Abstract Energy flow analysis methods, particularly as implemented using the finite element method, are useful as design techniques for high frequency structural-acoustic applications. In this paper, the derivation of energy flow analysis techniques are summarized. Particular attention is given to the specification of joint models for situations where there is a discontinuity in either geometric properties or material properties. The finite element formulation of this approach is also summarized. A case study is included to illustrate the utility of the method as a design technique.

Strategic selection of glazing, its window-to-wall ratio, and wall thickness of building reduce the energy consumption in the built environment. This paper presents the experimental results of solar optical properties of five glasses: clear, tinted bronze, tinted green, bronze reflective, and polymer dispersed liquid crystal glasses. Laterite room models were modeled with four different thicknesses and four different glasses using Design Builder, and thermal simulation tests were carried out using Energy Plus. The energy savings and carbon emission mitigation prospective of a building’s glazing variety, window-to-wall ratio (WWR), and wall thickness were investigated. The results revealed that among the five window glasses studied, the polymer dispersed liquid crystal glazing window (PDLCGW) was found to be the most energy-efficient for low heat gain in laterite rooms. The laterite room with 0.23 m wall thickness and 40% PDLCGW WWR reduced 18.9% heat gain in comparison with the laterite room with 0.23 m wall thickness and 40% clear glass WWR. The laterite room of 0.23 m wall thickness with PDLCGW glazing of 40% WWR enhanced cooling cost savings up to USD 31.9 compared to the laterite room of 0.08 m wall thickness with 40% PDLCGW. The laterite room of 0.23 m wall thickness with PDLCGW glazing of 40% WWR also showed improved carbon mitigation of 516 kg of CO2/year compared to the 0.23 m wall thickness laterite room of 40% WWR with clear glass glazing. The results also showed that the laterite room with 0.23 m wall thickness and 100% clear glass WWR increased heat gain by 28.2% in comparison with the laterite room with 0.23 m wall thickness and 20% clear glass WWR. The results of this article are essential for the strategic design of buildings for energy saving and emission reduction.

Nowadays, rural power supply in China plays an important role in restricting the economic development and improvement of residential living standards. In this study, an interval full-infinite programming rural energy model (IFIP-REM) was developed for supporting distributed energy system (DES) optimal design under uncertainties in rural areas. By affecting the upper and lower bounds of the interval by complex and variable external conditions, IFIP-REM could simulate the influence of external systems. To validate the model, a real case study of DES optimal design in Guanzhong, a rural area of China, was tested and aimed to minimize system cost and constraints of resources, energy supply reliability, and carbon emission mitigation. The data revealed generation of reasonable optimization schemes to obtain interval solutions of IFIP-REM. Compared to centralized energy system (CES), DES reduced electricity purchasing of the municipal grid by 47.5% and extended carbon emission of both upper and lower bounds to [17.13, 44.51] % and [12.42, 36.02] %, respectively. Overall, the proposed model could help managers make decisions of DES optimal design by coordinating conflicts among economic cost, system efficiency, and carbon emission mitigation.

This study is an appraisal of North–South trade and environmental debate on the context of ‘carbon leakage hypothesis’. This article attempts to quantify the CO2 emissions embodied in the bilateral trade between India and the United Kingdom (hereafter mentioned as the UK) using an input–output model-based analysis for the year 2015. It further proposes a hypothetical situation of no trade between India and UK in order to calculate and analyse the contribution of this bilateral trade in global CO2 emissions. The results from this study confirm the possibility of ‘carbon leakage’ from Indian commodity production sectors and find that among two trade partners, the UK is able to avoid more carbon emissions than India through trade which helps the UK to reach their carbon emission mitigation targets. On the average, manufacturing of commodities in India those are to be exported to the UK generates 1.053 kilo-tonnes of CO2 emission per million dollars of export annually and manufacturing of commodities in the UK which are imported to India generates only 0.141 kilo-tonnes of CO2 emission per million dollars of import from the UK annually for the years 2011, 2013 and 2015. This is because of the proportionately higher consumption of more emission-intensive energy items, like coal, and coal products by India in industrial production than the UK. At the end of the article, this study proposes a few suggestions to ensure a decent level of emission imbalance in the trade flows for the anticipation of increasing India–UK bilateral trade in coming days due to post-BREXIT eventualities to reduce the pressure on the global environment.
