This paper examines air-conditioning loads by several air-conditioning patterns and heat methods of asuper high-rise residence by using the dynamic simulation software THERB (the simulation softwareof the thermal environment of residential buildings) which can estimate temperature, humidity, sensibletemperature, and heating/cooling load for multiple zones of buildings. As high-rise residences, the ratiothat the structural skeleton dominates a floor area is bigger than that of ordinary residences, and itsskeleton is used concrete generally.

The main objective of the ongoing research project described in this paper was to study the potential forreducing energy used for ventilating buildings by using low-polluting building materials, withoutcompromising the indoor air quality. To quantify this potential, the exposure-response relationships, i.e.the relationships between ventilation rate and perceived indoor air quality, were established for roomsfurnished with different categories of polluting materials and the simulations of energy used forventilation were carried out.

Recent studies show that improving indoor air quality (IAQ) from the mediocre level prevalent in manybuildings worldwide improves the performance of office work by adults and the performance ofschoolwork by children. These results constitute a strong incentive for providing indoor air of a qualitythat is better than the minimum levels required by present standards.

The three-dimensional heat transfer performance of the slotted light steel-framed composite wall atminimum temperature is simulated using the finite element software of ANSYS. Based on the simulatedresults of heat transfer and the theory of moisture permeation, moisture transfer of the composite wall iscalculated. The results show that there is no condensation at the inner wall surface at the minimumtemperature in Harbin when the thickness of the wall is 229mm. The condensation may occur in the rockwool near the outer wall.

The VOC removal filter for ceiling cassette type air conditioners was developed as a countermeasure against “sick school”. This paper illustrates basic performance of the developed filter, the detail of toluene removal examinations in an experiment room a

Building energy simulation has proved useful in the development of building energy codes (especiallyperformance-based) and subsequent code compliance checking. A weather year is required for thehourly computation of heating/cooling loads and corresponding energy consumption. Many locationshave measured daily solar radiation data, but not hourly. Attempts were made to model hourly globalsolar radiation (GSR) data from measured daily values using the Liu and Jordan method for Harbin,Beijing, Shanghai, Kunming and Hong Kong.

The concept of a ventilated double façade is invented with the intention of improving the thermal qualities of a fully glazed façade. Over the years, the properties of the single glazed façade have improved. The aim of this study is to compare different v

Introduced in late 90’s, Impinging Jet Ventilation (IJV) is the system that can utilize stratification, while supplying with medium to high velocity. This characteristic makes IJV easy to be controlled and operated, while room Indoor Air Quality (IAQ) can

The European Commission has mandated CEN to produce a set of standards to support MemberStates for the national implementation of the EPBD. This paper focuses on one of these standards,EN ISO 13790, "Energy performance of buildings - Calculation of energy use for space heating andcooling". It describes the history of this standard which started with a simplified calculation of the energyuse for heating of residential buildings only.

Ventilation strategies play an important role of enhancing thermal comfort, Indoor Air Quality (IAQ) andenergy conservation in any conditioned space. Introduced in late 90s, Impinging Jet Ventilation (IJV) isthe system that can utilize stratification, while supplying with high velocity. With this characteristic andthe simplicity of its terminal configuration, IJV has an advantage over well-known DisplacementVentilation (DV) system. In this study, IJV system was investigated for establishing the protocol used inComputational Fluid Dynamics (CFD) simulation.
