Commercial buildings are reliant on various systems to operate correctly, including lighting fixtures, air-handling units, compressors boilers and pumps.
In order to prevent issues such as decreased performance, higher operating and maintenance costs, and risky conditions for occupants from occurring in existing buildings over time due to a decrease of compliance with building codes below minimum standards established by applicable codes.
The best way is to ensure code compliance before construction or renovation begins on the facility.
Assessing building systems even if they are currently running well can help you identify areas of opportunity for improving performance.
The old adage “if it ain’t broke, don’t fix it” doesn’t apply here because technology is constantly evolving and will always present opportunities to enhance the properties we manage.
Lighting installations are among the most important systems in commercial buildings, as they allow for both human safety and successful business transactions.
Common light issues that diminish productivity and compromise safety, requiring the attention of an engineer are:
No matter what problems you encounter with your lighting system, it is best to let a professional do the troubleshooting. Sometimes many factors interact and form relationships that aren’t obvious at first glance.
If you want to upgrade your lighting system and would like their input, don’t hesitate to contact a professional. In general, there are three types of improvements you can carry out:
You should consider replacing the faulty light fixtures with LED lights because they can be controlled remotely by a smartphone app and have longer lifespans than traditional bulbs. If this installation is upgraded with integral LED troffers controlled by occupancy sensors, all available benefits can be achieved simultaneously:
HVAC installations are among the largest and most complex systems in commercial buildings. Their main purpose is to keep temperature and moisture within a range that is comfortable for humans, while constantly renewing the air inside; therefore, malfunctioning HVAC systems not only cause discomfort but also degrade indoor air quality and may bring health issues.
If any of the following conditions are found in a commercial building, getting in touch with an HVAC engineer or consulting company is recommended:
A broad range of HVAC system upgrades exist, but this can lead to confusion about which is best. Consulting services will help you determine what works for your building. The following are some common options:
An example of a system-level HVAC upgrade would be to replace an old four-pipe installation with a variable refrigerant flow (VRF) or water-source heat pump system.
HVAC systems are the largest energy expense in a commercial building, sometimes even more expensive than all other expenses combined.
Because of this, upgrades that improve HVAC performance have great financial value and so tend to be very attractive from an economic standpoint.
Like most high-rise commercial buildings, the building I work in uses a pumping system for water instead of relying on local utility pressure. This is because even though there’s enough pressure coming from our pipes and valves to supply us with running water at all times – we can’t access it if it isn’t constantly flowing out of the faucets or sprinklers due to gravity pulling down towards earth.
To tackle this problem that doesn’t cause any inconvenience, my company has installed pumps which are also essential for fire suppression systems as well as HVAC cooling towers where they use warm wastewater pumped through chillers.
To reduce the negative effects of water hammer and cavitation, on pumping system components it is important to control them. If they are not controlled, equipment life expectancy will be decreased drastically.
If pumping system components fail frequently in a commercial building, the installation should be assessed by a qualified professional.
Energy-saving opportunities exist in pumping systems, just like lighting and HVAC installations. The following are some commonly suggested measures:
Although pumps generally consume less energy than HVAC systems, they contribute to a significant expense nonetheless. Also consider that pumping and HVAC systems often work together for example in AC systems where water-cooled chillers or water source heat pumps are used.
Upgrading the two simultaneously can create synergy if both have been upgraded at once.
When a commercial building is losing money on energy costs, improving individual systems can help. However, to achieve the best result it’s necessary to upgrade the entire system of which these parts are part of.
In order for this to happen there are three main areas that need attention from an engineering professional or company: envelope insulation and windows; HVAC equipment efficiency; lighting quality and quantity control.
The building envelope should accomplish three main functions:
Building envelope upgrades can improve performance in three ways, but they are expensive. However, these measures pay for themselves when implemented during construction or renovation because the savings on utility bills make up for their costs over time.
On-site generation with renewable energy systems can be an attractive option because it is more environmentally friendly than traditional power plants.
The technologies with the most potential in commercial buildings are the following:
Solar power could be a great investment because not only is it free and renewable, but there are also tax incentives in place to make up for the lack of sunlight. Furthermore, electricity rates tend to be high so solar power would save you money.
Energy-efficient appliances reduce total energy consumption, while renewable energy systems allow buildings to generate their own power. This can be complemented with building management systems (BMS), which intelligently consume electricity when the cost is lowest and cause occupants no discomfort or inconvenience.
Key Takeaway: A commercial building can improve its performance significantly with an assessment by qualified engineers. It is possible to detect and fix issues affecting the existing installations, while finding areas of opportunity to save energy or improve comfort.
The best results are achieved when building systems are addressed simultaneously since it’s possible that interactions among them could be detected as well as opportunities for synergy found.
