Energy-Conserving Passive Solar Multi-Family Retrofit Projects. Cycle 5, Category 1: HUD Solar Heating and Cooling Demonstration Program

摘要

A total of 14 passive solar retrofit buildings are described in this report, intended as a reference tool for neighborhood groups and others in the community development field, to help them understand what passive solar means and how to use passive solar concepts in multifamily housing. The report begins by describing the concept of passive solar energy, and discussing the various types of passive systems found in the Cycle 5 projects. Each of the 14 solar designs is described, and some of the key points raised in the discussion of passive concepts are illustrated. Each project description cites the location of the passive solar home and presents the following information: grantee/builder, designer, solar designer, price, number of units, net heated area, heat load, degree days, solar fraction of the total heat load, and auxiliary heat required. Project descriptions also include data on recognition factors (the five passive elements necessary for a complete passive system), the type of auxiliary heating system used in the building, the solar water heating system (if any), and the passive cooling techniques used (if any).
