I am working on design-replacement of two older heating water boilers with two new condensing boilers- 3,300 MBH each. One of my colleagues mentioned that during summer we can use the heating water out of these boilers and preheat domestic water via a heat exchanger. Does this have any energy...
I have a client who asked me to prepare the MEP construction document for an ice rink. I would like to know what the main design requirements are, especially on mechanical side- such as codes, standards, etc. Does the mechanical engineer usually design the ice rink itself or is a third party...
I hope this is the right forum to post this. I am trying to find projects for a small MEP engineering firm. So far I have found out that the most effective way is to schmooze up to architects since owner prefer dealing with one firm (mainly an architectural firm.) Obviously, finding the...
I am working on a project in Dallas, Texas. The owner wants to combine two existing suites in a shopping plaza and make them one large suite. I need to know what approach to take to combine the electric and gas meters.

I have a specific question regarding control of SZ VAV systems. I know once the space temperature is satisfied, we need to ramp down the fan and modulate (close) the CHW vale to maintain DAT (specially for humidity control purposes,) but how exactly should the sequence of operation be for...
Does anyone know a website or have any tips on writing "introducing our company" emails to architects? How can I word the email to get them to at least give us a meeting?
What is the recommended temperature and RH for Libraries in K-12 schools.
ASHRAE HVAC Application handbook- 2011, chapter 7 says:
" To avoid growth of mold and mildew, a dew point above –1°C (33.8 F) and maximum of 55% rh are recommended.
Does this mean we can not have a temperature of 72 F...
