Holland to Get Its Own Vertical Forest

Stefano Boeri’s Bosco Verticale idea has really taken off. Now the city of Eindhoven, the Netherlands will get it’s own vertical forest tower.  Similar buildings have already been built in Paris, France and Lausanne, Switzerland. The tower in Holland will provide affordable inner-city social housing.

The so-called Trudo Vertical Forest will be 246 ft (75 m) tall and have 19 floors. The façade will feature 125 trees, 5,200 shrubs and more than 70 species of plants. These will help cleanse the air, improving its quality, as well as provide a pleasant environment to live in.

The basic design of this tower is different than the previous versions of Bosco Verticale.  The exterior is covered in concrete planters and terraces, which jut out from the sides.

The tower will feature 125 apartment units, intended for young people looking for an affordable place to live. Each apartment will have a balcony with one tree and 20 shrubs. The Stefano Boeri Architetti intends to prefabricate the sections needed to build this tower and then assemble them on site.

The project appears to still be in the planning stage at this time, and there is no information about when construction is set to begin, nor by when it will be finished. Although given the fact that this is a prefab building, it should be erected quickly.

Here’s how a new program will fund more multifamily solar projects in California

california multifamily solar program

Multifamily housing is one of the most complicated segments for the solar industry given the competing interests of tenants and owners. California, usually the first state to do everything in solar, is trying to make this easier with a new program.

The California Public Utilities Commission (CPUC) approved of a new Solar on Multifamily Affordable Housing (SOMAH) program for low-income apartment tenants in December. The goal is provide direct benefit to the tenants from the solar systems on their apartment’s roofs.

“Usually, affordable housing apartment owners pay for the electricity used in the complex’s common areas, not the individual units. Solar PV systems installed on these properties are typically only used to offset electricity in these areas. The property owners receive the savings directly, not the ten-ants. The SOMAH program will now also offset the tenants’ individual utility bills,” says Luciana Da Silva, Adroit Energy’s Director of Marketing and Corporate Development.

This $1 billion program will provide up to $100 million annually for up to 10 years, between 2016 and 2026.  The overall target is to install at least 300 megawatts (MW) of generating capacity on qualified properties by 2030. The program is set to begin August 2018.

Although the AB 693 (Eggman, 2015) Program Administrator and bill verbiage still need to be ironed out, Adroit identified these as the major key points for owners and tenants:

How Will Tenants Directly Save from Solar?

Low-income tenants will receive credits on utility bills through tariffs, namely virtual net metering (VNEM) tariffs. VNEM tariffs provide a mechanism for allocating bill credits from system generation among the property occupants, including both common area electric accounts and the accounts of tenants.

Under SOMAH, tenants receive at least 51% of the VNEM credits from any solar project.

What’s in it for the Property Owners?

SOMAH does not exclusively help the tenants. The bill will allow 49% of VNEM tariffs to flow to common areas. This split will provide the maximum flexibility to property owners to tailor their pro-jects to their particular circumstances.

Additionally, AB 693 authors emphasize the significant value to retaining common area Time of Use (TOU) rate requirements in order “…to encourage property owners to participate in additional ener-gy efficiency, demand response, and other energy management activities.”
Solar systems owners will still be eligible to receive the 30% Federal Incentive Tax Credit will be available when owner’s purchase the system.

Which Affordable Housing Properties Qualify for SOMAH?

• The property must be located in a designated disadvantaged community as identified by the California Environmental Protection Agency (CalEPA)… Or at least 80 percent of the house-holds in the building must have household incomes at or below 60 percent of the area medi-an income
• Units must be separately metered and eligible for a virtual VNEM tariff.
• It must be an existing building
• The installed solar system must produce at least 1 kW of electricity, and not more than 5 MW, alternating current rated peak electricity.
• Your utility providers must be Pacific Gas and Electric Company, San Diego Gas & Electric Company, Southern California Edison Company, Liberty Utilities Company, and PacifiCorp Company.
• There must be at least 10 years remaining on the term of the property’s affordability restrictions.

Property Owners Cannot Hike Up the Rent

Property owners are required to sign a contract to ensure no additional costs for the system will be passed on to low-income tenants at the properties. This includes increased rents, adjustments to utility allowances, or other mechanisms. Owners must demonstrate 100% of the economic benefits of the system’s generation will be reserved for tenants through the life of the system.

The rule also applies to third-party system owners, whom must also “…provide ongoing operations and maintenance of the system, monitor energy production, and kWh production levels projected for the system are achieved.”

Ensures Job Training and Local Hiring

The commission will develop local hiring plans to promote economic development in disadvantaged communities and job training requirements similar to those currently in place for the MASH program. In addition, program service providers must produce economic benefits by providing job opportunities to residents of disadvantaged communities.

Philadelphia’s First Passive House Multi-Family Complex Ready for Occupancy

exterior

After years in limbo, Philadelphia’s first multi-family Passive House housing project is finished and on the market. Located at 219-235 W. George St., the homes were developed by the Onion Flats group in association with Domani Developers. The housing complex is known as the Onion Flats Stable. Of the projected 70 units, the team later downsized the project to only 27 units due to financial difficulties.

The units have a net living area of 2500 square feet, which includes 3 bedrooms and office space, and 3 bathrooms. About one third of the units in this development are set to be Affordable Housing units. This housing project was designed to obtain the LEED Platinum status, making it the first multi apartment complex in the US to receive this certification.

This extremely energy efficient housing project is projected to generate 100 percent of its own power from a 4.23kW PV array. The exterior envelopes are super-insulated (R-34) with the aim of greatly reducing the cooling and heating costs and overall energy expenditure. The roof is comprised of multiple 8 inch deep intensive (occupiable) and 4 inch deep extensive (non-occupiable) Green Roof Systems. The green roofs increase each unit’s insulation values, while also fulfilling 100% of the Storm Water Management needs.

The installed 430,000 gallon tank will be used to siphon water from the high water table located in close to the neighborhood. It will also act as a geo-thermal “heat-exchanger” for the building’s central heating and cooling systems. The tank will also be used as a cistern for the rainwater collected on site. Such a multi-faceted water management system will reduce flooding in the surrounding area, bring down the heating and cooling costs and be used to irrigate the green roofs.

The units are fitted with triple-pane Intus windows and doors. These windows come in R values of up to 10 and offer options such as, wood/wood, wood/aluminum, U-PVC and aluminum. All operable windows made by Intus have three weather/air sealing points and multiple locking points making them very airtight. Other specifications of Intus windows are DP 70, a decibel rating (dB) 47, and Air Leakage of 0.01. Added together, the U-window values of the Intus windows range from 0.102 – 0.16, with the Passive House standard being 0.14. The Stable flats are also fitted with Intus doors, which have multiple locking points.

The building complex is also fitted with a 260 KW Photovoltaic Panel System, and has radiant floor heating embedded in polished concrete floors. The boiler for the radiant heating is centrally located and also heats the domestic hot water for all units. The apartments are also fitted with low-flow toilets, showerheads and faucets. The units are also equipped with a Smart Home Energy-monitoring system, allowing the future occupants to monitor their energy consumption.

The factory-built units are designed so as to consume up to 90 % less energy than traditionally built apartments. The entire housing complex was designed in the popular rowhouse style, which means it fits in nicely with the other buildings in the neighborhood. This building style was also the perfect model for modular manufacturing. The foundations of the Onion Flats Stable building were constructed on site, but the rest of the structure was factory built, which reduced the construction time by 50 %.

LEED-Platinum-Habitat-Humanity-Home-build-1

In 2011, the Denver chapter of the American Institute of Architects (AIA) partnered with CAD-1, Inc. to administer a design-build competition for a home that would be built for Blue Spruce Habitat for Humanity in Kittredge, Colorado. The winning design of a duplex was submitted by Molly Blakley, Assoc. AIA; Alan Ford, AIA; Kathy Ford, AIA; and Matt Weaver, Assoc. AIA, with Alan Ford Architects P.C. as the Architect of Record.

LEED-Platinum-Habitat-Humanity-Home-build

The duplex features a super-insulated envelope to accommodate the cold microclimate on the north-facing slope of the mountain build site and a ground source heat pump. A sip system provides an R-50 walls and an R-75 roof. Principles of daylighting and ventilation are incorporated into window systems.

Currently under construction and nearing completion, the home will be occupied by Hazzell, a single mother who was abandoned in a dumpster at the age of four and grew up with foster families and in group homes, and her son, Titus. Building volunteers can sign up to assist with the build at bluespruce.volunteerhub.com through July 27, 2013. The home dedication ceremony is tentatively scheduled for July 28, 2013.

The duplex is still thousands of dollars away from its fundraising goal, with donations being accepted via credit card at givingfirst.org/habitatcolorado. Please include “AIA Denver” in the Special Instructions field of the donation form to ensure proper designation of your donation. Checks (with AIA Denver written in the Memo line) can be mailed to Habitat for Humanity of Colorado, 550 S. Wadsworth Blvd., Ste. 150, Lakewood, CO 80226.
