When Urban Renaissance Group purchased Tower 333, a 20-story office building in Bellevue, Wash., they knew the aging and inefficient water-booster system needed to be replaced. The original system consisted of three 20-horsepower constant-speed booster pumps operated in a staged sequence, bringing on successive pumps as demand changed. With a commitment to occupant comfort and maintaining the building's energy-efficiency certifications, the company knew they had to find a replacement for the aging water-booster system that would save energy and improve performance.
Building renewal is centered on an investment strategy that delivers ongoing value to its stakeholders: owners, tenants, investors, and society. Meeting these objectives can be measured in many ways: net operating income, avoided future risk, tenant attraction/retention, achieving environmental and social governance (ESG) reporting targets, and ultimately delivering a healthy, productive, environment for building users.
Whether your goal is to position your building for long-term, energy-efficient, high-value operations, or to meet a demanding energy performance standard, we all know that no project comes off without a hitch. All projects risk not meeting important milestones, cost overruns, and extended timelines, or something worse if planning doesn’t include a strategy for the “what ifs.”
Building renewal is a process of planning and implementing integrated solutions that maximize energy performance and building value over time. It is a comprehensive lifecycle approach that identifies areas for energy efficiency improvements, financial planning and investment strategies, building and system upgrades and retrofits, and the ongoing operations and maintenance of a commercial property. It helps deliver maximum value and market position by saving energy and reducing operational costs, complying with standards, and future-proofing your building to avoid regulatory risks. Additionally, it enables a healthy and productive indoor environment that can help mitigate risk in an uncertain market.
Very high efficiency dedicated outdoor air systems (very high efficiency DOAS) are a proven solution for reducing energy consumption as they optimize the control and functionality of ventilation and thermal comfort independently.
This comprehensive design guide includes the system definition and design recommendations that provide guidance to manufacturers, designers and specifiers regarding the key components of a Very High Efficiency Dedicated Outside Air System.
Electric motors meeting the NEMA Premium standard are now the starting point for many pumps, fans, and other motor-driven systems being sold today. Even greater efficiency is available with electrically commutated motors, synchronous motors, and other cutting-edge motor technologies.
Dedicated outdoor air systems (DOAS) are a proven solution for reducing energy consumption as they optimize the control and functionality of ventilation and thermal comfort independently. A very high efficiency approach to DOAS pairs a high efficiency heat/energy recovery ventilator (HRV/ERV) with a high efficiency heat pump, while following design principles that optimize performance.
Healthy air quality in buildings improves cognitive function and combats the spread of disease, but its implications for carbon reduction are perhaps the most important benefit.
Dr. Julia Day’s vision for her work is guided by a straightforward equation: healthy people plus healthy buildings equal a healthy planet.
Path to Zero: Taking steps toward creating experiences that reduce energy use and improve the overall experience of the building. Andrew Lee, Director of Zero Energy at the International Living Future Institute, describes how having a clear path to zero results in better buildings that draw attention to you, your tenants and future talent. The why of energy efficiency is easy, we’ll show you how.
