The case study of a nursery school of Bologna isa pilot example of how hybrid ventilationsystems can be embedded in architecturallysignificant buildings.
The purpose of this paper is to proposestrategies of reducing energy consumption forcooling in residences under hot and humidclimate such as Indonesia.
There is an obvious and indisputable need for anincrease in the efficiency of energy utilization inbuildings.
Maintaining a good indoor air quality (forpeople and building conservation) is obviously thefirst aim of any ventilation system; neverthelessthe main side effect - which is also the mostvisible one - is to spend energy, for heating firstand for tr
Study on Airflow around Building Roof for Design of Natural Ventilationby Chimney-Part2 Wind Velocity Distribution above Building Roof- | 2008 | English
The purpose of this study is to clarify thecharacteristics of airflow around building roofand to provide the guidelines for design ofnatural ventilation by chimney.
On the Relation Between the Energy and Social Characteristicsof the Residential Sector. | 2008 | English
Social, financial, energy and technical data from about 1 1 10 households have been collected during 2004 in the major Athens area. The sample has been divided in seven inconie groups and a detailed analysis has been performed.
Solar Thermal and Electric Desiccant Cooling System,Part 2: Experimental Investigation and Evaluation | 2008 | English
The combined solar thermal and electricdesiccant cooling system is designed, fabricated,assembled and installed in the Laboratory ofBuilding Environmental Engineering of TohokuUniversity.
Potential Influence of Moisture Sorption and Desorption of Walls on SpaceConditioning Load of Residential Buildings | 2008 | English
The hygrothermal performance of houses isrecently being required to indicatequantitatively due to the encouragement ofenergy conservation. Several calculationmethods are practically proposed to evaluateenergy saving measures of houses.
The evaluation of the effectiveness ofcogenerations in energy saving is dependent onthe profile of electricity demand and heatdemand as many experts know.
Performance of Whole-building Pressurization as Countermeasureagainst Stack Effect in High-rise Office Building | 2008 | English
This paper deals with pressurization usingHVAC systems on each floor as acountermeasure against stack effect generated inthe winter in high-rise office buildings that donot use revolving doors at the entrance.
Hybrid ventilation free-cooling simulation in Energy Plus. Application on ashopping center retrofitting, in Portugal. | 2008 | English
Buildings take a great share on the total energyconsumption and C02 emissions in Portugal.Poorly thought buildings pollute the urbanspace, and contribute to the increasing buildingssector energy demand.
Simulation on evaluation of Indoor air pollutant difhsed in the crawlspace of detached house | 2008 | English
As the technology in building materialsadvances, the room air pollution caused bychemical compounds, and also by preservativesand insecticides for termite control, has becomea serious problem.
Distribution of contaminants in the occupied zone of a room served by a novel enhanced displacement ventilation system | 2008 | English
The aim of this study is to examine contaminantdistribution in the occupied zone of a room servedby a novel enhanced displacement ventilationsystem which brings cooler air near the floorupward around human body via 4 fans mounted ateach corner of
The concentration in the convection flows ofresuspended particles from the floor area wasexperimentally investigated under laboratoryconditions with different ventilation strategies.It was concluded that the number of smallparticles transported in
In building design the requirements for energyconsumption for ventilation, heating and coolingand the requirements for increasingly betterindoor climate are two opposing factors.This paper presents the schematic layout andsimulation results of an
The use of floor heating has been know sincemore than 3000 years from the Chinese Kang,the Korean Ondol, the Romans hypocaust to daysmodern water based systems embedded in thefloor construction.
Effect of technical solutions on non-heating and non-cooling temperatures and free cooling potential in office buildings | 2008 | English
In this paper we analyze by means ofbuilding simulation the effect of differentparameter combinations on the non-heating andnon-cooling temperatures of a typical airconditionedoffice building.
The Mechanical supply only (MSO) ventilationsystem has many advantages, such as good airdistribution, easy pre-heating of cold fresh airsupply and prevention of chemical aerosolsintake through wall cavity.
Adaptive Mesh Refinement Method Suitable for CFD Analysis of WindEnvironment around Buildings | 2008 | English
In order to generate effective grid for CFDanalysis of wind environment around buildings in urban area, we newly develop non-uniformtype adaptive mesh refinement method(NUAMR).
