Inclusive and Specialized schools - Design requirements

• Class Composition: Class size averages between 8-12 students depending on age level and classroom dynamics.

Lower Elementary Age (2-4)

Middle School Age (6-12)

High School Age (13-16 )

Fig 6: Figure showing grouping of students according to age group

• Staffing: Each class has one teacher and 2-3 full or part time assistants. If a classroom is experiencing significant disruptions, a temporary support assistant (TSA) may be assigned to support the classroom or an individual student for a brief periods of time so that the teacher is able to establish instructional control.

The teacher-pupil ratio in specialised education is 1:5

• Student Services: Classroom time and Designated Instructional Services (DIS) for each student are based on individually assessed needs and IEP team decisions.

Services may include but are not limited to

Speech & Language

APE, OT, PT Assistive technology

Self-regulation

Individualized, specific skill training

Social skills instruction

Positive behavioural support

• School Psychologist: A school psychologist is assigned to support the special day classes. This individual must be able to conduct assessments and file reviews for students with autism spectrum disorders, may be able to handle intakes and placement changes, in addition to other administrative and typical duties assigned to this role. The school psychologist may be required help develop a behavior plan and act as a trainer in assault prevention and management.

The school nurse provides training and support for all • S pecialized health care needs • M edication management • T he school nurse monitors dietary and nutritional needs • R equired health care documentation, including medication monitoring.

• Curriculum: The classroom provides common core curriculum, with modifications as appropriate. Instruction may be offered in the following domains

• Daily living skills • Functional academics • Gross and fine motor skills • Social communication • Community based instruction • Vocational preparation and recreation/leisure. 1

Inclusive and Specialized schools - Design considerations • Building Security: This consideration not only refers to outside factors, but to student safety as well. Special education students can be at an increased risk of bullying. So transparency into all shared spaces supports passive supervision throughout the school.

There is also a tendency among the students on the spectrum to wandering. Therefore there should be visibilty to the outside spaces from the classrooms.

• Parent spaces: Parents of children in special education are inherently committed to being deeply involved in their children’s school. Designing for special education must also acknowledge their needs and provide community spaces to meet, store their belongings and socialize.

• Equipments and Furniture: Specialized equipment and furniture such as foam wedges, therapy balls, walkers and swings help staff and students to customize use to particular needs. These options are important to accomodate a wide range of learning activities. So provision of lot of storage is a design aspect to be considered • Layout: In considering layout and adjacencies, high-stimulus areas and low-stimulus areas. High stimulus areas include art rooms, media rooms and cafeterias. Low-stimulus areas provide spaces to focus, such as classrooms, one on one conversation areas and study spaces.

Transistional spaces must be created to help the students prepare and adjust Low sensory activities

‘Kalpatha’ orginating from Sanskrit means eligible. Every child is eligible for education.

Every child is eligible for a memorable childhood.

The main intention of the school is to ready the children with ASD to be able to navigate in a neurotypical society.

The school mainly consists of classroom that are designed to be comfortable to children on the Spectrum. Along with the classrooms, necessary spaces such as therapy spaces, vocational rooms and life skills room is provided.

STEEL REINFORCEMENT

FILLER MATERIAL

Fig 11: Section showing Filler slab

Three low-cost roof insulation solutions namely Burnt Clay Pots (BCPs), Wood shavings, and Hollow Clay Tiles (HCTs) are tested in this study and following important findings are revealed: (1) Use of 10 inch diameter inverted BCPs reduced the inside temperature (or cooling load) of the room by 52% as compared to the uninsulated reinforced concrete roof.

It helps in better thermal insulation due to the air pockets present in it. The concrete required in this technology is about 20% and steel is 30% less required than conventional slab construction. As a result, reduces self-weight and also costs by 20- 35%.

Water Performance: Water usage is an integral aspect in designing sustainable designs. Due to the water crisis in India, it is necessary to accumulate, effectiviely utilize and safely dispose water. According to the NITI (National Institution for Transforming India) Aayog, our country recieves around 4000 billion cubic meters of precipitation including snowfall. The current status of the water levels are as follows 1
