Happy Homeowner Reports Success in Winter Window Installation

Even though it’s almost winter, it’s not too late to replace or install new energy efficient windows!  Braving the chilly Colorado temperatures last week, one Conifer, CO Alpen window owner forged ahead in his window installation work, sending us this update from the field:

 “My daughter and I installed the final three [windows] today … the last one when it was 27 degrees and snowing. They look great … clean, simple, solid and a pleasure to operate. I’m very happy !”

Passive House Institute Certified Projects Database Now Online

Passive House PHI DatabaseThe International Passive House Association (iPHA) recently published their searchable database of Passive House Certified projects both completed and in construction.  As similar as the diversity in the individual home designs is the diversity of window products used.  There appear to be as many European window products as there are North American windows.

Among certified homes with North American windows, Alpen HPP is pleased to see that the large majority are pultruded fiberglass windows, including such premium products as Cascadia Windows, Accurate Dorwin, Inline and, of course, Serious Energy – who’s facilities Alpen HPP purchased in late 2012.

Although we retained the “X25″ naming convention, Alpen HPP has  taken great strides to improve the old Serious window line, and to make it Passive House friendly – from adding glass packages to accessories, to becoming the first Passive House Institute, US (PHIUS) Certified Window.

Check out the new searchable iPHA database online here:  http://passivhausprojekte.de/index.php?lang=en#

How many Alpen/Serious projects can you count?

Landenberg Today touts house with Alpen windows as “A Home for the Next Century”

October 2, 2014-

Landenberg Today magazine Fall 2014 edition features multi-page article on an Alpen window home, calling it “A Home for the Next Century.”

eos-rebel-t5i_1074Nestled in a serene 7-acre camp in Landenberg, PA in Chester County, about 20 miles Southwest of Philadelphia, KampKaolin is a 2,700 square foot high performance home inspired, designed and built following the Passive House approach.  The construction team at Hugh J Lofting Construction Management emphasize use of “low-impact” building materials and methods throughout the build cycle.

As illustrated in their beautifully and meticulously maintained blog documenting all stages of the design-build process, the home’s owners explain how Alpen high performance fiberglass windows help create the super-insulated, air-tight building envelope a high performance home requires.

Hugh Lofting Construction further emphasizes how Alpen windows integrate with an air-tight envelope in their online installation video recorded on-site at KampKaolin during construction.

With such precision, care and attention to detail, this Alpen window project is sure to pass even the most stringent blower door test and air infiltration requirements of a super-efficient, zero-energy ready home of tomorrow.

Holladay Expertly Recaps Successes of Passive House Network 2014 Conference

September 26, 2014:

On the heels of another tremendously successful Passive House Conference – this time in Portland, Maine, hosted by the North American Passive House Network Alpen HPP thanks the NAPHN community for generously hosting the event as well as all of the experts in the field who are recapping important lessons from the event.

Most recently, Green Building Advisor, Martin Holladay’s blog applauds the conference attendees for their intellect and openness toward sharing information and learnings from the field.  Holladay’s blog goes on to summarize key messages delivered by Passive House founder Dr. Wolfgang Feist’s in his keynote address.  Some of these comments with particular residence to us here at Alpen HPP include:

Feist said, “Good windows are an important part of the development of Passivhaus.” As better building materials become available, Feist predicted, “we can reduce the overall investment costs.”

When calculating the value of any investment in energy features, Feist advised, “Forget about payback time. Payback is misleading. It is not a good measure for the economic result of an investment.” Instead, Feist advised the audience to focus on net present value. (For more information on net present value calculations, see Payback Calculations for Energy-Efficiency Improvements.)

Read Holladay’s full conference recap online here and be sure to check out the NAPHN Twitter feed for play-by-play remarks from speakers, attendees and the Passive House Network community captured during the event proceedings.

NAPHC Conference Recap: “It just keeps getting better,”

remarks Allison Bailes III in her Green Building Advisor article, “Highlights from the North American Passive House Conference.”  Allison’s article captures the high-energy, intellectually stimulating, ambiance of this year’s events hosted by the Passive House Alliance, US (PHAUS) and the Passive House Institute, US (PHIUS) in San Francisco.

The passive house movement is probably the most exciting area to work in the field of building science. When you push out to the edge to see just how far you can go — or should go — it’s possible to make progress that could hardly be imagined before..

Passive House leader and innovator, Kat Klingenberg, gave a broader overview of this year’s conference on her blog, noting that the greater Passive House movement is growing rapidly in a positive direction, with ever-increasing numbers of contributors with great depths of experience and knowledge.

Together you submitted nearly 100 abstracts and we had a hell of a time to choosing the best ones. We ended up with an unprecedented total of 72 sessions in 4 tracks this year, more than ever before.

Every year we say “This was the best passive house conference ever, we better stop now, we can’t possibly top this experience, the quality of the presenters, the “meat on the building science bones” presentations, technical details and specific construction solutions, cutting edge projects of all building types showcased throughout all climate zones, policy and government role discussions and incentives…”

Alpen HPP thanks PHAUS, PHIUS and all of the excellent speakers, presenters and thinkers who contributed to a fantastic conference experience.  We at Alpen learned a lot from all of you and look forward to applying all that we learned to product improvements and offerings in our high performance fiberglass window line.

Empire State Building with Alpen Glass Exceeds Energy Savings for 3rd Straight Year

In 2010 Alpen glass innovators executed an extraordinary window energy efficiency upgrade at the Empire State Building as part of a whole building efficiency improvement project that included 8 core improvement measures.  Today, Johnson Controls reports:

World’s Most Famous Office Building Exceeds Energy Efficiency Savings for 3rd Consecutive Year; Annual Savings 16% Above Target

web content_johnson controls

The Empire State Building has surpassed the energy savings guaranteed through its innovative energy-efficiency program for the third consecutive year.

Over the past three years, the program has generated a total of approximately $7.5 million in energy savings at the landmark building. The savings is the result of continued enhancement of the iconic building’s new systems and the addition of many new tenants occupying hundreds of thousands of square feet of office space retrofitted according to program guidelines.

Window improvements are continuously cited as one of the most dramatic contributors to these ongoing savings exceeding all expected results.

Knowing windows would be important, the design team wondered how to execute the improvement: complete removal of the relatively new, good condition, 1994 thermally broken aluminum frames was noted as an unnecessary waste and too costly.  One day while watching maintenance staff clean the double-hung windows, Alpen Inc. founder and suspended film pioneer, Robert Clarke, saw an incredible opportunity to improve center-of-glass performance while re-using over 95% of the existing glass.

Starting in March, 2010, the Alpen and Serious Energy team built a suspended coated film fabrication line  inside the Empire State Building.  Over the course of 8 months, the team removed and replaced all 6,514 insulated glass units from the windows (rate of 150 per night), to add a low-e coated suspended film in the center of the units to create a triple pane, low-e coated window.

With Krypton gas fill, the new Alpen glass achieved center-of-glass U-value reductions of:

  • North:  -73%  (from U-0.48  to new U-0.13)
  • South/East/West:  -59%  (from U-0.48 to new U-0.20) plus -52% solar gain reduction
