Continuous board insulation is defined by ASHRAE 90.1 (the U.S. energy standard for all commercial and some residential buildings) as “Insulation that is continuous across all structural members without thermal bridges other than fasteners and service openings. It is installed on the interior, exterior, or is integral to any opaque surface of the building envelope.”
World has seen an exponential growth in energy consumption in the last few decades. in spite of this growth large part of our energy still
Energy impacts associated with the hot water distribution systemvary widely based on the type of system, quality of insulation and installation, building andplumbing design, and hot water use patterns. For this reason, it is important to choose the right water heater and have a good distribution system design.
The intent of the solar-ready requirements is to provide a penetration-free and shade-free portion of the roof, called the solar zone. This solar zone helps ensure that future installation of a solar energy system is not precluded by the original design and layout of the building and associated equipment. There is no infrastructure related requirements, such as installation of conduit or piping, inclusion of collateral structural loads, or preinstalled mounting hardware.
The requirements for solar-ready buildings are mandatory measures for newly constructed single-family and low-rise multifamily residential buildings and do not apply to either additions or alterations.
The radiant barrier is a reflective material that reduces radiant heat transfer caused by solar
heat gain in the roof. Radiant barriers are installed below the roof deck in the attic and
reduce radiant heat to air distribution ducts and insulation located below the radiant barrier.
For residential buildings and spaces, all of the lighting requirements are mandatory
measures. There are no tradeoffs between lighting and other building features and lighting is
not part of any component package under the prescriptive method.
The residential lighting Energy Standards apply only to permanently installed luminaires,
including luminaires with easily interchangeable lamps, but do not apply to portable
luminaires such as table lamps or freestanding floor lamps
Insulation is one of the least expensive measures to improve building energy efficiency.
Insulation requires no maintenance, helps improve indoor comfort, and provides excellent
sound control. Adding extra insulation at a later time is much more expensive than
maximizing insulation levels at the beginning of construction.

California Green Building Code, CALGreen – Energy efficiency design is an integral part of any building built in the state of California. All newly constructed building as well as addition and alteration projects are required to meet the minimum energy efficiency thresholds.
Covering and protection of ducts and mechanical equipment during construction in a CALGreen mandatory measure. It is applicable to all Residential and Non-Residential projects. This measure is triggered if there is a probability of any part of the HVAC system being exposed to dust and fumes from the construction process.

CALGreen promotes sustainable bio-based materials that are rapidly renewable and are responsible harvested. This is an elective measure that can be selected to meet CALGreen Tier 1 and Tier 2 requirements.
This is an elective CALGreen measure and can be used by remodeling and rebuild projects as well as new construction projects building on previously developed lots. The CALGreen code language is as follows.
