Special Issue Information

Dear Colleagues,

The investigation of energy efficiency in buildings remains a fundamental aspect of addressing the contemporary climatic, economic and social challenges. In recent decades, research has made significant advances, resulting in the development of strategies that enhance indoor comfort while simultaneously reducing energy consumption. Nevertheless, it is not always the case that these solutions entail a reduction in the use of resources. In light of the ongoing expansion of urban areas and the increasingly evident effects of climate change, the pursuit of more efficient and sustainable measures has assumed a heightened urgency. While advances in architectural design, innovative materials and smart technologies have offered promising solutions, further exploration is required in order to ascertain their implementation, scalability and affordability.

This Special Issue aims to collate research that investigates innovative strategies to enhance the energy efficiency of buildings, striking a balance between comfort and sustainability. It encompasses studies that address challenges such as passive system modeling, real-world applications, and studies that promote practical and scientifically sound solutions that are applicable in different contexts.

Topics of interest for publication include, but are not limited to, the following:

  • Passive cooling/heating strategies in buildings.
  • The integration of sustainable and innovative interior conditioning technologies.
  • Integral solutions to reduce energy consumption in buildings through intelligent systems and/or renewable energies.
  • Methods for assessing energy efficiency throughout the life cycle of buildings.
  • The relationship between the reduction in indoor consumption and its impact on outdoor comfort.
  • Active thermal storage systems in buildings.
  • An evaluation of sustainable cooling or heating measures in different climates.
  • Indoor comfort implications of measures applied to a building.

This paper attempts to find alternative ways in which heating, ventilation, air conditioning and refrigeration systems can be made more energy efficient and sustainable at a global level. Eight technologies or solutions that either passively or supplementarily reduce the heating or cooling load required by a structure are detailed. These technologies or solutions were then presented to heating, ventilation, air conditioning and refrigeration industry professionals in New Zealand to determine their viability and further establish market readiness towards integrating new, innovative, and sustainable solutions in New Zealand. A literature review was conducted to establish the performance of the selected solutions and understand their operational principles and the efficiency they provided. Qualitative research and data collected via semi-structured interviews provided the data for assessing the viability of the selected technologies in the New Zealand market. Following a thematic and hybrid-thematic analysis of the data, the technologies were ranked, and suggestions were made to help improve innovation and energy efficiency in the heating, ventilation, air conditioning, and refrigeration industry in New Zealand. Of the technologies selected, airtightness, heat recovery ventilation retrofits, materials and design principles, and photovoltaic hot water heating were identified as the most viable. The New Zealand market was deemed not to be in a good position to adopt new or alternative solutions. The main issues affecting New Zealand’s market readiness to assimilate innovative and energy-efficient solutions are a lack of new technologies, poor standards of education throughout the industry, a lack of regulation, and a lack of government incentives.
