The purpose of this study is to clarify thecharacteristics of airflow around building roofand to provide the guidelines for design ofnatural ventilation by chimney.
The evaluation of the effectiveness ofcogenerations in energy saving is dependent onthe profile of electricity demand and heatdemand as many experts know.
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.
Determination of air permeability of buildings according to IS0 9972 orEN 13829 - Proposal for clarifications | 2008 | English
Building airtightness is an important parameter that canbe measured according to the International Standard IS09972 "Therm~~l performance of buildings -Determination of air permeability of buildings - Fanpressurization method".Since 2006, there is
Interzonal air movements are important tocharacterize overall ventilation perfosmance ofcomplicated multi-zone indoor spaces.
Measurements and smoke tests show that thequadrants of a Windcatcher with a positivepressure across them act as supply ducts, whilethose with a negative pressure across them actas exhaust ducts.
An integrated building concept is a prerequisiteto come to an energy efficient building with agood and healthy IAQ indoor comfort.
The Decision-making Process for Material and Ventilation Rate consideringIAQ and Cost in Apartment Buildings | 2008 | English
Indoor air concentration is mainly affected bythe emission rate of contaminants frommaterials and the ventilation rate. Therefore, theappropriate selection of materials andventilation rate is an important factor for indoorair quality.
To obtain thermal comfort in a moderateclimate, dwellings were traditionally providedwith a heating system, but few had coolingsystems.
Misawa Homes have developed a homeaiming a zero annual energy balance, definedas the energy consumption over production byusing solar energy, in 1997.
A Study of the Ventilation Performance for Automobile Indoor AirPollution Reduction | 2008 | English
In this study, we evaluated the ventilationperformance of an automobile interior with theaim of minimizing the influence of harmfulmaterials emitted from new cars.
Experimental Study on the Combined Effect of Outdoor Thermal-Environment and Ventilation Patterns on Indoor Thermal-EnvironmentControl for Summer | 2008 | English
If thermal insulation and solar control ofbuilding envelopes are appropriately made forindoor thermal environment control, then themoderate air current becomes relativelyeffective for thermal comfort especially inresidentional buildings in summer
Recently, dampness in buildings has beenindicated to be associated with occupants' healthdamages such as allergies. In particular mold inindoor air is considered to be a significant riskfactor of health.
Building performance can be expressed bydifferent indicators as primary energy use,environmental load andlor the indoorenvironmental quality and a building performancesimulation can provide the decision maker with aquantitative measure of the exte
