When the Texas Legislature Passed House Bill 3693 it set reality guidelines regarding energy productivity programs and incentives as well as other energy performance measures. Part of the Bill’s guidelines requires schools to establish a objective to reduce the school district’s annual consumption of Texas Electricity. In response, Texas State University set a goal about 2.5% electricity consumption for FY11.
However, during the first quarter of FY11, the campus experienced a 6.5% increase in Texas Electric consumption as compared to the symmetrical periodic last year. This is attributed to the increase of more than 1600 students enrolled thus well as warmer months during the start of the fiscal year. As a result, the campus was utilizing labs and classrooms for longer periods resulting in an enlargement in Electricity consumption.
This increase in demand and Texas State University’s commitment to adhere to their electricity consumption goals prompted the campus to initiate energy savings programs. With their power to choose vigor options, the campus has established a comprehensive energy savings program that other campuses furthermore conventional could learn from.
Current Energy Discount Plans
The following describes some of the current energy reduction plans being implemented by Texas State University in order to hit their Texas electricity consumption goals for FY11.
* Energy Audits – a minimum of 2 detailed energy audits per month is set by the university starting with areas that are the largest consumers of electricity such as building with air handlers that are in operation for 24 hours a day, seven days a week.
* Lighting Retrofits – luminous bulbs will be eliminated and replaced with more energy-efficient compact fluorescent lamps in all facilities. Old style fluorescent lamps will further be replaced with more efficient T-8 fluorescent bulbs. At the same time, old magnetic ballasts will be replaced with further efficient electronic ballasts for less Texas electricity consumption.
* VFDs on Chilled Water Systems – Variable Normal Drives or VFDs are installed on all chilled water pump facilities to have more careful and more energy efficient control of the shoe motors used in the chilled water systems. This precise control system will let only the required cooling needed in the building spaces to maintain human comfort levels within the facilities.
* Extended Heating Load Downtime – To increase energy savings during winter breaks, Housing Services set building programmed controls to swindle extended heating bear downtimes.
* Building Re-commissioning – The campus completed in-house re-commissioning of their Math and Science buildings and disposition realize payback in less than a year.
* Replacement of Faulty Air Dampers – Marred air dampers in a facility leads to cooling losses which will eventually be translated condition higher electricity consumption. To prevent this, faulty air dampers such as those encountered at the Law School were replaced with new and more efficient units.
* Dedicated Cooling Pump for Biology Building – A dedicated cooling pump is planned for use in the Biology building’s growth chambers. A dedicated pump in these chambers will allow the larger building cooling pumps to cycle off without pretentious the conditions in these growth chambers. In this way, greater energy savings can be realized.
Future Vigor Attrition Plans
Aside from the energy savings initiatives formerly implement alongside the Texas Snit University, other energy savings projects are planned to obtain even greater reduction in the consumption of Texas Electricity. This involves the use of LED lighting retrofits, smaller ballasts, upgrades on HVAC controls, rolling off-cycles for chillers, and air-handler upgrades. Engineering analysis is currently ongoing to check on the feasibility of these additional projects to determine those with the biggest impact, least funding requirements and favorable payback periods.
