-Introduction
In this essay, I will discuss the features, price savings and advantages of Loft insulation. In cold climates, Loft insulation plays the simplistic and essential role of keeping the warmth in a house from the cold air outside. It is used in almost every house, building, skyscraper and store to maintain a constant temperature! In fact, over 40% of heat escapes through the loft, so it is very important to insulate it. This will prevent cold air from disturbing your warmth.
-Science Involved
Keeping a stable room temperature is the purpose of Loft insulation. It is a fairly simple method of insulating, but is very effective. The air cells in loft insulation is a very bad conductor, but a good insulator. When Winter comes around the corner, people crank up their heaters. The warm air rises to the ceiling and loft insulation blocks the heat from escaping. It is the same when Summer arrives. It also keeps warm from coming inside your house by blocking its passage.
-Advantages
There are different types of Loft insulation that are used for different purposes. For instance, using Natural Sheep’s Wool is a good choice as it’s naturally fire retardant and produces no toxic gasses. Also, if bought correctly includes rat repellent. The next type of Loft Insulation is Dry Cellulose. Dry Cellulose is essentially recycled paper that has a mineral salt fire retardant and mold preventor sprayed on it. The most popular and efficient solution is Fiberglass insulation. It is fire retardant by nature. Fiberglass is easy to install and relatively inexpensive. In general, Loft insulation can save you up to £200 and 230kg of CO² per year!
-Disadvantages
Loft insulation has a very small amount of disadvantages. One main disadvan...

In this paper over natural refrigerant I will be covering the pros and cons of natural refrigerant in light commercial and residential applications. There are many natural substances in this world that can be used to help or decrease the efficiency of a heating ventilation air conditioning system. Some of these substances are water, air, ammonia, and hydrocarbons. All these substances are natural that come from the earth we live on. Over the course of this paper I will be covering the pros and cons of swamp coolers, geo thermal heating and cooling units and how these natural substances can help and or decrease how your heating and cooling unit performs.
... the sun isn’t as high up in the sky. Large open spaces and a covered loft promote stack ventilation which also further increase the comfort zone. A mud room/hallway doubles as an airlock during extreme temperature months. The addition of active systems suffices for the rest of the heating load. On the roof positioned is a solar hot water panel which has access to solar gain. A small tankless electric water heater boosts stored hot water temperatures when needed. The ultimate goal is to simply reduce energy use by half of what the average household uses. The equipment chosen is an Eemax Electric Tankless Hot Water Heater. A solar hot water panel mounted on the dormer heats water through glycol exchange. A tankless electric hot water heater 1) boosts the solarheated stored water if it is below desired temps and 2) provides back up water heating during cloudy periods.
With the alarming growth in the energy costs and environmental concern in construction projects there is a continuous demand for sustainable buildings. LEED® evaluates the sustainable performance through a 69-point credit system which mainly emphasizes Indoor environmental quality, energy and atmosphere, sustainable sites, water efficiency, materials and resources and innovation in design (Azhar, Carlton, Olsen and Ahmad (2011)).
I knew that there was a lot of heat seeping through my attic and walls. There was just too much warm air escaping during the winter, and we never could get totally warm on the coldest nights. My brother told me about a better material to use than my old fiberglass batt insulation. He suggested using spray foam insulation to fill spaces between the studs in the walls and attic. Once it is applied, it expands to over 100 times its original volume so it effectively seals any gaps and cracks to the outside. ...
If your house or building was built after the 1920, the chances where that the external walls of the building were built too have a gap with no air in between them (Vacuum) or filled with a thick yellow mixture called Cavity Wall Insulation. Cavity Wall Insulation grants you the chance to save on heating bills, and keep your house warmer. Cavity Wall Insulation (Micafil Material) may be a bad conductor, however it is a great insulator, allowing us to keep our house warm in the inside, and not allowing the cold air to get into the house. In this essay i am going to be talking about why Cavity Wall Insulation is important in our daily lives, how it is installed, and how it makes our house quieter.

There have been many means and methods in the past decade, fostered to ensure that the construction of buildings, complexes and many enormous structures are made with energy saving measures such as heat dispersal during the summer, and to also ensure the promotion of environmental sustainability such as the control of carbon emissions and greenhouse gases. And by the use of complex and highly innovative building materials like carbon fiber, such feet can be achieved.

Household energy conservation is a very practical and realistic approach to conserving energy within our society. US households consume a tremendous amount of natural gas as well as electric energy. It has been calculated that the amount of energy consumed within the US increased exponentially from about 1850 to 1975. If energy continued to increase at this rate, we would be experiencing severe energy shortages in our current society. Luckily, steps towards conservation, including various energy regulations, have curbed that growth somewhat, brining the predicted 160 Qbtu/yr for the year 2000 down to around 93.8 Qbtu/yr by the year 1996. However, household energy usage is still a major issue as households consume about 38% of the total consumed energy and contribute greatly to natural gas consumption and issues such as global warming. Therefore, it is important that people understand how we use energy in the household and what steps can be taken to conserve that energy.
Life changed immensely in the 20th century as air conditioning and refrigeration systems became more efficient and controllable. Air Conditioning and Refrigeration play important roles in providing human comfort, food processing, storage, and many other industrial processes. We chose this topic because our life would be difficult without AC and Refrigeration. This paper will talk about the history of air conditioning and refrigeration, the role of engineers in designing and building it, people’s life before and after air conditioning and refrigeration, and finally Applications in the area of achievements and future developments.
