This paper involves assessing radon concentrations at the heating, ventilating and air conditioning (HV AC) environment of Hong Kong University of Science of Technology (HKUST). Ninety rooms with various configurations were selected at random and evaluated in detail. A time-integrated active sampling instrument as well as a passive activated charcoal canister radon detection system were used for the study. With the central HV AC system in the normal operating mode, data on location characteristics, as well as average and peak radon concentrations were collected and analysed.
This paper describes the management of radon concentrations at the Hong Kong University of Science and Technology (HKUST). Applying our derived specific modification factor in the radon concentration predictive mathematical models, we were able to accurately estimate radon concentrations under different conditions of Heating, Ventilating and Air conditioning (HV AC) operations. Various combinations of HV AC operating schemes were tested mathematically. Many possible combinations demonstrate optimal effects.
This paper reports on the experimental results using a standard room chamber to evaluate the impact of various parameters on indoor radon concentrations. The paper assesses the suitability of using pro-existing mathematical models for the prediction of indoor Volatile Organic Compounds (VOC) to estimate radon concentrations in the heating, ventilating and air conditioning (HV AC) environment. A test chamber study was conducted to thoroughly evaluate and validate parameters considered in these models.
Advanced Fabric Energy Storage allows buildings to maintain a comfortable internal environment whilst incurring a significantly reduced energy consumption and financial cost This paper provides a concise reference of the key design features of advanced Fabric Energy Storage, sharing experience gained from several years of involvement with the first UK projects.
In the previous issue of this Newsletter, the THERMIE Programme was presented through an interview with Mr Sampaio Nunes, Director of Energy Technology at the EC's DG XVII. In order to illustrate the Programme, this issue's subject is focused on the presentation of actual projects: six new so-called Targeted Projects have indeed been approved for THERMIE support in the Building sector after the 1995 and 1996 calls, and are now getting up to speed.
