Smart metering is the initial point for the conversion of traditional building structure to a smart building structure. This smart meter deployed in the smart buildings need to automatically monitor, control, interact, and optimize energies. Another important step is designing a smart lighting system that has sensors, controllers, drivers, communication, and logic systems. This smart metering and lighting systems can turn the conventional buildings to smart buildings that can provide a smart world with 100% renewable energies. Carbon footprint can be reduced with the help of renewable energy sources. The automatic systems can provide an optimized solution with the proper data usage and efficiently use the renewable sources [65].
Green Audit: A Step Towards Sustainable Environment
Published in Kailas L. Wasewar, Sumita Neti Rao, Sustainable Engineering, Energy, and the Environment, 2022
Carbon footprint is the total amount of greenhouse gases (GHGs) emitted by way of vehicles, generator sets in terms by a person, institute, company, state, or country. For calculation of carbon footprint, the basic data regarding direct and indirect sources of emission of GHGs is required. The GHG are calculated using the values of emission factors, like use of electricity, use of diesel generators for electricity generation or any other purpose, LPG consumption, food wasted and vehicular emission [3].

The carbon footprint is a climate change indicator, similar to measuring GHG emissions and removals associated with a particular process or product. A carbon footprint of a product is the sum of direct and indirect GHG emissions generated throughout its life cycle. The measurement of GHG emissions is done in terms of CO2 equivalents, calculated for a given time horizon, normally 100 years.
Environmental sustainability in construction: Influence of Megaterium Bacteria on the durability and mechanical properties of concrete incorporating calcined clay

Environmental sustainability has become a critical issue in the construction industry as it is one of the most resource-intensive and polluting sectors. Traditional building materials such as cement and concrete have a significant environmental impact, contributing to greenhouse gas emissions and depletion of natural resources. Therefore, there is an urgent need for sustainable building materials that are environmentally friendly and reduce the carbon footprint of construction. One promising solution is the use of bacterial concrete, also known as bio cement, which is a novel building material that utilizes the metabolic activities of bacteria to enhance the properties of concrete [1]. One of the most commonly used bacteria in the production of bacterial concrete is Bacillus megaterium, which is known for its ability to produce calcite, a mineral that can enhance the strength and durability of concrete.
My Experience with IABSE and a reflection on the challenges we will face in the near future
Published in Structural Engineering International, 2023
The second reflection is the consideration of climate change. On the mitigation side, how can we reduce the carbon footprint of our constructions with innovative concepts, methods and materials? How to think in terms of reusing and transforming structures rather than demolition/reconstruction? Regarding the adaptation to climate change, we investigated in IABSE TG6.1, how to quantify the short, medium and long-term impact on structures. We had the chance to merge the knowledge of several members working in different locations in the world on the effects of climate change on structures. A next step in future years that is essential for structure owners will be to help them translate the trajectories among the various forecast climate scenarios as well as a time horizon into an adaptation strategy for structures. One key aspect is to include the effects of climate change in the assessment of structural vulnerability within life-cycle reliability and risk-based evaluations.
The Carbon Footprint of Bridges
Published in Structural Engineering International, 2022
The bridges vary from 2 m wide footbridges to 50 m wide highways. To avoid the influence of the varying width, the bridges’ carbon data are plotted against the deck area in Fig. 6; the scatter of the data is reduced. There is a significant range of carbon values with a trend for increased carbon with increased area. The size of the bridges varies considerably from 50 to 135,000 m2. The largest 10 bridges account for almost 50% of the total aggregated deck area and 75% of the carbon in the database. A couple of the highway bridges in Fig. 6 are outliers in the general data. The data point below the general data (1) is for a refurbishment project rather than a new bridge. Collings1,2 noted that, for both buildings and infrastructure, refurbishment of existing assets tends to give a lower carbon footprint than building new. There are insufficient data on refurbishment in this dataset to gain further insight on this. The data point above the general data (2) is for an 18 m span bridge cutting through a hill and has significant embedded retaining walls associated with it. It has been previously noted1,2 that both buildings and infrastructure with significant underground structure and foundations tend to give a high carbon footprint.
