Session 1.3: Heating and Cooling for Buildings in Cities

May 22nd, 2019

The buildings sector is responsible for more than one-third of global final energy consumption. Presenters in this session highlighted the essential role of heating and cooling in the energy profile of cities and discussed technologies, systems, and strategies for moving toward low-carbon space-conditioning of cities. Some of the topics covered included energy-efficient appliances, LED lighting, smart residential and commercial buildings technologies, health and safety impacts, and energy conservation building codes.

Smart Low-Carbon District Heating and Cooling for Seoul
Yunsoung Kim, Research Fellow, Green Energy Strategy Institute

Seoul has a high population density and limited available land, which is a disadvantage for large-scale development of solar PV and wind power. This presentation focused on a smart district energy system that can meet the heat and electricity demand by using co-generation, and multiple regional energy resources with less emission and energy consumption. It also showed some cases of the utilization of temperature differences for energy transfer in district heating; highlighted the potential benefits of smart low carbon district energy system; and discussed what policies are needed to realize the potential benefits.

Waste is Cool! How 'First Mile' Waste Solutions can Cool the Smart Cities of the Future
Aditya Sharma, Senior VP, BOSON ENERGY

70% of world’s waste today is dumped or landfilled without energy recovery. However, done right, waste is one of few "fuels" produced everywhere, and perhaps surprisingly, suitable for sustainable cooling. This presentation provided an overview of the next generation of efficient small-scale solutions converting local mixed waste into clean power, heat or greenhouse-gas-free thermal cooling for direct local use. Zero waste, no toxic ash residues.

Impact on Cooling Demand with Building Efficiency Programme
Smita Kudarikar, General Manager, Maharashtra Energy Development Agency

The Energy Conservation Building Code (ECBC) is an initiative taken by the Government of India to promote energy efficiency in the commercial building sector. The updated version of the code was launched in June 2017. This presentation highlighted the features of the Maharashtra Energy Development Agency building, which is designed to be climate responsive, sustainable and comply with the super ECBC norms, without compromising on the aesthetics and functionality. This has reduced cooling requirement by 30-40% and reduced energy consumption by one-third (~35%).

Demand Response as a Tool to Enhance the Urban Energy System Efficiency
Yang Liu, Senior Fellow, National University of Singapore

This presentation shared insights from a demand response scheme for industrial customers in Singapore. The case study illustrated the benefits of demand response by reducing end users electricity bills, improving the asset utilization rate, and increasing the efficiency of the whole electricity system. Drawing on Singapore's experience, many Asian countries can glean lessons to provide effective financial and incentive mechanisms to reflect the value of demand response.
