Solar Panel Installation Services

 What does "Sustainable" mean - it means that you are using far less energy produced from fossil fuels that have to be yielded from the earth by drilling, or mining for them. And if you have to use materials that you have to mine and refine that those materials remain preserved and can be re-used at the end of life so that they do not have to be mined again. For example, most of the world's aluminium need can be satisfied with aluminium re-processed from scrap. Low load-bearing foundations and walls can use crushed concrete for ballast when available. There are many crushing and concrete recycling services available today which can easily be found when searching for "recycled crushed concrete". You can also use Recycled Asphalt Pavement and Crushed Concrete as backfill for Mechanically Stabilized Earth Retaining Walls.


In the context of "Green Sustainable Architecture", this can mean correct positioning of a building versus the prevailing wind direction, run-off  Solar Panel Installation Services water management on the property, wall and roof insulation, and avoiding roof penetrations. Those are some of the passive measures that can be taken at the design stage of a new building to make it more sustainable.


In the context of "Heating and Cooling" there are slightly different requirements on sustainable Heating and Cooling Systems depending on the climate-region. There are also significantly different Systems that can be deployed which will have significantly different requirements for the infrastructure the building has to provide.


The most significant factors for both heating and cooling are loss of heat or cool through walls, windows and ceilings. This has to be addressed architecturally by designing with good or very good insulation materials and the really good ones may not be from recycled materials but are end of life recyclable as ballast.

The plenum between floors should be well insulated to the outside walls and contain the infrastructure for water-loops rather than air ducts (or both) as well as a 48V-DC electrical distribution system which allows the use of 48V-DC based heat pumps and 48V-DC based lighting equipment.


The reason for using DC based systems is that:


LED lighting running of DC can run with an efficiency of 98% while

AC based LED lighting systems run with an efficiency of 85%.

Any Watt in heat generated requires a Watt to pump it out of the building, in the case where the air space needs to be cooled. The energy wasted by lighting has a direct and significant impact on the energy required to cool a building that is well insulated.

The same applies to the heat exchanger when the heat pump itself is located in the building.

DC based systems can use Solar and Wind Generators to charge Batteries for storage,

the Grid or a Generator can supplement the batteries.

The highest loss of efficiency of conventional air conditioning systems for heat or cool is in the air duct. Therefore for highest efficiency and sustainability heat exchangers should be in each room. The heat exchangers may include heat pumps which for noise reasons may use solid state heat pumps which require little or no maintenance other than air-filter maintenance. This is the most efficient way to cool or heat the air in the room.

Air Conditioning Service Los Angeles

 More than one million homes in the United States today have installed geothermal heating and cooling systems. The US Environmental Protection Agency has stated that geothermal provides the cleanest and most efficient way to heat and cool a home today. Geothermal means heat from the earth. Our planet can provide a continuous source of heat and energy both near the surface and deep within the ground. Geothermal systems use the earth's natural ability to   Air Conditioning Service Los Angeles    store solar energy. Mild temperatures exist in steady supply at depths ranging from six feet to a few hundred feet below the surface of the earth. A geothermal system captures these moderate temperatures to both heat and cool homes. The main component of a geothermal heating and cooling system is the ground source heat pump. Heat pumps transfer heat from one source to another. When mild temperature fluids are used, as they are with geothermal, the heat pump becomes even more efficient. There

Rodent Control Methods

 Many homes are equipped with heat pumps as their heating and cooling system. Heat pumps work well at most temperatures; however, in extreme temperatures they may not provide the comfort level you expect. The following are some operating and maintenance tips to help you set realistic expectations about heat pumps and to maintain the system at peak energy efficiency and operating effectiveness. Heat pumps absorb heat from one place and transfer it to another. In air conditioning mode, they absorb heat from inside the home and transfer it outside. In heating mode, they absorb heat from outside and transfer it inside. This process works    Rodent Control Methods     when the outside temperature is between about 40 and 95 degrees F. It is more difficult for the system to maintain comfortable interior temperatures when the outside temperature is beyond this range. Older systems and systems that are poorly maintained may have a narrower outside temperature range within which they can maintai
