Modular buildings are those built using prefabricated volumetric units called modules. Due to modules being connected to each other at discrete locations, discontinuous structural systems are formed, where diaphragm discontinuity is a key issue and could result in diaphragms that are flexible.
The building sector is responsible for a significant proportion of a nation’s greenhouse gas emissions. In an attempt to mitigate these emissions, industry and government have been mainly focussed on reducing operational emissions associated with buildings, leaving the embodied emissions largely ignored.
During summer heatwaves, heat load exacerbates in urban heat islands (especially in hot climates) and threatens public life in cities. This paper examines the links between urban microclimates, outdoor thermal discomfort and public life through an exploratory case study.
It is an increasing challenge for building designers in the 21st century to provide for thermal comfort at minimum energy cost by taking into consideration both the current and the future warming climate. Most previous studies have focused on thermal comfort in non-residential buildings under current climatic conditions.
This note presents a method to decompose life cycle inventories derived from integrated and mixed-unit hybrid life cycle assessment. The approach extends the decomposition method described by Wiedmann by diferentiating between impacts from industries, products and processes.
Evaluating building design options with a focus on simultaneously minimising life cycle greenhouse gas emissions (GHG) and life cycle cost (LCC) is difficult due to a lack of comprehensive and accessible tools. An integrated approach where life cycle GHG and LCC performance can be balanced is essential in order to optimise a building's overall life cycle performance.
Buildings are major consumers of energy for heating and cooling. The number of buildings is growing rapidly with demand for energy. To reduce consumption, governments worldwide have implemented codes, standards, and building practices.
The Building Sustainability Index (BASIX) assessment tool estimates the operational energy consumption and GHG emissions from new residential developments based on information available at the building design stage. However, post-occupancy energy consumption can be different from the estimated figures at the design stage.
Chloride ion penetration in concrete is one of the major causes of deterioration of reinforced concrete structures by depassivation of reinforcing bars. Since testing of the natural chloride penetration is time consuming, utilising an accelerated test method is more desirable.
This paper presents a performance framework for modular construction. Modular construction is a method of construction that uses factory-produced building units called modules that are delivered as components, parts or whole buildings to be erected on site. The particular aspect of performance discussed in this paper is construction performance.
