PH8201 – SYLLABUS
UNIT I THERMAL PERFORMANCE OF BUILDINGS
Heat transfer through fenestrations, thermal insulation and its benefits. Heat gain and heat loss estimation — factors affecting the thermal performance of buildings.
Thermal measurements, thermal comfort, indices of thermal comfort, climate and design of solar radiation, shading devices Central heating. Principles of natural ventilation — ventilation measurements, design for natural
ventilation. Window types and packaged air conditioners — chilled water plant — fan coil systems — water piping — cooling load. Air conditioning systems for different types of buildings — Protection
against fire to be caused by A.C.Systems.
UNIT II ACOUSTICS
Classification of sound- decibel- Weber–Fechner law — Sabine?s formula- derivation using growth and decay method. Absorption Coefficient and its determination –factors affecting acoustics of buildings and their remedies. Methods of sound absorptions — absorbing materials — noise and its measurements, sound insulation and its measurements, impact of noise in multi-storeyed buildings.
UNIT III LIGHTING DESIGNS
Radiation quantitites — spectral quantities — relationship between luminescence and radiant quantities — hemispherical reflectance and transmittance — photometry: cosines law, inverse square law. Vision — photobic, mesophic, scotopic visions. Colour — luminous efficiency function — Visual field glare, colour — day light calculations — day light design of windows, measurement of day-light and use of models and artificial skies, principles of artificial lighting, supplementary artificial lighting.
