Demand Aggregation as a Strategy for Untapping Buildings’ Energy Renovation Potential: Diagnosis and Prioritization Methodology and Case Study from the Basque Country

Energy renovation of post-World War II private multifamily residential buildings has been identified to have a great deal of energy-saving potential but faces a great challenge across Europe, and especially in South Europe, due to fragmented property structures and longer return periods in energy efficiency investments. However, there is great deal of potential in activating demand aggregation in areas with homogeneous typologies. Local authorities play a key role in leading district-scale renovation but lack adequate methods for analysing and prioritizing areas from an integrated perspective, including social aspects. The methodology presented in this paper aims to support local authorities by providing a tool for the diagnosis and prioritization of homogeneous groups of residential buildings to address their renovation based on an analysis of their needs and opportunity factors. First, the methodology sets the universe of analysis; second, based on indicators, it provides comparative information within the municipality, which leads to a prioritization of areas for building renovations according to the state of the building and to the socio-economic profile of the residents; lastly, a detailed diagnosis of selected groups is performed, providing information to design the Renovation Action Plans accordingly. The application of the methodology in Basauri is presented in this paper.

Demand for Local Renewable Energy Systems: Evidence from North and Middle Andamans

Energy has an innate anthropogenic (human) dimension. Human beings are central to the theme of energy generation and its final consumption. Energy generation and its distribution as a resource governs every aspect of human life on a daily basis. This element necessitates critical understanding of demand aggregation and profiling across socio-cultural systems. The requirement of energy in terms of quantity and quality is emphatically embedded in the socio-cultural ethos of an end-user, the socio-cultural setting of which one is a part. Understanding this aspect is critical for scheduling the supply of energy. Policy issues related to demand side management arise from lack of understanding of behavioural issues of consumers. It stems from community alienation, in planning for generation, transmission and distribution of power. Any techno-economic mega system for power generation is embedded in local socio-cultural systems that comprise all beneficiaries, close or remote. The rural energy landscape needs to be located in different geo-climatic zones and physiographic (physical attributes of landforms such as plateaus, plains, hills, valleys, deserts, islands, etc.) divisions. The study provides an empirical approach for rural energy demand aggregation, drawn from specific socio-cultural system in India.

A DEMAND AGGREGATION APPROACH FOR INVENTORY CONTROL IN TWO ECHELON SUPPLY CHAIN FOR MULTI-PRODUCTS

Demand aggregation is an important concept for controlling inventory in supply chain under uncertain demand. In this concept demand of two or more regions are aggregated, as a result the demand uncertainty is reduced. This concept is very much useful to reduce the safety stocks and it reduces the variability in demand. In this study a demand aggregation model is produced for three different typesof products in two echelon supply chain.This study represents a mathematical model for demand aggregation for different types of product and it provides optimum inventory policy (reorder point, ordering quantity).
