See More Minutes Project Committee meeting minutes are available to interested parties upon written request of the Manager of Standards. Decisions to distribute attachments to the minutes will be made on a case by case basis and due to the size of the request may take longer to process. Title, Purpose, and Scope Standard for the Design of High-Performance, Green Buildings Except Low-Rise Residential Buildings 1 Purpose: 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.

Performance path: A proposed building design is demonstrated through building performance simulation to use less energy than a baseline building built to ASHRAE This now has three paths. For code compliance there is Chapter 11, which compares an energy model for your building to an energy model for a barely compliant building with the same HVAC system and in the edition an Appendix G path was added that compares an energy model of your building against a baseline model based on the edition of Standard Within the sections of the standard, there are some variations to this.

Some sections have mandatory provisions, simplified approaches, or trade-off opportunities. This baseline ECB is established using building performance simulation to model a building with the same size and program as the project building, built according to the prescriptive requirements of ASHRAE The ECB is expressed in units of dollars.

A building performance simulation is then performed on the proposed building design. The proposed energy cost budget must be less than or equal to the baseline energy cost budget to achieve compliance. The performance approach is also used to demonstrate design energy efficiency, often expressed as percent better than ASHRAE Standard Most states apply the standard or equivalent standards for all commercial buildings.

Others apply the standard or equivalent standards for all government buildings. There are some states that use other energy conservation standards for all commercial buildings and some other states that use a combination of the ASHRAE A few states do not apply any energy conservation standards for their government and commercial buildings.

It is frequently used as a baseline for comparison during energy retrofit projects or any project that employs building performance simulation. A draft of the standard was issued on June 21, , to 5, industry stakeholders for public review.

New buildings being constructed and the systems that run the new buildings would be covered by the standard. The standard would also apply to additions to existing buildings and their systems as well as alterations to an existing buildings system. Each one has different requirements to meet. There are also mandatory provisions that building envelopes have to abide by which are insulation, fenestration and doors, and air leakage.

Each section of the building envelope, Roof, Walls, and Floor have different requirements for each of the mandatory provisions. This is because there are many types of HVAC systems each with different requirements. The HVAC section has the most requirements because there are so many different types of systems. There are systems that can not be used and things that systems must have to meet the requirements. Each system must meet the manufactures sizing guidelines.

The pipes that hold the hot water need to be insulated and there are certain insulation requirements for each system type and piping material. There are many controls that hot water systems need and each control has a different requirement. These include are temperature controls, temperature maintenance controls, outlet temperature controls, and circulation pump controls.

There are also requirements for pool heaters, pool covers, and heat traps for heated pools. Lighting also has many requirements to follow, which includes the prescriptive requirements to determine the quantity of lights for the building.

There are also interior lighting controls that need to be installed for buildings larger than sqft. There are also many requirements on lighting that include exit signs and exterior lights. Energy savings compared to DOE issued a positive determination and notified states that they should adopt The scope was expanded to include defined industrial processes, which in the edition includes only economizers for data centers.

Changes to Building Envelope include skylights, solar reflectance, thermal emittance, air barriers, and solar orientation.

Minimum efficiency requirements for many types of HVAC equipment were revised. Other revisions affect the maximum fan power limits, pump head calculation, chilled water pipe sizing, radiant panel insulation, single-zone VAV, and supply air temperature reset. Energy recovery is required for many more HVAC systems. Several reheat exceptions were eliminated or modified. Restrictions were placed on overhead air heating.

Economizer requirements were added for more climate zones and smaller systems. Class A is now required for all duct sealing. Lighting power densities LPD dropped slightly on average. Daylighting and associated lighting control requirements were added.

Many lighting control requirements were added, including independent functional testing of lighting controls, occupancy and vacancy controls, exterior lighting controls, and whole-building shutoff. Requirements were added for service water booster pumps and elevators. Ashrae standard Department of Energy, Initials.
