Annual Performance Review

!9# Annual Performance Review

[if ]
[endif]

You need to ensure your staff is happy and the best way to do this is to complete annual performance reviews. These reviews are required to ensure your team members are happy in their role and to ensure they are striving to meet their goals. This is also a good opportunity to communicate any concerns to either party.

An annual performance review is an ideal way to gauge the effectiveness and the moral of your team. You may have to get them to speak or encourage them to tell you the truth. Reviewing your team's performance can improve your business's productivity.

What types of things need to be discussed in a performance review? This really depends on the person's role. Is it a complicated role or a simple role? Either way, you need to make sure you cover all aspects of their role. This means going through their daily tasks and the things they do well. You should also address the negatives. It is recommended that you start off with the positives first so they do not feel threatened.

Reviewing your team's performance should be an experience that is positive for both parties. If it is negative, then it is likely that one of the parties is not happy and should probably move on. Lastly, the salary should also be discussed when talking about people's performance. It is usually the last item discussed. If you are reviewing your team's performance then you should consider using an annual performance review template.

Sizing the Energy Efficient Pool Pump

!9# Sizing the Energy Efficient Pool Pump

[if ]
[endif]

There are two main categories of swimming pool pumps from which to choose. You can either purchase a single speed or a variable speed design. Doing the pump sizing calculations can also help you understand what type to purchase for greatest energy efficiency. Let's do an example of sizing the two different types to illustrate the point.

Let's say you own, or are going to build, a fifteen thousand gallon pool and you want to turn the water over in the pool twice per day. That means your pump has to move 30,000 gallons of water per day (pool size times turns per day).

In our first example we are going to purchase a constant flow pump that turns itself on and off once per day. So, let's say you set the pump to run during the night when energy rates are at their lowest. You want the pump to run for six hours every night. Therefore, in six hours time the pump must move 30,000 gallons of water. If we convert six hours to minutes (6x60) we have 360 minutes. Thirty thousand gallons of water moved in 3600 minutes means you need to purchase an 83 gpm pump or larger. To make the pump smaller you can cycle more times per day.

In our second example, let's illustrate a variable speed pool pump which will run constantly throughout the day. You have the same fifteen thousand gallon pool that you want to turn every twelve hours or thirty thousand gallons of water to move daily. However daily is going to be 1440 minutes instead of 360 minutes as in the example using a single speed pump. Thirty thousand gallons divided by fourteen hundred forty minutes is 20.8 gpm or larger.

Now, here's the bonus for you. Not only can you purchase a smaller pump which saves on material and room but the smaller pump will keep your pool water healthier and save you money on energy. As for the health of your water it is easy to see that cleaning and mixing your chemicals constantly is better than letting the water sit and mixing it every so often with cleaning and chemicals. As for the energy savings, the physics of water hydraulics is it takes less energy to move water slowly than quickly. The speed of the water compared to the energy needed is an exponential, not linear, relationship. Savings of up to forty percent have been documented when installing variable speed pool pumps. The capital expense is sometimes greater but the long term savings will almost always go toward the energy efficient variable speed pool pump.
