Abstract

Purpose

From the 2000s onward, construction practices of urban residential buildings in China have shown a material transformation from clay brick to aerated concrete block. Moreover, the consumption of insulating materials for buildings has been increasing due to the new requirements in building energy-saving standards. This transformation and the increased consumption of insulating materials might have a vital impact on a building’s thermal comfort and its associated energy flows. Therefore, the purpose of this paper is to investigate the indoor thermal performance of urban residential buildings built with different materials and further discuss the correlations between indoor thermal comfort and the associated energy input.

Design/methodology/approach

This study investigated four residential buildings selected from four residential communities located in the cold climate zone of China. The Integrated Environment Solutions program was used to evaluate the thermal comfort levels and to quantify the operational energy consumption of the case study buildings. Additionally, the University of Bath’s Inventory of Carbon and Energy database was used to estimate the embodied energy consumption and CO2 emissions.

Findings

The study found that materials transition and increasing consumption did not necessarily improve indoor thermal comfort. However, the materials transition has significantly decreased the embodied energy consumption of urban residential buildings. Furthermore, the increased utilization of insulating materials has also decreased the heating and cooling energy consumption. Therefore, overall, the environmental impacts of urban residential buildings have been reduced significantly.

Practical implications

In the future, residential buildings completed in the 1990s will need regular maintenance, such as adding insulation. Residential buildings completed based on the latest energy-saving requirements should optimize their ventilation design, for example, by increasing the ventilation rate and by reducing solar heat gains in the summer.

Originality/value

This paper investigates the effects of the materials change on thermal comfort levels and the environmental impacts of urban residential buildings in the cold climate zone of China, as these have not been the focus of many previous studies.

Abstract

Purpose

The purpose of this paper is to explore the role of the housing market in the monetary policy transmission to consumption among euro area member states. It has been argued that the housing market in one country is then important when its mortgage market is well developed. The countries in the euro area follow unitary monetary policy; however, their housing and mortgage markets show some heterogeneity, which may lead to different policy effects on aggregate consumption through the housing market.

Design/methodology/approach

The housing market can act as a channel of monetary policy shocks to household consumption through changes in house prices and residential investment – the housing market channel. The authors estimate vector autoregressive models for each country and conduct a counterfactual analysis to disentangle the housing market channel and assess its importance across the euro area member states.

Findings

The authors find little evidence for heterogeneity of the monetary policy transmission through house prices across the euro area countries. Housing market variations in the euro area seem to be better captured by changes in residential investment rather than by changes in house prices. As a result, the authors do not find significantly large house price channels. For some of the countries however, they observe a monetary policy channel through residential investment. The existence of a housing channel may depend on institutional features of both the labour market or with institutional factors capturing the degree of household debt as is the loan-to-value ratio.

Originality/value

The study contributes to the existing literature by assessing whether a unitary monetary policy has a different impact on consumption across the euro area countries through their housing and mortgage markets. The authors disentangle monetary-policy-induced effects on consumption associated with variations on the housing markets due to either house price variations or residential investment changes. The authors show that the housing market can play a role in the monetary transmission mechanism even in countries with less developed mortgage markets through variations in residential investment.

Abstract

Purpose

Residential crowding and underlying causes of crowding have been changing across the globe over time. The aim of this paper is to examine the dynamics of housing consumption and residential crowding in Hong Kong.

Design/methodology/approach

While the two‐step Engle‐Granger co‐integration approach based on an error correction model (ECM) is used to test for long‐run relation and short‐run dynamics of housing consumption, the study also uses a multivariate regression model to analyze the factors affecting residential crowding. Along with other variables in previous literature, the study introduces a new institutional factor, i.e. land supply, into the model that analyzes these two issues over a time span of 25 years.

Findings

The study's results suggest that many households in Hong Kong still have inadequate housing, and residential overcrowding is a serious issue. Coupled with market forces (e.g. income, housing price, household size), the new land supply factor noticeably has exerted significant influence on the two subject issues under investigation.

Practical implications

The paper provides policy implications that to address such deficiencies, the government should change its current land supply policy. A policy shift is recommended away from its “high‐land price” policy towards comprehensive developments in outer urban areas. This institutional change should help improve housing consumption in the territory overall.

Originality/value

This study adds knowledge to previous works in analyzing residential crowding and its underlying causes over the years, rather than in a particular point in time. It is also the first of its kind in Hong Kong.

Abstract

Purpose

The Gaza Strip in Palestine is suffering from a shortage of water and energy. To manage the current situation and address future issues, practical approaches need to be adopted to enhance water and energy efficiency. The purpose of this paper is to elicit professionals’ perceptions of the drivers affecting water and related energy consumption in residential buildings in the Gaza Strip.

Design/methodology/approach

In total, 19 drivers were identified from previous research and modified according to the results of a pilot study. These drivers were ranked under a Relative Importance Index (RII). A questionnaire survey was then administered and non-random purposive sampling used. The population of this study comprised stakeholders, including the United Nation Refugee Work Agency, Gaza Strip Governorates Municipalities, and the Coastal Municipalities Water Utility.

Findings

The results of all drivers (i.e. RII=71.43 per cent, mean=3.57) indicated that the respondents agreed about which drivers were affecting water and energy consumption. The sign Test-value was a positive 4.55 and the p-value was 0.000 (i.e. smaller than the level of significance a=0.050). The means of these drivers differed significantly and were greater than the hypothesised value of 3. Accordingly, it was concluded that the drivers investigated significantly affected household residents’ consumption of water and energy in residential buildings. The study revealed that climate changes, knowledge of how to conserve water and energy and household size were the most important drivers affecting household residents’ consumption of water and related energy in residential buildings.

Practical implications

The study will assist the parties concerned about water and energy use to be aware and understand the drivers affecting water and related energy the consumption in order to provide household residents with the necessary knowledge to ensure conservation and sustainability. Although this study related to a narrow geographical area in Palestine, the findings could be useful to similar locations in the Middle East and Africa.

Originality/value

This research demonstrates the drivers affecting water and related energy the consumption in residential buildings in the Gaza Strip which is considered the first study in Palestine and in the region. The study provides a useful platform for the development of appropriate water and energy strategies in Palestine and other similar geographical locations in the Middle East.

Abstract

Purpose

The purpose of this paper is to present the efficiency of electricity use and potential of electricity reduction at 12 residential colleges located at University of Malaya Campus, Kuala Lumpur.

Design/methodology/approach

The work presented applies an energy audit when energy consumption data were collected and analysed for a five‐year period. The total savings of electricity used at residential colleges were identified through the difference between average total energy use in a year (kWh) and minimum electricity usage.

Findings

The study finds that residential colleges with special features of building layout and arrangement performed better with regard to electricity consumption due to the prior group's superior utilisation of day lighting and natural ventilation. The floor area of the rooms, volume, density, enclosure and facade design, including window design, window area, and window‐to‐wall ratio also influenced the total electricity usage of the residential college buildings. Also, through adaptation of the corridor area to include more natural ventilation and daylight, approximately 40 to 90 percent of average electricity usage could be conserved in a year.

Research limitations/implications

The methodology is limited to energy audit for a five‐year period of metered data and walk‐through analysis.

Practical implications

The findings raised some issues related to thermal comfort of the residents.

Originality/value

The study can be used as baseline data for a tropical region particularly on current electricity usage and potential of energy conservation in residential building.

Abstract

Purpose

This paper aims to obtain accurate forecasts of the hourly residential natural gas consumption, in Egypt, taken into consideration the volatile multiple seasonal nature of the gas series. This matter helps in both minimizing the cost of energy and maintaining the reliability of the Egyptian power system as well.

Design/methodology/approach

Double seasonal autoregressive integrated moving average-generalized autoregressive conditional heteroskedasticity model is used to obtain accurate forecasts of the hourly Egyptian gas consumption series. This model captures both daily and weekly seasonal patterns apparent in the series as well as the volatility of the series.

Findings

Using the mean absolute percentage error to check the forecasting accuracy of the model, it is proved that the produced outcomes are accurate. Therefore, the proposed model could be recommended for forecasting the Egyptian natural gas consumption.

Originality/value

The contribution of this research lies in the ingenuity of using time series models that accommodate both daily and weekly seasonal patterns, which have not been taken into consideration before, in addition to the series volatility to forecast hourly consumption of natural gas in Egypt.

Abstract

Purpose

Since 1989, the efficiency of heat production has increased remarkably, and heat and water consumption have decreased significantly. This is largely due to the liberalization of prices (within 15 years heating prices have increased 25 times, water charges 50 times), legislative changes and the improved quality of administration of residential buildings. The purpose of this case study is to describe actual interventions and experiences from Slovakia's older residential houses. Some associations' efforts in relation to building management of housing estates have achieved such improvements, which are also instructive to advanced countries.

Design/methodology/approach

The paper utilises a case study approach.

Findings

On the basis of detailed analyses of housing estates it can be concluded that their physical condition, due to various structural defects and technical shortcomings, poor workmanship and neglected maintenance, is worse than that corresponding to their age, particularly in panel housing estates. A reduction in energy consumption in existing housing estates can be achieved mainly by taking the measures outlined. A reduction in energy consumption in residential buildings can be achieved effectively only in terms of real economic parameters. Artificially maintained low energy prices did not motivate residents to reduce heat or water consumption. Now that prices have been brought closer to those in other EU countries, the economic effectiveness of rationalization measures for reducing costs in heating residential buildings can be evaluated more objectively. Rationalization measures aimed at reducing energy consumption have proved successful. Building administration associations have transformed to a great extent.

Practical implications

The paper is a very useful source of information and impartial advice for associations wishing to achieve a necessary level of production and supervision.

Originality/value

This paper fulfils an identified information/resource need and offers practical help for the effective management of housing estates.
