The last two decades have introduced new considerations to building owners and developers when planning updates to existing commercial structures or investing in new construction. When accounting for the total cost of ownership and the potential return on investment, owners and developers should consider total energy usage, the lifespan of building systems equipment, the recruitment and retention of occupants, and lease rates.

1. Energy usage and efficiency
According to the U.S. Environmental Protection Agency, the average commercial building wastes 30% of the energy it consumes. This loss is due to equipment use when it isnāt neededāsuch as lights being left on in empty portions of the buildingāand outdated technology that consumes more energy than newer models.
In cold climates, temperature control accounts for a majority of the electricity use in commercial buildings. Traditionally, commercial HVAC systems achieve temperature equilibrium by balancing the amount of cold and hot air individually pumped into the building. Also problematic are HVAC systems that require heating and cooling throughout the entire building regardless of occupancy levels.
Todayās technology has produced systems that address both of these issues. Unlike comparable unitary equipment, variable refrigerant flow (VRF) technology provides different speeds of energy flow, rather than a traditional on/off feature, so that the optimal temperature is achieved more efficiently. Studies show that VRF systems decrease energy use anywhere between 15% and 42% compared to traditional HVAC systems. Similarly, a Minnesota state field study on VRF reported 30-40% reduced energy usage during the cold weather months.
Advancements in VRF technology have also substantially improved the reliability and precision of these systems. For instance, Mitsubishi Electric VRF systems are capable of producing simultaneous cooling and heating rather than each individually. This eliminates fluctuating around the optimal temperature by heating, then cooling, then heating again when using traditional units.
The Internet of Things (IoT) allows for the integration of occupancy sensors so electrical systemsāincluding lighting, HVAC, elevators and escalatorsāare only used as needed. These systems provide real-time feedback on electricity use, and some are capable of predicting occupant habits. According to the Building Owners and Managers Association (BOMA), replacing products that are 10 years old or older has a tremendous impact on the energy use of the system due to the changes in technology within the last decade.

2. Lifespan of equipment
In the past, building owners could expect their systemsāsuch as HVAC unitsāto last 15+ years with little upkeep. Todayās technology is more sophisticated, with more moving parts. While older systems may deal with neglect, such as dirty air filters and blower wheels, expecting the same from a new unit can decrease its life expectancy and increase the likelihood of downtime. Scheduled maintenance before a problem occurs helps with the upkeep of units and product lifetime expectancy.
The advantages of investing in products whose manufacturers provide regularly scheduled maintenance are three-fold: products will last longer, decreasing the need for replacement within 20 to 30 years; increased tenant retention and satisfaction by minimizing instances of system downtime; and increased value of the building in the instance that you want to sell.

3. Tenant recruitment and retention
The recruitment and retention of tenants and employees has become a priority in todayās commercial real estate market. With an increase in optionsādue to low unemployment rates, flexibility in where employees are able to work, and an abundance of available office spacesāthe stakes have been raised for building owners and developers. Retention, in particular, is a hot-button topic for building owners as they consider the total cost of loosing a key tenantāfrom lost monthly income, to the space fitout and upgrade costs, to recruitment and advertising expenses.
For tenant-paid utilities, showing a decrease in energy cost due to energy-efficient systems and appliances can have a positive effect on tenant recruitment and retention. Even if the energy saved doesnāt make up for additional costs, tenants are more apt to lease spaces where the owner is energy-conscious.
There is also the reliability of the building systems: Frequent downtime of units can cause frustration among building occupants and lost revenue and productivity for tenants. An hour without power can cost companies more than $100,000 in revenue. Investment in products from Mitsubishi Electric can help reduce such risks and provide better quality and greater efficiency.

4. Lease rates
Installing the latest building systems in a new or renovated building will provide immediate ROI in the form of increased lease rates. When negotiating, tenants are more likely to accept a higher lease rate if it means they have updated equipment, especially if they will be saving money through less expensive operating costs.
Although the trend shows leases are getting shorter, tenants want to avoid the costly, stressful, and time-consuming moving process as much as possible. Therefore, they are more likely to sign or re-sign a lease if they havenāt experienced any negativesāsuch as repetitive elevator downtimeāand the system cost savings show up on their monthly bills.
The times are changing, but that isnāt a negative. Todayās building systems work harder, smarter, and with less energy than ever before. Considering the long-term profitability of your building can set you up for success.
