Let the natural light in and keep the elements out, all while saving energy and money. Find out how commercial building windows play a critical role in improving tenant comfort, reducing energy consumption, and cutting costs.
Secondary Windows Rejuvenate 1970s Office Building
Built in 1975, Hurley Development’s 915 Broadway office building in downtown Vancouver, Wash., features floor-to-ceiling windows in every perimeter office—6,000 sq. ft. of windows in total. While all of these single-pane windows let in a vast amount of natural light, they also brought in far too much heat in summer, and too much cold air in winter. This thermal leakage not only led to tenant comfort complaints, it also inflated energy costs by forcing the aging HVAC equipment to strain to maintain indoor temperatures.Case Studies
High-Performance Windows at a Fraction of the Cost
Secondary windows—also known as low-e storm windows, insulating panels, or secondary glazing systems—are a cost-effective, high-performance alternative to full window replacement for commercial buildings with old, inefficient windows. Secondary windows simply attach to the interior or exterior of an existing (i.e., primary) window for quick installation, resulting in improved occupant comfort, health and wellness, while reducing heating and cooling energy use by up to 20 percent. Further, secondary windows can achieve about the same performance as replacing windows with new high-performance models, but for as little as half the cost.Resources
Secondary Windows Help Lead the Way to LEED Certification
In an effort to maintain the aesthetically pleasing and historically important appearance of the building’s façade, Montana State University turned to secondary windows to easily and more cost-effectively increase the building's energy efficiency and occupant comfort.
Secondary Windows Bring Stellar Savings for Aerospace Firm
Crane Aerospace and Electronics is an aerospace components manufacturer in Lynnwood, Wash. After receiving thermal comfort complaints in the summer and winter from occupants of a second-story office building, Crane committed to replacing the inoperable single-pane windows throughout the building with energy-efficient secondary windows.
Secondary Window Inserts Perform Flawlessly at Carnegie Hall
One of only four Carnegie Halls still in continuous use as a performance space, the Carnegie Hall in Lewisburg, W. Va., has hosted a wide variety of performers and artists since its opening in 1902. While the building's meticulous preservation has kept it as beautiful and impressive as it was more than a century ago, the building’s historic nature has led to increasingly higher energy bills every year...
400 Market Street
400 Market Street is a 12-story, 200,000-square-foot office building owned by Kaiserman Company. The building, built in 1972, had already undergone several building energy performance upgrades, but its poor performing single-pane windows were a weak point. The property manager wanted to improve tenant comfort, reduce operating expenses, and improve the building’s ENERGY STAR® rating, while avoiding the costly and lengthy process of full window replacements.
Advanced lighting starts with control. Discover how commercial building lighting design and modern technologies can combine to affect your budget, market differentiation, aesthetics, and tenant comfort.
LLLC: The Future of Efficient Lighting
Luminaire Level Lighting Controls (LLLC) take energy efficient LEDs to the next level by applying control. With lighting control, owners and managers can tailor lighting systems to maximize energy use, optimize tenant comfort, and integrate additional building energy efficient systems for overall improved operational performance.
Better comfort and energy costs start with the right HVAC. Understand how heating, cooling and airflow all directly contribute to the energy efficiency and tenant comfort of your commercial building.
From HVAC and lighting controls to secondary windows, there are many solutions for an efficient commercial building. Knowing how to integrate those solutions so they work together in an energy-efficient system may mean saving time and money. Whether it’s a retrofit or new commercial project, learn how to apply an integrated design.
