EWC Controls For Improved Air Quality And Comfort In A Building

By Coleen Torres


Air quality has been found to be one of the most important aspects of comfort in any building or house. This is a fact that can be supported by research findings. Heating, ventilation, and cooling systems in houses are the ones responsible for maintaining this aspect of comfort in the house. They play this role through zoning, an area in which EWC controls are one of the most reliable components.

In zoning, the house or building is divided into numerous zones. In each of these zones, there are thermostats that control the temperatures of a specific area. The thermostats are controlled by a central operating system. After setting the desired temperatures for the different sectors, the zoning system will maintain them as they are.

The use of a single thermostat for the whole house can never be efficient. One will find that the conditions comfortable, for instance for the bedroom are not the same that are suitable for the kitchen. This results in a situation where one is uncomfortable in some areas of the house and comfortable in others. This means they will have to adjust temperatures whenever they move.

The need to make constant adjustments as one moves from one room to another is never present with the zoning system. Zoning is very efficient. Using a single thermostat is very tedious with the changes that have to be made. Using an air conditioning system can be very expensive, because they often consume a lot of electricity.

Using an air conditioning system consumes a lot of energy, and adds to the expenditure on heating or cooling. It has been found that a typical family will spend at least 40 per cent of their income on heating and cooling. Using a zoning system can reduce this number by about 30 per cent. However, there is much more to HVAC than just temperatures.

Dampers are an easy way of controlling the quality of circulating air. In large buildings, they are the preferred choice to air conditioning systems because they are cheaper. They regulate the aspects of air quality that thermostats and temperature zoning systems cannot adequately control by controlling the temperature. There are both manual and automatic ones, which are self-regulatory and require no input.

There are numerous advantages of zoning apart from the obvious convenience and energy expenditure reductions. They help the owner of a building or house achieve what scientists call the comfort zone. This is a set air quality percentage that they consider to be comfortable for majority of people in a house or building.

There are many advantages of zoning systems in HVAC. They help the house owner achieve the comfort zone. This is the level of circulating air quality that scientists have determined to be comfortable for about 80 per cent of typical building occupants. They are cheap and comfortable, reducing the energy expenditure while improving the comfort of occupants in an office or a home. Poor quality of internal air circulation is also bad for health of people. It might make it easy to contract airborne diseases or affect the health of the elderly and very young kids.
