Cooling homes, offices and cities sustainably and affordably is one of the biggest challenges facing Asia, as its population aspires to more comfortable living and working conditions. Demand for space cooling is growing fast and will this will result in a significant increase in global energy consumption (and greenhouse gas emissions) unless effective policies and efficient technologies are adopted quickly and efficiently. While many discussions start with the goal of reducing the energy used for cooling equipment, long-term, systemic benefits can also be achieved through strategies that reduce the need for space cooling while still increasing comfort and health benefits. Both opportunities enable multiple benefits such as lower energy bills, fewer electricity capacity constraints and less use of climate-warming refrigerants. This session will explore strategies for space cooling and opportunities for reducing its impact on Asia’s energy system.

Innovative Case for Energy Efficiency: Energy Performance Contracting
Building energy efficiency is strongly linked to control systems, and auxiliary equipment to support proper, efficient cooling of building space. This presentation will discuss the application of energy performance contracting (EPC) to space cooling in buildings. EPC is a form of guaranteed energy savings contract, which enables consumers to realize the technology for space cooling they want and the savings they need. Through EPC contracts, building owners can establish a new baseline and a new benchmark, to help them effectively manage what they spend on space cooling.

A Sustainable 3-Pronged Approach in Energy Management Program Implementation for Office Space Cooling
Identified as the main driver of electricity consumption in offices, space cooling plays a significant role in providing comfort in every office operations. On the average, air-conditioning systems account for more than two thirds (67%) of total building consumption. This presentation will illustrate how Ayala Property Management Corporation set and met a first-year goal to reduce 3.8M kg CO2 equivalent of greenhouse gas emissions among its managed properties with the implementation of a sustainable 3-pronged approach: rolling out best practices, engineering intervention, and organic R&D for cutting edge technologies. This work to improve the efficiency and management of air conditioning energy use in buildings has translated into 21 Philippine Department of Energy Efficiency Awards and 1 ASEAN Award for Energy Management in 2017.

Cut Peak Electricity Demand and GHG Emissions through Innovative Energy Storage!
Energy storage changes the way buildings are cooled, saving money and reducing GHG emissions. Energy storage works with refrigeration equipment to produce cold water or ice, which is then stored in a tank and used to cool buildings during peak hours. This enables the shifting of cooling operations to off-peak hours, cutting peak electricity demand for utilities and reducing GHG emissions. Examples of real installations with quantitative analysis will be used to show how utilities and buildings benefit from using load leveling strategies. This presentation will build a persuasive case showing why energy storage is an integral part of UNEP’s Global District Energy in Cities Initiative, which is being advocated across Asia.

Cost-Effective AI + IoT to Dynamically Optimize Variable Energy Systems
DeJoule, the technology platform of Smart Joules, captures critical operating parameters of central cooling systems in real time, continuously dissects this data to identify sub-optimal operating practices, and drives energy efficient performance by automatically adjusting critical set points based on a menu of optimization algorithms. This cost-effective and smart technology has generated between 15% and 30% annual energy savings in multiple large existing hospitals in India, and is ready for accelerated adoption throughout the developing world where previous building management systems have been unaffordable and ineffective in saving energy. The presentation will include a detailed techno-commercial case study of the deployment of DeJoule in a national energy award- winning Indian hospital, with the aim of encouraging replication of the approach across the region.
