Portland law office objects to inefficient HVAC
When SBH Legal moved into a nearly century-old historic building in downtown Portland, Ore., they knew that a variety of improvements would be necessary to modernize building efficiency and provide a comfortable indoor environment for their employees and clients. By embracing an optimized approach to a dedicated outside air system (DOAS), SBH Legal drastically reduced their building’s overall energy use by 60%, while improving the indoor air quality (IAQ) and occupant thermal comfort.
Road noise disturbs the peace at Portland law firm
When Portland law firm SBH Legal purchased their 1925 office building, they immediately noticed the road noise. While a full window replacement would be disruptive and cost-prohibitive for SBH Legal, they discovered a cost-effective, easy-to-install alternative called secondary windows.
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.
Portland firm engineers thermal comfort and HVAC efficiency
Originally built as a warehouse in 1943, the 11 Main Building in Portland, Oregon, was converted into an office space in 2014. Though its existing HVAC system was functional, its deficiencies created an uncomfortable indoor environment with occasionally poor indoor air quality. Learn how Energy 350 upgraded their HVAC using the very high efficiency DOAS approach to improve their comfort and air quality while saving energy and money.
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.
Class-A office building finds grade-A booster pump solution
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.
South Lander Business Park adopts luminaire level lighting controls
Seattle’s South Lander Business Park needed to upgrade its outdated fluorescent lighting across a diverse range of retail spaces. Learn how they worked with their utility to get incentives.
Research firm engineers a smaller energy footprint
Ecotope, an energy efficiency engineering and research firm in downtown Seattle, outgrew their office space and decided to lease the third floor of a 3.5-story mixed-use building. The building’s existing heating and cooling equipment featured an all-electric, variable air volume (VAV) rooftop unit (RTU) with electric resistance terminal heat in the individual zones including open office areas, conference rooms, a shared breakroom and a server room.
Legal firm objects to older building’s inefficiencies and discomfort
Local law firm Immix Group purchased the upper floor of a 1909, two-story historic building in the once-industrial area of Northwest Portland. Vacant for nearly three years, the 12,000-square-foot space presented many comfort challenges. Air leaked between floors, the fresh air dampers were all closed shut, and the oversized existing HVAC system was aging and inefficient.
