Green Roof System Analysis

a sustainable building maximizes daylighting, has a good ventilation and moisture control.It also optimizes acoustic performance. 6. Optimize Operational and Maintenance Practices Designers can specify materials and systems that simplify and reduce maintenance requirements; require less water, energy, and toxic chemicals / cleaners to maintain; and are cost-effective and reduce life-cycle costs. Energy conservation in building is very important and best way to decrease the energy consumption is using solar energy and creating passive building design.Buildings with passive solar building designs use the sun’s energy for free heating, cooling and daylighting. This decreases energy consumption and gives a comfortable environment inside.

Did you know you can turn you spoil in to rich soil by composting? As Mississippi University of Mississippi said “the best way to have rich and fertilized soil is to compost”. Well you might be thinking how can food waste turn into rich soil? Since the food waste has nutrients in it the soil absorbs it which will turn it into rich fertilized soil. Another benefit of composting is that it can reduce the amount of times you need to water your plants.

For plant survival, not only the plants need water and sunlight to grow and be healthy, they also need heat. If a farmer wants to plant earlier or later in the growing season, he or she will have to use greenhouses to keep heat from escaping and making a suitable climate for plant survival (Maggio, 2017). Heat can be used in producing energy and for safety. Solar energy makes use of heat by trapping it and converting it to energy that a household or a community can use (Maggio, 2017). For safety, heat is used to cook food and with this help, the microorganisms that can cause illnesses will decrease or diminish and the person can eat it safely (Maggio, 2017).

The single effect thermal vapor compression seawater desalination process is illustrated schematically in Fig. 2. This process uses low-temperature heat source such as waste heat from an industrial process or solar energy to generate fresh water. This system has two distinct advantages: First, it can utilize the low-temperature heat source in the range of 50 °C to 80 °C, which leads to lower grade energy is used. Second, seawater doesn’t need to be heated to a high temperature, which saves energy and reduces scale.

The substance undergoes a process called supercritical drying where the liquid is removed from the gel leaving the linked silica network without causing the material to collapse. As aerogel is made up of 95% to 99% air, it is very porous. Its pores are exceptionally minuscule preventing air particles from colliding with another and stopping gas phase conduction, and with that heat energy loss. To increase aerogel insulations effectiveness more materials are added, such as carbon. Aerogel insulation significantly reduces convection, conduction and radiation, which are the three procedures of heat transfer ("Low Energy House - What is Aerogel Insulation?").

It provides extra nutrients for the plant’s growth and life cycle. It can also increase the soil’s capability to retain water. Organic farms use humus since it is composed of decomposing leaves, another chemical reaction. Humus, which is essential to the soil, balances out the presence of carbon and nitrogen ratio of the soil. It can also retain, remove or lower concentrations of pollutants present in the soil (Royal Society of Chemistry,

There are mostly two kinds of Roofing these days. First is the Commercial and other one is the Residential Roofing. Commercial Roofing is used to ensure and seal the highest point of commercial structures while residential roofing is for the security of the private houses and flats. It covers basic entries and avoids leakage of rain water from entering the building. Commercial Roofing by and large has a generally level slant, instead of Residential Roofing, which is regularly steeply inclined.

The organic agriculture techniques are known as ecological sustainable by • Improving soil structure and fertility through the use of crop rotations, organic manure, mulches and the use of fodder legumes for adding nitrogen to the soil fertility cycle. • Prevention of soil erosion and compaction by protecting the soil planting mixed and relay crops. •

Many people argue whether an natural fertilizer or an chemical fertilizer helps plant growth. There are many differences between the two fertilizers as far as how much nutrients are found in it and the long term effect of the plants. The question is how do gardeners decided which fertilizer will benefit their plants the most? There are many advantages to using a more natural fertilizer. This fertilizer has a more long term effect, the fertilizer improves the structure of the soil which makes it easier to hold water and the nutrients it needs to be a long lasting plant(A comparison between).

Using sufficient amount of lime (to provide enough alkalinity), compaction of the soil to high density and prompt placement after mixing lime with soil (to minimize carbon dioxide penetration) can minimize potential carbonation problems. In a lime treated soil, if sulfates are present in the soil or water, then these sulfates may react with alumina released from clay and calcium from lime to form ettringite (Ca6[Al(OH)6]2. (SO4)3.26H2O) (Mohamed, 2000). Ettringite has the capability of imbibing large volumes of water and dramatically increases the swelling potential of the lime-stabilized soil. It would be prudent to test and understand whether lime, soil, and sulfate swell or not when mixed and exposed to moisture, if sulfates are present where lime stabilization is
