The exterior walls of the building appear to be all CMU

with a brick veneer. From previous drawings, there does

not appear to be insulation in the wall cavity. While a

sturdy and long lasting system, it is not the most energy

efficient wall system. We recommend that the interior

renovations include the installation of a furred out

interior wall with 1” rigid insulation against the CMU and

then a 1/58” metal stud wall with impact resistant

gypsum board for the finished interior surface.

All new replacement windows are recommended for the

buildings. There are a few areas where new openings

are a part of the design and many more where the

existing exterior openings will remain the same. In either

case, we recommend an aluminum window wall system

(thermally broken) with 1” insulating glass and

appropriate low-E coatings for the different facing

elevations. New glass doors and walls would be of the We do not believe the existing school walls have the insulation layer that is shown here

same type. Single doors may be hollow metal with

vision lights. At this time, we do not recommend
operable windows, as this climate does not provide

many times of the year where they can be effective and

it would require some type of control system when

outside conditions were not favorable.

Along some of the interior corridors, the ceilings are

lower than the adjacent windows. In these instances, we

recommend a fixed transom at the window heads that

will accept the lower ceiling framing and a spandrel

glass above to cover the exposed plenum space.

Insulated glazing with a low-E coating helps minimize heat transfer and solar gain
