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.

Increase Energy Consumption

Construction fillings of buildings such as windows, doors or gates are very often the cause of the increased energy balance of buildings. Especially for energy efficient buildings are windows and doors the weakest parts of the building. Low quality connection of filling construction to a building structure leads to undesirable air leakage, formation of cracks and joints. Joints and gaps reduce the airtightness of buildings, increase energy consumption and reduce the operating efficiency of mechanical ventilation with heat recovery system. The main objective of contribution is to describe and analyze the impact and solution to fillings of buildings on airtightness of energy-efficient 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.

The Impact

Energy supply, the increasing demands for energy, climate change, and the imperative to reduce greenhouse gas emissions must be considered in designing buildings. In order to design energy-efficient buildings, there should be accurate information about the thermal performance of the building. The thermal simulation readings should be precise. Its precision will also have a definite indication of the operational energy costs enabling the likelihood of conserving more energy used in building operations and reducing the greenhouse effect that is a result of emissions of greenhouse gases. Energy-efficient buildings are vital as they reduce the consumption of energy in and allow sustainable development. Erecting such buildings will require correct and realistic prediction of the buildings performance when subjected to a wide variety of harsh weather conditions in order to have a view of the impact of all the physical elements that influence the thermal performance. The behavior of the occupants also influences the thermal performance of a building. To achieve this, energy assessment instruments are used to accurately forecast the buildings thermal performance. This paper critically reviews energy rating methods for housing and the limitations of assessment systems.

Practical Implications

Purpose This paper aims to apply frame analysis to explore the mental models by which building managers interpret the impact of building occupants on energy use and rationalize their approach to occupant engagement. Design/methodology/approach Findings from four energy-efficient buildings (two schools and two office buildings) in Norway are presented. The methodology includes individual semi-structured interviews with both operational and strategic facilities managers Findings Concepts and theoretical perspectives with the potential to shape the building managers’ perceptions include technical knowledge and expertise, management responsibilities, familiarity with occupant routines and understanding of energy-efficient technologies. No significant impact was attributed to the actions of occupants in the areas of comfort, core function and behavior. Significant impact was attributed to their movement and presence. Perceptions of impact were found to influence, yet not determine, the building managers’ choices of practice. Practical implications Factors with the potential to affect the adoption of occupant engagement initiatives were highlighted. This study pointed to the role that automation and centralization can play in influencing facilities managers to rescind from their management responsibilities. Originality/value To the knowledge of the authors, this is the first study to use framings in thoughts to investigate the process by which facilities managers rationalize occupant engagement, in relation to their perception of occupant impact on energy use.

The Impact

According to the U.S. Department of Energy, a significant portion of energy used in buildings is wasted. If the occupancy quantity in a pre-determined thermal zone is aware, a building automation system (BAS) is able to intelligently adjust the building operation to provide “just-enough” heating, cooling, and ventilation capacities to building users. Therefore, an occupancy counting device that can be widely deployed at low prices with low failure rate, small form-factor, good usability, and conserved user privacy is highly desirable. Existing occupancy detection or recognition sensors (e.g., passive infrared, camera, acoustic, RFID, CO2) cannot meet all these above system requirements. In this work, we present an IoT (Internet of Things) prototype that collects room occupancy information to assist in the operation of energy-efficient buildings. The proposed IoT prototype consists of Lattice iCE40-HX1K stick FPGA boards and Raspberry Pi modules. Two pairs of our prototypes are installed at a door frame. When a person walks through this door frame, blocking of active infrared streams between both pairs of IoT prototypes is detected. The direction of human movement is obtained through comparing occurrence time instances of two obstructive events. Thus, the change in occupancy quantity of a thermal zone is calculated and updated. Besides, an open-source application user interface is developed to allow anonymous users or building automation systems to easily acquire room occupancy information. We carry out a three-month random test of human entry and exit of a thermal zone, and find that the occupancy counting accuracy is 97%. The proposed design is completely made of off-the-shelf electronic components and the estimated cost is less than $160. To investigate the impact on building energy savings, we conduct a building energy simulation using EnergyPlus and find the payback period is approximately 4 months. In summary, the proposed design is miniature, non-intrusive, ease of use, low failure rate, and cost-effective for smart buildings.

This publication focuses on the assessment of the impact of structural solutions of single-family buildings with an increased energy standard on their air-tightness level. The first part presents the threats resulting from the low tightness of the building. To formulate the conclusions, quantitative and qualitative casing tightness tests of existing single-family energy-efficient buildings were carried out. Construction and material solutions used in buildings were also analysed. The obtained results indicate that there is no impact of the building structure on its level of air tightness.
