It’s cold throughout MD, VA, and DC now, but the weather will soon start to change. Before you know it, it’ll become warmer, which means you should begin thinking about attic fan installation. An attic fan is a ventilation fan that regulates the heat level of a building’s attic by exhausting hot air. It is similar to a kitchen fan but located in the attic of a home. An attic fan is usually connected to a switch or string that you can access from the top floor of your home. You may be surprised to learn about all the benefits of installing an attic fan in your home.

Attic fans are key to maintaining an energy-efficient home. Your air conditioning unit will have to work overtime if you allow rising heat to stay in your home instead of routing it up and out. This ultimately reduces the unit’s efficiency. An attic fan is an excellent home cooling option that also keeps your energy bill down in hot summer months.

An attic fan helps reduce the humidity, or overall moisture level, in a house. Daily household activities—showering and cooking, for example—create moisture that rises and can build up in the attic if the space isn’t properly ventilated. If you don’t take any action and allow this moisture to sit in the attic for an extended period, it will eventually create mold in the insulation and possibly even in the wood structure of the attic. This moisture can be especially damaging during the wintertime (now!) when cold turns it to ice or frost. The expansion of ice and frost can seriously damage your roof.

An attic fan helps combat moisture and transfers it out of the attic before it can cause serious damage to insulation, wood structure, and roofing materials. Now is the perfect time for attic fan installation—it will help prevent ice or frost from forming and damaging your roof, and you’ll need an attic fan for the warmer months anyways.

Maintenance Factor

Illumination Systems are designed to fulfill the required lighting level at the end of an operation term and not at day one of the new installation. The luminous flux of the system is going down over lifetime. This is a normal process, no product is lasting forever but the required illuminance levels should not be depreciated at any time. If a lighting system is setup, the maintenance plan has to be fixed too. So the facility managers know how often to clean the room, the luminaries and how frequently to change lamps. A reasonable time needs to be found between maintenance and operating hours, as maintenance cycles are connected to costs. The longer the operation time without maintenance, the more luminaries need to be installed to guarantee the required illumination level at the end of the term. The more frequent the maintenance cycles, the higher the maintenance factor, but also the related costs for the facility service.

Which Points are influencing the Maintenance Factor? Different factors influence the decrease in lighting level like the soiling of the room surfaces, the soiling of the luminaries, depreciation of luminous flux by the light sources or lamps failure.

Room Surface Maintenance Factor: The room surface maintenance factor is the ratio of the room surfaces reflectance before and after cleaning. It is the reduction of the lighting level according to soiling of the room. Luminaire Maintenance Factor: The luminarie maintenance factor is the ration of the luminaries luminous flux before and after cleaning. It depends on the luminarie construction and design (open housing or closed one) as well as on environmental conditions (dirty or clean). Lamp Lumen Maintenance Factor: The lamp lumen maintenance factor is the ration of luminous flux at a specific time compared to a new lamp. It is describing the aging of the lamp or the reduction of light intensity over time. Manufacturers offer comprehensive tables about their lamps luminous flux behavior. Lamp Survival Factor: The lamp survival factor depends on the service lifetime of a lamp. Some lamp lifetimes are reduced by frequent switching. The lamp manufacturers provide tables indicating the lamp survival factor. If a lamp is not working any more, the decision for immediate replacement or group replacement needs to be taken. If the lamp is replaced immediately (mostly in areas where the luminaire is easily reachable) the LSF can be set 1. On the other hand, the decision could be to replace lamps in special terms or group-wise. This could be the case in huge halls, where machines need to be stopped to reach the luminaires.

A maintenance factor of 0.8 shows, that the new lighting system needs to be over driven by 25% not to undercut the minimum required illumination level after 10 years. LED lighting systems are flexible and easy to connect to control systems. The installed load will provide efficient luminous flux at the end of the operation time but the energy that is “over” in the beginning can be saved. The new installation would illuminate an area with required 300lx by about 450lx. The energy can be saved by lighting management systems that are regulating the power concerning the luminous flux depreciation. HID lamps are not easy to control. The energy load that is “over” in the beginning is wasted. No change to save it.

Conclusion: Think carefully when setting up a lighting installations maintenance plan. This starts already with the choice for the light source. LED Modules are efficient, likely not failing and offer long lifetimes between 50,000h and 100,000h. The control possibilities are comprehensive. The luminaries overload, that needs to be installed to guarantee the end of lifetime illuminance levels, can be saved by light management systems. Regarding all the mentioned points, LED is the competing light source. The features are dominant over traditional light sources. Take the chance and install or renew your lighting system by  energy efficient LED light sources and luminaries.

LED lights are also measured in two different ways; by their color temperature and the lumens they produce. Because they use significantly less power and are gaining in efficiency with each generation, whereas older bulbs are consistent in their wattage being representative of the amount of light put out, LED bulbs can vary in efficiency a bit more. What this means is that the bulbs are now rated by their Lumen rating, or how much light they put out, versus how much power they draw. Understanding how LEDs work and the opportunities that they present to you as a homeowner are key to helping you make a decision as to how you light your home.

It can be annoying, frustrating and disappointing to decorate for a holiday season, party or event and after everything is set up you discover your outside electrical outlets do not work. The kids are ready to see all the lights or the party planner is near to crying. This was an important time for them and you want to know why the outlets are dead.

What you can do on your own

Is this an unusual occurrence?

Some advertisements for goods on television tell you it has a lifetime guarantee. Very few things are built for lifetime use. Even an electrical outlet can suffer from wear and tear and even environmental circumstances.

While you may have outlets that have protective covers that are supposed to shield them from rain, snow and humidity, dampness can get in and damage your outlet. It could also be that some of the wiring has burned and will not function properly. There is also the possibility that the outlet was not installed by a professional and that it is not up to code.

Before you call your electrician, unplug the cords from the outlets. Do not allow anyone near them or try to do a DIY project. It goes without saying that when you are dealing with electrical problems there could be a danger to you and your family. You want your house to be festive but not burned down.

What will the electrician do?

You repair person will listen to the information you have gathered. He will ensure that the power is shut off to the affected areas prior to opening the outlet to begin work. He will check the actual outlet and the wiring. He will determine whether the problem is limited to the exterior only or if it can or will cause an interruption on the interior of the house.

You’ve heard of bugs in computers? Some types of insects can set up housekeeping behind your electrical outlet and wreak havoc. The repairman will open the outlet after the power it cut and may even have to go into the wall to make a final determination.

He may be able to repair the wiring to the outlet. He will recommend a course of action. It may be that the outlet is damaged beyond repair. Your service person will tell you about the outlets that are available that are identical and also show you others that may be more enhanced or updated. It will be your choice.
