Carbon Accounting and Retrofit in Architectural Planning

Carbon Accounting and Retrofit in Architectural Planning

Climate change is one of the most acute global problems of our time. Anthropogenic emissions of greenhouse gases, primarily CO2, lead to an increase in the planet's temperature with all the ensuing negative consequences. The construction sector is one of the largest sources of CO2 emissions, accounting for about 40% of global carbon dioxide emissions.

In this context, reducing the carbon footprint in architecture and construction becomes of paramount importance. A comprehensive approach is necessary - from carbon accounting and energy-efficient design to retrofitting existing buildings. Architects are called to play a key role in creating an ecological and sustainable living environment.

Carbon Footprint in Architecture

The construction and operation of buildings are among the main sources of greenhouse gas emissions. Experts estimate that buildings account for about 40% of global CO2 emissions. The carbon footprint of a building is the amount of greenhouse gas emissions throughout its entire life cycle: from the extraction of building materials to demolition.

To reduce the carbon footprint, architects pay attention to the selection of eco-friendly materials, energy efficiency of buildings, and renewable energy sources. The design stage plays a key role. It is at this stage that decisions are made that affect future CO2 emissions.

Retrofitting Existing Buildings

In addition to designing new buildings, it is important to reduce the carbon footprint of existing ones. This is achieved through retrofitting - a set of measures for modernizing and increasing the energy efficiency of existing buildings.

During retrofitting, solar panels and wind turbines can be installed, facades insulated, windows and doors replaced, and engineering systems modernized. Such measures can reduce energy consumption for heating, ventilation, and lighting by 30-50% or more. This significantly reduces the building's carbon footprint.

Carbon-Neutral Design

Modern technologies allow for the creation of carbon-neutral buildings, whose CO2 emissions are fully offset by renewable energy sources. This is achieved through a set of solutions.

Firstly, maximum use of natural lighting, natural ventilation, insulation, and smart systems for energy saving. Secondly, the use of eco-friendly and local building materials. Thirdly, complete autonomy through solar panels, wind turbines, and heat pumps.

Such buildings not only reduce their own CO2 emissions to zero but also generate surplus clean energy for other needs. This is the future of sustainable architecture.


The carbon footprint of buildings is a crucial factor in the context of climate change. A comprehensive approach that includes carbon accounting, retrofitting existing buildings, and designing carbon-neutral buildings can significantly reduce CO2 emissions in the construction sector. Architects play a key role in creating an ecological and sustainable living environment.
