Buildings account for 40% of energy consumption in the US. Despite all improvements in buildings shell, equipment, and design, CO2 emissions from buildings are increasing as a result of increased energy consumption. Since occupants spend more than 90% of their time indoors, they are inseparable and significant elements of building system dynamics. Hence, there is a great potential for energy ef...
Urban areas consume up to 80 percent of the world's total energy production and are growing in size and complexity. At present, urban building energy consumption is largely considered solely in terms of individual building types, neglecting the effects of residents’ location-based activities that influence patterns in energy supply and demand. Here, we examine the spatial fluctuations of these ...
Supply fan takes up to 30% of Heating, Ventilation and Air Conditioning (HVAC) systems’ in-building energy consumption. Since the fan power consumption is a cube function of the mass flow rate of supply air, it is thus possible to reduce the energy consumption significantly by elongating and scheduling the pre-cooling processes. To handle the computational complexity raised for large scale buil...
This paper focused on energy consumption and carbon emission for heating and cooling during a building’s operation stage, and examined the energy effects of using Cross Laminated Timber (CLT) as an alternative building material to reinforced concrete (RC) in China’s 31 key cities located in different climate zones. The authors designed two seven-story residential buildings, which were construct...
Introduction and Background: One of the approaches to reduce fossil fuel consumption and their pollution in cities, is to pay attention to the climatic conditions and ecosystems of the region and to use renewable energy in architecture and the design of buildings; This subject in the case for Tehran metropolis is more important, due to the high concentration of population and the activity and, ...
Nowadays, the high rates of energy consumption of buildings in contemporary societies, as well as in global problematics such as climate change, depletion of natural resources and environmental pollution, is widely recognized. In this context, energy efficiency of buildings has become a crucial aspect of national and international energy policies. Nevertheless, the design of high performance bu...
energy consumption in the residential sector is a complex socio-technical problem that can be explained using acombination of physical, demographic and behavioural characteristics of a house and its occupants. in this paper, byusing the energy consumption data for the residential sector of shiraz in iran, the effect of built area (ba) andoccupant number (occ) on annual energy consumption (ec) w...
Upgrading the thermal performance of building envelope of existing residential buildings is an effective way to reduce heat gain or heat loss. Overhang device is a common solution for building envelope improvement as it can cut down solar heat gain and thereby can reduce the energy used for space cooling in summer time. Despite that, overhang can increase the demand for indoor heating in winter...
