We are working on a business tower with 2B+G+ 27+Roof floors. The tower has raised floor with UFAD/TDV systems from ground floor to 27th floors except toilets areas in each floor.

I have two questiones: 1.

I have a multi-story building that has one AHU per floor taking OSA from a common vertical shaft.

I am having a problem with LeedOnLine and USGBC hasn't been any help.

Hello, we have a building with irregular shape of facade. The facade consists of horizontal lamellas with vertical gazing - like steps, 3 per each floor.

Has anyone any feedback in modelling either of these two chillers in a 90.1 Energy model.

We are working on CS project, a shopping mall, 57% is major renovation while the other 43% is expansion.

As the mandatory provision in ASHRAE 90.1 section 9.4, building facade lighting shall not exceed 0.2W/ft2 for each illuminated surface.

Do tenant spaces need to be included in the areas controlled by the automatic shutoff as mentiaoned in section 9.4.1.1 (ASHRAE 90.1)?

We are pursuing Option 1 (Whole Building Simulation).
