The solar wall collects heat throughout the day and delivers it into the building as needed through the HVAC system. The graph here shows how many British Thermal Units (BTUs) the building’s HVAC system has pulled from the solar wall to introduce heat into the space over the last 24 hours.
Note: The most recent data is to the left.
Data Retrieval Time
Every hour, data is retrieved from various points across the solar wall. New hourly data may take up to 15 minutes to reflect in this report.
Solar walls are a technology used to passively heat a building. These walls combine exterior construction with interior devices to use solar energy to heat and ventilate indoor spaces.
Perforated cladding on the outside of the building is heated by the solar radiation from the sun. The solar walls are generally very dark or black in color to reduce the amount of radiation that is reflected from this wall. The system must be hooked up to the building’s HVAC system, as ventilation fans are used to create negative pressure in the air channel between the walls. This negative pressure pulls the air warmed by the sun into the building. Once this air is warmed, it begins to rise and is then fed into the HVAC system through a vent located at the top of the wall. The warm air is supplied to and distributed in the building via the HVAC system intakes.
