Impact Of Climate Change To The Environment – One of the main reasons for global warming is the continued increase in CO2 emissions, which trap heat and warm the atmosphere. With more frequent storms, landslides or floods, buildings are becoming more vulnerable to climate change and their lifespan is shortened. Since energy plays a key role in the management of buildings, in this article we will discuss the consequences of climate change and increased CO2 emissions on the building’s energy consumption and the comfort of its occupants. For the following calculations, we use Building Energy Modeling (BEM) to evaluate how an office building will behave in the near (2050) and distant future (2100) compared to the year it was designed (2000).

As you may know, Dexma uses BEM for many purposes, such as simulating the impact of energy efficiency retrofits, estimating the breakdown of energy consumption, or assessing the impact of different scenarios.

Impact Of Climate Change To The Environment

To illustrate the impact of climate change on buildings, we focus on the following key weather parameters for the built environment:

Climate Change And Health Care

The influence of other meteorological parameters such as wind speed, solar radiation or precipitation has been neglected, either due to a lack of literature or due to their estimated small impact on building behavior.

Atmospheric CO2 concentration is expressed in Parts Per Million (PPM) and has fluctuated between 200 and 300 ppm over the past few centuries.

Based on the baseline projections of the OECD Environmental Outlook, the current atmospheric CO2 concentration has been around 400 ppm since the 2000s, reaching a new limit. Atmospheric CO2 concentration is expected to continue increasing, reaching 530 ppm by 2050 and 780 ppm by 2100.

If we want these alarming numbers to fall, we have no choice but to significantly reduce our emissions. Unfortunately, even if we were to stabilize our CO2 emissions, this would not be noticeable immediately. In fact, it takes time for the emitted CO2 to be naturally removed from the atmosphere: while some cycles are rapid and can eliminate CO2 in 5 years, the absorption of CO2 by the soil, oceans or vegetation can take thousands of years…

Climate Change And The Butterfly Effect

Outdoor air temperature or dry bulb temperature is basically what we are referring to when we talk about air temperature. It is called a “dry bulb” because the air temperature is displayed by a thermometer that is not affected by humidity.

Based on the same OECD forecasts, the outdoor air temperature will increase by 土 2 °C by 2050 and by 土 4 °C by 2100 compared to 2000.

This change in temperature affects us all. It leads to regional and seasonal temperature extremes, while reducing snow cover and sea ice, increasing heavy precipitation, and changing the diversity of plant and animal habitats – some becoming larger, others smaller.

“Earth’s temperature has increased by 0.08° Celsius (0.14° Fahrenheit) per decade since 1880, but the rate of warming since 1981 is more than double that: 0.18° C (0.32° F) per decade decade,” as highlighted in this climate .gov report.

Potential Climate Changes Impact

Relative humidity (RH) is a measure of how much water vapor is in a water-air mixture compared to the maximum possible amount. It is expressed as a percentage from 0% (completely dry air, zero moisture content) to 100% (air saturated with moisture, additional moisture condenses). There are fewer studies on the connection between outdoor humidity and climate change, but PNAS’s study indicates a decline in relative humidity of 0.2% per decade over the past 50 years (illustrated by Graph C).

Combined with rising outside air temperature (Graph A), total humidity (specific humidity) actually increases, as Graph B shows. A study shows that this deadly combination of increasing heat and humidity could have many direct health consequences. can affect productivity and even lead to death, even in healthy people.

The resulting weather conditions can be summarized in the following psychrometric chart (more information on psychrometric charts can be found here) and show the higher dry bulb temperatures and humidity conditions.

Now let’s imagine an office building in Lyon, France, a temperate region of Europe, built in the 2000s. We assume a 3-story building with a heat pump for heating and a chiller for cooling, with a building envelope that meets year 2000 standards. Thanks to Dexma’s BEM tool, you can estimate the impact climate change on the building thanks to different indicators (IAQ, thermal comfort, indoor air temperature and humidity, HVAC energy consumption) and for three different climate scenarios that we have mentioned: the years 2000, 2050 and 2100.

It affects the physical environment and all aspects of both natural and human systems – including social and economic conditions and the functioning of health systems. It therefore represents a threat multiplier that undermines and potentially reverses decades of health progress. As climatic conditions change, more frequent and intensifying weather and climate events are observed, including storms, extreme heat, floods, droughts and wildfires. These weather and climate hazards have both direct and indirect impacts on health, increasing the risk of death, noncommunicable diseases, the emergence and spread of infectious diseases, and health emergencies.

Climate change is also impacting our health workforce and infrastructure, reducing the ability to provide universal health coverage (UHC). More fundamentally, climate shocks and growing stresses such as changing temperature and precipitation patterns, droughts, floods and sea level rise are affecting the environmental and social determinants of physical and mental health. All aspects of health are affected by climate change, from clean air, water and soil to food systems and livelihoods. Further delay in addressing climate change will increase health risks, undermine decades of improvements in global health, and contradict our shared commitments to ensuring the human right to health for all.

The Intergovernmental Panel on Climate Change’s (IPCC) Sixth Assessment Report (AR6) concluded that climate risks are occurring faster and becoming more severe than previously expected, and that adapting will be more difficult as global warming increases.

Animals That Are Feeling The Impacts Of Climate Change

It also shows that 3.6 billion people already live in areas that are particularly vulnerable to climate change. Although low-income countries and small island developing States (SIDS) contribute minimally to global emissions, they suffer the most serious health impacts. In vulnerable regions, the death rate from extreme weather events has been 15 times higher in the last decade than in less vulnerable regions.

Climate change impacts health in a variety of ways, including causing deaths and illnesses due to increasing frequency of extreme weather events such as heat waves, storms and floods, disruption of food systems, increases in zoonotic diseases, and food, water and and vectors leads to communicable diseases and mental health problems. Furthermore, climate change is undermining many of the social determinants of good health, such as: B. Livelihoods, equality and access to health care and social support structures. These climate-related health risks are disproportionately felt by the most vulnerable and disadvantaged, including women, children, ethnic minorities, poor communities, migrants or displaced people, older populations and people with underlying health conditions.

Although it is clear that climate change is having an impact on human health, it remains a challenge to accurately assess the extent and impact of many climate-related health risks. However, scientific advances are increasingly allowing us to attribute increases in morbidity and mortality to global warming and to more accurately determine the risks and extent of these health threats.

Data shows that 2 billion people lack safe drinking water and 600 million suffer from food-borne illnesses annually, with children under 5 years old causing 30% of food-related deaths. Climate stressors increase the risk of water- and food-borne diseases. In 2020, 770 million people were affected by hunger, mostly in Africa and Asia. Climate change is affecting the availability, quality and diversity of food and exacerbating food and nutrition crises.

Changes in temperature and precipitation increase the spread of vector-borne diseases. Without preventative measures, the number of deaths caused by such diseases, which currently exceeds 700,000 annually, could increase. Climate change causes both immediate mental health problems such as anxiety and post-traumatic stress, as well as long-term disruptions due to factors such as displacement and disrupted social cohesion.

Recent research attributes 37% of heat-related deaths to human-caused climate change. Heat-related deaths among people over 65 have increased by 70% in two decades. In 2020, 98 million more experienced food
