Makes general suggestions for future buildings and their ventilation methods with the aim of creating improvements to avoid the faulty design of the 1960's with their high energy consumption. Considers the characteristics of natural ventilation and mechanical ventilation with respect to ventilation heat loss. Recommends the use of `ventilation on demand' for bathrooms, w.c.'s and kitchens using individual extract ventilation units for each room. Considers the growing importance of heat recovery from exhaust ventilation air, with heat pumps as the most likely units used in this application.
