Definition of a Net-Zero Energy Home A Net-Zero Energy Home (NZEH) is “capable of producing‚ at minimum‚ an annual output of renewable energy that is equal to the total amount of its annual consumed/purchased energy from energy utilities” and emits zero net carbon (1). This concept is becoming increasingly popular as people are becoming more aware of the effects of buildings on the environment. However‚ to build a net-zero home‚ in-depth design considerations to minimize “the energy requirements

To illustrate the principles described in the Systems Engineering Body of Knowledge (SEBoK) Parts 1-6‚ Part 7 is a collection of systems engineering (SE) implementation examples. These examples describe the application of SE practices‚ principles‚ and concepts in real settings. The intent is to provide typical instances of the application of SE so readers can learn from these experiences. This can improve the practice of SE by illustrating to students‚ educators‚ and practitioners the benefits

USING AQUARIUM WASTE WATER AS A NUTRIENT SOURCE FOR HYDROPONICALLY GROWN PLANTS January 2013 Abstract Have you ever noticed how cold water is in the morning and wondered if this can be somehow be used for air conditioning? The water in underground pipes stays cool because underground temperatures remain constant all year round regardless of what the outside air temperature may be. Conventional air conditioners are heat exchangers that take heat from a room‚ compress

as cardiovascular and microvascular could be reduced by improving glycemic control. In spite of the accessibility of therapeutic options such as self-monitoring of blood glucose‚ rapid-acting insulin analogues‚ planned patient education‚ and insulin pump therapy‚ glycemic control in the majority of patients with type one diabetes continues to be suboptimal. The major obstacle in strengthening the control is the increased risk of hypoglycemia. Nocturnal hypoglycemia was a common occurrence in 8.5% of

In this system a keypad is provided along with the microcontroller and syringe infusion pump. The anesthetist can set the level of anesthesia in terms of milliliters per hour to administer anesthesia to the patient with the help of keypad. After receiving the signal from the keypad‚ the microcontroller controls the signal to the desire level and fed into the stepper motor to drive the infusion pump in proper manner. The anesthesia is administered to the patient according to the stepper

Energy Efficient Building Windows Energy efficient windows have multiple layers of glass. The reason for this is because the more layers of glass you have the better it insulates the house. Three or four layers of glass are one of the best because you have more airspace in between layers. A smaller airspace doesn’t insulate the building as well as a thicker airspace would. The thickest an airspace should be is 1 inch because any thicker than that will cause the glass of the window

Energy Efficient Buildings Internal Heat Gains and Design Heating & Cooling Loads Internal Heat Gains People and electrical equipment in buildings give off heat. These internal heat gains must be included in energy balances on the building or zone to determine the net heating or cooling load. Heat Gain From People Typical sensible‚ latent and total heat rates given off by people are shown in the table below (ASHRAE Fundamentals‚ 2005). The sensible heat gain results from radiation and
