Around the World: Housing 4.0

A region in Europe is looking at how to improve building methods to help move towards EU 2030 energy goals.
Around the World: Housing 4.0

Framework climate and energy goals. As the most industrialized region in NWE, the private housing sector also accounts for almost one-third of all C02 emissions. The EU 2030 Framework goals are to cut C02 emissions by 40%, increase the use of renewable energy by 27% and to provide at least 27% energy savings across Europe.

Interreg North-West Europe project Housing 4.0 Energy (H4.0E) is a group of companies and individuals around NWE, working together to solve their housing and energy crisis. H4.0E is funded by € 2.5 Million in European Regional Development Fund (ERDF) (perspective: the ERDF total budget is € 4.2 Million) and looks to develop low-energy, low-carbon, near-zero energy affordable housing that is easily repeatable using digitization.

H4.0E is focused on a Design for Manufacturing and Assembly (DfMA) approach using digital design and self-building to simplify the building process. The 48 near zero energy/zero energy pilot homes will be built within the first 18 months of the three-and-a-half-year long project. Below are the project areas and goals for each area:

  • Almere, Netherlands
    • Goals: Demonstrate digital design and self-building in urban areas
  • Flemish Brabant, Belgium
    • Goals: Social good model - NZEH/ZEH units in rural areas will be rented to people on the waiting list of Belgium’s local social renting agency
  • Schwäbisch Gmünd, Germany
    • Goals: Multiple NZEH/ZEH buildings will be built for student housing
  • Carlow, Kilkenny & Wexford, Ireland
    • Goals: Build NZEH/ZEH units for low-income groups in rural areas while monitoring user behavior

The data from each of the pilot projects will be collected for analysis and parallel testing will be conducted for big picture comparisons and educational purposes, however, each project area will stay focused on their specific goals.

Where Energy Advancements Will Take Us

Where Energy Advancements Will Take Us

Last week we wrote about a couple funding opportunities through the Department of Energy. Another $33.5 million is now available through the Building Technologies Office for energy efficient, advanced building construction technologies and practices. The BTO’s focus will be to “develop deep energy retrofit and new construction technologies that holistically tackle a combination of envelope, heating, cooling, water heating, and ventilation issues, and hold appeal for both building owners and occupants.” Concept papers are due 6/10/19.

The topics of interest for this FOA are:

  1. Integrated Building Retrofits
  2. New Construction Technologies
  3. Advanced Technology Integration

Why should you care about these types of announcements? Because they are opportunities for us to advance our industry and to take advantage of the energy breakthroughs that are continuing to push down the cost of renewable energy.

Solar farms are showing up in communities and large corporations are signing contracts with wind farms. A deal in Chile was recently signed that should supply solar energy at 2.91 cents per kWh and drop energy costs for businesses there to around 25% by 2021.

Last fall, a northern Indiana utility company announced it will invest in renewable energy and by 2028 they expect 65% of the electricity they generate will come from wind, solar, and battery storage... and 0% from coal.  Additionally, JinkoSolar recently made a deal with the largest power generator in the U.S., which will be purchasing around 7 million panels over four years.

Both decisions were based on the economic case for renewable energy.

These advancements we’re seeing, including improvements in areas like battery storage, will only create greater opportunity in our industry to push innovation further - and get us closer to 100% renewable energy and a world filled with zero energy homes.

DOE to Invest $98 Million in Research and Development Programs

The DOE is prepared to invest $98 million towards domestic manufacturing of energy storage and technologies.
DOE to Invest $98 Million in Research and Development Programs

A recent Funding Opportunity Announcement (FOA) by the Department of Energy (DOE) is requesting proposals in three areas to improve U.S. competitiveness surrounding energy technologies and domestic manufacturing for energy storage. The FOA will look to support innovative, advanced manufacturing research and development programs focused on advanced materials, industrial efficiency and productivity, and the electrical grid.

"By focusing on energy-related advanced manufacturing technologies, we are building a new era of manufacturing that will stimulate the economy, create jobs and build American energy independence," says U.S. Secretary of Energy Rick Perry.

$98 million in awards will be funded to high-impact, early to mid-stage research in three topic areas:

  • Topic 1: Innovations for the Manufacture of Advanced Materials
    Focuses on employing machine learning to develop better batteries, phase change storage materials for heating and cooling applications, and new semiconductors that convert temperature differences into electricity.  A key focus is on developing and scaling new, low-cost manufacturing processes to catalyze increased domestic battery manufacturing for vehicle and stationary applications.
  • Topic 2: Lower Thermal Budget Processes for Industrial Efficiency & Productivity
    With 70% of all process energy use related to heating, this topic focuses on novel research on industrial process drying technologies that increase energy efficiency throughput and product quality.  It also seeks new ideas on process intensification to reduce overall heating energy.
  • Topic 3: Connected, Flexible and Efficient Manufacturing Facilities and Energy Systems
    With recent advances in new, wide-bandgap semiconductors supported by DOE, this topic seeks application of more efficient industrial power conversion equipment and new opportunities for converting process energy to electrical energy and better integrating it with the electrical grid.  It also seeks advancements in combined heat and power that result in higher electrical efficiencies.

If you have an eligible project for which you’d like to submit a concept paper, or if you have questions, or would like to view examples of sub-topics, you can learn more here.  A cost-share of at least 20% will be required for research and development projects.  Concept papers are due on or before June 20, 2019.

Why I Love the Solar Decathlon Design Challenge!

A Former Competitor’s Take on the Solar Decathlon Design Challenge
Why I Love the Solar Decathlon Design Challenge!

by Nathan Kahre

Long nights, worrying over designs, stressing over deadlines, and more work than I have ever been put through before, this is what I remember from when I competed in what was Race to Zero, now the Solar Decathlon Design Challenge.  What I also remember is the time spent working with a team, iterations of energy models, and the joy of getting to present all my hard work.

I thank Solar Decathlon Design Challenge for the opportunities that I have had in the high-performance home industry.  The competition forced me to take the theoretical and make it real.  It also put me in connection with experts across the country and landed me my first job in the industry.  After spending a day of stressing over the competition, I ended up meeting this crazy production builder that was focusing on net zero homes and wanted to implement new products and techniques to improve the indoor air quality in their homes and hopefully impact the health of the occupants.  That twenty-minute conversation completely changed my perspective on what a production home builder could be, landed me a successful internship, and now 3 years later I have turned into that crazy production builder myself.  Finding ways to enable these types of conversations and connect students to all the great builders across the country is a passion of mine.  



I am lucky enough that the Solar Decathlon Design Challenge happens in my backyard and getting to attend the competition is a highlight of my year.  I am constantly impressed by the time commitment and skill each of the teams portrays.  This year was no exception with 45 teams competing from 37 collegiate institutions from across the United States, along with teams from England, India, Saudi Arabia, Germany, Panama, and Brazil.  The diversity of projects and solutions employed were thoughtful and showed a group of caring hardworking students excited about net zero construction.  The Solar Decathlon is truly developing the next generation of building scientists, architects, and construction professionals; and equipping them with the skills necessary to build high performance homes, apartments, office buildings, and schools.

Now in its sixth year, the design competition challenges students to develop market-ready net zero home designs across a variety of design divisions (single family urban and suburban, attached housing, small multifamily, office buildings, and schools).  Students can’t just develop a pretty home, but must also integrate building science knowledge, market analysis, and construction management skills, and wrap it up into a 20-minute presentation in front a panel of experts.  This leads to 6 division winners and one grand winner.  Take a look at this year’s winners and their presentations here.

What happens next?  There is a pool of talented students, many of whom are ready to enter the workforce, ready to contribute to the high-performance construction industry. Last year, for the first time, EEBA provided scholarships to representatives from each of the winning teams to come and experience the High Performance Home Summit in San Diego.  EEBA’s Next Generation Development Committee is working hard to make this happen again and bring team representatives from the winning residential teams to the 2019 Summit in Denver, CO.
