The 2010 edition of ANSI/ASHRAE Standard 55 combines Standard 55-2004 and the ten approved and published addenda to the 2004 edition into one easy-to-use, consolidated standard. The standard outlines conditions for environmental thermal acceptability. It is intended for use in design, commissioning, and testing of buildings and other occupied spaces and HVAC systems and for the evaluation of thermal environments.

New updates to the standard include extended provisions for evaluating the impacts of elevated air speed, a new method for expressing and selecting air speed limits, and alternatives for determining the boundaries of comfort at air speeds above 0.15 m/s (30 fpm). It continues to focus on defining the range of indoor thermal environmental conditions acceptable to a majority of occupants, while accommodating an increasing variety of design solutions intended to both provide comfort and to respect today’s imperative for sustainable buildings.

Section 6, Compliance, contains new mandatory minimum requirements for analysis and documentation of a design, and a new general satisfaction survey has been added as a method to evaluate thermal comfort in occupied spaces. The committee has also made significant editorial improvements to the comfort zone graphic and clarified requirements to avoid informative language.

Standard 90.1 has been a benchmark for commercial building energy codes in the United States and a key basis for codes and standards around the world for more than 35 years. This standard provides the minimum requirements for energy-efficient design of most buildings, except low-rise residential buildings. It offers, in detail, the minimum energy efficiency requirements for design and construction of new buildings and their systems, new portions of buildings and their systems, and new systems and equipment in existing buildings, as well as criteria for determining compliance with these requirements. It is an indispensable reference for engineers and other professionals involved in design of buildings and building systems.

This 2016 edition comprises numerous energy-saving measures and incorporates changes from more than 125 addenda. It also includes the following:

Format changes to improve usability and readability:

  • One-column format for easier reading
  • Exceptions separated, indented, and set apart with a smaller font size
  • Italicized defined terms
  • Changes to table formats to provide contrast between rows

Structural changes:

  • A new Reference Standard Reproduction Annex 1 is provided at the end of the document. Section 5.1.4 now cites ASHRAE Standard 169 as the source for climatic data, and Annex 1 contains extracts of tables and figures from that standard for the readers convenience.
  • Two new climate zones (0A/B) have been added to all prescriptive requirements tables.

Significant technical content changes:

Building Envelope

  • Envelope verification in support of reduced air infiltration and increased requirements for air leakage of overhead coiling doors.
  • Increased stringency requirements for metal building roofs and walls, fenestration, and opaque doors.
  • Improved clarity on defining exterior walls, building orientation, fault assumptions for the effective R-value of air spaces, and calculation procedures for insulating metal building walls.

Lighting

  • Modified requirements for exterior and interior lighting power densities to reflect new lighting levels in the IES Lighting Handbook.
  • Modified requirements for lighting control to add additional controls in some space types and options to others to allow easier application of advanced controls.

Mechanical

  • Large, electrically driven chilled-water plants are now required to be monitored for electric energy use and efficiency.
  • Dedicated outdoor air systems now include both efficiency and rating requirements for compliance.
  • Requirements are introduced for designs to include both use category and efficiency class.
  • Requirement that air-cooled DX cooling units with economizers have a monitoring system to determine that the air economizer is working properly.

Energy Cost Budget (ECB) and Modeling

  • Appendix G now can be used as a path for compliance with the standard.
  • Changes to elevator, motor, and refrigeration baselines; changes to the baseline for existing building projects; and changes to specific opaque assemblies for the baseline envelope model. Modeling rule changes were made to heat pump auxiliary heat, economizer shutoff, lighting controls, humidification systems, cooling towers, and the simulation of preheat coils.

ASHRAE Standard 188 establishes minimum legionellosis risk management requirements for building water systems.

Included in this publication are: description of environmental conditions that promote the growth of Legionella and informative annexes and an bibliography that contain suggestions, recommendations, and references to additional guidance.

In addition, content throughout the document is revised to bring it in line with current technical standards. Standard 188 is essential for anyone involved in design, construction, installation, commissioning, operation, maintenance, and service of centralized building water systems and components.

This is a Spanish translation of ASHRAE Standard 189.1-2011, Standard for the Design of High-Performance Green Buildings.

The purpose of this standard is to provide minimum requirements for the siting, design, construction, and plan for operation of high-performance green buildings to (a) balance environmental responsibility, resource efficiency, occupant comfort and well being, and community sensitivity, and (b) support the goal of development that meets the needs of the present without compromising the ability of future generations to meet their own needs.

This standard provides minimum criteria that:

  • apply to the following elements of building projects:
    1. new buildings and their systems
    2. new portions of buildings and their systems
    3. new systems and equipment in existing buildings
  • address site sustainability, water use efficiency, energy efficiency, indoor environmental quality (IEQ), and the building’s impact on the atmosphere, materials, and resources.

The provisions of this standard do not apply to single-family houses, multi-family structures of three stories or fewer above grade, manufactured houses (mobile homes) and manufactured houses (modular), or buildings that use none of the following: electricity, fossil fuel, or water. This standard is a compliance option of the International Green Construction CodeTM (IgCCTM).

Keywords: sustainable, green, energy, indoor environmental quality, IEQ, green standard, green building, 189.1, 189, high performance building, high-performance building, LEED, TC 2.8, IES, USGBC, IGCC, Spanish
