10 Easy-to-Make Home Designs That Promote Sustainability



In a world where the environment becomes the capitalist of all human trade, a century-old debate continues to heat up – sustainability. Most of the resources we use at home are finite, and if we keep on using them; the future generations will have nothing left. That is why it is necessary for us to tap the other resources that nature provides in infinite amounts. Below are the 10 easy designs that you can use to gear your home toward sustainability. You do not just save energy but conserve energy in style.
1. Sustainable Landscaping
The quest for sustainability starts in our very home landscape. The easiest approach would be creating a compost pit to nourish our soil. Once the soil becomes healthy, we can start making vegetable patches where we can plant, grow, and harvest, fruits and vegetables of our own. Adding more trees will keep your home cool during the summer and will add more aesthetic value to our house is also a great plus.
2. Use Reclaimed Bricks
Bricks don’t just shrivel up and vanish. Most of them can last for decades and even centuries. So why use new ones if we can just gather old bricks from old homes and from already-demolished ones? Yes, there are old bricks gathered around town, and we can always have our local contractor piece the reclaimed bricks together to form house walls and apply artistic finish on its ancient surface.
3. Use Reclaimed Lumber
Trees that were uprooted and destroyed by storms and other natural disasters can still be treated and processed into a usable wood that can be applied to various home improvement projects. Wood from old chairs and other fixtures can also be reclaimed and refinished for newer purposes. That way, we can prevent the need for newer lumber, which also decreases our contributions in cutting trees down.
4. Employ Passive Design Approach to Cool or Warm Homes
Using a passive design approach in houses can significantly decrease the energy consumption for heating. It uses passive solar air to warm the entire house. According to various studies, buildings that use such design approach can mitigate their own energy consumption for a whopping 90 percent.
5. Build a Solar Water Heater
Building a solar-powered water heater of our own is one of the best things that anyone can do for sustainable living. It helps cut down energy costs, as it only relies on passive solar heat to keep water hot and well-insulated.
6. Use Low Flush Toilets
Unlike their ancient counterparts, the modern low flush toilets can save approximately four and a half gallons of water. This effectively saves a lot of money when it comes to water bills, and as far as I am concerned, saving money will always be something that I should do, on any circumstances!
7. Build a Rainwater Harvester
Rainwater can be used for bathing, cooking, and drinking. That is why it is important to save water by gathering rainwater for future use. Not only that it’s safe, it’s also free! Rainwater is also free from the contaminants that ground and surface water are always exposed to, and according to the Texas Water Development Board, rainwater can even exceed ground and surface water in terms of safety and quality.
8. Install Faucet Aerators
Faucet aerators add air to your faucet, thereby breaking the flow of water and turning it into droplets. This ingenious way of dispersing water allows to cover more surface area, which saves a considerable amount of water in any home. If you don’t believe me, even the U.S. Environmental Protection Agency contends that installing faucet aerators is one of the best ways you can do to help conserve water.
9. Use a Higher Ceiling and awnings to improve ventilation
Hot air stays up. That is why it is necessary to keep our ceiling high so they can stay there during hot days. A window installed in the higher ceiling area will allow hot air to escape. Installing an awning can be beneficial too for giving protection both for rain and too much sunlight. Such design will enable the free flow of air, which will decrease the need for relying in air conditioners. Ergo, lesser electric bills!
10. Use Greywater Storage Tanks
Greywater is what remains after potable water has been used for washing purposes. Though generally dirty, it can still be used to flush toilets and nourish the topsoil. Relying on greywater can also help reduce the need to extract more freshwater, which ultimately saves clean drinking water.
In this day and age, it is necessary for us to be aware of the things we could do to help make a difference. Remember, if everyone does their part, our collective efforts will accumulate to become a world-changing one.

How Hot Was It Long Ago?


The question seems simple enough: What happens to the Earth’s temperature when atmospheric carbon dioxide levels increase? It has happened in the past. The answer is elusive. However, clues are hidden in the fossil record. A new study by researchers from Syracuse and Yale universities provides a much clearer picture of the Earth’s temperature approximately 50 million years ago when CO2 concentrations were higher than today. The results may shed light on what to expect in the future if CO2 levels keep rising. The study which for the first time compared multiple geochemical and temperature proxies to determine mean annual and seasonal temperatures, is published online in the journal Geology, the premier publication of the Geological Society of America, and will be published in print on August 1.

SU Alumnus Caitlin Keating-Bitonti is the corresponding author of the study. She conducted the research as an undergraduate student under the guidance of Linda Ivany, associate professor of earth sciences, and Scott Samson, professor of earth sciences, both in Syracuse University’s College of Arts and Sciences. Early results led the team to bring in Hagit Affek, assistant professor of geology and geophysics at Yale University, and Yale Ph.D. candidate Peter Douglas for collaborative study.


The Eocene epoch, lasting from about 56 to 34 million years ago, is a major division of the geologic timescale and the second epoch of the Paleogene Period in the Cenozoic Era. The Eocene spans the time from the end of the Palaeocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by the emergence of the first modern mammals. The end is set at a major extinction event called Grande Coupure (the "Great Break" ), which may be related to the impact of one or more large bolides in Siberia and in what is now Chesapeake Bay.

The temperature gradient from equator to pole was only half that of today's, and deep ocean currents were exceptionally warm. The polar regions were much warmer than today, perhaps as mild as the modern-day Pacific Northwest; temperate forests extended right to the poles, while rainy tropical climates extended as far north as 45°. The difference was greatest in the temperate latitudes; the climate in the tropics however, was probably similar to today's. The recent discovery of a giant snake in Colombia that may have lived during the Eocene suggests, on the contrary, that the tropics were much warmer than today, a conclusion in accord with numerical simulations of the climate during the Eocene.

Earth's surface temperatures generally rose from the late Palaeocene through the Early Eocene, reaching maximum Cenozoic temperatures during the Early Eocene Climatic Optimum. Superimposed on this warming were a series of "hyperthermals". These are best described as geologically brief (<200 kiloyears) events characterized by rapid warming global warming and massive carbon input to the ocean and atmosphere. The most prominent of these events was the Palaeocene-Eocene Thermal Maximum or Initial Eocene Thermal Maximum (PETM), which began at the Palaeocene-Eocene Boundary. During this episode. Earth surface temperatures rose by 5-7 °C. The PETM coincided with a major mammalian turnover on, and an extinction of many species in the deep sea.

Previous studies have suggested that the polar regions (high-latitude areas) during the Eocene were very hot—greater than 30 degrees centigrade (86 degrees Fahrenheit). However, because the sun’s rays are strongest at the Earth’s equator, tropical and subtropical areas (lower latitude) will always be at least as warm as polar areas, if not hotter. Until now, temperature data for subtropical regions were limited.

The SU and Yale research team found that average Eocene water temperature along the subtropical U.S. Gulf Coast hovered around 27 degrees centigrade (80 degrees Fahrenheit), slightly cooler than earlier studies predicted. Modern temperatures in the study area average 75 degrees Fahrenheit. Additionally, the scientists discovered that, during the Eocene, temperatures in the study area did not change more than 3 to 5 degrees centigrade across seasons, whereas today, the area’s seasonal temperatures fluctuate by 12 degrees centigrade. The new results indicate that the polar and sub-polar regions, while still very warm, could not have been quite as hot as previously suggested.

The findings are based on a chemical analysis of the growth rings of the shells of fossilized bivalve mollusks and on the organic materials trapped in the sediment packed inside the shells, which was conducted by Keating-Bitonti and her colleagues. Ivany collected the fossils from sediment layers exposed along the Tombigbee River in Alabama. The mollusks lived in a near-shore marine environment during a time when the sea level was higher and the ocean flooded much of southern Alabama. The sediments that accumulated there contain one of the richest and best-preserved fossil records in the country.

"Our study shows that previous estimates of temperatures during the early Eocene were likely overestimated, especially at higher latitudes near the poles," Keating-Bitonti says. "The study does not mean elevated atmospheric CO2 levels did not produce a greenhouse effect; the Earth was clearly hotter during the early Eocene. Our results support predictions that increasing levels of atmospheric CO2 will result in a warmer climate with less seasonality across the globe."
