OBJECTIVES

 The main objective of this course is to provide an indoor setting that is healthy for the occupants, and enhances well-being, performance and productivity.

UNIT I INTRODUCTION

Introduction-sources and type of indoor pollutants-types-effects-Building related illness-Sick building syndrome— fundamental calculations -contaminant exposure level-Indoor air quality standards.

UNIT II TYPE OF INDOOR ENVIRONMENT

Components and classification – industrial ventilation system -Special indoor environmentHospitals –-transportation-recreation building-commercial buildings-pollutants-human responses to indoor environment-lighting-acoustic environment-odour-thermal comfort.

UNIT III MONITORING AND MEASUREMENT TECHNIQUES

Instrument and methods-Instrument selection process- Sampling and analysis -sensorsEstimation of pollution emission rate- emission factors-puss diffusion-evaporation and diffusion-drop evaporation-leaks-problems.

UNIT IV PREVENTION AND CONTROL OF INDOOR POLLUTION
