For basements, insulation is done on the exterior walls. The basement is usually more connected to the other living spaces than even the outside environment which makes basement insulation even prefferd to ceiling insulation. For new homes insulation for the exterior basement walls includes reducing heat loss through the foundation and thermal bridging. Backfilling is also done to prevent damage to damp-proof. Thermal bridging is a very effective ad is doe as shown in the figure
It will be difficult for a person to express discomfort who is not familiar with thermal comfort. Satisfaction may be expressed but dissatisfaction is not state of mind. Psychological aspects are important factors for both indoors and outdoors. A simple experiment done by Rohles discourse how mere changes in the furniture finish by adding wood-panels and comfortable pattern can make occupants feel warmer by telling them that the temperature is warmer than the previous set up. (Rohles, February 2007) The thermophysical definition of comfort is based on the characteristics of thermal receptors in the skin and hypothalamus.
Energy efficiency or efficient use of energy is a term which is used in the practice of saving or making efficient use of energy. Energy efficiency can be achieved through variety of ways and means in order to save energy. The results of energy efficiency can be greatly positive and having good impacts not only upon energy consumption but also upon overall environment. With regards to energy efficiency, there have been invented a number of appliances such as; LED lights (lengthened as Light emitting diode), natural skylights, fluorescent lights and there are also other systems (Cagno, 2013). Modern technology has been designed in a way to promote energy efficiency and not only that there are a number of other benefits of energy efficiency.
Furthermore, SFI is an extremely versatile insulation technology applicable anywhere, such as in residential homes, commercial or industrial buildings. Due to the fact that it takes less space and its thickness level can be conveniently altered to suit the target purpose, SFI is commonly installed in places like: Garage—SFI around garages doors and walls prevents bugs while helping to maintain warmth during fall and
Daylight is a source which can save the energy use and it is able to create a pleasant environment and a sound visual comfort for building occupants. A good day-lighting strategy is necessary in order to decrease energy consumption of artificial lighting. To provide effective internal illumination, the placing of the right openings in the right positions with suitable type of window and glazing is important. The type of glazing and window has major significance on the performance of daylight and thermal performance in buildings. By having a good day-lighting approach, one can have a visually sound and productive environment for building occupants.
In the first place, we can improve our house by using convenient devices such as energy-efficient lights, solar water heater or portable air compressor. The portable air compressor can supply air for our house’s heating, ventilation and air conditioning system or a best portable air compressor could do more than that. It may such as fulfill the gas cylinder, give air for tire filling. Researches point out that using energy-saving appliances could save
Compliance to ethical & environmental standards & OSHA and working conditions also form a part of social sustainability. BENEFITS Apart from the benefits of economic & environmental the benefits which sustainability offers to it various associated sectors are as follows: COST & VALUE: Buildings incorporating sustainable practices offer high performance providing best value to the occupants through life cycle cost benefits. Considering the high initial costs, the benefits which it offers through its positive effects on human health and running costs offset the initial capital costs involved. Overall improvement in the buildings performance and efficiency thus reducing costs. Not only do we benefit from the cost perspective but also gain on the societal benefits through enhanced quality of life for building occupants thus increasing the value content.
Building Envelope plays a key role in determining the required energy for cooling, heating, and lighting of buildings. Proper building envelope design can strongly save energy and enhance indoor environment and occupants’ comfort. Energy modeling is a very powerful tool to simulate energy behavior in the buildings and the effect of the building design in the energy interaction with the surrounding. This allows designers to make alterations to the building design or operation while simultaneously monitoring the impact on system behavior and performance. Energy modeling of building envelope in residential buildings form architectural and structural perspectives can increase the energy efficiency of these buildings and reduce the
In addition to these, many production processes include heat transfer in various forms: it might be the cooling of machine tools, pasteurization etc. In most of these applications, heat transfer is improved through some heat transfer devices such as heat exchangers, evaporators, condensers and heat sinks. Increasing the heat transfer efficiency of these devices is suitable, because by increasing efficiency, the space occupied by these devices can be minimized, which is an important for applications with compactness requirements. Further, in most of the heat transfer systems, the working fluid is circulated by a pump, and improvements in heat transfer efficiency can minimize the associated power
As shown in Figure 2-2, when the air becomes warm and moist, it naturally rises up in the cooler, and as a result, outside air being drawn in. To generate the necessary airflow, natural draft cooling towers require tall stacks to create the required draft. Figure 2-2: Natural draft cooling
