Abstract Around the world, most energy is consumed by buildings; residential buildings consume 40% of energy globally. In the Kingdom of Saudi Arabia (KSA), buildings consume 50% of all energy, and 70% of the buildings in the KSA are not insulated well. Creating an envelope is a key to decreasing energy consumption and providing thermal comfort and healthy internal spaces. Thus, the main aim of this study is to test the effect of selected passive cooling strategies by using a simulation program to evaluate a variety of envelope (floor, external and internal walls and roofs) thermal characteristic proposals to create an eco-interior space, to provide the most comfortable conditions for users and to save energy in buildings in hot climates in Riyadh, Saudi Arabia. One residential building case was selected, and some of the passive cooling strategies were tested. Simulation software—Design Builder—was used to calculate the total energy consumption in 1 year and compare the results before and after applying these strategies to the selected residential building.

The amount of energy consumption in the residential buildings has a very significant share with nearly 30 percent in the total amount of energy consumption. Therefore, residential sector is identified in this chapter as being one of the areas with a large potential for energy savings. Inefficient dwelling construction and design methods are widely used in Turkey and only about five percent of residential buildings are insulated. Concerning the importance and immediate need in Turkey for energy-efficient residential building retrofitting, this chapter identifies economic benefits of such retrofitting by particularly focusing on heat transfers by conductivity, where the rate can be determined by surface size, thermal resistance of the building materials and their thickness.

As the climate changed in recent years, an increase in summer indoor temperatures in severe cold and cold regions of China has started to affect thermal comfort. However, the local design standard for energy efficiency does not recognize this phenomenon. This paper reports the potential overheating phenomenon in residential buildings and examines the rationale for the current thermal designs adopted in severe cold and cold regions of China. In this study, the two most commonly used building materials, reinforced concrete (RC) and cross laminated timber (CLT), are used separately in the design of an 18-story residential building envelope located in six different cities in the severe cold and cold regions. The energy consumption and indoor operative temperatures during the operation of these buildings are simulated using Integrated Environmental Solutions Virtual Environment (IES VE). The results demonstrate that both the RC and the CLT buildings experience varying degrees of overheating in any climate subregion. The CLT buildings have longer overheating hours compared to the RC buildings, especially in the cold regions. The results also indicate that for apartments on higher stories, the cooling energy consumption and indoor temperature also increase gradually. The research results suggest that the local design standard for energy efficiency needs to be adjusted by adding thermal design methods for summer to reduce the periods of overheating.

An on-site test on envelope of a typical steel residential building in cold region is performed. The testing results provide evaluation bases for the energy-saving effects of the steel residential building. In order to evaluate the main factors that influence energy dissipation of the building and estimate the main energy dissipation positions, the heat transfer coefficient K of envelope and its actual energy consumption are calculated based on the testing data. The results indicate that the building envelope has good heat storage property and it could keep indoor thermal stability; the steel frames and windows have heat bridge effects. Through calculations of the energy consumption of envelope, it is showed that the tested building only meet the requirement of energy saving by 50%, instead of 65%; the external walls and windows are main energy dissipation parts. Finally the thermal design recommendations about steel residential buildings are proposed.

AbstractAs it is clear, worldwide buildings are the largest consumer of the final energy consumption. In Algeria, it has been reported that 33% of the overall energy consumption was attributed to buildings. This is due to the design and constructional techniques of the residential buildings, which do not address the local climatic condition. To assess this situation, the study is focused on analyzing the existing residential buildings in Algeria, in terms of energy, thermal, daylight, and indoor air quality performance, using a dynamic simulation software. Typical building design in a hot and dry climate was selected. The results revealed that the existing residential buildings do not comply with the energy-efficient design standards. It was concluded that further strategies should be applied in this sector, in terms of building design, materials, and façade configuration.

Proper Design

The building envelope is the most affecting part in the energy interaction between the buildings and the surrounding. Proper design of the envelope components not only can save the required energy for the building but also can improve the thermal comfort of its occupants. In this research, energy modelling and simulation for a residential building in Amman, Jordan is performed to investigate the effects of glazing design and infiltration rate on energy consumption and thermal comfort. Different design alternatives have been investigated to find the best alternative design to reduce energy use and improve indoor environment. The results showed that replacing single glazing window with double glazing window argon-filled with low emissivity coating can save the consumed energy by 24.7% while degrade the thermal comfort by 1%. Reducing the infiltration rate by 50% can save 19.4% of the energy consumed and improves the thermal comfort by 10%.
