Interview with Clay Nesler, Johnson Controls 

We continue our series of interviews with the founding members of APUEA. In the first issue of the APUEA  Magazine in 2020, we are happy to share a conversation with Clay Nesler, vice president of global sustainability and regulatory affairs at Johnson Controls. During our conversation, we talked about strategies, geographical focus, trends of energy efficiency investment, technology, and more.

Maximizing the benefits of thermal energy storages in district cooling networks with optimization algorithms
and artificial intelligence

For District Cooling Networks a Thermal Energy Storage (TES), like chilled water storage or ice storage, is regularly mentioned as a way to improve safety and generate operational savings, but these potential savings could be only achieved if the TES is well designed and perfectly managed.

Setting the UPS standard - the ABB DPA 250 S4  

In 2018, ABB launched its new modular uninterruptible power supply (UPS) – the DPA 250 S4. This UPS embodies, in one product, many of the technological innovations that ABB, a pioneer in the UPS business, has introduced to the market in recent times. The DPA 250 S4 will set the trend in UPS technology for years to come so it is worthwhile to explore what advantages its capabilities can bring to users.

Supporting the lifecycle of energy infrastructures with
Smart O&M   

In the era of industry 4.0, most energy projects in Asia still enter commercial operation without a maintenance system in place. Instead, the operation and maintenance (O&M) team, already busy with start-up issues, struggles to gather technical documentation, to define paper-based procedures, and when time allows, years later, to implement a computerized system. Experience shows that the earlier maintenance is taken into account, the better the results in terms of lifecycle cost. Maintenance should be specifically addressed from the design stage and throughout construction until the plant is finally handed over to the O&M team.

Make Building Heating More Energy Efficient
by Artificial Intelligence   

Better utilization of existing automation systems and hardware improves energy efficiency of district heating by improved process and indoor temperature control. More stable indoor temperature reduces the amount of high and low-temperature periods decreasing overheating and improving residential comfort. Furthermore, well-controlled indoor temperature and heating without sacrificing comfort. LEANHEAT AI applies machine learning and optimization to make district heating more efficient. It utilizes the data that can be achieved from a standard PLC controlled district heating substation, weather forecast (including solar radiation, temperature, wind) and indoor temperature measurements.

The Potential of District Energy and Waste Heat Recovery
in Asia Pacific 

We experience increased urbanization world-wide. This means that there will be an increasing number of densely populated areas where people live, work, and consume energy. It is known that there is a heat density problem in urban areas, with higher temperatures than the surrounding areas. Heat is generated by people using infrastructures like subway and wastewater systems. Heat is generated by data centers and heat is generated by the service sector like hospitals, schools, and offices. There is available heat in cities and it could be put into use.

Renewables in Cities 2019 Global Status Report 

Cities are directly responsible for around two-thirds of global final energy use as well as for significant indirect consumption of energy that is embodied in materials, products and other goods. Due largely to this energy use, cities account for an estimated 75% of global carbon dioxide (CO2 ) emissions. Electricity accounts for only 17% of worldwide final energy demand, so there is an urgent need to decarbonize heating, cooling and transport, which together account for the remaining 83% of energy demand.

Editorial by the Executive Director

Dear APUEA Network,

In the light of the COVID-19 pandemic, we see energy consumption drop across sectors in affected areas, and urban pollution reduction is visible in many cities. Besides the negative health effects of the virus, the global economy is facing challenges. Even though the negative effects of the pandemic are significant, rapid change in public behavior and resolute governments gives hope for other global challenges to be fought – not at the least, climate change. We are starting to see that joint efforts by governments and the public for the better good can generate great results.
The urban population in Asia-Pacific exceeded 2.3 billion in 2019, corresponding to 54 percent of the urban population globally. The urban population in the region is expected to rise to more than 2.8 billion in 2030 and reach almost 3.5 billion by 2050. This increase is equal to four new Tokyo-sized cities every year and will require great efforts by local governments to develop sustainable urban energy and livable cities. I'm confident that this growth can be sustainable as long as there is political and public will and sufficient insights into the available urban energy solutions are provided. APUEA is dedicated to support this development and offer knowledge exchange and transfer to cities across the region.

About the Asia Pacific Urban Energy Association (APUEA)

The APUEA is an initiative of the International Institute for Energy Conservation (IIEC), a not-for-profit organization that has been promoting sustainable energy and environmental solutions in developing and emerging economies–including in the rapidly developing urban sector–for more than three decades. The APUEA platform promotes public and private sector collaboration to develop sustainable urban energy systems that support livable cities across the Asia Pacific region. The Association's online portal serves as an information hub to support city policymakers, program managers, and other stakeholders in the design, development, and implementation of sustainable urban energy systems. Through this portal, APUEA events, and continuous outreach to its members, the Association shares international and regional best practices for planning and implementing sustainable urban energy systems–including policies and regulations, business models, and technologies for implementing district heating and cooling, smart grids, energy efficiency improvements, and renewable energy systems.
