Energy Performance Standards
A Passive House is the most stringent building energy standard in the world. Buildings that meet the Passive House standard use 80% less energy than conventional buildings. A Passive House conserves energy by creating a virtually air-tight, super insulated, compact building envelope that uses the sun and internal gains to achieve space conditioning. A heat recovery ventilator (HRV) is used to condition extract air and provide superior indoor air quality. A Passive House can achieve zero energy building energy standard with the use of a small renewable energy system. Richard Pedranti is a Certified Passive House Consultant (CPHC).

US Department of Energy (DOE) Builders Challenge
The U .S. Department of Energy’s (DOE) Builders Challenge and the Energy Smart Home Scale SM (E-Scale) help homebuyers find architects who design the most efficient homes in the nation. The E-Scale allows buyers to understand how the energy performance of one home compares with others. Combining years of research with the work of the nation’s leading builders, under the DOE’s Building America Program, the goal is that by 2030 new homebuyers will have the option to purchase a cost neutral Net-Zero Energy Home (NZEH) anywhere in the United States.
US Department of Energy (DOE) Energy Star
ENERGY STAR is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy helping us all to save money and protect the environment through energy efficient products and practices. To earn the ENERGY STAR rating, a home must meet strict guidelines for energy efficiency set by the U.S. Environmental Protection Agency. These homes are at least 15% more energy efficient than homes built to the 2004 International Residential Code (IRC), and include additional energy-saving features that typically make them 20–30% more efficient than standard homes. Richard Pedranti Architect is an Energy Star partner.
2009 International Energy Conservation Code (IECC)
The 2009 International Energy Conservation Code (IECC) is the current version of the International Code Council energy conservation code that is widely adopted by federal, state, and local governments.
EPA Indoor airPLUS
The U.S. Environmental Protection Agency (EPA) created Indoor airPLUS to help architects meet the growing consumer preference for homes with improved indoor air quality. The EPA developed additional construction specifications to help improve indoor air quality in new homes. Construction specifications include the careful selection of and installation of moisture control systems; heating, ventilating, and air-conditioning systems; combustion-venting systems; radon resistant construction; and low-emitting building materials. An architect must first design a home to earn the Energy Star label. Before the home officially earns the Indoor airPLUS label, it is inspected by an independent third-party to ensure compliance with EPA’s rigorous guidelines and specifications. Richard Pedranti Architect is an EPA Indoor airPLUS partner.
Home Energy Rating System (HERS index)
The HERS Index is a scoring system established by the Residential Energy Services Network (RESNET) in which a home built to the specifications of the HERS Reference Home (based on the 2004 International Energy Conservation Code) scores a HERS Index of 100, while a net zero energy home scores a HERS Index of 0. The lower a home's score, the more energy efficient it is in comparison to the HERS Reference Home. Each 1-point decrease in the HERS Index corresponds to a 1% reduction in energy consumption compared to the HERS Reference Home. Thus a home with a HERS Index of 85 is 15% more energy efficient than the HERS Reference Home and a home with a HERS Index of 80 is 20% more energy efficient.
Leadership in Energy and Environmental Design (LEED)
Developed by the United States Green Building Council (USGBC), LEED certification is a point based system for achieving green building. LEED certification provides independent, third-party verification that a building, home or community was designed and built using strategies aimed at achieving high performance in key areas of human and environmental health: sustainable site development, water savings, energy efficiency, materials selection and indoor environmental quality. Certification occurs through the Green Building Certification Institute (GBCI), an independent non-profit that was established in 2008 with the support of USGBC. GBCI includes a network of ISO-compliant international certifying bodies, ensuring the consistency, capacity and integrity of the LEED certification process. Richard Pedranti Architect is a member of the USGBC and Richard Pedranti is a LEED accredited professional BD+C.
Architecture 2030 Challenge
The Architecture 2030 Challenge is an initiative by Architect Edward Mazria and Architecture 2030 asking the global architecture and construction community to adopt a series of greenhouse gas reduction targets for new and renovated buildings. These targets may be accomplished by implementing innovative sustainable design strategies, generating on-site renewable power and/or purchasing (20% maximum) renewable energy. Richard Pedranti Architect is an adopter of the 2030 Challenge.
Zero Energy Building (ZEB)
A zero energy building (ZEB), also known as a zero net energy (ZNE) building, Net-Zero Energy Building (NZEB), or Net Zero Building, is a popular term to describe a building with zero net energy consumption and zero carbon emissions annually. Energy is first reduced through conservation with building design strategies such as super insulation of the building envelope, high efficiency equipment, and passive solar design. The remaining energy requirements can be harvested on-site usually through a combination of renewable energy technologies such as photo-voltaic, solar thermal, wind.
Deep Energy Retrofit
A deep energy retrofit is the renovation of an existing building that achieves a minimum of 50% reduction is energy consumption. The goals of a deep energy retrofit are similar to building a new green building. Energy conservation is achieved through improving the energy performance of building envelope, installing high efficiency equipment and lighting, and installing renewable energy systems such as photovoltaic and solar thermal.
Zero Fossil Fuels
Zero fossil fuels are achieved by designing a building without the consumption of fossil fuels on site.
