Climate changes are presenting the construction industry with many difficulties. Climate change challenges such as an increase in global average temperatures, the variability and frequency of severe weather conditions, and the availability of resources are affecting buildings and structures globally. Construction estimating companies and contractors are slowly waking up to the fact that the climate is already changing and that they have to come up with ways of mitigating future impacts. Indeed, this article seeks to highlight some of the approaches that the industry has adopted due to climate change.
Adopting Sustainable Building Designs
Modern construction estimation services companies have embraced sustainable construction/leed that focuses on energy efficient, and ecological building designs. Some of the passive housing principles such as; insulation, well-sealed building envelopes, efficient ventilation systems, and natural lighting and heat gain management. These methods help control indoor temperatures, more passively, without extensive use of heating and cooling appliances.
There is also an enhancement of architectural features like building orientation to allow the incorporation of natural lighting and air. The company also opts for more sustainable construction materials such as mass timber for construction and recycled steel in preference to emissions-intensive concrete. Many architects and contractors are incorporating a net-zero energy concept into newly constructed structures relying on onsite renewable electricity production.
Strengthening of structures and infrastructures for increased resistance to disasters
Given that extreme climate change is attributed to floods, hurricanes, and wildfires, new constructions and structures should be able to mitigate such disasters. This reveals that the evaluation of site-specific climate risk helps identify key risks and necessary resilience mechanisms for developers. Some of the measures that can be taken include increasing the minimum heights, making some critical systems sealed, and having backup mechanisms in place.
Another factor that is also being recommended is thermal factors, this includes insulation of façade, planting of trees, and introduction of innovations such as green roofs. Other structures are also being adapted to and modified to accommodate the estimated climate changes in a certain area.
Managing Water Resources Responsibly
Given the increased incidences of drought owing to climate change, it is paramount to ensure proper management of water in construction. Measures like rainwater harvesting, low-flow plumbing fixtures, recycled water, and the use of xeriscape are some of the practices that have been adopted to conserve water. Yet again, permeable pavements are even better in allowing groundwater recharge.
They are useful plans that make buildings more autonomic and help alleviate demand for local water sources during periods of drought. Other localized measures include flood barriers, bioswales, retention ponds, and urban stormwater capture systems as part of measures that can be used to address the impacts of heavy rainfall.
Embracing Circular Construction Practices
The circular economy is emerging as a new way of life and is slowly being adopted by the construction industry. This encourages closed-loop material flow as it recycles the resources and brings about reduced wastage. Demolition and recycling of building materials helps in retaining the energy that is previously put in them, has a reduced carbon emission level than if new products had been used, and reduces the amount of waste that is dumped in the landfill. The principles of design for deconstruction also assist in future reuse.
A construction estimating service or, even better, a demolition waste management service can help you figure out the allowed the reuse of recycled aggregates, metals, wood, etc in the creation of new construction. Offsite modular and pre-fabrication methods also reduced the wastage of materials at the construction site. In general, the circular construction model can be said to be compatible with decarbonization processes taking place worldwide.
Leveraging Technological Innovations
Some of the new age technologies that are being applied in the construction of climate adaptation are energy modeling software that computes the efficiency of building designs, drone survey that helps in attaining high-resolution data to measure risks of climate change, 3D printing that uses less material and energy than traditional building techniques, self-healing concrete that enhances the ability of structures to endure stresses that are brought about by climate change, and real-time performance monitoring through the use of Internet of An example of this is building information modeling, which is a visual representation of architecture, engineering, and construction data in assessing the overall impacts of the total life cycle.
Big data, analytics, AI, and digital twins are also being embraced to predict risks, asset degradation, or service requirements accurately. These technologies improve accuracy, responsibility, and preparedness for climate change.
Adopting Renewable Energy Sources
To lead the building sector towards a sustainable future and meet the goal of net zero emissions, constructions will need to shift from fossil fuel-based energy sources. Small-scale solar panels, windmills, geothermal drills, and bioenergy plants can provide heating, cooling, lighting, and even operational energy within localities. Unused clean power can also be sold back to the grid or self-consumed by the building or compound they were installed in.
Onsite renewable integration minimizes dependence on centralized carbon-intensive utilities and increases efficiency and self-reliance – key resilience elements. renewable installations may be comparatively expensive at the installation stage but can be self-funding from year to year through reduced energy costs. It may also involve various financing models such as PPPs, green bonds, and sustainability-linked loans to mobilize funds.
Conclusion
Climate change is a clear threat to the construction sector since it has several effects on construction-related structures. Fortunately, the level of awareness and activity related to adaptation is increasing in the industry at a global scale. As explained earlier, several urgent enterprise-wide changes are being adopted by leading construction estimating services firms, including; constructing net-zero buildings, improving resistant infrastructure, managing material consumption, adopting new technologies, and transitioning to renewable energy.
Financial innovation is also defying the transition barriers: As difficult as the way forward is, those proactive stances throughout the planning, design, engineering, and project delivery life cycles are positive moves towards climate-proofing the built environment. Construction companies are learning how to build back better to get to a low-carbon and climate-resilient world in the wake of each disaster.
