INSTRUCTIONAL OBJECTIVES In order to equip the students with the scientific background required to design climate responsive buildings, a clear understanding of the various climate elements. - radiation, air temperature, humidity and wind speed as tools of design is intended. It also includes the articulation of the building into its various components in response to the above mentioned climatic elements. UNIT I CLIMATE &THERMAL COMFORT 7 Global climatic factors, elements of climate, classification & characteristics of tropical climates, site climate. Thermal balance of the human body, Thermal comfort indices Effective temperature, CET, comfort zone & calculation of overheated &under heated periods. UNIT II PRINCIPLES OF THERMAL DESIGN IN BUILDINGS 6 Thermal quantities heat flow rate, conductivity (k value ) & resistivity, conductance through a multi-layered body, surface conductance, transmittance calculation of U- value convection, radiation, concept of sol-air temperature & solar gain factor exercises in heat loss & heat gain in building assuming steady state assumption (thermal balance equation ).Periodic heat flow in building time lag & decrement factor & its application in selection of appropriate

4 materials for walls & roof. Effect of Insulation & cavity on time lag & its practical use.exercises on achieving the required indoor temperature by varying the components of composite materials according to the U values. UNIT - III VENTILATION & DAY LIGHTING 5 Functions of ventilation stack effect due to the thermal forces, wind velocity wind rose diagram, wind pressure. Air movement through building &around buildings factors affecting indoor air flow, wind shadow etc. The nature of light, its transmission, reflection colored light, the munsell system photometric quantities illumination, day lighting prediction the daylight design graph. UNIT IV SOLAR GEOMETRY &DESIGN OF SUNSHADING DEVICES 6 Apparent movement of the sun, sun path diagrams (solar chart) solar angles, Shadow angles, solar shading masks. Etc Exercises on plotting isopleths, transfer of isopleths to solar chart, fitting a shading mask over the overheated period & design of sun shading devices for different orientations. UNIT - V DESIGN FOR CLIMATIC TYPES 6 Building design & lay out planning consideration for warm humid, hot dry, composite & tropical upland climates, climatic data sets analysis climate graph the Mahoney tables & its recommended specification. Exercises on design of small buildings for various climates. Detailed Session plan: TOTAL 30 Lecture No Topic UNIT I: CLIMATE &THERMAL COMFORT 7 Lecture Hours
