Topic: You Can't Afford Discomfort (Repeat)

Speaker: Dan Int-Hout, ASHRAE Distinguished Lecturer


Presentation Info

While much has been said about saving energy, little is said of the downside if the savings strategy reduces occupant productivity. The average salary in any office is 100  times greater than the full cost of heating and cooling that space. Strategies that add to the first, renovation, or operating cost of a space have to be weighed against the potential for reduced productivity when calculating the time to payback.

 We aren’t doing a very good job, it seems. BOMA continues to report that the #1 reason for tenants not renewing the lease is “occupant dissatisfaction with the thermal environment”. ASHRAE Standard 55 describes the conditions that will satisfy a majority of the occupants. It is often referenced in code, and many LEED projects have been awarded a point for compliance, at the design stage, of course.

In practice however, we find that systems don’t operate at design, or even as designed. We will discuss the issues related to maintaining comfortable all loads, and discuss the benefits of ventilation and economizer operations.
