Title 24 is an estimation of how much energy a proposed building will consume. This estimate is then compared with a comparable ‘code minimum’ building to show that the proposed design is more energy efficient. The results are printed out in the form of a report that can be submitted to building department for permit.
CALGreen also called as the Green Building Code is part of the California building code. It is Mandatory for every building in the state to meet this code. CALGreen covers topics like construction waste management, Flow rates of plumbing fixtures and sustainable building practices just to name a few.
The amount of heating and cooling needed for any given space depends on large number of variables like, Size of space, orientation relative to Sun, climate zone etc. undersized systems simply don’t have enough capacity to provide the thermal comfort. Oversized systems on the other hand would be inefficient and wasteful. For this reason, it is not prudent to follow rules of thumb for sizing HVAC system.
The HERS or Home Energy Rating System was developed by RESNET and is the nationally recognized system for inspecting a home’s energy performance.These inspections are on site verification of the energy efficiency features. – HERS Testing and Inspections
