The Low Voltage Direct Current (LVDC) system concept has been growing in the recent times due to its characteristics and advantages like renewable energy source compatibility, more straightforward integration with storage utilities through power electronic converters and distributed loads. This paper presents the energy efficiency performances of a proposed LVDC supply concept and others classical PV chains architectures. A PV source was considered in the studied nanogrids. The notion of Relative Saved Energy (RSE) was introduced to compare the studied PV systems energy performances. The obtained results revealed that the employment of the LVDC chain supply concept is very interesting and the use of DC loads as an alternative to AC loads, when a PV power is generated locally, is more efficient. The installed PV power source in the building should be well sized regarding to the consumed power in order to register a high system RSE.

The Impact

With rapid climate changes in recent years, it has become important as it is necessary to think about a new concept of architecture that respects and considers the environment. To counter these changes, the concept of environmental and green architecture starters' theory has appeared as one of the applications of creative solutions in buildings. Architects then began turning it from a theoretical study on the method of the design of buildings and making them environment-friendly by reducing the consumption of resources to run the building and reduce damage to the environment due to Alanbosat and waste resulting from construction work. Environmental and green architecture does not just reduce the impact on the environment but also supports energy-efficient buildings, which achieves self- sufficiency within the building. It also provides energy production and exploits the optimal way efficiently and with equanimity. This paper aims to: - Highlight the importance of green architecture and sustainability in shape. - Reach a methodology to convert existing buildings into green buildings.

The Cost

Purpose – The purpose of this paper is to identify the factors present in successful energy efficiency investments that might indicate how to resolve the landlord-tenant dilemma in existing and new commercial property. Design/methodology/approach – The paper reviews literature to indicate the importance of energy efficiency in buildings and to explore the barriers to such investments, including problematic landlord-tenant relationships. Such relationships have been investigated by the International Energy Agency, and a similar approach is used here in two case studies in new and existing buildings. These studies explore the nature of landlord-tenant relationships and the importance of policy and standards of building performance. Findings – In neither case did landlord-tenant issues constitute barriers to investments in energy efficiency, however, these investments were made for other reasons than simple cost savings. Construction of new commercial property to Passivhaus standards ensures a high-build quality and a comfortable building with low-energy costs. The added value to tenants may justify the cost of construction. The cost of investments in energy efficient buildings can also be justified by the enhanced reputation of landlords which may be more valuable than a DEC rating. In neither case was the commercial Green Deal felt to be an attractive funding mechanism. Practical implications – Conclusions based on these case studies must be regarded as tentative, so future studies of successful energy efficient buildings should be undertaken to explore the motivation to invest, particularly the relative importance of indirect benefits of energy efficiency. Originality/value – One of the case study buildings is exceptionally energy efficient and is the result of a particularly open and effective contractual relationship. Further study of such cases may suggest a new approach to landlord-tenant problems of energy efficiency, even in refurbishment of existing buildings.

Commercial Buildings consumes a large amount of world’s energy. Energy components comprises of Lighting, Heating, Cooling, Ventilation, water heating etc. To make the building energy efficient, we need to maintain, monitor and apply thermal optimization. Numerous researchers over the world are chipping away at vitality demonstrating and control with a specific end goal to create techniques which will bring about general decrease of vitality utilization. This paper presentstheworkflow of the energy modelling HVAC (heating, ventilation and cooling)systemwhich proved to be the complete solution for low energy buildings.Also the estimation of the thermal load which helps in validation of architectural design for energy efficient buildings.

Alkali Activated

The contribution of building materials’ production to environmental impacts becomes significant in the new energy efficient buildings that are currently built. Among those materials, cement represents a major part of the embodied carbon footprint of buildings. Development of alternatives to traditional Portland cement have emerged over the last decades; however, their environmental assessment over their life cycle have resulted in conflicting results, which give a confusing picture of the strategic path to be followed. This paper focuses on the alkali-activated cement and concrete and points out the variability linked with the choice of energy source for the production of the activators and precursors. A review of existing studies is then performed in order to highlight the main benefits of these alternative cements in terms of reduction of greenhouse gas emissions. Finally, the results presented here highlight further research trends for new cements and concrete.
