Building Science 2

Project 1: Lighting & Acoustic Performance Evaluation and Design

Introduction

   

Lighting DESIGN is a primary element in architecture design and interior architecture. Solid volumes, enclosed spaces, colors and texture can only be appreciated fully when they are imaginatively lit. Successful buildings are those in which the lighting of the building itself and the lighting of the activities it contains together make up a unified design concept. This project is design to expose and introduce students to daylighting and lighting requirement in a suggested space.

 

In architecture and interior architecture, Acoustic DESIGN is an element which concerned with control of sound in spaces especially enclosed spaces. The requirement varies in relation to functional spaces whether it is a cinema, lecture theatre, restaurant and café or acoustical requirements for a meeting room. It is essential to preserve and enhance the desired sound and to eliminate noise and undesired sound. Prestigious buildings are those in which the acoustic of the building itself speak of the quality of the building itself. This project is design to expose and introduce students to acoustic design and acoustical requirements in a suggested space.

​

 

Objectives of Assignment

• To understand the day-lighting & lighting and acoustic characteristics & acoustic requirement in a suggested space.

• To determine the characteristics and function of day-lighting & artificial lighting and sound & acoustic within the intended space.

• To critically report and analyse the space.

 

 

Learning Outcomes   

• Able to produce a complete documentation on analysis of space in relation to lighting requirement eg. natural and artificial lighting. (Pictures, sketches and drawing) and analysis of factors which effects the lighting design of a space.

• Explore and apply understanding of building physic eg. Lighting towards building / construction technology and building materials on existing building projects.

• Able to evaluate and explore the improvisation by using current material and technology in relevance to present construction industry

• Basic understanding and analysis of lighting layout and arrangements by using certain methods or calculations eg. Lumen method and PSALI.

• Basic understanding and analysis of acoustic design layout and arrangements by using certain methods or calculations eg. Reverberation time and sound transmission coefficient.

 

Tasks - Methodology

This assignment is intended to be completed in a group of 5 students per group to evaluate their environment in terms of lighting and acoustics performances. Each group is required to choose a case study eg. gallery, visitor’s centre, showrooms, restaurants with ambiance and design and etc. Prepare a measured drawing with appropriate scale of your case study. Show all the necessary features which effect on the lighting and acoustics conditions of your case study.

They should carry out an appraisal of day-lighting artificial lighting, noise and sound condition(quality and quantity) in the selected case study. Their identification of adequacy of the quantity of light and sound/noise for the case study needed to be carried out objectively.

 

Analyse and evaluate:

            For Lighting

• The site conditions (sky condition, building orientation, etc)

• Take readings of daylight level, lighting level and photos (digital images) in the chosen case study at different times of day (morning, noon, afternoon and at night).

• Present the analysis in a lighting contour diagram.

• Quantitative analysis is required in order to present your findings in conclusions.

• Daylighting and lighting condition (identify the problems)

• Present all your findings graphically as much as possible

• Provide the calculation for the existing design.

For Acoustic

• The general site conditions (eg. Highway, main roads adjacent to your case study)

• Take readings of sound level indoor and outdoor and photos (digital images) in the chosen case study at different times of day (morning, noon, afternoon and at night).

• Present the analysis in a noise contour diagram.

• Quantitative analysis is required in order to present your findings in conclusions.

• Indoor and outdoor noise (identify the problems)

• Present all your findings graphically as much as possible

• Provide the calculation for the existing design.

                                                                                         

In order to carry out this project, each group are to collect lux-meter and sound level meter. Please be responsible in collecting, using and returning the equipments.
