实验演算型住宅区地块容积率指标校核方法探索

虽然目前控制性详细规划中容积率等指标的核算有多种手段,但很少有基于实验的演算型定量研究。针对不同大小的基地,均可通过实验,推算日照标准约束下的容积率等指标,作为规划决策的重要依据。从当前日照标准约束角度,提出运用空间极限容积率校核的实验方法,通过计算机实验进行核算。提出了基于＂九宫格＂的计算方法,经过少量人工干预,由计算机生成指标对应的空间形态,以使控制性详细规划指标的确定更加科学、理性。实验表明,如果日照标准约束条件不变,容积率并不是可以随着住宅高度的增加而无限增加。如果需保证一定的日照资源质量,住宅高度和容积率存在增长极限。     

On the margins of urban Europe: housing policies in a secondary city (Cluj,Romania)

This paper discusses recent housing developments in Cluj, a secondary city in Romania. The city is at a point in its development where it is being affected by forces initiated by Romania's accession to the EU. While new housing provision is largely dominated by the private sector, public housing policies are also taking advantage of the new opportunities provided by membership of the EU.     

The geographic concentration of housing vouchers,Blacks, and poverty over time: a study of Cincinnati,Ohio, USA

Using data from the US Department of Housing and Urban Development (HUD) concerning Housing Choice Voucher (HCV, formerly called Section 8) recipients, the authors provide a spatial analysis in Cincinnati, Ohio, USA. ‘Hot spot’ analysis is utilized to detect areas with significant densities of voucher recipients compared with the surrounding environs. Results show that the implementation of Cincinnati's HCV program between 2000 and 2005 in conjunction with public housing transformation has not led to a greater dispersion of voucher recipients and either poverty or racial deconcentration. Many HCV households remain concentrated in hot spots. The implications for US low-income housing policy are discussed.

Defects in offsite construction: timber module prefabrication

The construction industry is based on craftsmanship. Quality control and assurance procedures applied in manufacturing cannot usually be readily applied in construction, where there are higher degrees of uniqueness in each project. One category of companies, industrialized housebuilders, is attempting to bridge some of the gaps between construction and manufacturing. These companies prefabricate building modules for later assembly at the building site. Since they are wholly responsible for large parts of the building process, these companies have greater opportunities to control and improve quality in a more consistent way than ordinary construction companies. Thus, it could be hypothesized that the frequency and severity of defects should be lower in industrialized housing than in ordinary construction. The aim of the study presented here is to examine this hypothesis by measuring and characterizing defects in industrialized housing. The design and manufacturing processes at two Swedish timber module prefabrication firms has been analysed through interviews, site visits and document reviews. Quality audits from three phases of the building process were compiled, analysed and categorized to provide statistical measures of defects in industrialized housing. The results show that the case study companies are better in terms of product quality than conventional housing.
