Built environment is responsible for 60% of total energy consumption in European countries and 128 million BOE of primary energy in Belgium. The average energy consumption in the residential buildings of Belgium is 70% higher than the EU average and stands at 348 kWh/m2/year. Energy Performance Building Directive (EPBD) provides guidelines for energy performance analysis of buildings in Belgium. In this study, a holistic approach has been adopted to analyse the building stock of Liege, Belgium. This analysis is based on ‘General Socio-economic survey 2001’ and ‘Housing quality survey 2006 in Walloon region’databases. It considers parameters such as buildings age, built-up area, type of heating system, type of fuel used, adjacency, insulation of roofs and walls and energy consumption etc. for an in depth analysis. This study concludes that about 69% of buildings which are constructed before 1945 needs serious renovation towards the improvement of roof and external wall insulation level. It then successfully identifies specific areas which need detailed study to evaluate the comfort status in the existing building stock, improvement of insulation level and its effect on heating energy consumption as well as the economic analysis on energy efficiency measurements.

Indoor thermal environment monitoring has been done in 20 residential buildings of Liege city followed by questionnaire based comfort survey amongst the occupants of 85 houses in order to record their preference and expectations about indoor thermal environment in winter and spring season. It is found from the analysis that change of glazing has a minimum or even sometimes an adverse effect on the existing indoor environment due to the absence of proper insulation of the rest of the building envelope. It is observed that in winter there is a sudden drop in indoor temperature and also overheating in summer. This is due to unplanned installation of glazing which actually increases the fenestration area ratio leading to higher indoor temperature fluctuation and causes discomfort. It is also important that the occupant’s preference and expectations as well as overall assessment of indoor environment needs to be consider towards energy efficiency improvement. [less ▲]

A detailed study on the building stock of Liege urban area (Belgium) has been conducted during 2011-2012. The study is focused on historic buildings, which were constructed before 1945 and represents a very significant share (68.33%) of Liege building stock. In the Walloon region, the average heating energy consumption per year of the building stock is 408 kWh/m2 and the average heating energy consumption per year stands at 340 kWh/m2 for Liege. Hence, it is important to study existing buildings to improve the energy efficiency as well as thermal comfort standards. It is also important to understand the behaviour of these buildings and the preferred indoor thermal environment of the occupants. Keeping this in mind, the indoor thermal environment has been monitored for ten residential buildings followed by detailed interaction with the occupants to record their preference and expectations about indoor thermal comfort. It was found from the analysis that the fluctuations in the temperature of living room and bedroom with respect to outdoor conditions are a function of occupant’s age, type of heating system and fuel used. It is also found that the average energy expenditure was very high in these buildings. The study further identifies specific areas that need to be taken into consideration in order to improve the thermal comfort and energy efficiency. It put forth the argument that to improve the energy efficiency of occupied houses, occupant’s preference and expectations on thermal comfort needs to be considered for designing sustainable solutions towards improving energy efficiency.

The present paper presents a full procedure to develop an adaptive comfort model for South-East Asia. Meta-analysis on large number of observations from field surveys which were conducted in this region was employed. Standardization and bias control of the database were fully reported. Statistical tests of significance and weighted regression method applied in the analyses strengthened the reliability of the findings. This paper found a great influence of ‘Griffiths constant’ on the establishment of adaptive comfort equation and proposed an appropriate value. The adaptive comfort model generated is applicable to naturally ventilated building under hot and humid conditions of South-East Asia. The mean neutral comfort temperature (operative temperature, effective temperature, standard effective temperature) in naturally ventilated and air-conditioned building was compared and the differences have been discussed. The similar neutral standard effective temperature in both naturally ventilated and air-conditioned building proposes a new idea to implement SET* into building simulation tools to assess thermal comfort without the attention of building classification. Through the analysis, the effectiveness of behavioral adaptive actions on occupant’s thermal perception has been argued. The extended PMV-PPD model for hot humid conditions was examined and its applicability was recommended. Other comfort related issues, the differences and similarities between various adaptive comfort models were also addressed. [less ▲]

Energy, built environment and thermal comforts are closely inter-related. The unprecedented growth in building sector due to growth in population and enhanced thermal comfort standards leads to more primary energy consumption and consequently increases the green house gas (GHG) emissions to the environment. The construction industry in India is one of the largest economic activities and is growing at an average rate of 9.5% as compared to the global average of 5%. Buildings are the major consumer of energy in their construction, operation and maintenance. In India building sector accounts 30-40% of total primary energy consumption and more than 30% of electricity. While the growth is imminent, it is imperative that the developments need to happen in an environmentally sustainable manner. In this context, energy efficient building, climate-responsive building or green buildings designs have great impacts on conservation of natural resources, energy efficiency, better waste management, water use efficiency and reductions in GHG emissions. In this article, the various measures taken worldwide to reduce the energy consumption and carbon footprint of the buildings through green building approach are discussed. The present state of the green building initiatives, green building rating and certification procedures in India are also discussed. [less ▲]

Thermal performance study is one of the critical aspects of the natural ventilated vernacular buildings. Thermal comfort studies of built environment mainly focussed on two different approaches, one is heat balance approach and the other is adaptive approach. Thermal comfort survey has been carried out in 50 houses covering over 100 occupants of cold and cloudy climatic zone of North East India. This comfort study has been done in the form of long term thermal monitoring at outside and inside of a house, comfort survey based on ASHRAE thermal sensation scale for different seasons of the year. Comfort temperatures are calculated based on Humphreys and Auliciems comfort model. Neutral temperatures at which people feels comfortable in this natural ventilate buildings are obtained from the comfort survey. It has been found that the comfort temperature obtained from the Humphreys and Auliciems comfort model differs with the neutral temperatures obtained from comfort surevy. There are four major indicator like outdoor and indoor temperatures, relative humidity and clothing pattern of the peoples has direct impact on the peoples perception and acceptabilty on comfort situtaion. In this study, thermal comfort equations are developed based on these four indicator and validated with the neutral temperature obtained from comfort survey. It has been found that the comfort equation developed with all these four indicators has highest co-relation coefficient and provide the neutral temparture values very close to thermal comfort survey results. However, these equations are valid only for similar kinds of natural ventilated buildings and also for similar kinds of building functioning management of this climatic zones. It is also not appropriate to obtaine a genralized thermal comfort model as the adpation process and the expectation and perceptation of the peoples are region specific and also differs with socio-cultural norms.

Energy consumption in the buildings sector is very high and is expected to increase further due to improvements in living standard and increase in the world’s population. Incorporating appropriate solar passive features in climate responsive buildings are good options for energy conservation. This kind of building design integrates the micro-climate and architecture with human thermal comfort conditions and improves the building energy efficiency. From ancient times, people have used solar passive techniques in vernacular architectures throughout the world. However, still there is a lack of understanding, both in qualitative and quantitative aspects of solar passive techniques in vernacular architectures of North-Eastern India. A field study has been carried out to find out the various solar passive features in these naturally ventilated vernacular buildings in different bioclimatic zones of the region. The methodology of this work consists of survey of 150 households (50 houses in each bioclimatic zone) and, interacting with 300 occupants in each zone. The photographic evidences of solar passive features in these buildings are also collected. In this paper, the solar passive features related to building form and orientation, envelope design, shading, use of natural ventilation, internal space arrangements and activities of the habitants are explained for all the climatic zone of the region [less ▲]

Thermal comfort standards ISO 7730 and ASHRAE 55-2004 are based on the experimental results conducted in climatic chambers and the adaptive opportunities are usually limited in these experiments. However, in naturally ventilated buildings, adaptive opportunities are not fixed and occupants always have the liberty to modify the opportunities in order to feel comfortable. A comfort survey has been carried out in three different climatic zones of North-East India in four different seasons of a year. Climatic parameters corresponding to actual mean vote (AMV) are recorded during the survey and the values are used to calculate the predicted mean vote (PMV) using ISO 7730 calculation procedures. Results show that the PMV deviates from AMV values. A corrective term ‘adaptive coefficient’ is calculated based on PMV and AMV values and least square method to assess the different adaption used for thermal comfort. Theoretical adaptive models of thermal comfort have been developed based on these adaptive coefficients for the region. The adaptive coefficient values are varying for different seasons and also for different climatic zones. This reflects the various levels of adaptation in different seasons in a particular climatic zone. This adaptive coefficient can be used as a reference to thermal comfort assessment of the buildings and also can be used as dynamic control of the set temperature in the air conditioning system, which will results enormous energy saving. Result of this study also contributes towards the debate over the applicability of PMV model to naturally ventilated building. [less ▲]

Vernacular architecture is still very popular and constructed widely in North-East India. In this paper, the result of long-term monitoring of two vernacular houses selected one in Tezpur (warm and humid climate) and other one in Cherrapunjee (cold and cloudy climate) are presented. Long-term monitoring work includes the measurements of temperature (inside and outside house), relative humidity (inside and outside house) and illumination level (inside and outside house) for 25 days in all the seasons (January: winter, April: spring/pre-summer, July: summer/monsoon and October: autumn/pre-winter) of the year 2008. Temperatures profile across all the seasons represents strong daily and seasonal fluctuations. Formulae have been developed based on part of the monitoring data to predict the indoor maximum, average and minimum temperatures inside the same house occupied by the same family. The predicted formulae were developed based on the measured data for the month of January and July and were validated with the measured data of April and October months. It is found that the correlation coefficient (R2 value) is above 0.96 for all the six formulae for the entire monitoring period. [less ▲]

Solar passive techniques are being used in vernacular buildings throughout the world. Researchers have done extensive study on thermal performance of vernacular buildings in the different parts of the world. Vernacular architecture of North-Eastern India represents the principle of climate-responsive architecture, which still lacks experimental validation and quantitative analysis. Thermal comfort not only makes the occupants comfortable but also governs energy consumption in the building. Detailed field studies on thermal performances of typical traditional vernacular dwellings in different bioclimatic zones have been undertaken. This field study includes detailed survey of 150 vernacular dwellings, field tests and thermal sensation vote of 300 occupants on ASHRAE thermal sensation scale. Field test includes measurement of temperature, humidity, illumination level and building design parameters. Thermal performances of these vernacular dwellings were evaluated for winter, pre-summer, summer/monsoon and pre-winter months of the year 2008. This evaluation is based on ‘adaptive approach’, which is the outcome of the field studies and is now part of ASHRAE standard 55/2004 for predicting comfortable temperature of naturally ventilated buildings. This study also tried to find out the range of comfort temperature in these vernacular buildings for different season of the year. It has been found that these vernacular dwellings perform quite satisfactorily except in the winter months and the occupants feel comfortable in a wider range of temperature. [less ▲]

Vernacular buildings are region specific and governed by local climate, building materials availability and socio-economic status. So there cannot be a universal assigned standard for energy efficient sustainable buildings. ASHRAE 55-2004 and ISO 7730 also impart emphasis on more field experiments regarding naturally ventilated buildings to address the deviation of results of laboratory experiments and actual building comfort. Keeping this in mind a comfort survey has been performed in naturally ventilated buildings of northeast India during January, April, July and October months of the year 2008. The field test also includes measurement of temperature, humidity, illumination level, wall thickness, false ceiling height and dimensions of doors and windows. Thermal performances of these buildings are evaluated. The study also attempts to define the comfort status of these buildings. TRNSYS software has been used for energy simulations of these buildings. These buildings are made in SIMCAD using all the actual architectural design details. Simulations are carried out for the range of comfort temperatures found in the comfort survey. The simulation provides the results in terms of wall materials, thickness, insulation level, window and doors size and numbers and orientations of building plan required for achieving comfort range temperature inside these vernacular houses.

A field study has been carried out to evaluate the thermal comfort perception of the occupants in naturally ventilated buildings at different bioclimatic zones of North-East India. The survey also examined the adaptive behavior of the occupants in the usage of climatic control such as windows and fans to modify the indoor environment. The survey was performed in naturally ventilated buildings during the winter, pre-summer season in 2008. There were 220 occupants from 75 vernacular buildings who participated in this study and 200 questionnaire responses were collected. This study is primarily concerns on human thermal comfort from the physiological, adaptive and social convention aspects. The data collected include temperature, humidity and lighting level, as well as results from questionnaires on the occupant’s sensations of thermal comfort. This study also looks into the occupants social and cultural requirements in the vernacular buildings. Thermal acceptability assessment reveals that the indoor environment in naturally ventilated buildings are widely varied across the three bio-climatic zones and also influenced by visual, social and cultural aspects of respective zones. The upper and lower range of acceptable temperatures in naturally ventilated buildings is varied by 2 0C from neutral vote for each climate zone in both winter and pre-summer.

Building construction and operation have an enormous direct and indirect impact on the environment. The issues of sustainable building design are multi-facets and highly lateral in nature. However building sustainability largely focus on the operation of the building and construction process. Bioclimatism is a critical parameter for achieving sustainability of modern architecture. This concept takes into account the solar passive techniques and micro-climatic conditions in building design; which improves the building artificial energy efficiency and thermal comfort conditions in the built environment. Vernacular architecture based on bioclimatism concepts were developed and used through the centuries by many civilizations across the world. A questionnaire based survey has carried out at seventy five functional vernacular architecture of north eastern region of India. Temperature, humidity and day lighting data both inside and outside of the buildings are collected at all these houses. We came across some interesting findings related to bioclimatism, socio-economic status, cultural setup and sustainability in this vernacular architecture. We found that social and cultural values are closely associated with building design style and function. So these parameters needs due importance towards comfort and sustainability analysis of buildings. We also found different solar passive features available in most of these houses related to temperature control and promotion of natural ventilation. These houses are constructed using locally available building materials. Since these materials have low embodied energy and are from the same climatic zone, they fit into the local environment perfectly and represent a unique example towards achieving sustainability.

Energy, environment and architecture are closely related, the more is the energy consumption the worse is the environmental degradation. With rapid economic growth and improvement in people’s living standard, the building sector will continue to be the key energy end user. Hence energy conservation becomes a necessity rather than an option in both commercial and residential buildings and hence it becomes desirable to design climate responsive buildings by incorporating appropriate solar passive features. Climate responsive building design is a concept that integrates the micro-climate and architecture with human thermal comfort conditions. This concept takes into account the solar passive techniques, micro-climatic conditions and thermal comfort conditions that improve the building artificial energy efficiency. This fact is well supported by various studies on vernacular architecture as well as on modern architecture throughout the world. Thermal comfort not only makes the occupants comfortable but also decides the energy consumption in the building and thus its sustainability. Throughout the world, from ancient times people have used solar passive techniques that have evolved through generations. These structures got attention for detailed study among the researchers at present times. Different researchers had done extensive study on thermal performance of vernacular buildings in the different parts of the world. However, vernacular architecture of North-Eastern India which perfectly represents the principle of climate-oriented architecture still lacks experimental validation and quantitative analysis. A field study has been carried out to evaluate the thermal comfort perception of the occupants in naturally ventilated buildings at different bioclimatic zones of North-East India. The survey was performed in naturally ventilated buildings during the winter, pre-summer season in 2008.

This article examines and analyses the climates of Northeast India with respect to building design parameters: temperature, relative humidity, wind velocity/direction and solar radiation, with a view to providing passive solar design potential for the achievement of physiological comfort. It presents the work on development of bio-climatic zones for the region. The major climatic types of the region are warm and humid, cool and humid and cold and cloudy zones. A bio-climatic approach is adopted in which the comfort zone and 12 monthly climatic lines are determined and plotted on the psychrometric chart for each climatic zone. From these bioclimatic charts, the potential use of passive design strategies such as solar heating, natural ventilation, thermal mass, thermal mass with night ventilation and evaporative cooling are assessed. A total of five passive design strategies are considered. It is expected that this study will help in explaining the different passive features, which are present in traditional buildings of the region and also help the architects to design modern climate responsive energy efficient buildings in the region.

Energy and Built Environment are closely related, the more is the energy consumption the worse is the environment degradation. The use of natural lighting and the use of solar energy for heating and cooling as well as enhanced natural ventilation not only reduce the commercial energy demand but minimize the impact on environment too. Traditional buildings constructed long back in the different climatic zones of the region have a number of passive features which help in controlling the indoor environment mostly by promoting ventilation, as humidity level is alarmingly high in this region. There are exhibits of indigenous use of locally available materials and techniques to construct buildings that are adapted to local climatic conditions or even to the ethnicity of the community. Guidelines are prepared taking into consideration the different features like site, orientation & planform, building envelope and daylight for low-rise residential buildings; since these are very common in this region.
