Home renovation: where to start – By Kate Wagner- Curbed

Similarly, it’s a common fallacy that (unless you are renovating your house to passive house energy standards) new windows are more energy efficient or durable than historic ones. First, it will take up to 240 years to recoup enough money from energy savings to pay back the cost of installing replacement windows. Second, let’s be real: New windows are not nearly as good looking. Old windows are very hard to replace, but much easier and often cheaper to restore to modern standards. Finally, no other types of

Green Building: Why Waste a Window? — Environmental Protection

Introduced more than30 years ago, window film today is engineered using advanced technology to deliver energy savings similar to low-e windows, yet at a fraction of what replacement windows cost. Just like new windows and doors, window film is rated by the NFRC (National Fenestration Rating Council), so homeowners and property managers can be sure of the benefits. For single-family homes, window film installation costs can range from $4 to $11 per square foot, depending on the location and type of window film installed, and the process can be completed in one or two days, without a major disruption in use of the rooms where the windows are located.

The Ancient Party Barn Went from 18th Century to Smart | Digital Trends

The buildings — the barn, stables, and dairy — on Staple Farm in Kent, England were in disrepair. The firm worked to salvage what they could and turn the barn into a home away from home for the couple. Though they wanted to maintain the “barn’s brooding presence,” according to the architects, they added modern amenities like a ground-source heat pump, LED lamps, and security systems. The lights, HVAC system, and security systems are all Internet-connected, so the owners can monitor their barn when they travel. There’s also a fireplace built into the spiral staircase, that leads up to the mezzanine sleeping area.

Passivhaus – Ezra Builders

 

Ezra Builders is setting a new standard in Northern Arizona for sustainability through Passivhaus design. As a Certified Passive House Consultant (CPHC), Tom has been trained by the certifying and training authority of the United States, the Passive House Institute US (PHIUS). He has had a direct involvement in two of the completed passive house projects in the Portland, OR area. At the Karuna Passive House, he acted as one of the Quality Control personnel during the insulation phase. Spending more time in the field at the Pumpkin Ridge Passive House, he worked on the structural framing, air barrier install, door and window install. Through his exposure and experience he believes the passivhaus (passive house) standard is one of the few ways to truly build sustainably and is setting out to do just that.

Resource efficient house at Ravenscraig

The Resource Efficient House aims to be a show home for affordable sustainable building

Inside, the house uses a variety of recycled materials in the fixtures and fittings.

The kitchen work surfaces are made from material reprocessed from recycled coffee cups.

Recycled paint is used for the decoration and the kitchen bar stools are made from reclaimed wood from whisky barrels.

The house also uses heating, lighting and water conservation measures to make it more energy efficient and affordable to live in.

Identifying Green Building Materials » Greener Ideal

green building materials

Anyone building or renovating a home today will almost certainly be keeping energy efficiency in mind. According to the research that’s been done, approximately 40% of all raw materials used each year are used in building and construction. This amounts of over 3 billion tons of resources each year, and many builders and home owners are trying to do their best to reduce those numbers. When evaluating building materials, there are a lot of factors to consider, and this article should serve as an effective guide to understanding the different elements surrounding green building materials.

First and foremost, the product itself must come from a renewable resource or process. For example, recycled materials from demolished buildings, bamboo or straw, which are plentiful and rapidly renewable, or linoleum, which is inexpensive to manufacture.

Comfort meets energy-efficiency in a restored Holy Cross shotgun | NOLA.com

Tracy Nelson's Holy Cross shotgun

A TWO-WAY STREET: Nelson makes her old home more energy efficient by “interacting” with it. During the hottest months, she closes the shutters over the doors while leaving the slats open to keep the sun at bay. In winter, the shutters hold heat inside. Her November energy bill was $40.

“Besides, I love the visual of the shutters behind the door,” she said.

Antique Eastlake doors found at The Bank, an architectural salvage store, create a tight seal against the Louisiana climate.

Dittrich-Lips Art Glass cut red, green and purple glass for her kitchen door, which lets in sunlight and splashes of vivid color. Beautiful blue and rose glass from the 1930s or ’40s in the bedroom door came from Attenhofer’s Stained Glass Studio in Metairie.

Nelson also restored the home’s original plaster walls.

“Plaster is energy-efficient and keeps you incredibly cool,” she said. In her estimation, the destruction of plaster walls and hardwood floors after Hurricane Katrina represented real architectural tragedies.

Runkel says the Weatherization Meets Historic Preservation event was a “great educational tool.” The majority of Portland’s homes were built before World War II and residents are worried about destroying the “historic character” of the homes if they make improvements, he says.

The event provided a way to introduce a discussion about home energy upgrades, Runkel notes. “It gave them some handholds and footholds of understanding the concepts of energy efficiency.”

“And it was a lot less intimidating to consider what could be done,” he adds.

Runkel praises the homeowners for the success of Weatherization Meets Historic Preservation. “This is one of those cases where it really was the initiative of the Foxes.”

The project was important, Roy explains, because it proved energy efficiency upgrades could be done in a way that doesn’t harm historic homes. “If people are willing to do a little creative thinking, you really can leave the old fabric of the house intact.”

Deep Energy Retrofit Demonstrates Significant Energy Savings With Help of Columbia Gas of Massachusetts – MarketWatch

 

CET has transformed a 100-year-old brick mill building into a modern green building with the help of funding from Columbia Gas. The building will house the EcoBuilding Bargains store, a non-profit recycled construction materials retail establishment.

According to the Environmental Protection Agency similar commercial buildings and manufacturing plants account for nearly half of all U.S. energy consumption or $2 billion a year.

This EcoBuilding Bargains store is a green standard-bearer, using only about 1/2 of the energy than a normal building of its size, according to John Majercak, CET’s Executive Director.

The $3.3 million energy-efficient makeover of the historic structure is a forerunner in sustainable practices and is just one of the many “Deep Energy Retrofits” (or superbly-insulated, highly-airtight buildings that dramatically reduce heat loss) supported by Columbia Gas around the Commonwealth.
