Simulation of Different Light Well Typology by using Daylight Rules of Thumb under Overcast and Intermediate Skies without Sun

The daylight conditions that are fit for an interior can be easily achieved by applying the simple and comprehensive principles, the daylighting rules of thumb in the process design. In architecture, these rules can be expressed in a different kinds of modes and are divided into categories that based on the parameters which constitute them. Since daylighting is the control admission of natural light, one of the categories can be the light well topology. Thus, an opening plays an important role in influencing the effectiveness of daylight distribution in building. One of the categories is light well typology. This study was conducted using an existing sample of single side opening and two side opening light wells with the comparison of additives to light-well typology under under overcast and intermediate skies without sun also to proposes daylighting rules of thumb for light wells. There are several types of light wells simulated for daylighting performances in this study. Light well models were simulated by conducted using IES_VE application software. Regression analysis was then carried out to find correlation between the measurements obtained in the daylighting simulation and the calculations derived from an established daylighting formula. Thus, existing daylighting formula is modified to create new daylighting rules of thumb for light wells with reflectance mirror in single storey terrace houses. These simple equations can serve as rules of thumb to help architects and engineers in calculating daylight levels for different light well designs.

Modelling of property market: the structural and locational attributes towards Malaysian properties

House acts as a basic shelter icon for all mankind. In recent years, property value has never stopped receiving attention in the market and has remained the topic of discussion and research on reputable property platforms and all around the world. Residential properties in Malaysia experienced significant appreciation in recent years and this creates anxiety among people. The real factors behind the tremendous rise of property prices in Malaysia however, are yet to be discovered. Structural and locational attributes are frequently discussed and have received uncountable attentions from the whole nation. This study intends to ascertain the factors affecting the property prices. The area of study comprised double storey terrace houses in Mukim Rawang, Selangor, Malaysia. Documentary analysis is conducted in this research with the real transaction data collected from JPPH. Using the regression analysis, various factors were included in the models to capture the particular effects on property values. In particular, built-up area is the most significant structural attribute; whereas shopping centre is the most significant locational attribute in determining the property prices. This paper serves as a guide for the developers and house buyers in decision-making for development and investments.

Review of Thermal Performance: A Terrace House in Melaka, Malaysia

A field study of residents’ thermal comfort in a naturally ventilated intermediate single storey terrace house was carried out at Merlimau, Melaka. An intermediate single storey terrace house was chosen as a case study and indoor thermal condition measurements were recorded for three days. The indoor ambient temperature, relative humidity and air speed were measured using on-site monitoring equipment to evaluate the thermal performance of this house. A questionnaire survey was also conducted involving all occupants to determine their thermal comfort perception of the same case study house. The aim of this study is to analyse the indoor thermal condition of an intermediate single storey terrace house in order to propose architectural features to climatically adapt to the local climate. In naturally ventilated condition, results showed that this house is thermally uncomfortable and the indoor thermal condition was between 2.7°C to 5.9°C higher than suggested temperatures stipulated in ASHRAE Standard 55. Consistently, five out of eight occupants or less than 80% of occupants voted the house as thermally acceptable according to ASHRAE Standard 55.

Thermal Performance Comparison between Single and Double Storey Terrace Houses in Melaka, Malaysia

Over the past decade many studies were conducted to investigate the thermal performance of terraced houses in Malaysia. It was found that this housing typology failed to address the need for thermal comfort and alternatives to the narrow frontage with deep plan have been proposed with simulated good thermal performance. Although this is good progress for new generation of terraced houses, millions of units of terraced houses are still in use and new units with the outdated existing plans continued to get built due to consistently very high demand due to progressive urbanisation and rapid economic developments. Therefore, it is imperative that the thermal comfort issue for existing terraced houses is dealt with and through this paper a comparison between single and double storey terraced houses is made through analysis of indoor environmental monitoring (ambient temperature, relative humidity and air velocity) of two (2) selected case studies in Merlimau, Melaka. Contrary to popular belief, it is found that there is no statistical difference between both sets of indoor temperature and relative humidity between the case studies. This finding is indicative of the consistent and stable temporal temperature highs and lows in a 24 hour cycle despite the difference in indoor volume and distance between the ground floor and the roof cavity. Much of the reason is due to the materiality of the terraced houses construction and unsealed and uninsulated building envelope. Therefore, further research into improving the thermal performance of existing terraced houses of any typology have to be conducted to allow thermal comfort and to reduce reliance on high energy consuming air-conditioning.

Housing Space Quality towards Quality Of Life: A Case Study of Double Storey Terrace Houses

The success of every housing area is determined by its user satisfaction level, living there. The quality of the house, its spaces within the unit, housing neighbourhood and green open space can directly influence the quality of life. Limitation of space following high land cost in an urban area, evaluation of the housing environment as a whole including the green open space needs to be studied as it affects the residents’ satisfaction level. This study concentrates on spaces within a housing area to evaluate the residents’ level of satisfaction of the Taman Melati Mastika (TMM), Kuala Lumpur and to understand how they perceived their quality of life through the housing environment and the availability of green open space. Thus, this research was carried out through site observation and analysis, and self-administered questionnaire survey. 247 questionnaire surveys were distributed to the residents of TMM and (n=62) responded. When focused on the housing unit, this study provides insight on the types of outdoor spaces (front yard-front lane and backyard-back lane) and their elements and utilization, and quality of housing spaces toward users’ quality of life in TMM, Kuala Lumpur. On the green open space, the assessment of the quality of life is based on three factors that are the safety level of the neighbourhood and park, health issues related to housing environment and park as well as the satisfaction on the housing amenities and park facilities. The result of this study suggests that the residents are satisfied with the existing spaces within their compound and adjacent to it and this lead towards the overall satisfaction living in the area. The quality of space and good utilisation of housing areas can lead towards a better quality of life in the Terrace housing area is confirmed.

Evaluation of Energy Efficiency for Residential New Construction (RNC) Single Storey Terrace House

The impermanence changing of the climates that cause many natural disasters these days has raised the attention of us about the importance of greening towards our planet. The building sector has been verified as the major part of the global solutions. Hence, Green Rating Tools are recommended internationally to guide the developers and public in designing and developing green buildings in order to reduce the negative impact towards human health and environment due to increasing use of natural resources. The research on energy efficiency of Residential New Construction (RNC) was successfully done and analyzed by using the DIALux software and light illumination calculations.

Critical Factors Affecting Double Storey Terrace Houses Prices in Bandar Baru Bangi

Everybody needs a house as shelter, either by renting or owning one. In order to have a good place called home, the location normally will be the priority in the list. Recently Bandar Baru Bangi which is recognized as Malay Elite Town has the significantly shown an increase in house prices starting from the mid 90's. Thus, this area is the main focused of the research. The increase in the prices for double storey terrace house in major areas in Malaysia has been a concern for property buyers, especially in developing areas. There are twenty one factors listed for the research and the factors are grouped into three main groups; internal, external and capitalist factors. The survey analysis by the developers who handles the double storey terrace house sales in Bandar Baru Bangi for past years indicates that that the capitalized factor such as supply and demand, market conditions, and access to public transport and distance to the city centre are the factors influencing the price of double storey terrace houses in Bandar Baru Bangi.

Solar Chimney Geometry for Stack Ventilation in a Warm Humid Climate

Natural ventilation is a well known strategy to improve indoor air velocity and reduce indoor temperature. It is the main criterion to achieve thermal comfort in terraced housing in Malaysia. In hot and humid climates, one drawback to single sided ventilation is that the wind effect is not well captured, which in turn, increases the use of mechanical cooling. Therefore, it is important to understand and consider the use of the solar chimney as a stack induced ventilation strategy for a single sided ventilated room. This study investigates solar chimney geometry to improve indoor air velocity and to reduce temperature in order to achieve comfort ventilation in hot and humid climates. An experiment was carried out to measure the natural ventilation rate of a single master bedroom in a typical single storey terrace house. The investigation was assisted using FloVent 5.1, a computational fluid dynamic simulation program which was first validated by comparing simulated results with field measurements taken on site. The results of the experiment showed that an optimum solar chimney geometry model of 3.5 m height, 3.5 m length and 1 m width gap could increase the indoor air velocity by more than 30% when compared with the standard field study model. This effect is significant towards improving air velocity for thermal comfort performance in conventional terraced housing through passive natural ventilation. In conclusion, optimisation and modification of solar chimney geometry can further improve the air velocity for increased ventilation and thermal comfort.

A model for passive solar housing density

SYNOPSIS The problem posed was to examine the implications of density and overshadowing for passive solar housing in Milton Keynes New Town, England. Land use and solar data were fed into a simple housing layout model which output the performance of typical house types, frontages and densities. Narrow frontages and single storey houses suffer less from overshadowing. Many of the failures could be made to work with different land-use allocations, even three storey terrace houses. Semi-detached houses fare badly because their wider plots reduce spacing. Land use policies should take account of the relationship between plot dimensions, density, the proportions of site given over to different uses and their effects as constraints on the built form. It is possible to vary the parameters in order to review the options open to a designer under different conditions. Or a local authority could examine the implications of different land-use policies on passive solar housing.
