Windows energy saving design of residential buildings has increasingly got the attention of people. Through a large number of surveys and analysis of residential buildings in Chongqing and consumers personal experience, the author finds problems and deficiency, and then proposes principles of residential buildings sun shading reconstruction in Chongqing city. Taking the high-rise residential building of one university in Chongqing as reconstruction sample, selecting a specific time period, the author recalculates sun shading coefficient with and without sun shading by using Ecotect software to do simulation analysis. Finally, the reasonable reconstruction design pattern is put forward through cases. Keywords: Buildings Sun Shading, Sun Shading Reconstruction, Energy Saving

High-rise apartments are a prominent type of residential buildings in Canadian cities. However, poor aging performance of existing apartments has led to high discomfort and energy consumption that must be addressed. Thermal energy storage is a potential energy retrofit measure that affects energy consumption by regulating radiant temperatures. The aim of this study is to evaluate the effectiveness of latent thermal energy storage using phase change materials (PCMs) integrated into walls and ceilings of apartment units. A composite PCM system comprised of two different PCM products with melting points of 21.7 oC and 25 oC is proposed and evaluated to provide a year-around thermal energy storage. A simulation analysis using Energy Plus is performed to investigate the impacts of the composite PCM system on indoor temperatures and energy use. An experimental study is conducted using two small scale test cells to monitor the performance of the PCM system in detail.

Solar Water Heating System

With the acceleration of urbanization, high-rise residential buildings have dominated the present residential buildings in which it has become an irreversible trend to apply the solar water heating systems. Taking the common layout models of the high-rise residential buildings in Jinan City as examples, this paper will create models with the help of sunlight analysis software TSUN8.0 to make a simulation analysis of the valid sunlight hours of the southern facade in these buildings, in the premise that they are in line with the planning requirements, thus we may work out reasonable layout programs for the solar water heating systems application into the facade of high-rise residential buildings under different layouts, which can provide the architects with basis in the design of integrating the buildings with the system.

The Impact

This article investigates the possibility to enhance the use of latent heat thermal energy storage (LHTES) as an energy retrofit measure by night ventilation strategies. For this scope, phase change materials (PCMs) are integrated into wall and ceiling surfaces of high-rise residential buildings with highly glazed facades that experience high indoor diurnal temperatures. In particular, this article investigates the effect of night ventilation on the performance of the PCMs, namely, the daily discharge of the thermal energy stored by PCMs. Following previous experimental tests that have shown the efficacy of LHTES in temperate climates, a system comprising two PCM layers with melting temperatures selected for a year-around LHTES was considered. To quantify the effectiveness of different night ventilation strategies to enhance the potential of this composite PCM system, simulations in EnergyPlusTM were performed. The ventilation flow rate, set point temperature, and operation period were the main tested parameters. The performance of the PCMs in relation to the variables was evaluated based on indoor operative temperature and cooling energy use variations in Toronto and New York in the summer. The solidification of the PCMs was analyzed based on the amount of night ventilation needed in each climate condition. The results quantify the positive impact of combining PCMs with night ventilation on cooling energy reductions and operative temperature regulation of the following days. In particular, the results indicate higher benefits obtainable with PCMs coupled with night ventilation in the context of Toronto, since this city experiences higher daily temperature fluctuations. The impact of night ventilation design variables on the solidification rate of the PCMs varied based on each parameter leading to different compromises based on the PCM and climate characteristics.

Probabilistic Risk

Given that existing fire risk models often ignore human and organizational errors (HOEs) ultimately leading to underestimation of risks by as much as 80%, this study employs a technical-human-organizational risk (T-H-O-Risk) methodology to address knowledge gaps in current state-of-the-art probabilistic risk analysis (PRA) for high-rise residential buildings with the following goals: (1) Develop an improved PRA methodology to address concerns that deterministic, fire engineering approaches significantly underestimate safety levels that lead to inaccurate fire safety levels. (2) Enhance existing fire safety verification methods by incorporating probabilistic risk approach and HOEs for (i) a more inclusive view of risk, and (ii) to overcome the deterministic nature of current verification methods. (3) Perform comprehensive sensitivity and uncertainty analyses to address uncertainties in numerical estimates used in fault tree/event trees, Bayesian network and system dynamics and their propagation in a probabilistic model. (4) Quantification of human and organizational risks for high-rise residential buildings which contributes towards a policy agenda in the direction of a sustainable, risk-based regulatory regime. This research contributes to the development of the next-generation building codes and risk assessment methodologies.
