Benefits of Energy Efficient Glass
GUARDIAN CONFIDENTIAL 3
2016 is the hottest year on record – third year in a row!
In most countries buildings account for approximately 50% of energy consumption
In the GCC region, approximately 70% of energy consumption goes to cooling, 25% of which is due to windows
Windows with high energy efficient coated glass can reduce energy consumption by around 35%
More Benefits of Energy Efficient Glass
4 GUARDIAN CONFIDENTIAL
A window with clear glass will let in more than 70% of solar radiated heat
The same window with a modern energy efficient coating can reduce that to less than 25%
The amount of visible light is also a contributing factor; • too much light will let in more heat, increasing A/C loads • too little light means electric lights will always be switched on consuming more electricity
Potential for Energy Savings

If all new buildings planned in KSA for 2016 had clear glass their energy demand would be approximately 1 GW
Having code compliant windows would reduce that by 100 MW or 10%
In 10 years that would equal 1 GW – equal to the capacity of the Ha’il 2 power plant in KSA
Besides the cost savings (62 million MMBtu of natural gas), 3 million MT of greenhouse
gasses will be saved every year.
Energy Codes Compliance & Enforcement
6 GUARDIAN CONFIDENTIAL
All GCC and Middle East countries have adopted energy codes for residential and commercial buildings
Globally code compliance can be mandatory, voluntary or a mixed system
Countries where code compliance is mandatory are more effective •Developers face pressure to reduce up-front costs, even for energy saving products would reduce running costs especially where the tenant pays for the electricity costs
Energy Codes Compliance & Enforcement
7 GUARDIAN CONFIDENTIAL
Enforcement is always a challenge, particularly due to the following:
Lack of Training Enforcement officials and
architects need to be sufficiently trained in all aspects of the code
for a good understanding
Lack of Information
It is difficult to determine if the product will perform as stated since
the coatings are virtually invisible, yet perform dramatically differently
Lack of Consequences
In some countries there is little or no provisions to monitor
compliance and/or no penalties or fines enforced
Testing, Certification & Labeling System
8 GUARDIAN CONFIDENTIAL
Countries are increasingly adopting a testing, certification and labeling system to easy code enforcement
UAE (Dubai, Abu Dhabi) are already testing and certifying glass products, and have recently accelerated a labeling system
KSA already implemented a labeling system for white goods, and is building a testing and certification system for glass
Such programs are often run by government agencies, as well as academic institutions
Testing, Certification & Labeling System
9 GUARDIAN CONFIDENTIAL
In addition to code compliance, certification and labeling systems also carry commercial value to the developer
With the rising electricity costs across the GCC energy efficiency is a key driver to property values
Millennials also place greater value in green products than any other consumer group
Labeling is the most effective way to communicate the energy saving value of windows

Analytical Tools
11 GUARDIAN CONFIDENTIAL
•Guardian Glass has developed a set of analytical tools to help educate architects and developers, as well as students, on the energy implications of various glass coatings
The 4 key Components Include:
• Performance Calculator – calculates the energy and aesthetic details of any glass makeup or combination
• BIM Generator – Provides thermal and optical performances of specific building makeups.
• Building Energy Calculator – calculates specific building energy consumption, cost and financial payback period
• Glass Visualizer – helps architects and designers see what the building will look like with different glass products under various conditions
Analytical Tools – Product Payback

Above Code Systems • There is growing support for a voluntary code system that goes
above and beyond the mandatory building code • Examples include:
• Leadership in Environmental and Energy Design (LEED) • Pearl System (Abu Dhabi)
• Such systems tend to carry more prestige and brand value
