Key Findings

01The developed Energy-efficient Building Environmental Quality Evaluation Framework is reliable and valid.
02The framework can effectively identify occupant comfort levels in energy-efficient buildings.
03Problems affecting occupant comfort are often related to the building envelope, particularly shading and window features.

Application

Design takeaway

When designing energy-efficient buildings, pay close attention to the building envelope's shading and window specifications, as these directly influence occupant comfort.

How to apply

When designing or retrofitting buildings, use a structured evaluation approach to assess how envelope features affect occupant comfort and energy performance.

Project actions

01Consider how your design choices for building exteriors will affect the people using the space.
02Develop a method to measure or assess user comfort in relation to your design features.

Method & Evidence

AimTo develop and validate a framework for evaluating the impact of energy-efficient building design features on occupant comfort in hot and humid climates.

MethodFramework Development and Validation

ProcedureA new evaluation framework, the Energy-efficient Building Environmental Quality Evaluation Framework, was developed. This framework was then applied and tested in three energy-efficient office buildings in Malaysia. Statistical analysis using SPSS was performed to assess the reliability and validity of the framework.

ContextOffice buildings in hot and humid climatic regions.

Variables

IVBuilding envelope features (shading, window design)

DVOccupant comfort level, energy efficiency

CVBuilding type (office), climate (hot and humid)

Strengths & Limitations

Strengths

+Development of a novel evaluation framework.
+Validation of the framework using statistical methods.

Limitations

It can be challenging to isolate the impact of a single design feature on user comfort due to many interacting factors.

Reliability & validity

The study reports high reliability and validity for the developed evaluation framework, as determined by statistical analysis using SPSS.

Think critically

How can the principles of optimizing building envelopes for comfort and energy efficiency be applied to other design contexts, such as portable electronic devices or vehicle interiors?

Design Principles

"Optimize building envelope elements for both energy efficiency and occupant well-being."

For designers and engineers, this highlights the critical link between physical building elements and the human experience within. Optimizing the building envelope is not just about energy savings but also about creating a more comfortable and productive environment for occupants.

What This Means for Your Design

This study shows that how you design the outside walls and windows of a building really matters for how comfortable people feel inside and how much energy it uses, especially in hot places.

How to use in your project

1.Use the findings to justify design decisions related to building envelopes, materials, or user comfort in your design project.
