Introduction:

As part of a design team, I have been entrusted to fully design the lighting scheme for the business unit. During the feasibility study it was outlined that an intelligent LED system would be utilised in the building, for the main reasons that it would be far more energy efficient than a conventional system and that over time the cost savings would eventually payback the additional cost of installing LED comfortably. Also the intelligent switching system means that the lighting should only be used when areas are occupied, and the level of light is controlled by ‘daylight-dimming’; thus equating to further savings. In order choose the correct solution for lighting a building; the following considerations should be made:

(CIBSE, 2002)

The first step to designing the lighting in the business unit is to choose a suitable lighting fitting, and use the data provided to calculate the number of fittings required in each room/area. A Thorn Quattro LED lighting fitting was chosen for the majority of this project is that in comparison to other competitors, Thorn fittings tend to have a better lumen output (luminous flux) which over the project it was hoped this would reduce the number of fittings required to adequately provide light in the building. Also, Thorn’s LED range has a good range of decorative fittings to please the aesthetical preference of the client (Thorn Lighting, 2014).

1.1 - Health & Safety Requirements:

Before calculating, all health and safety requirements should be fully considered in order to provide a safe, well-lit environment for the business unit. In order to achieve this, adequate lighting levels should be provided in each room/area in accordance with the HSE Lighting at Work (HSE, 1997), and the Society of Light and Lighting publications Office Lighting & Code for Lighting (CIBSE, 2002) (Society of Light and Lighting, 2005). It is important that all rooms/areas meet the minimum HSE requirement, but as a designer it is also important to achieve client satisfaction; so an illuminance of 500lux in all office areas has been the design parameter at the working plane (desk height of 800mm assumed). Whilst achieving these levels is important, it is of equal importance not to design a room that will be over lit; this keeps energy efficiency in check, and is less likely to impair operatives using the room/area (Sustainability Workshop, 2014).

Another important factor to consider in health and safety is the control strategy. Presence detection is to be utilised in the majority of the heavily inhabited areas in the business unit; this is ensures that the operatives don’t have to switch any lighting on themselves, and the daylight-dimming of the PIR will set the correct lux level in each room/area to allow safe occupation and safe premises for visitors (Eco-1, 2014).

1.1.2 - Installation:

When considering the installation of the proposed system, the following health and safety considerations will be made:

o All the appropriate PPE will be worn at all timeso When working at heights, a system scaffold will be usedo Safe isolation procedure will be followed at all timeso Before any contractor begins work, a site induction along with a health and safety exam

must be completedo All installation work is fully tested to ensure the system is safe to be made live

1.1.3 – Maintenance:

When considering the maintenance of the proposed building the following health and safety considerations will be made:

o All designed work has kept future risk to a minimumo The installation of all equipment is at an easily maintainable height, and spatially

appropriate to the room it is installed ino Plant room to be locked, with access only gained by signing the key and filling in an access

application at reception

4 | P a g e


o Full DB schedules will be complete for ease of future testing

1.1.3 – Operation:

When considering the operation of the proposed building, the following health and safety considerations will be made:

o All instruction will be outlined to operatives prior to occupancyo All live components are locked off, and warning signs placeo Simple control strategy to ensure all areas are well lit and fit for purpose

1.2 – Legislative Requirements:

At the request of the client, this project will be designed to the minimum standard that forms the building regulations; the subject of energy use is also covered in the Building Regulations Part L. There are two approved documents which have been in force from April 2002, they are:

o L1: Conservation of fuel power in dwellings (HM Government, 2010)

o L2a: Conservation of fuel and power in buildings other than dwellings (HM Government, 2010).

These regulations account for energy efficiency in new buildings, and also provide guidelines and values required by the engineer to design the building and its services accurately. Other legislative requirements that need to be considered whilst undertaking the entire scheme are the Health and safety at work act 1974 and CDM regulations 2007. This includes all stages of construction from design to final form. Also lighting minimum requirements must be met in accordance with the HSE Lighting at Work (HSE, 1997) and the Society of Light and Lighting publications (Society of Light and Lighting, 2005).

1.3 – Building Form and Structure:

To accurately design the lighting system within this building, it is imperative to consider the building form and structure. The client has produced detailed drawings, which include scaled layout drawings to a 3d model of the building. These detail each room within the building to scale, which furthers the efficacy of the design. Further to this, in order to calculate and design the project accurately the reflectance of the surfaces has been assumed (detailed in section 2.1) and for ease of installation of the lighting a ceiling grid is to be installed (Thorn Lighting, 2014).

1.4 – Spatial Arrangement:

Using a 600x600mm ceiling means that all other services can be above the ceiling, with the majority of the lighting fittings slotting directly into the grid evenly spaced. This differs in the reception, and landing areas as radiant panels have been used to heat the areas. Considering this, a Thorn Equaline lighting fitting has been used, which is a wall fitting that outputs light downwards and upwards. This will be installed using the wall cavities, and the calculation has been amended accordingly. Another spatial consideration is that the store room will be used a riser for the services, this due to the fact is

5 | P a g e


safe to use this room and it is immediately above the plant room, a separate lighting and power distribution board will be installed the ground floor plant room. The distribution boards will be located in the ground floor plant room. All containment for electrical services will be above ceiling in perforated basket. Care will be taken with the routing of the containment as to avoid clashing with other trades/services.

Also, a spacing formula has been applied in section 2.2 to all fittings to give the maximum distance apart they can be in an attempt to achieve uniformity. Complete uniformity is impossible in practice, but an acceptable standard is for the minimum to be designed at 0.8 (or 80%) of the maximum illumination level. This expressed with the following formula:

Maximum Illuminance=5000.8

=625 lux

This means, for the majority of office rooms with an illumination level of 500 lux, if this is taken as the minimum level, then the maximum level in another part of the room should be no higher than 625 lux.

1.5 – Aesthetics:

The client has prioritised the business unit, aesthetically speaking, is up to modern standards and appealing to any company wishing renting the premises. Thorn’s LED range has a good range of decorative fittings to please the aesthetical preference of the client (Thorn Lighting, 2014), and the Quattro fitting was chosen particularly to suit this. They can also be chosen to effectively match the colour schemes or design of the rooms. In additional, the lighting in the reception area and landing uses bi-directional wall lighting fittings which will look quite striking on entering the building without compromising heavily on energy efficiency. All services for the lighting will be above ceiling, and even the switching arrangement means there will be minimal controls on walls etc.

1.6 – Energy Efficiency:

The client has detailed energy efficiency as a main priority. Considering this at an early design stage is important to achieve a final product that is energy efficient. This can be achieved through many different guises such as, zoning, controls and accurate design and can furthered by the use of renewable energy forms (HM Government, 2010). Lighting must provide a suitable visual environment within the room/area, sufficient for the performance of a range of tasks, provision of a desired appearance etc. This should be achieved without waste of energy (CIBSE, 2002). On this project, this has been mainly achieved through LED lighting and the intelligent controls controlling it. Section 2.4has a detailed saving calculation of using LED fittings as opposed to using fluorescent fittings, but in brief LED’s require greatly lower wattage to output the same amount of light as a conventional lamp, so this obviously vastly improves efficiency (Ice Energy, 2014). Secondly, with the installation of an intelligent switching system with an

6 | P a g e


in built photocell in rooms/areas receiving natural daylight, this allows for the usage of the lights combined with the natural daylight to meet the HSE set parameters (JCC Lighting, 2015). Absence detection has been selected for the majority of the isolated office areas, as this will reduce the usage by up to 60% compared to a conventional switching arrangement (Sustainability Workshop, 2014). The switching of circuits is almost entirely confined to the beginning and end of a period of occupation; people may switch lighting on when entering a room but seldom turn it off until they all leave (CIBSE, 2002). Using this system means the lights will not be switched on or left on in rooms or areas when they are not required, thus further saving on energy consumption. This is important both in terms of reducing the cost of energy bills, and also in reducing the environmental impact of the building

Task 2 – Technical Design:

2.1 – Lighting Calculations:

(Please find attached all lighting spread sheet calculations in Appendix ‘A’)

In order to produce an accurate design for each room/area, a spread sheet was created based on the following Lumen Method calculation:

N= E× AF×UF× LLF

Where:N = Number of Fittings/LampsE = Required Illuminance (HSE, 1997)A = Area of Room (m2¿F = Available Flux (lm) (Thorn Lighting, 2014)UF = Utilisation Factor (see below) (Thorn Lighting, 2014)LLF = Light Loss Factor (Typical Values) (HNC Course Notes, 2014) (JCC Lighting, 2015)

In order to calculate the utilisation factor the Room Index must be obtained using the following formula:

RI= L×WH ×(L+W )

Where:L = Length of Room/Area (m2¿W = Width of Room/Area (m2¿Hm= Height of Luminaire above Working Plane (m)


In the data supplied for the lighting fitting, a utilisation factor table can also be used (appendix ‘B’). The following reflectance has been assumed:

Fabric ReflectanceCeiling 50

7 | P a g e


Walls 50Floor 20

This equates to a Room index of 0.71. This is then calculated using the following:

0.71×Calculated Room Index=UF

LLF:

(JCC Lighting, 2015)

2.1.1 – Example Calculation:

Admin Office:

E = 500 (HSE, 1997)A = 7.735 X 2.663 = 20.6F = 3200 (Thorn Lighting, 2014)UF = 0.67 (see below)LLF = 0.98 (HNC Course Notes, 2014)

Room Index = 7.735×2.663

2.1×(7.735+2.663)=0.94

∴UF=0.94×0.71=0.67

N= 500×20.63200×0.67×0.98

=4.9

Total Number of Fittings = 5

To provide Luminance Uniformity and due to the shape of the admin office, I think it would be pragmatic to install 6 no. lighting fittings. Luminance uniformity is the ratio of minimum luminance to average luminance (CIBSE, 2002), calculated using the following:

ΔL=[L(MAX )/L(MIN ) –1]X 100

This figure should be outlined in the specification and can only be measured using a light meter once installed. Using the lumen method and applying practical design thinking can eradicate non-uniform lighting at the design stage.

8 | P a g e


2.2 - Spacing Formula:

Once the number of fittings has been derived, the space between them can then be considered to ensure the correct spread of light. This calculation ensures the maximum distance permitted between lighting fittings is not exceeded; this is achieved using the following formula:

Smax=1.34×H m

Where:Smax = Maximum distance between fittings (m)1.34 = Obtained from Thorn data sheet (Thorn Lighting, 2014)Hm = Height above working plane (m)


2.2.1 - Example Calculation:

Admin Office:

Smax=1.34×2.1=2.814m

So a maximum distance of 2.81m is permitted between each fitting in the Admin Office

2.3 – Running Cost Comparison:

Although previously discussed in the feasibility study, now the total number of 600x600 modular fittings is available (82), an accurate running cost comparison can be made based on 100,000 hours use and a kWh price of 15.25p (British Gas, 2014). Please refer to the following table:

LED FluorescentTotal Luminous Flux 3200 4800Number of Fittings 89 89Installation Cost (Parts Only) £287.88 x 89 = £25,621.32 £93.22 x 89 = £8,296.58Replacement Frequency (100,000 hours use)

2 13

Replacement Cost (2 x £119.29) x 89 = £21,233.62

(13 x £34.29) x 89 = £39,673.53

Energy Use (100,000 x 0.042) x 89 = 373,800 kWh

(100,000 x 0.063) x 89 = 560,700 kWh

Running Costs 373,800 x 0.1525 = £57,004.50 560,700 x 0.1525 = £85,506.75Total Cost Comparison £103,859.44 £133,476.86

As is plain to see, to just simply consider the installation cost when choosing the lighting method would be very short sighted in terms of cost and efficiency. To see this as a percentage saving for the use of LED’s, please refer to the following:

9 | P a g e


Precentage Saving=133,476.86−103,859.44133,476.86

×100=22.19%

2.4 - Control Strategy:

(Please see attached Schematic drawing in appendix ‘C’)

“The aim of a control system is always to ensure that the lighting is only operating when it is required, and that when it is, it is operating in the required state” - (CIBSE, 2002)

2.4.1 -Presence Detection:

Presence detectors sense moving infra-red heat and switch on their loads and start a timer. When the time elapses the unit switches off. The timer runs down from the last movements detected and will stay on as long as there is movement across the zones of detection (Danlers, 2014) (JCC Lighting, 2015). Presence detections preferred use is in areas regularly populated by several people.


2.4.2 – Absence Detection:

Absence detectors are operated by a switch as normal but when the person leaves the room they turn off the load after a pre-determined timed period (Danlers, 2014) (JCC Lighting, 2015). Absence detection is usually used in isolated offices or less populated rooms. The same unit is used for both, an Ex-Or LightSpot HD (Ex-Or, 2014) (data sheet attached); this is because presence detectors can be linked out to turn it into an absence detector, the only wiring difference is absence detection requires switching on entering the room.

10 | P a g e



2.4.3 – Daylight-Dimming:

The use of these in all rooms/areas is designed to utilise any natural daylight to meet the required illuminance, thus reducing the output of the fittings it switches. The switching of fittings in each room has been carefully deliberated to consider this, as lighting fittings near windows will use more natural daylight than the fittings in closer proximity to walls. This is important to achieve uniformity, and to reduce the output of the necessary fittings (JCC Lighting, 2015).

2.4.4 – Mains Controls:

To reduce the total usage of the building as a whole, a lighting contactor panel will be used that utilises a time clock. This will ensure that after the set parameters have been met (prior to occupancy), the timer will disconnect the contactor and the lighting system can no longer be switched. For fire safety and other health and safety considerations a manual override of this can be achieved in the reception through a break glass.

2.4.5 – LiGO Control System:

(Please find attached LiGO brochure in appendix ‘B’)

“LiGO allows you to set up the system, create reports and adjust settings. It gives you access to a range of features including: time zone control, emergency override, alarm reporting, energy graphs,

and emergency reporting.” - (Open Technology, 2014)

These simple stand-alone controls would work fine, but in order to sufficiently monitor and react to breakdowns, the lighting controls will incorporate a ‘LiGO’ system (Open Technology, 2014). This intelligent system will be

11 | P a g e


integrated with the BMS system that is to be installed as part of the control system for the heating and ventilation systems. The main advantage of utilising this system is that the lighting can be controlled and monitored remotely by trained engineers; and each light fitting is fully addressable and can be remotely controlled. This includes, switching, testing, dimming etc. The only requirement from the fitting is that it is fitted with “DALI” compatible controls, which was considered when originally selecting the fittings used for this project (DALI, 2014). All settings, with regards daylight dimming and detection can be retrospectively adjusted remotely by an engineer with any device with an internet connection. This software and operational information can also be passed on to the occupier’s maintenance department for their own use.

2.5 – Containment:

(Please find attached layout drawing in appendix ‘C’ that details containment route)

This project will be wired using twin and earth. This wiring will be contained in 150mm x 150mm Pemsa basket to each location, then from each main run all-round-band will be used to wire to local ceiling mounted Kliks multi-way ceiling rose boxes. A logical approach to routing containment has been used to reduce the amount used, which further reduces cost of materials and labour of the project. Also, with using basket and twin and earth, there are no grouping factors to consider when sizing cables and loads as there is air circulation available to the cables; the only consideration is to ensure the cable basket has ample room for all electrical services (IET, 2011).

2.6 – Cable Sizing:

Each circuit will fed using a BSEN60898 6A MCB. Now the total number of fittings and layout drawings have been produced, all the relevant information is available to size the cable for the project. Using my own knowledge, the cable size that should be used is 1.5mm2 conductor with a 1mm2 CPC. The use of BS7671 17th Edition Wiring Regulations (Table 4D5) and the following example of circuit 1L2 is to demonstrate this:

TotalCurrent ( A )=W ×N ×CFV

Where:A = AmpsW = Wattage of FittingN = No. of Fittings on CircuitCF = Correction Factor (50%) (IET, 2011)V = Voltage

A=42×17×1.5230

=4.65 A

Now to check the Volt Drop (mV/A/m is obtained from table 4D5 (IET, 2011)) of the run using the following formula:

12 | P a g e


Volt Drop(V )=(mV / A /m)×Ib×L

1000

Where:mV = MillivoltsA = AmpsM = MetreIb = Design CurrentL = Length

Volt Drop (V )=29×4.65×501000

=6.7V

As BS7671 states, a maximum permitted volt drop of 3% (6.9V) is allowed (IET, 2011), so this falls within this parameterFinally:

¿≥ ¿Ca×Cg×Cr×Ci

Where:It = Current carrying capacity of cable (Tabulated in 4D5) (IET, 2011)In = Rated current of protective deviceCa = Ambient temperature correction factor (Tabulated in 4C2 - 30℃ selected) (IET, 2011)Cg = Grouping correction factor (From Table 4B1) (IET, 2011)Cr = Protective device correction factor (Cr = 1 – stated in On-Site Guide (IET, 2011))Ci = Thermal insulation correction factor (Tabulated in 6C, On-Site Guide – 0.71 selected) (IET, 2011)

¿≥ 6 ( ¿ )

1×1×1×0.71=8.4 A

Now simply select cable size from table 4D5 (IET, 2011):

o 1.0mm2 Twin and Earth cable could be used with a current rating of 16A with the method of installation used.

o Considering potential future expansion, and considering the future volt drop 1.5mm2 is selected with a 20A current carrying capacity

2.6.1 – Amtech:

(Please find attached a report from Amtech single cable design in appendix ‘C’, that furthers these findings (Amtech, 2014).)

Amtech is a system that uses all the relevant information, such as load and total length, to provide the correct cable size for any given project. This was used to ensure the physical methodology used to calculate the cable size was correct. It also has a large database with all correction factors for specific branded protection devices.

13 | P a g e


2.7 – Loading and Balancing:

(Please find attached Schematic and DB schedule in appendix ‘C’)

The load of each lighting circuit has been carefully considered as not to overload any circuits. Also all circuits are balanced equally across the 3 phases of the supply.

2.8 – Final Costing:

(Please find attached final cost estimation for the account in appendix ‘D’)

A final account of £47,987.93 excluding variations is due for this project on completion. This has been estimated using accurate equipment costs from wholesalers, and a calculated labour rate (please see attached spread sheet). The labour costing takes into account all variables such as overtime, and the inclusion of transport etc. Also, the labour and materials include a 15% mark-up to achieve parity and profit on completion.

Conclusion:

(Full evaluation collaborated as a group, available in group evaluation section)

To evaluate, I feel this design meets all the client’s needs and also excels in energy efficiency and cost reduction. Also, if this project came into fruition, it would only need a few minor changes to detail and it would be a fully plausible system. Personally, I found this project more suited to my skill set, and have also gained valuable experienced whilst carrying out this design.
