GreenTip #28: Passive Solar Thermal Energy Systems.

The essence of solar designs is to exploit the natural sources of energy like solar, climate and materials to economize on the energy use in the buildings. This tip provides an overview of how to go about designing the solar buildings, from the site selection to the human resource employment. It states that the site selection should be insightful enough to determine the future use of eth site before constructing any building. The passive solar home is a special type o design that provides a more convenient home energy using the renewable solar energy. Typically, the home design takes into consideration the windows design and material use that can trap the maximum thermal mass. Specifically, the orientation of the window should be 30 degrees true south without shading. The appropriate thermal masses to employ include concrete, stone, and tiles. These material absorb heat. The roof overhangs are properly constructed to allow for proper emission. The heat transfer in the house is enabled through conduction, convection, and radiation.

GreenTip #31: Solar Protection.

In this design, the domestic fluid system is heated using the solar energy trapped by the solar panels. The water heating could be for bathing and other uses. The system also heats the air and circulates it into the interior of the house to produce warmth. The storage of hot water helps in the preservation of energy. It can be achieved by constructing pressurized tanks mounted on radiant slabs. The most effective materials for the design of tanks are fiberglass, stainless steel, and high-temperature plastics.

This system can work appropriately alongside passive solar design. To make this possible, the passive solar design must take into consideration the distribution of solar energy by placing the solar panels on open areas of the compound. The design of the roofs should be in such a way that they allow for the trapping of solar rays. If this is so, the solar panels can be mounted on the rooftops.

This tip generally deals with how to construct arts spaces in a manner that saves both space and energy. It suggests the ideal methods for noise management, energy management, and cohort comfort.

GreenTip #29: Active Solar Thermal Energy Systems.

The main concern of this tip to elaborate how the homes can economize on energy use through designs that enhance insulation, windows, and mass. The strength of a passive house depends on its ability to provide insulation. The house loose heat majorly through leakages. To minimize the heath loss, the buildings are designed by increasing inches of walls. More energy is saved if the building adopts a tailoring insulation. It maintains the interior temperature at 68F while the exterior design temperature is10F.

Thermal mass, as discussed earlier is the use of materials which can absorb energy to minimize heat loss. Among the cited materials are concrete, stones, and tiles. The design should be in such a way that the floor is about 4 to 5 inches. This maintains the home temperature beyond 2F.

The windows, on the other hand, should be facing the north at around 30 degrees. To conserve more heat, there are special designs of windows like LoE-180 glazing, with a U-factor of 0.26 and SHGC of 0.69.

Green roofs. GreenTip #30: Solar Energy System. The misconception that using solar energy for your home means you need photovoltaic (PV)

A design that employs passive solar technology incorporates the most modern technologies to carefully craft the overhangs and reflective coatings on the windows to harness the natural energy. In as much as there have been misunderstandings on the relationship between passive homes and the use of photovoltaic, the truth is different. Today, a passive home can easily harness the solar energy without the employment of photovoltaic technologies of converters and other gadgets but instead use the passive solar design to trap this energy. The success of this starts with the design and orientation of the windows, the thermal mass, the strategies of control and the mechanisms of distribution. The home design must take into consideration the distribution of solar energy. This includes the distribution and the height of trees, the direction of the sun and other obstructions. Most importantly, one must ensure that the home receives the optimal sunlight. The house can achieve this easily if the windows facing to the south are clean enough.

First graph

Passive houses derive their names from their ability to conserve heat through such process as a passive use of energy, insulation, internal heat sources, and heat recovery. This technology is a brainchild of Passive House Institute (PHI). A standard passive house exhibits such characteristic as energy efficiency (reduction of eating loss by up to90%), the quality air in the indoor, comfortable and affordable. From the graph, a comparison of heat loss by the old houses, low energy buildings and passive houses reveals that the passive houses lose heat the least. The highest energy consumption by old houses is as high as 240kwh while the highest energy consumption in passive houses is as low as 30kwh annually. The low power consumption in the passive houses is due to the green technology incorporated in the buildings.

Second graph

The graph above compares the performances of different designs of houses in terms of energy and resources conservation. Visibly, the passive houses loose the least heat. The reason for this is that the passive houses have efficient insulations, they are free of thermal bridge free, have airtight windows, and maximizes the trapping of solar energy.
