Abstract

Purpose

The paper seeks to assess the performance of 234 public and private water and wastewater utilities from industrialized and developing countries.

Design/methodology/approach

A group of financial and operational indicators was calculated for the sample utilities.

Findings

Some indicators calculated for the private sector, represented by US and UK water and wastewater utilities, demonstrated better values compared with public utilities, such as staff number per 1,000 connections and return on equity ratio and tariffs charged. On the other hand, the percentage of unaccounted‐for water and the debt to equity ratio evidenced no advantage in private over public utilities. Further, the performance of water and wastewater utilities of developing countries and Egypt does need improvement.

Originality/value

A key problem in most of water and wastewater utilities is the absence of performance assessment tools. To this end, this research utilized indicators as a means of performance assessment of water/wastewater utilities.

Abstract

Purpose

The study aims to tackle Egypt's rising electricity consumption due to climate change and population growth, focusing on the building sector, which accounts for up to 60% of the issue, by developing new energy-efficient design guidelines for Egyptian buildings.

Design/methodology/approach

This study comprises six key steps. A literature review focuses on energy consumption and efficiency in buildings, monitoring a single-family building in Cairo, using Energy Plus for simulation and verification, performing multi-objective optimization, comparing energy performance between base and controlled cases, and developing a localized version of the Passive House (PH) called Energy Efficiency Design Criteria (EEDC).

Findings

The research shows that applying the (EEDC) suggested by this study can decrease energy consumption by up to 58% and decrease cooling consumption by up to 63% in residential buildings in Egypt while providing thermal comfort and reducing greenhouse gas emissions. This can benefit users, alleviate local power grid strain, contribute to Egypt's economy, and serve as a model for other countries with similar climates.

Originality/value

To date, no studies have focused on developing energy-efficient design standards tailored to the Egyptian climate and context using the Passive House Criteria concept. This study contributes to the field by identifying key principles, design details, and goal requirements needed to promote energy-efficient design standards for residential buildings in Egypt.
