When it comes to making design decisions, there are many factors to consider and innumerable scenarios for each project. While the ideal scenario must fit within the project budget, two related considerations are lifetime operating costs and energy use. With so many possibilities, how do we help our clients make the best decisions? A key tool we use at Cushing Terrell is energy modeling.

With energy models, we review potential building performance scenarios long before construction and afterward through our post-occupancy evaluation (POE) process. POEs give us the opportunity to make further refinements and upgrades as systems age or as new technology is developed. It’s also important to check our assumptions against the actual data to continually improve future comparisons.

What do we look at? We combine factors such as building orientation, weather patterns, construction materials, HVAC systems, and building-use predictions, among many others. Then we analyze the data and make adjustments to find the right balance between cost and energy-use options for each project. To get an idea of how it works, I describe three projects below, looking at what the energy models told us, the design decisions made related to energy use, and how the facilities are operating today.

NorthWestern Energy — Montana Headquarters | Butte, Montana

The five-story, 98,000 sq. ft. Montana headquarters for NorthWestern Energy was designed with a couple high-priority goals in mind: 1) create an attractive place for people to work, reflecting the company’s culture and 100-year history in the community, and 2) demonstrate a commitment to sustainable, energy-efficient operations. Awarded LEED Gold certification for new construction, the project included systems that utilize indoor evaporative cooling, heat recovery, an under-floor air-distribution system, energy-efficient lighting, and advanced lighting controls to maximize performance and reduce operating costs. Mosaic was the lead design firm, while Cushing Terrell provided mechanical, electrical, plumbing, and fire protection design services.

The energy analysis for this project focused on providing the right heating and cooling solutions for each type of space. Under-floor air-distribution systems give occupants control over their temperature and airflow patterns, providing individualized comfort. Excess heat, generated by spaces such as data rooms, is used to warm up cold ventilation air in the winter. Overall, the energy modeling efforts in this case were largely aimed at making decisions to optimize mechanical systems for both energy efficiency and occupant comfort.

What the data told us then

• Under-floor air-distribution systems reduce energy consumption by heating and cooling people instead of entire spaces.
• Heat recovery systems are key to reducing energy consumption during cold Montana winters.
• The building energy use intensity (EUI) was predicted to be 51.4 kBTU/sq. ft. per year.
• The building would reduce energy costs by about 20% over a minimally code-compliant building.

And what it tells us today

• Actual EUI is 49.3 kBTU/sq. ft. per year, 4.3% less than predicted.
• Actual data varies by month, mostly due to seasonal weather variations.
• Office spaces like this one have predictable usage patterns, which help energy modeling accuracy.
• Assumptions and mathematical models closely match reality.

Ada County — 911 Dispatch Center | Meridian, Idaho

For the 25,000 sq. ft. Ada County 911 Dispatch Center, our team designed a new facility for 911 dispatch as well as new electrical and mechanical systems to reduce energy consumption. The design solution needed to be energy-conscious and 21% below ASHRAE 90.1, while still meeting the needs of the emergency dispatch staff. Aspects of this project that were key to the design considerations were the heat-generating data center and building use as the dispatch center operates 24/7, 168 hours per week.

The team designed an in-row cooling system for the data center using a modulating chiller unit along with a modulating in-row fan system. The team also used variable refrigerant flow (VRF) for the administration portion of the building. The electrical system used for the dispatch and data center is redundant with a hot-swappable component so the system will not have to shut down for servicing or replacement of parts. Additionally, the high-tech workstations for dispatchers allow for individualized climate control in order to adjust heating and cooling as needed.

Early energy models explored all aspects of the building, including the thermal envelope, orientation, lighting, and HVAC systems. These models showed that the data center and HVAC systems had the greatest impact on performance. The energy modeling process led to the addition of the free-cooling chiller module that uses cold outdoor air to cool the data center without introducing outdoor contaminants. The energy model was then used to obtain utility incentives for the mechanical equipment, partially offsetting the additional costs of the more efficient equipment.

To wrap up

These three projects illustrate our process of identifying different variables and opportunities, implementing the best options based on the data at hand, and checking our assumptions following occupancy to see how the buildings are performing. Energy models allow us to identify solutions that meet our clients’ needs as well as show economic and energy impacts. Additionally, they help us procure funding opportunities, such as utility incentives, to decrease investment costs.

Investing in first public offerings (IPOs) could be an interesting experience for investors since companies moving from private to public could offer large rewards. Still, the IPO is a complicated process and time consuming too. Any investor wishing to participate must first grasp this process.

What Is An IPO?

IPO is the time when company offers its share for the very first time. By using this process, the company can generate funds for several projects, including debt relief, enhancement of operations, and financing of R&D. Once a firm goes public, IPOs allow investors to purchase shares at the greatest pricing and maybe benefit from company expansion.

The IPO Process

The IPO process consists of the following important phases:

· Pre-IPO Preparation

Making the IPO ready Before public release, an organization needs to be totally ready. This entails compiling a team of underwriters—often investment banks—doing financial audits and finishing regulatory paperwork. The company has to forward a registration statement detailing its activities, financial situation, and risks to the relevant stock market and regulatory agencies.

· Roadshow And Pricing

The management of the company starts a roadshow to introduce it to possible investors after the clearance of the registration statement. Demand and IPO interest are determined in great part by this stage. After the roadshow, the business and its underwriters will decide the final offer price, considering investor comments and market conditions.

· Subscription Period

Investors have access to shares for the whole subscription period of the IPO after pricing. Shares are held online using open demat account—also called a dematerialized account. Those who properly apply for the IPO will not be able to obtain their allocated shares in any other manner. Link your trading and Demat accounts to offer perfect investing conditions.

· Allotment And Listing

The allocation process kicks in when the subscription period is out. Usually, in cases when demand exceeds supply, retail investors split shares by lottery. The shares credit the Demat accounts of the investors after allocation. The shares begin trading on the stock exchange on listing day, therefore enabling investors to buy or sell them on the open market.

Trading And Post-IPO Considerations

Investors should check the stock after the IPO. Demand and market attitude will cause prices to change over the first several trading days. Investors should evaluate their investment plan depending on their financial goals and decide whether to hold for the long run or sell for fast gains.

Those considering an initial public offering (IPO) have to be aware of every stage of the process, from documentation to trading. Knowing what to expect could make handling the operation easier, even if it could be complicated generally. Recall that you need an open Demat account to retain and handle your shares so you may take part in initial public offers (IPOs). Knowing the IPO procedure will help you to make wise judgments and maybe seize the interesting opportunities the IPO sector offers.

We send messages, emails, and notes to friends, family, and coworkers daily. Sometimes, these messages contain private information, such as passwords, financial details, or personal secrets. Sending this kind of information through regular channels can be risky. Hackers, thieves, or even nosy people might try to read your private messages. One tool that can help with secure messaging is Privnote. What is privnote? You write your message on their website, and it creates a link. When someone opens that link and reads the note, it disappears forever. This way, your private information doesn’t stay where others might find it.

• Using encrypted messaging apps

Another way to send secure notes is through encrypted messaging apps. These apps scramble your messages so that only the person you’re sending to can read them. Some popular encrypted messaging apps include Signal and WhatsApp. When looking for a secure way to send notes, you should look for end-to-end encryption. Your message is encrypted and only decrypted on the receiver’s device. No one in between, not even the service company, can read your messages.

• Creating strong passwords

No matter what method you use to send private notes, having strong passwords is crucial. A strong password makes it much harder for hackers to guess or crack. Use a mix of upper and lowercase letters, numbers, and symbols.

• Two-factor authentication for added security

Many secure messaging services offer two-factor authentication. After entering your password, you’ll need to provide a second form of identification.

• Role of virtual private networks (VPNs)

A VPN can add another layer of security when sending private notes. It hides your internet activity from your internet service provider and potential hackers, making it harder for someone to intercept your messages as they travel across the internet.

• Secure file-sharing services

Sometimes, you need to send private documents, not just text messages. Secure file-sharing services can help with this. These services use encryption to protect your files as they’re uploaded, stored, and downloaded. Some even let you set passwords for individual files or set them to expire after a specific time.

• Regular software updates

Keeping your devices and apps up to date is essential for security. Software updates often include fixes for security flaws and closing potential entry points for hackers.

• Being careful with email

Email is not the most secure way to send private information. Emails can be intercepted or forwarded to others without your knowledge. If you must send sensitive information by email, consider encrypting the message or using a secure email service.

• Importance of digital hygiene

Good digital hygiene habits help keep your private notes secure. This includes not reusing passwords, logging out of accounts when you’re done, and being careful about what information you share online.

Consider how sensitive the information is and choose a technique that provides appropriate security without being too difficult to use. what is privnote, Sending private notes securely in our digital world is possible but requires some thought and care. Remember to use strong passwords, be cautious on public Wi-Fi, and keep your software updated. With these practices, you can communicate privately and securely in the digital age.
