The website offers green-building standards, codes, certification systems and tools to assist professionals to achieve LEED certification.
In US, Green building codes are established by law as mandatory building requirements adopted by a state or local jurisdiction. Adopted codes are often based on established standards, and “model” code language is developed by building compliance professionals with input from stakeholders. Currently, model codes are revised and updated on a continual basis an open, public forum where amendments are proposed, debated and voted upon. This is the only aspect that may impact policies.
Green building tools support building-codes by providing means to analyse specific aspects of sustainable or “green” building, such as energy efficiency modelling, indoor air quality analysis or materials screening and evaluation. These tools can be standards themselves, and are sometimes referenced in whole green building systems, codes and certification systems. Several tools referred to by some of the leading green building approaches are:
1. Whole building life cycle assessment: The Athena Impact Estimator
2. Energy efficiency: For residential buildings, the RESNET Standard for HERS (Home Energy Rating System)
Both of these aspects may influence the sustainability and energy policies.
Apart from that, the scope of several green building approaches available was highlighted based on building types;
a. Whole green building systems: American Society of Heating, Refrigeration, Air conditioning Engineers 189.1 (ASHRAE)
b. Green building codes: International Green Construction Code (IgCC)
c. Green building certification/rating systems: Leadership in Energy & Environmental Design (LEED), Green Globes, Living Building Challenge
2. Non-residential or commercial sectors
a. Whole green building systems: National green building standard (NGBS)
b. Green building certification: LEEDS HOMES
Industry misconceptions around high cost and poor market interest in energy efficient homes continue to obstruct the mass adoption of low carbon housing. Josh’s House demonstrates that low carbon housing is accessible and cost effective. The Star Performers series showcases how...Read more
A rapid review on green-rated office buildings, and their operational energy use, found that the conclusions of six studies ranged from the certified buildings performing worse, similarly or much better than the non-certified buildings in terms of energy usage intensity. Two...Read more
In response to feedback, high-income households can reduce their energy use to a larger degree than low-income households (17% vs 3% reduction). This and other insights were gained by two rapid reviews into research, both Australian and International, on digital services and...Read more
This paper quantifies the greenhouse gas (GHG) emissions co-benefits associated with water, waste and transportation usage in certified green commercial office buildings in California. The study compares the measured values of water, waste and transportation usage self-reported by office buildings certified under the Leadership in Energy and Environmental Design rating system for Existing Building Operations and Maintenance (LEED EBOM) to baseline values of conventional California office buildings.
First adopted in 2007, and most recently renewed in 2015, New Mexico’s Sustainable Building Tax Credit supports the greening of many building types across the state. Released in October, 2017, this case study captures the impacts of this landmark policy and highlights the context and people that helped to create and sustain this nation-leading green building policy.
This is an example of LEED being used in an innovative tax policy across the United States and potentially serve as a tax model elsewhere.
