(b) Ballast shall not exceed 6W

6.3 Lighting Intensities

(a) Table 14 sets performance criteria for lighting intensities W/m².

6.4 Exterior Building lighting

(a) Net area intensities shall not exceed 5 W/m²

6.5 Lighting Controls

(a) All lighting systems (except emergency) to be provided with controls.

Lighting loads exceeding 100W should have automatic control.

(b) Lighting zones for daylighting control, switching zones < 30m².

4 Review of MS1525 Ed 2007; Section 6 Lighting

Section 6 – Table 13 (illuminance level) & Table 14 (energy Intensities)

Working Area E Level (Lux)Power Rate

(W/m²)

Restaurants 200 lux 15 W/m²

Offices 300 – 400 lux 15 W/m²

Classrooms/lecture theatres 300 – 500 lux 15 W/m²

Auditoriums/Concert HallsRefer MS8993

(200lux) 15 W/m²

Hotel/Motel/Guest Rooms Refer MS 8993 15 W/m²

Lobbies/Atrium/Concourse 100 lux 20 W/m²

Supermarkets/Dept Store/Shops 200 – 750 lux 25 W/m²

Store/Warehouse/Corridors/Toilets 100 lux 10 W/m²

Car Parks 100 lux 6 W/m²

This table summarises the prescriptions contain in Tables 13 and 14 of MS1525-2007. We note that

prescription is simple and the type of space listed small. Some criticism of MS1515-2007 is the lack

of prescription which may conflict with local laws and regulations e.g. min. Lighting level for car park

for reasons of security. Another criticism is the Power Intensity (W/m²) are too relaxed.

17 June 2013

Revision to Section 6 of MS1525-2007 are summarised in this slides.



7 Draft MS1525 Ed 2013; Min. Safety Standard

New Sub Section inserted at Preamble.

Requirement that safety standard must be complied before

considering E.E.

In 2007 Edition, this is not explicitly stated BUT is implied.

Min. Safety Standards:

MS-ISO 8995 – Lighting for Indoor Work Places

MS-ISO 825 Part 1 & 2 – Code of Practice for the design of

road lighting

Min safety standards requires that lighting comfort such as

glare, uniformity, colour have to be taken into consideration.

17 June 2013

The insertion of this sub section is to explicitly assert the primacy of safety standards over E.E. Frequently (from feedback) many green-practitioners and lighting vendors only focused on energy savings whilst other issues such as glare control, uniformity of illuminance (or luminance), colour (or CRI) are not given sufficient attention. The light distribution characteristics of a lamp (polar diagram) in many cases affect minimum safety standards, which is addressed in design, and have a direct effect on energy efficiency.



8 Draft MS1525 Ed 2013; Min. Safety Standard

1st Week August

TC Lighting is embarking on a series

of Work Shop on MS-ISO 8995 & 825.

Copies of MS-ISO at deep discount.

17 June 2013

TC Lighting (main committee under ISC-E), is embarking on a nation-wide workshop on proper design of lighting based on the MS-ISO 8995 and 825. Members who are keen to obtain copies of the standards at steeply discounted price should attend these workshops.



9 Draft MS1525 Ed 2013; Table 13 Il luminance

Add CRI Column

Table 13 of MS1525-2007 contains prescription on lighting level (illuminance or Lux). The MS1525-2013 adds a column on CRI (Colour Rendering Index). The following slide explains why CRI is added.



10 Draft MS1525 Ed 2013; Table 13 Il luminance

Add CRI Column

Why ADD CRI ?

1. Colour Rendering Index

(CRI)

2. CRI in sustain reading

application is a health

issue.

3. Min. Safety standard

require CRI > 80 for

sustain reading activities.

4. CRI has a STRONG

correlation to lamp

efficiency for Solid State

Lamps (SSL).

17 June 2013

The reason for adding CRI is an issue of health. In detail reading activity, office, classroom etc, CRI >80 is mandatory under MS-ISO8995. Correlation between CRI and lamp efficiency is principally an issue related to SSL (Solid State Lamps). It many cases of application, practitioners are only focusing on efficiency of lamps neglecting health issues related to CRI.

Lumens output from a standard 7W LED ‘light bulb’.

Edison (Taiwan) Luxeon (USA) Cree (USA)

Cool White (CRI < 80) 385 lumens

(55 lumens/W) 315 lumens


(80 lumens/W)

Warm White CRI > 80) 315 lumens



(62 lumens/W)

The table (of typical LED) shows lamp efficiency impacted by CRI.



11 Draft MS1525 Ed 2013; Ballast Losses

17 June 2013

2007 Ed –

6W

Losses for hi-

pressure

discharge

lamps added.

Revision to ballast loss is expected to change market demand for higher quality ballast. The current (and previous MS1525-2007) mandated ballast loss is at 6W. The new standard sets 4W as the baseline. Ballast losses for high pressure discharge lamps are also introduced in the 2013 edition.



12 Draft MS1525 Ed 2013; Power Intensities Improved

17 June 2013

2007 Ed values of

power intensities

too high /easy

2013 Ed Lux level

correlated with power

intensities

2013 Ed power intensities

at lower values

Table 15 in MS1525-2007 prescribes Power Intensities. The 2013 edition revises Table 15 by:

(a) Increasing the types of space-usage prescribed by correlating with the type of space-usage listed in Table 14;

(b) Add a column on prescribed lux level (as a guide) (this will, in the next slide shows correlation between Power Intensities and Lux level); and

(c) Improved Power Intensity. Common criticism against the 2007 edition is the simple and relatively low level of compliance for Power Intensity.

Note: “Low” in this context does not refer to the value of the Intensity BUT the low standard required for compliance.




17 June 2013

2013 Ed Improved power

intensities:

1. Correlated with actual

power intensities from

average lux

2. Checked with ASHRAE

90.1

A clearer image of Table 15 is shown in this slide.




17 June 2013

As comparison, ASHRAE 90.1 (for prescribed Power Intensities for lighting) is shown. For context:

(a) ASHRAE 90.1 – “Energy Standard for Buildings Except Low Rise Residential Buildings;

(b) ASHRAE 189-1 – “Standard for Design of High Performance Buildings.

ASHRAE 189-1 merely refers to 90.1 for Power Intensities. It however includes prescription for advanced practice such as glare control etc.




17 June 2013

1525-2007 1525-2013 ASHRAE 90.1

Walkway / Car Park 5W/m² 5W/m² 0.5W/ft²

Entrance hall, lobbies 20W/m² 5W/m² 1.3W/ft²

Office, shops, writing 15W/m² 14W/m² 1.5W/ft²

Drawing Office ? W/m² 14W/m² ?? W/ft²

Classrooms, Lecture Theatres ? W/m² 18W/m² 1.4W/ft²

Shops, supermarket 25W/m² 24W/m² 5W/m²

Exacting drawing ? W/m² 40W/m² ?? W/ft²

Restaurants, canteens, cafe 15W/m² 8W/m² 0.9W/ft²

Difference in interpretation of spaces and max allowable

lux level between ASHRAE 90.1 and 1525 accounts for the

difference in Power Intensities.

Refer next slide for correlation between allowable lux level

and Power Intensities.

This is a comparison of the Power Intensities of the MS1525-2007 and the ASHRAE 90.1.

We can conclude that Power Intensities for the 2013 edition is more align to current practice common in industry and is more align with international standards.




17 June 2013

This table shows the practicability of the new Power Intensities Standard against illuminance level prescribed. Example (all using T8 lamps) assuming reasonably competent design:

(a) Average 150 lux can expect Power Intensity of less than 5W/m².

(b) Average 300 lux can expect Power Intensity of less than 10W/m².

(c) Average 500 lux can expect Power Intensity of less than 17W/m².



17 Draft MS1525 Ed 2013; Exterior Building

17 June 2013

The lighting power load for

external car parks, drive-ways,

pedestrian malls, landscape

areas, shall not exceed 5

W/m2. The area shall be the

net site area excluding the

built-up area.

Whilst the 2007 edition prescribe a simple 5W/m², the 2013 edition allows for 2 types of exteriors.



18 Conclusion

17 June 2013

Conclusion – Higher Standard of E.E. for Lighting

1. Min. Safety Standard has precedence over E.E.

2. Correlation of CRI (which is a health issue) with lamp efficiency

(primarily to address issues of SSL)

3. Previous edition prescribe Power Intensities which are too “low”.

Draft 2013 edition sets higher standard of EE. which is already

industry norm and to align with international practice.

4. Ballast loss are also set to higher standards to take into account

current development in industry.

Concluding, we expect that the new standards and benchmark set by the 2013 edition will drive higher standards of design, erection and equipment for energy efficient buildings.
