New Energy Saving Calculator for Airtight Building Design

Lido Beach Towers in Long Island, N.Y., a condominium community, used air moisture barriers in a resilient design retrofit that resulted in energy savings of up to 33 percent as well as enhanced structural protection.

The Air Barrier Association of America (ABBA), in conjunction with Oak Ridge National Laboratories (ORNL) and the National Institute of Science and Technology (NIST) have developed a web based energy saving calculator for building airtightness. This valuable new resource will help the building industry quantify energy savings based on the use of air barriers that increase the airtightness of buildings.

We all know that uncontrolled heat, air, and moisture transfer through a building envelope has a significant impact on energy usage. A comprehensive strategy for concurrently regulating these factors can have a major impact on reducing energy consumption. Air moisture barriers (AMBs) have proven to be effective and economic but now these benefits can be better calculated in advance.

The hope is that there will be wider adoption of air barrier systems in building design thanks to this simple and credible tool that can be employed by architects, designers, and owners to accurately estimate anticipated energy savings if an air barrier system is added to the design. This new energy saving calculator is based on the best science available, it’s easy to use, available to everyone, and best of all – it’s free.


New Web-based Tool for Energy Efficiency Project Financing

New financing navigator facilitates funding for energy efficient building.

The U.S. Department of Energy (DOE) has introduced a new web-based financing navigator to help private and public sector organizations understand and access financing solutions available for energy efficiency building projects.

Since limited financing options are often cited as a major barrier to investing in energy efficient systems, the “Better Buildings Financing Navigator”  now offers building owners, facility and energy managers, and other decision-makers guidance on how to connect with investors and lenders  so that they can pursue energy-saving projects. By bringing smart financing solutions to the market, building construction and management teams can move forward more rapidly with energy efficiency refits and upgrades.

The DOE’s financing navigator helps users identify relevant financing options which are tailored to their needs and also provides technical research and advice. The site encourages collaboration between public and private sector organizations across the country to share and replicate successful strategies with the goal of making commercial, public, industrial and residential buildings 20 percent more energy efficient over the next decade. This potentially means saving billions of dollars on energy bills, while accelerating America’s investments in energy infrastructure and creating thousands of jobs.


Passive Design Projects Worldwide Drive Global Energy Savings

Heidelberg Village in Germany will be the largest residential Passive Design project in the world.

Touted as “the world’s largest passive housing” project, a 162 unit residential complex is currently under construction in Heidelberg, Germany. The solar-powered Heidelberg Village designed by the Frey Architekten firm will feature a wide range of sustainable features, as well as rooftop and vertical gardens. The complex is expected to use 75% less energy than a similar project using conventional building design.

The Passive design concept originated in Germany in the 1990’s, and has now been embraced worldwide as an effective and economic way to cut carbon emissions and reduce energy demand in buildings while still providing high-caliber living comfort, superior indoor air quality and structural resilience. While the movement began with a residential focus, passive “house” building principles have been adopted in major commercial building projects as well, setting new standards for heating and cooling efficiency, total energy consumption and air leakage.

One of the most ambitious “passive design” commercial projects currently underway is in Belgium where Europe’s largest passive office complex is under construction. The Herman Teirlinch government office will be a 66,500 square meter mixed use, low-rise, sustainable building designed by Neutelings Riedijk.

While entire passive home neighborhoods have yet to be created in the United States, passive design residential and commercial buildings are cropping up nationwide. The key components are 1) high-quality insulation and thermal-bridge-free construction 2) airtight construction 3) energy efficient windows and doors 4) mechanical ventilation for air quality.

Sto Corp has been a leader in providing passive design projects with energy efficient exterior insulation and finish systems. StoTherm ® ci continuous insulation, air moisture barriers, and advanced wall cavity systems have been used to meet and even exceed passive design energy efficiency standards in various climate zones across the country.

PACE Spurs Building Upgrades for Energy Savings

Now there's financing available to cut energy waste in buildings of all types and sizes.

PACE, which stands for Property Assessed Clean Energy, is a simple and effective mechanism for financing energy-efficiency retrofits and renewable energy upgrades that might not otherwise be affordable for commercial, residential, industrial, and agricultural buildings. PACE financing overcomes the upfront cost barrier these upgrades can pose by providing 100% of the financing for such projects.

The financing is paid back via property tax assessments that can stretch as long as 20 years. In most instances, the related energy savings more than pay for the assessment. Through the use of innovative PACE funding, new energy-efficient heating and cooling systems, insulation, solar and lighting improvements can be immediately rendered cash flow positive.

PACE funding has soared, as owners recognize the opportunity to increase their bottom line by reducing energy costs, to enhance the value of their property and do their part to offset greenhouse gas emissions. Since three quarters of the electricity generated in America is used to heat, cool, illuminate, and otherwise operate buildings, it’s not surprising that Scientific American magazine named PACE one of 20 “world changing” ideas.

Energy Efficient Buildings Key to Combating Climate Change

energy efficient building

Renovating the Federal Building in Portland, Oregon cut energy usage by 45% and water consumption by 60%.

A new report from the U.S. Green Building Council and the American Sustainable Business Council concludes that energy-efficient buildings are one of the most effective and economical ways to reduce the nation’s carbon footprint in response to global warming. That’s because buildings account for more greenhouse gas emissions in the U.S. than any other source, including transportation and industry. The report probes the economics of green buildings and their value in mitigating greenhouse gas production, suggesting that brick and mortar solutions to the climate challenge make for good economics in the long run.
