Oversizing the HVAC system is detrimental to energy use, comfort, indoor air quality, building and equipment durability. All of these impacts derive from the fact that the system will be “short cycling” in both heating and cooling modes. To reach peak operational efficiency and effectiveness, a heating and cooling system should run for as long as possible to address the loads. Short cycling limits the total amount of air circulating through each room, and can lead to rooms that do not receive adequate duration of airflow. In the cooling season in humid climates, cold clammy conditions can occur due to reduced dehumidification caused by the short cycling of the equipment. The system must run long enough for the coil to reach the temperature for condensation to occur and an oversized system that short cycles may not run long enough to sufficiently condense moisture from the air. Excess humidity in the conditioned air delivered to a space may lead to mold growth within the house.
presentation is prepared for the subject of ,,Regions and Cultures" by the Georgian students team. presentation consists of different topics about Georgia, such as History, Geography, Georgian traditions, religion , tourism statistic, wine making tradition, historical and cultural heritage and so on...

Great place to visit.
If you're looking for a beautiful architecture and a place to spend sometime time.
I receive several PowerPoint presentations through e-mail, so I thought I'd share them. I just post them. I didn't creat them :)

Energy Show 2022 - Opportunities and Challenges to Upgrades in the Commercial...SustainableEnergyAut
The Government's plan to address Climate change includes ambitious targets. This session will focus particularly on the targets relating to the retrofit non-domestic buildings. It will discuss some of the challenges and opportunities to meet these goals.
Discussions will be around a holistic approach to retrofitting of buildings, bringing the reduction in energy requirements to the fore.
Speakers will cover some of the main pressing questions faced by those designing and managing non-domestic buildings in today’s current climate. All speakers have extensive experience in their particular topic and have worked for many years within the construction industry.
The sub-topics included within this session are outlined below:
Challenges to Commercial Retrofit Ventilation Energy efficiency & Covid
Façade Upgrades and Carbon Reduction in Commercial Retrofit
Benefits of Building Digitalisation & Optimisation.
This session will be both practical and relevant for anyone designing, constructing and supplying these projects.

The purpose of this presentation is to discuss the underlying science behind data center airflow management and how applying best practices can make the greatest impact on the computer room, both in terms of energy savings and capacity.

Architects, building owners and facility managers who
work with large industrial buildings are under growing
pressure to seek solutions which not only save energy and
money, but also help achieve their green business goals.
In response to this Airius destratification systems are
being increasingly turned to as the most cost effective
method to reduce HVAC costs and carbon emissions by
20% - 50% (or more when used in facilities with process
heat), whilst also ensuring comfortable conditions are
maintained for staff in order to sustain productivity.
Maintaining comfortable environments in
offices is one of, if not the most expensive
running cost for such a building. Even then
ideal conditions can be extremely difficult to
achieve, which can have a severely negative
impact on sales and productivity.
The Airius destratification system optimises
existing HVAC systems by circulating
temperatures evenly throughout, removing
hot and cold spots and balancing
temperatures to within 1-2°C, saving
30%-50% on your HVAC costs.
Australasian Lab managers Conference: Gas Generation Dr Nicole Pendini 2019Nicole Renee Pendini
This presentation focus on on-site Gas Generation for the laboratory space supplying a range of analytical and specialty applications within the lab environment. I will focus on keeping green by preventing weekly cylinder and bulk supply deliveries, that waste energy offsite to generate the gas and petrol to delivery to the laboratory. The overall cost savings vs other methods (ROI < 1.5 years including service) and of course how Laboratory managers can significantly reduce their OHS/E risk with onsite Nitrogen, Hydrogen and Zero Air gas generators.
Plumbing Design Package includes over (18) Programs and Forms that include: "accurate" water pipe system sizing, waste and vent system sizing, roof drain system sizing, natural gas system sizing, water heater sizing, and several additional Plumbing Design tools.

20. The Dry Run Plan A Wed. November 28th 8am – 12pm Shut off both air handlers and most building exhaust and monitor the temperature rise across the building noting potential trouble and reinstating air flow if a danger level is reached. Plan B Wed. November 28th 8am – 12pm Shutdown air handler 1 and lower the exhaust flow as shown in the phasing diagram. monitor the temperature rise across the building noting potential trouble and reinstating air flow if a danger level is reached. 12pm-4pm Shutdown air handler 3 and lower the exhaust flow as shown in the phasing diagram. monitor the temperature rise across the building noting potential trouble and reinstating air flow if a danger level is reached.
