Lights at the entry of a home that help guide visitors and provide security. These pieces can also be used to light breezeways.
ER Lamp
Ellipsoidal reflector lamp is a soft glass lamp that focuses the beam about two inches in front of the bulb. It is designed to improve the efficiency of deep baffle recessed downlights.
A systemized approach to measuring, recording, and evaluating the operating performance of a building system with the intention of improving the performance.
Examples: ASHRAE's Guide for Commercial Building Energy Analysis.
(as relates to ASHRAE/IESNA 90.1 and LEED) Energy Cost Budget refers to the baseline case of the project as defined by a standard such as ASHRAE 90.1. The energy cost budget establishes the energy efficiency target for the building. It is the estimated annual energy cost for the budget building design. The energy cost budget is compared to the design energy cost which may not exceed the budget. The design energy cost and the energy cost budget are calulated as separate runs by an approved simulation program using the rules spelled out in a standard such as 90.1. The comarison is used to establish LEED credit for optimizing energy performance in the Energy and Atmosphere Catagory in the LEED Rating System. (reference: LEED-NC 2.1 reference guide and ASHRAE 90.1 User's Manual)
Etched Glass
Glass treated by an acid bath, producing a satiny, diffused surface or design.
