What is bioclimatic upgrading of buildings
Bioclimatic upgrading of buildingsis the redevelopment of a building with bioclimatic interventions. Namely invasive ways to improve its thermal performance, providing cool in the summer and warmth in winter, utilizing solar energy and other environmental sources such as land, air, and water.
Bioclimatic design is essential in every building so that it can be upgraded. We examine the site of the building in the area where it is located as it interacts with the microclimate of the local environment and influences our decisions on the following principles:
What is geothermy
Geothermyis one of the most important forms of renewable energy. It is the exploitation of the constant temperature of the ground materials that exist at low depth, allowing, with the help of a geothermal heat pump the transfer of heat to and from the ground for the production of heating or cooling.
Geothermal energy has been used for many years in Western countries through geothermal heat pumps. These systems operate by taking advantage of the constant temperature of the earth in order to pump energy and heat a building or to emit heat and cool a building.
Systems operating with the use of geothermal heat pumps include three parts:
In addition to the pipeline network, the groundwaters in the area, the water of a lake or even the sea can be used. Then the geothermal heat exchanger is called an open circuit alternator.
The operation of this system is similar to that of air conditioners, the difference being that air conditioners use the outside air temperature by evaporating the volatile gas that they contain while the geothermal pump uses the water temperature.
Depending on the environment and the needs of the building, the form of the geothermal heat exchanger, which will determine the final installation option, is defined
Forms of the geothermal heat exchanger
An open system is also applied in the event of the exploitation of lake or sea waters.
The advantages of geothermal energy are:
What is solar thermal
Solar thermalis the technique of converting solar energy into thermal energy.
The use of solar energy for heating water is one of the oldest uses of solar energy.
In 1908, William Bailey of Carnegie Steel Company (USA) invented a collector with an insulated container and copper spiral tubes inside (the well-known water heater). By the end of the First World War, Bailey had sold 4,000 units. Later, when a Florida businessman bought the patent rights, he sold nearly 60,000 units by 1941. However, the restrictions of copper sales during the Second World War led their purchases to a sharp fall.
In Greece the spread of solar systems took place in 1974, following the oil crisis of 1973. At that time, there was an increase in the newly established industries, reaching a peak in the 1980-90s.
The principle of the operation of all solar thermal systems (THS) is simple.Solar radiation is converted into heat that is collected and transported through a liquid fluid. The heat is used either directly or via an alternator and is transferred to its final use.
Solar radiation is used in a wide range of applications including:
The advantages of solar thermal is:
- Environment-friendly technology without emissions of gaseous pollutants.
- Operation all year round
- Fuel savings and autonomy
- It does not remove the existing heating system, but it also combines them
- It is compatible with common radiators and underfloor heating
- Ability to use electrical resistance with night-time automation with charge of the night invoice
- Ability to enable with mobile
Fireplaces & Stoves
They have been the traditional way of heating since the man discovered the fire. Originally, the fireplace was located in the center of the room and later, in its present form, tangent to the wall. There has been a great development in this field and a wide range of options is now available in the market.
