Abstract:
In an era of rapid development, the great need for energy conservation has emphasized
the need to establish sustainable practices in the construction Projects. Many countries have
responded by developing regulations and techniques to improve the energy efficiency and
longevity of existing Buildings. However, the upfront costs associated with these solutions
often scare decision-makers and force them to look for alternative ways, even if they result
in higher operating costs. To address this problem, ongoing research thoroughly
investigates how different energy load reduction strategies, including active and passive
approaches, can affect the overall cost dynamics of Existing Buildings over time. Focusing
on a warm and dry climate, guided by the principles of environmentally conscious
construction, several strategies including external wall insulation with polyurethane,
external shading with horizontal single panels, HRBLUE2 windows, R10 polystyrene roof
insulation, night ventilation and LED lighting systems were carefully selected after
planning and evaluation. The goal is to extract the optimal combination of these strategies
to find the least energy load. Their effectiveness in controlling heat was evaluated by
simulations performed with Design Builder V7.0.2 software. In addition, the study aimed
to calculate the life cycle costs of these energy strategies. The life cycle costs of all
identified strategies were thoroughly calculated. Recommendations include a comparative
combination of strategies that effectively reduce the energy load, a combination of
strategies with minimal life cycle costs, and finally a selection with optimal normal
performance specifically adapted for the Research and Display environment.
