Retrofit Model for Commercial Buildings


New York City’s Empire State Building will shine brighter than ever as it becomes an energy retrofit model for other commercial buildings.


The energy efficiency retrofit project began in 2009 as part of the Clinton Global Initiative, and has reduced utility costs for tenants and building owners by millions of dollars.


“The project team that has designed and conducted the retrofit over the Empire State Building’s 2.85 million square feet is rolling the same model out in nearly 100 major commercial buildings across the U.S., targeting 75% of energy use in urban settings that comes from commercial buildings.”


The building retrofit model focuses on eight improvement areas, with upgrades for windows, LED lighting, and management system controls. It is now being applied to large commercial buildings across the U.S.


And since buildings consume 40% of all energy in the country, this new retrofit model could prove to be a turning point to a clean energy economy.

Free Building Energy Tools Gain Ground

Energy benchmarking is becoming a must for large cities, with Boston being the latest one. Benchmarking mandates the measurement and disclosure of energy use for large buildings, and is meant to help building owners understand their energy use better, and to take action in poorly performing buildings.

In an effort to inspire action, the Lawrence Berkeley National Lab is developing tools to help inspire action. The most recent being EnergyIQ, which allows commercial users to benchmark their buildings and identify efficiency opportunities.

Using EnergyIQ, owners or managers “pick their parameters of a peer group across 62 different building types, including geography, size, vintage and operating hours.”

Other free or low-cost tools are also being developed for energy benchmarking including Noseis, Energy Deck, and Honest Buildings. Currently, Portfolio Manager is the primary benchmarking tool to meet the requirements set forth by local governments.

Energy Benchmarking Comes to the Midwest

Energy benchmarking commercial buildings

Energy benchmarking presents an opportunity for property managers to identify areas for increased efficiency and reducing operating costs.

Energy benchmarking is making its way to the Midwest in 2014 when Minneapolis will be the first Midwest city to require large commercial buildings to report their energy and water use annually.

Energy benchmarking presents an opportunity for building owners and property managers to identify areas for improvement to increase energy efficiency and reduce operating costs.

Though there are different ways to benchmark, most laws will allow cities to gather better data on a sector that usually consumes the bulk of overall energy. This type of transparency is the first step in monetizing efficiency and increasing the value of retrofits.

Energy benchmarking laws are fairly standard in much of Western Europe, but have just gained steam in the U.S. in recent years. Cities that have recently passed energy benchmarking laws include New York, Seattle, San Francisco,  Washington D.C., Philadelphia, Austin and California.

The aggressive promotion of efficiency programs could cut $169 billion a year from the energy bills of U.S. businesses by 2030.

According to a recent report, the aggressive promotion of efficiency programs could cut $169 billion a year from the utility bills of U.S. businesses by 2030.

The Alliance Commission on National Energy Efficiency Policy found that the U.S. could double its productivity, which in turn would create thousands of jobs and save homeowners and businesses billions of dollars in annual utility costs.

“Stopping energy waste will help all Americans get the most out of their hard-earned income,” said Kateri Callahan, president of the Alliance to Save Energy.

Lighting Retrofit Improves Hospitals’ Bottom Line

On average, lighting costs are 16 percent of hospitals total energy consumption, composing more than 40 percent of a hospitals electricity usage.

Large energy users, including hospitals, are seeing the benefits of lighting retrofits in their bottom lines. On average, lighting costs are 16 percent of hospitals’ total energy consumption; composing more than 40 percent of a hospital’s electricity usage.

“Two cost-saving techniques that hospital executives utilize are LED lights and harvesting natural light. In addition, linear fluorescent lighting is growing in demand in hospital energy improvement.”

Lighting retrofit projects can reduce a significant amount of kilowatts that are used, and the savings are significant especially in large energy users. Most lighting retrofit projects can be accomplished quickly depending on the size of the building, but you can also expect a quick payback.

“Small, energy efficient improvements can go a long way such as advancing lighting fixtures so that less wattage achieves the same brightness. Considering the thousands of fixtures that a hospital consists of, little efforts such as these can carry forth immense cost-saving benefits.”

Lighting Control Systems Key Tool for Efficient Commercial Lighting

Each month, Worldwide Energy Vice President and COO Gaylen Davenport will publish his thoughts on the latest energy-efficient news, products, and trends.

At Worldwide Energy, we are always looking for the latest technology to help clients reduce their energy use. Lighting controls are the next step in energy efficiency, especially with systems such as Encelium.

Encelium Energy Management System is an integrated lighting control and energy management system that dynamically responds to the changing characteristics of a building by providing the right amount of light, when and where it is required. It also allows monitoring, controlling, and scheduling from a computer, either onsite or remotely, to allow users to reduce energy usage.

Based in New Jersey, Encelium is a network-based program that interconnects electronic dimming ballasts, photo and occupancy sensors, and lighting fixtures to one central system. Devices communicate through low-voltage, two-wire hardware which eliminates the need for external power supplies and power packs for devices such as occupancy sensors.

The system features energy management software that is used to commission, configure, and manage the Encelium technology. The Polaris 3D software displays a variety of graphics to analyze and update a facility’s lighting requirements and track its usage. Facility managers can also instantly rearrange lighting layouts from one convenient interface.

Lighting control systems are catching on. In fact, a recent Pike Research study projected that the global market for intelligent lighting controls will expand from $1.5 billion in 2012 to more than $4.3 billion in 2020.

This innovative product, along with other lighting control technology, takes energy efficiency to a new level.

Common Misconceptions about Lighting Retrofits

Business owners are beginning to see the benefits of retrofitting their lighting systems to more efficient ones.

The lighting retrofit industry is quickly evolving, improving, and gaining traction. Business owners are beginning to see the benefits of upgrading their lighting systems to more efficient ones.

And while you plan for energy efficient solutions next year, there are still some misconceptions among those who are unfamiliar with products and the technological advances that have been made in recent years.

Three of the most common misconceptions about lighting retrofits are:

Misconception #1: Existing light levels are what they should be

The truth: existing lighting levels may be what employees are used to but very rarely are they what the light levels need to be. In fact, adjusting to higher lighting levels can help boost productivity.

Misconception #2: Light levels should be even throughout an entire facility

The truth: typically when a building is designed, the same light fixtures are installed throughout the building. In reality, light levels should be adjusted for the type of activity being performed in specific areas throughout the facility.

But lighting levels are not the only factor; usage plays a big role as well. For example, one side of the building, such as an office area, may be used more often than the other side of the building, such as a warehouse or storage area. Motion detection or sensors on lights are a great way to reduce the usage and levels of lighting in a facility.

Misconception #3: Existing lighting fixtures need to be replaced

The truth: With emerging technology, there’s virtually a retrofit for every existing fluorescent fixture out there. Retrofitting lights to a more efficient option is relatively low cost in terms of materials, labor, and disposal.

In some cases, replacing old lighting fixtures is the best way to save on utility usage and costs.

Rebates Drive Lighting Retrofits

Rebates and tax incentives helped this Kansas City warehouse update their lighting to save on costs and monthly utilities.

Light emitting diodes (LEDs) are more prevalent in lighting retrofits, especially as many companies are looking to their utilities to provide rebates. The rebates offer a large energy savings that takes reduces upfront costs.

“Utilities across the country show limited prescriptive rebate support for LED lighting,” found a report by Groom Energy and GTM research. And the number keeps growing.

In fact, four years ago, there was about $3.1 billion in total U.S. rebate dollars. And the numbers are expected to more than double in coming years, from $7.4 billion to $12.4 billion available in 2020.

There’s no coincidence that the LED market is growing as well. LEDs are one of the fastest growing light replacements to traditional fluorescent lights and offer a higher energy efficiency. It’s no wonder that the increased utility funds will help push LEDs into the commercial and industrial mainstream.
