宏观视角

■我国住宅“四耗”严重建设部副部长刘志峰说,目前,我国城市住宅“耗地”已占整个城市用地量的30%,住宅“耗能”已占全国总能耗的37%,“耗材”、“耗水”的状况也不容乐观,住宅建筑用钢量已占全国用钢总量的20%,住宅水泥消耗量占全国总消耗量的17.6%。如果综合考虑住宅使用中的耗能和建材耗能,则住宅总能耗已占全国能耗的37%。尽管我国2/3的城市缺水,但住宅建筑耗水量还是占到了全国耗水总量的32%。■工程建设项目招投标将实行“分餐制”为进一步规范工程建设项目审批(核准)时有关招标内容的核准工作,国家发改委近日印发了《意见》,该《意…

浅谈当下住宅设计的同质化问题与改进创新——以固始珑翠园设计为例

随着我国经济社会的不断发展与生活质量的提高,人们对住宅有着与时俱进的理解和认识,并对其提出了更高的需求。然而大多数住宅的同质化设计无法从根本上满足人们从“住有所居”到“住有优居”的需求变化。本文浅谈如今住宅设计的同质化问题,并从“思路拓展”、“文化赋能”与“技术赋能”三个方面,结合固始珑翠园的设计案例研究应用于现代住宅...     

借鉴美国经验,制定我国未来住宅建筑电气规范

未来住宅规范应该如何制定?2000年小康住宅的目标是要达到国际水平。把国际高水准的规范拿来,让设计人员遵照执行就能建设成高水平的住宅吗?对于我国未来住宅建筑电气规范应如何制定,美国《国家电工法规委员会》一位委员讲了这样一句话:“我不想用任何方式把我们的经验强加于中国,也不希望任何国家完全接受美国的建筑电气规范,但这些规范对于其他国家确是一个很好的范例”。他建议我们认真研究一下“国际建筑电气规范”在美国是如何应用的,把美国建筑电气规范作为参考制定适应自己国家的条     

基于性能的住宅建筑抗震设计分析

基于性能的住宅建筑抗震设计方案既要技术先进,也要结构合理、安全和实用;既要降低工程造价,也要保证抗震设防要求和抵御地震风险的能力。基于性能的住宅建筑抗震设计方案应采用定性与定量相结合、理论与实践相结合的方法;应采用专家、技术人员和工人三结合;应符合现行的设计标准和规范的规定;应依据工程特点和功能要求,合理地选择建设场地和地基;应该选择有利于抗震的住宅建筑平面和立面布置、选择合理的抗震结构体系、处理好非结构构件和严格选用结构材料。     

刘东卫:住宅建造亟需转型升级

近年来,由于国家住宅产业化政策的引导和住宅市场的需求,我国住宅的生产工业化研究与实践已经到了迫在眉睫的地步,虽然住宅产业现代化与住宅的生产工业化得到国内同行的普遍关注,在行业的探索实践上也取得了很多进步,但是对住宅生产工业化课题的认识并非十分清晰,也缺乏对住宅生产工业化方面系统性体系化的研究和实践。提高住宅工业化水平迫在眉睫当前,我国正面临“十二五”建筑产业转型升级的关键时期。转型升级涉及理念的转变、模

瑞典再兴“集成住宅”建造热

上世纪60年代,“集成住宅”曾风靡瑞典全国,成为房地产开发商趋之若骛的一大热点。近几年来,瑞典再次掀起了建造“集成住宅”热潮。 据瑞典著名的斯堪卡土木工程和建筑承包公司(SKANSKA)住宅部经理马茨·约翰松向记者介绍,30多年前出现的第一次“集成住宅”热是在另外一种社会与商业背景之下出现的。当时,经过二次大战后20年的高速发展,瑞典变得非常富裕起来,人们对住宅的要求越来越高,这导致全国住房空前紧张。为此,瑞典议会在60年代中期通过议案,决定在10年内建造100万套住宅,

被动式太阳房阳光间通风口优化设计

针对农村建筑节能改造设计中不同结构的附加式阳光间节能效果差异较大的情况,改良阳光间建筑结构形式并分析其温度场和气流组织分布情况,确定了最优建造方案。以河北省石家庄市某农宅为基础,对其阳光间进行开孔设计。在阳光间内侧墙面上开设不同半径和数量的通风口,设计12种不同的模型。结合Fluent模拟数据,对不同变量进行对比分析,研究不同半径和数量的通风口对室内热环境的影响,确定运行效果最优模型,对运行效果最优和效果最差的两种模型进行对比分析,进行通风口优化设计。结果显示,通风口半径为0.15 m,设置3个进风口2个出风口时,室内温度最高。研究成果可以为附加式阳光间的设计提供参考,可用于改进农宅建筑形式,提升农宅附加式阳光间的节能效益。     

Rational Expectations, Market Fundamentals and Housing Price Volatility

This paper derives a forward-looking rational expectations house price model and empirically tests its ability to explain short-run fluctuations in real house prices. A novel approach to proxying the imputed rents of owner-occupied housing, as a function of observable housing market fundamentals, is combined with a housing market arbitrage relation to derive a present value model for real house prices. Tests of the rational expectations, nonlinear cross-equation restrictions reject the joint null hypothesis of rational expectations and the asset-based housing price model for quarterly, single-detached house prices in the city of Vancouver, British Columbia from 1979–1991. The model fails to fully capture observed house price dynamics in two real estate booms but tracks real house prices well in less volatile times, suggesting that prices may temporarily deviate from fundamental values in real estate price cycles.     

House Search Duration in Hot and Cold Residential Markets

This study analyzes the determinants of house search duration of consumption‐driven buyers and individual investors in different housing market environments. We use data from surveys of recent house‐buyers in “hot” and “cold” housing markets in the 2000s housing bubble in California characterized by rising and declining residential house prices, respectively. The average house price and the surveyed geographical area are the same for both periods. Expected house ownership horizon is shown to be an important determinant of the realized search duration in addition to commonly considered housing and buyer characteristics. We find a statistically significant positive effect of it on the time until purchase in both housing price environments for consumption‐driven buyers. We also find that consumption‐driven house purchases were highly pronounced in coastal areas in the hot market and inland areas in the cold market. In contrast, long‐horizon investment activity leads that of consumption activity in those areas. Short‐horizon investors, on the other hand, concentrated their house search activity in inland areas in both housing market environments.

The Influence of Reference Group House Size on House Price

This article examines the effect of a change in housing consumption of various reference groups on predicted own house price. I employ a spatial autoregressive model and find that an increase in average house size of the eight nearest neighbors and the largest houses in the district has a negative effect on predicted house price, whereas the effect of an increase in average house size of the further neighbors (9th through 16th neighbors) and the smallest houses in the district on predicted house price is positive. This suggests that the “envy effect” dominates with respect to the nearest and largest neighbors, whereas the “basking in the reflected glory” effect dominates with respect to the further smallest neighbors.     

Household portfolio choice before and after a house purchase

Using a unique administrative panel data from Denmark, this article documents the dynamic evolution of households' financial wealth, the equity market participation rate (extensive margin), and the conditional risky asset share of financial wealth (intensive margin) over a 7-year period around a house purchase. We find that households' equity market participation rate falls during the year of house purchase. Conditional on participation, the risky asset share of financial wealth follows a V-shape around the house purchase. It decreases and reaches the lowest point 1 year before a house purchase, but jumps up immediately after. This finding suggests that of the three channels identified in the literature that are related to the risky asset demand after a house purchase, the debt retirement channel and the diversification effect dominate the liquidity concern.     

On the Nature of Self‐Assessed House Prices

In models of optimal household behavior, the value of housing affects consumption, savings and other variables. But homeowners do not know the value of their house for certain until they sell, so while they live in their home they must rely on local house price data to estimate its value. This article uses data from the recent housing boom and bust to demonstrate that changes in households' self‐assessed home values are strongly consistent with the predictions of a model in which households optimally filter available house price data. Specifically, we show that self‐assessed house prices did not increase as rapidly as house price indexes during the boom and did not decline as severely during the bust. A Kalman filter model nearly perfectly replicates these data. These findings have direct implications for economists studying asking prices during booms and busts, optimal default decisions and other key housing‐related phenomena.     

Canadian Inter-City House Price Differentials

The purpose of this paper is to identify the sources of intercity house price differentials in Canada. The results indicate that demand factors are important explanatory variables; a 1% increase in the income of households raises house prices by 1.11%; higher rates of anticipated inflation result in higher house prices as households increase their demand for real assets such as housing during inflationary periods; and finally, the fraction of households that are non-family households is positively associated with house prices. These results are in agreement with those of other countries.
