The paper evaluates domestic energy
consumption patterns in a hot and arid climate, using a multiple case study
approach localised in Riyadh city (Saudi Arabia). Riyadh has a
characteristically hot and dry climate, and is situated in a geographical
region known for its high energy consumption and carbon emission rates. Six
properties were selected: three typical houses and three typical flats. The
objective is to analyse the average domestic energy consumption of each
property using data collected from monthly electricity bills; this usage is
then assessed with reference to user behaviour, as captured through
interviews with the occupiers of the properties, so as to assist in creating
a detailed energy use simulation model using IES-VE software. The results are
discussed with reference to both the form and fabric of the selected
properties and user behaviour, thereby identifying obvious design weaknesses,
which then serve to highlight regionally replicable energy retrofitting
solutions (i.e. shading devices, onsite renewable energy sources, and more
efficient glazing). To explore these various solutions further, additional
IES-VE simulations are conducted that suggest potential energy consumption
reductions in the range of 15% – 34%. In light of these findings, recommendations
that have the potential to be replicable across the region are given.

The paper analyses
and discusses domestic energy consumption patterns in the city of Jeddah
characterized by its hot and humid climate and its geographical location in a
global region renowned for its high energy consumption and carbon emission
rates. The selected case studies involve three typical houses and three
typical flats with the objective of analysing their average domestic energy
consumption based on (a) monthly electricity bills, (b) user behaviour
captured through interviews with the selected properties’ occupants, and (c)
detailed energy modelling and simulation using IES-VE software. Resulting
high energy consumption patterns are then discussed focussing on building
design (form and fabric) and user behaviour. Based on the identified design weaknesses,
regionally replicable energy retrofitting solutions (including, shading
devices, domestic renewable energy sources, and efficient glazing) are
explored and simulated in IES-VE suggesting an energy consumption reduction
in a range from 21% to 37%. Regionally replicable recommendations are then
proposed.

The
paper focuses on public perception of sustainable homes in a developing
economy, namely Saudi Arabia, known for its high energy consumption and CO2
emission rates. The research explores (i) public perception and knowledge of
sustainable and/or low energy homes, (ii) domestic stock typology (including
architectural style), (iii) energy consumption patterns, (iv) levels of
satisfaction with energy (i.e. HVAC) systems, (v) cultural barriers that
prevent the delivery of low energy homes, and (vi) people’s acceptance of energy
retrofitting and/or sustainable homes. For this purpose, a comprehensive
survey (n = 622) was conducted across the country. The findings reveal
limited public awareness as well as important socio-cultural barriers to the
delivery of sustainable homes, and large scale energy retrofitting of the
existing domestic stock.

Energy Consumption Patterns for Domestic
Buildings in Hot Climates Using Saudi Arabia as Case Study Field: Multiple
Case Study Analyses.
|
ملخص المشاركة:
|
The paper presents the evaluations and
debates surrounding residential energy consumption in Saudi Arabia, a country
distinguished by its fiercely hot weather and geographical position in a
global area prominent for heightened energy consumption and carbon emissions.
The cases chosen for the research comprise several residences situated in
various climatic situations across Saudi Arabia. Specifically, the case study
concerns multiple domestic buildings in the scorching, arid climate of
Riyadh, multiple domestic buildings in the hot but humid weather of Jeddah
City, and multiple domestic buildings in the hot, dry mountainous area of Al
Baha City. The main objective of the evaluation is to identify the average
energy consumption in the residential sector in Saudi Arabia, based on (a)
monthly electricity bills for each residence, (b) occupant behaviour as
determined by interviews for every chosen residence, and (c) analysis and
discussion of energy consumption through modelling and simulation for every
selected dwelling, using the IES-VE software tool. Energy consumption for the
residential division is thus explored and debated, with an emphasis on
architectural design, building materials used and occupants’ conduct. Subject
to established failures, several solutions were proposed with the objective
of reducing energy consumption; they encompass shading techniques, renewable
energy techniques, and efficient glazing. The proposed solutions were
assessed by remodelling every residence using IES-VE, and the outcome was a
decrease in energy utilisation, varying but reaching 37%, subject to local
weather circumstances. The regional, financial and environmental benefits of
the energy saving that would result from these measures being implemented for
existing dwellings across Saudi Arabia were then presented.
