EHS New Science Facility
• For this particular project an Air Barrier Wall System is not a feasible solution to a more efficient building envelope.
Industry
• In more extreme climates such as Canada, however, this type of system has proven to significantly reduce energy costs associated with heating the building.
• Annual cost savings of up to $6,000 have been seen by using similar Air Barrier systems to reduce air leakage.
• Could prove useful on other high performance/green projects in the future.

Analysis III: Storm Water Reclamation Analysis III: Storm Water Reclamation SystemSystem
Background:
• In the United States approximately 340 billion gallons of water are withdrawn from the sources available per day.
• SWR Systems can reduce potable water usage on a project by up to 60% just by reusing rain water
• A recent survey indicated that 69% of industry members have not worked on a project with a SWR system.
Goals:
•To study Existing SWR systems and their issues impacting construction to better understand how to utilize such systems without incurring cost negating the benefits gained.

Analysis III: Storm Water Reclamation Analysis III: Storm Water Reclamation SystemSystem
What is a SWR system?
• A system that catches rain water runoff and stores it in a storage tank to be treated and reused in the building or irrigation system to reduce the amount of potable water required from the source

CM Concerns and Issues
EHS NSF Building
1. Extensive coordination with other trades to ensure rough-ins and connections are correct before backfilling.
2. Coordination with foundations systems to ensure pump vault is not in the way and is complete before slab on grade is poured.
3. Warranties from manufacturers are not compromised (for pumps and tanks). Is the pump submersible or does it require a conditioned space?
4. Surface above the tank is protected against heavy machinery (especially if close to the building footprint)
5. Delays will result in large schedule impacts since it is on the critical path.
CBFPMEC Building
1. Tanks are not in the way of construction2. Aesthetics of tanks is not compromised during installation3. Crane is onsite for placement of tanks4. Rough-ins are completed prior to installation of tanks5. Gravity lines have necessary drop to maintain flow6. Long lead times for tanks
PSU SALA Building
1. Tanks are not in the way of construction2. Rough-ins are completed and tested prior to tank installation
and backfill3. Gravity lines have necessary drop to maintain flow4. Significant lead time for tanks

Building(Sub grade)
1. No site space required2. Aesthetically pleasing3. Freeze protected (if below

1. Pumps required to allocate water into the building
2. Intense sequencing and coordination issues for installation
3. Critical to the schedule of the project due to sub-grade components
4. Difficult to detect leaks
CBFPMEC Building
(above grade)
1. Pumps to allocate water eliminated (gravity)
2. Sequencing not critical (can install and just hook into rough-in)
3. Coordination with other trades is less critical due to easy access to tanks
4. Easy to detect leaks
1. Aesthetic concerns2. Exposed to the elements3. More space required4. Site Congestion5. Gravity lines take precedence

EHS New Science FacilityConcern/Issue Action Taken Other Possible Actions
1. The pump warranty was voided due to the pump vault not located in a conditioned space.
1. Relocate the pump vault to a conditioned space inside the building footprint
1. Prior to purchasing look into submersible pumps that would save money vs. moving the entire pump vault.
2. The soil above the tank could not have any heavy machinery or load on it after the tank was installed. The tank is located right in the construction path next to the building footprint
2. Early coordination of scheduling trades with heavy machinery prior to installation and backfill of tank
2. Cover area over tank with supports to transfer heavy loads to soil with proper bearing capacity.

ActionsActions
1. The long lead time for the tanks to be manufactured
1. Tank connections and plumbing rough-in to point of quick connection when the tanks were delivered
1. Earlier involvement of the CM/GC with the design to realize this would be an issue
2. A crane with significant capacity was required to place the tanks on the roof significantly after the crane had left from the earlier phases.
2. Brought in another crane with capacity to lift tanks into place. This was costly and time consuming compared to earlier coordination of lifting capabilities. Primarily caused by unexpected long lead time.
2. Early sequencing coordination with the crane to ensure another crane will not need to be brought back on site. This can only be done by earlier purchasing of the tanks to coordinate delivery with availability of the crane on site.

Actions
1. Utility cost savings analysis did not warrant the implementation of this system for irrigation control
1. One tank and the irrigation system were eliminated and the other was left to still obtain one LEED credit for storm water management. One credit was lost however
1. Use a more passive system that does not require pumps for the irrigation system.
2. Better research on Penn States maintenance and irrigation procedures

• The Air Barrier Wall system does not work well for this project but may be explored for future uses with high performance/green buildings
• The upgraded mechanical system is an excellent way to cut energy usage and save energy costs in the long run
• The SWR systems are an extremely useful tool to reduce the use of potable water and protect out natural resources. They are still extremely new but with proper planning and coordination they can be implemented with minimal conflicts on projects.
