AbstractThe article raised issues related to the design and execution of low-energy objects in Polish conditions. Based on the designed single-family house, adapted to the requirements of the National Fund for Environmental Protection and Water Management (“NF40” standard), the tools to assist investment decisions by investors were shown. An economic analysis and a multi-criteria analysis were performed using AHP method which had provided an answer to the question whether it is worthwhile to bear higher investment costs in order to adjust to the standards of energy-efficient buildings that fulfil a minimal energy consumption's requirements contained in Polish law. In addition, the variant of object that had optimal characteristics due to the different preferences of investors was indicated. This paper includes analysis and observations on the attempts to unify that part of the building sector, which so far is considered to be personalized, and objects in accordance with the corresponding idea are designed as “custom-made”.

Design And Construction

Sun is the renewable energy source whose usage exerts influence on architectural design. Facade concepts of energy efficient buildings are developed producing new facade structures and components. Photovoltaic systems, as elements of active solar systems are discussed in the paper and particular attention is paid to building integrated systems, as they influence building appearance. Classification and analyzes of PV systems - materials, supporting systems, coatings and design principles are presented in the paper. The purpose of this paper is discussion on design and construction possibilities for PV integration in envelopes of new and existing buildings. Possibilities for structural variability of envelopes with PV integrated systems are described in the paper. .

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.

Energy Efficient Building

Housing development, as part of the economic development must be supported by energy availability in order to obtain a sustainable growth. One of the approaches to support the renewable energy promotions is designing and building energy efficient housing. However, optimal design of energy efficient buildings is facing two conflicting requirements, namely cost effective consideration and minimum environmental impact. The high costs from energy efficient building such as the Near Zero Energy House (nZEH) is due to high price of materials and equipment used, such as solar panel, insulation and other supporting materials. Indonesia is situated at the equator and received sunlight throughout the year. Nonetheless, this potential has not been fully discovered due to the high cost of the solar generated energy technology for housing. Moreover, this technology is not integrated with the main electricity network. Thus, the objective of this study is to identify the design variables for nZEH that suit the tropical climate condition in Indonesia. Experiments and Case Study are used for the study, and the validated design variables for nZEH, which includes building orientation, PV, fenestration, and passive design, will be the basis for optimum nZEH design.
