Let's chat about 30-40% of your electricity bill. That's how much it costs the average homeowner or trailer building owner to come up with the money for proper heating, ventilating, and air-conditioning (HVAC). A fine HVAC system is the key to maintaining a comfortable, healthy and interior environment. Through the years, I have been asked by many owners for a strategy to cut their cost of liveliness and HVAC. They don't want to sacrifice the interior environmental conditions, but they reach want a point-by-point plan to follow. The interesting business that often happens is that liveliness bills are lowered substantially and the HVAC system statute is improved. This is a up to standard statute of any mechanical engineer specializing in liveliness and HVAC.

The opinion on this page will back homeowners, building owners and building operators create informed decisions about existing HVAC systems or difficult upgrades.

Load Reduction

The first step to attain liveliness and HVAC system optimization is load reduction. This step normally consists of a long range plan which itemizes the events to be taken based on best compensation on investment. Reducing your building load allows the existing HVAC system to statute more efficiently. If a extra system or systems are visceral considered, it will be more cost energetic to design for the edited load as opposed to the existing load. A few common load narrowing strategies include:

Tighten the building shell and grow extra insulation. adding up insulation in existing buildings may not be achievable in some instances, so more consideration should be aimed at the exterior shell, especially windows and doors.
Installing energy-efficient windows. This is a big item on some buildings that yet have single pane windows. The installation of double pane windows later a thermal rupture is a great compensation on investment. create determined they are liveliness STAR qualified windows. Tinting or Low-E coatings will even be better.
Upgrading lighting systems. The average trailer building has a lighting density of 2-3 watts per square foot which maintains proper lighting levels. This is a significant allowance of the HVAC load and as regards any efforts in this management will humiliate the cooling requirement for the building. Accent lighting (sometimes called architectural lighting) are not always liveliness efficient and should not be considered if you want to cut liveliness and HVAC costs. Energy-efficient lighting systems emit less heat into conditioned vent than older shining technology. If you have a compensation freshen plenum then again of compensation freshen ductwork, announce lively troffers so that some of the heat from the lights is returned to the HVAC system then again of going into the occupied area.
Selecting efficient equipment and electronic devices that have a facility squirrel option will cut the sensible heat gain in the space. Items to announce complement copy machines, kitchen equipment, computers and refrigerators.
Control drying by having your external freshen balanced. Most building owners have drawings of the indigenous HVAC system installation. Have the drawings reviewed by a mechanical engineer to establish your external freshen flow rates conform to the latest code requirements. If no drawings are available, your mechanical engineer should yet be competent to create recommendations for improvement.
Addressing these items is your first step to reducing liveliness and HVAC costs.

HVAC Systems

The second step to attain liveliness and HVAC system optimization is knowing your system. Your HVAC system is indispensable to your interior environment, but it next represents a large component of your foster expenses. even if it is greater than the scope of this article to discuss all system, a few recommendations can be addressed. all HVAC system component has increased in efficiency greater than the years. If your system is more than 13 years old, it's time to begin planning for an restore to extra equipment. competently maintained residential systems have a liveliness expectancy of about 15 years or so but seem to fail at the worse times. Have a replacement plan ready for the morning your equipment fails.

Commercial systems vary, but if your building is using packaged equipment or split systems, the similar lifetime can be expected. For larger trailer systems and industrial applications, the HVAC system may be more highbrow and require an individual analysis by a mechanical engineer. As I said, HVAC systems amend and no one-size-fits-all analysis works for larger systems. What all these systems have in common is they are normally fueled by electricity. Electricity cost money, so any efforts in the management of increased efficiency is a plus.

HVAC System Tips:

Find a qualified consultant you trust. If you are a house owner or small trailer building owner, locate a fine HVAC company or mechanic to evaluate and maintain your system. If you are a large trailer building owner, locate a trailer HVAC company for normal money and a fine mechanical engineer for specific guidance. I reach not suggest using a mechanical engineer employed by the HVAC Company; locate a third party engineer for radical information.
Verify your HVAC system load. house owners should use ACCA's calendar J adding together method and all others should have a load conducted by a mechanical engineer. trailer buildings have more requirements related to code conformance, minimum drying rates, etc and are individual to each building.
Load reduction-Read the opinion above.
Select equipment sized for your load. NEVER OVERSIZE! More-is-better does not apply for HVAC systems. It will cost more to purchase the equipment as competently as statute it. get the load and the equipment selection right the first time.
Purchase high efficiency or liveliness Star equipment. Many of the extra systems complement changeable keenness drives for fans and compressors. greater than the years of ownership this will be paid back many time over. Compare up to standard efficiency equipment to high efficiency equipment in terms of initial cost and liveliness cycle costs. Any fine HVAC company or mechanical engineer can attain this information.
Consider some form of liveliness recovery for any freshen exhausted from the building and use it to condition the incoming lively air. This is freshen you have paid to condition, so extracting some of the liveliness previously exhausting it should be a priority.
For large trailer buildings, announce conditioning the external freshen later a dedicated external freshen unit. This will eliminate any problems related to humidity rule in most instances. It will next growth occupant comfort and allow for extra downsizing of equipment.
Commercial buildings should announce economizers on their equipment. Most current codes require economizers on equipment greater than 15 tons in size. Often understandable at a low incremental cost, these units appeal in lively freshen from the external later the temperature (sometimes humidity) external is humiliate than the temperature inside.
Home owners and small trailer building owners should install programmable thermostats. trailer building owners should install a forward Digital rule (DDC) system. The investment in either of these will pay back more than the cost in a small amount of time. door more below.
Control Systems

The third step to attain liveliness and HVAC system optimization is controlling your system.

Programmable Thermostats-The age of digital controls has made saving liveliness easy. One of the best investments for the homeowner or small trailer building owner is a programmable thermostat. These are easy to use and incorporate strategies based on time scheduling. Most manufacturers come up with the money for 7 morning programs and setback/setup programs which will twist the HVAC system on and off to praise your schedule and desired indoor temperature. This is a great artifice to ensure HVAC systems are used forlorn later necessary.
DDC Systems-For the large trailer building, I announce this as a must have system. Installation costs have steadily decreased and the statute reliability has steadily increased. They can be integrated into any system and expanded as required. Some of the more popular features of these systems are optimized start/stop of the HVAC system, complex zone control, complex temperature sensor locations and drying control. The best allowance of these systems is their exploit to be scaled up to the largest of trailer applications. This means you can install a easy system and grow more controls difficult to incorporate your amass HVAC system. Again, the payback is gruff and competently worth the investment.
Operation and Maintenance

The fourth and last step to attain liveliness and HVAC system optimization is operation and maintenance. The most efficient HVAC systems are competently maintained. Ensure reliability, efficiency and a long liveliness for your HVAC system by later these tips.

Find a qualified consultant you trust. If you are a house owner or small trailer building owner, locate a fine HVAC company or mechanic to evaluate and maintain your system. If you are a large trailer building owner, locate a trailer HVAC company for normal maintenance. create determined you photo album and document all servicing later dates, time and names of the servicing person.
Home owners should always get a seasonal song up. The operation of your system will amend later the seasons of the year.
Replace your freshen filters regularly. Don't use whatever less after that a MERV 5 filter to assure dust and fibers are removed. tidy filters will save lover energy.
Coil Cleaning-This is always a big item overlooked by residential and trailer building owners. Condenser coils amass dirt and debris on their surfaces because they are outside. This makes the compressor statute harder and results in a difficult refrigerant temperature in your refrigeration system. Evaporator and heating coils amass dust and fibers that vent inside your house or building. tidy them at least later a year
