What is natural ventilation? Intelligent control of the forces of Mother Nature

We open and close the windows based on:• Indoor air temperature• Indoor CO2 levels• Relative humidity• Outdoor air temperature• Wind speed and direction• Rain • Other parameters.

Title 24

Overview

• Manually openings (wall/roof)to the outside shall haveinterlocks

• If, the space is conditioned(mechanical heated/cooled).

• If, the space has athermostatic control (e.gtemperature sensor).

• If, openings are open formore than 5 minutes.

Requirement

Heating mode:

• Disable or reset thetemperature setpoint to 55⁰Ffor mechanical heating.

Mechanical cooling:

• Disable or reset thetemperature setpoint to 90⁰Ffor mechanical cooling.

Title 24

Overview

• Manually operable openingsto the outdoor are windows,skylights and doors that donot have automatic closingdevices.

• Motorized window are stillconsidered manually operableif occupants can open theopenings as desired and theywill stay open until manuallyclosed= you have to comply.

Def. (manually vs. motorized)

• Fully automated naturalventilation system complies.

• If, the system takes thecontrol back after a period oftime.

University of Baltimore School of Law

“The facade and atrium design led to passive and active strategies that typically aren't applied in this climate. The building's passive design strategies achieve very high performance and flexibility without the use of PV or solar thermal systems.”

The windows will be automatically closed when the air condition is on and made available for the users to open and close at will by the manual override switches, when the air condition is off. This saves energy.

Natural ventilation can be utilized 40% of the time.

A US university have conducted thermal comfort surveys on different buildings –Baltimore scored the highest.

1. Operable windows2. Weather station measuring temperature,

humidity, wind speed and direction3. Weather station alerts occupants to

open/close the windows4. Mechanical system shuts down when

windows are open

All employees have access to operable windows.

Heat pumps shut down when the windows remain open, ensuring energy is not wasted.

All employees have access to operable windows.

One of the largest naturally ventilated buildings in the country. These high-performance features create a high-quality work environment.

University of SF Center for Science and Innovation

Climate-controlled windows, which open and close depending on the temperature and have features to prevent reflectivity and use ambient heat to help control temperature. In line with the campus’ wind patterns, the building is designed to accommodate natural ventilation.

Piping systems embedded in the concrete runwater hot and cold, which helps controllingthe building's temperature.

42% in energy savings from Title 24 baseline

Night time purging via the windows.

07-06-2017

Mesa College Campus, San Diego

Teacher can control the classroom temperature

through a single switch on the wall that offers a

choice between natural and mechanical

cooling. When the temperature falls within the

comfort zone (does during most of the year), the

natural ventilation system disengages the

mechanical air conditioning and

automatically opens the windows.

In the design discovery process, teachers said

they loved to open the windows and doors. This

building encourages that behavior, so it is

expected that the teachers will choose natural

ventilation most of the time.

43% reduction in the building’s energy consumption compared to state requirements

The natural ventilation occurs via high-level

automated façade windows in the classroom. In

the back of each classroom, there are high-level

automated vents, which can lead the air into the

common areas (hallway) where the air is

ventilated out through the high-level automated

windows in the clerestory.
