Day2_TrackB_Passive Solar Building Design & Energy Analysis through BIM (IP52)

[Andrew Fisher]

W Brent Swain speaks about, among other things, structural insualted panels (SIPs)and their application in the US and throughout the world. Brent announced that he will be moving to Mississippi to work with passive solar in the wake of Katrina.

Some of the things we will learn in this discussion are:
- a better understanding of energy code requirements for residential buildings, as well as basic concepts and strategies for better energy performance through passive and actives strategies.
- an understand how BIM is used to package building data and interface with other software tools

Passive Solar 'best practices' were all gathered into one book in 1984 -- 'The passive Solar Design Handbook'.
One of the things we might do today is to examine how these might be employed with current materials and construction methodologies.

Everybody knows about global warming and what could happen in the future

Potential risks of 2 deegres Celsius rise above pre-industrial levels are:
-12-40 foot sea level rise
-Serious economic and life consequences

Thats is why we have to start ussing passive design strategies.
Look at the passive solar design handbook (Van Nostrand Reinhold, 1984) it is the best book to look at this systems
Systems: DG, TW,WW,SS

Passive cooling strategies include: Natural ventilation, ventilation W/high mass cooling, solar shading, daylighting, evaporative cooling

Start implementing them in your design that the future depends on the way how we design our buildings.

Some software recommended in this session:
GreenBuilding Studio (https://www.greenbuildingstudio.com/About.aspx) is an AutoDesk product that can plug-in to ArchiCAD or Revit.
REScheck is ann application that can verify energy compliance for your project and ENERGY-10 is an application that can give you an accurate prediction of energy performance.
Both of these programs work by asking you some quantitative questionsa bout your project or existing building and then provide feedback. (It only takes a few minutes to answer the questions according to our speaker)
The department of energy has a program called eQUEST, an update of an old DOS program that can do full performance simulations. It can be found a the DOE's website (www.doe2.com)

About passive solar heating

I hope you know that you are not going to double the savings if you put two passive solar systems together!!!
Intuitively this wont happen since there will still be likages in the space, heat loss through the windows, etc.

Do you know???

The commercial and residential sectors, those most impacted by building envelope design, are lagging behind the 7% average of renewable consumption –at 1.5% and 4.6% respectively.

By 2030, those sectors are expected to consume 23.8 quadBTU, up 26%. An equal 12.6quad BTu offset would be a step towards sustainability, but a worthy goal.

Therefore design with your eyes open and if you have any questions about this topic write to:

I was somewhat surprised to learn that:
Renewable energy is a small part of the whole picture of energy delivery, and solar represents a similarly small percentage of all renewable energy sources.
