This article shows the design of an ecological house as an alternative economic solution to a conventional house in the city of Cajamarca. Both houses were designed in a total area of 150 m2 of which only 70% was used for the built area, leaving a free area of 30% according to the Peruvian Standard. These dwellings had the same architectural distribution. After preparing the plans of both houses, we proceeded to calculate the quantities of materials and labor for the construction of each of the houses using spreadsheets.Likewise, budgets were prepared with a cost program. Finally, the budget of each house was obtained, comparing both budgets, from which it was obtained that the ecological house is cheaper than the conventional house in more than 40%, due to the environmentally friendly materials that were used in the house. ecological.

The objective of this article is to study the luminaires in homes using LED technology as an alternative solution to the high demands of active energy consumption in the department of Cajamarca -Peru. A cross-sectional descriptive methodology was used, and instruments such as data collection sheets, DIALux software and the interview were used. As a result, it was obtained that LED technology represents an alternative solution to the high demands of active energy consumption, reducing it by 50.38%, which represents a saving in soles of S/9.80 per month. Finally, it was determined that the proposed hypothesis is accepted with a variation of 0.38%, verifying that LED technology favors the reduction of active energy consumption by lighting.

The present study aimed to determine the compressive strength of masonry units using construction residues and incorporation of Synadenium Grantii, the material was collected in Urb. La Molina -The Baños del Inca Cajamarca, and the Synadenium Grantii plant in the town of Santa Barbara, this study was developed in two stages, the first consisted of the demolition of this waste and later the analysis of materials, prior to the elaboration of the units, and obtaining the optimal design of the mixture was proceeded to the second stage which was the analysis of the handcrafted units through the CINVA RAM machine provided by the Private University of the North, finally using construction residues with and without addition of 10% of Synadenium Grantii, giving a curing time of 7, 14 and 28 days, the results of compression resistance of units without addition of 41,063kg/cm 2 , 45,005kg/cm 2 were obtained, 47,025kg/cm 2 respectively, for the units generated with the addition of Synadenium Grantii they reached a resistance of 40,188 kg/cm 2 , 41,072kg/cm 2 , 43,639kg/cm 2 in 7, 14 and 28 days of curing, which did not satisfy the hypothesis, since the addition reduces the resistance of the units, however, it is determined that it is suitable for minimum uses required in 1 or 2 story dwellings.
