This study examines technical issues of residential forced-air space conditioning systems incorporating heating, ventilation and cooling in the context of increasingly energy efficient new housing. Current technologies and practices are reviewed and analyzed with a view to improvements. Potential existing and emerging technologies and strategies are examined. A comparison of conventional and improved design strategies are presented for a house with a 5 kW heating load.
