Landis Construction Corp. completed this USGBC LEED-H Platinum Level Renovation of a 100+ year old historic home in Georgetown. The entire home was reconfigured and updated with new systems and a two-story addition with a full basement at the rear.
Through LEED’s rigorous planning, testing and documentation process, special attention was paid from design through completion of construction to ensure the home was: 1. well constructed; 2. greatly exceeds current energy efficiency standards; 3. manages water resources; 4. promotes healthy indoor air quality; and 5. produces a limited waste stream during demolition, construction and the life of the home.
Four of the biggest green-related challenges come from integrating 21st century building science into a historically protected 19th century home; educating themselves, trade partners and vendors about the fundamentals of sustainable design and construction; changing the way they go about designing, planning and producing a renovation that is required by the LEED process; and making sure that all the proper documentation that LEED requires was done, which is not part of a standard remodeling project.
To highlight a few things on the project, Fusiotherm Polypropylene piping was used for the water supply throughout rather than copper or PVC and Demilec open-cell, high soy-content spray foam was used for nonbasement walls and roof rafters while Demilec closed-cell, high soy-content spray foam was used for the basement walls. LED lighting was installed throughout the home in the form of recessed cans and under-cabinet lighting, as well as some CFL and fluorescent tubes used in closets and stairwells.
The renovated home honors the elegant detailing and finishes of its historic period. However, below the surface, the home boasts many cutting-edge building technologies. The house is more than twice as energy-efficient as a home constructed to today’s energy code.
