Structure analysis of building functions transition on the earthquake area five reviewed from costs and time schedule

The purpose of this study is to determine the dimensions and reinforcement of structure, cost, and schedule due to the transition structure of the building function. The structural transition of building functions is carried out in the earthquake area five with the classification of soft and hard soils. The building used as a research model is a 3-story residence on Nuansa Utama Selatan Street number 3, Jimbaran, Bali. The planning of this building will be converted into office buildings and shophouse on the 2nd and 3rd floors functioning as a warehouse in the earthquake area five in Bali with the classification of soft and hard soil that will be analyzed using SAP 2000 program so that the structural dimensions are used as a reference in the creation of costs, and schedule obtained using Microsoft Project program. The analysis of structure shows that the structure of a residential house on hard soil has the dimensions and reinforcement of the smallest structure. The ratio of structural reinforcement in the transition of structure functions from residential house to office on hard soil by 1.32% with the lowest structure cost ratio by 1.80% and schedule of the structure by 3.80%.

Design A Lighting Point Calculator System For Residential Houses Using Microsoft Visual Basic

Lighting point calculation plays an important feature in developing a new residential house. This enables people inside the house will have enough of light to perform tasks efficiently. Currently, consulting electrical engineers use rules of thumb to forecast the quantity of lighting points, however these rules are inaccurate. It does not take into account the lux required based on Malaysian Standard MS1525. Furthermore, good lighting can save money and provide visual comfort to the occupants. However, numerous parameters such as room index, utilisation factor and illuminance used for each space or room inside the house must be considered when determining the quantity of lighting point for a residential property. Three types of residential houses are considered which are: single storey house, double storey house and condominium house. This paper presents the development of lighting point calculator system for residential houses using Microsoft Visual Basic and comparison of quantity of lighting point using manual calculation using Microsoft Excel and simulation calculation using Microsoft Visual Basic.

PV-EV Integrated Home Energy Management Considering Residential Occupant Behaviors

Rooftop photovoltaics (PV) and electrical vehicles (EV) have become more economically viable to residential customers. Most existing home energy management systems (HEMS) only focus on the residential occupants’ thermal comfort in terms of indoor temperature and humidity while neglecting their other behaviors or concerns. This paper aims to integrate residential PV and EVs into the HEMS in an occupant-centric manner while taking into account the occupants’ thermal comfort, clothing behaviors, and concerns on the state-of-charge (SOC) of EVs. A stochastic adaptive dynamic programming (ADP) model was proposed to optimally determine the setpoints of heating, ventilation, air conditioning (HVAC), occupant’s clothing decisions, and the EV’s charge/discharge schedule while considering uncertainties in the outside temperature, PV generation, and EV’s arrival SOC. The nonlinear and nonconvex thermal comfort model, EV SOC concern model, and clothing behavior model were holistically embedded in the ADP-HEMS model. A model predictive control framework was further proposed to simulate a residential house under the time of use tariff, such that it continually updates with optimal appliance schedules decisions passed to the house model. Cosimulations were carried out to compare the proposed HEMS with a baseline model that represents the current operational practice. The result shows that the proposed HEMS can reduce the energy cost by 68.5% while retaining the most comfortable thermal level and negligible EV SOC concerns considering the occupant’s behaviors.

Adequate BIM level of detail for LCA energy simulation

<p>This research tested the new LCAQuick Residential, a computer-based analysis tool developed by BRANZ (available from www.branz.co.nz). This tool is designed to allow the ready preparation of a LCA at an early point in the design process for a residential house. The research problem was created by the infancy of the program and its unknown ability to produce results to support decision making to include Life Cycle Analysis (LCA) for designers and developers seeking a more sustainable design outcome. The method of testing was to take a real house design and model it using Autodesk Revit™ to create a virtual model. The virtual model was then used to input material quantities into LCAQuick Residential, which in turn generated a full set of Life-Cycle Energy (LCE) data. To test this approach, the data from a Quantity Surveyor (Schedule of Quantities) was also used as input to LCAQuick Residential, and the results compared. For this research on the energy component of LCA was examined – the LCE. It was found that the material quantities generated by each of the approaches differed, and it was necessary to critically compare them to ensure material volumes, density and quantity were appropriately matched and entered into the tool. Considerable care was also required to ensure materials were correctly identified and allocated to the appropriate LCAQuick library material.</p>

Evaluation of Non-Autoclaved Aerated Concrete for Energy Behaviors of a Residential House in Nur-Sultan, Kazakhstan

Autoclaved aerated concrete (AAC) is commonly used as a modern, energy-efficient construction material in Nur-Sultan, Kazakhstan—the second-coldest national capital in the world after Ulaanbaatar, Mongolia. The autoclave curing method used to manufacture the AAC has potential risks and is environmentally costly because of its high-pressure and -temperature operation. Therefore, for phase I and II studies, non-autoclaved aerated concrete (NAAC) was cast, and its properties were evaluated in terms of compressive strength, density, porosity, and thermal conductivity. Moreover, the thermal conductivity prediction model of NAAC was successfully developed. In this Phase III study, the energy behavior of the NAAC was evaluated by energy simulation for a typical two-story residential house model in Kazakhstan. Different wall materials, such as fired brick and normal concrete, were adapted to compare the energy performance of NAAC. Finally, the annual heat loss and amount of heat transferred through the wall of the house were calculated to cross-check the energy-saving effect of NAAC. It was found that the NAAC conserved energy, because the heating and cooling loads, annual heat loss, and amount of heat transfer of NACC were lower than those of fired brick and normal concrete.

Space Transformation in Residential House Small Entrepreneurs Banana Sale

Space transformation occurs in line with the needs and availability of resources owned by space users. The arrangement and utilization of space is carried out to optimize the function of the space owned and the limited space owned by the space user requires an adjustment in the use of the space owned to achieve business goals as well as the comfort of the living environment. Pante Bidari is a banana sale producing area in Aceh, which is located in East Aceh Regency, where the majority of the people work as small entrepreneurs and workers in the Banana Sale Industry. The process carried out when producing Pisang Sale uses a special room consisting of a storage room, peeling room, sale room and packaging room. This study aims to determine how the transformation of space in a small banana sale house. The method used in this research is a qualitative method. This study found that the spatial transformation that occurred in the small businessman's house of Pisang Sale in Pante Bidari District, East Aceh Regency is one way to optimize the utilization and utilization of space, so that the Pisang Sale production room consists of storage room, stripping room, sale room and packaging room. using residential space as an aspect of activity in residential homes, so that ongoing activities are not disturbed by other activities, residential space in terms of space dimensions there are changes that include addition, reduction and movement of space aimed at adjusting space requirements. Judging from the spatial relationship, there are several spaces that are far from each other and close to each other, so that access to activities carried out can optimize the function of the space.
