“Prediction of discomfort glare from windows under tropical skies” accepted for publication in the Journal of Building and Environment
IEN has had the following manuscript accepted for publication in the Journal of Building and Environment, "Prediction of discomfort glare from windows under tropical skies"
Journal: Building and Environment
Special Issue: Advances in daylighting and visual comfort research.
Publication Date: 15 February 2017
Discomfort glare is common problem in modern buildings that employ highly-glazed façades. Glare not only has negative impacts on occupant comfort but can also increase energy use in buildings. Yet a robust discomfort glare metric, particularly with regards to daylight, has proven elusive. The Unified Glare Probability (UGP), developed using 493 surveys under clear skies in Brisbane, Australia, shows promise as useful tool for estimating glare from
windows. This investigation attempts to validate the UGP using a similarly large number of surveys under different sky conditions, different building types and demographics in the tropical climate of Kuala Lumpur, Malaysia.
The study uses a similar methodology to the initial investigation of the UGP, using a combination of luminance mapping with a post-occupancy evaluation (POE) questionnaire on discomfort glare. A total of 341 surveys were collected from six buildings; three green-rated and three regular office buildings. Hypothesis testing of the luminance data collected in these buildings indicate that the ratio of window to background luminances are a more sensitive measure of occupant discomfort than ratios of window to task luminances.
The results for the UGP show agreement in predicting discomfort from windows between both data sets using regression analysis. A simple hypothesis test showed discomfort was accurately predicted by the old UGP model for 69% of new surveys. The agreement between the two data sets for window glare enabled them to be combined into one massive data set of 813 surveys to update the UGP. The updated metric uses a logistic curve in place of the
original linear transformation of the Unified Glare Rating (UGR) to prevent illogical values of probability being obtained from the metric.

Zero Energy Mass Customised Housing
IEN has agreed to sponsor and speak (tbc) at the 5th International Zero Energy Mass Customised Housing 2016 (ZEMCH 2016) conference. University of Kuala Lumpur (UniKL) has teamed up with University of Brighton, University of Southampton, University of Melbourne and two more to organise and host this conference. The Master of Green Energy Efficient Building (MGEEB) students, which IEN has helped to lecture and supervise, will be among the many presenters.
Daylight for Tropical Offices
A comprehensive write-up with several case studies of how daylight can be implemented in office buildings in the tropics. The article shows how daylight systems can be designed to provide the building occupants with a pleasant environment lit by diffuse natural light, which is very different from the typical facades where occupants suffer from glare and overheating. Another important issue addressed by the article is daylight responsive general lighting controls and the benefits of task lighting. Several of the case studies, such as the GEO building, ST Diamond building and the KKR2 building, are reference projects of IEN Consultants. Enjoy the read!
"Power to Change" movie
IEN is helping MESYM to do a free screening of the documentary, Power to Change, is about the ongoing energy revolution in Germany. It's a film about a great vision — and the people turning it into reality: the rebels of our day. The future of world energy lies in decentralised, clean supplies stemming 100% from renewable sources. That is the message of the documentary Power to Change — The energy rebellion.
After the screening we will have a Skype call with the movie director Carl A. Fechner
Case for Building Simulation
IEN was invited to give a talk about building computer simulation and how simulation can benefit the building design process by informed decision-making. The presentation makes a compelling case for using building simulation, both to optimise the building performance (energy, daylight, rainwater harvesting etc) and also to minimise over-design (for example, over-sizing of the cooling system). As such, building simulation helps to decrease both the CAPEX and OPEX of building projects.

Air Quality (PM2.5) readings for KL
IEN has purchase two air quality readers that are place indoors and outdoors. Both real-time readings are made available to everybody, so we all can know the current severity of haze in Kuala Lumpur. Just install the free Breathing Space app on your smart phone and scan the QR codes. The air quality device reads PM2.5, PM10 and calculates the air quality index (AQI). See attached presentation for more details.
Anthropogenic Mass Extinction
IEN wrote this article about how human activity has a profound effect on the World we live in for GreenPlus Magazine. The points raised in the article are also referenced in the IEN brochure, namely, in the 'Message from the CEO':
Human influence on Earth and its eco-systems is now so profound that scientists tell us we have entered a new geological age called the Anthropocene, where humanity's impacts will be visible millions of years into the future. This is astounding - and hardly sustainable!
To lessen the human (anthropogenic) environmental impact and our all important effort to avoid irreversible catastrophic climate change, the built environment plays a key role. Not only does forty percent of the World's resource consumption relate to the built environment, but this is also the sector with the biggest and cheapest greenhouse gas emission reduction potential. Moreover, people spend about ninety percent of their time indoors, so let us make our time spent on this Earth worthwhile by designing buildings and cities that cater better to human needs as well as being environmentally friendly.
There's a common misconception that it is expensive to build energy efficient, green and healthy buildings. The truth is quite the opposite, as proven by our company's vast track-record. And the case becomes even more compelling when factoring in human health and long term effects of climate change.
The choice is clear: Build green!

MENARA KERJA RAYA (formerly known as KKR2) awarded GBI Platinum Final certificate
Completed in 2015, this 37-Storey high rise government owned and occupied Menara Kerja Raya recently became only the 2nd new building, in the non-residential category to be awarded the prestigious Green Building Index (GBI) Platinum final certification. The other building being Energy Commission’s Diamond Building in Putrajaya.
Standing at approximately 175meters tall, this tower houses a total of 1,600 staff from the Ministry of Works as well as Public Works Department (Jabatan Kerja Raya) Malaysia over 53,000 square meters of building floor area. The offices of the Minister of Works as well as the Director General and Deputy Director General of the Public Works Department have also been moved to this tower.
Achieving GBI Platinum final certification is no simple feat for any building. The building incorporates many features to reduce energy consumption, improve occupant comfort, reduce impact of material usage as well as make use of less treated potable water.
Although the tower design incorporates floor to ceiling glazed facades which are exposed to the East & West orientations, it manages to reduce solar heat gain by employing triple pane insulated low-E glazing. Coupled with efficient lighting design with a low 8W/m2
lighting power density and automated control which effectively turns of 40% of the office lights during daytime, as well as air conditioning system that is able to reduce fan power down by more than 50% on reduced load days, the building achieves a very respectable BEI (Building Energy Intensity) of about 90kWH/m2
year, which is about 60% lower than buildings that are design to merely meet MS 1525 guidelines. This saves the Government approximately RM2.5mil per year in electricity charges at the current energy rates.
Overall daylighting strategy played a huge role in creating a unique and much comfortable indoor environment in this building. Custom perforated venetian blinds, low height workstation and glass partitions for private offices and discussion rooms all work together to create an open well daylit office space that is so much more inviting and conducive to the occupants. With these strategies, we have verified that usable daylight levels are achieved up to 6meters from the facade, which allows the automatic shut off of lights over these areas.
This tower is also one of the first building to incorporate a waste water treatment system that is able to treat the greywater from wash basins, floor traps and ablution to be reused within the building for toilet flushing and landscape irrigation. A 400 cubic meter underground rainwater harvesting tank captures plenty of rainwater to be used for similar purposes in the building when there is rainfall. These strategies and the use of low flow fixtures at toilets and ablution, as well as significantly lower cooling load resulting in lower cooling tower water usage has managed to reduce water consumption per square meter floor area by 70% compared to another neighbouring JKR office tower.
Menara Kerja Raya was officially launched on the 7th of December 2016 by Prime Minister Datuk Seri Najib Tun Razak. The Launch was covered by The Star ( click to read the article

New Zealand Academy of Applied Research (NZAAR)
IEN has been invited to give the keynote speech at the NZAAR international even series on "Natural and Built Environment, Cities, Sustainability, and Advanced Engineering". The title of the keynote speech is "Reclaiming our streets". The talk takes basis in the fact that a common denominator in the "Most Livable Cities" competition is that the winning cities deliberately have improved the cityscape for pedestrians and cyclists and deliberately have reduced car-based transport. Is such a development feasible in tropical Asian cities that are both rapidly expanding and have a hot and humid climate? The answer is yes, but it will not be easy. The talk explores some of the barriers to reclaiming the streets, which includes human/cultural barriers. The talk also points to some of the technical/planning solutions that make reclaiming the streets possible and when gives added benefits, not just in terms of making the city more livable, but also with respect to the socio-economic upside, particularly with respect to improving public health.

4th International Building Control Conference IBCC
IEN has been invited to present two papers:
"Practicality and Performance of Daylight Trough in the Tropics"
A case study paper on the daylight performance of the pioneering daylight trough that was fitted in MK Block D. The daylight trough is capable of daylit the office space as deep as 6 meters sufficiently at its peak. With an impressive lighting power density of 1.90W/m2, the daylight trough design saves 39.2% of lighting energy over conventional lighting system. This paper further elaborates the practicality of working with such a system, including cost implication, design challenges and contractual difficulties.
"Office Occupants' Mood and Preference of Task Ambient Lighting in the Tropics"
The paper reaffirms previous findings that the usage of task light has increased subjects' lighting satisfaction with paper work and overall mood significantly. Despite only 30% of recorded illuminance within MS1525 range, the increased in lighting controllability complements the wide range of illuminance preference among the subjets. A significant finding is also that lighting satisfaction is not correlated to illuminance level but correlated to the variation of illuminance level throughout the day, which shows the combination of task light and ambient daylight to be the most appropriate lighting system for the office space in the Tropics.

IEN has been invited to present the paper:
Discomfort Glare in Energy Efficient Buildings: A Case Study in the Malaysian Context
Discomfort glare is a well known problem within the built environment. However very little research has been conducted on discomfort glare in purely tropical environments. This preliminary investigation focussed on the ST Diamond Building located in Putrajaya, Malaysia. In total, 68 surveys were collected during the investigation. The surveys consisted of a questionnaire as well as luminance mapping of the occupant’s visual environment.
Luminance maps were analysed via Evalglare to calculate the Daylight Glare Probability(DGP) and Unified Glare Probability (UGP). It was discovered that occupants were more tolerant to potential glare than expected, most likely due to the high luminance uniformity from innovative daylighting strategies employed in the building. Occupant position in relation to the window had a significant effect on both glare indices tested. The UGP was much better at predicting glare for occupants further away from the façade.
Type 2 (or false-negative) analysis was conducted on both glare indices. A false-negative result occurs when the survey response was “uncomfortable” but the index being tested predicted “comfortable”. The method showed promising results for UGP in the case of the ST Diamond Building, with an index threshold of 0.35 required to achieve 95% accuracy in predicted comfort. The DGP required an index threshold of 0.07, which may be impractical to implement in lighting design.

IEN has the pleasure of taking part in the 1st Earthship building being built in Malaysia
IEN has the pleasure of taking part in the 1st Earthship building being built in Malaysia. We took part in a design brainstorming session, as well as in the volunteering for the construction of the Earthship, which consists of two residential dome-shaped homes and one community hall for up to 50 people; both of which is built for the Orang Asli near Kampung Chennah (about 2 hours drive into the jungle east of Kuala Lumpur). The project should be completed before the end of 2015.
The Earthship concept is very appealing with respect to sustainability. An Earthship - like a spaceship - seeks to be fully self-sufficient with energy, water and food. Moreover, Earthships are often built by recycled materials like use car tyres, used glass bottles, used rice-sacks filled with soil etc. In other ways, Earthships really push the sustainable agenda. Read more about the Earthship concept here (link
The project is lead by Ruben ("Build for tomorrow") and in collaboration with Arkitrek. If you want to volunteer or just want to follow the progress of the Earthship go here: https://www.facebook.com/earthshipmalaysia

IEN attending "Industry Speaks" on the discussion "Does Cheap Oil Weaken the Case for Energy Efficiency?"
Download IEN Consultant's input to the event "Does Cheap Oil Weaken the Case for Energy Efficiency?" The answer is a resounding "No", because fossil fuels are significantly underpriced in Malaysia as their true cost to society (pollution and adverse health effects) are not captured. In fact, even if oil was free of charge, one would still have to pay a higher price at the petrol station that one does today from the negative costs to society.

Talk: "Finding solutions while bound by constraints"
IEN has been invited to give an inspirational talk about how we find workable and sustainable solutions for our clients within the framework of the project at hand, which always have many constraints. Apart from the typical budgetary constraint (i.e. incurring additional cost), we also face physical constraints - particularly with respect to building retrofit projects and what modifications are physically possible - as well as human constraints / willingness to try new building solutions that people are unfamiliar with. We are giving the talk to the software developers at Dong Energy IT, who also are bound by a number of constraints in their daily work.

DONG Energy visit
IEN Consultants visited Dong Energy, the biggest Danish power provider with a very strong environmental profile having won the 'Environmental and Corporate Sustainability' prize under the European Business Award (2013). Dong Energy is rapidly shifting away from fossil fuels to renewable energy power, so by year 2040 renewable energy accounts for 80% of their power production. Already by year 2020, the CO2 emissions per kWh will have dropped to 0.26 kg CO2 / kWh. For comparison, peninsula Malaysia TNBs emissions are currently at 0.64 kg CO2 / kWh and increasing (some say it is at 0.80 kg CO2 / kWh already).
Moreover, Dong Energy's IT department in Malaysia works on sustainable demand side solutions, including the so-called PowerHub project, which essentially is peak power demand management for big power consuming customers. Flexible demand-side management is a key to increase the share of renewable energy production in the power supply, as these sources often fluctuate (solar, wind, waves, tidal).
The visit to Dong Energy was very inspirational, as Dong Energy is taking the lead and showing the way forward for other power utilities to follow.

As part of our annual company trip, IEN made an excursion to the sustainable Green School in Bali. We found this international school is highly inspiring - not only because it is built entirely from locally grown bamboo, but also because sustainability forms an integral part of the curriculum. For example, the students grow their own rice and vegetables on the school grounds - and most of the energy is produced onsite with solar panels and mini-hydro (vortex hydro). In order to render our support to this meaningful institution, IEN Consultants gave a donation to the Balinese Scholarship Fund, which allows the local students to make up about 10% of the student body. In return, we had our company logo and name carved in the bamboo of the main building of the school (see pictures).

Solar Heliostat for Daylighting
IEN is helping the development of this innovative product, which can redirect sunlight to light up dim rooms. This small portable sun-tracking mirror-wielding device, SunnyBot, redirects 7,000 lumens of sunlight to the location of your choice (equivalent to a single 500W halogen lamp). The reflective range of the device is up to 200 metres away, with an accuracy error margin of as little as 0.1 meter over 30 meters. IEN has purchased on SunnyBok and is hereby supporting Solenica to raise £200,000 via Kickstarter to step up to industrial manufacturing so it can bring the device market.

Two Yike Bikes for the IEN Office
Now the IEN staff can both Build Green and Drive Clean!
Two Yike Bikes for the office. The 100% electric bicycles are available for staff to use for their daily commute to the office. The bikes are foldable and portable and hence easily combine with public transport. Moreover, they do not add to the congestion and air pollution of the city. The energy consumption of a Yike Bike is only 2.3% compared to an average car, and the associated CO2 emission of the Yike Bike is only 6% compared to a car. The electricity consumption for a full 10 km charge only amounts to only 0.223 kWh, or just 8 sen (Malaysian cents). And with the Yike Bike no time or money is wasted on parking. IEN Consultants believes that electric vehicles are part of the solution to achieve a sustainable society. Hence, with the purchase of the two Yike Bikes, we are happy to extend our slogan to "Build green - Drive clean".
