The Differences in a Lawler-built ENERGYSTAR® Home
Integrated Design Team
Collaborating with our sub-contractors and architect, Lawler Construction works to provide the best solutions to make your home more efficient. We also follow the nationally recognized Home Energy Rating System (HERS) Index to ensure your home will meet all the requirements needed to be an ENERGYSTAR® home.
Using airtight cans for recessed lights and airtight barriers at all exterior penetrations reduces air infiltration into your home. Interior and exterior air barriers throughout your home, along with proper sealing at penetrations, helps to significantly reduce heat loss.
To deliver suitable ventilation, code requirements and calculations are based on the size of a home and the total occupants living there. The more airtight a home is, the need for ventilation increases. Proper mechanical ventilation, as followed by ENERGYSTAR® guidelines, produces cleaner air in your home and also reduces strain on your HVAC unit.
Window Layout and Design
The U-value and Solar Heat Gain Coefficient (SHGC) of a window can make a big difference on how much heat is allowed into your home. Designing each room with the right windows in the right locations will help make your home more comfortable in every season and allow your HVAC unit to operate more efficiently.
The correct type of insulation is a key ingredient to keep your home energy efficient. Lawler Construction may use a combination of spray foam and high thermal resistance (R-value) insulation which helps deliver even temperatures and a comfortable environment within your home. Additionally, the concrete slab of your home will have a 2' perimeter of rigid insulation under the slab. This allows the concrete floor to stay closer to room temperature by blocking the thermal transfer from under the home.
A home that’s correctly sealed, ventilated and insulated eliminates the need for larger HVAC units, which saves you money both short and long term. Ductwork in a Lawler Construction built home is installed as efficiently and airtight as possible, resulting in less strain on your HVAC system. A duct blaster test is then performed to ensure the system is working as efficiently as possible.
