The Potential of Vertical Extensions: A Case Study Analysis

Charles Joseph GILLOTT, Danielle DENSLEY TINGLEY, John Buick DAVISON

The University of Sheffield

As buildings are responsible for almost 40% of carbon emissions, decarbonising the built environment is key in limiting global temperature increase. With awareness of the importance of embodied carbon increasing, transition towards a circular economy within the built environment now essential. The adaptive re-use of existing buildings has a significant role to play in this through reduced material consumption and waste generation, and prolonged building lifespans. One adaptive reuse strategy, the vertical extension of existing buildings, serves to achieve this whilst meeting growing demand for space within already dense cities. This paper reviews seven instances of vertical extension in the UK and Ireland, exploring the specific motivations for, and technical details of, each. These are compared to reveal the suitability of vertical extension to a range of building archetypes, and the case-by-case variability with which both structural appraisal and remediation are required.

Approach to Holistic Energy, Comfort and Health Management in Residential Buildings with Split Air Conditioning Units


Institute for Building Energetics, Thermotechnology and Energy Storage (IGTE), University of Stuttgart, Germany

Increased temperature, intensification of the urban heat island and rising comfort requirements drive the fast-growing energy demand for space cooling. Due to multiple reasons, there are more people prefer to use mechanical cooling instead of electric fans or natural ventilation. This will not only lead to a dramatic increase in energy consumption, but also result in poor indoor air quality due to insufficient ventilation, especially in residential buildings with split air conditioning units. Occupant behaviour in this building type has a significant impact on the building energy performance and the indoor environment, but it is difficult to consider in the design phase due to the lack of accurate prediction. This study introduces a holistic approach to analyze the energy, comfort and health-related issues as well as the human-building interactions during building operation. Its outcomes will provide a sufficient basis for the development of sustainable solutions for existing and new buildings.

Assessment of the Urban Micro-Climate and Thermal Performance of a Traditional Settlement in Turkey


The University of Liverpool, United Kingdom

In the built environment, the thermal characteristics of outdoor spaces and the street networks linking them are determinants of people’s comfort and the sustainability of that environment. Gelemic is a historic village, as an earthen architectural heritage site in Turkey, located in Bursa city. Low-rise clustered wooden framed earth block structures, narrow streets with old stone pavements, and small backyards shape the authentic urban morphology. The village experiences a Mediterranean climate. This research investigates the outdoor and indoor thermal environments of Gelemic's architecture to identify and quantify the urban forms that create the best comfort conditions. The study considered indoor and outdoor temperature and humidity values of the present traditional and modern urban configurations. The inhabitants’ comfort levels were assessed by undertaking a questionnaire survey. Mean radiant and air temperatures, wind speed and relative humidity were measured and modelled in ENVI-met software to evaluate the existing urban design’s thermal performance.

Children aged 6 to 14 spend a large part of their time in school classrooms. The human eye in this age is evolving and is sensitive to the surrounding light conditions. For this reason, it is important to ensure that in the classrooms daylight quantity and quality requirements are fulfilled. The windows and the shading systems need to be designed to limit potential summer overheating and prevent users’ discomfort.

Recently, a rapid increase in myopia progression in children has been reported. Possible causes are still unclear, but limited time spent outdoors, insufficient access to daylight and sunlight seem to be important triggers for myopia development. Moreover, data collected during pandemic Covid 19, when people were forced to stay at home, also suggest the irreplaceable role of a quality lighting environment on the healthy development of the eye.

This study assesses the interaction of the classroom design, daylighting, and healthy eyesight.

(The Role Of Origami Technique In Sustainable Building Systems)


AL-MUTHANNA UNIVERSITY, Collage of engineering , Department of Architecture

Nature is the source of inspiration for art and architecture and design principles such as (linear construction of the tree, shell construction in both the egg and shell, the taut construction of cobwebs). Modern use of the word "Origami" as an umbrella term for folding practices regardless of their culture of origin, the goal of which is to transform a flat sheet of paper into its final shape through sculpting and folding techniques. Nature reveals the principles of rhythm and harmony, which are the principles adopted by the Origami design through its inspiration from the organic theory. To prove this, the research adopted the descriptive analysis method to come out with conclusions, the most important of which is that the Origami design achieves the elements (durability, flexibility, and beauty), which are important indicators of sustainability
