Energy Standard for Buildings

“Student Painting Competition” (2013) / Rida Maryam Qureshi United States Agency for International Development

The American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) is an ANSI-accredited continuous-maintenance standards developer (a major contributor to what we call a regulatory product development “stream”).   Continuous maintenance means that changes to its consensus products can change in as little as 30 days so it is wise to keep pace.

ASHRAE has released another batch of candidate changes to its flagship product — ASHRAE 90.1 Energy Standard for Buildings Except Low-Rise Residential Buildings — all of which affect the design, construction and operation of education facilities because they are heavily referenced in local, state and federal energy legislation.   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.  Free access to ASHRAE 901. is available at the link below:

READ-ONLY Version of 2016 ASHRAE 90,1

Four redlines were recently released by the ASHRAE 90.1 committee:

Addendum b: Demand Controlled Ventilation (DCV) should be required when cost-effective for occupied spaces considering the required outside air for ventilation required based on number of people in the space,
varying space sizes, use of energy recovery equipment, and climate zone.

Addendum d: Tightening requirements for garage ventilation

Addendum i: Proposes changes to Exhaust Air Heat Recovery systems in laboratories

Addendum k:  Regarding budget building fan power to avoid a fan power credit for cases where the proposed building includes heat recovery and the budget building does not include heat recovery.

Comments due July 19th.

Sustainability Accounting Standards Board

 

Hercules Second Labor / Tufts University Perseus Digital Library

Time for a look at best practice literature emanating from the Sustainability Accounting Standards Board (SASB) — one of the first names in organizations with a solid due process platform for leading practice discovery and promulgation of sustainability concepts for the private sector.   Like the sustainability zietgeist itself; its topical areas are hydra-like — reaching into every sector, industry, and industry subsector — largely because money flows through all of them.

We classify the SASB suite as an open-source, consortia standards suite that challenges niche verticals.    Since the education industry has both a private and public revenue character, we follow SASB standards development and participate in proposal and commenting opportunities whenever possible.

Last year we selected six sector-specific SASB standards that, in our judgment, could lower #TotalCostofOwnership with improved management of sustainability advancement activity (See list below).   We downloaded these standards, looked them over for actionable-specifics, but we did not submit comments of our own because of organizational changes we explain in our ABOUT and also because we could not find an individual institution or education industry trade association interested in collaborating with us on meaningful specifics.  We will try again.

Until we find a collaborator you may be enlightened by the current status of the SASB suite; all of its products available to the public:

At the moment two developments at the SASB are meaningful for sustainability professionals in both the private and public sector:

Note that SASB standards setting committees last month and posted a comprehensive report on its activity:

Its oversight board meets on June 23rd, details below:

Standards Board Meeting Agenda: June 23, 2020

We encourage technical and business subject matter experts in education communities to try not to re-invent the wheel in developing sustainability policy templates but rather to collaborate with organizations whose existing consensus products can be adapted for education communities.   Perhaps post-pandemic, some of the redundancies we have been reporting to the education facility industry will be sun-setted.

We maintain the SASB suite on the standing agenda of our Finance teleconferences.  See our CALENDAR for the next online teleconference; open to everyone.   Use the login information at the upper right of our home page.

Today at 11 AM EDT we sweep through action in the consensus products that set the standard of care for mechanical engineering design, construction operations and maintenance. Mechanical systems — which, in our user-interest advocacy includes building service engineering* — can run upwards of 35 percent of new building construction.    The requirements that affect cost change on a near-daily basis so it is wise to keep pace with the action of technical committees worldwide.    Note that we co-locate plumbing and mechanical system consensus products in the same group.

Architects, engineering, facility planning and design units within academia are welcome to join us.  You will likely want to tweak your design guidelines and construction specifications (or be ready to make changes when automatic incorporation by reference make these codes and standards public law.  At the very least, time spent with us today offers anticipatory intelligence about technical specifics but also action by government agencies at all levels.

Our algorithm tracks action in the following list of accredited standards developers whose products are frequently found in plan drawings, specifications and operating and maintenance manuals:

AHRI | Air Conditioning, Heating & Refrigeration Institute

AIHA | American Industrial Hygiene Association

ASHRAE | American Society of Heating & Refrigeration Engineers

ASME | American Society of Mechanical Engineers

ASPE | American Association of Plumbing Engineers

ASTM | American Society for Testing & Materials

* Building services engineers are responsible for the design, installation, operation and monitoring of the technical services in buildings (including mechanical, electrical and public health systems, also known as MEP or HVAC), in order to ensure the safe, comfortable and environmentally friendly operation. Building services engineers work closely with other construction professionals such as architects, structural engineers and quantity surveyors. Building services engineers influence the architectural design of building, in particular facades, in relation to energy efficiency and indoor environment, and can integrate local energy production (e.g. façade-integrated photovoltaics) or community-scale energy facilities (e.g. district heating). Building services engineers therefore play an important role in the design and operation of energy-efficient buildings (including green buildings, passive houses and zero energybuildings.  uses. With buildings accounting for about a third of all carbon emissions] and over a half of the global electricity demand, building services engineers play an important role in the move to a low-carbon society, hence mitigate global warming.

Performance Monitoring for Power Plants

“A View of Murton Colliery near Seaham, County Durham” (1843) / John Wilson Carmichael

The American Society of Mechanical Engineers (ASME) has registered a Project Initiation Notification with ANSI to launch a revision to its consensus product ASME PM-202x, Performance Monitoring for Power Plants.  This product should interest stakeholders in involved in college and universities with district energy plants — facility management staffs, consulting engineers, operations and maintenance staff.

From the project prospectus:

These Guidelines cover fossil-fueled power plants, gas-turbine power plants operating in combined cycle, and a balance-of-plant portion including interface with the steam supply system of nuclear power plants.  They include performance monitoring concepts, a description of various methods available, and means for evaluating particular applications.

Since the original publication of these Guidelines in 1993—then limited to steam power plants—the field of performance monitoring (PM) has gained considerable importance.  The lifetime of plant equipment has been improved, while economic demands have increased to extend it even further by careful monitoring.  The PM techniques themselves have also been transformed, largely by the emergence of electronic data acquisition as the dominant method of obtaining the necessary information.

These Guidelines present:

• “Fundamental Considerations”—of PM essentials prior to the actual application, so you enter fully appraised of all the requirements, potential benefits and likelihood of tradeoffs of the PM program. 

• “Program Implementation”—where the concepts of PM implementation, diagnostics and cycle interrelationships have been brought into closer conjunction, bringing you up-to-date with contemporary practice.

• “Case Studies / Diagnostic Examples”—from the large amount of experience and historical data that has been accumulated since 1993.

Intended for employees of power plants and engineers involved with all aspects of power production.

From ANSI’s PINS registry:

Project Need: This document is being developed in order to address performance monitoring and optimization techniques for different power generating facilities. The latest trends and initiatives in performance monitoring as well as practical case studies and examples will be incorporated.

Stakeholders: Designers, producers/manufacturers, owners, operators, consultants, users, general interest, laboratories, regulatory/government, and distributors.

This document will cover power generation facilities including steam generators, steam turbines, and steam turbine cycles (including balance of plant of nuclear facilities), gas turbines, and combined cycles. The guidelines include performance monitoring concepts, a description of various methods available, and means for evaluating particular applications.

No comments are due at this time.   The PINS announcement was placed on October 11th*.   The PINS registry is a stakeholder mapping platform that identifies the beginning of a formal process that may interest other accredited, competitor standards developers.   Many ASME consensus products may be indirectly referenced in design guidelines and construction contracts with the statement “Conform to all applicable codes”

State Energy Codes

 

Highlandtown Community Association / US Congressional High School Art Competition

The U.S. Department of Energy (DOE) has reviewed the 2018 edition of the International Energy Conservation Code and determined the updated edition would improve energy efficiency in buildings subject to the code compared to the 2015 edition.

Final Determination Regarding Energy Efficiency Improvements in the 2018 International Energy Conservation Code

DOE analysis indicates that buildings meeting the 2018 IECC (as compared with buildings meeting the 2015 IECC) would result in national site energy savings of 1.68 percent, national source energy savings of 1.91 percent, and national energy cost savings of approximately 1.97 percent of residential building energy consumption. Upon publication of this affirmative determination, each State is required by statute to certify that it has reviewed the provisions of its residential building code regarding energy efficiency, and made a determination as to whether to update its code to meet or exceed the 2018 IECC. Additionally, this notice provides guidance on state code review processes and associated certifications.

Comments are due December 10, 2021
