1. A system for using outside ventilation air to maintain indoor comfort and air quality, comprising:
- a sensor system for detecting outdoor and indoor air temperatures;
an air delivery system for delivering the outside ventilation air to an interior space; and
a programmable controller, operably connected to the sensor system and the air delivery system, that includes;
a recovery element that receives an outdoor air temperature and an indoor air temperature detected by the sensor system;
a storage element that stores the detected outdoor air temperature and the detected indoor air temperature detected by the sensor system;
a calculating element that automatically calculates a predicted indoor temperature range and a predicted outdoor temperature range based on the stored outdoor air temperature and the stored indoor air temperature; and
a regulating element that automatically regulates operation of the air delivery system as a function of predicted indoor and outdoor air temperature ranges and a predetermined indoor air temperature range.

Abstract
A system and method for cooling and heating of buildings comprising an integrated assembly of devices, including a variable speed air handler, hot water heating coil, outside air damper, controller, and optional compressor-based air conditioner. During the summer the system utilizes nighttime outside air for cooling and uses air temperature predictions to provide information about optimal control settings and to maintain comfort. During the winter the system varies airflow with heating demand and ventilates with outside air to maintain indoor air quality.
