The Kalaeloa NZE Community is a 15 acre compact, mixed use, community integrating net zero sustainability concepts with affordable and workforce housing choices and small commercial spaces. Comprehensive and thoughtful environmental building and site design, along with energy from the sun will eliminate the need for fossil fuel energy on site. Kalaeloa NZ residents will benefit from the elimination of future energy costs and enjoy a light imprint, pedestrian oriented neighborhood among the green streets, plazas, community park and green spaces.
The neighborhood will mix various housing types [stacked flats, rowhouse, townhouse, loft and carriage house] in 2 and 3 story structures with a mix of 1, 2 and 3 bedroom dwelling units. A Community “hub” is located on the “makai” end of the neighborhood incorporating retail spaces, community post office, plaza, bus stop, and community garden. 47% of the site is open space and landscaped in a variety of patterns including, native materials, water quality elements and edible landscapes.
Kalaeloa Net Zero emphasizes energy use reduction and energy production through the following 4 Prime Principles:
BUILDING ENERGY REDUCTION
Reduce the amount of actual and embodied energy through the design and construction of the housing types incorporating: natural ventilation and daylighting; shading of exterior windows and walls; higher degree of building insulation; roof shading; higher ceilings; light exterior colors; no air conditioning or heating systems; energy star appliances; rain screen exterior systems; modular and panelized construction techniques. Building plans are modeled and interactively designed to optimize efficiency.
BUILDING ENERGY PRODUCTION
Photo Voltaic roof top mounted electrical systems tied back to the electrical grid; Solar Thermal roof top mounted hot water assist systems; Incorporate electric car recharge stations at each car port. Systems are sized to provide all of the required electrical power used on site.
Utilize low flow fixtures and energy star appliances throughout the dwellings; Capture and reuse rain water and sink flow and potential brackish water recharge for toilet flushing; Extended use of permeable paving and hardscapes for streets, drives, parking and plaza’s; Natural water quality filtration through surface landscapes, bio-retention swales and rain gardens; Natural channeling of storm water via sculpted water courses; Natural storage through a flowing park. Utilize low water, native Hawaiian plant materials as well as edible landscape material.
Recycling centers on every 1/2 block for paper, glass, plastic, metal, and food waste. Incorporate neighborhood scale Anaerobic Digester on site to receive and process all waste water, food waste, and sewage to produce an end use product such as fertilizer to use on site.
