• attaching each of a plurality of Peltier based thermoelectric units to a divider such that a first ceramic plate contacts the divider and faces a first half of the wall air duct which is attached to the second wall and a second ceramic plate extends into a second half of the wall air duct;
• joining the second half of the wall air duct to the roof air duct;
• attaching a first vent to a junction between the air gap and the roof air duct;
• installing a first fan in the first vent;
• attaching a second vent to a junction between the first half of the wall air duct and a building interior;
• installing a second fan in the second vent;
• installing a first grate in the first wall near the floor, wherein the first grate is configured to provide a first air flow passage between a building interior and the air gap;
• installing a second grate in the wall air duct near the floor, wherein the second grate is configured to provide a second air flow passage between an exterior environment and the wall air duct;
• providing, by a controller connected to the rechargeable battery, power to each of the plurality of Peltier effect based thermoelectric units;
• generating, by each of the plurality of Peltier effect based thermoelectric units, a temperature differential between the first ceramic plate and the second ceramic plate;
• actuating, by the controller, the first fan to suction air through the first grate, through the air gap, and through the roof air duct, and to expel the air through the first vent to the exterior environment;
• and
• actuating, by the controller, the second fan to draw air through the second grate into the wall air duct, through the first half of the wall air duct, and through the second vent, and expel the air into the building interior.
