The Lahaina Welcome Center was largely designed by studying passive solar design. This research covers the basics of passive solar design and how it increases energy efficiency. Buildings consume 40% of the total energy use worldwide, and it could easily increase if no energy efficient matters are taken. Passive solar design is an affordable way to help buildings be more energy efficient and harness the energy of the sun.
Building design is more important to energy efficiency than technology in the buildings, and this is critical to think about in the design phase. Passive solar design is able to increase daylighting, heating, and also passive ventilation and cooling. Green roofs are also a large supplement to passive solar design. Overall, passive solar design reduces heating, cooling, and electrical needs of the building and reduces the building’s carbon footprint.
The building features large overhangs, a green roof, daylighting potential, and optimal positioning for the site. The structure also features permeable pavement for the road and for the parking area to allow better water management of the site. Xeriscaping was used in the landscaping of the design. Material selections of the building were also taken into account. This includes durability, local sourcing, and life-cycle analyses of the materials.
