I'm working in a small project with natural ventilation overall. Considering these 3 facts: 1. LEED states to comply with sections 4-7 of ASHRAE 62.1-2007. 2.

Our company is in the process of determining whether a commercial interiors project is ideal for the EAc3 submetering option for Case 1.

We are a bit confused as to the meaning of space fan and pump sizing? Could anyone please offer some clarification? Thanks!

Dear Sir/ Madam, I have a project that is a hotel with 200 guest rooms that are non-densely occupied. Each guest room floor (20 rooms per floor) is supplied with 3 AHUs.

Our project is a large office building with commercial kitchen (in house breakfast/lunch, etc).

Our System is VRV , and the hvac Ashrae forms - part 1 and 2 - does not comply with vrv system - how we could comply with them and many of them does not comply with vrv system ???????????

We have a large residential project that has natural ventilation being used. Are CO2 sensors required in every room/bedroom of the apartments?

I am working on a project that was registered under LEED NC 2.2. Will the USGBC allow us to apply requirements from 90.1 - 2010 to the project instead of 90.1 - 2004?

Under ASHRAE 90.1-2007 task lighting must have automatic shutoffs; the owner prefers not to install occupancy sensors/shutoffs at individual workstations.

I am trying to calculate the requirements and was wondering about some technical details. This is for a library on a college university. 1. Does the window sill have to be between 30-90"?
