The demand for some products, such as energy, does not instantaneously respond to price changes. In fact, sluggishness of the demand is an important characteristic of energy and oil markets. This study examines the effect of demand sluggishness on the price and output of a fossil fuel industry in which a cartel and a fringe firm supply in the market. The cartel has larger reserves and less cost...

real-time pricing schemes make the customers to feel the energy price volatility and improve their load profiles. however, these schemes have no significant effect on demand-side uncertainty reduction. in this paper, considering smart grid infrastructures and smart building energy management system (ems), a new real-time pricing scheme is presented to reduce the uncertainty of demand-side. in t...

School buildings as a major part of public buildings are considered as one of the basic consumers of energy in Iran. Based on building typology and occupancy patterns, school buildings have a great potentiality for energy optimization while providing thermal comfort. This study investigates the architectural design parameters such as orientation, optimum window to wall ratio, space organization...

In this study, by using manufacturing firms' cost functions and their demand for inputs, we attempt to find the relationship between production inputs and energy carriers during (2005-ا2013). A dynamic model is implemented to derive the short and long-run elasticities of demand and substitution. The results show that during the period 2005-ا2013, energy and capital were complement for labor, a...

gasoline is the most important energy product in the passenger transportation sector in iran. gasoline demand survey has a high priority in iran because of its ever-increasing consumption. the most important challenges for this purpose are uncertainties resulting from structural failure of economy, changing of policies and lack of accurate data. this research aims to specify the variables expla...

Energy carrier’s subsidization has placed a significant pressure on government budget in Iran thus, energy price increase is performed in order to ameliorate this case. One of the main challenges that policymakers need to consider is the impact of energy prices increase on the labor market especially, when the national unemployment rate is high. This paper utilizes a computable general equilibr...

Double Skin Façades (DSF) is one potential response to two major problems, i.e., low Indoor Environmental Quality (IEQ) and high energy consumption. The second skin provides thermal comfort, optimal sound performance, and better day lighting and ventilation. Many typologies of DSFs are widely used mostly in countries of cold climates. In Iran, however, they are less known, and therefore,...
