Infill Housing: Complementary Daylighting and Ventilation System

HEED Analysis

Design Performance Objective

HEED Analysis: Daylighting
“The glazing system that helped with ventilation also allows an efficeint daylighting design.”
These side-by-side charts compare electric lighting required (kwhrs) during occupied hours for the daylighted building (left) and the built-to-code building (right). The daylighted building uses much less electric lighting.

This project responds to NAAB Student Performance Criteria

#19: Environmental Systems
Understanding of the basic principles and appropriate application and performance of environmental systems, including acoustical, lighting, and climate modification systems, and energy use, integrated with the building envelope

#21: Building Envelope Systems
Understanding of the basic principles and appropriate application and performance of building envelope materials and assemblies

#28: Comprehensive Design
Ability to produce a comprehensive architectural project based on a building program and site that includes development of programmed spaces demonstrating an understanding of structural and environmental systems, building envelope systems, life-safety provisions, wall sections and building assemblies and the principles of sustainability

Investigative Strategy

Model the proposed design iteratively in HEED to refine its thermal and lighting strategies. Clayton Harrison’s 600+ sq.ft. infill unit shows that the operable windows for ventilation also enhance its daylighting abilities.

Evaluation Process

Use HEED to compare the performance of the proposed design to a similar design that simply meets code.

Evaluative Criteria

Check for reduced carbon emissions and energy use as well as effectiveness of daylighting and passive strategies. HEED models all of these and provides side-by-side graphic comparisons of each system or component’s performance as well as whole building performance.

Cautions - Possible Confusions

HEED automatically calculates the performance of a code compliant building (Scheme 1) and a better-than-code model (Scheme 2) based on appropriate strategies for the climate. Students can model their buildings (Schemes 3 thru 9) and investigate various design possibilities. HEED uses Energy Plus weather files available at no cost from the DOE Energy Plus web site, which include stations for over 1000 U.S. locations and for major cities worldwide.

Range of Applicability in terms of CLIMATE

ALL

Range of Applicability in terms of TYPE

HEED is more appropriate for small buildings.

Duration of Exercise

This work was presented at the end of an eight-week comprehensive design phase. HEED models can be created in less than an hour.

Degree of Difficulty / Previous Knowledge Required

This is work assigned to a graduate student in his penultimate studio taken after all of the basic technical courses on structures and environmental systems.
