- Geo-Thermal Systems
On the Outer Banks, building placement and foundation construction play a significant role in designing and building homes with optimal energy usage. By considering factors like topography, soil quality, sunlight exposure, and natural vegetation existing on the lot, we can select natural shade and windbreakers in mind to effectively reduce the overall energy demand of the home.
Step #1: Design for an Energy-Efficient Building
The design phase begins once an ideal site for an energy-efficient building is identified. Every aspect of the floor plan is meticulously crafted to optimize space utilization and minimize energy consumption for heating, cooling, and lighting.
Strategic Door & Window Placement
Strategic placement of windows, doors, and skylights maximizes natural light exposure, reducing reliance on artificial lighting sources. Strategic design elements such as thermal mass and shading devices are integrated to stabilize indoor temperatures and mitigate overheating or undercooling during extreme weather conditions.
Additionally, well-designed overhangs, awnings, and shading devices effectively control solar heat gain, reducing the need for active cooling during warmer months.
Passive Design Principles
The integration of passive design principles further elevates energy efficiency. By orienting the home to capitalize on solar gain in winter while minimizing heat gain in summer, the reliance on mechanical heating and cooling systems is significantly reduced.
Incorporating materials with high thermal mass facilitates the storage and gradual release of heat, enhancing comfort levels year-round.
Step #2: Build with Sustainable Construction Techniques
Constructing an energy-efficient home demands a commitment to sustainable construction techniques that prioritize environmental responsibility, long-term durability, and resource conservation.
Additionally, our approach to Green Home Construction extends to collaborating with energy consultants and other professionals who assist in ensuring that our construction practices align with the principles of sustainability while enhancing the resilience and durability of the building when possible.
Source Sustainably Certified Materials
Before we begin construction we prioritize sourcing materials with low environmental impacts meaning they are either recycled, reclaimed, or found locally.
We always opt for materials that have a long lifespan and require minimal maintenance since the Outer Banks’s environment includes many corrosive elements such as wind and rain. Some great resources we use to find sustainably certified materials include:
Insulation and Air-Sealing
After energy-efficient materials are selected and the frame of the home is complete we install high-performance insulation and implement air-sealing measures to eliminate gaps and voids where energy can escape.
High R-values for insulation and low thermal conductivity for insulation minimize heat transfers through the walls, floors, and roof. We use spray foam, cellulose, or rigid foam boards to install insulation and use caulk, weatherstripping, and seals to prevent air and heat loss.
Blower Door Tests & Thermal Energy Inspections
To ensure the effectiveness of our insulation and air-sealing efforts, we conduct thorough blower door tests and thermal energy inspections. These assessments enable us to pinpoint any areas where energy may be escaping and address them promptly.
While energy-efficient doors and windows typically feature tight seals indicated by U-values, we go the extra mile to verify their performance. The result of these comprehensive inspections is exponential energy savings and enhanced efficiency for your home.
Step #3: Install Energy-Efficient Home Systems that Operate on Renewable Sources
Our approach to installing energy-efficient home systems focuses on integrating renewable energy sources that reduce the overall reliance on non-renewable sources. By carefully assessing the existing conditions of the construction site, energy needs, and local regulations, we determine the most suitable renewable energy options for each home system.
During the installation phase, we may incorporate renewable resources like solar photovoltaic panels, wind turbines, or geothermal heat pumps, tailored to site conditions and energy needs. Our ultimate aim is to maximize the utilization of renewable energy sources, thus fostering sustainability and minimizing environmental impact.
