Existing Building Energy Consumption: Current Situations, Trends, Legislature and Solutions (Series Post #4: ASHRAE)

American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) is accredited by the American National Standards Institute (ANSI) and follows ANSI’s requirements for due process and standards development. ASHRAE has helped to mainstream the integrity of commissioning by setting guidelines and criteria for the commissioning process. ASHRAE has also partnered with the United Nations Environment Program to drive their global effort in reducing the amount of pollutants released into the atmosphere by buildings. ASHRAE has created an international advisory team to assist developing countries in their goals to institute and revamp relevant codes and standards.

In terms of building commissioning and retro-commissioning, ASHRAE developed Guideline 0 – Commissioning Process and Guideline, which details the process, intent, activities and deliverables that should be followed to optimize benefits. This document has incited the development of numerous supporting guidelines and standards for the commissioning process. In addition, ASHRAE also defined best practices and created different levels of energy audits (Preliminary Analysis, Level 1, 2 and 3).  If you are interested in learning more about these guidelines, visit ASHRAE’s website (https://www.ashrae.org). In particular, they have posted their Fall 2013 online courses here: https://www.ashrae.org/education–certification/2013-fall-online-courses. On October 9th there is a Commissioning for High Performance Buildings course and on November 4th and 6th there is a Commercial Building Energy Audits course.

As part of the PlaNYC initiative to have a more sustainable New York City, all buildings over 50,000 sf are required to file an Energy Efficiency Report (EER) with the New York City Department of Buildings (NYC DoB). This requirement is known as Local Law 87. The EER consists of an ASHRAE Level II energy audit and retro commissioning study of base building systems. Base building systems include systems or subsystems that use energy or impact energy consumption, including: building envelope, HVAC systems, conveying systems, domestic water systems and electrical/lighting systems. EERs are due to the NYC DoB once every 10 years starting this year. The EER reports are due in a staggered schedule, which is based on the last digit of the building’s tax block number.

Do you have any questions regarding ASHRAE and how they are involved with Local Law 87 legislature? Post them in the comments below. In my next blog, I will provide an overview of the second part of Local Law 87 compliance, retro-commissioning.

  1. Local law 87 nyc has been a great initiative and have been in full effect since it was launched. The complied data of energy use of the buildings will help to analyze the consumption and ways to waste less energy to save the extra expenditures.
