According to the JCI release, with the transition to R-454B refrigerant transition "we will exceed key regulatory requirements and also take a significant step toward reaching one of our ambitious sustainability benchmarks: helping our customers achieve a 16 percent reduction in emissions by 2030."
R-454B has the lowest EPA SNAP approved GWP for unitary applications of all ASHRAE classified A2L (low-toxicity, mild flammability) refrigerants on the market today, coming in at 466 -- one-fifth the GWP of R-410A, far lower than the pending 750 GWP limits being proposed and offering the longest-term viability. In addition, the refrigerant can reduce the energy use of HVAC systems and improve system efficiency.
The transition to R-454B will apply only to the sale of new air-cooled scroll chillers by the pending manufacturing cutoff date of January 1, 2024, and residential and commercial unitary products by the pending manufacturing cutoff date of January 1, 2025, for the following brands: Johnson Controls, YORK, Luxaire, Coleman, Champion, Fraser-Johnston, TempMaster,, Evcon,, Guardian and Quantech. Existing R-410A equipment manufactured prior to the manufacturing cutoff dates can be sold, installed and serviced indefinitely.

META grants are used by Massachusetts municipalities, regional school districts, and water/wastewater districts to aid in the management of projects or the performance of studies to support the development of clean energy and energy efficiency in the Commonwealth. Open to all 351 cities and towns, META grants fund the services of expert consultants and contractors to assist with a diverse array of local energy projects.
Projects and studies receiving funding will support the performance of solar photovoltaic site evaluation, heating system replacements, ASHRAE Level II audits, technical analysis of energy use at drinking water and wastewater facilities and technical assistance with efficient building planning, maintenance, and operation. Part of DOER's Green Communities Division, the grants are funded through proceeds from the Regional Greenhouse Gas Initiative (RGGI).
Under the Green Communities Act, cities and towns must meet five criteria to be designated a Green Community and receive funding. 271 Bay State cities and towns accounting for 84 pct of the state's population have earned the Green Communities designation.

Delaware first established a minimum statewide code for energy conservation in 1979. The code, which is based on standards set by the International Code Council (ICC) and the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHREA) was last updated in 2009.
The update includes a six-month transition period, during which the Division of Climate, Coastal and Energy will provide targeted training and technical assistance to the construction industry and code enforcement officials. Topics covered by the training will include an overview of the changes, practical compliance strategies, particularly for the building envelope requirements in the new energy codes, construction and design strategies for air sealing smaller homes, and hot water pipe insulation and HVAC duct design.

The State code is based on the 2018 International Energy Conservation Code and ASHRAE Standard 90.1-2016. The 2020 NYCECC will become effective May 12, 2020, the same effective date as the state's energy code which aligns the code with the New York State Energy Research and Development Authority (NYSERDA) NYStretch Energy Code-2020, as adopted by the New York City Council on March 29, 2020.
The 2020 New York City Energy Code includes energy efficiency requirements help to improve overall building envelope performance through installation of better performing and more energy efficient windows and other initiatives.

The changes add new and lengthy steps to the procedure used in updating existing or developing new energy efficiency standards include:
The previous Process Rule, which was climate-friendly, would help in reducing carbon emissions and saved the average US household $500 per year. The Trump administration claims the revealed Process Rule will save consumers about $2 trillion by 2030.
According to ACEEE Exec. Dir. Steven Nadel, "These attacks defy the common-sense, bipartisan support that energy efficiency has long enjoyed.
They will cost consumers and businesses money, create market uncertainty for businesses due to likely legal challenges, add to harmful pollution, and undermine efforts to address the climate crisis."

Standard 90.4 applies to data centers with a conditioned floor area greater than 20 W/ft2 and IT equipment loads greater than 10 kW and contains specific requirements for mechanical and electrical systems installed in new data centers or in data center additions/alterations that require new mechanical or electrical systems. Updates to the standard include:
Alongside Built Green's Single Family Renovation Program, also applicable to multi-family low rise, the High Density (HD) Renovation Program offers builders a means to renovate high density and high density mixed-use buildings more sustainably.
To qualify for the HD Renovation program, substantial upgrades/retrofits must be made to the energy-related building systems, including the building envelope and the mechanical and electrical systems. The energy performance of the building's upgrades and retrofits are then compared to the requirements of the current energy standard or energy code used for modeling with ASHRAE 90.1-2010 or NECB 2011 to show energy savings resulting from the renovation. Beyond efficiency, the renovations must be sustainable.
Strategic Group has four high density renovation projects enrolled in this pilot. Additionally, the company has two projects enrolled in Built Green High Density New Construction, while yet another project was certified in 2017.
Built Green Canada is a national, industry-driven, not-for-profit organization offering third-party certification programs in the residential building sector. Since its inception, builders have completed over 32,750 BUILT GREEN® certified homes in Alberta, British Columbia, Saskatchewan, and Ontario; including units in multi-storey projects, this total is over 36,090 (as at March 31, 2019).

Section 179D of the tax code offers a tax deduction to building owners and businesses for energy efficiency improvements such as lighting, heating and cooling, hot water systems, ventilation, or the building envelope like insulation or windows. It offers incentives for upgrades at new or existing buildings that cut the total energy and power cost by at least 50 percent compared to a building meeting the ASHRAE codes baseline for energy efficiency.
Jason Hartke, CEO, Alliance to Save Energy states, "This is a key tax incentive for encouraging energy efficiency in commercial buildings, which account for about 20 percent of U.S. energy consumption. It is important that Congress extend this incentive to give building owners and designers the certainty they need to make these investments." (Source: Office of Rep.

The 2018-IgCC update will help governments streamline code development and adoption, and improve building industry standardization by combining the technical requirements developed by the ASHRAE Standard 189.1 with the model code administrative provisions by the Code Council. As a result, the 2018-IgCC is now a unified code that emphasizes adoption, ease of use and enforcement for building projects.
The IgCC is a part of the Code Council's suite of comprehensive, coordinated and contemporary model codes -- including the International Building Code, International Existing Building Code, International Energy Conservation Code, International Mechanical Code, International Plumbing Code and International Fire Code -- and is suitable for use in building codes world wide.

According to the AEA, nonresidential buildings consume more than half the building energy use in Alaska, and the majority of these buildings are privately owned. The Commercial Building Energy Audit program is designed to pay up to 75 pct of the cost of an ASHRAE level 1+ energy audit performed on privately owned commercial buildings. The audit cost is set by the building size and ranges from $600 for buildings up to 3,000 square feet up to $2,100 for buildings over 20,000 square feet.
The AEA reports that results of past similar programs indicate average energy savings of roughly 1/3 resulting from economic efficiency investments with average simple paybacks of just over six years.
