Subject: [BLDG-SIM] PV, Double-Wall, Energy Programs

 

 

PV

I am looking for information on high-rise buildings that utilize power from PV panels on vertical exterior wall surfaces.  What are the typical applications for power from PV panels in existing buildings?  Where can I find technical literature on how this power is converted, stored and utilized?  What would be an estimate of the usable power per month per unit area of PV panel for the East, South & West vertical surfaces for say 42 degrees North latitude? Are there any studies of maintenance costs and payback?  Are there examples of how to show energy savings from PV panels for code compliance and LEED certification using energy analysis programs?

 

Double Wall

Are there examples of how to show energy savings from double-wall buildings for code compliance and LEED certification using energy analysis programs?  The model I am looking at consists of single glass on the outside and double glass on the inside.  The objective is to trap the radiant heat in the cavity in winter and ventilate the cavity in summer.  Ventilation would be from stack effect due to openings at the top and bottom or forced ventilation.  Does the depth of the cavity space make a difference?  Is there a significant difference in stack effect if the cavity height is one floor or two or more floors?  What are the recommended properties of the two glass walls to trap the heat in the cavity in winter and maximize the transmission of light at all times?

 

Energy Conservation Measures (ECMs)

Are there examples of how to show energy savings for code compliance and LEED certification using energy analysis programs from (1) under floor air distribution, (2) displacement ventilation, and (3) occupancy based lighting & ventilation controls?

 

Energy Programs

Has there been a survey of which energy programs are being used by A-E design firms to show energy savings for code compliance and LEED certification?
