Green Buildings through Green Mark® Certification

What is a green building? Water Efficiency Managing water usage by reducing waste Environmental Protection Transportation accessibility, green areas Indoor Environmental Quality High-level comfort through temperature, humidity and lighting control Energy Efficiency Using less energy by providing the same level of productivity and comfort

What are the benefits? Environmental Reduce the impact of natural resources consumption Health & Safety Economic Enhance occupant comfort and health Improve your bottom line Community Minimize strain on local infrastructure and improve quality of life

Global trends of green buildings Green Building councils around the world Increasing interest in green buildings in Thailand is pushing for the development of a Green Building Council in the Kingdom

How to make your building green? Building & Construction Authority of Singapore launched the Green Mark® certification scheme: Point-based assessment to rate buildings on their environmental impact and performance Voluntary program for new and existing private developments Objectives: Promote awareness and recognition Identify best practices in development, design, construction, management and maintenance in buildings

Green Mark 5 Assessment Criteria -Criteria covers global areas of concern similar to comparable programs in US, UK and Australia. -Energy, water, project development and construction, indoor environmental quality -Environmental innovations adopted for buildings is also Considered.

Basis for Green Mark® Award The certified project must meet minimum total points for the specific rating, and pre-requisite criteria.

Case Study: Schneider Electric’s industrial building in Bangpoo

Demonstrating significant energy savings in Schneider Electric’s buildings In 2005, Schneider Electric Thailand decided to undertake an energy reduction program in its industrial building in Bangpoo.

First step to success: energy consumption monitoring The basis of a successful energy efficiency program is to implement an Energy Management System. PowerLogic® power monitors were installed at node points to survey the electricity consumption. Real time data logging and reporting was made through a specialized System Management Software. Investment: 1.5 MTHB Savings: 2 MTHB / year* Payback: 9 months* * During the first year of implementation

Air-Conditioning Optimization and Control Turn on period of the air-conditioning was optimized in the buildings through control boxes with integrated Programmable Logic Controllers. Over-sized A/C units were replaced as per actual room requirements. Staff awareness promotion through strategic communication was made. Investment: 158.5 kTHB Savings: 122.6 kTHB / year Payback: 16 months

Water Pump Control Investment: 167 kTHB Savings: 57 kTHB / year A Variable Speed Drive (VSD) was installed at the cool water pump for the chiller system. Investment: 167 kTHB Savings: 57 kTHB / year Payback: 2.9 years

Cooling System Optimization Refrigerant in the air-conditioning was replaced from R22 to hydrocarbon which has a higher cooling capacity. An evaporative pre-cooling media was integrated to the existing condensing unit at the point of entry of the air. Preventive maintenance was scheduled on the condensing units according to the readings on the power monitoring system. specially-impregnated cellulose matrix, CeLPad,,, the air is cooled down and humidified. Investment: 423.5 kTHB Savings: 488.3 kTHB / year Payback: 10 months

Results: significant energy savings! 25.6 % energy savings since 2006 236 MWh saved every year, the equivalent of 142 tons of CO2 2005 2006 2007 2008 2009 2010 2011 kWh / head / day 5 10 15 20 25 30 Electricity Consumption Indicator

How to begin?

Energy efficiency The quickest and most profitable diet to save money & the planet! Measure 1. Energy Audit & Metering Monitor Fix the basics 2. Low consumption devices Power quality Power reliability 4. Monitoring and consulting services Automate We are the leader in active energy efficiency: The market In terms of energy, one unit saved at home equals three units saved at the power plant => crucial in the context of climate change. Source: International Energy Outlook 2007 – US Department of Energy (DOE) Evaluate your household’s energy efficiency. Measure You have to measure to see where you are and what you want to achieve => need to know where you consume the most Energy meters Power quality meters 2. Use efficient devices Low consumption devices: light bulbs, heating regulators, etc. Insulation material Power quality Power reliability 3. Automate It’s good to have low consumption devices, but that doesn’t mean you have to leave them on all day! Human beings are lazy. Good resolutions to shut off heaters and lights when you leave a room or office tend to fade away when the effort infringes on comfort => hence the need for automation Building Management Systems Lighting Control Systems Motor control systems Home control systems Variable speed drives 4. Monitor and improve If you never maintain your car, it will consume more and more gas. The same for your electrical installation. To ensure that the results achieved are here to stay and that your new installation is profitable and sustainable: Energy management software Remote monitoring systems => Active energy efficiency 3.
