“…Even if more than one indicator analysed, no study has examined the effect of urban built form at the same time with density and energy holistically. It is crucial to give information about urban built form as it alters the microclimatic conditions (Emmanuel and Steemers, 2018) that consequently affect building energy consumptions (Lee and Jeong, 2017). There seems to be a lack of a unified set of guidelines to communicate urban density indicators and their relationships with urban built forms.…”

The paper introduces a novel indicator of urban built form termed Form Signature. Generic models of four urban built forms are developed, including pavilion, terrace, court and a newly introduced tunnel-court is used to compare and contrast their land-use performance and density characteristics. Selecting plot ratio and site coverage as the most popular and appropriate density indicators, the simultaneous relationship to each of the considered urban built forms is shown graphically with the number of storeys, plan depth and cutoff angle as the main variables of interest. For existing urban areas, the resulting graphs provide a robust tool for statistical analysis of contexts such as climate, economy, energy and crime potential and establish their relationship to form and density. To show the value of the contribution, analysing 32 case studies from 19 cities in different global locations showed an insignificant relationship between climate and form/density of urban areas, whilst practically depicting that urban areas built in court form acquire higher cutoff angle compared to terrace form urban developments. For planning the future urban areas, the resulting relationships provide application-oriented urban planning tool to facilitate the most effective land-use method in order to achieve sustainable cities. Examples showing the potential of the tool for future statistical energy and social analysis of urban areas are provided. Finally, a relative comparison shows that the newly-introduced tunnel-court form achieves the greatest density while pavilion achieves the lowest.

“…In addition, climate-responsive designs also have an impact on energy-efficient uses. The characteristics, as well as the form and the pattern of buildings or cities may influence the formation of microclimates, resulting in energy consumption changes (Lee, 2017). For building as an example, it occurs because the design of the building's inner space conditions also affects the energy use in the building, based on the microclimate response (Alwetaishi, 2016;Strelková, 2013;Pisello, 2015).…”

In step with economic growth, Pontianak City continues developing its physical development. From an environmental perspective, physical development that does not pay attention to the environment may make air temperature rise and create inconvenience to human. The purpose of this study is to evaluate the tendency in the built/physical environmental aspects that have the possibility of influencing the microclimate in the urban center, regarding the trade area in Pontianak City. Built environmental aspects such as building density, building height, materials, etc. are described and then simulated towards the existing climate elements such as temperature, humidity, solar radiation, cloud cover, and others. The simulations used three-dimensional software ENVI_MET version 4. From findings, it can be seen that the built environment characteristics can affect the microclimate condition. From the simulations, the dominant temperature differences may occur in such built environment conditions such as density, dimensions, location, material, and vegetation closure.

“…Besides the physical condition of a building, such as the building type [ 5 ], construction [ 6 ], and HVAC (Heating, Ventilation and Air Conditioning) system [ 7 ], and its energy consumption patterns (ECP) [ 8 , 9 ], such as energy-use behavior and lifestyles, numerous studies have observed that the surrounding environment is critical in influencing the building heating energy consumption ( Figure 1 ) [ 10 , 11 , 12 ]. Urban morphology and climatic conditions have been identified as key environmental factors that affect the overall heating demand in cities [ 13 , 14 , 15 ].…”

“…Martins et al [ 14 ] observed that aspect ratio and building height accounted for almost 50% of the overall impact on heating demand. Furthermore, floor area ratio and shape factor are also energy-related urban morphological parameters [ 11 , 17 ]. The impact of climatic conditions has been widely discussed as well.…”

This study aims to acquire a better understanding of the quantitative relationship between environmental impact factors and heating energy consumption of buildings in severe cold regions. We analyze the effects of five urban morphological parameters (building density, aspect ratio, building height, floor area ratio, and shape factor) and three climatic parameters (temperature, wind speed, and relative humidity) on the heating energy use intensity (EUI) of commercial and residential buildings in a severe cold region. We develop regression models using empirical data to quantitatively evaluate the impact of each parameter. A stepwise approach is used to ensure that all the independent variables are significant and to eliminate the effects of multicollinearity. Finally, a spatial cluster analysis is performed to identify the distribution characteristics of heating EUI. The results indicate that the building height, shape factor, temperature, and wind speed have a significant impact on heating EUI, and their effects vary with the type of building. The cluster analysis indicated that the areas in the north, east, and along the river exhibited high heating EUI. The findings obtained herein can be used to evaluate building energy efficiency for urban planners and heating companies and departments based on the surrounding environmental conditions.
