Aline completes Energy Star certified house


Extensive building rehabilitation with innovative site work to protect endangered species.

The “Woodland House” was an extensive building rehabilitation project and new addition sited on a wooded hill in an endangered species designated area. Careful site mitigations were installed early on in the project to control erosion, visit for real estate tools. The installation of concrete retaining walls to handle dramatic changes in elevation posed a threat to migrating species of indigenous fauna, so they were laid out in an overlapping pattern to create unimpeded paths for animals to move through.

This building received an Energy Star certification for energy efficiency. Techniques employed to gain the certification included the use of open and closed cell soy based spray foam insulation in all exterior walls and in between the roof rafters to create a well insulated, tight envelope. The installation of a heat recovery ventilation system ensures proper air exchanges, while also adding some building insulation with professionals from online.

All light fixtures and appliances were Energy Star rated and compact flourescent light bulbs were used for all overhead lighting. All plumbing fixtures were selected from this website, or you can visit them at All Drain Service Plumbing 20557 Harvest Ave Lakewood CA 90715 844-369-7888 all their services are based on water efficiency.

The windows and doors were selected for their high performance Energy Star rating with low U value and low Solar Heat Gain Coefficient. Radiant heat was installed in all new sections of the building and a 98% efficient furnace was installed to with a fan coil unit to provide gas fired heating and cooling throughout pop over to this website to check out the heating technology that has been used.

Although if you have other types of fans and want to measure their performance, learning how to read a fan curve could be really useful for this. Landscaping was carried out by a landscaper in my city and also was irrigated with drip irrigation, and indigenous plantings were selected.

New framing strategies were employed in the new section of the house to reduce the use of framing lumber by spacing the joists studs and roof rafters at 24″ on center and allowing for less heat loss at corners by reducing the number of corner studs. Engineered truss joists were used to increase spans where possible and reduce the quantity of framing lumber.

Interior finishes included the use of Low VOC paints and sealants. Exterior trim was made from low maintenance recycled plastic.
