Presented by the AIARE Committee on the Environment (COTE)

During this site tour in downtown Santa Rosa, we will follow the plumbing from the service entrance through the water heater and on to the locations of the plumbing fixtures and appliances at key locations in the building. We will examine the implications of the fitting choices and locations on the pressure loss in each distribution system and we will assess the time-to-tap and volume-until-hot based on the layout of the hot water piping. We will also discuss what we see in the mechanical room(s) including the water heating system. The implications of the system choices for the workers’ and occupants’ health and welfare will be addressed.

Personal Protective Equipment Required (please contact cgreen@aiare if you need equipment):

  • Closed toe shoes
  • Long Pants
  • Hard Hats
  • Safety Vests

Site location to be provided after registration. Group limited to 10 participants. Reserve your spot now!

Tour led by:

Gary Klein
Gary Klein, President of Gary Klein & Associates, Inc. has been intimately involved in
energy efficiency and renewable energy since 1974. One sixth of his career was spent in
the Kingdom of Lesotho, the rest in the United States. Since the early 1990s he has led
the effort to incorporate “hot water as a system” into the core principles of building
science. After serving 19 years with the California Energy Commission, he has provided
consulting on sustainability since 2008, with an emphasis on the water-energy-carbonhealth
connection. The benefits of right-sizing premise plumbing and water heating
systems are currently at the top of his list. Klein received a BA from Cornell University
in 1975 with an Independent Major in Technology and Society with an emphasis on
energy conservation and renewable energy.
The International Association of Plumber and Mechanical Officials (IAPMO) recognized
his efforts in 2014 presenting him their Green Professional of the Year award. In 2015 the
Department of Energy awarded him the Jeffrey A. Johnson Award for Excellence in in
the Advancement of Building Energy Codes.

Learning Objective 1:
Participants will learn about and be able to describe the cold and hot water distribution systems from the water’s point of view including pressure loss, distance, heat loss; and from the perspective of the installer and maintenance personnel. We will also discuss the impacts on the health and welfare for the occupants and the workers.

Learning Objective 2:
Participants will be able to dentify the opportunities to make improvements to the distribution systems given current and expected future flow rates.

Learning Objective 3:
Participants will learn how to the multi-family complex plumbing systems function and be able to describe the times-to-tap and volumes-until-hot found in this hot water distribution system and how this affects the welfare of the occupants in terms of time, money, water and energy.

Learning Objective 4:
Participants will learn how to apply knowledge from the tour to future designs, taking into account the health and welfare of the occupants in addition to the water, energy and cost savings.
