Services
Net Zero Design
Our net-zero energy homes produce as much energy as they consume through solar panels, super-insulation, and efficient mechanical systems. We utilize HERS Index modeling to achieve energy balance while maintaining aesthetic integration with Cape Cod's landscapes. This approach reduces utility costs and environmental impact for homeowners seeking sustainable living solutions.
Passive House Design
We apply Passive House principles to create buildings that use 90% less energy for heating through thermal envelope optimization and solar gain management. Our designs feature triple-glazed windows, airtight construction, and balanced ventilation systems tailored to Cape Cod's climate conditions and coastal environments.
Historic Renovations
We restore historic structures while incorporating modern energy-efficient systems, maintaining original architectural character through careful material selection and traditional building techniques. Our expertise includes adapting 18th-century homes for contemporary living standards without compromising historical integrity.
LEED Certification
We guide projects through LEED Platinum certification by implementing sustainable site practices, water conservation systems, and construction waste diversion strategies. Our team ensures compliance with rigorous environmental benchmarks while optimizing building performance metrics.
Energy Modeling
Using HERS Index standards, we create energy models during design phases to predict building performance and optimize mechanical system sizing. This process helps achieve energy efficiency goals through envelope improvements and renewable energy integration strategies.
