The key difference between the deep energy retrofit at Castle Square Apartments and standard energy efficiency renovations is insulation, which at Castle Square will be located on the outside of the building. A new super-insulated shell (R-40) will literally wrap the existing building. The super-insulated shell, combined with a super insulated reflective roof (R-40), high efficiency windows (R-5) and extensive air sealing, will increase the insulation value of the building by a factor of ten. The side benefit of the new shell is the visual transformation of the property.
The result will be a building that requires only a fraction of the energy to heat and cool. Additional energy savings will be made using small high efficiency cooling and heating equipment, lighting, appliances and solar hot water. Residents will be able to stay in their apartments during construction, with minimal disruption.
