Building Envelope Systems
The building envelope, which primarily consists of roofs, walls, floors, fenestrations, and doors, is the ultimate demarcation between the external elements and the controlled indoor environment. These envelope components regulate the transfer of air, water, heat, light, and noise between internal and external climates. Building owners and facility managers must address the challenges created by this constant flux of matter and energy.
To answer these particular needs, KHH has for more than a decade provided Building Envelope Systems services. Our firm can furnish you with information about our specific experience relevant to your project. We specialize in:
- Contemporary Masonry Facades
- Historic Masonry Facades
- Building Science Services.
Scope of Services
Contemporary Masonry Façade Rehabilitation
This includes condition assessment followed by development of practical rehabilitation schemes, such as addressing façade cracking, bowing, joint deterioration, water intrusion, lintel deterioration, joint deterioration, and staining. Detail development and construction-phase inspection can also be incorporated.
Historic Masonry Façade Review and Rehabilitation
Our expertise includes knowledge of historic building techniques. Original design durability can be undermined by well-intended, yet inappropriate modern products. We can assess existing conditions, including reviewing mortar to determine type and composition, identify locations of distress, damage and deterioration, as well as develop rehabilitation and maintenance plans.
Building Science Services
Emphasis on energy efficiency and carbon footprints has resulted in a revisiting of traditional building details. A carefully-designed and well-built envelope system, coordinated with the mechanical systems, can greatly reduce a building’s energy usage. Klepper, Hahn & Hyatt can assist with the following:
- Development of roof and wall details to maximize envelope performance
- Specific detailing to minimize energy loss caused by thermal bridging through roof angles, façade support elements, cold-formed steel studs, canopies and balconies, among other elements
- Design and detailing of foundation insulation systems, as well as underslab insulation
- Infrared imaging of existing buildings to identify addressable areas of energy loss
- Building envelope commissioning services, using infrared imaging, as part of project closeout to ensure as-designed envelope performance. This can be useful when striving for LEED Certification.
