Abstract
Purpose
The paper's objective is to empirically study the effects of building refurbishment on the prices of the dwelling units in a contiguous housing estate in Hong Kong.
Design/methodology/approach
In a congested living environment like Hong Kong, it is difficult, if not impossible, to have a view unobstructed by buildings. As such, the quality of views is dependent on the aesthetic quality of surrounding buildings. It is likely that poorly maintained buildings will impose negative visual effects on their immediate surroundings. Refurbishing these poor buildings should, therefore, reduce or even counter this negative externality. To study the positive externality brought about by building refurbishment, a hedonic price analysis was conducted on a set of panel data consisting of property transactions in a large housing estate located in Pokfulam. This estate was chosen because its adjoining buildings underwent refurbishment in 1998.
Findings
The results showed that the refurbishment increased significantly the prices of those properties which faced refurbished buildings, keeping other things constant. The increments, on average, amounted 6.6 per cent of the prices of the properties.
Research limitations/implications
Building refurbishment can have various scopes and scales but this study did not consider how the characteristics of the building refurbishment affected the prices of neighbourhood properties.
Practical implications
Given the problems of aging buildings in most urban areas, the results presented significant practical implications for building refurbishment and urban renewal as a whole. Developers or property owners may be lured to invest in the refurbishment of adjacent dilapidated properties with a view to enhancing the values of their own properties.
Originality/value
Although previous studies analytically suggested that building refurbishment created positive externality, this study is the first attempt to explore this connection.

Abstract
Purpose
The purpose of this paper is to present a systematic framework for maintenance and refurbishment in domestic housing sector for utilising BIM processes, which tackles ageing housing stock and allows for sustainability improvements, and carbon footprinting.
Design/methodology/approach
The methods used consisted using modern technology currently used in the built environment sector, and applying them to BIM framework. The BIM implementation covered both technical and social implications, and appraisal of different approaches needed to make the framework effective within the housing sector.
Findings
The study revealed that there are many modern approaches for a BIM framework in relation to maintenance and refurbishment, and a possible strategic BM approach largely used in new built sector can be applied to domestic building to achieve effective modern asset management. This makes the housing stock easier to manage as well as addressing vital issues such as carbon footprint, and excessive energy wasted on inefficient buildings envelopes.
Research limitations/implications
Further testing and adoption of the approach and model proposed, will result in greater acceptance of BIM for housing management and greater realisation of benefits.
Practical implications
A potential model that can be used and applied to domestic housing sector as a result of this research.
Originality/value
Demonstration of a road map for BIM applications within the maintenance and refurbishment for housing stock is currently under researched, and the findings aimed to address such a gap. This can in turn shift the focus of BIM towards asset management and building performance rather than just new build.

Abstract
Purpose
This work is initiated under the premise that reliable evaluation methods are necessary to ensure investments in energy conservation, and the purpose of this paper is to contribute to that literature. It describes some pilot changes and their impact in an actual field study oriented toward upgrading municipal public housing (MPH) units.
Design/methodology/approach
The research for this paper was connected to an MPH refurbishment project situated in northern Sweden. The overall energy efficiency goal within the project was a 40-50 percent reduction in the supplied energy for central electricity, domestic hot water and space heating. In order to evaluate if these goals were feasible, a measurement system was installed in a pilot building and in a neighboring building used as a reference. The evaluation was conducted by comparing the post-retrofit performance of the pilot building with the performance of the reference building when it was kept in its initial state (a comparison possible because both buildings had initial similarities).
Findings
Impacts could be quantified insofar as a reference (control) building in the same environment was sustained for comparison purposes. A 43 percent improvement was observed in energy utilization in the pilot building compared to its reference companion (99.8 vs 174.5 kWh/m2 per year). When the approach described herein was applied to new construction, the present goal of 65 kWh/m2 was approached as measured by Swedish standards.
Practical implications
Results should be of interest to academics in the housing field, professionals involved in refurbishment and residents themselves, renting MPH flats.
Originality/value
This study is unique in the following ways: first, it really was a field experiment with a control, thus it did not have any exogenous interference in interpreting results. To the best of our knowledge, this is the first study of its kind. The second interesting characteristic was that results were subsequently used in the refurbishment of other buildings in the complex and in the construction of others. The major value of the paper may be associated with its timing. It comes at a time when the Kyoto agreement has raised concerns about sustainability, but also at a time when many buildings are facing a need for refurbishment.

Abstract
This article deals with the increasing demand for participation in sustainable refurbishment projects. Based on a recently finished study and some conceptual considerations we present a flexible model for involving occupants and other stakeholders in large-volume residential refurbishment projects. The study draws on fifteen interviews with refurbishment experts and three focus group discussions with occupants of recently finished projects. The article shows that in practice it is important to offer approriate opportunities for participation at each phase of the process. Although refurbishment projects in general run through a series of typical phases there is no such thing as a standardized ‘ideal’ participation process. Rather participation designs for large projects have to be ‘tailor-made’, taking into account occupants' expectations and abilities, legal requirements, the complexity of projected measures, and finally the often well established ‘style of communication’ already used by the housing company.

Abstract
Purpose
Belfast's “peace walls” exist to physically segregate and provide a measure of security to the communities on the religious divide in Northern Ireland. Whilst they do ostensibly achieve this aim, it may well be that these structures have the capacity to prevent the restoration of normal community interactions and market processes and may also be providing their benefits at a high price with regard to issues such as house price reduction. Indeed, the effect of these structures on surrounding residential property values remains somewhat of an unknown quantity. This paper therefore measures the effect of proximity to locations with social and political conflicts. The paper aims to quantify and measure the disamenity implications and costs of artificial barriers (peace walls) within the Belfast housing market.
Design/methodology/approach
This paper attempts to measure the disamenity effect of peace walls on house prices, primarily focusing on the effect of distance, calculated using a hedonic pricing specification and spatially referenced data. The data are derived from 3,836 house sales transactions over a one year period in 2011.
Findings
The emerging findings demonstrate that a greater negative pricing effect is evident with proximity to the peace walls, with the exception of the apartment sector. The findings also highlight the complex market pricing structure of Belfast and offer insight as how to best classify submarkets.
Practical implications
The results of the research are of particular interest to property valuers and social policy makers in regions with contested space.
Originality/value
Tactile barriers scar the urban terrain, formalise ethno-segregation across Belfast and have implications for spatial planning in the urban environment and housing studies and policy. Such an externality may have a pervasive and endogenous effect on house prices and the identification of submarkets yet there is implicit acceptance of peace lines as de facto standard and a dearth of empirical evidence relating to direction and magnitude of the location-specific effects of peace walls on house prices in Belfast. This paper is arguably the first to empirically examine the location-specific effects of peace walls on property value across the Belfast area.

Abstract
Purpose
Framed as a pilot study, the purpose of this paper is to study the perceived appropriateness of an existing collaborative procurement procedure (CPP) framework from the housebuilder’s perspective, seeking to improve its utility and stimulate further exploration.
Design/methodology/approach
Informed by an existing CPP framework and conducted by a UK-based development professional, four in-depth semi-structured interviews were undertaken with senior housebuilding practitioners from London and surrounding counties. A qualitative analysis was then conducted for this sociological study.
Findings
Perceived appropriateness of the framework was high; however, a number of procedural improvements were identified, along with limitations. Future studies are recommended including the influence upon project performance of groundworker integration at the design stage.
Research limitations/implications
Limited to four interviews from one regional area, the study provides an initial insight into the appropriateness of an existing CPP framework. Insights into why CP uptake is marginal within housebuilding were also gained. The research purpose was achieved but by offering a self-reflection upon practice (vis-à-vis wider generalisations), the findings provide a springboard for further studies.
Practical implications
The research identifies with current practice, industry perceptions and paths towards improving the utility of the CPP framework.
Social implications
This study offers insights into the perceptions of private housebuilding practitioners of their own practices and the factors they find challenging within the social constructs of their industry.
Originality/value
This research constitutes one of the first studies in the UK to examine the CPP framework from the perspective of the private housebuilder and is undertaken with the express purpose of furthering that framework’s utility.

Abstract
Purpose
The New Zealand construction sector is similar to many other countries with a few large companies and many small and micro enterprises. It seeks to achieve a 20 per cent increase in productivity by 2020 which requires a step change in how the sector operates and buy-in from key stakeholders. The purpose of this paper is to provide a set of levers to improve productivity in the construction sector and develop an implementation schedule.
Design/methodology/approach
This paper adopts a systems approach taking account of the nature of the building sector and the whole life cycle of a building from design to end-of-life. Information gained from the post-construction phases informs the pre-construction and construction phases.
Findings
Productivity is an integrated model whereby increases in process efficiency are executed with quality materials and workmanship, in a manner that is affordable for both the client and contractor and sustainable over time. A series of interviews and workshops produced 10 nodal points and 19 crucial levers which were prioritised for implementation. Additionally, indicators were developed to monitor progress over time and provide information for further corrective action to the system.
Practical implications
The effect of using a few targeted levers in unison provided significantly more gains than individual applications. Modelling real world responses to process stimuli outlined in this paper is extremely valuable. This provided the opportunity for key construction stakeholders to estimate the effects of decision making during a project.
Originality/value
Previous studies identified factors affecting productivity. Piecemeal approaches to improve productivity have resulted in systemic failure. A whole of life approach provides valuable insights to improve productivity in the construction and pre-construction phases which have a flow-on effect through the life cycle. Importantly, this research proposes drivers, an implementation scheme and indicators that provide leverage on nodal points to improve productivity.

Following these findings a proposed research area with focus on energy in the building environment will be suggested for further investigation.
Design/methodology/approach
Through a multilateral review study, a number of major research efforts in sustainable refurbishment are highlighted. The necessity of directing future research towards energy conservation is illustrated for a specific approach to developing the built environment.
Findings
The findings of this article identify high performance thermal insulation solutions as one of the promising approaches to significant energy consumption reductions in buildings.
Research limitations/implications
This review study is solely limited to the revisited research directions.
Originality/value
This study successfully identifies a number of decision making tools related to building refurbishment and an initial research path in favor of building energy consumption reductions.

Abstract
Purpose
A comprehensive literature review was conducted to identify the lean principles and the challenges of building refurbishment. To have an in-depth investigation of the application of lean principles to address the challenges of refurbishment projects, ten expert interviews following a qualitative research approach were utilised in this research. Data were analysed using manual content analysis to derive the framework.
Design/methodology/approach
The refurbishment of buildings has attracted the attention of the present construction industry. However, uncertain project characteristics, information deficiency, limited space for construction activities and less stakeholder involvement make it complex. Since the lean concept effectively deals with complex and uncertain projects, this study focusses to investigate the application of lean principles to overcome the challenges of refurbishment projects in Sri Lanka by developing a framework.
Findings
It was found that the five main lean principles of customer value, value stream, value flow, pull and perfection are appropriate for building refurbishment projects in Sri Lanka. Precise identification of clients and end-users, value adding and non-value adding activities, interruptions and stakeholder communication chains, setting scope, examining the possible technologies and taking measures to deliver the exact product to ensure the successful application of lean principles for refurbishment projects. Further, 27 benefits of five lean principles were identified which can be used to address the 13 identified challenges of building refurbishment of projects. Finally, a framework has developed portraying the application of lean principles in building refurbishment.
Practical implications
The framework developed is beneficial for the building refurbishment project team to address the barriers of refurbishment projects by applying lean principles.
Originality/value
This framework can be used as a guideline for the implementation of building refurbishment projects by addressing their challenges with lean principles.

Abstract
Purpose
The purpose of this paper is to analyse the use of building refurbishment productivity and sustainability indicators among construction contractors.
Design/methodology/approach
Theories of organisational culture and incentives predict that contractor size affects dependency on routines and the implementation of company policies on site. Eight semi-structured interviews were conducted with three general or site managers of small and medium enterprises (SMEs) and five site managers of large contractors involved in housing and office refurbishment projects in Sweden.
Findings
Both SMEs and large contractors track resource use on refurbishment sites. Resource use is measured through cost recording systems and a few area-based key indicators. SMEs may have sustainability policies, but routines derived from such policies were weak on site. However, for SMEs, refurbishment technology choices are often made by the client’s designer, and sustainability requirements are included in the contract specifications. For large contractors, sustainability policies are more developed and are reflected in site routines. Large contractors are usually public companies with stakeholders who expect such routines.
Practical implications
Contractors that develop strategies for increasing productivity and sustainability can benefit from a deeper understanding of implementation issues. The outcome of this paper is useful while designing new indicators and building certification schemes.
Originality/value
Much has been written about key performance indicators for construction, but little attention has been paid to indicators for building refurbishment, or the use of measurement routines.
