AR3503 Electricity, Lighting and Acoustics in Buildings Syllabus – Anna University Regulation 2021

OBJECTIVES

 To give familiarity about the different requirements of electrical services in a building.
 To give knowledge about sources, principles, products and design of lighting from artificial sources.
 To give knowledge about basics of acoustics and acoustical design of buildings.

UNIT I GENERATION OF ELECTRICITY AND DISTRIBUTION IN BUILDINGS

Generation of electricity. Ohms and Kirchoffs laws. Units: watt, volt, amps. Distribution from grid to facilities. Two phase and three phase systems. Substation, transformers, wires and conduits, distribution boards, meters, switch boards, earthing, lightning conductors. Generators, inverters. Electrical load estimation and electrical wiring design for a small building/ campus.
Site visits with documentation in the form of sketches/ drawings/ photos. Understanding of products, product catalogues for a small building.

UNIT II ELECTRIC LIGHTING

Laws and terminologies of light and lighting. Light from artificial sources, quantity and quality. Types of lamps and luminaires. Applications and choice of luminaires. Lighting level for different uses in outdoor and indoor environment. Supplementary electrical lighting.
Site visits with documentation in the form of sketches/ photos. Understanding of products, product
catalogues.

UNIT III LIGHTING DESIGN FOR BUILDINGS

Lighting calculations. Brief overview of lighting simulation and performance analysis using software. Design exercise involving lighting design for appropriate projects of simple scale through choice, calculations, layout, drawings, physical models.

UNIT IV FUNDAMENTALS OF ACOUSTICS

Fundamentals – sound waves, frequency, intensity, wave length, measure of sound, decibel scale, speech and music frequencies. NC curves. Permissible noise limits. Material property – absorption, reflection, scattering, diffusion, transmission. Absorption co-efficient, NRC, Sound Transmission Class (STC), Impact Insulation Class (IIC).Understanding acoustic properties of materials/ products through study of product literature/ site visits. Environmental noise and its control. Structure borne and air borne noise control. Site selection. Sound in enclosed space: Reverberation time, optimum reverberation time, echo, early decay time. Architectural acoustics. Importance of shape volume, treatment for interior surfaces, etc.

UNIT V DESIGN FOR ACOUSTICS

Basic principles in acoustic designing of classroom, lecture and conference hall, offices, open air theatre, auditorium, concert hall, theatre, cinema, recording studio. Understanding of drawings/ details related to real acoustic design projects. Site visits with documentation in the form of sketches/ drawings/ photos Simple problems based on reverberation time and absorption coefficients.

OUTCOME

 Ability to understand electrical services in a building.
 Ability to design artificial lighting in a building.
 Knowledge of principles of acoustic design in different building typologies.
