Project Introduction

The National Library of Oman is one of the country’s most iconic cultural institutions. Situated in Muscat’s hot, arid climate, the building presented several energy challenges; particularly in cooling demand and the integration of natural and mechanical ventilation systems. This study was carried out with the goal of improving thermal performance, reducing energy use, and enhancing user comfort, all while adhering to the core principles of sustainable design.

Project Objectives

Analyze the building’s cooling demand based on real local climate data
Evaluate the effectiveness of natural ventilation and its interaction with mechanical systems
Optimize HVAC system sizing through dynamic thermal modeling
Reduce overall energy consumption and operational costs
Improve indoor thermal comfort for occupants

Approach & Tools

To model the building’s energy behavior, we used DesignBuilder, a powerful simulation platform built on the EnergyPlus engine.
This allowed for detailed thermal and environmental analysis, including:

Heat transfer between interior and exterior zones
Airflow patterns throughout the building
Thermal performance of envelope materials
Impact of building orientation and shading devices on cooling loads

Simulations helped identify inefficiencies and guided the development of tailored strategies to improve energy performance, particularly during peak summer months.

Key Performance Indicators (KPI)

Cooling Demand: Estimation of cooling load requirements during peak hot seasons
Airflow & Natural Ventilation: Assessment of airflow efficiency through optimized window placements and airflow paths
Ventilation Rate: Evaluation of indoor air quality through ventilation effectiveness metrics

Performance Highlights

Cooling Load Reduction: Optimized design strategies led to an 18% decrease in annual cooling energy use
Improved Ventilation: Natural airflow efficiency increased by 25% through better window placement and passive ventilation techniques
Ventilation Effectiveness: Enhanced indoor air quality and thermal comfort through hybrid ventilation modeling

Environmental & Economic Benefits

Lowered electricity demand for cooling, contributing to reduced carbon emissions
Enhanced occupant comfort with a more stable indoor thermal environment
Extended service life of mechanical systems thanks to a more balanced hybrid ventilation approach
