In order to maintain good performance and a timeefficient calculation period to simulate an entire urban environment, the simulation efforts for single buildings must be as simple as possible. By generalizing all heating load curves using particular density functions, the result is a heating density function for non-residential buildings considering particular constructions and individual occup...

In order to meet ambitious emission reduction goals in California, greenhouse gas emissions from direct combustion of fossil fuels for residential space and water heating will need to be largely eliminated. If those emission reductions come from fuel switching (natural gas to electricity) then the electricity grid needs to be prepared for the additional load. This paper presents a new method fo...

BACKGROUND The most common method of customizing shoe insoles to the shape and surface of the foot is to heat and then mold the materials. The effect of heating on the mechanical properties of these materials is unknown. METHODS The properties of individual and common combinations of insole materials were tested before and after heating. Individual materials tested were soft Plastazote (SP), ...

since the energy consumption has become one of the crisis of modern buildings, modeling the iranian past architecture patterns could be helpful. the shopping streets as one of the main sectors consuming energy locate near the open spaces it seems, therefore, they need more thermal comfort. however, using passive techniques, the iranian traditional bazaars architecture solved the problems regard...

─ A new functionality for the hybrid electromagnetic – thermodynamic simulations of microwave heating scenarios in the time domain is presented. The new functionality consists in the modelling of the heated load movement throughout the simulated process. Various types of the movement trajectories have been allowed for, including load rotation and load translation along user-defined piecewise-li...

Abstract: There exists huge differences in climatic conditions and occupant energy-consuming behavior between Berlin and the “hot summer and cold winter zone of China” (HSCW), which implies that the building energy consumption compositions of two regions are completely different. In this paper, dynamic energy consumption simulation for passive houses with Design Builder software was performed. ...

The 4th generation of district heating systems face a potential problem where lowered water temperatures lead to higher flow rates, which requires hydraulic capacity in terms pipe and pump sizes. This increases the effect already existing issue bottlenecks, causing peripheral units (customers) experience reduced rates. A coordinating control strategy is presented this work aimed at reducing suc...

This article describes a simple model obtained from a commercial Stirling engine and used for heating a caravan. The Stirling engine has been tested in the lab under different electrical load conditions, and the operating points obtained are presented. As an application of the model, a series of transient simulations was performed using TRNSYS. During these simulations, the caravan is traveling...

The recent ASHRAE project, “Updating the ASHRAE/ ACCA Residential Heating and Cooling Load Calculation Procedures and Data” (RP-1199), developed two new residential loads calculation procedures: residential heat balance (RHB), a detailed heat balance method that requires computer implementation, and residential load factor (RLF), a simplified procedure that is hand tractable and suitable for sp...
