New requirements regarding natural ventilation, exhaust systems, and the IAQ Procedure are included in the newly published 2010 version of Standard 62.1. ANSI/ASHRAE Standard 62.1-2010, Ventilation for Acceptable Indoor Air Quality, sets minimum ventilation rates and other requirements for commercial and institutional buildings.
“Since first being published in 1973, the standard has provided the basis for ventilation system design throughout the industry,” Roger Hedrick, committee chair, said. “The 2010 standard furthers ASHRAE’s work in ensuring acceptable indoor air quality, while also heeding the need for energy efficiency as we strive to find ways to help designers tailor ventilation system designs to each particular application.”
Among the changes to the 2010 standard are modifications to the Natural Ventilation Rate Procedure, which now requires most buildings designed to meet the natural ventilation requirements also include a mechanical ventilation system designed to meet the Ventilation Rate or IAQ procedures. The mechanical system is to be used when windows are closed due to extreme outdoor temperatures, noise, and security concerns.
“Most buildings using natural ventilation in the United States are high-rise residential buildings that often have no form of outdoor air intake other than operable windows,” Hedrick said. “This results in buildings with inadequate ventilation, because occupants often leave the windows closed in order to run the air conditioning, keep out noise, etc. The committee felt it needed to strengthen the existing prescriptive requirements to ensure adequate ventilation and their corresponding IAQ benefits are available to occupants.”
Another change relocates requirements related to exhaust systems to a new section, clarifying that exhaust requirements apply to all buildings regardless of the procedure used to determine outdoor air intake flow rates.
The IAQ procedure, which allows for the calculation of the amount of outdoor air necessary to maintain the levels of indoor air contaminants below recommended levels, has been made more robust by increasing requirements for using the “similar building” design approach and clarifying other requirements.
“The standard now contains, in informative Appendix B, a table of volatile organic compounds that designers might want to consider as possible contaminants of concern,” Hedrick said. “To encourage designers to consider ‘additivity’ when applying the IAQ Procedure, some guidance from the American Conference of Governmental Industrial Hygienists has been included.”
The cost of Standard 62.1-2010, Ventilation for Acceptable Indoor Air Quality, is $69 ($59 ASHRAE members). To order, visit the ASHRAE Bookstore.

Benefits of Hiring Tower Cranes
Every construction site is surrounded by a wide array of equipments. If a tall structure is being built at the construction site then you would definitely need Tower cranes. Such cranes are generally fixed to the foundation but at times they can also be attached to the side of a structure for easy maneuverability. Any sort of crane is utilized in lifting heavy weights but with Tower cranes you get the extra advantage of lifting weights to or from extremely high places. For all your construction purposes you definitely need a crane, which you can either buy or hire.
Construction sites and industrial sites definitely need Tower cranes but since they are hugely expensive the other best option is to hire them. Big companies may even buy cranes as it would tremendously help them in their business but for small companies it is simply impossible to buy cranes. Hiring Tower cranes eases your work and transporting such cranes from one location to another will not be too expensive. Such cranes are locally available for hire at several places and small companies can avail the hiring benefits of such cranes at very affordable prices. Sometimes even big companies opt for hiring cranes as they are much more convenient and easy to get when their work sites are located at considerable distances.
Renting companies of Tower cranes are professionals who take full responsibility for transferring or shipping and assembling of the cranes. Later, when the job is done, the shipping company will also dismantle the cranes and take it away with them. Hire charges include this assembling and dismantling charges but you don’t have to worry about paying anything more.
The working mechanism of the Tower cranes includes a central mast, attached to which is the slewing unit of the machine that acts as the motor of the unit. The slewing unit of the machine helps in movement of the arm part of the crane and lifts up objects by moving a full 360 degrees and lifting objects from one place and putting in down at another. The operation of cranes is quite easy but the movement of cranes is tedious and requires a lot of time. The mammoth weight of the cranes makes it next to impossible to shift cranes from one place to another; this is another reason why big companies prefer to hire Tower cranes rather than to buy them.
Another advantage of hiring Tower cranes is that it offers versatility to the business. Often at construction sites different types of cranes are required and because crane hire companies carry a wide variety of cranes it is always advisable to contact them for you are the specific type of crane that you need for your job.

Hazardous signs are meant to keep people safe from any types of danger that are almost always at hand. These can be seen anywhere. You can see hazard warning signs along the dangerous curves of highways, commercial buildings, factories and industrial plants.
There are many types of hazard warning signs that are principally made to conform to the standards set by the Occupational Safety and Health Administration, OSHA. Safety signage is often seen at the workplace. Generally, signages are often part of office cleaning supplies because most often it is only purchase when the need arises.
The different types of safety signs depend on where it is mounted and the purpose it shall serve. Certainly, it also conform to the standard regulations pertinent to its design, particularly the color of the safety signage. The additional information showing the different types of hazards also makes it more effective.
Here are the 4 most important hazardous signs and their specifications:
1. Danger Signs
This sign is often use to emphasize an eminent and immediate danger or hazard with probability to cause sever injury or even death. These are often identified with the triangular shape. This is one of those hazard warning signs often easily recognized with an exclamation point emphasizing eminent danger within the perimeter where it is mounted.
2. Warning Signs
This is one of the hazardous signs that show a potential danger which may result in serious injury or death, if not avoided. These signs are made to make people more aware of the dangers within its perimeters. Posting these signs will enable people to take appropriate action to avoid a potential danger like being able to exit safely from a building in case of fire. By posting these signs, people are able to practice caution, when approaching a dangerous area. Individuals are also able to exit safely in the case fire.
3. Caution Signs
It is use to indicate potential hazards that can cause injury but certainly not resulting to death. These are often seen in construction sites. One good example of this safety sign is the wearing of mandatory safety gear in certain areas when you need to get inside a construction site or industrial plant. Another good example for this type of hazardous signs is “hard hat area” which is often seen in construction site.
4. Prohibition Signs
As the name suggests, it is used to strictly implement some restrictions in certain areas especially in the workplace. Good examples of these safety signs is the “no smoking” signage especially mounted in areas surrounding flammable materials like gasoline or liquefied petroleum gas. These signs are often seen in a circle having diagonal line on it.
These are just four of the many different types of hazardous signs which are commonly seen in the work place. These safety signs are all very important to keep everyone safety at both at home or work all the time. Having these signs posted in the most appropriate places can definitely save life. Hence, it is important to observe much caution in deciding where and what the appropriate one you need to have before you purchase any of these hazardous signs.

Sustainable construction, also known as “green” construction specifically looks at sustainable design by architects and other designers keen to reduce the environmental impact of a building over its entire lifetime; it also addresses the use of sustainable ‘eco friendly’ or ‘green’ building materials – products that have been developed for use without causing damage to the environment.
In the past, constructing sustainable buildings was often seen as an indulgent statement and prohibitively expensive but with the advent of new building regulations and a focus on energy efficiency and climatic change, more and more companies are, in some way or other, addressing their corporate and social responsibility and incorporating some sustainable credentials into their business practices. This often includes ‘in house’ training programmes that aim to educate building professionals in the use and installation of new sustainable products and technologies.
Consumers too, are more ecologically aware and interested in sustainable living. As such, they are building sustainability into their designs and specifying more sustainable building products in their projects. These range from timber construction and sustainable roofs to internal fittings such as sustainable flooring, renewable energy sources and heating systems. Recycled materials such as Swish Gutters made from 85% recycled plastic bottles and YBS Non-Itch Loft Insulation is testament to the latest products coming to market to meet these demands.
Such construction is often overseen by service contractors who specialise in sustainable construction methods but as attitudes change and more and more building professionals are making it their business to change their working practices, new business opportunities are arising as a result. It is a strong likelihood that environmentally friendly construction methods will be more commonplace in years to come. This is, in part, driven by Government Initiatives and guidelines such as ‘Code for sustainable homes’ and The Strategy for Sustainable Construction that advocates sustainable development, renewable construction and ultimately zero carbon homes by the year 2016.
It remains to be seen as to how quickly these developments will be fully implemented, but suffice it to say that sustainability in construction is certainly here to stay.
