Alternative Energy System’s team of qualified and experienced sustainability and green building professionals can provide LEED Certification Consulting services to help navigate and understand the LEED Certification process.

LEED, or Leadership in Energy and Environmental Design, is a third-party building performance measurement system from the US Green Building Council that provides building owners and operators with a framework for identifying and implementing practical and measurable green building design, construction, operations and maintenance solutions.

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. The LEED process involves quantifying all of the sustainable design attributes of a project, modeling the proposed energy and water consumption, and commissioning the buildings upon completion to verify delivery of a high-performance system for reduced environmental impacts.

Build-it Green/GreenPoint Rated Certification

GreenPoint Rated is a program of Build It Green, a professional non-profit membership organization whose mission is to promote healthy, energy and resource efficient buildings in California. GreenPoint Rated´s recommended measures and performance benchmarks specifically address climate and market conditions in California. They are recognized by third party sources, including the California Air Resources Board, the California Energy Commission and the Association of Bay Area Governments. Ratings are performed by certified GreenPoint Raters, independent professionals who are trained and certified by Build It Green. The rating process is a non-invasive physical examination of building systems, structures, materials and components to assess energy and water efficiency, indoor air quality, resource efficiency of materials and construction methods, and construction quality.

The rater will generally engage in at least four of the five following activities during the course of project design and construction: Plan Check, Rough Inspection, Final Inspection, Supporting Documentation Review, Performance Testing.

Alternative Energy Systems has extensive experience with the GreenPoint Rated system and requirements, and our team includes Certified Green Point Raters (CGPR).

The California Association of Building Energy Consultants (CABEC), a non-profit organization, was founded in 1986 to foster professional development and ethics in the field of energy compliance through sponsorship of educational programs for industry professionals on building energy efficiency. This includes a voluntary Certified Energy Analyst program, the Certified Energy Plans Examiner training and testing, a monthly electronic newsletter, web site, annual meetings and free regional meetings. These activities have been developed to assure a professional level of training, experience and qualification for those individuals preparing Title 24 compliance and energy analysis documentation.

In April 1995, the National Association of State Energy Officials and Energy Rated Homes of America founded the Residential Energy Services Network (RESNET) to develop a national market for home energy rating systems and energy efficient mortgages. RESNET’s activities are guided by a mortgage industry steering committee composed of the leading national mortgage executives.

CHEERS is California’s Energy Code (Title 24) Registry. The CHEERS Registry is a robust, cloud-based registration platform serving the California construction market. All building projects complying with California’s progressive Building Energy Code (Title 24) can register with CHEERS to show compliance for permit and building inspection purposes.

The CHEERS team includes software engineers, building scientists, rating professionals, and building code veterans who share a passion for energy efficiency within the building industry.

A Home Energy Rating System (HERS) is a process of administering diagnostic analysis to determine and produce data that provides a method of evaluation for a California State approved home energy efficiency ratings. This establishes a benchmark of a home’s energy use and identifies necessary and/or best possible upgrades for homeowners.

In 2003 CalCERTS, Inc. was approved by the California Energy Commission to become a Home Energy Rating System (HERS) Provider. The company’s mission is to fill the growing need in the Energy Efficiency industry for a technically superior, yet customer-oriented HERS Provider. CalCERTS, Inc. is a private organization that provides service, support, training and certification to HERS raters.

ENERGY STAR is a dynamic government/industry partnership that offers businesses and consumers energy-efficient solutions, making it easy to save money while protecting the environment for future generations.

In 1992 the US Environmental Protection Agency (EPA) introduced ENERGY STAR as a voluntary labeling program designed to identify and promote energy-efficient products to reduce greenhouse gas emissions. Computers and monitors were the first labeled products. Through 1995, EPA expanded the label to additional office equipment products and residential heating and cooling equipment. In 1996, EPA partnered with the US Department of Energy for particular product categories. The ENERGY STAR label is now on major appliances, office equipment, lighting, home electronics, and more. EPA has also extended the label to cover new homes and commercial and industrial buildings.
