New Approach to Building Ventilation and Cooling

July 17th, 2010

Industrial Pressure Blower Co. suggests a few methods of effective building ventilation and cooling. In industrial plants where there is a high density of employees and many manual operations involved, an improvement in the environment can produce substantial benefits in terms of increased production, reduced errors, and a decline in complaints and absenteeism among employees. In other circumstances, the attentiveness of an audience or student group may be a factor that spells success or failure for the project.

To obtain a reasonable degree of personnel comfort in hot weather, there are three basic factors that should be provided for in the ventilation and coolong system of a commercial or industrial building.

REMOVAL OF EXCESSIVELY HOT AIR

The first step toward controlling the hot air porblem is to provide for the removal of excessively hot air from the building. This superheated air frequently mixes with the air in the cooler areas of the building to produce an overall temperature increase. As superheated air is frequently localized around heat-producing machinery, it should be exhausted from the building near its source.

SUPPLY COOLER AIR

As a rule, outside air temperatures are considerably cooler than those inside a building. As superheated air is exhausted, provision should be made to replace it with fresh, cooler, outside air. When high temperature air is replaced by outside air, a substantial improvement in the average ait temperature of the building results.  Even where outside air temperature may be in the 80s or 90s, invariably it is 15 degress to 20 degrees cooler than the air it replaces. This is a very important improvement to the individuals affected.

VENTILATION

A very effective way to overcome the discomfort of a hot, stuffy room is to create a breeze. The circulation of air over a person’s body immediately causes a cooling effect on the skin. When air is passed over a moist surface, it will evaporate some of the moisture and thus lower the temperature of the surface. This is precisely what occurs when air circulates across the human body. By creating a gentle breeze throughout a room or area, a great deal of cooling comfort is provided for individuals who must work there. This pattern of air circulation is sometimes called “breeze conditioning”.

Commonly available prcatical methods of plants cooling are:

* Exhaust fans or Power Roof Ventilators (PRVs).

  To do a satisfactory job of eliminating excessively hot air, it is usually essential to have powered wall and/or roof exhausters. These fans should also help to control air pressure within the building whether it be negative or positive pressure.

* Supply Fans or PRVs.

  A large number of buildings use exhaust PRVs to exhaust fumes, smoke, dust or other contaminants unavoidable in the operation of the business. As a result, these buildings are frequently under a severe negative pressure. The solution to the problem of this kind is usually found in the use of supply fans or “make-up” air ventilators.

* Air Circulators.

  If the exhaust and supply air requirements of a building have been carefully engineered and installed, and there continues to be a high instance of worker discomfort, the problem usually relates to the matter of air circulation. In this way, in addition to amximum benefit from the fresh, cooler air, occupants receive the added comfort of air circulation over their bodies and they are not adversely affected by the superheated air being exhausted from the building.

The Gains of Using Construction Project Management Software

July 17th, 2010

When a construction business is growing, more transactions are dealt with, volumes of documents are processed and schedules on different projects are set with the corresponding estimate on the budget and the number of workers for the job. These are the common tasks that must be organized by the contractor in order to pursue the plan. The use of spreadsheets and large piles of documents placed in boxes are the traditional methods of managing a construction industry. However, with the dawn of the computer age, companies have adopted the use of Construction Project Management Software.

If you would follow the traditional way of using spreadsheets and different kinds of programs, all your files will be scattered and it may not pass your knowledge that other files are already lost. You would not want this to happen to you especially that a construction work requires evident documents that can be visibly and conveniently used by workers if they want to. Having only one software and source for all your files keeps them monitored and organized.

Lastly, take control of the whole issue when it comes to money matters of the construction project with the aid of the construction project management services. Using a single and standard software help you track down all the expenses that you made on the whole project. This alerts you to take several measures when there is a need to change some plans due to any problems on the cost. You can also use the accounting plans for future projects if it went well with the previous ones.

The Construction Project Management Softwares indeed a useful tool for all the companies involved in the construction industry. Having your own standard tool gives you the confidence that you can take control of your files and project costs. Moreover, you can manage and organize your plans on the whole project and provide employees with common information with the use of the software.
