Save Energy

The current world condition where the availability of energy especially non-renewable energy is running low, we are required to be able to use available energy efficiently and as economically as possible. Amid the not yet socialized use of alternative energy, these demands are mandatory. One key to saving energy is the use of electrical energy to meet the needs of lighting and air conditioning. Some ways that can be done to save energy are through the management of utility systems, user behavior and consistency of knowledge related to energy-efficient buildings. Some of the principles used in energy-efficient development are minimizing fuel, adjusting to the surrounding climate conditions, using appropriate materials, while still providing comfort to the user. The method used in this research is a qualitative descriptive method focusing on efforts to minimize energy use in buildings.

Energy Efficient Buildings

Rising demand and limited production of electricity are instrumental in spreading the awareness of cautious energy use, leading to the global demand for energy-efficient buildings. This compels the construction industry to smartly design and effectively construct these buildings to ensure energy performance as per design expectations. However, the research tells a different tale: energy-efficient buildings have performance issues. Among several reasons behind the energy performance gap, occupant behavior is critical. The occupant behavior is dynamic and changes over time under formal and informal influences, but the traditional energy simulation programs assume it as static throughout the occupancy. Effective behavioral interventions can lead to optimized energy use. To find out the energy-saving potential based on simulated modified behavior, this study gathers primary building and occupant data from three energy-efficient office buildings in major cities of Pakistan and categorizes the occupants into high, medium, and low energy consumers. Additionally, agent-based modeling simulates the change in occupant behavior under the direct and indirect interventions over a three-year period. Finally, energy savings are quantified to highlight a 25.4% potential over the simulation period. This is a unique attempt at quantifying the potential impact on energy usage due to behavior modification which will help facility managers to plan and execute necessary interventions and software experts to develop effective tools to model the dynamic usage behavior. This will also help policymakers in devising subtle but effective behavior training strategies to reduce energy usage. Such behavioral retrofitting comes at a much lower cost than the physical or technological retrofit options to achieve the same purpose and this study establishes the foundation for it.

Energy Efficient Buildings

Cooling, Heating and Power (CHP) systems are a form of distributed generation that uses internal combustion prime-power engines to generate electricity while recovering heat for other uses. CHP is a promising technology for increasing energy efficiency through the use of distributed electric and thermal energy recovery-delivery systems at or near end-user sites. Although this technology seems to be economically feasible, the evaluation and comparison of CHP systems cannot be restricted to economical considerations only. Standard economic analysis, such as life cycle economic analysis, does not take in consideration all the benefits that can be obtained from this technology. For this reason, several aspects to perform a non-conventional evaluation of CHP systems have to be considered. Among the aspects to be included in a non-conventional evaluation are: power reliability, power quality, environmental quality, energy-efficient buildings, fuel source flexibility, brand and marketing benefits, protection from electric rate hikes, and benefits from promoting energy management practices. Some benefits of these non-economical evaluations can be transferred into an economic evaluation but others give intangible potential to the technology. This paper focus on a non-conventional evaluation based on energy-efficient buildings, which is associated to energy conservation and improvement of the building energy performance rating for government energy programs like Energy Star and Leadership in Energy and Environmental Design (LEED). Results show that the use of CHP systems could improve the Energy Star Rating in more than 50 points. The Energy Star Rating is significant on the LEED Rating as a building can score up to 10 points of the 23 available in the Energy & Atmosphere category on energy efficiency alone. As much as 8 points can be obtained in this category due to the Energy Star rating increment from the use of CHP systems. Clearly the use of CHP systems will help building owners to reach the benefits from these energy programs while improving the overall energy use and energy cost.

AbstractPromoting efficient energy use in schools that consequently reduces greenhouse gas emissions is the purpose of a residential Energy Efficiency in Schools (EEIS) program reported on in this paper. Research on this program aligns with one of the “key overarching sustainability issues”, set out in the Learning for Sustainability: NSW Environmental Education Plan 2002-2005: “Sustaining energy use, cutting greenhouse gases”. The EEIS program was sponsored by Queensland EPA, Ergon Energy and Education Queensland. Participants learnt about innovation, leadership, coal mining, greenhouse issues, the “greenhouse challenge”, conducting energy audits, alternative energy and promoting energy efficient practices in school and the community.Three EEIS models in Queensland that supported change in energy usage behaviours of participants (school students, parents and staff) is examined. In each of the models, interviews were conducted and questionnaires were completed with participants. In Model 1 it was found that, overall; the EEIS program did develop positive energy efficient behaviours in those who participated. In relation to whole school effects, mixed results were obtained. In Model 1 a rural school initially reduced energy consumption by fifty percent and in Model 2 significant changes in energy efficient behaviours in the school communities occurred. In Model 3 one school followed through an action plan and similar positive effects were observed. The development of an action plan that is implemented in the school, the selection of suitable participants, and post-program visits to schools by relevant staff were among the factors that contributed to the overall success. Each model was found to have achieved their aims to varying degrees but had outcomes that are likely to have both lifetime and possibly intergenerational effects.

Energy Efficient Buildings

Buildings are significant consumers of energy and producer of greenhouse gases worldwide, and serious efforts have been put into designing energy-efficient buildings. Significant technological advances have been achieved in developed countries; however, advances have rarely been adopted in developing countries like Afghanistan. Such trends emerge from the lack of research in designing energy-efficient buildings to local conditions, practices and materials. This research focused on building energy modelling and simulation to evaluate the energy performance impact of different shading and orientation. The research design follows a case study over an actual seven-storey multi-apartment residential building in the city of Mazar-I-Sharif, Afghanistan, using primary field data and dynamic simulation. Findings demonstrated that neighbouring structures have a positive correlation with a cooling demand. Meanwhile, south is the optimal orientation to face the building's glazed façade, saving up to 7.4% of cooling and 9.7% of heating energy. Moreover, movable shading devices installed on the building's openings in the summer season reduce the building energy load up to 19%, with a total energy cost reduction of AFN. 188,448 ($2447.37 US) annually. The study underlines the vast research scope in customizing building designs to Afghanistan's climatic conditions and other developing countries, thus contributing to buildings’ sustainability.

Energy Efficient Building

Reduction of energy use in buildings is an important measure to achieve climate change mitigation. It is essential to minimize heat losses when designing and building energy efficient buildings. For an energy-efficient building in a cold climate, a large part of the space heating demand is caused by transmission losses through the building envelope. To achieve this, it is necessary to have processed a detailed design of buildings. Thermal bridges have to be eliminated in the design of buildings. Thermal bridges occur as point ones or linear. One of the specific details that create thermal leakage is located in balcony slabs. The balcony is one of the main reasons of the increased heat loss of buildings. The presence of thermal bridge in constructions of balcony envelopes influences the energy consumption, durability of the building envelopes, and also the thermal comfort of occupants. This paper is focused on advanced analysis of thermal performance of thermal break element applied in balcony slab with parametric correlation to the thermal properties of wall building envelope.

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 Cost

A well-designed energy efficient building maintains the best environment for human habitation while minimising the cost of energy. The energy efficient buildings are to improve the comfort levels of the occupants and reduce energy use (electricity, natural gas, etc) for heating, cooling and lighting (Development and Land Use Policy Manual for Australia, 2000 and United Nations, 1991). This paper is an inquiry to investigate the users' perceptions towards lights and space of energy-efficient buildings. The research is based on qualitative and quantitative data collection. The findings revealed that users have mixed feeling towards light and space especially with the use of new working practices i.e. hot desking, hotelling etc. Keywords light, space, user perception, energy efßcient building. eISSN 2514-751X © 2018.
