新建建筑申报一二三星级绿色建筑,围护结构热工性能要求提高,主要降低外墙、屋面及外窗的传热系数及外窗的太阳能得热系数,这需要增加围护结构保温材料厚度。本文收集夏热冬冷地区申报绿色建筑项目案例,通过对部分公共建筑项目案例建模分析,计算不同星级建筑围护结构保温材料的厚度,并与国家建筑节能设计标准要求进行对比,分析不同星级绿色建筑保温材料的厚度变化,对该地区的新建建筑确定绿色建筑增量成本提供一定的依据。 相似文献

在节能建筑、绿色建筑、零能耗建筑中,功能型节能材料起着难以替代的作用。“企口”型混凝土腔发泡自保温砌块以多排孔、不通肋式砌块结构来阻止“热桥”的形成,在保障砌块强度、耐久、保温等综合性能的前提下,控制砌块自身容量,再以“聚合物改性发泡混凝土”填充到砌块腔内作为节能核心材料,改性发泡混凝土注入砌块腔内与壳体内壁浑然一体,起到憎水防水功能,获得整体的节能效果,并可实现保温体系与建筑物同寿命。 相似文献

Green roofs are a passive cooling technique that stop incoming solar radiation from reaching the building structure below. Many studies have been conducted over the past 10 years to consider the potential building energy benefits of green roofs and shown that they can offer benefits in winter heating reduction as well as summer cooling.This paper reviews the current literature and highlights the situations in which the greatest building energy savings can be made. Older buildings with poor existing insulation are deemed to benefit most from a green roof as current building regulations require such high levels of insulation that green roofs are seen to hardly affect annual building energy consumption.As over half of the existing UK building stock was built before any roof insulation was required, it is older buildings that will benefit most from green roofs. The case for retrofitting existing buildings is therefore reviewed and it is found there is strong potential for green roof retrofit in the UK. 相似文献

Insulation materials are the key tool in designing and constructing a energy thrifty buildings. This is demonstrated by the increasing thicknesses used in buildings, which also reflects in the growing sales of the branch. The European market of insulation materials is characterised by the domination of two groups of products inorganic fibrous materials and organic foamy materials. They all feature similar performance in terms of insulating capabilities, but otherwise present significant differences. These are discussed in detail in the following paper. Despite the fact that the thermal properties of the materials has not improved significantly of the last decade, a series of other features, like reaction to fire and moisture or mechanical properties have improved, sometimes even at the cost of insulation abilities. Furthermore, environmental and public health aspects play an increasing role, both in the search for ‘optimum’ materials for given applications, and in the aims set by the industry for future developments. These aims, examined within the legislative and market framework, are discussed in this paper, both as criteria for evaluating state of the art materials and as goals for future research developments. 相似文献
