What is a Passive House?

What is a Passive House?

I recently saw listed on the Green City Blue Lake calendar an opportunity to tour a passive house that was recently constructed in the Cleveland area this week.  The tour was booked, but I stopped by yesterday at the site of the house to take a peek.

What is a passive house? (or Passivhaus in German?) The basic idea of a Passive House is to reduce the energy usage of a home by 90% over traditional code built homes, and is the highest energy standard in a building.  Well-insulated, almost air-tight – a passive house minimizes energy loss through excellent thermal performance, exceptional airtightness with mechanical ventilation.

“Passive”  describes the idea of energy receptivity and retention  The house works with natural resources and free solar energy, and does not work with any “active” systems.

Often passive houses have triple-glazed windows, are super-insulated, and have a airtight shell around it – which helps balance heating, cooling, and ventilation.

In the last 10 years more than 15,000 buildings in Europe have been designed and built or remodeled to the passive house standard.  -Single and multifamily residences, schools, factories and office buildings have all been built with the passive house design.  There have been over 30,000 passive houses built to date, many after the year 2000.

In the Cleveland area, the second house applying for Passive House certification was completed and is the Butler-Nissen house located at 2200 Devonshire Dr. in Cleveland Heights, OH. The tour of the house was booked last Saturday, but be on the lookout for more tours of the home in the future.

Barbie has a Dream House … with Solar Panels and a Meditation Room

Barbie has a Dream House … with Solar Panels and a Meditation Room

This past summer, the American Institute of Architects (AIA) sponsored a competition for architects to design their own interpretation of a Barbie® DreamHouse™.  Five finalists were chosen, and then they were put to a public vote.  The winning design, which was submitted by Ting Li, Assoc. AIA, LEED AP and Maja Paklar, Assoc. AIA,  features solar panels, a landscaped rooftop and irrigation system, operable shading devices, bamboo flooring, and low flow toilet and sink fixtures.

It also has a meditation space, a home gym, and a 1,500 square foot entertainment area.  Spaces in the house include a computer-controlled tower closet and a 1,500-square-foot space for entertainment facilities and a chef’s kitchen.  The house is designed to be built on a bluff overlooking the Pacific Ocean.

The contest coincided with the launch of a new Barbie doll – “Barbie I Can Be… Architect Doll” with Mattel, in an effort to engage and inspire young girls to experience the world of architecture and design thinking.  Architect Barbie is promoted with the phrase, “Your daughter can play out her dream of being an innovative, creative architect!” and the doll has a outfit featuring the bold colors and clean lines of the city skyline, has black rimmed glasses, a hart hat, and a carrying case for her latest designs, and a model Dream House.

The winning Dreamhouse is not planned to be built, so it seems like Barbie will still be living in her old place for now.

A Gas Shortage? Gas Bag Vehicles

A Gas Shortage? Gas Bag Vehicles

During World War I and II, there was a limited supply of gasoline.  One alternative to cars running on  gasoline was the gas bag vehicle.  Cars and buses were converted to being fueled by uncompressed gas, which was stored on the roof of the vehicle in a balloon tank.

These gas bag vehicles were built in France, the Netherlands, Germany and England and were an improvised solution to the gasoline shortage.  The fuel in the balloons were powered by what was called “town gas” or “street gas,” which is a by-product of turning coal into coke (which is used to make iron.)   The tanks were either hard or soft bag-like structures, put on the top of cars and buses.  The tanks were large, since more gas was needed to get adequate mileage.

With the gas bag vehicles, it was easy to tell how much fuel was left since the gas bag would deflate as the car was driven. One risk of using the vehicles was the risk of fire, and obstacles that were overhead.  Drivers had to know the heights of bridges before driving underneath.  The vehicles could only go 30 mph, so that the fuel tank would stay secure on top of the vehicle.

Gas bag buses could still be seen in China in the 1990s, mostly in the area of Chongqing where the vehicles were used as a cheap public transportation option.

Today gas bag buses are not in use – but are interesting examples of how rising energy prices can drive energy technology innovation.

“Microtecture,” Off the Grid LED Lighting, and the Designers Accord Town Hall Meeting

“Microtecture,” Off the Grid LED Lighting, and the Designers Accord Town Hall Meeting

Last night I attended the first Designers Accord Town Hall meeting in Cleveland.  Hosted by  SmartShape Design, CIA, IDSA Northeast Ohio Chapter and AIGA Cleveland Chapter at the Cleveland Institute of Art, the event was intended to create discussion on how design can create positive environmental and social impact in the local community and beyond.

There were several presentations by designers in Cleveland which included David Levine of Wireless Environment ( a company focusing on off the grid LED lighting), King Heiple of Recharge Power (a company which produces products that are for recharging electric cars), PJ Doran, of APOC ( a group which rescues and upcycles good wood from houses) and F*SHO Collective (annual furniture show in the Cleveland area), and Doug Paige, from the Cleveland Institute of Art.

The presentations focused on presenting an overview of what the companies and groups did – and each presenter would end the presentation by framing  some key questions for discussion – which were to be discussed in later breakout sessions.

Some of the highlights of the night:

David Levine summary which included the questions, “ What if a light could go on and off the grid – like a laptop?  What can be wireless in 2015?  What if lights would store up power at night, when the cost of power is cheaper, and go off the grid during the day?”

PJ Doran presented about his current project in microtecture, trying to make small 150-200 square feet living spaces that are affordable, low-maintainance, that have a low impact on the land,  and can be moved.  His presentation was the most engaging of the night – and he showed several interesting examples of microtecture and presented the question, “How can we create creative sustainable, small living solutions?”

Doug Paige, who I work with at the Cleveland Institute of Art,  talked about a current group project he is a part of which is using biomimiciry o create solutions to the challenges of desalination of water.  (biomiciry is a process where models, systems and process of nature are examined to solve human problems.)   The project addresses the question of, “ How can we crate efficient, modular desalination systems that work with the principles or “rules” of nature?”

This was the first event organized by the Cleveland group of The Designers Accord – which is a global coalition of designers, educators, and business leaders working together to create positive environmental and social impact.  The group has a Design Education toolkit that you can view on the  site or download as a PDF.

I had to leave before the breakout and discussions began – but the information will be posted online at a later date- on the Designer Accord website  – presenting ideas about Cleveland, design, and sustainability and social impact.

Want to buy a energy smarthome?

Want to buy a energy smarthome?

The PNC ultra-high-tech SmartHome, which was constructed last spring on site at the Cleveland Museum of Natural History, moved yesterday to its permanent site on Wade Park Avenue and is for sale.  The house was put on a large flatbed – and was driven to its new location.

The Smart home is all-electric, but is designed to use 90% less heating and cooling energy than a typical home. While on site at CMNH, over 10,000 people toured the house.

The home was designed by Chuck Miller of Doty & Miller Architects in Cleveland. Certified Passive House Consultant Mark Hoberecht of HarvestBuild Associates will oversee SmartHome Cleveland’s adherence to the standards of the Passive House Institute US.

The home’s construction on its temporary site at the museum coincided with the exhibit on global climate change on display at the museum .  It also was timed with Cleveland’s 10-year campaign to remake the region’s economy through sustainable business practices which  named 2011 – the year of energy efficiency.

The super-energy efficient, two-story house is for sale and is listed with Howard Hanna for $329,000.
