Let's chat practically 30-40% of your electricity bill. That's how much it costs the average homeowner or trailer building owner to manage to pay for proper heating, ventilating, and air-conditioning (HVAC). A good 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 reduce their cost of vivaciousness and HVAC. They don't want to sacrifice the interior environmental conditions, but they do want a point-by-point scheme to follow. The fascinating situation that often happens is that vivaciousness bills are lowered substantially and the HVAC system pretend is improved. This is a normal pretend of any mechanical engineer specializing in vivaciousness and HVAC.
The assistance upon this page will urge on homeowners, building owners and building operators make informed decisions practically existing HVAC systems or forward-looking upgrades.
Operation and Maintenance
The first step to attain vivaciousness and HVAC system optimization is load reduction. This step normally consists of a long range scheme which itemizes the activities to be taken based upon best reward upon investment. Reducing your building load allows the existing HVAC system to pretend more efficiently. If a new system or systems are instinctive considered, it will be more cost enthusiastic to design for the abbreviated load as opposed to the existing load. A few common load tapering off strategies include:
Tighten the building shell and accumulate new insulation. addendum insulation in existing buildings may not be achievable in some instances, suitably more consideration should be aimed at the exterior shell, especially windows and doors.
Installing energy-efficient windows. This is a big item upon some buildings that still have single pane windows. The installation of double pane windows when a thermal break is a good reward upon investment. make sure they are vivaciousness STAR endorsed 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 ration of the HVAC load and around any efforts in this supervision will lower the cooling requirement for the building. Accent lighting (sometimes called architectural lighting) are not always vivaciousness efficient and should not be considered if you want to reduce vivaciousness and HVAC costs. Energy-efficient lighting systems emit less heat into conditioned spread than older glowing technology. If you have a reward expose plenum on the other hand of reward expose ductwork, judge light troffers suitably that some of the heat from the lights is returned to the HVAC system on the other hand of going into the occupied area.
Selecting efficient equipment and electronic devices that have a capacity stasher unorthodox will reduce the sensible heat gain in the space. Items to judge put in copy machines, kitchen equipment, computers and refrigerators.
Control exposure to air by having your external expose balanced. Most building owners have drawings of the original HVAC system installation. Have the drawings reviewed by a mechanical engineer to establish your external expose flow rates conform to the latest code requirements. If no drawings are available, your mechanical engineer should still be skilled to make recommendations for improvement.
Addressing these items is your first step to reducing vivaciousness and HVAC costs.
The second step to attain vivaciousness and HVAC system optimization is knowing your system. Your HVAC system is critical to your interior environment, but it furthermore represents a large component of your minister to expenses. even though it is exceeding the scope of this article to discuss every system, a few recommendations can be addressed. every HVAC system component has increased in efficiency exceeding the years. If your system is more than 13 years old, it's epoch to begin planning for an modernize to new equipment. without difficulty maintained residential systems have a vivaciousness expectancy of practically 15 years or suitably but seem to fail at the worse times. Have a replacement scheme ready for the daylight your equipment fails.
Commercial systems vary, but if your building is using packaged equipment or split systems, the thesame lifetime can be expected. For larger trailer systems and industrial applications, the HVAC system may be more mysterious and require an individual analysis by a mechanical engineer. As I said, HVAC systems rework and no one-size-fits-all analysis works for larger systems. What every these systems have in common is they are normally fueled by electricity. Electricity cost money, suitably any efforts in the supervision of increased efficiency is a plus.
HVAC System Tips:
Find a endorsed consultant you trust. If you are a home owner or little trailer building owner, locate a good HVAC company or mechanic to explore and maintain your system. If you are a large trailer building owner, locate a trailer HVAC company for normal maintenance and a good mechanical engineer for specific guidance. I do not suggest using a mechanical engineer employed by the HVAC Company; locate a third party engineer for ahead of its time information.
Verify your HVAC system load. home owners should use ACCA's reference book J adding up method and every others should have a load conducted by a mechanical engineer. trailer buildings have more requirements joined to code conformance, minimum exposure to air rates, etc and are individual to each building.
Load reduction-Read the assistance 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 without difficulty as pretend it. acquire the load and the equipment selection right the first time.
Purchase high efficiency or vivaciousness Star equipment. Many of the new systems put in adaptable promptness drives for fans and compressors. exceeding the years of ownership this will be paid urge on many epoch over. Compare normal efficiency equipment to high efficiency equipment in terms of initial cost and vivaciousness cycle costs. Any good HVAC company or mechanical engineer can buy this information.
Consider some form of vivaciousness recovery for any expose exhausted from the building and use it to condition the incoming light air. This is expose you have paid to condition, suitably extracting some of the vivaciousness past exhausting it should be a priority.
For large trailer buildings, judge conditioning the external expose when a dedicated external expose unit. This will eliminate any problems joined to humidity run in most instances. It will furthermore addition occupant comfort and permit for new downsizing of equipment.
Commercial buildings should judge economizers upon their equipment. Most current codes require economizers upon equipment exceeding 15 tons in size. Often open at a low incremental cost, these units fascination in light expose from the external when the temperature (sometimes humidity) external is lower than the temperature inside.
Home owners and little trailer building owners should install programmable thermostats. trailer building owners should install a take up Digital run (DDC) system. The investment in either of these will pay urge on more than the cost in a little amount of time. entrance more below.
The third step to attain vivaciousness and HVAC system optimization is controlling your system.
Programmable Thermostats-The age of digital controls has made saving vivaciousness easy. One of the best investments for the homeowner or little trailer building owner is a programmable thermostat. These are easy to use and incorporate strategies based upon epoch scheduling. Most manufacturers manage to pay for 7 daylight programs and setback/setup programs which will direction the HVAC system upon and off to compliment your schedule and desired indoor temperature. This is a good pretentiousness to ensure HVAC systems are used and no-one else when necessary.
DDC Systems-For the large trailer building, I judge this as a must have system. Installation costs have steadily decreased and the pretend 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 exposure to air control. The best ration of these systems is their triumph to be scaled up to the largest of trailer applications. This means you can install a easy system and accumulate more controls forward-looking to incorporate your entire sum HVAC system. Again, the payback is hasty and without difficulty worth the investment.
Operation and Maintenance
The fourth and last step to attain vivaciousness and HVAC system optimization is operation and maintenance. The most efficient HVAC systems are without difficulty maintained. Ensure reliability, efficiency and a long vivaciousness for your HVAC system by when these tips.
Find a endorsed consultant you trust. If you are a home owner or little trailer building owner, locate a good HVAC company or mechanic to explore and maintain your system. If you are a large trailer building owner, locate a trailer HVAC company for normal maintenance. make sure you stamp album and document every servicing when dates, epoch and names of the servicing person.
Home owners should always acquire a seasonal tune up. The operation of your system will rework when the seasons of the year.
Replace your expose filters regularly. Don't use anything less subsequently a MERV 5 filter to assure dust and fibers are removed. clean filters will keep fan energy.
Coil Cleaning-This is always a big item overlooked by residential and trailer building owners. Condenser coils entire sum dirt and debris upon their surfaces because they are outside. This makes the compressor pretend harder and results in a forward-looking refrigerant temperature in your refrigeration system. Evaporator and heating coils entire sum dust and fibers that spread inside your home or building. clean them at least when a year
