「英中对照」聚焦老旧建筑改造：Reliable Controls以楼宇自动化为老旧建筑注入新生

Why retrofitting matters

According to the Canadian Green Building Strategy, most buildings that exist today will still be standing decades from now. And the United Nations reports that only half of all buildings that will exist by 2050 have been built. That means retrofitting existing structures is just as important as designing new ones—especially when it comes to energy efficiency, comfort, and sustainability.

For building owners, facility managers, and consultants, building automation is one of the most powerful tools available when updating older facilities. Whether you need to improve indoor air quality, reduce operating costs, decrease your carbon footprint, or enhance tenant comfort, building automation delivers significant value without the environmental or financial burden of new construction.

The business case

Energy-efficient retrofits can dramatically lower utility bills and maintenance costs while improving occupant comfort and overall building resiliency. The numbers speak for themselves: In one report from the Pembina Institute, comprehensive retrofits to windows, HVAC, and automation systems were shown to cut energy use by up to 90 percent and carbon emissions by up to 99 percent.

Retrofits are also cost-effective compared to rebuilding or new construction. Efficiency Canada cites research from UBC that shows energy retrofits cost about two-thirds the price of a new build.

Utility companies and governments are also stepping up with rebates and tax incentives. In the US and Canada, various federal and regional programs reward building owners for upgrading outdated systems to high-efficiency HVAC equipment, renewable energy sources like solar power, and automation platforms that support energy tracking and demand-based use.

How Reliable Controls building automation helps

Reliable Controls building automation systems are designed to support sustainable retrofits at every scale. Using BACnet open protocol, the company’s technology integrates seamlessly with older equipment and evolving energy strategies, meaning your retrofit solution is tailor-made to your exact building layout, equipment configuration, and specific HVAC and automation needs.

A Reliable Controls retrofit can provide:

• Real-time data and remote visibility for better day-to-day decision-making
• Enhanced indoor air quality through responsive ventilation, temperature control, and unit sequencing
• Long-term system reliability and operational safety
• Improved cybersecurity by replacing outdated automation system hardware and unsupported control software

Reliable Controls solutions are engineered for longevity, flexibility, and open integration, helping clients extend the life of their mechanical systems while building toward low-carbon operations.

A retrofit in action

What does a retrofit success look like?

In Oakland, California, the StopWaste agency administration building helps Alameda County businesses, residents, and schools waste less, recycle properly, and use water, energy, and other resources efficiently. 

With a Reliable Controls system at the core of a recent building retrofit, StopWaste streamlined its heat pump sequencing while improving temperature control and reducing the overall operation time. Additionally, wall-mounted SMART-Sensor EPD devices now report real-time room data like CO₂ levels, temperature, and occupancy. These sensors connect to legacy Reliable Controls MACH1 and MACH2 controllers and a newly installed MACH-ProZone controller, thanks to built-in backward compatibility and open protocol networking. 

The retrofit also needed to integrate new technology in a way that helped the StopWaste facility maintain its LEED Platinum status and facility requirements while unifying its HVAC systems with a scalable solution.

Other Reliable Controls retrofit success stories include 201 California Street, an 18-story high rise in the heart of San Francisco; the historic West Block government building in Canberra, Australia; and the 1.6-million-square-foot M&T Bank Stadium in Baltimore, Maryland. 

These projects show how Reliable Controls solutions have helped modernize existing facilities, improving performance while supporting occupant needs and sustainability goals.

Steps to a successful retrofit

No two retrofits are the same, but the best outcomes share a common path:

1. Start with an assessment. Evaluate current system performance and identify energy or control gaps.
2. Pinpoint high-impact upgrades. Focus on HVAC, lighting, controls, and key system issues with measurable ROI.
3. Choose the right partner. A flexible building automation system installed by a skilled Authorized Dealer can make all the difference between a quick fix and a long-term solution.
4. Design with scalability in mind. Ensure your system can evolve with future operational needs and sustainability targets.

The key is to take a whole-building approach. Retrofitting in isolation leads to inefficiencies, but an integrated building automation solution allows your systems to work together, enabling measurable, efficient energy use and smoother facility management.

The payoff

When done right, building retrofits lead to happier occupants, lower bills, and buildings that are easier to manage and maintain. Operational staff gain access to data they can act on, while building owners benefit from reduced downtime, streamlined maintenance, and long-term savings.

On a global scale, retrofitting helps move cities and countries toward their climate targets without the increased carbon emissions found in new construction. By breathing new life into older buildings, we reduce our environmental footprint while creating healthier, more resilient spaces for the people who use them every day.
