Light, Heat and Sound

Light (two questions)

1. Identify an interior space (or room) in a real building (could be your home or workplace), that the amount of artificial lighting isn’t enough or appropriate for a certain activity in that space. (provide one photo) Explain why do you think the artificial lighting isn’t suitable?
Provide three solutions to improve the artificial lighting quality and/or quantity. Use explanation, and your own-drawn diagram or drawing.  (8 marks, just one page)

Interior space that the amount of artificial lighting isn’t enough: Staircase which makes it difficult to walk up and down

2. Identify an interior space (or room) in a real building (could be your home or workplace), that the amount or quality of daylight isn’t enough or appropriate in a part of that space for a certain activity. (provide one photo) Explain why do you think the daylighting isn’t suitable?
Provide three solutions to improve the daylighting quality and/or quantity. Use explanation, and your own-drawn diagram or drawing. (8 marks, just one page, introduce references)

Interior space that the amount or quality of daylight isn’t enough: Garage, little to no daylight reaches the inside of the garage

Heat (two questions)

3. Identify the exterior wall of your home that the most heat transmission happens through it in summer or winter (provide a photo). Explain why did you select that wall? Draw a scaled section (1:10) from that wall and introduce materials and their thicknesses, per your knowledge and opinion. Calculate the thermal resistance of the wall. Add a layer of cavity or insulation to the wall so that its thermal resistance will be doubled. 

Exterior Wall of home that the most heat transmission happens: East Wall, as the sun rises from the east

4. Identify one place showing the use of Thermal Mass in your home (provide a photo). 
Explain how it contributes to passive cooling or heating for your home. Provide a solution to improve its thermal performance. Use explanation and your own-drawn diagram. 

One place showing the use of Thermal Mass: Brickwork around the entire house

Sound (one question)

5. Identify an interior wall or a floor in your home or workplace that unwanted sound transmission (noise) happens through it (provide a photo). Describe how the sound transmits and provide three appropriate solutions to reduce the noise. Use explanation and your own-drawn diagram. (8 marks, just one page)

Interior wall that unwanted sound transmission happens through: Thin wall between the two rooms
