With over 100 references, the document is divided into sections on: previous international energy studies, ventilation rate standards and requirements, mechanical ventilation, "mixed mode" or "hybrid" systems, natural ventilation, infiltration in schools, and indoor air quality.

Increased concern over the adverse environmental impact of energy use has encouraged the design and construction of energy efficient buildings, and many are suited to natural ventilation. In the temperate UK climate, naturally ventilated buildings can provide year round comfort, with good user control, at minimum capital cost and with negligible maintenance. The principle of good ventilation design is to 'build tight - ventilate right'.
