Fort Collins Senior Center Expansion and Renovation Complete

July 11, 2014- Construction at the City of Fort Collins Senior Center wrapped this month with a grand opening celebration revealing results of a construction project that “has ushered the center into a new era and allowed it to evolve with the city’s growing senior population,” reports local news agency, The Coloradoan.

Alpen 525 Series windows are prominently featured on the new expansion and renovated building façade. Designers selected large Alpen picture windows fitted with 2″ simulated divided light grids to mimic the look of the previous outdated windows while updating the look of the new building with clean, modern lines. In addition to maximizing energy efficiency by increasing the amount of uninterrupted high R-value glass area, simulated divided light grids also drive down window cost by reducing the number of individual mulled or joined window sets.

Blending high quality design with efficiency and longevity, the new Alpen windows fit perfectly with the Senior Center’s forward-thinking vision and mission.

ACTION-Housing Passive House multifamily project wins Innovation Award, selects Alpen windows

In April, 2014, Alpen HPP shipped the first installment of windows to Uptown Lofts in Pittsburgh, PA, ACTION-Housing’s first Passive House-designed affordable, low-income multifamily apartment building.  ACTION-Housing received the Pennsylvania Housing Finance Agency’s first Innovation in Design Award in May 2013.

Alpen HPP is proud to have been selected by ACTION-Housing, FortyEighty Architecture, and Passive House Consultants Kaplan Thompson Architects to provide our 525-S Series fiberglass windows in this precedent-setting Passive House multifamily urban infill project.

Read more about this exciting project online and check back on AlpenHPP.com for project photos as installation progresses this summer.

Nelson Jones, D.  “Housing project in Pittsburgh’s Uptown emphasizes energy efficiency.” Pittsburgh Post-Gazette.  12 January 2014:

“Two buildings under construction in Uptown will provide 47 new apartments — 23 affordable units in one and 24 units for young adults moving out of foster care in the other.

But the $12 million project by Action Housing will provide more than housing. Each will be three stories and 30,000 square feet but built to different standards so Action Housing can determine the long-term value of passive energy design in one compared to current energy code standards in the other.”

ACTION-Housing, Inc. “News and Events: ACTION-Housing Wins Innovation in Design Award”. May 2013

“The Innovation in Design Award recognizes three elements of the lofts: the comparison of two different building approaches to high performance buildings including Passive House Standards in the north building; new workforce housing partially designed to serve young adults who have aged out of the foster care system; and the creation of a gateway development for the Uptown neighborhood.”

Powderkeg Brewing Company Looks to Alpen to Improve Efficiency of Historic Niwot Storefront

When head brewers and founders of Powderkeg Brewing Company began planning renovation of their new location in historic Niwot, Colorado, they may not have realized the challenge they would face: not only would they need to renovate the historic building’s exterior facade to improve energy efficiency to meet more stringent building code requirements quickly being adopted in Colorado’s front range counties; but they also needed any exterior renovation work to gain favor and approval by the Longmont and Boulder County historic preservation committees.

Working together with the owner of Finger Pianos, who previously owned and occupied the historic Niwot storefront space, Powderkeg brewers approached Alpen HPP for a window solution that would meet the energy efficiency and historic preservation goals as well as improve comfort, ventilation and useability of the space for its new purpose as a modern craft brew taproom.

Alpen HPP rose to the occasion, presenting multiple options for design team and historic committee review.  Quickly the decision came to rest on custom oversized double-hung windows with simulated divided light grids that captured the essence of the historic true-divided light windows while satisfying the needs of future craft beer enthusiast occupants.  Construction is still underway, so here are some in-progress “before and after” photos:

PHIUS Posts Certified Window Data

2013-10-10 v3.4 Alpen 925 HPfixed 107










The Passive House Institute, US (PHIUS) Certified Data for Windows program has officially launched its new online searchable database including listings of certified, PHPP-ready performance data for Alpen high performance fiberglass windows and several other North American and European window products.  GreenBuildingAdvisors.com expertly covered the PHIUS announcement in this April 7, 2014 article.

Program organizer Graham Wright provided this March 28 interview to further clarify PHIUS Certification program goals and address any confusion regarding differences between it and window certification programs by Passive House International (PHI), and others.

Alpen HPP is proud to be an early adopter of the program, becoming the first window manufacturer in North America to have products certified, and seeks additional product certifications in the coming months. Performance data for Alpen windows that already have been PHIUS certified can be found both on the PHIUS website and on Alpen’s Passive House page.

Staying at the forefront of the Passive House performance movement, Alpen’s technical sales team is actively researching and listening to leaders in the industry to learn and compile helpful tools for designers and homeowners to use in their window selection process.  A new white paper co-written by RDH Engineers addressing differences among PHIUS, PHI, NFRC and other simulation programs was presented at this year’s Passive House Northwest conference, stay tuned to Alpen’s News Post website for a link to the final article, expected to be published in full this spring.

Alpen windows in Honda Smart Home US

Alpen windows play integral role in net-zero energy performance of Honda Smart Home in Davis, California. A new video series on the Honda Home website explains how the home’s heating, cooling and electrical systems are automatically controlled to achieve net-zero energy performance.

Designers recognized that before equipping the home with renewable energy solar panels, the building envelope must be well-insulating and air-tight, so they selected Alpen high performance fiberglass windows:

“The Honda Smart Home’s south-facing windows are optimized for heating and cooling, while the north-facing windows are positioned to maximize natural light and ventilation. This will keep the home naturally cool in the summer and warm in the winter. Double stud walls, cool roofing material and a fully insulated concrete slab all contribute to the home’s energy efficiency.”

Alpen’s casement windows were also retrofitted with motorized operators so that the windows will automatically open and close to provide ventilation and cooling when the home needs it most.

Other articles announcing the completion of this precedent-setting home can be found here:

Brookfield Passive House Featured in Builder Magazine

The Brookfield Passive House, built by Midtown Residential, continues to receive media attention.  Most recently, the home was featured in the February 2014 edition of Builder Magazine. A well-written article highlighting key features and attributes of Colorado’s first Passive House certified by Passive House Institute US, and the first certified Passive House in the nation built by a production home builder.  The article can be viewed online at: www.builderonline.com/design/passive-expressive and is accompanied by a beautifully orchestrated professional photograph slideshow.

The Brookfield Passive House used Alpen’s 925 Series twin-film/quad-cavity fiberglass windows with directionally-tuned high and low solar heat gain glazing.  Boasting an impressive U-0.08 center-of-glass thermal performance, 925 Series windows insulate the building envelope and provide critical solar heat gain on the south elevation to offset the home’s energy needs.
