The objective of this coursework is for you to develop daylight and electric lighting assessment and basic design skills. You are asked to prepare a report covering the lighting in a two-person office.

Throughout this coursework, please state all the assumptions that you make.

The Room

This study relates to the lighting in a cellular office room in London (Lat: 51.5267, Lon: -0.1298). The room is used as a two-person office and is occupied most weekdays from 08:00 in the morning to 18:00 in the evening. Details of the room are given on the room details sheet.

Daylight in the Room

To assess the daylight availability in the room, build a grid of points following EN 17037 recommendations and manually calculate the percentage of the working plane with an illuminance from daylight of at least:

a)   100 lux

b)   300 lux

c)   500 lux

over at least half of daylight hours in a year. In the manual calculations, you may use relevant methods described in BRE Digests 309 and 310.

Interpret the results to assess the daylight availability in the room.

Sunlight in the Room

Check to see how many hours of sunlight the room can receive on 21st March. Interpret the results to assess the sunlight availability in the room.

Electric Lighting Design

Use utilisation factors to calculate the number of each type of luminaire necessary to meet the requirements of the SLL Code for Lighting. Select the luminaire type that is best for the room and check your design for the chosen luminaire type using DIALux. Details of the luminaires are given in the datasheets included at the end of this document.

Lighting Controls

Develop a lighting control strategy for the room and explain the advantages ofthe controls used in terms of user comfort and energy saving.

Also estimate the energy saving for electric lighting that could be achieved through the use of the proposed lighting controls.

Method Review

Consider the methods that you have used in the sections above and comment on their accuracy and any assumptions that they depend on. Expand on limitations of the methods and assumptions used and discuss what you would recommend for further improvements to the lighting of the space.

Additionally, reflect on what you might have done differently or included in the assessment, and explain how you would have implemented those changes.

Submission

Submit your report as a PDF document to the BENV0058 Lighting Fundamentals Moodle webpage by 11:00 (GMT) on 09/12/2025. The document should be clearly set out and have no more than 3,000 words (excluding annexes). Working should be shown either in the main text or an annex.

Standard penalties may be applied to overlength or late submissions.
