The industrial sector needs solutions and strategies that allow buildings to reduce their energy consumption and develop their daily business activities. This paper discusses the long-term monitoring measures of indoor thermal conditions in a warehouse with zero energy consumption. The objective is to promote the use of passive design strategies within the industrial sector by analyzing an example of the feasibility of achieving controlled environmental conditions with zero energy consumption. In total, more than a million data points were processed and analyzed in different periods of the year. Experimental measurements showed strong gradients in the vertical distribution of temperature, this being a key aspect of the general behavior of the indoor environment of the warehouse. A standard comparison variable was developed to quantify the monthly and daily evolution of vertical stratification of the air to explain in detail the thermal behavior of the warehouse throughout the year. The results showed the efficacy of the design of these constructions to mitigate the high temperatures typical in a Mediterranean-Oceanic climate. This example of ingenuity in passive design demonstrates how, by combining the right strategies, the desired conditions can be obtained without any energy consumption.

INTRODUCTION Recent development has seen a drastic increase in energy use trends in Saudi Arabian buildings leading to a demand for an effective course of action for energy conservation and production. A case study-based research initiative exploring near-zero energy potential in Saudi Arabia was undertaken. A 4-bedroom detached single-family faculty residence at King Fahd University of Petroleum and Minerals (KFUPM) representing common regional housing design trends was utilized. A base case simulation model of the house was developed and validated using short-term and real-time energy consumption data. Three sets of strategies: passive design strategies, representative codes and standards, and renewable technology were employed in the new design of the house. Passive strategies comprised a green roof, a ventilated wall system, a sloped roof, and insulation for thermal bridges. These alternatives helped reduce the annual energy consumption of the house by 17.2%. The most recent version of the International Energy Conservation Code (IECC 2012) was also incorporated along with ASHRAE Standard 62.2 for ventilation. The code and standard together reduced the annual energy consumption by 31.1%. Solar PV was then utilized to reduce grid utilization for the remainder of the house energy loads. This strategy provided 24.7% of the total energy consumed annually. A combination of strategies showed a 70.7% energy consumption reduction, thereby decreasing the energy index of the house from 162.9 to 47.7 kWh/m2/yr. The Zero Energy Building (ZEB) concepts and strategies utilized in this study demonstrate a socially responsible approach to achieving near-zero energy performance for an existing house.

This study aims to assess passive design features through the extensive modifications of building envelopes to affect the energy efficiency of residential buildings in hot arid climates. In support of the aim of this research, the annual electric energy bill of a typical residential building in Sharurah was collected and analyzed. Then, the DesignBuilder simulation program was used to investigate how different modifications of building envelopes could affect the energy consumption of the residential buildings under common scenarios. Varied thermal insulation, different types of glass, shading devices, and green roof were investigated with this perspective. The simulation results show that thermal insulation can significantly reduce annual energy consumption by as high as 23.6%, followed by green roofs. In contrast, shading devices and glazing system types were fewer superiors. The results also indicate that the effective combination of certain strategies can reduce total energy consumption by 35.4% relative to the base case (BC) of this research.

Global climate change is serving as warning signs it gradually begins to capture the attention of people at large. Many actions have been and continue to be taken by governments and organizations to preserve the planet, which is impactful and needed. But conservation efforts are not exclusive to governments and large institutions- individuals can contribute in multiple ways that will have ripple effects, one being the choice to build sustainable, net-zero energy homes. Building a house that is a net-zero energy requires many strategies.One of the most compelling factors in reducing the home energy consumption, to then achieve a net-zero energy home especially in hot-dry regions, is the optimization of the building envelope performance. This paper discussed several building envelope design strategies that are suitable for homes in hot-dry regions and tested them.The Methods including analyzing case study from Qater by using computer and were analyzed using Building Information Modeling (BIM) tools for energy simulation programs. All those strategies were applied to a design proposal for a house in Riyadh, Saudi Arabia, which is a hot-dry region. Further, the same simulation analyses were projected onto an identical house to the design proposal, but with a traditional, low-efficient building envelope.The results showed that the house with the high-efficient building envelope had 48% less energy consumption than the one that has the low-efficiency envelope.This research demonstrated the efficacy of the building envelope to reduce the energy consumption of single-family homes in hot-dry regions. The study outlines vital strategies for a high-efficient building envelope design in hot-dry areas that reaching net-zero energy homes and thus help to offset the negative impact of climate changes in arid areas.

Despite their high energy consumption, rural residential houses in the hot summer and cold winter (HSCW) zone still have a generally poor indoor thermal environment. The objective of this study was to understand the current status of the indoor thermal environment for rural residential houses in the HSCW zone and analyze its cause in order to develop some strategies for improvement through passive design of the building envelope. Face-to-face questionnaires and interviews, air-tightness testing, and temperature and humidity monitoring were conducted to understand the building envelope, energy consumption, and indoor thermal environment. Then, some passive design strategies were simulated, including the application of functional interior materials such as hygroscopic and phase change materials. An overall passive design for the building envelope can increase the room temperature by 3.6 °C, reduce the indoor relative humidity by 12% in the winter, and reduce the room temperature by 4.4 °C in the summer. In addition, the annual energy-saving rate can reach ~35%.

Purpose The purpose of this paper is to develop a set of affordable retrofit packages that can be applied to existing residential buildings in hot-humid regions to improve occupants’ thermal comfort and reduce energy consumption. Design/methodology/approach A critical review of relevant literature to identify passive design strategies for improving thermal comfort and reducing energy consumption in hot-humid climates with focus on the building envelope was conducted in addition to a simulation study of an existing building typology in study area. Findings There is enormous potential to reduce energy costs and improve thermal comfort through building retrofit packages which is a recent concept in developing countries, such as Nigeria. Analysing the results of the retrofit interventions using building energy simulation helped in developing affordable retrofit packages which had optimum effect in improving indoor comfort temperature to the neutral temperature specified for hot humid Nigeria and further down to 3°C less than that of the reference building used. The use of passive design strategies to retrofit the building might help homeowners reduce their annual energy consumption by up to 46.3 per cent just by improving the indoor thermal comfort. Originality/value In addition to improving thermal comfort and reducing energy consumption, this research identified affordable retrofit packages and considered its cost implications especially to low-income earners who form a larger population of Lagos, Nigeria, as this was not considered by many previous researchers.

Correct Design

Passive design strategies aim at creating comfortable buildings while reducing their energy consumption. Simple strategies such as the correct orientation of the building, the correct design of the building's openings, or the correct sizing of the building's constituent parts (such as walls, ceilings, etc.) according to their material specificities (regarding the region's climate) would greatly improve the performance of a building. This paper intends to show how the application of simple passive techniques in housing design can reduce the energy loads spent annually and improve the house's interior comfort. It translates the results of interior comfort computer simulations into suggestions for the application of passive strategies in housing design, to improve the living conditions in Southern Angola.

ABSTRACT: This research sought to reduce uncomfortable conditions created by extremes of heat and dryness in order to achieve well balanced indoor and outdoor climate, through the application of passive design strategies in Conference Centre located in hot dry climate of Kano Nigeria. Passive design utilizes natural sources of heating and cooling breezes. It is achieved by appropriately orientating the building on its site and carefully designing the building envelope (roof, walls, windows and floor). External features such as fountain, soft landscaping and proper site planning improves micro climate which in turn helped in achieving good passive design. The methodology employed is case study and relevant information sourced from pertinent literature and the internet was taken into consideration. Research has shown that more than40% of energy consumption in any building is used for cooling and lighting in order to achieve comfort level. In the course of the research, the building was studied to evaluate the use of passive elements that relates to passive lighting and cooling which are the main source of energy consumption such as building envelop, natural lighting, natural ventilation, Site and external spaces, building form, building orientation, wall/window shading and existing of energy source on conference centre building. Research has shown that, the design parameters obtained from field survey are the principal factors responsible for any good passive design of most public building such as conference centre building.
