Abstract

Purpose

Global warming and climate change is one of the biggest issues facing humanity in this century; its effects are felt on the highest peaks of Mount Everest to the low-lying islands in the India Ocean. This century marked the highest amount of carbon dioxide (CO2) emitted, breaking records of the past 650,000 years, and we have pushed the climate to “a point of no return”. Much of the climate contribution has been linked to humanity’s thirst for higher living standards and lifestyle, which has led to higher consumerism, depletion of earth’s resources, production of massive waste and carbon emissions. Fast forward from the sustainability agenda of Brundtland set in 1987 and the increasing demand for energy consumption to cater for the current global inhabitants, many “green” efforts have been taken by the building industry to reduce the overall environmental impact. This purpose of this study is to compare energy performance of a conventional office building with a green certified building.

Design/methodology/approach

This paper tries to bridge the performance gap by comparing measured operational energy consumption and carbon emission of Green Building Index (GBI)-certified office buildings in Kuala Lumpur, to determine whether “green buildings” are performing as intended in reducing their environmental impact.

Findings

This paper highlighted and compared operational energy consumption and carbon emissions of a GBI-certified office with a conventional office building in Malaysia. The paper also discusses the performance gap issue and its common causes, and aims to compare predicted energy and operational energy performance of buildings.

Originality/value

Initiatives such as “green” or “sustainable” design have been at the forefront of architecture, while green assessment tools have been used to predict the energy performance of a building during its operational phase. There is still a significant performance gap between predicted or simulated energy measurements to actual operational energy consumption. The need to measure actual performance of these so-called “green buildings” is important to investigate if there is a performance gap and whether these buildings can perform better than conventional buildings. Understanding why the performance gap occurs is a step in reducing actual and predicted energy performance in buildings.

Abstract

Purpose

This paper aims to raise awareness on how a simple action by the occupant can significantly influence building energy efficiency, cost and CO2 emissions to the environment. Classrooms in schools are the primary energy consumers (45.4%) due to the use of artificial lighting, despite Malaysia's tropical climate being ideal for daylight exploitation. This paper focuses on assessing the workplane daylight distribution quality and quantity in baseline and existing conditions of a typical pre-school classroom in Kuala Lumpur as a model-based exploration strategy towards nearly Zero Energy Buildings.

Design/methodology/approach

The adopted method is based on the calculation of average daylight factor (DF), daylight illuminance level (IL) and uniformity ratio (UR) parameters affected by the internal fixed drapes through computational and in situ measurements according to the requirements of the law and respective standards comprising the MS1525:2019, GBI and BREEAM.

Findings

The results show how user behaviour can turn a well-daylit area (Net Lettable Area>90%) into a poor-daylit area (NLA<5%) by sacrificing natural daylight. All the parameters' values were significantly decreased from 10% (UR) up to 88% (ADF). Full dependency on artificial lighting has imposed a total of RM18858.90 and CO2 emissions of 25,362 kg for all pre-schools' classrooms in the country per day.

Social implications

The paper develops the occupants' awareness on their contribution to climate change and global warming through the information and transparency provided.

Originality/value

The evidence indicates that a simple action by the occupant can significantly influence visual comfort, EE, cost and CO2 emissions to the environment.

Abstract

Purpose

Malaysia’s building regulation is mainly based on the Uniform Building By-Laws (UBBL) 1984 which provides guidelines on the procedures for building plans approval and other means of development control. However, the application of these by-laws varies between local authorities, as they are gazetted by different state governments. The formulation of UBBL 1984 which was originally formulated to address the need for a standardized set of building regulations for the country is now perceived as inconsistent and complex. Therefore, this research attempts to examine the discrepancies between state by-laws, particularly Federal Territory of Kuala Lumpur and national UBBL 1984.

Design/methodology/approach

Critical review of the content of the UBBL (Federal Territory of Kuala Lumpur) 1985 and national UBBL 1984 was carried out to pinpoint discrepancies between the two by-laws.

Findings

Differences between national UBBL and Kuala Lumpur By-laws fall into four main categories particularly terminology, prescriptive requirements, presence of terms and by-laws. Three editorial spelling and typing errors were also found in the national UBBL 1984. It is argued that the errors and differences lead to confusion and pose unnecessary regulatory burden to the construction industry which ultimately discourage people to disobey the rules. The identified discrepancies between these by-laws showed an urgent need to review the current building by-laws considering today’s technologies, norms and citizen needs.

Originality/value

To the best of the authors’ knowledge, this study is the first of many fruitful contributions that examine discrepancies between by-laws that govern building control matters in Malaysia. Although centred on legislation in Malaysia, the findings are relevant for governments around the world working towards improving public service delivery.
