Natural Light & Architecture

FYI: Consultation on IES RP-46 Recommended Practice: Supporting the Physiological and Behavioral Effects of Lighting in Interior Daytime Environments closes April 10: 

Designing Lighting for People and Buildings

Advantages of natural light in educational occupancies:

  1. Improved academic performance: Studies have shown that students exposed to natural light perform better academically compared to those in classrooms with artificial lighting.
  2. Energy efficiency: Natural light can help to reduce energy consumption and costs associated with artificial lighting.
  3. Positive impact on health and well-being: Exposure to natural light has been linked to improved mood, reduced stress levels, and better sleep quality.
  4. Reduced absenteeism: Natural light has been shown to reduce absenteeism in schools, which can have a positive impact on student learning outcomes.

Disadvantages of natural light in educational occupancies:

  1. Glare and heat gain: Natural light can create glare and heat gain, which can be uncomfortable and distracting for students and teachers.
  2. Inconsistent lighting levels: Natural light levels can vary throughout the day and seasonally, which can make it difficult to maintain consistent lighting levels in a classroom.
  3. Limited control: Unlike artificial lighting, natural light cannot be easily controlled or adjusted to meet the needs of a specific classroom.
  4. Exposure to harmful UV rays: Prolonged exposure to natural light can also lead to harmful UV exposure, which can increase the risk of skin cancer and other health problems.

Overall, natural light has many advantages in educational occupancies, but it is important to carefully consider the potential disadvantages and to design spaces that optimize the benefits of natural light while minimizing the drawbacks.

Architecture and Aesthetic Education

“The most enduring architectural works  are those

that speak to the timeless principles of beauty and order.”

— Roger Scruton

 


Form v. Function | Function v. Form

“We shape our buildings;
thereafter they shape us.”

— Winston Churchill

“The Architect’s Dream” 1840 Thomas Cole

Occupancy classification is “first principal concept”; the essential factor in architectural design because it helps determine the appropriate use of a building and the associated requirements for fire protection and life safety. Occupancy classification refers to the categorization of buildings or portions of buildings based on their intended use and the activities that will occur within them.  The International Building Code provides a set of standards for occupancy classifications that are used by architects and building officials to ensure that buildings are designed and constructed to meet the necessary safety requirements. These standards help ensure that the building’s design and construction comply with fire and life safety codes and regulations.

A building that is classified as a business occupancy — as many classrooms and offices are in education communities — will have different requirements for fire protection and life safety compared to a building that is classified as a residential occupancy. Business occupancies may require fire suppression systems, while residential occupancies may require smoke alarms and carbon monoxide detectors.  Additionally, occupancy classification affects the number of occupants allowed within a building, the type and size of exits required, the need for fire-resistant construction materials, and the placement and quantity of fire extinguishers and other fire protection equipment.*

* The European Union (EU) does not have an equivalent to the International Code Council (ICC) occupancy classification system. Instead, the EU has its own set of regulations and standards for building safety and design, which vary by country.

The main regulatory framework for building safety in the EU is the Construction Products Regulation (CPR), which sets out requirements for construction products and materials that are placed on the market within the EU. The CPR is supported by national building codes and standards, which are developed and enforced by each member state.

In addition to the CPR, the EU has several directives and regulations related to building safety, such as the Energy Performance of Buildings Directive (EPBD) and the Fire Safety of Buildings Directive (FSBD). These directives and regulations set out requirements for energy efficiency, fire safety, and other aspects of building design and construction.

Overall, while the EU does not have an occupancy classification system equivalent to the ICC, it has its own set of regulations and standards that aim to ensure building safety and design across its member states.

Builders Hardware Manufacturer Association Standards Catalog


ARCHIVE: April 6, 2019

The Builders Hardware Manufacturers Association (BHMA) is an ANSI accredited standards developing organization for building access and egress technology that education industry real asset managers find referenced deep in the architectural and electrical sections of construction contract specifications (as in “Conform to all applicable standards”).  Architects, electrical, fire protection and information and communications technology professionals usually have to collaborate on the design, construction. operations and maintenance of fenestration technologies.

Gone are the days when a door was just a door (or “opening” or “fenestration”).   Doors are now portals; an easily identifiable control point in the Internet of Things electrotechnical transformation.  There are 100’s of thousands of them on large research university campus; for example.  As we explain in our School Security Standards post the pace of standardization in public safety management and technology has increased; driven by events.  Some of the risk management can be accomplished with integrated technical solutions that are complex and more expensive to design, build, operate and maintain.

A fair estimate of the annualized cost of a door now runs on the order of $1000 to $10,000 per door (with hospital doors at the high end).

BHMA develops and maintains performance standards for locks, closers, exit devices and other builders hardware.  It has more than 40 ANSI/BHMA  standards. The widely known ANSI/BHMA A156 series of standards describes and establishes features and criteria for an array of builders hardware products including locks, closers, exit devices, butts, hinges, power-operated doors and access control products.   They are listed on the link below:

BHMA Standards Home Page

BHMA has opened one of its standards for public review that is relevant to our contribution to the security and sustainability agenda of the education facility industry; an agenda that necessarily involves a growing constellation of interacting specifics

BHMA A156.4 Standard for Door Controls – Closers.  This Standard contains requirements for door closers surface mounted, concealed in the door, overhead concealed, and concealed in the floor. Also included are pivots for floor closers. Criteria for conformance include cycle, operational, closing force, and finish tests.

Given that BHMA consensus products are largely product standards (much the same way UL Standards are product standards) it is wise to keep an eye on a related installation standards found in the fenestration sections of model building and fire safety codes and in ASTM E2112  Standard Practice for Installation of Exterior Windows, Doors and Skylights.

Comments are due May 6th.  You may obtain an electronic copies of any of the foregoing from [email protected] and send comments to the same (with copy to [email protected]).

Roxbury Community College | Roxbury Crossing, Massachusetts

The BHMA suite is on the standing agenda of our monthly Construction Specification and Design Guideline teleconference; an informal session that should interest building contractors and design professionals who prepare documents that use the general purpose clause: “Conform to all applicable standards”.   That usually means the latest standard.  See our CALENDAR for the next online meeting; open to everyone.

Abstract:  A smart way to solve the common problem of conventional door-locking system is proposed using conventional lock key methodology and it can be cloned and used by anyone. The proposed system is to make a secure door lock security system with two factor authentications. The user has to use Radio Frequency Identification tag. The tag’s data will be saved in a database. When the tag is read by the Radio Frequency Identification reader, the user has to input a pass code. After the pass code is entered, the user will receive a One-time password on his mobile device to unlock the door. The biggest advantage of proposed system is that the introduction of two factor authentication to gain the access to the door, which makes it more secure.

 

Eurocodes

CLICK ON IMAGE TO LAUNCH INTERACTIVE MAP

The Eurocodes are ten European standards (EN; harmonised technical rules) specifying how structural design should be conducted within the European Union. These were developed by the European Committee for Standardization upon the request of the European Commission.  The purpose of the Eurocodes is to provide:

  • A means to prove compliance with the requirements for mechanical strength and stability and safety in case of fire established by European Union law.[2]
  • A basis for construction and engineering contract specifications.
  • A framework for creating harmonized technical specifications for building products (CE mark).

Since March 2010 the Eurocodes are mandatory for the specification of European public works and are intended to become the de facto standard for the private sector. The Eurocodes therefore replace the existing national building codes published by national standard bodies, although many countries have had a period of co-existence. Additionally, each country is expected to issue a National Annex to the Eurocodes which will need referencing for a particular country (e.g. The UK National Annex). At present, take-up of Eurocodes is slow on private sector projects and existing national codes are still widely used by engineers.

Eurocodes appear routinely on the standing agendas of several of our daily colloquia, among them the AEDificare, Elevator & Lift and Hello World! colloquia.    See our CALENDAR for the next online meeting; open to everyone.
