A mission-critical system is a system that is essential to the operation of a business or organization. When a mission-critical system fails or is interrupted, it significantly affects business operations.


An example of a mission critical system is an HVAC system. If the heating or cooling system goes out, most commercial properties or agencies such as retail centers, hospitals, or educational facilities would no longer operate.


Therefore, your building needs an HVAC system that is well-designed, energy-efficient, and dependable. LKPB mechanical engineers evaluate and design HVAC systems and control features to leverage the system in any commercial building.

Reducing HVAC Energy Use

As energy regulations and incentives continue to put efficiency on the forefront, your primary concern may be finding an innovative solution for redesigning your HVAC system


The first step in reducing HVAC energy use is reducing heating and cooling load. This is the amount of heat that needs to be added or removed from your building. There are multiple strategies that we may help you employ to accomplish such as:


●        Reducing heat from internal equipment and lighting

●        Minimizing unnecessary ventilation

●        Designing a tight insulated building envelope

●        Using high-performance windows

●        Taking advantage of the building’s thermal mass to store and release heat later


One way we can accomplish these objectives is through building energy modeling (BEM). By utilizing energy modeling, we can predict how you’re HVAC design will perform within your building before installing it. Since the HVAC is a mission-critical system, it is imperative that we get the design right the first time.


BEM allows us to create an accurate virtual that forecasts various aspects of the system such as energy consumption, air distribution, longevity, and any weaknesses in the system that we need to analyze and adjust. It also provides insight on what type of heating or cooling system works best in your building.

Load Calculations

HVAC load calculations require time and attention to detail Calculations are based on the square footage of the conditioned floor area. In most buildings, you need 400 to 600 feet per ton of conditioning capacity. The reason the calculation is important is that it determines the size of the HVAC system as well as how it is designed and channeled through your building.


The overarching objecting in HVAC design outside of efficiency is proper balance and distribution of the air into every room or area. Therefore, the unit has to be the right size. If the main unit is too large or too small, both performance and efficiency are compromised.


Since the HVAC system is a mission critical system, it needs to operate efficiently at all times. Otherwise, the parts will break down faster, it will not distribute air as it should, and you’ll spend more money on operating costs and repairs.

The Need for Sustainability

Today, the needs of building owners and managers have evolved. Energy efficiency used to be regarded as the most important issue on the table. And although efficiency is still a vital aspect of any HVAC system, we are now finding that sustainability is equally important in a system as mission-critical as a heating or cooling system.


Therefore, the system must be long-lasting, made of sustainable materials, reduce carbon emissions, and provide an option for retrofitting instead of a full system replacement down the road. How we design the system today, will affect all of these issues sooner or later
