Energy efficiency and green concepts are essential to the construction of a very Smart Loft. From the building envelope, solar systems, lighting fixtures, landscaping and contractors, we strive to make our buildings Smart in every way. Below is a summary of some of the key components and practices incorporated in each Smart Loft we build.
Solar Energy Technologies:Each building has a 3KwH photovoltaic (electric generation) system that averages ~$60/month savings on a TEP standard rate plan electric bill. Each Unit (2 per building) also has a solar hot water system which may account for up to 30% of a homeowner’s electric bill; depending on usage. Enphase micro inverters were installed to maximize energy production.

Integra Block with foam insulation in each cell. Long lasting masonry
durability and super insulation efficiency (R value 24+; R19 is customary in
the construction industry).
Dual Pane Windows: Windows
are dual pane and glazed to achieve an optimum barrier from both the heat and
cold. Low-e ratings (+/-: U-FAC .39; SHGC .23; Visible .45).
Heating, Ventilation, and Air Conditioning: High efficiency 14 SEER package heating and cooling system
installed. Exposed interior duct work in air conditioned space minimizes heat
gain/loss from ducting
leakage. Each room is equipped with a ceiling fan to optimize in room comfort
gained from air movement. Bathrooms include energy efficient ventilation fans (70+CFMs).
Kitchen Appliances: All
kitchen appliances qualify for the Energy Star certification and require lower
average electric to operate. Dishwasher is low water usage.
Laundry Facilities: Each unit
has its own laundry facility. They are best designed for a front loading
stacked washer and dryer, which tend to be more efficient than conventional
top-loading models. Front load washer use less water to
operate than top loaders (20 gallons versus 40 gallons). The dryers, which are
Energy Star rated, can save at least $70 per year on electricity compared to
conventional dryers. In addition, the laundry facilities are located in the
shed on the courtyard outside of the home space so the conditioned space is not
affected by the heat put off by the dryer.
Lighting: All of the light
fixtures, inside and out, use an energy efficient compact fluorescent or
halogen bulb, which
require a quarter of the energy compared to the traditional incandescent bulb.
Leasing agreements and guide books notify the tenant that all bulbs will be
replaced by the landlord to ensure proper replacement of the most efficient
Plumbing Fixtures: All plumbing fixtures are low flow, including the shower heads at less than 1.5
gallons per minute and toilets at less than 1.5 gallons per flush. The toilets
are equipped with a handle that allows the user to use a less than full flush
to pass non-solids to the sewer.
carpeting is made from at least 30% post consumer recycled plastic bottles.
Metal Work and Decking: Various metal components within the homes and the structural beams for the
decks on each unit were sourced from metal recycle yards and are re-used metal.
In addition, Trex Decking was used for the floor boards on all decks and is a
~90% by-product from recycled single use plastic bags.
Concrete Finishes: The
first floor of all homes have polished concrete floors, which improve indoor
air quality. Countertops are also made from concrete with a polished durable
food safe finish.
Landscaping: Approximately 90% of the
original plant material located on the site is preserved. Additional
landscaping is native to the Sonoran Desert and requires minimal water. Run-off
from the buildings is harvested to each plant, staying on-site with minimum
run-off. Necessary seasonal irrigation is on a 2-zone drip system.
Subcontractors: Approximately 90% of all
products, materials, and labor to build the Smart Lofts were sourced from
local Tucson businesses.
