Abstract

In current research, building modelling and energy simulation tools were used to analyse and estimate the energy use of dwellings in order to reduce the annual energy use in multifamily dwellings. A three-story residential building located in Kabul city was modelled in Revit and all required parameters for running energy simulation were set. A Total of 126 experiments were conducted to estimate annual energy loads of the building. Different combinations from various components such as walls, roofs, floors, doors, and windows were created and simulated. Ultimately, the most energy efficient option in the context of Afghan dwellings was figured out. The building components consist of different locally available construction materials currently used in buildings in Afghanistan. Furthermore, the best energy efficient option was simulated by varying, building orientation in 15-degree increments and glazing area from 10% to 60% to find the most energy efficient combination. It was found that combination No. 48 was best option from energy conservation point of view and 120-degree rotational angle from north to east, of the existing building was the most energy-efficient option. Also, it was observed that 60% glazing area model consumed 24549 kWh more electricity compared to the one with 10% glazing area.

Highlights

The energy efficiency of buildings is a much debated and research area in Architecture, Engineering, and Construction (AEC) sector nowadays
Total world energy use is anticipated to increase by almost 32% and CO2 emission is projected to grow by approximately 16% until 2035 [4,5]
Numerous software tools have been developed in energy assessment in the construction industry

Summary

Introduction

The energy efficiency of buildings is a much debated and research area in Architecture, Engineering, and Construction (AEC) sector nowadays. It plays an important role in impacting environment, determining the life-cycle cost of projects, helping carbon reduction and global warming and ensuring sustainability issues. Minimizing energy demand of buildings by increasing building energy efficiency is the need of the hour due to the growth of population and high demand for fuel and electricity. 40% of total primary energy production of the world is consumed by buildings and they are responsible for producing 30% carbon dioxide emissions [1]. The building industry in Afghanistan consumes about 71% of total domestic electricity [2]
