The Evolution Continues

The design team has been hard at work completing the details of the design, testing assumptions and continuing to prepare the drawing for submission to obtain permits. During this process, it became obvious that the solar (PV) panels would not drive a high enough yield positioned on the top of the garage/workshop as the sun is partially obstructed a point in the day.  The decision was made to relocate them to the top of the main building, but in order to do so; a redesign of the roof and associated terraces would need to be done. 

As you can see in the newest rendering, Jim and his team have done an amazing job of integrating the panels on to a new roof awning that cantilevers over the fourth floor deck.  This provides us protection from the sun and double the usable roof square footage.  Another change is the integration of the glass panels that sit atop the brick; they are nearly two and a half tall glass panels that wrap both structures.   They provide light and flow-through ventilation, given half of them are fully operational.  There are many other evolutionary changes and will be more obvious as I post different views and new renderings.

During early January, we will begin to develop a “thermal model” in order to maximize engineering options and to validate final design. Thermal modeling answers questions about airflow and temperature distribution under various weather conditions.   In addition it allows control over PV design and performance. The goal of energy modeling is to accurately predict the energy use of this building.  While costly, this will allow us to play ‘what if’ with various products, finishes, and design options to insure we reach our goal of net zero-energy, before we actually begin construction.

It's Out In The Open

At 8:00 AM today, this release hit the wire, unveiling our very ambitious project to a larger group.  The reaction has been great and I have been getting a bunch of press inquires.  

New York City’s First ‘Zero Energy Building’ Coming to the

Red Hook Section of Brooklyn

Innovative Facility To Be Completed by Summer 2010

FOR IMMEDIATE RELEASE New York, NY – December 03, 2009 Designs for New York’s first sustainable zero-energy, live/work building are nearing completion, with ground-breaking scheduled for February and completion planned for summer 2010.  This structure is expected to become a distinctive new addition to the Red Hook section of Brooklyn.

As defined by the US Department of Energy, “a net zero-energy building (ZEB) is a residential or commercial building with greatly reduced energy needs through efficiency gains such that the balance of energy needs can be supplied with renewable technologies.”  Basically the ZEB concept is the idea that buildings can meet all their energy needs from low-cost, locally available, nonpolluting, renewable sources such as solar or wind power.

This approximately 4,000 square foot facility will house a studio/workshop, offices for a digital business, garages and an apartment, as well as outdoor green space. The form of the house is inspired by the shipping containers stacked along the adjacent waterfront. Modular units, proportioned similarly to shipping containers are stacked and shifted to create a variety of terraces and overviews to take advantage of the areas amazing harbor views.

The project, called ‘Redhook Green’ is the brainchild of New York technology and media entrepreneur, Jay Amato. 

“I’m thrilled that Redhook Green will become a very visible symbol of the continuing reinvention of one of New York City’s oldest neighborhoods,” said Mr. Amato.  “But I’m even more excited that I could practically illustrate the movement towards zero-energy building to the world’s greatest city.  Bringing to bear exciting new building materials, improved wind and solar technologies and more energy-efficient HVAC and home appliances, as well as state of the art sustainability strategies, Redhook Green will be a powerful answer to the question of what urban centers can do to reduce our dependency on foreign oil via renewable resources and to significantly reduce greenhouse-gas emissions.

With a long history as a shipping port and industrial district, Red Hook – not quite two miles across from the Battery at the tip of Manhattan – is thoroughly urban. In the evenings, however, it is as quiet as a remote and leafy suburb, bounded by water on three sides and the elevated Gowanus Expressway on the remaining side.  While other Brooklyn waterfront neighborhoods like Williamsburg and Dumbo have developed an image of youthful urban chic, Red Hook remained a gritty industrial district until the recent addition of Fairway, IKEA and the New York Water Taxi. Now, Red Hook's eclectic mix of artists and industrial businesses has created a neighborhood dubbed "Residustrial" in 2008 by artist and resident John P. Missale.

Award winning New York firm, Garrison Architects, located in Dumbo, Brooklyn, is the chief designer overseeing Redhook Green. Garrison has assembled a unique group of designers, engineers, and manufacturers to innovate for this project.

"Jay Amato’s Red Hook project draws from several promising trajectories – abstract modernism, modular construction, and zero energy consumption.  By combining state of the art approaches to all three in one structure we have moved the potential for affordable, ecologically sound, urban dwellings several steps forward," said James Garrison, Principal in Charge of Garrison Architects.

Simple and cost effective sustainability strategies are used to conserve and produce energy, conserve resources, and create a healthful environment. This sustainability approach was developed though an extensive research project that included digital energy modeling, detailed life cycle cost analysis of construction components and their related maintenance and replacement costs. Here are a few of its features:

·       8kw annual photovoltaic generating capacity, grid connected.

·       8kw annual comprehensive household energy budget including heating and air conditioning.

·       High performance building envelope that eliminates thermal bridging and achieves an average thermal resistance of R50.

·       Wall and roof systems vented to eliminate moisture build up and use “smart” moisture barriers to allow air movement in warm months.

·       Integrated south facing thermal solar wall generates warm air that is fed to the building ventilation system.

·       Heating and cooling provided by high efficiency electric heat pumps.

·       Whole house heat exchange ventilation system insuring air quality and recovering energy from conditioned air.

“In my entire career building and leading businesses, nothing has given me more satisfaction than developing this project,” added Jay Amato. “We are transforming what is essentially an empty space into a structure that can serve as an example of how we can live and work responsibly. This is truly gratifying.”

It's All in The Details

The original schematics for our building are being detailed and a finalized design is emerging.   It is our hope that we will be presenting the completed package to the NYC Department of Buildings for permit approval.  I promised that I would share details as they became available, so as I asked Jim Garrison to describe the building from his perspective as well as more of components that get us to zero-energy!

This structure combines open and flexible planning with integrated gardens, state of the art sustainability strategies, and modular factory fabrication. It is designed to be a zero energy structure, as it will produce as much energy as it consumes.

The first floor consists of large live/work loft areas arranged on either side of an exterior court. Glass walls adjoining the court (see images) can be opened to allow the complete integration of the garden, living, and work areas. The form of the house is inspired by the shipping containers stacked along the adjacent waterfront. Modular units, proportioned similarly to shipping containers are stacked and shifted to create a variety of terraces and overviews.

Zero-Energy Building - A World Wide Movement to ZEB

I need to develop a press release to announce this project.   My goal is drive awareness of Redhook Green in an effort to obtain technological, equipment and product support from green-minded manufacturers of appliances, electronics, and furnishings, just to name a few.  I discovered there was no concise way to describe the movement towards lower or zero energy building, so I decided that I needed to give it a try myself.  

 As the United States moves to reduce its dependency on foreign oil via renewable resources and to significantly reducing greenhouse-gas emissions, automobiles have typically been the favorite targets of the press and politicians, but in reality buildings have a huge impact on energy use and the environment. According to the Energy Information Agency, commercial and residential buildings use almost 40% of the primary energy and approximately 70% of the electricity in the United States.

 There is a perfect storm of sorts brewing in the world of new construction.  As building technology improves, architects have developed exciting passive designs to reduce energy needs in order to maintain temperature throughout the sun's daily and annual cycles while reducing the requirement for active heating and cooling systems. Next add to that the ever-improving performance of wind and solar generation while continuing to drive lower costs to implement. And finally, manufactures are engineering more energy efficient HVAC and home appliances to reduce consumption and increase efficiency. The intersection of these phenomena’s is the Zero-Energy Building.

As defined by the US Department of Energy, “a net zero-energy building (ZEB) is a residential or commercial building with greatly reduced energy needs through efficiency gains such that the balance of energy needs can be supplied with renewable technologies.”  Basically the ZEB concept is the idea that buildings can meet all their energy needs from low-cost, locally available, nonpolluting, renewable sources such as solar or wind power. That building can generate enough renewable energy on site to equal or exceed its annual energy use. A zero energy building typically uses traditional energy sources such as the electric and natural gas utilities when on-site generation does not meet the need. When the on-site generation is greater than the building’s loads, excess electricity is sold to the local utility via the power grid. By using the grid to account for the energy balance, excess production can offset later energy use.

 There is a growing trend to for governments around the world to embrace the concepts of zero-energy buildings; a few examples include California and the European Union.

 Every two years, the California Energy Commission (CEC) releases an Integrated Energy Policy Report, in which it makes recommendations for energy policy in the state, including changes to the energy efficiency portion of the building codes. In its 2007 report, CEC recommends adjusting the code to require net-zero-energy performance in residential buildings by 2020 and in commercial buildings by 2030.   There are only a few examples of ZEB building in the U.S. according to the Department of Energy's Zero Energy Buildings Database that features profiles of commercial buildings.

 The European Union has taken a huge step toward zero-energy building.  Earlier this month an agreement was reached by representatives of the European Parliament and the Council, aiming to extend the scope and strengthening the current directive to upgrade the national building codes and by launching an ambitious policy of nearly zero energy buildings, so that all new buildings will be nearly zero energy as of 2020.

 In the EU buildings are responsible for 40% of energy consumption and 36% of CO2 emissions. It is estimated that, by strengthening the provisions of the directive on energy performance, they could achieve a reduction in its greenhouse gas emissions equivalent to 70% of the current EU Kyoto target. In addition to this, these improvements could save citizens around 300€ per annum per household in their energy bills, while boosting the construction and building renovation industry in Europe.  Energy Commissioner Andris Piebalgs said: "Energy performance of buildings is key to achieving our EU Climate & Energy objectives for 2020, namely the reduction of Greenhouse gas emissions and the achievement of a 20% of energy savings. By this agreement, the EU is sending a strong message to the forthcoming climate negotiations in Copenhagen. Improving the energy performance of buildings is a cost effective way of fighting against climate change and improving energy security, while also boosting the building sector and the EU economy as a whole."
