Heavyweight Lightweight Comparison

Post by Richsa »

Hi there,

I am attempting to model "The House that Kevin Built" (http://www.bbm-architects.co.uk/index.p ... Itemid=107), essentially it consists of a lightweight top floor and thermally massive heavyweight bottom floor.

After speaking to the architect of the project it appeared that the top floor has suffered from overheating. I am therefore attempting to identify this in IES, i.e. build a 2 story house with the top floor overheating and the bottom floor having a comfortable internal temperature due to the presence of thermal mass.

Is this possible to model for the same house? any advice whatsoever would be grand as I feel its only a matter of time until I start pulling my hair out?

Thank you in advanced,

Rich

Hi Rich,

I might be over-simplifying but it sounds like all you need to do here is get the geometry right (ModelIt or import from Revit or SketchUp if that's easier).

Then in Thermal you can use Constructions Database to create the Constructions for top floor and bottom floor as required. Assign these to the rooms on the top/bottom floors and you should be ready to simulate. You might want to use predefined thermal templates as a starting point by importing via the plug-ins.

would be interested to see what software was used to produce the EPC too...

yeah most of my searches on Google showed EPCs generated by SBEM. Would love to see some stats on buildings that used DSM Vs SBEM though, esp if they are built and have some data on how they perform in the real world compared to the theory.
