As we build back from the pandemic, the building industry is rethinking how we approach health in commercial spaces. With sensors in every fixture, LLLC systems save significant energy (on average up to 63%) and also offer buildings a distributed mesh-network throughout a space. This has the potential to revolutionize how we monitor and respond to environmental factors that impact human health. Learn how LLLC could be used in countless ways to improve health and efficiency.
Understanding how to teach clients about advanced lighting solutions can be just as important as understanding the technology itself. Find out how GEL Energy Solutions leveled up their lighting knowledge with NXT Level Lighting Training.
Lighting technology is changing all the time. That's why more and more professionals are looking for advanced training from programs like NXT Level Lighting Training. Find out what DMA Lighting took away from their training and how they passed the knowledge on to their customers.
Secondary windows—also known as interior 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 reduce heating and cooling energy use by up to 20 percent and cost 30 to 50 percent less than window replacement (depending on the product and application).
Peer into the ‘Eyes’ of the Building: When it comes to energy efficiency, your building envelope will have the greatest impact due to it having the longest live components and a greater impact on heating and cooling loads. Watch as Mike Hatten, P.E. and Owner of Solarc Energy Group explains how your biggest problem and also your solution, is windows. The why of energy efficiency is easy, we’ll show you how.
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.
Built in 1909, Newcomer Hall at the Maryland School for the Blind in Baltimore, Md., is a private, nonprofit, state-supported institution attended by 73 percent of Maryland’s 1,800 blind or visually impaired students, age 3 to 20. The brick building provides space for early learning and elementary, middle, and high school programs. Due to its age, the building required a major restoration project that completely renovated the interior...
Dedicated outside air systems (DOAS) separate heating and cooling from the ventilation system to allow for optimal control of each of these critical building functions. Building on the DOAS concept, a very high efficiency DOAS includes heat recovery ventilation and focuses on increased equipment efficiency and optimized system design. When compared to a code-minimum system upgrade, very high efficiency DOAS can reduce commercial building energy use by an average of 36%, and HVAC energy use by an average of 65%.
C-RTU installation is very similar to the installation of conventional gas rooftop units (RTUs). However, C-RTUs require careful attention to condensate management, including specific approaches to piping, pumps, neutralizers, and freeze prevention. This guide references code requirements, manufacturer instructions and practical experience to provides tips and best practices for installing C-RTUs.
This guide outlines best practices for the proper installation of condensing rooftop units (C-RTUs). These recommendations are based on a comprehensive field study conducted during the 2018/2019 heating season, in combination with a literature review of state and national code requirements and manufacturer guidelines.
Condensing rooftop units (C-RTUs) have recently entered the commercial RTU market, providing the benefits of non-condensing RTUs at much higher efficiency levels and lower operating costs. In fact, condensing furnaces can achieve over 90 percent AFUE—a big upgrade when compared to traditional gas furnaces that range between 78- and 82-percent AFUE.
