摘要
基于对失能老人居家养老支持性需求中物理环境需求的考虑,探究我国不同年代既有住宅失能老人居室空间的光热环境现状以及舒适性情况。文章以哈尔滨为例,选取2000年前后建造的失能老人住宅典型户型3户,对其居室空间的天然光照度、温度、湿度、风速以及空气品质进行连续实测,获得居室物理环境现状,分析其天然光环境、热湿环境、光热环境以及空气质量情况,并进行舒适性评价,发现其亟待改造的物理环境因素。研究表明:一、2000年前住宅居室采光效果差,天然光环境急需改善,且当室内平均照度低于600 lx时,失能老人开始普遍认为光环境舒适性降低;二、调研期间,2000年后住宅居室室内外平均温度差低于2000年前住宅居室,室内温度与室外温度相关性较2000年前住宅居室高,室内温度较不稳定,部分时间室内热湿环境情况落在 ASHRAE舒适区以及夏季实际热舒适区间外,在获得更加稳定舒适的热湿环境方面仍需改进;三、居室空间的光热环境有一定关联性且受外窗影响,如通过改造外窗提升室内环境质量需考虑光热环境平衡问题,改造受限时也可通过调整功能布局以适应现有光热环境。本研究将为今后失能老人住宅适老性环境改造提供更有针对性的研究基础。
This study focuses on the main activity space of the disabled elderly living with diseases for a long time:living space.Based on the consideration of the physical environment demand in the support demand of the disabled elderly for home care,this study explores the current situation of the light environment,heat environment and comfort of the living space of the disabled elderly in the existing residence in China in different years through field survey,in order to provide more targeted ideas in helping the disabled elderly to obtain good natural light environment and stable and comfortable heat and humidity environment support in the future transformation practice of existing residential environment for the disabled elderly,so that the disabled elderly can obtain a higher quality of life in the period of home-based elderly care with diseases,and then delay the development process of disability.According to the relevant survey and analysis data,84%of the elderly in China live in the residence built before 2000.Is the living environment provided by the old houses suitable for the disabled elderly to live for a long time Whether the living environment provided by the new houses is higher than that provided by the old houses,in the future,what aspects should be focused on in the environment transformation of the existing residence of the disabled elderly for the purpose of improving environmental comfort?Around the above problems,this study takes Harbin as an example,selects three typical house types of disabled elderly built around 2000,of which five disabled elderly people with different degrees of disability lived.Using the survey method of measuring the objective physical environment,natural illumination,temperature,humidity,wind speed and air quality of the living space are continuously measured to obtain the current situation of the physical environment.At the same time,the subjective questionnaire survey is combined to understand the real use feeling of the users.After that,analyses of its natural light enviro
