A Comprehensive Examination of Building Life Cycle Stages: From Construction to Operation

Published by firstgreen on

Navigating the intricate stages of a building’s life cycle requires meticulous planning, data collection, and precise execution. Firstgreen Consulting, an industry leader in renewable energy consulting, delves into the nuances of this process, from the construction stage to the operation phase. By harnessing our expertise in solar, wind, and energy storage technologies, we present a detailed analysis that aligns with global standards, ensuring sustainable construction and operation.

The Construction Stage: An Overview

Module A4: Transportation and Logistics

At the heart of the construction stage lies Module A4, focusing primarily on the transportation of materials. It encapsulates the journey of materials from the manufacturing unit’s gate to the construction site. Determining accurate distances for each material is crucial, factoring in their production location vis-a-vis the building’s site.

Should precise distance estimation be unattainable, average distances can be employed as a reference. Furthermore, the choice of transportation mode varies depending on whether the materials are sourced locally or imported.

Module A5: On-Site Activities and Energy Consumption

Module A5 offers a panoramic view of the myriad activities occurring on-site during the building’s construction. From initial groundwork and equipment usage to on-site transportation and waste management, every detail is encapsulated. It’s imperative to account for emissions resulting from combustion engines during this phase.

Research indicates a glaring dearth of comprehensive studies focusing on this life cycle stage, rendering precise value quantification challenging. For instance, according to a study by Sjunnesson, electricity consumption during house construction ranges from 0.5 to 3.3 kWh per gross floor area. Meanwhile, in the case of office buildings, the electricity demand can be as low as 0.1% of the total requirement.

In scenarios lacking concrete data, rough estimates dictate an energy consumption range of 1-5 kWh/GFA for residential structures, 5-20 kWh/GFA for multi-storey residences, and 20-80 kWh/GFA for office buildings.

Transitioning to the Operation Stage

Modules B1-B5: Maintenance, Repair, and Refurbishment

Transitioning to the operation stage, Modules B1-B5 encompass essential data regarding the upkeep, repair, and refurbishment of the building’s structural system. These modules, aligned with the estimated service life of the structural components, shed light on long-term sustainability.

Special features designed to boost a building’s adaptability to evolving functional requirements further necessitate comprehensive scenarios. Such features might extend the analysis’s time frame, ensuring the building remains viable and functional in the long run.


Sustainable construction and operation are no longer mere buzzwords; they’re an imperative in today’s environmentally-conscious era. By dissecting and understanding each phase of the building’s life cycle, we can make informed decisions, promoting energy efficiency and sustainability. At Firstgreen Consulting, our commitment lies in propelling businesses towards greener horizons, ensuring a sustainable and prosperous future for all.
