaluation for a Trombe wall proof of concept |journal=Solar Energy |date=November 2019 |volume=193 |issue=15 |pages=556–567 |doi=10.1016/j.solener.2019.09.088|bibcode=2019SoEn..193..556D |s2cid=209989406 }}</ref> This participation can lead to post-project acceptance of the Trombe wall idea and make it easier for locals to reproduce it locally.
