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"?

Hello, We are working on a residential project where the HVAC system won´t be provided for the apartments, the project scope contemplates the preparation and space for the equipments so every own

Is there any further definition of this part of the requirement? What other than furnishings has been tracked to achieve this credit?

Does anyone have an idea what process water using appliance could be considered "other?" i.e. a pulper, waste collector, both alternatives to disposals?
