Going Green Part VI

Tuesday, August 31st, 2010

Over a month has passed since the Rough Inspection on the Wheaton Green Home, and Jason Werr of JAW Builders has been working tirelessly with us to succeed in reaching the Emerald level of the NAHB Green Building Program.  Neither JAW Builders nor SWA Architects is content to settle for anything less, so when the Rough Inspection indicated that we were not on pace to reach the Emerald level it was time to change course and take things to that next Emerald level.

Since our last installment of Going Green, Jason, his wife Michelle, and I have spent a number of hours investigating every section of the NAHB Green Building Program and had many conversations on what more we can do to still keep the Emerald level within reach.  It has never been a question that the home Jason is building is “green”.  Jason has taken eco-friendly home building seriously from the beginning and has every intention to follow through, but the tireless pace at which he is building the home leaves little time to document everything the NAHB requires for certification.

The Model of Efficiency

Thursday, July 29th, 2010

The social and economic climate of the day can, and typically has, had a broad affect on home design throughout time.  Our current times are no different; in fact, home design may be more driven by these factors than we have seen in over fifty years.  The current economic downturn coupled with peoples’ desire to be more environmentally conscience, has brought about change in our perception of what a home should be.  Efficiency is the key word of today, and now more than ever, it is an integral part of designing and building a home.   Maximizing the efficiency of resources during construction can cut down home building costs, while quality construction and air-sealing a home can cut down the energy costs over its lifetime.

Here at SWA Architects, we have begun developing a housing design strategy that is built on the motto of efficiency.  We have started preliminary designs of homes that are designed to fit narrower suburban and urban lots and range in size from 1,800 to 2,500 square feet.  (more…)

Illinois Residential Energy Code Update

IECC

Without fanfare or articles in the mainstream media, the Energy Efficient Building Act became effective in Illinois on January 29, 2010 for most new residential construction in Illinois.  As mentioned in an earlier blog, Illinois Governor Patrick Quinn signed the new statewide residential energy code into law on August 28th 2009.  The delay between signing the law and its effective date has been the necessity to write the administrative rules.

The Energy Efficient Building Act adopts the requirements of the latest edition of the International Energy Code, currently the 2009 International Energy Conservation Code (IECC).  The requirements are statewide, with the exemption of a few communities such as the City of Chicago and approximately 30 other municipalities that had adopted the 2006 IECC prior to May 15th, 2009.  Apart from the exempted communities, no local municipality has the authority to mandate energy requirements less than or greater than the requirements of the 2009 IECC.

It’s likely that many architects, builders and code officials are not yet aware of the new residential energy code requirements.   Although SWA Architects has already been providing upgraded insulation packages for many of the homes we design, the new code will affect some of our details and specifications.

Going for Green: Part II

Design has wrapped up on the Green Home in Wheaton. SWA Architects and JAW Builders have worked together to devise a strategy for building what is planned to be an Emerald level certified home through the NAHB Green Building Program.

Home size is a key element when designing a home, and it is important to design a home that is appropriate for a families needs without adding unnecessary or excess space. At 3,600 square feet, the home is larger than what some would consider an ideal “green” designed home, but numerous factors, including the need for a home office, dictated the design. Limiting transition spaces such as halls and foyers to only what is needed helps create an efficient floor plan where living space is maximized. (more…)

Lighting and Lighting Controls

Architectural lighting is vital for merchandising, work space productivity and architectural enhancement. In recent years, there have been major innovations to both the light fixtures and lighting controls. The latest energy codes continue to restrict the amount of energy used for lighting in a building. Lighting controls are increasing in importance for achieving energy savings, especially in commercial applications where day lighting is used to reduce the intensity of artificial lighting. Reducing artificial lighting also reduces air conditioning loads as an additional benefit. The Lutron EcoSystem is an example of a commercial lighting control system using dimming ballasts for fluorescent fixtures coupled with occupancy sensors, photo sensors and day lighting to reduce lighting energy needs by 40% – 70%.

As for residential design, compact fluorescent lights (CFL) have become the universal solution as a replacement for the typical incandescent lamp for increasing (more…)
